Control of Pressure after A Compressor
Control of Pressure after A Compressor
In a pneumatic system, energy delivered by a compressor is not generally used
immediately, but is stored as potential energy in air receiver tank in the form of
compressed air.
In most instances, a compressor is designed into a system so that it operates
intermittently. A compressor usually delivers
compressed air to a receiver tank until
high pressure is reached, then it is shut down.
When air pressure in the tank
decreases, the compressor cuts in and recharges the tank. Intermittent compressor
operation in this manner is a power saving benefit for the system.
decreases, the compressor cuts in and recharges the tank. Intermittent compressor
operation in this manner is a power saving benefit for the system.
A common way of sensing tank pressure and controlling actuation and de-actuation
of relatively small (2-15 HP) compressors, is with a pressure switch.
