Type ZCQ self-priming magnetic pump (works):

The pump uses external mixing axial back to the pump structure, pump pipette rooms, liquid storage room, volute, back hole, gas-liquid separation chamber part of the composition, structure shown in Figure 1. Pump starts, the effect of centrifugal force, the remaining liquid in the suction chamber and the inlet pipe of the air impeller stirred into a mixture of gas ice mixture into the gas-liquid separation chamber through the volute, with the slow down, resulting in gas water separation, air discharged from the pump out the fluid port Kong return of the fluid by backwater pump, after several cycles, the air inlet pipe is the net emission of the formation of a certain degree of vacuum pump to achieve a self-priming role.
