Well with submersible pump unit installation: 1. Submersible pump device by the pump, motor, water pipe, waterproof cable and control switch composed of five parts, the pump is a single suction multi-stage vertical centrifugal pump. 2. Submersible motor adopts flush wet structure, cavity filled with water, mainly used for motor cooling, and bearing lubrication. In the course of operation due to temperature changes, causing the motor cavity flushing pressure changes, the lower end of the motor voltage regulator can be automatically adjusted. 3. In order to prevent mud intrusion into the motor, the top of the motor equipped with a rejection of sand and skeleton oil seal, formed a sand control mechanism, the entire motor seal structure. 4. The upper end of the motor is provided with a water injection hole and a vent hole, and the lower end is provided with a water discharge hole. 5. The lower part of the motor is equipped with a thrust bearing grade thrust plate, mainly to withstand the residual axial force of the pump and the weight of the motor rotor. 6. Motor stator winding using water-resistant wire, a good insulation and water resistance, the rotor cage structure.
