以下介紹PLC的常見故障:
1、*類故障點(也是故障zui多的地點)在繼電器、接觸器。
如生產(chǎn)線PLC控制系統(tǒng)的日常維護(hù)中,電氣備件消耗量zui大的為各類繼電器或空氣開關(guān)。主要原因除產(chǎn)品本身外,就是現(xiàn)場環(huán)境比較惡劣,接觸器觸點易打火或氧化,然后發(fā)熱變形直至不能使用。所以減少此類故障應(yīng)盡量選用高性能繼電器,改善元器件使用環(huán)境,減少更換的頻率,以減少其對系統(tǒng)運行的影響。

2、第二類故障多發(fā)點在閥門或閘板這一類的設(shè)備上。
因為這類設(shè)備的關(guān)鍵執(zhí)行部位,相對的位移一般較大,或者要經(jīng)過電氣轉(zhuǎn)換等幾個步驟才能完成閥門或閘板的位置轉(zhuǎn)換,或者利用電動執(zhí)行機構(gòu)推拉閥門或閘板的位置轉(zhuǎn)換,機械、電氣、液壓等各環(huán)節(jié)稍有不到位就會產(chǎn)生誤差或故障。*使用缺乏維護(hù),機械、電氣失靈是故障產(chǎn)生的主要原因,因此在系統(tǒng)運行時要加強對此類設(shè)備的巡檢,發(fā)現(xiàn)問題及時處理。我廠對此類設(shè)備建立了嚴(yán)格的點檢制度,經(jīng)常檢查閥門是否變形,執(zhí)行機構(gòu)是否靈活可用,控制器是否有效等,很好地保證了整個控制系統(tǒng)的有效性。
