可编程控制器在氢氮压缩机控制中的应用

Application of PLC in hydrogen and nitrogen compressor controlling

简述了氢氮压缩机辅机电控柜在主机控制中起着非常重要的作用,其工作的可靠程度直接影响到压缩机的安全稳定运行。介绍了早期随设备配套的电控柜在使用过程中多次出现故障,暴露出一些控制缺陷,针对此问题,使用可编程控制器PLC对其进行技术改造后,经过一年多时间的试运行,通过同期数据分析比较,安全稳定运行效果明显,具有较强的实用性和推广性。

The paper briefly introduces nitrogen hydrogen compressor auxiliary engine plays a very important role in main engine control,the reliability of their work directly affects security and stable operation of compressors. It also introduces electronic control cabinet along with equipments matched break down while using,revealed some control weaknesses,for this problems,after using a programmable controller PLC to improve,after more than a year of trial operation,by means of comparing data analysis at the same period,the effect is obvious security and stability,with a strong practical and promotional.
