摘要
项目采用西门子S7-300可编程控制器对空气压缩机组及采用气体千爆设备的控制系统进行改造,解决继电器线路复杂、故障率高、可靠性差以及维护困难等问题。经运行检验,改造后的空气压缩机组PLC控制系统操作简便,可靠性高、安全、稳定。
This paper introduced the transformation of Siemens S7-300 PLC on the use of air compressors and gas drying equipment control system, to resolve complex relay lines, the high failure rate. poor reliability and maintenance problems and other issues. After running tests, the transformation of the air compressor group PLC control system is simple, high reliability, security and stability.
