ZW self-priming sewage pump function self-priming sewage pump manufacturer

Description :

　　ZW series self-priming sewage pump, also known as solid-liquid pump or impurity pump. The hydraulic design of this series of pumps is unique. The impeller is enclosed in a separate impeller chamber, which is connected to a pressurized water chamber. When the impeller rotates, the liquid inside the pump generates a strong axial vortex, creating a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressure chamber, so its flow channel is completely unobstructed, and its discharge effect is unparalleled by other self-priming systems. Easy to install, use, and move, with stable performance and extremely low maintenance rate, it is highly favored by users.

　　Application scope of ZW self-priming sewage pump

　　The ZW series non clogging self-priming sewage pump is widely used in industries such as municipal sewage engineering, light industry, papermaking, textile, food, chemical, electrical, petroleum, mining, and river pond aquaculture. It is currently the ideal impurity pump for pumping solid particles, fibers, slurries, and mixed suspensions in China.

　　Structure and working principle of ZW self-priming sewage pump

　　The ZW series self-priming sewage pump mainly consists of a pump body, impeller, rear cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water inlet valve, inlet and outlet pipes, etc.

　　The working principle of the pump: The pump body is equipped with a liquid storage chamber, which is connected to the pump working chamber through the upper reflux hole and the lower circulation hole, forming an axial reflux external hybrid system of the pump. After the pump stops working There is already a certain volume of liquid stored in the pump chamber. When the pump is started, the stored liquid inside the pump flows back to the working chamber through the grid of the gas-liquid separation tube under the action of the impeller, and the gas is discharged outside the pump, creating a certain degree of vacuum inside the pump and achieving self-priming.
