介绍了变压吸附装置停车后程控阀内漏的排查方法以及通过不同生产负荷下 CO 纯度变化趋势和 CO 纯度周期性波动趋势图判断程控阀门内漏的方法。由于变压吸附装置程控阀较多，且开、关频率较高，为了保证装置的长周期运行，应切实加强程控阀的日常维护工作，发现问题及早检修，避免造成事故扩大化。
介紹瞭變壓吸附裝置停車後程控閥內漏的排查方法以及通過不同生產負荷下 CO 純度變化趨勢和 CO 純度週期性波動趨勢圖判斷程控閥門內漏的方法。由于變壓吸附裝置程控閥較多，且開、關頻率較高，為瞭保證裝置的長週期運行，應切實加彊程控閥的日常維護工作，髮現問題及早檢脩，避免造成事故擴大化。

The inner leakage checking method for program-controlled valve after pressure swing adsorption (PSA)unit shutdown and the inner leakage judgment method for program-controlled valve through CO purity change trend and CO purity cyclical swing trend diagram under different production load are presented.Because there are many program-controlled valves in pressure swing adsorption unit and they turn on and off frequently,in order to ensure long period operation of the unit,concrete steps must be taken to strengthen the daily maintenance work of program-controlled valves,problems are maintained timely if they are discovered to avoid the enlargement of accident.
