Submersible sewage pumps are widely used in shopping malls, municipal engineering, factories, commerce, hospitals, hotels, residential areas and other sewage discharge due to their advantages of simple installation, small footprint, convenient maintenance, and no noise. At present, China’s domestic submersible sewage pumps are mainly produced and manufactured by domestic manufacturers, and a small part of the products are imported from abroad. The market prospect is very broad. However, as the reliability of submersible sewage pumps needs to be strengthened, improving the technical content of their products is the main direction for manufacturers in the future.
Problems with submersible sewage pumps:
The submersible sewage pump is arranged vertically, and the pump is coaxial with the motor, so that the weight of the rotating parts is in the same direction as the water pressure on the impeller; secondly, the submersible sewage pump is used under liquid, and the sewage medium conveyed contains impurities, Silt and other substances; third, the submersible sewage pump is a kind of centrifugal pump. During its operation, the power always increases with the increase of the flow. When the flow exceeds the design flow and reaches a certain value, the motor will be overloaded. burn. The above problems will affect the service life of the submersible sewage pump to varying degrees.
The development direction of submersible sewage pumps:
In response to the problems of submersible sewage pumps, some Chinese manufacturers have focused their efforts on the development of pump protection systems: automatically alarm or cut off the power supply when the pump runs abnormally. Although this method can have a certain effect, and this kind of protection is also necessary, it is not the fundamental way to solve the problem. We also need to focus on improving the performance of the pump to solve the problem fundamentally.
In addition, the development of products must take environmental issues into full consideration, so that the products developed are more energy-saving and environmentally friendly. In summary, the problem that the submersible sewage pump needs to solve in the future is to improve the reliability of use, adapt to a variety of working environments, optimize its structural design, and further improve the performance of the submersible sewage pump.
