1 QJ series submersible pumps for Wells, by diving three-phase asynchronous motor and pump consists of two major parts. Motors with the upper part of the pump body, the upper end of the motor shaft with reliable sealing system, can effectively prevent the motor coolant Exchange with the pumped medium, ensure the pump can run safely and reliably for a long time.
2, submersible pump for vertical single-suction multistage centrifugal pump submersible motors are water-filled submersible induction motor, vertical wells. Motor and pump through the tube coupling directly.
3, motor windings for the Nylon Sheath polyethylene water resistant magnet wire. Motor cavity can be filled with clean water.
4, water lubricated bearings motor bearing. There was no motor can withstand the pump axial thrust bearing, high lift pump thrust bearings containing nickel and copper sectors, and it is imported for grinding feilebosi skateboard, bearing axial pumps up and down force.
5, holding high the Cheng Qian pump pumps and motors additional axial loading, head to 900m.
