德國力(li)士樂(le)電磁閥可靠性：

1、工作壽命，此項不列入出廠試(shi)驗項目，屬于型(xing)式試(shi)驗項目。為確保質量應選正規廠家的名pai產品。

2、工(gong)作(zuo)(zuo)制式：分(fen)長期工(gong)作(zuo)(zuo)制，反復短(duan)時(shi)工(gong)作(zuo)(zuo)制和(he)短(duan)時(shi)工(gong)作(zuo)(zuo)制三(san)種。對于長時(shi)間閥(fa)門開通(tong)只有短(duan)時(shi)關閉(bi)的情況(kuang)，則宜選用常開電磁閥(fa)。

3、工作頻率：動(dong)(dong)作頻率要求高時，結構應優選直動(dong)(dong)式電(dian)磁閥(fa)，電(dian)源(yuan)聽(ting)優選交流。

4、動作可靠性

嚴格地來說此項試驗尚未正式列入中國(guo)電磁閥(fa)專業(ye)標準，為確保(bao)質量應(ying)選正規廠家的名pai產品。有些場合動作次數(shu)并(bing)不多，但對(dui)可靠性(xing)要求卻(que)很高，如消防(fang)、緊急保(bao)護等 ，切不可掉以輕心。特別(bie)重(zhong)要的，還(huan)應(ying)采取(qu)兩只連(lian)用雙保(bao)險。

德國力士樂電磁(ci)閥安裝方(fang)法： 

1、先要(yao)(yao)檢查(cha)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)是(shi)否(fou)與選型參數一(yi)(yi)致(zhi)，比如(ru)電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)壓、介(jie)質(zhi)壓力、壓差等(deng)(deng)，尤其是(shi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)，如(ru)果搞錯(cuo)，就會燒壞(huai)線(xian)圈。電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)壓應滿(man)足額定(ding)電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)壓波動(dong)范圍：交流+10%~-15%，直(zhi)(zhi)流+10%~-10%，平時線(xian)圈組件(jian)不(bu)宜(yi)拆開。 2、一(yi)(yi)般電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)的(de)(de)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)線(xian)圈部(bu)件(jian)應豎直(zhi)(zhi)向上，豎直(zhi)(zhi)安裝(zhuang)(zhuang)(zhuang)在(zai)水平于地(di)面(mian)的(de)(de)管道，如(ru)果受空間限制或(huo)工(gong)況要(yao)(yao)求必須(xu)按(an)側立(li)安裝(zhuang)(zhuang)(zhuang)的(de)(de)，需在(zai)選型訂貨時提出(chu)。否(fou)則可(ke)能(neng)造成電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)不(bu)能(neng)正常工(gong)作。 3、接管之前要(yao)(yao)對(dui)管道進行沖洗，把管道中(zhong)的(de)(de)金屬(shu)粉(fen)末及密封材(cai)料殘留物，銹(xiu)垢等(deng)(deng)清(qing)除。要(yao)(yao)注意(yi)介(jie)質(zhi)的(de)(de)潔凈度，如(ru)果介(jie)質(zhi)內(nei)混(hun)有塵垢，雜質(zhi)等(deng)(deng)妨(fang)礙電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)的(de)(de)正常工(gong)作，管道中(zhong)應裝(zhuang)(zhuang)(zhuang)過濾器或(huo)濾網。 4、如(ru)果介(jie)質(zhi)會起水錘現象，那么(me)應該選用具防水錘功能(neng)的(de)(de)電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)或(huo)采取相應的(de)(de)防范措施。 5、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)前后(hou)應加手(shou)動(dong)切斷閥(fa)，同時應設旁路，便(bian)于電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)在(zai)故障(zhang)時維護(hu)。 6、電(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)一(yi)(yi)般是(shi)定(ding)向的(de)(de)，不(bu)可(ke)裝(zhuang)(zhuang)(zhuang)反(fan)，通常在(zai)閥(fa)體上用→指出(chu)介(jie)質(zhi)流動(dong)方(fang)向，安裝(zhuang)(zhuang)(zhuang)時要(yao)(yao)依(yi)照(zhao)→指示的(de)(de)方(fang)向安裝(zhuang)(zhuang)(zhuang)。不(bu)過在(zai)真空管路或(huo)特殊(shu)情(qing)況下可(ke)以(yi)反(fan)裝(zhuang)(zhuang)(zhuang)。
