Press unloading operation；Control gas turns down the aperture of intake valve valve port, and opens cycle unloading valve, maintains system relatively low at one
Pressure under run；
When air compressor machine is shut down, intake valve is closed rapidly, is shut down blow valve and is opened, and the compression being vented in gs-oil separator is empty
Gas makes system pressure be reduced to zero, prepares for air compressor machine light-load starting next time.
By adopting the above scheme, the invention has the advantages that：
1. it is light-load starting to start, the case where avoiding starting load excessive, do not prevented machine；
2. under unloaded state, system internal circular flow, energy conservation and environmental protection under a lower pressure prevent head from breathing heavily
It shakes phenomenon；
3. two grades of system working pressure setting height, is set up by user demand.
In conclusion the air inlet control program of the present invention, may be implemented the light-load starting of air compressor machine, air compressor system is maintained
Low-pressure interior cycle is kept under unloaded state, has two grades of system working pressures, these functions can overcome air compressor machine to start
Difficulty ensures air compressor machine energy-saving run under unloaded state, and according to the high/low work pressure of the job requirements initialization system of client
Power.
