Working Principle

QJ Deep Well Submersible Pump Structure feature and work principle

QJ model submersible electric pump lifts water with high efficiency. Its pump head and motor are integrated, saving energy. It works under water, composed of submersible motor, pump head, lifting pipe, etc. It uses vertical water filling wet squirrel cage three-phase asynchronous motor. The motor is filled with clean water inside for cooling and lubricating the bearing. The motor winding uses polyethylene insulation nylon sleeve and water-resistant magnet wire. The top part of the motor is sealed with deflector and framework oil, preventing medium leakage inside or outside. The pump is vertical type, with single stage/multistage closed centrifugal impeller. It delivers medium via blower inlet casing.
