First, ZW non-clogging self-suction sewage pump structure and working principle ZW series self-priming non-clogging sewage pump, mainly by the pump. Impeller, back cover, mechanical seal, pump shaft, bearing, inlet valve, gas-liquid separation Pipe, add water valves, split, row take over and other components. Pump structure shown in Figure. The working principle of the pump: The pump body is provided with a liquid storage cavity, which is communicated with the pump working cavity through the upper return hole and the circulation hole below to form a pump axial return external mixed system. After the pump stops working, the pump cavity has a certain volume of liquid stored. When the pump starts, the pump liquid in the impeller, the entrainment of the air is up? Out of liquid through the gas-liquid separation pipe 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.
