  Introduction of ZW self - absorption unblocking sewage pump

ZW, FBX, FSZ and other self-priming pumps are not to be filled (the first time still needs to be irrigated), but the pump itself can absorb the water and put it into operation.

The principle of self-priming pump is divided into the following categories:

1) gas-liquid mixing (including internal and external mixing);

2) water ring wheel type;

3) flow type (including liquid jet and gas jet).

The working process of the gas-liquid hybrid self-priming pump: try to make a certain amount of water pump memory at ordinary times, after the pump starts due to the effect of rotation of the impeller, suction pipe, air and water to mix adequately and be into the gas water separation chamber.Gas water separation chamber upper gas evolution, the lower the water returned to the impeller, and suction pipe residual gas mixture again, until all the gas in the pump and inlet pipe road line, complete the imbibition, and normal pumping.

The water ring wheel is composed of the water ring wheel and the pump impeller in a shell, the gas is discharged by the water ring wheel, and the self-absorption is realized.

The jet type self-priming pump is composed of a centrifugal pump and a jet pump, which relies on the injection device to create a vacuum at the nozzle.
