For the frequent blockage of impurities pump impeller problem, the equipment used in the early stages of each block will be clear, no blocking overnight method. Although this avoids downtime, but often disassemble the pump body, resulting in increased wear and tear of the pump orifice ring and other components at the same time each block costs a lot of manpower. In order to change this kind of situation, install the carbon steel to prevent the dirty box in the water inlet of the pump, and was 45. Inclination. Filter inside the box to filter impurities again to avoid blockage. Monthly team on the pollution 1 to 3 times the pollution. After the implementation of this program has received a certain effect, human consumption has been eased. There is a vent valve at the bottom of the tank, but there are still dead ends. Part of sewage and impurities accumulated in the dead ends, easy to cause minor gas poisoning harm in cleaning, is not conducive to safe operation.
　　
Submersible sewage pump rotor blade morphology is divided into two kinds, respectively, the swirl blade and cutting blade, the blade of these two forms is the most widely used. The swirling impeller does not move in the medium being transported, guides the medium to be pumped into the pump chamber according to the principles of fluid dynamics, and the pumped medium flows by the impeller. In this way, long fibers or solids in the pumped liquid medium are also pumped out together. The cutting blade, can be a large block of solid material chopped, so no longer blocked.
　  Submersible sewage pump anti-clogging performance why will be more and more valued? This is mainly due to two reasons: First, the cost of sewage disposal increased. Industrial companies are working to reduce the water consumption per unit of production, which makes the sewage solids and fiber content is higher and higher. Second, more and more sewage pumps have adopted energy-saving measures, that is, speed regulation drive, but the speed regulation can not guarantee that the sewage pump will not be blocked.
