Unique development of the pump industry after market launch
    Submersible pump development direction , development direction of sewage pump, development direction of submerged sewage pump
    Submersible sewage pump is highly efficient and energy saving, and its structure is novel. After the submersible sewage pump is put on the market, its unique function and reliable quality are welcomed and praised by the majority of users. Non-blocking submersible pumps have been selected by many companies as an alternative to imported products and have been selected as the focus of the introduction of digestion projects by the Machinery Commission.
    Submerged sewage pumps are widely used in the sewage treatment of municipal projects, factories, businesses, hospitals, hotels, residential areas, etc. due to their convenient installation, small footprint, easy maintenance, and no noise. At present, submersible sewage pumps in China 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, due to the need to strengthen the reliability of the sewage pump, so to improve the technical content of its products is the main direction of the future development of manufacturers.
    Problems with current submersible sewage pumps
    The sewage pump is arranged vertically, and the pump is coaxial with the motor, so that the weight of the rotating part is in the same direction as the water pressure the impeller bears. Secondly, the submersible sewage pump is used under liquid and the sewage medium conveyed contains impurities and sludge. Third, the submersible sewage pump is a kind of centrifugal pump. In 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 burned due to overload. .
    The above problems will affect the service life of the sewage pump to varying degrees.
    Development direction of submersible sewage pump
    In response to the problems associated with submersible sewage pumps, some domestic manufacturers have focused their efforts on the development of pump protection systems: Automatically alarm or cut off power supply when an abnormality occurs in the operation of the pump. Although this method can have a certain effect, and this protection is also necessary, but this is not the fundamental method to solve the problem, we must also focus on improving the performance of the pump to fundamentally solve the problem.
    In addition, product development must fully consider the environmental issues, so that the products developed are more energy-efficient and environmentally friendly.
    In summary, the problems to be solved in the future of submersible sewage pumps are to improve the reliability of use, to adapt to various working environments, to optimize their structural design, and to further improve the performance of submersible sewage pumps.
