Comprehensive understanding of deep well pump

Deep well pump is the biggest feature of the motor and pump into one, it is immersed in the groundwater wells for pumping and transportation of water pump, is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage and sewage treatment. As the motor into the water at the same time, so the structure of the motor than the general requirements of the special motor. The structure of the motor is divided into dry, semi-dry, oil-filled, wet four.
Before opening the pump, the suction tube and the pump must be filled with liquid.
After the pump is pumped, the impeller rotates at a high speed, and the liquid rotates with the blade. Under the action of centrifugal force, the impeller flew out of the impeller, and the injected liquid gradually slows down and the pressure gradually increases. Outlet, discharge pipe out. At this point, because the liquid at the center of the blade is shaken to the surrounding and the formation of neither air nor liquid vacuum low pressure area, liquid in the pool of liquid under the action of atmospheric pressure, the suction pipe into the pump, the liquid is so continuous Continuously from the liquid pool was sucked up and out continuously from the discharge pipe.
The basic parameters of deep well pump: including flow, head, pump speed, matching power, rated current, efficiency, outlet diameter and so on.
