一起制氧机组分子筛控制系统故障分析及解决

摘要

Power switch tripping of the solenoid valve for molecular sieve led to exces-sive pressure at the outlet of air compressor and emptying of the interlocked venting valve, affecting production of the oxygen generator and the economic performance of the company. Based on the work process of molecular sieve process and configuration of the control system, the causes of the control system failure were analyzed and a solution to the problem was found. The technical modification measures were also introduced.%由于分子筛电磁阀柜电源开关跳闸，导致空压机出口压力超限，联锁空压机放空阀放空，影响制氧机组的生产和公司的经济效益。结合分子筛工作过程和控制系统的组成，分析了控制系统故障的原因，找到了解决问题的方法，介绍了技术改造措施。
