The purpose of installing a diversion protective cover on a submersible pump for general wells is to accelerate water flow and remove heat from the surface of the motor.
The QJ submersible pump itself is a submersible pump used in deep wells. The upper part is the pump head, the lower part is the motor, and the middle part is the water inlet. When the pump is running, water quickly flows to the water inlet through the gap between the motor and the wellbore pipe. During this process, some of the heat on the surface of the motor is taken away by the water flow, thereby improving the service life of the motor.
What kind of environment does it require to install a backflow protection cover
1. If the diameter of the well is too wide, the liquid flowing through the surface of the motor cannot reach the minimum flow rate specified by the motor, and a guide cover needs to be installed.
2. If the upper water supply well is for upper water supply, the motor cannot be cooled and a guide cover needs to be installed.
3. If the water pump is installed in a water tank or open water area, a diversion cover needs to be installed.
