Due to its simple installation, small area, small maintenance, convenient maintenance, noise, etc., the mobile sewage pump is widely used in sewage discharge of municipal engineering, factories, commerce, hospitals, hotels, residential areas. At present, China's domestic mobile sewage pumps are mainly produced and manufactured by domestic manufacturers, and a small number of products are imported from abroad. The market prospects are very broad. However, because the reliability of diving sewage pumps needs to be strengthened, improving the technical content of its products is the main direction of manufacturers' future development.

Existing problems:

The pump is a vertical layout, the pump and the motor coaxial axis, so that the weight of the rotor part is the same as the water pressure direction of the impeller bearing; second, the pump is used under the liquid, and the sewage medium of the transport contains impurities, silt and other substances; Third, the pump is a type of centrifugal pump. When it runs, the power always increases with the increase of traffic. When the traffic exceeds the design flow and reaches a certain value, the motor will be burned due to overload. The above problems will affect the service life of the submersible sewage pump to varying degrees.

Pump development direction

In response to the problems of pumps, some domestic manufacturers put their energy on the protection system of the development pump: automatically alarm or cut off the power when the pump runs abnormally. Although this method can play a certain effect, and this protection is also necessary, this is not the fundamental method to solve the problem. We also need to focus on improving the performance of the pump and fundamentally solve the problem. In addition, the development of the product must be fully considered to make environmental problems, so that the research and development products are more energy -saving and environmentally friendly.

In summary, the problem that the pump needs to solve in the future is to improve the reliability of use, can adapt to a variety of working environments, optimize its structural design, and further improve the performance of sewage pumps.
