QJ Deep Well Pump Construction&Features

· Compact vertical centrifugal multi-stage design with perfect standardization and generalization,easy operation and convenient maintenance.

· A complete electric submersible pump includes a water pump set ,electric motor ,a discharge piping,water-proof cable and a control panel.

· Submersible motor filled with clean water for cooling and lubrication,And the pressure regulation switch,located at the bottom of motor,shall automatically operate to balance the pressure fluctuation caused by temperature variations.

· A sand slinger and oil-sealed skeleton are equipped at the upper part of motor to form a  closed operating system for the motor ,thus preventint  any sand to penetrate into the motor.

· Water injection holes as well as air release hole are designed at the upper part of the motor,and water release hole at bottom(lower) part.

· Thrust bearing and collar are designed at lower part of motor to stand the weight of the squirrel caged rotor and the axial thrust residual.

· Water -proof electromagnetic wiring for stator with excellent insulation.
