Title: Parallel operation method and device for prural compressors
Inventor: KANETANI RYUGO
IPC: F04D27/02
Filed: 1987-03-27
Abstract: PURPOSE:To enable the power loss due to blowoff to be reduced by operating only one cut of a plurality of compressors in a constant-air-pressure plus on-off control mode, and by operating the others in a constant-air-pressure mode. CONSTITUTION:An overall load supervisory control unit 12 gives a command of constant-air-pressure plus on-off control to a compressor 1a, and a command of constant-air-pressure control to compressors 1b and 1c. Thereby, since the compressors 1b and 1c being mode base machines are operated under a constant air pressure control, all the operating machines can be throttled up to the surging limit. Accordingly, the operation is carried out so that the compressor 1a being a mode regulating machine may not enter no-load operation as far as possible, and if once the mode regulating machine enters no-load operation, the mode base machines under constant-air-pressure control are variable within the nonsurging limit, thus even the mode base machines can balance with a wide variety of air consumption. Further, the operation is carried out not to enter no-load operation region as far as possible, so that the load/no-load changeover frequency of the mode regulating machine can be reduced, and the power loss due to blowoff can be effectively reduced.
