The working principle of a booster pump? The booster pump is filled with liquid, and then start the centrifugal pump, the impeller rotates rapidly, the impeller blade drive makes the liquid rotate, the liquid rotation depends on inertia to the outer edge of the impeller flow, at the same time the impeller from the suction chamber into the liquid.

In this process, the liquid in the impeller flows around the blade, the liquid acts a lift force on the blade in the movement around the flow, and the blade in turn uses a force equal to the lift force and in the opposite direction for the liquid, the force does work on the liquid, so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.

The single gas control non-balanced gas distribution valve is used to realize the automatic reciprocating movement of the pump, and the gas drive part of the pump body is made of aluminum alloy. The liquid part chooses carbon steel or stainless steel according to the different medium.

General pump has intake, exhaust two ports, in the intake can produce lower than normal pressure (that is, atmospheric pressure) gas pressure is called “negative pressure”; In the exhaust port can produce higher than the atmospheric pressure called “positive pressure”; For example, the vacuum pump is often said to be negative pressure pump, booster pump is positive pressure pump. Positive pressure pumps are very different from negative pressure pumps. For example, the gas flow direction, the negative pressure pump is the external gas is sucked into the suction nozzle; The positive pressure is sprayed out of the exhaust nozzle; Such as the level of pressure and so on.
