Home self-priming pump works

Self-priming pump can be used with the internal combustion engine, but also can be mounted on a mobile car, this advantage makes it possible to operate in the field, a large number of self-priming pumps, household self-priming pump is one of the more classic Masterpiece, with the use of household self-priming pumps continue to expand, the understanding of the working principle of home self-priming pump has also become a lot of users want to do. Household self-priming pump working principle Household self-priming pump according to the principle of action is divided into the following categories: gas-liquid hybrid, water ring wheel, jet. 1, the working process of gas-liquid hybrid self-priming pump: Due to the special structure of the self-priming pump body, after the pump stops, there is a certain amount of water in the pump body. After the pump starts again, due to the rotation of the impeller, And the water is fully mixed, and was discharged to the gas-water separation chamber, the gas above the gas-water separation chamber overflows, the lower part of the water back to the impeller, re-intake pipe and the remaining air mixture until the pump and suction pipe all the gas discharge, Complete self-absorption, and normal pumping. 2, water ring wheel self-priming pump is the water ring and pump impeller combination in a shell, with the water ring to the gas discharge, to achieve self-absorption. When the pump is working properly, the valve of the water ring and the pump impeller can be cut off by the valve, and the liquid in the water ring wheel can be released. 3, jet-type self-priming pump, a centrifugal pump and jet pump combination, relying on the jet device, resulting in a vacuum nozzle to achieve suction. Through the above-mentioned gas-liquid hybrid, water ring wheel, jet three kinds of equipment working principle analysis, we can more clearly understand the working condition of household self-priming pump. With the domestic self-priming pump in our life plays an increasingly important role, I believe the development of such products will receive more attention.
