PLC控制技术在采空区瓦斯抽采方面的应用

The Application of PLC Control Technology in Gob Gas Drainage

利用PLC控制技术实现对采空区瓦斯抽采管路的温度、主要气体浓度等参数的采集,对真空泵、循环水泵、冷却风扇和主管道电动调节阀门等设备的实时调节,给出了PLC控制的工艺要求和控制逻辑表,得到了很好的运行结果。

The data acquisition of temperature,primary gas density and other parameters which existed in the gas drainage pipeline of the gob is achieved by taking advantage of PLC control technology,and real time adjustment of vacuum air pump,water circulating pump,cooling fan and major pipe electromotion regulating valve and other devices is achieved.The technological requirements and control logic table of PLC control technology is given,and it has a good run results.
