The invention provides a compression device and an operation control method thereof. A control time T is set according to service lifetimes of the air compressors (12a-d) and surrounding devices. And the time when the number of the air compressor changes is taken as a start point t0 of the control time T. After the control time I passes and when a pressure changing volume Delta P of the injected compressed air achieves or surpasses a predetermined increase volume Delta PS, a controller (30) controls an electromagnetic shutter (16a-d) to switch one of the compressors from a loading state to an unloading state. |
