What should I do when the sewage pump fails? We need to understand the common maintenance failures of sewage pumps. 1. The power supply voltage is too low a. Transformer output voltage is low Solution: adjust the transformer voltage b. The cross-section of the power supply line is too small Solution: use a line with a larger cross-section c. The power supply line is too long. Treatment method: move closer to the transformer 2. The voltage drop of the power cable is too large a. The cable is too long. Treatment method: cut off the excess part b. The cross ... Read More

The commonly used blanks for machining are castings, forgings, profiles and welded parts. Different types of blanks and the accuracy, roughness and hardness of the blanks have a direct impact on the machining process. The following factors should be considered when selecting a pump blank: (1) The material of the part and the requirements for the organization and performance of the material. The material of the part specified on the design drawing generally determines the type of blank. For example, if the part material is cast iron, the casting method must be used to make the blank. For steel parts, ... Read More

The difference between sewage pump and submersible pump Sewage pumps are generally driven by motors, which are relatively resistant to voltage shocks. Submersible pumps are quick-open and quick-close, and are generally used in places with small flow and small pressure, where the switching frequency is required to be large, and vice versa. The opening of the sewage pump valve can be controlled, and the state is open, closed, half-open and half-closed, which can control the flow of the medium in the pipeline, but the submersible pump cannot meet this requirement. The following is a brief introduction to the difference between ... Read More
