1. QJ series submersible electric pump, submersible three-phase asynchronous motor and pump two parts. Motor and the upper part of the pump body straight league the upper end of the motor shaft with reliable seal device, can effectively prevent the exchange between the motor and the coolant pumping medium, to ensure the long-term safe and reliable operation of the pump.
2. Submersible pump for single suction multi-stage vertical centrifugal pump, submersible motor for water filled wet, vertical wells with submersible asynchronous motor. The motor and the water pump are connected directly through the tubular coupling.
3. The motor winding is nylon sheath polyethylene water resistance electromagnetic wire. The motor chamber is filled with clean water.
4. Motor guide bearing with water lubricated bearings. Motor lower was not able to sustain the pump axial force of the thrust bearing, high lift pump thrust bearing with nickel copper segment, and it of the grinding is imported the FILA Perth skateboard, bear the axial force of pump.
5. High lift submersible pump in the pump and motor center additional axial force carrier, head can be increased to 900m.
