Structure and working principle of ZW self-priming sewage pump

ZW-type self-priming sewage pump structure mainly by the pump body, impeller, back cover, mechanical seals, pump shaft, bearing seat, inlet valve, gas-liquid separation tube, water valve, inlet and outlet and other parts composition. Understand the structure of self-priming sewage pump ZW, then we all know how it works? The following is about ZW-type self-priming sewage pump principle introduction. ZW self-priming sewage pump structure ZW-type self-priming sewage pump working principle is the pump body with a storage chamber, and through the top of the back of the circulation hole and the bottom of the circulation hole with the pump work chamber, constitute the axial pump backflow External mixing system. Pump stopped working, the pump cavity has a certain volume of liquid storage. When the pump starts, the pump liquid under the action of the impeller, the entrained air is thrown up, liquid through the gas-liquid separation tube grid back to the working chamber, the gas is discharged from the pump, the pump to form a certain Vacuum, to achieve the role of self-absorption.
