Working principle of sewage discharge pump

  The impeller and pressure chamber of sewage discharge pumps are the two core elements of sewage pumps. The advantages and disadvantages of its performance represent the superior performance of the pump. The anti clogging performance, efficiency, and cavitation performance of the sewage discharge pump are guaranteed by the two major components of the blade pump and the pressure water chamber.

  The working principle and characteristics of sewage discharge pumps belong to a type of non clogging pump, which has various forms, such as submersible and dry. The most common type of submersible sewage pump is the WQ type, and the most common dry sewage pump is the W-type horizontal sewage pump and the WL type vertical sewage pump. Mainly used for transporting urban sewage, feces, or liquids containing fibers. The medium for solid particles is usually transported at a temperature not exceeding 80 ℃. Due to the presence of fibers that are prone to entanglement or bunching in the medium being transported. Therefore, it is easy to block the pump flow channel. Once the pump is blocked, it can cause the pump to not work properly, and even burn out the motor, resulting in poor drainage. It has a serious impact on urban life and environmental pollution. Therefore, an important factor in anti clogging and reliability is the quality of the sewage pump.

  In terms of performance, sewage pumps have a steep head curve and a relatively flat power curve.

  The most common type of pressure chamber used in sewage pumps is the volute, and in internally installed submersible pumps, radial guide vanes or flow channel guide vanes are often used. There are three types of snail shells: spiral, annular, and intermediate. Spiral volutes are basically not used in sewage pumps. Circular pressurized water chambers are commonly used in small sewage pumps due to their simple structure and convenient manufacturing. However, due to the emergence of intermediate (semi spiral) pressure chambers, the application range of annular pressure chambers gradually decreases. Due to the high efficiency of the spiral and the high permeability of the annular pressurized water chamber, the intermediate pressurized water chamber has both advantages. It has received increasing attention from manufacturers.
