1.2 儀表自動化故障產生原因分析
針對其一的問題，經過分析發現與係統壓力、導管堵塞、變送器正壓室泄漏及流量計齒輪卡死等，另外，儀表控製參數PID不匹配及工藝操作不適當等，這些問題是導致設備引發的原因。對於其二的問題，多半與儀表負遷量、液麵控製容量過大及工藝係統操作問題等原因造成儀表自動化出現頻繁波動。
2 故障檢測方法
2.1 傳統故障檢測
當自動化設備出現故障時，維修人員可通過傳統觀察、詢問、觸(chu)摸(mo)等(deng)方(fang)式(shi)檢(jian)查(zha)設(she)備(bei)故(gu)障(zhang)，針(zhen)對(dui)儀(yi)表(biao)自(zi)動(dong)化(hua)故(gu)障(zhang)發(fa)生(sheng)的(de)前(qian)後(hou)工(gong)作(zuo)人(ren)員(yuan)要(yao)切(qie)實(shi)了(le)解(jie)清(qing)楚(chu)。另(ling)外(wai)，通(tong)過(guo)切(qie)斷(duan)電(dian)源(yuan)的(de)方(fang)式(shi)觀(guan)察(cha)設(she)備(bei)內(nei)部(bu)元(yuan)器(qi)件(jian)及(ji)接(jie)線(xian)端(duan)子(zi)是(shi)否(fou)變(bian)形(xing)、燒焦及鬆動，通過初步的觀察分析儀表自動化設備的具體故障原因。
2.2 勁儀及HART信號發生器設備檢測
維修人員通過初步的觀察分析後，可通過勁儀、HART等檢查工具測量故障。另外，還可通過替換法的方式，將儀表設備的內外部損壞、對dui損sun壞huai的de儀yi表biao配pei件jian進jin行xing更geng換huan。隨sui著zhe我wo國guo科ke學xue技ji術shu的de不bu斷duan發fa展zhan，自zi動dong化hua設she備bei的de故gu障zhang所suo引yin發fa的de原yuan因yin較jiao多duo，但dan故gu障zhang檢jian測ce工gong具ju也ye得de到dao快kuai速su的de發fa展zhan，企qi業ye隻zhi有you積ji極ji引yin人ren先xian進jin技ji術shu，才cai能neng預yu防fang故gu障zhang頻pin發fa，進jin一yi步bu確que保bao儀yi表biao自zi動dong化hua設she備bei的de正zheng常chang運yun行xing。
