6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100M, after the start to observe the voltage and current, check the motor winding insulation, whether in line with the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature.

 Structure brief introduction: the pump part is mainly composed of pump shaft, impeller, diversion shell, rubber bearing, check valve body (optional parts) and other components. The motor part is mainly composed of base, pressure regulating film, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand ring, water inlet section, and cable.

Isi njirimara ngwaahịa a gụnyere:

1.The motor is a water-loaded wet submersible three-phase asynchronous motor,and the motor cavity is filled with clean water for cooling the motor and lubricating the bearing.The regulating diaphragm at the bottom of the motor is used to adjust the expansion and contraction pressure difference inside and outside the body caused by the temperature rise of the motor.
2.In order to prevent the sand particles in the well water from entering the motor,two oil seals are installed at the extension end of the motor shaft,and the sand ring is installed to form a sand prevention structure.
3.In order to prevent the pump shaft from jumping when starting,the pump shaft is connected with the motor shaft through a coupling,and the thrust bearing is installed at the bottom of the motor.
4.The lubrication of the motor and the pump bearing is water lubrication.
5.The stator winding of the motor adopts high-quality submersible motor winding wire,with excellent insulation performance.
6.The pump is designed by computer CAD,with simple structure and excellent technical performance.
