The working principle of deep well water pump

Deep well water pump working principle:
WeiHu deep well water pump working principle is from the wells in the water pump, long shaft deep well pump is a relatively widely used in a pump, generally used for the well. Deep well pump is mainly composed of three parts: the top of the motor, installed in the middle of the wellhead is the middle of the water pipe and drive shaft for the deep part of the pump part of the work, submerged in the well water below. Due to well depth, requiring a larger head, long shaft deep well pump head range is generally 15 ~ 17 m. Deep well pump can be divided into segmented multi-stage vertical centrifugal pump. According to the structural characteristics of deep well pump, the correct use and timely troubleshooting, to ensure the safe operation of deep well pump to extend its service life is essential.
Weihu deep well pump before pump, suction pipe and pump must be filled with liquid. After the pump is pumped, the impeller rotates at high speed, and the liquid rotates with the blade. Under the action of centrifugal force, it leaves the impeller outward and the liquid is gradually slowed down and the pressure gradually increases from the pump Export, discharge pipe outflow. At this point, at the center of the blade at the center of the liquid is thrown to the surrounding and the formation of both no air and no liquid vacuum low pressure area, liquid pool in the pool of atmospheric pressure under the action of the suction pipe into the pump, the liquid is so continuous Constantly being sucked up from the liquid pool and continuously flowing out of the discharge pipe.
