1. It consists of two parts: three -phase asynchronous motor and pump pump. The electric motor and the upper pump are connected straight, and the upper end of the motor is equipped with a reliable axis device, which can effectively prevent the exchange between the coolant in the motor and the pumping medium, and ensure that the pump is running safely and reliable for a long time.

   2. The submersible pump is a single -level multi -level vertical centrifugal pump; the submersible motor is a water -filled wet type, and the vertical well uses a diving asynchronous motor. The motor and the pump are connected through a barrel -type shaft.

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

   4. The motor bearing uses water lubrication bearing. The lower part of the motor has a stop bearing that can withstand the upper and lower axis power of the pump. The stop bearing bearing of the high -rise water pump uses nickel -containing copper fan -shaped blocks. Better.

   5. The submersible pump adds axial force bearer in the middle of the pump and the motor, which can be increased to 900m.
