Causes of Blockage of Submersible Sewage Pump

Submersible sewage pump anti-clogging performance Why is more and more value? This is mainly due to two reasons:

First, the sewage treatment costs increased. Industrial enterprises are working to reduce the water consumption per unit of product, which makes the sewage solids and fiber content is getting higher and higher.

Second, the submersible sewage pump more and more use of energy-saving means, is the speed regulation of the drive, and speed regulation can not guarantee that the sewage pump will not plug.

Impurities for the frequent impaction pump impeller problems, the initial operation of each device will be used to clear, clear overnight blocking method. Although this avoids downtime, but often disassemble the pump, resulting in parts and other parts of the pump pump ring increased wear and tear at the same time each time a lot of manpower. To change this situation, the installation of carbon steel in the pump inlet pipe anti-fouling box, and was 45. Inclination. Use a filter inside the box to filter out impurities again to avoid clogging. Team to conduct a monthly anti-pollution 1 to 3 times the clean-up. After the implementation of this program received a certain effect, human consumption is eased. Anti-fouling the bottom of a vent valve, but there are still dead ends. Part of the sewage and impurities in the corner after the accumulation, in the clean-up easily lead to minor gas poisoning injuries, is not conducive to safe operation.

Diving with submersible sewage pump rotor blade morphology is divided into two kinds, respectively, vortex-type leaves and cutting blades, leaves of these two forms of the most widely used. The swirling impeller does not move in the medium to be conveyed. The medium to be pumped is guided to the pump chamber according to the hydrodynamic principle, and the pumped medium flows from the impeller. Thus, long fibers or solid matter in the pumped liquid medium are also pumped together. The cutting blades, can be a large block of solid material chopped, so no longer plug.
