A high-lift centrifugal pump can be adapted to low-lift conditions, but it cannot be directly put into use; otherwise, it is prone to equipment failure and increased energy consumption. In daily operation, parameters can be adjusted through four methods: throttling, frequency conversion, cutting the impeller, and bypass return. By selecting an appropriate plan based on the actual head conditions, stable operation can be ensured.

Keep a detailed record of the cleaning and treatment process, including the cleaning agent used, the type and amount of disinfectant, the amount of liquid discharged and the treatment method, the amount of dirt collected and the treatment method. These records facilitate subsequent traceability and management.

Submersible sewage pump power supply voltage is too low because the power supply voltage is too low, resulting in the submersible sewage pump can not start, the submersible sewage pump is usually required to 380V power supply voltage, should be adjusted to more than 342V. When the submersible sewage pump is used in the emergency situation of flood prevention and drainage, and the power supply voltage is lower than 342V.
