Well submersible pump works principle

Submersible pump is generally composed of pump body, Yang pipes, pumps, submersible motor and starter protection device. Popular speaking is a kind of fluid conveying machinery incorporated in the pump and motor, it has simple structure, easy to use.

According to the relative position of the pump and motor, submersible pump can be divided into the pump and the pump again. On the pump submersible pump in the above, the motor in the following, the radial size of this structure is greatly reduced the pump, so much for submersible electric pump Wells with submersible pumps and small homework. Submersible pump motor in the above, under the pump in the following, it is divided into inside and outside outfit type two kinds. Under the built-in pump submersible electric pump is conveying liquid first through the annular flow, surrounded by motor cooling pump export motor after outflow. Even in close to the pump drain suction tank, also don't have to worry about motor to heat up, so the application range is expanding. Outside hold pump submersible electric pump is directly from the pressurized water chamber or guide vane impeller body outlet discharge liquid, motor has been pumping the liquid cooling. Due to the structure of pump can work in shallow liquid, reason often used in the operation of submersible pumps, especially it is the main structural type of large diameter submersible pumps. Under pump submersible electric pump mechanical seal is located in the export of high water, the higher the lift, the water pressure is higher, so the performance of the mechanical seal is controlled by head.
