Ordinary centrifugal pump, if the suction liquid level is below the impeller, it should be pre-filled with water when starting, which is very inconvenient. In order to keep the liquid in the pump and in the suction pipe, the inlet of the suction pipe needs to be equipped with a bottom valve. When the pump is working, the bottom valve causes a large hydraulic loss. The so-called self-priming pump broadly includes various realCombination device of empty equipment and centrifugal pump, such as water ring wheel self-priming pump and jet self-priming pump and combination of other types of vacuum equipment and centrifugal pump; in a narrow sense, it refers to centrifugal pump that can make the pump itself have the ability to pump vacuum by changing the structure .
The centrifugal pump has a certain gas-liquid mixing capacity. The self-priming pump utilizes the ability of the centrifugal pump to mix the liquid with the gas and then discharge it through a special structure, so as to achieve the purpose of vacuuming and sucking the liquid in the inlet pipe. Usually, the self-priming pump depends on where the liquid and gas are mixed in the pump.It can be divided into two types: internal mixing and external mixing. The liquid in the gas-liquid separation chamber returns to the inlet of the impeller, and the gas and liquid are mixed at the inlet of the impeller, which is called an internal mixing self-priming pump. The liquid in the gas separation chamber returns to the outlet of the impeller, and the gas and liquid are mixed at the edge of the impeller, which is called external mixing.self-priming pump
