Structural characteristics of stainless steel submersible pump

Structural characteristics of stainless steel submersible pump

1. It is composed of two parts: submersible three-phase asynchronous motor and water pump. The motor is directly connected to the upper pump body, and the upper end of the motor shaft is provided with a solid shaft seal device, which can effectively avoid the exchange between the coolant in the motor and the pumped medium, and ensure the long-term safe and reliable operation of the water pump.

2. The submersible pump is a single-suction multistage vertical centrifugal pump; the submersible motor is a water-filled wet, vertical well submersible asynchronous motor. The motor and the water pump are directly connected through a barrel coupling.

3. The motor winding is nylon sheathed polyethylene water-resistant electromagnetic wire. The motor cavity can be filled with clean water.

4. The motor guide bearing adopts water lubricated bearing. The lower part of the motor is equipped with a thrust bearing that can withstand the upper and lower axial forces of the water pump. The thrust bearing of the high-lift water pump uses a nickel-containing copper sector block, and it is an imported Philebs sliding plate that can withstand the upper and lower axial forces of the water pump.

5. The submersible pump is equipped with an axial force carrier between the pump and the motor, and the lift can be increased to 900m.
