Sewage pumps are a type of centrifugal impurity pumps, which have various forms: such as submersible and dry types. Commonly used submersible types are QW submersible sewage pumps. Common dry sewage pumps are W-type horizontal sewage pumps and WL. Two types of vertical sewage pumps. It is mainly used to transport urban sewage, which contains fibers in feces or liquids. The medium of solid particles such as paper dust is usually transported at a temperature not greater than 80°C. Because the conveyed medium contains fibers that are easily entangled or bunched. Therefore, this kind of pump flow channel is easy to be blocked. Once the pump is blocked, the pump will not work properly, or even burn the motor, resulting in poor sewage.
The existing sewage pump base is not firmly connected to the sewage pump, which causes great harm to the sewage pump during operation. The sewage pump cannot suck mud during operation. The sewage pump is damaged due to the twisting of the mud, and the service life of the sewage pump is reduced.
