Air Compressors

A machine used for the production of compressed air. It consists of a piston compressor with power supplied by an electric motor, a refrigerator and a tank.
Its working principle is air compression: air is taken from the atmosphere, compressed by the compressor and collected into a tank. A filter is fitted at the intake to prevent foreign particles from going into the cylinder head.
A cooling coil removes the condensate created by the heating of compressed air.

Below we will expand on the use of solenoid valves in air compressors.

The Application of Solenoid Valves in Air Compressors

When the system is operating, the electric motor runs the compressor, which takes in filtered air, compresses it, sends it to the refrigerator and finally to the tank.
During this stage, the solenoid valve is energized and closes the circuit keeping it under pressure. When the tank reaches the requested pressure reading, a pressure switch stops the motor and the check valve keeps the air inside the tank.
To prevent the compressor from remaining under pressure for too long and so getting damaged, the solenoid valve is then de-energized, and it allows exceeding air still in the circuit to be exhausted.
