Structure Characteristics of Deep Well Submersible Pump

Deep well submersible pump is a motor and pump directly into one of the water into the water work tools
    1, QJ series deep well submersible pump, by the submersible three-phase asynchronous motor and pump the two major components. The motor is connected with the pump body of the upper part. The shaft of the motor shaft has a reliable shaft sealing device, which can effectively prevent the exchange between the coolant and the medium in the motor and ensure the safe and reliable operation of the pump.
    2, submersible pumps for single-suction multi-stage vertical centrifugal pump; submersible motor for the wet, vertical wells with submersible motors. The motor and the pump are connected directly through the barrel coupling.
    3, the motor winding for the nylon sheath of polyethylene water resistant magnet wire. The motor cavity filled with clean water can be.
    4, the motor bearing bearings using water lubricated bearings. The lower part of the motor can not withstand the pump up and down the axial force of the thrust bearing, high-lift pump thrust bearing with nickel-copper fan-shaped block, and it is the mill is imported Philip skateboard, to withstand the pump up and down axial force The
    5, high-lift submersible pumps in the middle of the pump and motor additional axial load bearing, head can be increased to 900m.
