An air pump is a mechanical device that compresses gas or liquid through changes in air pressure. Its core operating principle relies on the movement of a piston or diaphragm (typically within a pressure range of 0.5-1.2 MPa). In the automotive industry, air pumps provide compressed air for tire inflation (standard tire pressure 2.2-2.5 bar), engine starting, and manufacturing processes such as painting (spraying pressure 0.3-0.6 MPa). In the construction industry, air pumps are used for high-intensity operations such as water pumping (head lift 20-50 meters) and concrete spraying (output pressure 0.7-1 MPa), improving construction efficiency by over 30%. In the manufacturing industry, air pumps drive pneumatic tools (operating pressure 0.6-0.8 MPa) and testing equipment, significantly reducing labor costs.
