Why Is The Anti Clogging Performance Of Submersible Sewage Pump More And More Valued

Oct 12, 2021

Why is the anti clogging performance of submersible sewage pump more and more valued? This is mainly due to two reasons: first, the increase of sewage treatment cost. Industrial enterprises are trying to reduce the water consumption per unit product, which makes the content of solid matter and fiber in sewage higher and higher. Second, the sewage pump is increasingly using energy-saving means, that is, the driving mode of speed regulation, but the speed regulation can not ensure whether the sewage pump will be blocked.

To solve the problem of frequent blockage of pump impeller by impurities, the method of clearing every blockage and not clearing it overnight is adopted in the early stage of equipment operation. Although this avoids shutdown, the pump body is often disassembled, resulting in increased wear of pump port ring and other components. At the same time, it takes a lot of manpower to clear the blockage each time. In order to change this situation, a carbon steel anti fouling tank with an inclination of 45. Is installed at the water inlet pipe of the pump. Filter screen is used in the box to filter impurities again to avoid blockage. The team shall clean the sewage once or three times a month. After the implementation of this scheme, a certain effect has been received and the labor consumption has been alleviated. There is a vent valve at the bottom of the trash trap, but there is still a dead corner. After some sewage and impurities accumulate in the dead corner, it is easy to cause slight gas poisoning injury to personnel during cleaning, which is not conducive to safe operation.

The rotor blades of submersible sewage pump can be divided into two types: swirl blades and cutting blades, which are widely used. The swirling impeller does not move in the conveyed medium. According to the principle of hydrodynamics, the medium to be pumped is guided into the pump cavity, and the pumped medium flows next to the impeller. In this way, long fibers or solid substances in the pumped liquid medium are also pumped out together. The cutting blade can cut large block solid materials, so that they are no longer blocked.
