摘要
随着化工企业发展,仪表及控制系统的作用也越发显著。许多企业又苦于对仪表及控制系统故障的处理。文章给出了"制氢小螺杆压缩机喷液阀不动作、PIC4202不能实现自动控制、操作站流程图不能显示"三种故障的分析与处理,收到良好的效果。
with the development of chemical industry, instrumentation and control system becomes more and more significant. Many enterprises also suffer from processing to the failure of instrumentation and control system. This paper gives a ＂hydrogen small screw compressor liquid spraying valve does not work, PIC4202 can not realize the analysis and processing of automatic con- trol, operation flow chart can not display the＂ three kinds of fault, received good results.
