Working principle and scope of application of ZW self-priming non-blocking sewage pump

Overview: ZW self-priming non-clogging sewage pump has simple structure, good self-priming performance, strong sewage discharge capacity, 

high efficiency and energy saving, and easy use and maintenance. Various technical performances are leading in China and have reached the

 international advanced level, with broad application market and development prospects

Working principle of ZW self-priming non-clogging sewage pump: There is a liquid storage chamber in the pump body, which is connected to

 the pump working chamber through the upper reflux hole and the lower circulation hole, forming the axial flow addition external mixing system

 of the pump. After the ZW self-priming sewage pump stops working, a certain volume of liquid has been stored in the pump cavity. When the pump

 starts, the liquid stored in the relevant authorities is thrown upward with air under the action of the impeller, and the liquid flows back to the working

 chamber through the grid of the gas-liquid separation tube, and the gas is discharged out of the pump, so that a certain vacuum is formed in the pump

 to achieve the effect of self-priming.

ZW self-priming non-clogging sewage pump is widely used in the discharge of seriously polluted wastewater from factories and commerce, sewage

 discharge stations in main residential areas, water distribution systems of urban sewage treatment plants, drainage stations of civil air defense systems,

 water supply equipment of water plants, sewage discharge from hospitals and hotels, municipal engineering construction sites, supporting equipment

 of mines, rural biogas pools, farmland irrigation and other industries. It can convey sewage and dirt with particles, and can also be used for clean water 

and weakly corrosive media.
