The Airaid Universal Air Intake Kit enables you to easily fabricate an intake for your LS swap
The introduction of the Gen III and IV LS and the Gen V LT V-8s are some of the greatest innovations for our hobby. They’re a simple drop-in engine swap because virtually everything imaginable is available through the aftermarket. Things like engine mounts are easy, but other things, such as the air intake system, typically require a bit more fabrication given how unique each LS swap is. Feeding atmosphere to the engine is critical, so installing an intake that properly places the filter away from engine heat, and preferably in an area that receives cooler outside air, is critical.
We’re working with a ’67 Camaro sporting an LS3 swap. What we needed most was a cold-air induction system capable of giving our Camaro more power via denser, cooler ambient airflow from outside the hot engine compartment. We didn’t want to mess with metal since it is harder to work with and tends to heat soak in the engine bay. Remember, as the inlet air temp goes up the ECU starts to pull timing from the engine, which is not a recipe for horsepower.
By locating the air intake as far as possible from the engine we should be able to mitigate the hot engine bay air from being ingested into the engine, which, as we said, will help with power. Besides, the whole idea of mounting the air filter directly to the throttle body, with the MAF sender shoved in there, is not the correct way and can cause tuning issues. Here’s what GM has to say about the placement of the LS MAF sensor:
“Ensure the MAF sensor is oriented correctly in the induction (it will only read correctly in the proper direction). An arrow is located on the sensor indicating correct flow direction. Verify this before welding the mounting boss, as the sensor will mount only one way in the boss.
Ensure the MAF sensor is mounted in the middle of a minimum 6-inch length of 4-inch diameter tube, and is a minimum of 10 inches from the throttle body. “
So, as you can see, slamming a filter and MAF onto the end of your throttle body falls into the “bad” category. The good new is that in most cases there’s plenty of engine bay room to fabricate a proper air intake system.
Airaid wanted to make this part of the swap easier so they offer a variety of cold-air kits for classic and late-model Chevys. We were searching for cold-air induction system bits for our ’67 Camaro when we discovered their Universal Air Intake Kit (PN 101-400), which is perfect for LS swaps where you want to get the air filter in just the right spot. We also ordered a heatshield block-off panel, designed specifically for our Camaro, from Spectre Performance (PN 4377). Both are simple, easy-to-install products that can give your classic Chevy an OE quality air intake system that will look good and not cost you performance.
1. The Airaid U-Build-It (UBI) Master Kit (PN 101-400) is a universal air intake kit designed for virtually any application. This kit features 4-inch outside diameter roto-molded intake tubes with multiple angles along with straight pipes that you can easily cut, allowing you to route the intake duct to any desired location in the engine compartment. Airaid offers several different kits with varying filter and tube sizes to handle just about any application.

2. We begin with the installation of the mass airflow (MAF) sensor adapter in the intake duct using the adapter as a template. You want to position the MAF sensor adapter where it would be installed in an OEM application upstream of the air filter. This is a commonly used one from Spectre Performance (PN 9924011).

3. We opted to use the adapter that came with our Chevrolet Performance LS wiring harness (which also included our MAF sensor). They both serve the same function so the choice is yours. The MAF sensor adapter was used as a template to draw the hole for the MAF sensor.

4. Holes were then drilled for the MAF sensor screws using the adapter as a template.

5. The intake tube has been marked for cutting to receive the MAF sensor.

6. Next, pilot holes for the MAF sensor are drilled. There are all sorts of ways to skin this proverbial cat. As long as you end up with a rectangular hole of the correct size you’ll be good to go.

7. Next, the pilot holes were drilled out to make way for the MAF sensor. We drilled a series of holes in a line and then cleaned up the edges with a razor knife.

8. The MAF sensor adapter was mounted and secured to the Airaid duct. Instead of running the bolts down, we opted to run them up through the tube. This way we won’t have nuts inside the intake tube that could vibrate loose, get sucked into the engine, and cause a really bad day.

9. The OEM MAF sensor was then secured to the adapter. It’s very important to mount the MAF sensor within reach of the wiring harness and to make sure the arrow is pointing in the right direction. We used locking nuts to make sure everything stays in place.

10. We chose to place the air filter in the far driver-side fender void (behind the headlight) where there should be more, cooler outside air. The Airaid universal kit includes the necessary piping to angle the ducting however you choose, which comes in handy for clearing radiator hoses and other obstructions. We picked up a cool (pun intended) heat block-off plate from Spectre Performance (PN 4377) and it integrated well with the Airaid system, but it’s not mandatory to use. As a bonus, the block-off plate secured the end of our air intake. Without the use of the block-off plate we would have had to fabricate a simple bracket using the supplied Airaid hardware to support the far end of the intake tube to keep it from bouncing about.

11. The Airaid ducting is measured and cut to the proper length. Plastic tends to “particle” from the heat of cutting. These particles will flake off easily. The fact that the system is made of plastic makes it very easy to work with. It will also resist soaking up a bunch of heat like metal parts would.

12. Our cut-to-fit Airaid ducting is installed here at the air filter and routing to the throttle body. The “hump hose” connector acts as a flexible coupler and gave us a few degrees of wiggle room with our installation. Our kit came with more than enough tubing to handle our project, with quite a bit left over.

13. Some LS applications, especially ones with larger aftermarket throttle bodies, will have different size openings so the Airaid kit comes with a stepped coupler that can be cut to transition from the air intake tube to whatever size throttle body you have.

14. Once the intake duct has been cut to the proper length, it is connected to the throttle body as shown. We used a coupler we already had on hand that worked great at connecting our 90mm LS3 throttle body to the 4-inch Airaid tube, but we could have just as easily used the stepped coupler provided in the kit.

15. Airaid provides the necessary positive crankcase ventilation plumbing for our cold-air intake. Many engine tuners recommend using a system like this. Keep in mind that even though we routed to the driver side you could just as easily (if your battery has been moved to the trunk, for example) gone to the passenger side of the car. Which way you go will be determined by obstacles such as radiator hoses.

16. The vent hose was installed as shown here between the MAF sensor and the throttle body. For a cleaner installation we installed it at 6 o’clock where it would be out of sight. The other end was attached to our Holley valve cover.

17. We really liked the Universal Air Intake package from Airaid, which is why we use it on nearly every Week To Wicked project we do. It works in nearly every application and since we are able to make it exactly the way we want, it fits perfectly. This kit made it easy to get a clean, custom fit air intake for our LS swap project and we actually liked the OE look. The fender support bars are part of the Detroit Speed (PN 011502) radiator closeout panel, which will seal off the top of the air filter to help isolate it from the engine bay heat.

90,000 Universal pump priming method
TOMSK ORDER OF LABOR RED BANNER OF POLYTECHNICAL
INSTITUTE named after S.M. KIROVA
Volume 115 1960
UNIVERSAL METHOD OF FILLING PUMPS
(Presented by the scientific seminar of the Department of Mining Electromechanics)
The simplest and most reliable way to prime the pumps is to deepen the sump chamber.With this method of filling, a constant backwater of water is created on the first impeller, which eliminates the possibility of cavitation and air leakage through the stuffing box on the suction side of the pump. But, unfortunately, the deepening of the pumping chambers is not provided for by the Safety Rules and is practically feasible only at newly constructed drainage installations.
In shallow pumping chambers with water present on the overlying horizon, the pumps should be filled from a supply tank with a hydraulic regulator.The siphon filling method, used in the case of water intake at a height of not more than 60-70 m, creates constant additional pressure on the glands and the suction pipeline when the pump is stopped, and therefore does not have any advantages over filling pumps through a supply tank with a hydraulic regulator. To supply water from the upper horizon to the supply tank, use the pressure pipelines of the pumps . This reduces pipe flow and makes it easier to start the engine with an open valve on the pump discharge line.
If it is impossible to deepen the pumping chamber or there is no water on the overlying horizons, it is possible to recommend (Fig. 1) the use of a supply tank with a capacity of 1 m3 with automatic replenishment by an auxiliary pump with a capacity of 20-25 ml / min, which is constantly filled from the supply tank. This pump priming method is versatile and completely reliable.
Filling pumps with accumulator tanks, bypassing water from the discharge pipeline and a vacuum pump is not reliable, since when air enters the accumulator tank, self-priming does not occur, water from the discharge pipeline often leaves, and vacuum pumps require very careful sealing pumping unit.In addition, the use of storage tanks reduces the effective suction lift of the pump.
The proposed pump priming method is applicable to both main and auxiliary installations. In pumping (auxiliary) drainage installations on the drain from the pipeline should be installed similarly to Fig. 1 small filling tank with level switch,
automatic start and stop of the pump is carried out using a water level relay in the receiving well and the filling tank, connected in parallel.
Control of filling in automation schemes with constant filling of pumps with water can be excluded.
1 — auxiliary pump; 2 – pipelines to the discharge branch pipes of the main pumps; 3 – drainage of excess water; 4 – level switch; 5 – circuit switch from automatic to manual control.

Questions and answers to them on pumping equipment
Why is the pump too loud?
There are many reasons, here are just a few:
• Wrong direction of rotation of the pump (only for 3-phase motors)
• Damage to the impeller due to abrasion and corrosion.
• Pump flow line or pump impeller clogged
• Clogged ventilation pipe
• The liquid level in the reservoir is too low
• Cause of sounds – vibrations of pipelines
• The operation of the pump in the shaft can be heard even in the building. Perhaps the mine is not soundproofed from the building; install soundproof partitions in straight rigid channels connecting the house and shaft
• The installation can be heard throughout the building. The unit is not insulated from the floor / wall, insulating gaskets are required.
Why is the pump check valve noisy?
The valve closes too slowly and hits the seat after the pump is turned off.
Replacement with a quick-closing valve, using a valve with a rubber seal, with a floating ball, setting the speed on the pump control device.
Why does the pump water hammer occur?
• Moving a large volume of liquid through a small cross-section of the pipe at the time of starting the pump
Check the duty point of the pump and the diameter of the piping to ensure that they match the fluid velocity
• Formation of air pockets in the pipeline
Installation of ventilation and air vent valves behind the check valve or at the upper points of the pipeline
• Fast output of the pump to
Replace the 2-pole motor with a 4-pole one or use a soft starter / frequency converter
• The water pump is started very often
Set the speed on the control unit
• Quick-closing valves were installed in some sections of the pipeline
Replace the valve with a conventional one.
Why are the pump and discharge line clogged with deposits?
• Formation of deposits occurs at reduced flow due to reduced fluid velocity
Check the operating point of the pump and the diameter of the piping to ensure that they match the fluid velocity
• Too frequent activation for pumping small volumes
Recalculate the height of the liquid level to turn on the pump (increase the pumping volume during one pump operation cycle), if necessary, increase the speed on the control device.
Why is the pump control unit giving an overload signal?
• Line voltage drop. Check the voltage in the network
• The viscosity of the pumped liquid is too high, which causes an overload of the motor
Install a smaller impeller or other motor
• Pump operation on the right side of the curve. Limit the pump capacity by means of shut-off valves on the discharge line
• Motor temperature rise too high. Check the number of starts and stops and, if necessary, limit the switchgear by setting the switching frequency
• Wrong direction of rotation of the pump (only for 3-phase motors).
To set the correct direction, swap two phases (cores of the pump power cable)
• Loss of one of the phases
Check the cable connection contacts and, if necessary, replace the defective fuses.
Why is the pump not delivering the required power?
• Wrong direction of rotation of the pump (only for 3-phase pumps)
To set the correct direction, swap two phases (cores of the pump power cable)
• Damage to the impeller due to abrasive wear and corrosion
Replace damaged parts (e.g. rusty impeller)
• Plugged pump flow or impeller
• Clogged or stuck check valve
• The valve on the discharge pipeline is not fully open
Fully open the valve
• Particles of air or gas in the pumped liquid
Provide deep immersion of the pump in water or install baffle plates in order to prevent the water jet from entering the area near the pump
• Clogged ventilation pipe
Check and clean if necessary.
When does pump cavitation occur and what are the ways to eliminate it?
• The ventilation pipe is clogged (or its diameter is too small) at a high temperature of the pumped liquid
Clean or install a new larger diameter pipe
• Long suction line for pumps for dry installation
Find another suitable pump
• Particles of air or gas in the pumped liquid
Provide deep immersion of the pump in water or install baffle plates in order to prevent the water jet from entering the area near the pump
• Plugged or slagged inlet pipeline
Clean the pump supply line or shaft; clean the hydraulic part of the pump
• High temperature of the pumped liquid
Select another pump
• The pump runs on the right side of curve
Select another pump; increase the resistance on the pressure pipeline by installing artificial resistances such as additional elbows, small-diameter pipeline.
How to independently equip a sewage pumping station in the country?
It is best to use a ready-made solution and purchase a modular sewage pumping station, which is a completely sealed plastic well, inside which fittings are located for mounting a fecal pump. The fecal pump itself is selected separately, depending on the required performance and pressure. You will also need to buy a control cabinet for a sewage pumping station, which provides automatic activation of fecal pumps depending on the water level and operates from float or pneumatic water level sensors.Usually, ready-made wells for a sewage pumping station have a depth of about 2 meters and a diameter of 1 meter. To install it, you will need an appropriate foundation pit, into which you must also bring the supply sewer line from your house and subsequently connect it to the plastic container of the sewer pumping station. Usually, wastewater is fed into the storage well by gravity, but it is also possible to discharge wastewater under pressure if sewage pumping units are installed in the house. The modular scheme makes it easy to mount and dismantle the sewage pumps inside the tank, you just have to lay the pressure manifold, which is securely fixed to the plastic tank with threaded connections.Due to the use of fecal pumps with a grinder, the pressure sewer manifold can be made with pipes of small diameter. It remains only to install level sensors inside the sewage pumping station and connect the fecal pumps to the control cabinet using special connectors. The control cabinet of the modular sewage pumping station does not require any additional settings and it is best to leave the factory settings. It remains only to tightly close the sewer well with the special cover that comes with the delivery set and the sewer pumping station is ready for your home.
The basement in the house was flooded, how to pump out the water if there is no sump for the drainage pump?
There are drainage pumps in which the engine is cooled by the pumped liquid passing inside the pump housing. For automatic operation of the drain pump, instead of a standard float level sensor, it is better to use a sensor sensor that is triggered at a minimum water level on the floor surface. Take a look at the HOMA C237WF Drainage Pump.
How to disassemble and clean the fecal pump yourself?
Fecal pumps are complex technical devices and it is better not to disassemble them without specialized training.Inside the fecal pump, a special oil is used to seal the electric motor, and when you try to open the pump housing, this oil will most likely leak out, allowing moisture in the pump to get onto the electric motor winding, which will cause the pump to fail. Your best bet is to go to a specialized service center, where professionals will clean and replace the faulty parts of your fecal pump.
How long does it take to service the sewage pump?
It all depends on the amount of time that the pump has been running.Typically, for industrial sewage pumps, control panels are used, which independently monitor the cycles of switching on and off the pumps, giving a signal for the production of service. For low-power sewage pumps, it is best to carry out service once a year before the start of the season, which consists of changing or adding oil, as well as cleaning the working chamber. The impellers are also inspected and, if worn, they are replaced.
Why are 4 level sensors used in the control system of a sewage pumping station?
This is most likely a sewage pumping station with two fecal pumps.Let’s look at how level sensors work from the bottom up.
• Responsible for shutting off the sewage pumps in the event of a drop in the liquid level below the level of the installed pumps, protecting the sewage pump from running dry.
• Turns on the fecal pump for evacuation.
• Simultaneously connects the second faecal pump, as an emergency discharge occurs, exceeding the design capacity of the faecal pump.
• Overflow of the storage tank of the sewage pumping station, the sensor triggers an alarm in the control cabinet.
What air pressure must be pumped into the tank of the pumping station?
In pumping stations equipped with a hydraulic tank, an air pressure between the casing and the membrane is usually used equal to 1.2 – 1.4 atmospheres. To check the air pressure inside the pumping station, it is enough to remove the casing from a conventional nipple installed on the tank body, and in case of a pressure drop, pump air there using a conventional automobile pump.
How to extend the cable for a submersible borehole pump?
Submersible borehole pumps are supplied with a short cable pulled out of the pump, since the length of the cable is selected based on the depth of the well and the mark at which the borehole pump will be submerged.The connection of a waterproof cable is made using a special thermal coupling, consisting of stamps and a waterproof winding, which, after connecting the ends of the cable from the pump with the help of stamps, is put on top and welded with a heat hairdryer, providing a reliable and tight connection.
The pump cracks terribly when switched on, what should I do?
Most likely a foreign object has got into the pump chamber, try to remove it. Also, the noise when the pump is turned on may be associated with malfunctions of the pump running gear (breakdown of the impeller, displacement of the electric motor shaft, etc.).you will need to disconnect the pump and send it to the service center for troubleshooting. In some domestic pumps and pumping stations, the sound effect serves to signal an alarm when the pump is running dry, check the free flow of water to the suction pipe of the pump.
How to lubricate the bearing of the sewage pump?
Modern models of sewage pumps use bearings that do not require lubrication for the entire period of operation. The only place where lubricants are used is the oil chamber to seal the fecal pump motor.
How to install and adjust the faecal pump yourself?
Usually, sewage pumps are installed inside the sewer well using a special automatic coupler, which is rigidly attached to the wall of the well. A pressure pipeline is already being brought to it, through which the sewage is pumped out, and guides are attached to it, along which the fecal pump can be raised and lowered as if on rails for maintenance. An easier way is to buy a fecal pump with a built-in stand.To install such a fecal pump, it is enough to simply connect a pressure manifold in it and lower it to the bottom of the well. Usually, all sewage pumps are supplied with an automatic control system for the sewage pumping station, consisting of a control cabinet and a level sensor. After installing the sewage pump, it is necessary to fix the float level sensor in the well at the required depth and, using a special connector, connect the sewage pump to the control cabinet. There is no difficulty in self-installation of a fecal pump, all automation is supplied completely ready for use, and does not require additional settings.
How to remove sewage from the basement?
Compact sewage pumping units are used to pump out sewage from rooms located below the level of the sewer collector. Typically, such a sewage pumping unit consists of a plastic tank and a fecal pump built into it, which provides crushing and supply of fecal waste under pressure to a common sewer collector.
What to do if the basement is flooded?
Any drain pump is suitable for pumping water out of the basement.If you have a sump on the basement floor, then use drainage pumps with built-in float level sensors to pump out water, and if there is no sump for the pump, then buy a drainage pump with a level sensor. Remember, the drain pump is only a temporary measure that allows you to pump out water from the basement, after draining the basement, waterproof the foundation of your house to avoid repeated flooding of the basement.
Why doesn’t the pumping station draw water from the well?
In order for the pumping station to suck water from the well, it is necessary that the hose lowered into the well and the working chamber of the pumping station are completely filled with water.At all pumping stations, on top of the working chamber, where the suction hose or pipe is connected, there is a screw that serves to fill the suction pipe with water. Gently unscrew it and pour water into the hole until it pours out. To prevent water from the pumping station from going back into the well through the suction pipeline, be sure to install a check valve at the end of the pipeline lowered into the well.
How to get rid of the stench from a sewage pumping station?
Modern sewerage pumping stations and installations have completely sealed structures that exclude the entry of unpleasant odors into the environment.You should order a sealed cover for your sewage pumping station and take care of the small ventilation hole (air supply to the sewer pumping station is necessary for the fecal pumps to function properly). After installing the sealed cover on the sewage pumping station, make an air duct from a small diameter pipe and take it to the border of the site, where the smell will not irritate anyone.
Why do you need a cutting device in a faecal pump?
A cutting device or grinder is used in fecal pumps for mechanical destruction of all fractions that enter the pump along with sewage.Typically, sewage cutter pumps are used in first-lift sewage pumping stations where sewage must be collected and fed over a long distance into a large sewage sump or sewer. Usually, fecal pumps with a grinder create a high pressure and pump sewage drains hundreds of meters, and also capable of pushing through sewer headers under pressure. Another important feature of fecal cutter pumps is the use of small diameter pipes as a pressure header.
When the machine is turned on in the control cabinet, the pump does not work, what should I do?
The power supply to the pump needs to be checked. If the light indication in the pump control cabinet does not light up, then the electric current is not supplied to the control cabinet, check the connection of the pump control cabinet to the mains. If the light indication in the pump control cabinet is on, and the pump does not work, then most likely there is a cable break between the pump and the control panel or the electrical connection of the thermal coupling is faulty, with which the pump is usually connected.You can also remove the front panel in the control cabinet and check the connection of the connectors inside, all connectors must be firmly fixed.
The pump is running, but does not pump water, what should I do?
This may be due to the airing of the supply line to the pump, usually occurs when the check valve for pumping stations and submersible borehole pumps is inoperative. You will need to disconnect the pump and bleed the air. But most likely the reason is the drop in the liquid level below the pump, such a malfunction is especially relevant for submersible pumps.It will be necessary to lower the pump below the level of the pumped liquid. Also, this behavior of the pump may be due to the lack of fluid supply to the pump.
We are planning to purchase several slurry pumps and understand that this service is considered a heavy duty. What guidelines should be followed regarding pump sizing based on good wear resistance?
Pump wear depends on the pump design, the abrasive nature of the slurry, the specific application or duty conditions, how the pump is applied or selected for duty and actual operating conditions.The wear inside the pump varies greatly depending on the speed, concentration and influence of the angle of the particles. Typically, the heaviest face impeller seal is the suction area of the liner, followed by the vane inlet and outlet. The amount of body wear and location also varies with the shape of the manifold and as a percentage of actual operating conditions versus the best flow point of efficiency.
Only with maintenance, in many parts of slurry pumps, wear can last for years.Services, such as transport of high concentration and very abrasive or large particulate matter, can sometimes shorten the length of a part by several months. Larger pumps with thicker sections, more material wear, and slower operating speeds can improve life in all applications, although the significant associated cost increases may not be justified in some cases.
Analytical and numerical models are available to make quality wear forecasts.Their limitations and the variability of slurry services are such that contacting component life predictions are still only good estimates and should not be used for assurance. These estimates are usually based on the specified operating condition of the pump and can vary significantly if the pump is operated under substantially different conditions. Using such an analysis, life cycle cost (LCC) estimates of capital, power, wear, and other costs associated with a pump can be used to estimate the optimal balance between different pump designs.This analysis is largely theoretical, however, as clothing can be unpredictable on active duty.
Ranking slurry into light (class 1), medium (class 2), heavy (class 3) and very heavy (class 4) services, as shown in Figure 184.108.40.206a, provides a practical tool for pump selection and, when combined with By table 12.3.5a, the means to recommend the limiting head of the pump.
The class boundary lines between the service areas of the schedule are approximately the limits of permanent wearing modified for practical reasons and experience.Capital and operating cost considerations are such that different (higher specific velocity) designs can be used for a lighter service class.
The suspension service rating shown in Figure 220.127.116.11a is based on aqueous solutions of silica based on solid pumping (Ss = 2.65). It can also be used as a guide for mineral slurries if the equivalent specific gravity in the slurry is used to determine the class of service.
Further information on slurry pumps can be found in ANSI / HI 12.1-12.6, Centrifugal (Centrifugal) Slurry Pumps for nomenclature, definitions, applications and operations.
Besides the obvious financial benefits of energy savings, what are the other important economic benefits of a pump for system optimization that affect the total cost of ownership?
When conducting pump optimization systems analysis, it is necessary to look beyond energy savings to capture the less obvious economic drivers that can have a positive impact on bottom line.Factory and corporate managers’ incentives tend to minimize upfront costs as a means to increase the company’s bottom line when considering fixed asset investments.
Decision makers have historically been more inclined to invest in projects that translate directly to the bottom line, such as capacity expansion versus declining energy demand. Most energy efficiency projects have additional economic benefits that are overlooked, including the following:
Increased productivity and product quality
High reliability and low maintenance
Better environmental compliance
Reduction of by-product waste
Increased capacity and throughput
Improvement of labor safety
What types of connections can be used on pumps and what are their functions?
The main function of a pump clutch is to provide a flexible mechanical connection between two in-line shaft ends.Essentially, couplings connect two pieces of rotating equipment. Their function is to transfer power, allowing varying degrees of movement to displace, no end.
Three main types of couplings: mechanical, elastomeric and metal. Mechanical element types generally gain their flexibility from the combination of loose-fitting parts and rolling or sliding of mating parts. They generally require lubrication if only one moving part is made of a material that provides its own lubrication.
Types of elastomeric elements obtain their flexibility in tension or compression of the material. Metallic element types obtain their ability to withstand displacement and expansion from bending of thin metal discs or diaphragms.
The type of pump coupling to be used is related to the power required by the pump. A small pump can be considered a pump up to 100 horsepower. Since these pumps require relatively low power, they can use connections where the flexible element can be easily checked and replaced if necessary.
If there is a connection due to insufficient high torque load or excessive displacement, the flexible connector is usually replaced. However, as a rule, not to the detriment of other components. Coupling types for small pumps include flexible mesh, disc, and elastomers. In some small gear link designs, lubrication is not needed because the liner is made of nylon or plastic.
Medium power pumps use flexible gear meshes, disc and elastomeric couplings.These connections will have good durability, with premature failure only occurring when improper application or installation, lack of proper lubrication or excessive displacement is a factor. Elastic connections are often used for applications in which very high cyclic peaks occur because they reduce the torsional loads on the equipment.
High horsepower pumps are essential to ensure continuous operation in most facilities, and therefore the selection and installation of their connection is critical.For high speed, high torque, high performance transmission, disc or diaphragm couplings are often specified by the user.
Couplings are high-tech designs that are manufactured and balanced specifically for applications. Many of these connections use special alloys and fasteners.
When buying a new centrifugal pump, what type of acceptance test is recommended?
Buyers of centrifugal pumps should specify an acceptance test that will check the flow rate, production manager and required power.The costs associated with acceptance tests and special tests should be clearly stated in the contract. Setting tighter acceptance tolerances can increase testing costs and increase lead times. When NPSH testing is specified, test costs will be higher, since the pump test must pass another, more laborious test, often performed with different test installations requiring additional installation and tear-down time.
For lower throughput tolerances, tighter manufacturing tolerances are required, which greatly increases cost and lengthens delivery times.Sand-cast forms are the most expensive, but the most tolerant. Casting techniques will provide superior surface quality and most consistent measurements.
Molding equipment casting costs can be two to four times that of sand casting. A high production volume is needed to justify the additional cost of this equipment. Many hours of manual labor can be required to produce sand casts at tight, repeatable tolerances.
Machining parts to smaller tolerances can increase labor costs by 50 percent and increase the time it takes to make a part to the required tolerance.Reduced tolerance for increased costs due to the need for additional maintenance in the production process and the potential for increased scrap speed. The impeller may need manual work to obtain the required performance. The impellers must be axially positioned for optimal alignment with the casing to generate the required head and high efficiency.
Should be used as a guide. For commonly manufactured pumps, users may consider a certificate of conformity rather than actual testing.
What are pump characteristics?
Creating a pump curve requires measurement of flow rate, head and power. Based on this information, the pump efficiency can be calculated. The efficiency of a pump curve is usually related to the power of the input shaft. Published hydraulic power efficiency of the pump production divided by the mechanical power at the pump shaft. The efficiency published is only what is in the pump. From a testing standpoint, the most accurate way to obtain power data is by directly measuring torque and shaft revolutions.This is done using a torque converter and tachometer. These values are used when calculating the power to the pump.
A less accurate method, but it can be pointed out, is a string test using a complete assembly of the engine, pump and drive (eg gearbox, belt drive, etc.). The accuracy of this test will be lower than when the pump is being tested. In this case, the power is measured by the power of the engine. Pump shaft power is calculated based on published motor and drive efficiency.Since these efficiencies are not exactly known, this method is less accurate.
When the VFD is used as part of a string, it becomes difficult to get an accurate value for the input power to the pump shaft. The wattmeter cannot accurately measure the power from the VFD to the motor due to the non-sinusoidal IF signal. The wattmeter can measure power in the VFO. However, when the power consumption in the VFO is measured, the VFD efficiency must be known to calculate the IF motor power. This information may be available, but this adds another layer of error as the motor efficiency will vary with the non-sinusoidal signal at the output from the VFO.(Although many VFDs provide a power output measurement, this measurement is only approximate and not accurate enough for acceptance testing. This reading does not count motor efficiency degradation when operating on VFD power.)
String test with VFD may be required if the customer specifies that the VFD be used for test strings. It may also be needed when a client wants to have curves in a range of speeds. In both cases, the suggested procedure for a single test without VFD is to start the engine directly through the line.This allows the full head-generating efficiency curve to be produced at rated speed. The VFD can be connected to the motor, and the head power curves can be produced at the required speeds without any power measurements.
Influence of factors for calculating pump efficiency for various configurations. Contains factors needed to calculate pump efficiency for various configurations. The test string cannot measure the efficiency of the pump motor. In this case, the pump must be checked separately if accurate PTO measurements are required.The curves of a pump manufacturer will often only provide the end user with the required shaft power. Further investigation may show that this information is provided with the pump being sealed packaging, rather than a mechanical seal that can absorb additional power. In terms of energy consumption, this data does not provide the user with the real cost to operate the pump.
Wire-to-water efficiency and energy efficiency curves are more useful, but rarely requested.Wire-to-water performance can be measured with all configurations in Figure 2 by placing a wattmeter at the motor inlet or VFD. This data will allow the end user to know the true power consumption of the system pump and estimate the true cost of ownership.
Some applications involve a solution of foam in a liquid that will affect pump performance. What should be done when choosing centrifugal pumps for such applications?
Foam is a porous medium liquid (suspension) that occurs naturally or is created for a specific purpose.The natural appearance may be due to the nature of the ore processing in the mining industry, creating a common nuisance in many cases.
Foam is created to separate minerals, floating product from waste and vice versa. It is designed to aerate the suspension through the injection of air during agitation with the addition of polymers to increase the surface tension. This creates bubbles which the product or waste adheres to, which allows for the separation and collection of the demanded mineral for further processing.
The transfer of foam from centrifugal slurry pumps is a special purpose application often found in chute flotation circuits. A very large part of the air in the foam is handled disrupting the normal relationships that are used to predict pumping performance and requires a unique approach in the selection and application of pumps for this service.
Depending on the process, the type of slurry or foaming agents used, a certain amount of air or gas will separate from the foam and can lead to pump performance problems.Changes in performance due to this air or gas can be quantified based on various factors such as pump geometry, specific speed and suction pressure.
However, it is almost impossible to determine with a reasonable degree of accuracy that the amount of free air or gas will separate from the foam at the impeller inlet. This problem requires the selection of a pump that can successfully handle the foam application.
The usual approach to oversized pump for application is using the “foam factor”.Foam factor is a multiplier that increases the productivity of the design process to allow for an increase in the volume of passing gas caused by the foam.
Foam factor is usually specified by the purchaser of the pump and based on previous experience of the plant. Factors are usually in the range of 1.5 to 4, but can be as high as 8. Many factors affect the foam size factor. These can include the viscosity of the liquid, the size of the grind of the mineral, and the chemistry used in the process. The type of pump chosen will also have an impact on the foam factor used, and the pump manufacturer should be consulted for sizing recommendations.Some typical vertical pump foam common process factors are shown in Table 12.3.3. These are only approximate values. The most reliable factors will come from the end users.
ANSI / HI 12.1-12.6 Centrifugal (Centrifugal) Slurry Pumps, Section 12.3.3 includes additional information on foam pumping which will answer other questions. A new edition of this standard is expected to be released this summer.
Is there a standard procedure for measuring airborne sound from industrial pumps?
Yes.ANSI / HI 9.1-9.5 General Recommendations for Pumps includes Section 9.4: Airborne Sound Measurement. The purpose of this standard is to provide uniform test procedures for the measurement of airborne sound from pumping equipment.
This standard applies to centrifugal, rotary and reciprocating pumps and pumping equipment. This indicates acceptable and reasonable operating conditions and procedures for use by laymen as well as acoustic engineers.
This standard does not apply to vertical pumps submerged in a wet pit. In this standard, a sound pressure level of 20 µPa (0.0002 µbar) is used as a reference.
What is the pump noise level and what parameters should be considered when choosing a pump or pumping station?
Let’s start by finding out what causes the noise. There are several reasons:
1. The existing imbalance of the rotating parts of the pump and the electric motor.
2.Cavitation (collapse of air bubbles in water).
4. The movement of water through pipelines.
As you can see, the noise level directly depends on the design perfection of both the borehole pump or pumping station itself, and other elements of the water supply. As a rule, the noise level from a running pump or pumping station reaches 60 – 90 dB, and sometimes even more. Even in advanced pumps such as the Grundfos SQ or SQE, as well as in Grundfos MQ pumping stations, the noise level reaches 55 dB.In the Italian pumping stations Uni-Jet already 70 dB, and in domestic equipment these indicators are selected to the level of 80-90 dB. And this despite the fact that according to sanitary standards, the maximum noise level should not exceed 30 dB!
What factors cause the pump to vibrate and how can the cause of the vibration be determined?
Factors influencing fluctuations are:
Mechanical – unbalance of rotating parts
Mechanical – imbalance with abrasive liquids
Pump and motor, natural frequency and resonance
Miscellaneous mechanical problems
Hydraulic – resonance in the pipeline
What are boilers for boilers and what are these pumps for?
Serve for a boiler room for uninterrupted provision of the optimal raw water pressure immediately before chemical water treatment and for supplying chemically purified water to a container with hot water (hot water tank), as well as to a deaerator.
This pump helps to maintain the required liquid level in the hot water tank. You need to choose it, too, taking into account the real conditions in which it should work. The ability to pump a certain volume of liquid per unit of time is one of the main criteria.
What is bearing sealing used for and how does it work?
An important condition for the reliable operation of bearings is a reasonable choice of seals that protect the bearing cavity from dust, moisture, abrasive particles from the environment and prevent the leakage of lubricant.The design of the selected seal depends on the type of lubricant, the operating conditions and operating conditions of the bearing assembly, and the degree of its tightness.
According to the principle of operation, the seals are divided into contact ones, in which the sealing is carried out due to the tight fit of the sealing elements to the moving surface of the shaft; non-contact – sealing in which is carried out due to small gaps of mating elements; combined, consisting of a combination of contact and non-contact seals.
The main types of contact seals are stuffing box and lip seals.
Why monitor the pressure in centrifugal pumps?
Malfunctions in centrifugal pumps result from non-compliance with the conditions for the entry of liquid into the pump. If in some areas of the pump the pressure drops to the pressure of saturated vapors, then in these areas the liquid will begin to boil with the formation of air pockets in the channel, which violate the smoothness of the flow.
This phenomenon is called cavitation, which can occur both in the stationary and in the moving part of the pump.
Cavitation is accompanied by strong noise, cracking, vibration of the pump, causes destruction of metal, lowers the head, productivity and efficiency of the pump. In addition to mechanical destruction of the metal, cavitation causes corrosion. Cast iron is destroyed especially quickly. More resistant metals – bronze, stainless steel – are also destroyed. Therefore, cavitation must not be allowed in the operation of the pump, and the suction head must be such that the occurrence of cavitation is impossible.
During the operation of centrifugal pumps, cavitation can occur when the liquid level in the suction tank drops below the design one, the temperature of the pumped liquid rises, and the pump is incorrectly installed and installed.In order to reduce losses in the suction pipeline, reduce, if possible, its length, make it more straight, install a minimum amount of fittings, avoid air bags.
What is a balanced mechanical seal and where is it used?
A mechanical seal is a sealing device that forms a rotating seal between a moving part and a stationary part. They have been designed to overcome the drawbacks of stuffing box packing.Leakage can be reduced to the level of compliance with state environmental standards
regulatory authorities and maintenance and repair costs can also be reduced.
Advantages of a mechanical seal over conventional packing:
1. No or limited leakage of the product (meets the standardization of the composition of vehicle emissions).
2. Reduced friction and power loss.
3. Elimination of shaft or sleeve wear.
4. Reduced maintenance costs.
5. Suitable for use at higher pressures and more aggressive media.
6. A wide variety of designs allows mechanical seals to be used in nearly all pumps.
The balanced mechanical seal includes a simple design change that reduces hydraulic forces trying to close the mechanical seal. Balanced seals have a higher pressure limit, less stress on the sealing surfaces and generate less heat.This makes them most suitable for pumping liquids with low lubricity and high vapor pressure, such as light hydrocarbons.
What are the requirements for the suction piping of a centrifugal pump?
The suction pipeline is one of the critical elements of the pumping station. The following requirements are imposed on it: it must be sealed, as short as possible with the smallest number of fittings (elbows, bends, tees, transitions, etc.)), should not have places for the formation of air pockets. The tightness of the suction piping is achieved by carefully joining the pipes and fittings installed on the piping. The material for the suction line can be steel and sometimes cast iron pipes. Wooden, asbestos-cement and reinforced concrete pipes do not provide complete tightness, therefore, their use is not allowed.
Steel pipes can be joined by welding or flanging.Welding ensures that the pipeline is sufficiently tight. The use of a flanged connection is possible provided that the suction line is not covered with earth. Pipes laid in the ground must be covered with anti-corrosion materials. In loess and other subsidence soils, pipes should be laid without backfill. Only after the end of the subsidence, the trench can be filled up.
The assembled suction pipe must have a gradual rise to the pump (slope not less than 0.005) so that the air trapped in the suction pipes can move freely with the water to the pump.In order to reduce pressure losses, the suction pipeline should be as short as possible, not have sharp turns, expansions, contractions and unnecessary fittings.
Air pockets must be avoided to ensure correct operation of the suction line. These bags can occur in elevated locations and sharp bends in the pipeline.
Suction pipes can be fitted with suction or foot valves, suction funnels, screens, gate valves, elbows, tees and transitions.
How to calculate and avoid water hammer pressure?
Depending on the propagation time of the shock wave and the shut-off time of the gate valve (or other shut-off valves) t , as a result of which a water hammer occurred, 2 types of blows can be distinguished:
Full (direct) water hammer if t <
Incomplete (indirect) water hammer if t >
Direct water hammer occurs when the closing time of the valve t3 is less than the shock phase T , determined by the formula:
Here is the length of the pipeline from the impact point to the section in which constant pressure is maintained, is the speed of propagation of the shock wave in the pipeline, is determined by the formula N.E. Zhukovsky, m / s:
de E – bulk modulus of liquid,
ρ – liquid density,
– speed of sound propagation in liquid,
Etr – modulus of elasticity of the pipe wall material,
D – pipe diameter,
h – pipe wall thickness.
For water, the ratio depends on the material of the pipes and can be taken: for steel – 0.01; cast iron – 0.02; can – 0.1-0.14; asbestos-cement – 0.11; polyethylene – 1-1.45
Coefficient k for thin-walled pipelines is used (steel, cast iron, a / c, polyethylene) equal to 1.For reinforced concrete
coefficient of reinforcement with annular reinforcement ( f – cross-sectional area of annular reinforcement per 1m of pipe wall length). Usually . The pressure increase during direct hydraulic shock is determined by the formula:
where Vo is the speed of water movement in the pipeline before the valve is closed.
If the closing time of the valve is longer than the impact phase ( tz> T ), such a blow is called indirect. In this case, the additional pressure can be determined by the formula:
The result of the impact is also expressed by the value of the pressure increase H , which is equal to:
with direct impact
with indirect impact
Methods for preventing the occurrence of water hammer:
• Based on the Zhukovsky formula (which determines the pressure increase during a water hammer) and the values on which the propagation velocity of the shock wave depends, in order to weaken the force of this phenomenon or completely prevent it, it is possible to reduce the velocity of fluid movement in the pipeline by increasing its diameter.
• To reduce the strength of this phenomenon, increase the shutter closing time
• Installation of damping devices
How far from the surface of the water should the pump be installed in the well?
The pump in the well is installed at such a depth that the lower edge of the pump is 25 – 30 cm upwards from the bottom, such a distance is necessary so that the pump, when drawing water, does not also capture sand from the bottom of the well.
How does a gas dissolved in a liquid affect the performance of centrifugal pumps?
Gases dissolved in a liquid can provoke cavitation.Cavitation in centrifugal pumps is a hydrodynamic phenomenon and depends on the hydrodynamic properties of the working parts of the machine and the physical properties of the liquid. Cavitation in pumps usually begins when the pressure drops to a value equal to or less than the pressure of the saturated vapor pressure and is accompanied by disruption of the flow continuity with the formation of cavities saturated with steam and gases dissolved in the liquid.
The phenomenon of cavitation in pumps is accompanied by liquid boiling and is a thermodynamic process determined by the properties of the liquid: pressure, temperature, latent heat of vaporization, heat capacity.
The consequences of cavitation in pumps are accompanied by symptoms that adversely affect the operation of the pump.
Noise and vibration occur when cavitation bubbles are destroyed in a high-pressure zone. The noise level depends on the size of the pump. Cavitation noise appears as a characteristic crackling sound in the impeller outlet area.
A decrease in pump parameters in the presence of developed cavitation has a different effect for pumps with different speed coefficients and depends on the value and influence of the cavitation zone.At low speed, the parameters drop sharply. Pumps with a high speed factor are characterized by a gradual decrease in parameters. If the cavitation zone occupies the entire section of the channel, then there is a breakdown (cessation) of the pump supply.
Cavitation destruction of materials (pitting) occurs during prolonged operation of the pump under cavitation conditions in the places where bubbles collapse. Pitting takes place both during initial and advanced cavitation.
What is pump rotor balancing and why is it done?
The shaft with the parts fitted on it is called the pump rotor.The rotors of centrifugal pumps are balanced, and for small pumps static balancing is performed, and for large ones – static and dynamic balancing.
In the process of round-the-clock operation, the main components of centrifugal pumps (shafts, bearings, oil seals and mechanical seals) are constantly worn out, the axial run of the rotors increases, the balance is disturbed, the connecting elements of the half couplings wear out.
All rotating parts or assemblies, the imbalance of which can cause disturbances in the operation of mechanisms, their vibration, premature wear, etc., should be subjected to balancing.n. Static balancing is used to balance bodies of revolution with a large ratio of diameter to width – narrow pulleys, gear wheels, individual disks of centrifugal pumps and turbomachines, etc. Static balancing of long bodies of revolution (wide pulleys of centrifuge drums, rotors of electric machines, rotors of multi-wheel centrifugal pumps and turbomachines, shafts, etc.) does not give satisfactory results, and dynamic balancing is necessary for such parts.
What is the efficiency of a pumping system and how to improve it?
The pump is always running in the system, so the main method to improve the energy efficiency of pumps is to optimize the entire system based on a quality survey.
Pumping equipment is the most energy-consuming equipment used in the economy.
The Finnish Research Center conducted a survey of 1,690 pumps at 20 enterprises in Finland, the results of which showed that the average efficiency of the pumps averaged 40%, while 10% of the pumps operated with an efficiency below 10%!
The main reasons for the ineffective use of pumping equipment were recognized: resizing (selection of pumps with a higher flow and head) and regulation of pump operation modes using valves.
World experience determines the main reason for the incorrect selection of pumps for the requirements of the system. Thus, according to the five leading pumping equipment manufacturers in the United States, more than 60% of the pumps sold are operated outside the operating range, and in 95% of cases, consumers are to blame for this, who provided incorrect initial data.
The main reasons for the operation of pumping equipment not in optimal mode:
1. Designers lay down pumping equipment with a margin, in case of unforeseen circumstances or development prospects, which subsequently leads to a decrease in pressure, throttling and loss of efficiency during operation.
2. Changes in the parameters of the hydraulic network over time (corrosion of pipes, replacement of pipelines, etc.).
3. Wear of fittings, wear of pumps.
4. Change in water consumption due to population growth or decline (enterprises cease to exist, meters are installed, and systems designed in Soviet times do not correspond to the new reality).
5. Replacement and installation of new elements in the system with different hydraulic characteristics.
6. Regulation of pump operation modes.
Methods to reduce energy consumption in pumping systems:
→ replacement of pumps with more efficient ones – 2%;
→ replacement of electric motors – 1-3%;
→ impeller trimming – up to 20%, on average 10%;
→ cascade control with parallel installation of pumps – up to 10–30%;
→ use of additional tanks for operation during peak loads – 10–20%;
→ simple reduction of the pump speed with unchanged network parameters – up to 40%;
→ replacing the flow control by a gate valve with a frequency converter control allows to reduce energy consumption by up to 60%;
We want to check the technical data of the pump.How can I do that?
The main characteristic is the dependence of the pump flow on its head, the so-called Q-H characteristic. Power consumption and efficiency are already a consequence of the pump’s work to create the flow Q and the head H, which are the purpose of purchasing the pump.
The performance of each pump is determined only by testing it. Analytical methods for constructing characteristics are very complex and do not give sufficiently reliable results.
The pump specifications are obtained by testing.
When testing the pump, the liquid is in a closed loop. The liquid taken by the pump from the reservoir is fed into the pressure network, which consists of a section of the pipeline with a flow meter and a throttle valve, and then returns to the reservoir.
In this case, all the energy received by the liquid in the pump is absorbed mainly in the throttle valve. By closing and opening the valve, it is possible to change the pump flow from zero from zero to a certain maximum value. The number of revolutions of the pump during one experiment is kept constant.
At different openings of the throttle valve, measurements are made: flow, head, discharge pressure, suction pressure, fluid temperature and power consumed by the pump.
How is the wear resistance of a slurry pump ensured?
There are several options for selecting wear protection for slurry pumps:
• Impeller and housing made of hard metal with various alloys of white iron and steel.
• Elastomer impeller and casing protected with elastomeric liners.Elastomers are usually rubbers of various qualities or polyurethane.
• Combination of hard metal impeller and elastomer lined casings.
Material selection for wear parts is a balance between wear resistance and cost of wear parts.
There are two strategies for wear protection:
1. Wear-resistant material must be hard enough to withstand the cutting action of impact particles!
2.The wear-resistant material must be flexible and capable of absorbing impacts and repelling particles!
The selection of wear resistant parts is usually based on the following parameters:
• Solid particle size (specific gravity of solid particles, shape and hardness)
• Pulp temperature
• pH and chemicals
• Rotational speed of the impeller
The main wear resistant materials in slurry pumps are hard metal and soft elastomers.
Ceramic materials are available as an option for some pump types.
What are the requirements for boiler pumps to be used in boiler rooms?
Power supply to boilers can be group power supply with a common supply line for the connected boilers or individual power supply for only one boiler.
The inclusion of boilers in one power group is allowed provided that the difference in operating pressures in different boilers does not exceed 15%.
Feed pumps connected to a common line must have characteristics that allow parallel operation of the pumps.
To supply boilers with water, it is allowed to use:
a) electrically driven centrifugal and piston pumps;
b) steam driven centrifugal and piston pumps;
c) steam injectors;
g) hand-operated pumps;
e) water supply network.
The use of a water supply system is allowed only as a backup power source for boilers, provided that the minimum water pressure in the water supply system in front of the regulating body of the boiler supply exceeds the design or permitted pressure in the boiler by at least 0.15 MPa (1.5 kgf / cm2).
The steam jet injector is equivalent to a steam driven pump.
A plate must be affixed to the body of each feed pump or injector stating the following information:
a) the name of the manufacturer or its trademark;
b) serial number;
c) nominal flow at nominal water temperature;
g) the number of revolutions per minute for centrifugal pumps or the number of strokes per minute for piston pumps;
e) nominal water temperature in front of the pump;
e) maximum head at rated flow.
After every major overhaul of the pump, a pump test should be carried out to determine the flow and head. The test results must be documented in an act.
The head created by the pump must supply the boiler with water at the operating pressure downstream of the boiler, taking into account the hydrostatic height and pressure losses in the boiler path, the regulating device and in the feed water path.
The characteristic of the pump must also ensure that there are no interruptions in the power supply to the boiler when the safety valves are triggered, taking into account the highest pressure increase when they are fully opened.
With group feeding of boilers, the pump head must be selected taking into account the above requirements, as well as based on the condition of supplying the boiler with the highest operating pressure or with the highest loss of head in the feed pipeline.
The supply of feeding devices should be determined by the nominal steam capacity of the boilers, taking into account the water consumption for continuous or periodic blowdown, for steam cooling, for reduction-cooling and cooling devices and for the possibility of water or steam loss.
The type, characteristics, number and circuit of the power supply devices must be selected by a specialized organization for the design of boiler rooms in order to ensure reliable and safe operation of the boiler in all modes, including emergency stops. It is allowed to operate boilers with a steam capacity of not more than 1 t / h with one feed pump with an electric drive, if the boilers are equipped with safety automatics, which excludes the possibility of lowering the water level and increasing the pressure above the permissible one.
A safety valve must be installed on the supply line between the shut-off element and a piston pump that does not have a safety valve and the generated head exceeds the design pressure of the pipeline.
For pumping slurry, we noticed that centrifugal pumps are limited in their capacity. Are there piston pumps used for pumping slurry?
Centrifugal pumps are better suited for pumping slurries and contaminated liquids.These pumps have large clearances and no valves, making them less susceptible to wear from suspended solids.
What is the most efficient way to reduce energy consumption in existing centrifugal pump installations?
Using variable frequency drives and eliminating gate valves for flow control are generally the most effective ways to reduce pump energy consumption. Even when the valves are wide open, this usually results in a significant waste of energy.
Frequency converters allow the pump speed to be adjusted to match the head required by the system. This reduction in speed is accompanied by a reduction in power, which contributes to a reduction in electricity consumption.
What is the atmospheric pressure for the pump?
This is the force that exerts pressure on a unit area by the weight of atmospheric pressure. At sea level and at a temperature of 15C, the standard atmospheric pressure is 14.7 p.s.i. or 750 mm Hg or 1013 m bar.
What is pump gauge pressure?
Taking atmospheric pressure as a starting point, gauge pressure is calculated by dividing the unit of force by the unit of area caused by the liquid (-750 Ng).
What is the absolute pressure of the pump?
This is the total pressure measured by dividing the unit of area by the unit of area caused by the fluid. It is equal to the sum of atmospheric and gauge pressure.
What is vacuum or pump suction pressure?
It is generally accepted that the pressure inside the pump is below atmospheric pressure. This pressure is usually measured by subtracting the measured pressure at the pump from the atmospheric pressure.
What is pump outlet pressure or pump discharge pressure?
This is the average pressure at the pump outlet during operation.
What is the pump inlet pressure?
This is the average pressure measured near the pump inlet during operation.
What is the differential pressure across the pump?
This is the difference in absolute pressure at the inlet and outlet of the pump during operation.
What is the density of a liquid?
The density of a liquid is its weight per unit volume, often expressed in pounds per cubic foot or grams per cubic centimeter. (The density of a liquid changes with temperature.)
What is saturated steam pressure?
The saturated vapor pressure of a liquid is equal to the absolute pressure (at a certain temperature) at which the liquid turns into vapor.Each type of liquid has its own saturated vapor pressure. This takes into account the temperature.
What is the viscosity index of the pump fluid?
The viscosity index of a fluid is a unit related to its ability to withstand a shear force. Substances with a high viscosity index require a greater shear force to shear fluids than substances with a lower viscosity index.
CENTIPOISE (cPo) is the most convenient unit for measuring the viscosity index.You can find out the absolute viscosity with a device such as a viscometer. It measures the force required to rotate a micrometer screw / roller / axis.
Other viscosity units such as the centistokes (cs) Salbolt Second Universal (SSU) are units of measure for the kinematic viscosity in which a specific gravity of the fluid affects the measured viscosity. Kinematic viscometers usually measure the force of gravity of a fluid flowing down a calibrated tube, taking into account the flow time.
Unfortunately, viscosity is not a constant, fixed property of a liquid. This characteristic changes depending on the density of the liquid and the type of pump.
In pump operation, a decrease in viscosity with increasing temperature is considered natural.
What is the effective viscosity for a pump?
Effective viscosity is the observation of the behavior of viscous fluids under the influence of shear forces. There are several types of behavior for viscous fluids:
Newtonian fluid: the viscosity remains constant as the flow rate or atmospheric pressure changes.
Newtonian liquids are water, mineral oils, syrups, hydrocarbons, resins.
Thixotropic liquids: Viscosity decreases with increasing flow rate or changing atmospheric pressure.
Thixotropic liquids are soap, asphalt bitumen, vegetable oils, glue, ink pastes, resins, varnishes, and some suspensions.
What is an NPSH pump?
A generally accepted term used to describe the required state of the pump inlet to a positive-flow (non-self-priming) pump.
We have NPSH = (P + ha * d) —tv-J
P: absolute pressure in liquid
ha: head of liquid at the pump inlet
ha <0 if the area occupied by the liquid is below the pump inlet
ha> 0 if the area occupied by the liquid is higher than the pump opening
d: density of liquid
J: input system loss
tv: saturated steam pressure
What is the required NPSH for a pump?
Required NPSH is a pump characteristic that indicates how much head pressure is required at the inlet to keep the pump running.The indicator varies depending on the change in pump speed and fluid viscosity. For satisfactory operation under a number of conditions, it is necessary that the existing NPSH value be greater than or equal to the required NPSH. When the absolute pressure of the liquid inside the pump falls below the saturated vapor pressure, the liquid will begin to turn into vapor, the so-called phenomenon of cavitation. In a positive displacement pump, cavitation occurs when the fluid velocity is insufficient to fill the pump cavity.
What is pump cavitation?
The result of inefficient pump operation, which can lead to pump failure, is accompanied by characteristic noise.
To avoid cavitation and to ensure that the existing NPSH is higher than the required NPSH, the following measures must be taken to ensure that the pump is supplied with fluid:
– reduce the speed of the pump (reduce the flow rate)
– increase the size of the inlet diameter
– reduce the length of the inlet pipeline.Change the number of fittings
– Increase pump size for a given flow, this decreases the required N.P.S.H.
The measures taken, taking into account the operating conditions of the pump, will ensure the supply of liquid to the pump and its filling, preventing cavitation.

Some pump instructions mention Newtonian fluid. What does Newtonian fluid mean?
Newtonian fluid (named after Isaac Newton) is a viscous fluid that obeys Newton’s law of viscous friction in its flow, that is, the tangential stress and velocity gradient are linearly dependent. The proportionality factor between these values is known as viscosity.
From the definition, in particular, it follows that the Newtonian fluid continues to flow, even if the external forces are very small, as long as they are not strictly zero. For example, water is a Newtonian fluid because it continues to exhibit the properties of a fluid regardless of the rate of stirring, as opposed to non-Newtonian fluids, the viscosity of which changes with the rate of flow of the fluid – for example, stirring can leave a “hole” behind (which is gradually filled with time – this behavior is observed in substances such as pudding, a suspension of starch in cold water and, in a less strict framework, sand), and with a decrease in the thickness of the liquid layer, a jump in viscosity occurs due to a change in the flow rate of the liquid (this is observed in some non-dripping paints which are easy to apply, but become very viscous on the surface immediately after application and do not run off even if the surface is vertical).
For a Newtonian fluid, viscosity, by definition, depends only on temperature and pressure (as well as on the chemical composition, if the fluid is not pure) and does not depend on the forces acting on it.
The pump in the well worked without interruption for 3 years, and suddenly it began to turn on and off frequently. The system works in jerks, and the automatic system clicks at the hydraulic tank all the time.
Obviously, the diaphragm in the hydroaccumulator (hydraulic tank) has torn. Its service life is 3-5 years (depending on water quality).Clicking – the pressure switch, constantly turning on and off the pump, because no water supply. The integrity of the diaphragm can be easily checked by pressing a sharp object on the accumulator nipple (as in a car wheel). If water comes out of the nipple, the membrane must be replaced. The cost of the membrane replacement service depends on the capacity and brand of the accumulator.
I was drilled a well of 23 meters. The water in it is only 4 meters from the bottom. I contacted different companies with the question of how to choose the optimal pump, they offer different pump options: they advise a baby pump for such a well, advise a water cannon, advise installing a German Grundfos pump.How to choose a pump?
To choose a pump, it is necessary to take into account the following: if the debit (productivity) of the well is very small, then the water must first be accumulated, and then pumped with a centrifugal pump into the water supply system. To accumulate water, a baby pump, a storage tank with a float switch, is suitable. And for automatic water supply – a pumping station with a hydraulic accumulator and automation.
What is vertical axial load and how does it occur?
Vertical axial load is the force acting vertically downward on the impeller and shaft assembly during pump operation, taken up by the lower thrust bearing of the electric motor.
Most pumps and electric motors are designed to operate under continuous vertical load conditions, but nevertheless very often it can create difficulties in the operation of the pump and the electric motor. Axial loading occurs when the pump is running at very low flow, which results in higher discharge pressures. Continuous operation in this range can damage the thrust bearing of the electric motor, and there can be problems with overheating of the electric motor and pump due to insufficient cooling by the fluid flow.To minimize thrust-related difficulties, the pump must be operated within a defined range of minimum and maximum flow rates.
For this reason, on the performance curves of Grundfos borehole pumps, the permissible flow range is marked with a solid line and the non-permissible operating range with a dashed line.
I need a submersible pump, the depth of the well is 9 meters, the pump is 1 cubic meter per hour. Please help me with choosing a pump.
1. Well debit.
2. Internal diameter of the casing.
3. Water mirror level.
What is the difference between the pumps “Malysh” and “Aquarius”?
“Kid” is a valve type pump, and “Aquarius” is a rotary one. “Malysh” is designed for well productivity up to 500 l / h. “Aquarius” – up to 1000 l / h
What is the difference between the GRUNDFOS and PEDROLLO pumps?
Grundfos pumps have built-in protection systems, Pedrollo does not.Pedrollo 4-inch pumps are not suitable for all types of wells. Grundfos pumps 3-inch – suitable for all types of wells.
Where is the best place to install the automation of water lifting equipment?
If the house has a free area of 1 m², then it is better in the house – it is more convenient for service.
Is it possible to temporarily install the “Kid” pump (for example, for repair work), and then more “serious” water-lifting equipment? For wells of what depth is this acceptable?
Pump “Kid” – up to 30 meters
What is the difference between a 2-line and 3-line submersible pump?
The difference between a “two-wire” and “three-wire” submersible pump is related to the type of single-phase electric motor used.A three-wire single-phase motor requires a control cabinet with a starting capacitor.
The starting capacitor is used to start the electric motor and is turned off after the electric motor has finished accelerating. Because of this starting device, there are three wires connected to the power supply (plus one wire for connecting to ground), hence the name “three-wire pump”. The two-wire motor does not require a control cabinet.
Instead of using a starting capacitor, the two-wire motor has an electrical device built into it, which is used to start the motor.Because of this, the starter only needs two wires connected to the power supply (plus one wire for connecting to ground), hence the name “two-wire pump”.
Typically, a 3-wire motor will have slightly more starting torque than a 2-wire motor (although no additional starting torque is needed in most applications), however, a 2-wire motor will tend to be installed and wired somewhat easier and with less costs.
Can the pump run dry?
Running the pump dry can damage the mechanical shaft seal and the motor. Float switches (level sensors) installed in your hydraulic system must be set to maintain the minimum water level required to operate the pump.
Before using the pump, be sure to check that the selected application of your pump complies with our instructions in the technical data sheet and in the “Installation and operating instructions” for the pump.
What is the maximum allowable temperature of the pumped liquid?
The maximum permissible operating temperature of a sump, sewage or mud pump determines whether the pump can be continuously operated in the fully submerged position or must be operated intermittently. For information, please refer to the Installation and Operating Instructions for your pump.
My discharge line continues to clog, why?
The blockage can be attributed to one of two causes.First, is the pumping speed through the pipeline correctly calculated? If the pump speed is not correctly selected for pumping solids-laden slurry, the slurry particles can settle at the bottom of the pipeline and clog it over time. Second, is the piping size selected for the pumped slurry? Depending on the amount of solids being pumped, an oversized pipe must be selected to ensure that all slurry flows through the pipe.
Can the pump be used to pump sea water?
In the world, submersible drainage pumps have been used for pumping sea water for a long time.However, if the pumps are made of a light material such as aluminum, their lifespan for pumping seawater is severely limited. Zinc anodes will help extend the pump life (zinc anodes protect the pump from galvanic corrosion), but these should be checked and replaced regularly. Alternatively, Grindex offers a line of drainage and slurry pumps made from 316 SS, which is resistant to the negative effects of seawater.
Is the air valve really working?
All Grindex pumps are equipped with an air valve. The air valve is necessary so that in the case of the pump running “dry”, it does not overheat, cooling with the help of the air flow. An air valve is a simple mechanical device that remains closed by the pressure of the pumped liquid. For example, when the sump containing the pump is emptied, the water pressure drops and the spring is released, thereby opening the valve.This allows the pump impeller to operate in the same way as an IP55 fan. The pump motor blows air around and blows out through the valve to the outside. The pumps can operate in this mode for several hours without harm. Then, when water begins to flow into the sump again, the water pressure that builds up around the pump housing closes the air valve and the pump starts operating normally. An air valve demonstration was held at one of the exhibitions. The Minex 220V pump was turned on to work for the whole day under the light of lights and the pump did not fail.Continuing to work as a demo to this day.
How often should the submersible pump be routinely serviced?
Manufacturers always indicate the recommended service interval. In the case of Grindex pumps, this interval is about 2000 hours of operation, while the manufacturer recommends no more than 500 hours for Japanese Toyo pumps between the previous and next service. Why such difference?
The answer is that the service interval should be related to the time spent by the pump in its working condition.Therefore, a Grindex pump, such as Major N, operating in an environment where the water is clean and non-corrosive, should run for at least 2000 hours without creating any problems for the owner. And the Toya pump, operating in its normal environment, such as scale, which is highly abrasive and corrosive, requires much more frequent servicing.
The service intervals for pumps are comparable to those for automobiles, if neglected, the risk of serious damage to the pump increases.
Can Grindex submersible pumps be used in tandem?
Yes, Grindex pumps can be used for sequential operation. There are no specific pump lines. Several conventional drainage pumps can be connected in a so-called “tandem connection”. A special flange is installed at the bottom of the pump to connect the pressure hose of the previous pump. This is very effective in situations where it is necessary to significantly increase the flow of the pumped liquid while maintaining the IP68 standard for the electrical equipment used.This is especially useful in many underground jobs, such as in mines or tunnel construction, where water must be pumped over long distances and the likelihood of flooding is very high. Converting the tandem connection to the standard configuration is straightforward, so that later these pumps can be used for their standard application.
What is meant by sludge?
Sludge (from it. Schlamm – mud) – waste in the engineering development of a mining product, constituting dust and its smallest parts, obtained in the form of sediment when washing any ore material.
Sludge can also be:
• Powdery substance, usually containing precious metals, precipitated during the electrolysis of copper, zinc and other metals.
• Insoluble deposits in steam boilers in the form of sludge and solid sludge. To remove sludge, the boiler is blown through or thermosiphon sludge removal is carried out.
• Sludge from coal or ore in wet dressing.
• Sediment in the form of fine particles formed during settling or filtration of a liquid.
• Product of wet milling of quartz sand – sand sludge.
• Drilled rock carried by drilling fluid from the bottom of the well to the day surface.
• Waste from grinding on metal-working grinding machines, consisting of small (up to 1 micron) metal shavings, abrasive material of grinding tools and emulsion, if used as a coolant (cutting fluid). It usually gets into the drainage system of the coolant of the machine and requires periodic removal.
Pumped sludge in its simplest form can be divided into three types; light, medium, and heavy. Below are rough indications of these types.
Presence of solid particles mostly random
Particle size typically <200 microns
Type of sludge – non-settling
Specific gravity of suspended matter <1.05
Less than 5% solids in total mass
Particle size from 200 microns to 5 mm
Type of sludge – non-settling and settling
Specific gravity of suspended matter <1.15
5% to 20% solids in total mass
The main composition of the pumped sludge is sand or gravel
Particles> 5 mm
Type of sludge – non-settling and settling
Specific gravity of suspended matter> 1.15
More than 20% solids in total mass
