Introduction: submersible pump (or electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps.

 

Applications:

Submersible pumps are found in many applications. Single stage pumps are used for drainage, sewage pumping, general industrial pumping and slurry pumping. They are also popular with aquarium filters. Multiple stage submersible pumps are typically lowered down a borehole and used for water abstraction, water wells and in oil wells.

Special attention to the type of ESP is required when using certain types of liquids. ESP's commonly used on board naval vessels cannot be used to dewater contaminated flooded spaces. These use a 440 volt A/C motor that operates a small centrifugal pump. It can also be used out of the water, taking suction with a 2-1/2 inch non-collapsible hose. The pumped liquid is circulated around the motor for cooling purposes. There is a possibility that the gasoline will leak into the pump causing a fire or destroying the pump, so hot water and flammable liquids should be avoided.

Q:Pump performance parameters have three sets of data, how to understand the flow, lift, flow speed
The middle parameter is the rated value. The lower limit is the maximum. General use of valve control.
Q:4--6 inch deep well pump head? How much per hour out of water?.
Deep well pump head is based on how much the impeller, impeller 200QJ section is 11 meters lift, 250QJ is about 17 meters, 300 meters high lift, 4 inch flow in 80 to 100 tons per hour, 6 inch flow in 150 to 200 tons per hour
Q:2 inches of water pump is generally equipped with high-power motors
3KW2 pole asynchronous motor
Q:Water pump eliminates air
First of all, why should exhaust air, pump suction principle is the rotation of the impeller, pump water inside the throw out, and then let the inlet pipe into a vacuum. Then, under the influence of atmospheric pressure, the water pressure is pumped into the pump. Therefore, if the water is not filled, the sealing of the pump is impossible to pump the air inside the evacuation of high vacuum. In other words, do not fill the water, you can not smoke water. You can hear the noise in the pump when the water bubbles under the bottom vacuumThe water doesn't go up because it doesn't have enough vacuum!The reason 1 is because there is no water filling,2, because your pump and water vertical height higher than the pump itself suction stroke.3., the pipeline resistance is too large (including the pipe diameter is too small, elbow and so on)
Q:What will the water pump reversal situation?
Reversal will also water out, but the amount of water is small, belong to "pressure water" effect, as if a basin of water, we do not shoot outward and down, the water will be out of the basin.
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
0 degrees water turns into a mixture of ice water. Do you think the water pump will work properly?
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
Water pumps are generally centrifugal pumpsThe circulation pump depends on what kind of liquid it is circulatingGrease is generally gear pumps
Q:Fire hydrant and fire pump adapter difference
Fire hydrant is out of water, the water pump is water supply to the pipe network
Q:Pump flow 6M3/H is an hour, how many tons of water?
1.5KW pump if the head 90 meters, then the flow of 2 tons, more than the most
Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Low inlet and outlet
