Title:
COMPRESSED GAS PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/102812
Kind Code:
A1
Abstract:
Provided is a compressed gas production device with which it is possible to reduce maintenance cost in correspondence to the total operation time of a plurality of gas compressors. A control device 4 includes a total operation time estimation unit 10 which estimates the total operation time of the gas compressors 1A to 1E at the time of future maintenance. A storage unit 11 stores a control table of the relationship between the total operation time of the gas compressors 1A to 1E and an upper limit value of the operation time of each of the gas compressors corresponding to a maintenance rank of each gas compressor, the control table being set such that as the total operation time increases, the number of gas compressors having relatively high maintenance rank gradually increases. A priority setting unit 12, using the control table, sets the upper limit value of the operation time of each gas compressor in accordance with the total operation time estimated by means of the total operation time estimation unit 10, and, on the basis of this, sets the priority of each gas compressor. An operation number control unit 13 controls the number of gas compressors that are operated, and selects a gas compressor to be operated on the basis of the priority set by means of the priority setting unit 12.
