QJ type deep well submersible pumps, also known as QJ-type wells with submersible pumps, according to the national standard design of energy-saving products, widely used for irrigation, industrial and mining supply and plateaus, mountains of human, animal water. The pump consists of QJ submersible pumps and submersible motors consisting of one submerged work. Has a simple structure, small size, light weight, installation, easy maintenance, safe, reliable and efficient energy-saving features. QJ type deep well submersible centrifugal pump, using water-lubricated bearings, couplings rigidly connected in the motor driven pump impeller centrifugal force produced by the rotation of the motor and the coupling using the liquid through the pump housing to increase energy diversion does not have a check valve . Before use must be accountable within QJ type deep well submersible pump clean water filled, tighten water, bleed screws, or can not be used. Pump using real body completely submerged, but not more than 70 meters diving depth effects were carrying water. Top with a check valve in the pump, the pump is shut down to prevent water damage due to water pipe in the working parts back in. There scuppers can slowly let go of the pipe in the water to prevent freezing in winter pipeline valve. But the low lift.
