現(xiàn)場快速判斷電磁閥好壞的方法
一,首先檢查是不是電磁閥電磁線圈故障？
在DCS上給二位閥給開或者關(guān)的信號,然后看電磁閥是否得失電,一般在現(xiàn)場聽聲音即可。
若聽不到,那線圈肯定是有問題,至于電磁閥本身是不是有問題？（下面解釋）
如果電磁線圈問題,首先檢查接線,看是不是有虛接,或者有短路現(xiàn)象,如果線路上沒問題就是電磁閥線圈燒壞,可拆下電磁閥的接線,用萬用表測量,如果開路,則電磁閥線圈燒壞。原因有線圈受潮,引起絕緣不好而漏磁,造成線圈內(nèi)電流過大而燒毀,因此要防止雨水進(jìn)入電磁閥。此外,彈簧過硬,反作用力過大,線圈匝數(shù)太少,吸力不夠也可使得線圈燒毀。
二,若線圈是好的,那就是電磁閥本身的問題。
一般可以在手動調(diào)節(jié)處用一字起由1調(diào)到0位置,使閥打開,若是能打開就說明的確是線圈的問題,換個線圈就可以了,若打不開,就拆電磁閥,看是不是閥芯卡住,或者是有雜粒堵,清洗正確應(yīng)該用CCL4,但是考慮到現(xiàn)場沒有條件的話,可以用汽油,實(shí)在沒有用水也可以,清洗后可以用現(xiàn)場儀表氣進(jìn)行吹干,拆時(shí)務(wù)必記好各部件的順序,不注意的話,裝的時(shí)候很容易出錯,順序記錯就算你清洗好電磁閥,即使電磁閥已經(jīng)通了也還是打不開的！
