PLC在空分切换系统中的应用

PLC Apply in Switching System of the Air Separation Equipment

切换系统是空分设备中一个重要环节,介绍其控制系统的工作原理,分析该控制方式的弊端,结合现场实际,提出用可编程序控制器代替原有落后的控制系统。经实施后收到了良好效果,PLC运行稳定,切换系统工作平稳,保证了空分设备的平稳运行及氧气的正常供应。

Switching system is an important aspect of the air separated equipment. The principle of the control system is introduced. Under the condition of analyzing the shortcomings of the older control system and by combining with the experience in field, is carefully engineered to replace the outdated control system by PLC. Excellent effects are obtained in practical implementation. The PLC is stable operating and the oxygen can be produced uninterrupted by the control system operating stably.
