Conventionally, excess compressed air is blown in order to keep the pressure of compressed air in factories constant, and a spare compressor is installed for backup, which is uneconomical. In the air system, the discharge pipe 2 of the compressor 1 installed in each factory and the mother pipe 16 common to all the plants are connected via the connecting pipe 3, and the compressed air system from each plant to the compressed air system common to all the plants is connected. A set of air volume control valve 9 and check valve for supplying compressed air to the factory, and conversely, a backup air volume control valve 10 and a check valve for backing up from the compressed air system common to all plants to the compressed air system in each factory And the air flow transmitter 5 and the pressure transmitter 4 on the mother pipe 15 of the compressed air system in each factory, and the discharge pipe 2 of the compressor 1. A constant air volume controller 6, an FX setter 7, a constant air volume controller that installs air volume transmitters 12 and processes the inputs of these transmitters to adjust the air volume control valve 9 for back feeding and the air volume control valve 10 for backup. Since the programmable indicating controller 11 composed of 8 or the like is provided, the surplus amount of the compressed air supplied from the compressor 1 according to the amount of compressed air used in each factory is used as the mother pipe 16 of the compressed air system common to all the plants. Back to the factory to automatically control the amount of compressed air at each factory to a set value to minimize the amount of compressed air blown at each factory and stop the compressor 1 installed at each factory due to an accident. Or, if the amount of compressed air used in each factory suddenly increases and the pressure of the compressed air drops, the main pipe 16 of the compressed air system that is common to all the plants is changed to the system in each plant. Automatically supplying compressed air for backup the required amount to the substrate tube 15.
As a result, the compressed air system in each factory with large load fluctuations can be blown to the compressed air system in other factories without discharging the compressed air system in other factories. Is possible. Further, when the compressor 1 is stopped due to an accident in the compressed air system in each factory, compressed air can be automatically sent from other factory systems, and the compressed air is stabilized without installing the backup compressor 1. Can operate. In addition, by applying this compressed air system to an expansion plant at a business establishment where a plurality of similar plants are provided, it is possible to expect many merits such as reduction of facility cost and reduction of power.
