Extended data:
Air pump, also called air pump, air pump and air pump, works by the operation of motor. When pumping air, the atmospheric pressure pushes the valve of the communication device open, and the gas enters the air pump. When the tire is inflated, the valve is closed by the air pressure in the air pump, and the gas enters the tire.
Pneumatic booster pumps are divided into gas-liquid booster pumps and gas booster pumps. The principle of gas-liquid booster pump is to use the low air pressure of large-area piston to generate high hydraulic pressure of small-area piston. Various gas drives: compressed air, nitrogen, water vapor, natural gas, etc. It can be used as the driving air source of the pump. Wide application range: used for clamping machine tool chuck, inflating accumulator, inflating high-pressure bottle, transforming reduced pressure gas into high-pressure gas, etc. Where the air pressure is not high enough, the booster pump can be used for both mechanical equipment and test equipment.
