Different Types Of Sewage Pumps

Sewage pump is a kind of non-clogging pump, with many forms: such as submersible and dry type, dry type sewage pump with cam rotor, mainly used to transport urban sewage, feces or liquid containing fiber, paper scraps For mediums such as solid particles, the temperature of the medium to be conveyed is usually not greater than 80 ¡ãC. Because the conveyed medium contains fibers that are easily entangled or bunched. Therefore, the flow passage of this kind of pump is easy to be blocked. Once the pump is blocked, the pump will not work normally, and even the motor will be burned, resulting in poor sewage discharge. It has a serious impact on urban life and environmental protection. Therefore, blocking resistance and reliability are important factors for the quality of sewage sewage pump.

The most common pressurized water chamber used in sewage sewage pumps is a volute, and radial guide vanes or channel guide vanes are mostly used in built-in submersible pumps. There are three types of volutes: spiral type, annular type and intermediate type. Spiral volutes are basically not used in sewage sewage pumps. The annular pressure water chamber is widely used in small sewage sewage pumps due to its simple structure and convenient manufacturing. However, due to the emergence of the intermediate type (semi-spiral) pressurized water chamber, the application range of the annular pressurized water chamber has gradually become smaller. Because the intermediate type pressurized water chamber has both the high efficiency of the spiral and the high permeability of the annular pressurized water chamber. It has been more and more concerned by manufacturers.
