下麵我們從組成設備的三部分來了解一下診斷自動化設備故障的方法。
1． 檢查自動化設備的所有電源，氣源，液壓源
電(dian)源(yuan)，氣(qi)源(yuan)和(he)液(ye)壓(ya)源(yuan)的(de)問(wen)題(ti)會(hui)經(jing)常(chang)導(dao)致(zhi)自(zi)動(dong)化(hua)設(she)備(bei)出(chu)現(xian)故(gu)障(zhang)。比(bi)如(ru)供(gong)電(dian)出(chu)現(xian)問(wen)題(ti)，包(bao)括(kuo)整(zheng)個(ge)車(che)間(jian)供(gong)電(dian)的(de)故(gu)障(zhang)，比(bi)如(ru)電(dian)源(yuan)功(gong)率(lv)低(di)，保(bao)險(xian)燒(shao)毀(hui)，電(dian)源(yuan)插(cha)頭(tou)接(jie)觸(chu)不(bu)良(liang)等(deng)；氣(qi)泵(beng)或(huo)液(ye)壓(ya)泵(beng)未(wei)開(kai)啟(qi)，氣(qi)動(dong)三(san)聯(lian)件(jian)或(huo)二(er)聯(lian)件(jian)未(wei)開(kai)啟(qi)，液(ye)壓(ya)係(xi)統(tong)中(zhong)的(de)泄(xie)荷(he)閥(fa)或(huo)某(mou)些(xie)壓(ya)力(li)閥(fa)未(wei)開(kai)啟(qi)等(deng)。檢(jian)測(ce)自(zi)動(dong)化(hua)設(she)備(bei)時(shi)應(ying)包(bao)括(kuo)以(yi)下(xia)幾(ji)個(ge)方(fang)麵(mian)：a、電源，包括每台設備的供電電源和車間的動力電。b、氣源，包括氣動裝置所需的氣壓源。c、液壓源，包括自動化設備液壓裝置需要的液壓泵的工作情況。
2． 檢查自動化設備的傳感器位置是否出現偏移

4． 檢查電氣，氣動和液壓回路連接
如(ru)果(guo)以(yi)上(shang)三(san)步(bu)都(dou)沒(mei)有(you)發(fa)現(xian)任(ren)何(he)問(wen)題(ti)，那(na)麼(me)檢(jian)查(zha)所(suo)有(you)回(hui)路(lu)。查(zha)看(kan)電(dian)路(lu)中(zhong)的(de)導(dao)線(xian)是(shi)否(fou)出(chu)現(xian)斷(duan)路(lu)，尤(you)其(qi)是(shi)線(xian)槽(cao)內(nei)的(de)導(dao)線(xian)是(shi)否(fou)由(you)於(yu)拉(la)扯(che)被(bei)線(xian)槽(cao)剮(gua)斷(duan)。檢(jian)查(zha)氣(qi)管(guan)是(shi)否(fou)有(you)損(sun)壞(huai)性(xing)的(de)折(zhe)痕(hen)。檢(jian)查(zha)液(ye)壓(ya)油(you)管(guan)是(shi)否(fou)堵(du)塞(sai)。如(ru)果(guo)氣(qi)管(guan)出(chu)現(xian)嚴(yan)重(zhong)折(zhe)痕(hen)，立(li)刻(ke)更(geng)換(huan)。液(ye)壓(ya)油(you)管(guan)一(yi)樣(yang)要(yao)更(geng)換(huan)。
在(zai)保(bao)證(zheng)上(shang)述(shu)步(bu)驟(zhou)無(wu)誤(wu)後(hou)，故(gu)障(zhang)才(cai)有(you)可(ke)能(neng)出(chu)現(xian)在(zai)自(zi)動(dong)化(hua)設(she)備(bei)的(de)控(kong)製(zhi)器(qi)中(zhong)，但(dan)永(yong)遠(yuan)不(bu)可(ke)能(neng)是(shi)程(cheng)序(xu)問(wen)題(ti)。首(shou)先(xian)，不(bu)要(yao)肯(ken)定(ding)是(shi)控(kong)製(zhi)器(qi)毀(hui)壞(huai)，隻(zhi)要(yao)沒(mei)有(you)出(chu)現(xian)過(guo)嚴(yan)重(zhong)的(de)短(duan)路(lu)，控(kong)製(zhi)器(qi)內(nei)部(bu)都(dou)具(ju)有(you)短(duan)路(lu)保(bao)護(hu)，一(yi)般(ban)性(xing)的(de)短(duan)路(lu)不(bu)會(hui)燒(shao)毀(hui)控(kong)製(zhi)器(qi)。
