| Abstract: | The faults of air compressor interlock shutdown and anti-surging valve full open in air separation unit are caused by signal interference existing in instrument transmission line. Optimization and modification of the hardware and control program are carried out. By isolating the analog signal transmission cable from the logic signal transmission cable effectively, the hidden dangers of the control system are eliminated, and the normal operation of the air compressor is guaranteed. |
