Working principle

The working principle of an air compressor involves several key components and processes.

Inlet and outlet valves

The inlet valve allows atmospheric air to enter the compressor, while the outlet valve controls the release of compressed air from the storage tank. These valves ensure proper air flow and pressure regulation.

Piston movement or rotor rotation

In reciprocating air compressors, the piston moves up and down to compress the air. In rotary screw compressors, the interlocking screws rotate in opposite directions, trapping and compressing the air.

Compression of air

As the piston moves or the screws rotate, the air is compressed, reducing its volume and increasing its pressure. This is achieved by confining the air within a smaller space, forcing its molecules closer together.

Discharge of compressed air

Once the air is compressed, it is stored in a tank or discharged directly for immediate use. The compressed air can be released at the desired pressure through various outlets and connections.
