Definitions

  • Japanese Patent No.2,875,702 discloses a method of controlling a plurality of compressors in a system in which compressed gases from a plurality of compressors are gathered into a pressure tank of which a required compressed gas is taken out.
  • the upper limit of pressure is kept to 0.2 MPa higher than used pressure to increase difference between the upper and lower limits.
  • Compressed gases such as compressed air
  • compressed air outputted from a plurality of compressors are gathered into a pressure tank.
  • a required amount of compressed air is taken out of the pressure tank and employed.
  • the compressed gases are not always gathered into the pressure tank, but may be taken out of conduits directly.
  • Electromagnetic switches 3 comprising E 1 to E 8 turn the motors M 1 to M 8 on and off respectively.
  • a stop signal is transmitted from the control 9 to the electromagnetic switch E 4 for the compressor No.4 (C 4 ) via the operating portion 12 to stop the compressor No.4.
  • the five compressors No.1 and Nos. 5 to 8 still run.
  • a stop signal is transmitted from the control 9 to the electromagnetic switch E 5 for the compressor No.5 (C 5 ) via the operating portion 12 to stop the compressor No.5.
  • the four compressors No.1 and Nos. 6 to 8 still run.
  • a stop signal is transmitted from the control 9 to the electromagnetic switch E 6 for the compressor No.6 (C 6 ), which stops.
  • the three compressors Nos. 1, 7 and 8 still run.
  • a stop signal is transmitted from the control 9 to the electromagnetic switch E 7 for the compressor No.7 (C 7 ) via the operating portion 12 to stop the compressor No.7.
  • the two compressors Nos. 1 and 8 still run.
  • a stop signal is transmitted from the control 9 to the electromagnetic switch E 1 for the compressor No.1 (C 1 ), which stops. All the compressors do not run.
  • a start signal is transmitted from the control 9 to the electromagnetic switch E 2 for the compressor No.2 (C 2 ) which secondly stops, via the operating portion 12, to start the compressor No.2.
  • the seven compressors No. 1 and Nos. 2 to 8 do not run yet.
  • a start signal is transmitted from the control 9 to the electromagnetic switch E 3 for the compressor No.3 (C 3 ) which thirdly stops, via the operating portion 12, to start the compressor No.3.
  • the compressors No. 1 and Nos.4 to 8 do not run yet.
  • a start signal is transmitted from the control 9 to the electromagnetic switch E 5 for the compressor No.5 (C 5 ) which stops fifthly, via the operating portion 12 to start the compressor No.5.
  • the compressors No.1 and Nos.6 to 8 do not run yet.
  • a start signal is transmitted from the control 9 to the electromagnetic switch E 8 for the compressor No.8 (C 8 ) which stops eighthly, via the operating portion to start the compressor No.8. Only the. compressor No. 1 does not run yet.
  • a start signal is transmitted from the control 9 to electromagnetic switch E 1 for the compressor No.1 (C 1 ) which stops ninthly, via the operating portion 12 to start the compressor No.1. All the compressors Nos. 1 to 8 run, and there is no compressor that does not run.
