Sewage pump is a kind of centrifugal impurity pump, which has many forms, such as submersible pump and dry pump. The most common submersible pump is QW submersible sewage pump, and the most common dry sewage pump is W horizontal sewage pump and WL vertical sewage pump. Mainly used to transport cities; Fiber is contained in sewage, feces or liquids. The temperature of solid particle media such as paper scraps is usually not higher than 80 ° C. The conveyed medium contains fibers that are easy to be wound 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, or even burn the motor, resulting in poor sewage discharge. It has a serious impact on urban life and environmental protection. Therefore, anti blocking and reliability are important factors for sewage pumps.
Sewage pumps can be divided into: submerged sewage pumps, pipeline sewage pumps, submersible sewage pumps, vertical sewage pumps, corrosion resistant sewage pumps, acid resistant sewage pumps, and self-priming sewage pumps. Sewage pump models include PW sewage pump and PWL sewage pump.
The most common type of pressure chamber used by PW sewage pump is volute. Radial guide vanes or runner guide vanes are mostly used in built-in submersible pumps.
PWL sewage pump impeller and water pressure chamber are the two core components of sewage pump. The quality of its performance also represents the quality of the pump performance.
With the progress of society, the continuous improvement of people's living standards and the strengthening of environmental awareness, sewage pumps have become familiar with people, and their application scope has become increasingly broad.
