How the submersible pump works.

The submersible pump is generally composed of pump body, lift pipe, pump seat, submersible motor and starting protection device.Colloquially speaking, a pump and a motor are combined to transport the liquid.
The mechanical structure of the body is simple in structure and easy to use.
According to the relative position of pump and motor, the submersible pump can be divided into upper pump and lower pump type.The upper pump submersible pump is mounted on top and the motor is below, this structure.
It greatly reduces the radial dimension of the pump, so it is mainly used for submersible electric pump and small operation submersible pump.The lower pump submersible pump motor is above, the pump is below, it is divided again.
For both internal and external.The liquid pumped in the pump submersible pump is first used to cool the motor and then pump out of the pump by encircling the ring flow of the motor.
My mouth.
Even if the pump is close to draining the pool, there is no need to worry about the heating of the motor, so the application scope is expanding.The pump submersible pump is directly from.
After the impeller, the pressure water chamber or the outlet of the guide vane discharge the liquid, the motor is also pumped liquid cooling.Because the lower pump structure can work in the lighter fluid,
Therefore, it is used for operating surface submersible electric pump, especially it is the main structural type of large diameter submersible pump.The mechanical seal of the pump submersible pump is located in the high pressure zone of the outlet flow.
The higher the lift, the higher the water pressure here, so the mechanical seal performance is controlled by the lift.
