style="text-indent:25px">選擇的電磁閥額定工作壓力太高，會增加投資但選擇的額定工作壓力太低，或接近實(shí)際的介質(zhì)壓力，在工作中電磁閥因材料的強(qiáng)度不夠，會造成事故。除安全問題外，工作壓力的選擇還與電磁閥能否正常工作有關(guān)。工作壓力一般用較高與較低的上、下限來確定它的可靠工作范圍。否則電磁閥受介質(zhì)壓力的影響將無法可靠工作。介質(zhì)流量大小關(guān)系到電磁閥選擇時(shí)的通徑或閥座尺寸。如果所選電磁閥口徑過大，會造成經(jīng)濟(jì)上的浪費(fèi)，增加安裝費(fèi)用，但口徑選小了問題也多，如會限制管道中應(yīng)通過的流量，并造成較大的壓力損失使得系統(tǒng)的控制作用減小，使系統(tǒng)的控制精度下降或失控。</p><p style="text-indent:25px">電磁閥有常閉型和常開型二種。常閉型斷電時(shí)呈關(guān)閉狀態(tài)，當(dāng)線圈通電時(shí)產(chǎn)生電磁力，使動鐵芯克服彈簧力同靜鐵芯吸合直接開啟閥，介質(zhì)呈通路；當(dāng)線圈斷電時(shí)電磁力消失，動鐵芯在彈簧力的作用下復(fù)位，直接關(guān)閉閥口，介質(zhì)不通。結(jié)構(gòu)簡單，動作可靠，在零壓差和微真空下正常工作。常開型正好相反。如小于φ6流量通徑的電磁閥。原理：常閉型通電時(shí)，電磁線圈產(chǎn)生電磁力把敞開件從閥座上提起，閥門打開；斷電時(shí)，電磁力消失，彈簧把敞開件壓在閥座上，閥門敞開。電磁閥選型先應(yīng)該依次遵循安全性，可靠性，適用性，經(jīng)濟(jì)性四大原則。</p><div

style="text-indent:25px">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(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?，F(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(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。防爆電磁閥的安全性:腐蝕性介質(zhì)，對于強(qiáng)腐蝕的介質(zhì)必須選用隔離膜片式。江蘇防爆電磁閥排行榜</p><p style="text-indent:25px">電磁閥允許液體粘度一般在20CST以下，大于20CST應(yīng)注明。江蘇防爆電磁閥排行榜</p><p style="text-indent:25px">防爆電磁閥在安裝前，要注意看清產(chǎn)品標(biāo)牌，認(rèn)真閱讀使用說明書，判斷產(chǎn)品是否符合使用條件。防爆電磁閥的工作介質(zhì)應(yīng)清潔無顆粒雜質(zhì)，防爆電磁閥內(nèi)件表面上的污物及過濾器，需定期清潔干凈。安裝時(shí)防爆電磁閥線圈向上，并保持垂直位置，電磁閥上箭頭或標(biāo)記應(yīng)與管道流向一致，不得安裝在有濺水或漏水的地方。在管路系統(tǒng)中，安裝在支路上的防爆電磁閥通徑應(yīng)小于主管道閥門的通徑。安裝防爆電磁閥前，管道必須清洗干凈。建議在閥前安裝過濾器，蒸汽管道安裝疏水閥。不能將閥安裝在管道的低凹處，以免因蒸汽冷凝水、雜質(zhì)等沉淀在閥內(nèi)而防礙動作。電磁閥前后管道上需安裝壓力表，以便觀察管道壓力。在管路剛性不足情況下，建議把閥前管道用支架固定，以免防爆電磁閥工作時(shí)引起振動。在防爆電磁閥發(fā)生故障時(shí)，為了及時(shí)隔離防爆電磁閥，并保證系統(tǒng)正常運(yùn)行，較好安裝旁路裝置江蘇防爆電磁閥排行榜</p></p><br
