| Abstract: | There were design defects in switching action program of the air inlet valve of the No.1 and No.2 molecular sieves of the 40000 m3/h air separator.To avoid abnormal action of the valve in production,the improvement measures were advanced.The improved control system was inspected.The abnormal action of the valve in production was avoided and the stability of the process was kept. |
| Keywords: | molecular sieve air inlet and outlet valve sequence control program action condition time-delay closing function block |
