Development of non - clogging submersible sewage pump
Non-clogging sewage pump for the vertical arrangement of the pump and motor coaxial, so that the weight of the rotating parts and impeller water pressure direction to the same; followed by non-clogging submersible sewage pump is used in the transport of sewage medium containing impurities , Sludge and other substances; the third non-clogging submersible sewage pump is a kind of centrifugal pump, in its running power is always increased with the flow increases, when the flow exceeds the design flow and reaches a certain value of the motor will be overloaded burn. These problems will affect the different degrees of non-clogging sewage pump life.
For non-clogging submersible sewage pump problems, some domestic manufacturers to focus on the development of the pump protection system: in the pump operation occurs automatically when the alarm or cut off the power. Although this approach can play a certain effect, and this protection is necessary, but this is not the fundamental way to solve the problem, we also need to focus on improving the performance of the pump on the fundamental solution to the problem. Non-clogging sewage pump problem to be solved in the future is to improve the reliability of use to adapt to a variety of working conditions, optimize its structural design to further improve the performance of sewage pumps.
The non-clogging submersible sewage pump is widely used in the municipal engineering, factory, commercial, hospital, hotel, residential area and so on because of its simple installation, small footprint, convenient maintenance and no noise. At present, China's domestic non-clogging sewage pump mainly by the domestic manufacturers to produce and manufacture a small part of the products imported from abroad. However, due to non-clogging submersible sewage pump reliability aspects to be strengthened, so to improve the technical content of their products is the main direction of future development of manufacturers.
