Single-machine protection control is a control system for each air compressor, and its control object is the various protection settings of a single air compressor.
Joint protection control is that multiple air compressors share a control cabinet, and its control object is multiple air compressors connected to the joint control cabinet, and can be connected to the DCS operating system in the control room; The main contents of joint protection control are air compressor host setting and switching, single-machine joint control start and stop sequence and delay, etc., to maintain the balance of running time of each air compressor.
