Background

The supercharger is an inlet AV series or Haskel series air supercharger, and the principle of the supercharger is that the low air pressure of a large-area piston is utilized to generate high hydraulic pressure of a small-area piston. The booster pump is used in the working environment of an original air compression system, wherein the pressure of the working system is increased to 2-5 times, and only compressed air in the working system is required to be used as an air source. The pump is suitable for single-gas-source pressurization. The industrial field is used for clamping a machine tool chuck, inflating an energy accumulator, inflating a high-pressure bottle, reducing compressed gas, converting the compressed gas into high-pressure gas and the like. The booster pump can be used for a mechanical or testing device when the pressure of an air source is not high enough. No matter what causes the pressure drop of the pressure maintaining loop, the German booster pump will start automatically to supplement the leakage pressure and keep the loop pressure constant. It is driven by gas, has no electric arc and spark, and is completely used in the place where there is inflammable and explosive liquid or gas. Compared with other gas-driven pumps, the booster pump can complete the same work, but the parts and the sealing are few, the booster pump with simple maintenance is a plunger pump, the German booster pump rapidly reciprocates during work, the reciprocation of the pump is slowed down until the pump stops along with the increase of the output pressure, the pressure of the pump is constant at the moment, the energy consumption is lowest, and all parts stop moving.
