The deep well pump is mainly composed of three parts: the top part is the electric motor, the middle part is the water supply pipe and the lower end of the transmission shaft is the working part of the deep well pump, which is submerged below the well surface.
Deep well pumps can be divided into segmented multi-stage vertical centrifugal pumps. According to the structural characteristics of deep well pumps, correct use and timely troubleshooting are crucial for ensuring the safe operation of deep well pumps and extending their service life.
Before starting the deep well pump, the suction pipe and pump must be filled with liquid. After turning on the pump, the impeller rotates at high speed, and the liquid inside rotates together with the blades. Under the action of centrifugal force, it flies away from the impeller and is ejected outward. The ejected liquid gradually slows down in the diffusion chamber of the pump casing, increases in pressure, and then flows out from the pump outlet and discharge pipe.
At this time, a vacuum low-pressure zone is formed at the center of the blade due to the liquid being thrown towards the surroundings, which has neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of atmospheric pressure on the pool surface. The liquid is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.
