現(xiàn)場(chǎng)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(hào),然后看電磁閥是否得失電,一般在現(xiàn)場(chǎng)聽聲音即可。
若聽不到,那線圈肯定是有問(wèn)題,至于電磁閥本身是不是有問(wèn)題？（下面解釋）
如果電磁線圈問(wèn)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(méi)問(wèn)題就是電磁閥線圈燒壞,可拆下電磁閥的接線,用萬(wàn)用表測(cè)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(guò)大而燒毀,因此要防止雨水進(jìn)入電磁閥。此外,彈簧過(guò)硬,反作用力過(guò)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(wèn)題。
一般可以在手動(dòng)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(shuō)明的確是線圈的問(wèn)題,換個(gè)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(chǎng)沒(méi)有條件的話,可以用汽油,實(shí)在沒(méi)有用水也可以,清洗后可以用現(xiàn)場(chǎng)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(cuò),順序記錯(cuò)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！

減壓閥的作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓,水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。定比減壓原理是利用閥體中浮動(dòng)活塞的水壓比控制,進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無(wú)振動(dòng)；閥體內(nèi)無(wú)彈簧,故無(wú)彈簧銹蝕,金屬疲勞失效之慮；密封性能良好不滲漏,因而既減動(dòng)壓（水流動(dòng)時(shí)）又減靜壓（流量為0時(shí)）；特別是在減壓的同時(shí)不影響水流量。
