Selection and use of submersible pump precautions
Feb 28,2025
in the process of selection and use of submersible pumps, the submersible pump should be correctly selected according to its own working conditions, when selecting the submersible pump, the flow, head and installation method should be considered, only when the selected head is close to the actual required head, the pump can be operated energy-saving, and improper selection will have a great impact on the operation of the pump.
reduce the flow rate of the pump does not rise and does not drain, improve the rise of the submersible pump when working, the mechanical friction is large, the submersible pump is damaged, the flow is too large, the motor is overloaded, the operation is long-term, the winding temperature rises, the insulation layer is aging, and the motor burns out.
many users usually think that they should choose a pump with a much higher head than the actual working conditions when choosing a submersible pump, but this idea is wrong.
If the head difference between the selected pump and the actual working condition is more than 10 meters, it will lead to excessive flow of the submersible pump, and the pump motor will be current for a long time, which will easily cause the motor to burn out.
