Structural Characteristics of Submersible Crossflow Pump
1, Impeller
Impeller is based on the most advanced hydraulic model with good ,steady,mature performance.Much lower nD value is chosen with better anti-cavitation to make sure stead operation.
2, Shaft seal
Two sets of separate mechanical seals are used to ensure the safety and reliability of sealing.
3, Monitoring device
Submersible crossflow pump has several protection devices which lead the leading wire to electric control cabinet,and the protection devices are:stator temperature protection,protection of bearing temperature rise ,protection of motor water inlet,protection of oil cavity temperature rise .
4,Pump/motor shaft
Pump and motor are concentric with compact structure,and the shaft extension is shortened as much as possible,and the rigidity is improved.Deflection is controlled within the allowable range based on the design,and the vibration is lower when operating.Service life of sealing and bearing is much longer.
5, Flow passage
CFD and experimental method are combined to confirm the flow line shape to ensure high efficiency when operating.
6,Cooling
Motor casing passes the heat into the surrounding medium,and the heat is taken away by the surrounding water.High power high voltage motor uses inner air passage heat dissipation technology,which makes three-phase winding temperature rise lower with an even temperature field distribution.
7,Motor
High performance squirrel cage induction motor is specially designed for submersible pump according to GB/T755 standard.Thermal classification is F,and 380V,660V,6KV,10KV etc. voltage classes are used.Two VPI insulation processes are used to ensure the reliable insulation of motor.
8,Bearing
As for horizontal structure,large common structure finite element analysis software is used to analyze rotating components dynamically,researching its deflection,vibration,inner stress,support counter-force,characteristic frequency.And the design of structure,bearing arrangement,bearing choosing are all based on this foundation.Rolling bearing is used to bear all the axial and radial loading,totally separated from the transported medium.

- Q:Dear friends, please let me know in most of the power plants recirculation line and balance leak off lines are provided for boiler feed water pumps and those lines are connected to Deaerator. Why?
- The feed pumps for most power plants are multistage centrifugal pumps. They have a minimum flow requirement or the balancing forces of the various impellers are lost and the pump is damaged. A recirculation line permits a minimum flow to be maintained at all times. It goes back to the deaerator so the boiler feedwater is not lost. Note: many of these pumps have the recycle automated so it is only in operation at very low flow rates. The leak off from the balancing line is recycled for the same reason.
- Q:The pump works and water goes to the house from the reserve tanks but there can be long delays before it cuts in after mains pressure is lost. After it stops the pressure gauge falls back slowly to zero. Pressure vessel is a sphere has a valve on top. Any suggestions ?
- Sorry I don't know the Espa make but the theory is the same...if the pressure falls once the pump stops,that sounds like a leak in the lines somewhere (most probably the foot valve needs repacement.the fact that the pressure falls to 0 lbs would mean either that the pressure switch is not set properly or it also needs replacement.normal settings for household systems are either cut in at 20lb cut out at 40lbs or cut in at 30lbs and cut out at 50lbs.Check your pressure tank if its got a bladder it should be pressurized to 2lbs below cut in pressure this should be done with the pump off and no water pressure.IF your tank is a non bladder model empty it completly and then prime and restart the pump.
- Q:The garage told me my water pump was pumping quot;weaklyand needs to be replaced.
- Good question (finally). It will pump weakly if it is not turning fast enough or is leaking at a seal. If you have a faulty belt that is slipping it will not turn fast enough. Go to another mechanic.
- Q:we live in the country in the warm months and have a portable pump that takes water from a 15 foot deep well. It feeds water to a toilet and a hot water tank mostly and a sink and shower and washer. We put the pump outside the bathroom and need to know how to start it, thanks!
- Make sure the foot valve is working. Fill the pump and the suction hose with water. Start the pump. It should pic-up and pump. Its very important that the foot valve holds when the pump shuts down. Good luck
- Q:no water is running my deep well pump kicks on every 15 min. it runs for 1-2 min when it kicks off then a noise like someone threw a ball against the house. can you help
- Where is the noise coming from? The pipes, pressure tank, or starter box. I assume you have a submersible pump? If it is the starter box it could possibly be that your pump may be at fault pulling to much amperage and causing the starter box to make those kind of noises when it cuts out. Well pumps typically last for 15 to 20 years with the odd exception. Another thing to check is your pressure tank. If it is one of those old galvanized ones it needs to be charged with air regularly as they tend to become water logged giving you very little water in between pump cycles. Another thing you could try is cleaning the points with some emery on the pressure switch. They tend to become corroded and can cause problems with the pump operating at all.
- Q:I need a water pump gasket for my mustang water pump.What can I use if I have no gasket material?
- I wouldn't use anything except what was required for that pump installation because I wouldn't want to have to go back and do the whole job a second time if the pump leaks around the gasket area. A new gasket should come with a new pump. If not go back to a quality auto parts store and get a gasket. I'm not sure I'd trust the squeeze on gasket silicone in place of a gasket and I'd get Permatex gasket sealer to use with the new gasket on all surfaces before I reinstalled the pump. It's worth taking your time to do it right. Make sure there's no antifreeze coolant oozing onto the metal sealing surfaces, because the gasket won't seal unless the surfaces are clean and dry (been there, done that).
- Q:How does a pump get water from a low low elevation to a higher elevation.
- The simplest form of water pump is a plastic spiral where the outermost spiral dips under the water and out as it rotates. The spiral can be driven by attached paddles if the water is flowing. As the water progresses down smaller spirals the pressure increases. The water exits through a rotating coupling at the centre of the spiral. A single stage pump can only raise water 15 feet (1 atmosphere) A windmill is a good example of a simple pump where a lever moves up and down, A valve closes at the bottom of a tube on the up stroke and raises the water by the length of the stroke. This water opens a second valve near the top of the tube as soon as the upstroke starts and the water is pushed up. This pump does not work by creating a vacuum. On the downstroke the upper valve closes due to the raised water pushing on it, and also due to its own weight, and the lower valve opens from the water below pushing on it as the cylinder descends. At the end of the downstroke the valve closes under its own weight and the weight of the water above it and the cycle repeats To raise water higher than 15 feet using a windmill, it is necessary to install a small tank at, say 14 feet, with a second lower and upper valve in a tube. The first stage pump fills the tank which the second stage pump then lifts another 15 feet, This process can be repeated until the water reaches the surface, but a bigger windmill will be needed to power multiple pumps
- Q:How much should I look for paying for my 1998 Honda Accord Water Pump??? With Labor and Materials?
- Do it yourself and save $600. It's not that hard and it'll be a learning experience. If you have any friends that know how to work on cars ask them to help.
- Q:How do I change the water pump in my 1998 ford mustang manual v6?
- If you don't already know how to do it, then take it to a shop to have it done by the professionals. If you insist on trying it yourself, buy a Chilton's manual for your car, do some online research (with pictures), and buckle down. You will need to loosen the belts, remove the belts, remove the water pump, replace it, and reinstall everything. You will need to make sure that the belt is routed the correct way, or BOOM! You might also want to replace the timing belt while you're in there. It makes sense to replace it if you already are removing it, and the timing belt is something you can't afford to have go bad on you.
- Q:55KW motor driven lift 70M, the displacement of 180 cubic meters per hour of water pump, the configuration should be no problem, but after the start of the current to 170A (rated 100A), off a small valve to the current export half to reach the rated current. Why current will close a small valve instead of small? Will close a small valve will not affect traffic flow can be? To the 180 party?
- 170A has shown that the motor is overloaded; the head 70M; the displacement of 180 cubic meters; the approximate power is 42Kw (efficiency is higher). At this point, the current of the corresponding motor should be approximately 86A;The power of water pump is related to the quantity of water transported. The water pump is a passive energy conversion device, and it has no regulating ability. It depends entirely on the intersection of its pipeline characteristics and its own characteristics,No, your situation is the pump and pipeline characteristic, the pump head is higher than the resistance of pipeline, so that the water flow movement (increase too large). Pump power becomes largerShut down the water pump, the valve will certainly reduce the amount of water, as for whether to reach 180, you can see the pressure gauge to show the pump lift to determine the pressure of less than 70 meters, the flow of more than 180
