​What are some of the knowledge about deep well pumps?

The most important feature of the deep well pump is the integration of the motor and the pump. It is a pump that is immersed in a groundwater well for pumping and transporting water. It is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Since the motor is submerged in water at the same time, the structural requirements for the motor are special compared to the general motor. The structure of the motor is divided into dry, semi-dry, oil-filled and wet.

The suction tube and pump must be filled with liquid before the pump is turned on. open

After the deep well pump, the impeller rotates at a high speed, and the liquid rotates with the blades. Under the action of centrifugal force, it flies outward from the impeller, and the liquid that is ejected in the pump chamber diffuses slowly, the pressure gradually increases, and then the pump At the exit, the discharge pipe flows out. At this time, at the center of the blade, the liquid is drawn to the surroundings to form a vacuum low-pressure zone with neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure of the pool surface, and the liquid is continuous. It is continuously sucked from the liquid pool and continuously flows out from the discharge pipe.
