安裝(zhuang)注(zhu)意事項(xiang)： 

1、先要(yao)檢查(cha)電(dian)(dian)(dian)磁閥是否與選型參(can)數一(yi)致，比如(ru)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)、介質壓(ya)(ya)力、壓(ya)(ya)差(cha)等，尤其是電(dian)(dian)(dian)源(yuan)，如(ru)果搞錯，就(jiu)會燒(shao)壞線圈。電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓(ya)(ya)應滿足額定電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)壓(ya)(ya)波動(dong)范(fan)圍：交流+10%~-15%，直(zhi)流+10%~-10%，平時線圈組件不宜拆開。 

2、接(jie)管之前要對(dui)管道進(jin)行沖洗，把管道中的金屬粉末(mo)及密封材(cai)料殘留物，銹(xiu)垢等清除(chu)。要注意介(jie)質(zhi)的潔凈度(du)，如果介(jie)質(zhi)內混(hun)有(you)塵垢，雜質(zhi)等妨礙電磁閥的正常工作(zuo)，管道中應裝過濾(lv)器或濾(lv)網。 

3、一般電(dian)磁閥(fa)的電(dian)磁線圈部件應豎直向上，豎直安裝在水平于(yu)地面的管道，如果受空間限制或(huo)工況要求必(bi)須按(an)側立安裝的，需在選型訂(ding)貨時提出。否則可能造成電(dian)磁閥(fa)不能正(zheng)常工作(zuo)。 

4、電(dian)磁(ci)閥前后(hou)應加手動切斷閥，同(tong)時應設旁路，便于電(dian)磁(ci)閥在(zai)故障(zhang)時維護。

5、電(dian)磁閥一(yi)般是定向的(de)，不可裝(zhuang)反，通常在(zai)閥體上用→指出(chu)介質流動方(fang)向，安裝(zhuang)時要依照(zhao)→指示(shi)的(de)方(fang)向安裝(zhuang)。不過在(zai)真(zhen)空(kong)管(guan)路(lu)或特殊情況(kuang)下(xia)可以反裝(zhuang)。 

6、如(ru)果介質會起水(shui)錘現象(xiang)，那么(me)應該選(xuan)用(yong)具防(fang)(fang)水(shui)錘功能(neng)的電磁(ci)閥或采取(qu)相應的防(fang)(fang)范措施。 

7、盡量不要讓電(dian)磁閥(fa)長時間處于(yu)通電(dian)狀態，這樣(yang)容易降(jiang)低(di)線圈使(shi)用壽命甚至(zhi)燒壞線圈，就是說，常開、常閉(bi)電(dian)磁閥(fa)不可互換使(shi)用。 

8、蒸汽用電磁閥(fa)入(ru)口側應(ying)裝有疏水閥(fa)，該處接(jie)管應(ying)傾斜。 

電磁閥的常見故障(zhang)與排除(chu) 

1、電(dian)(dian)磁閥(fa)通(tong)電(dian)(dian)后不(bu)工(gong)作：檢(jian)查電(dian)(dian)源接(jie)線(xian)是(shi)否(fou)不(bu)良→重新(xin)接(jie)線(xian)和接(jie)插件的連(lian)接(jie)；檢(jian)查電(dian)(dian)源電(dian)(dian)壓(ya)是(shi)否(fou)在工(gong)作范圍(wei)內(nei)-→調到正常(chang)位置(zhi)范圍(wei)；檢(jian)查線(xian)圈是(shi)否(fou)脫焊→重新(xin)焊接(jie)；線(xian)圈短路→更(geng)換(huan)(huan)線(xian)圈；進口(kou)計量(liang)泵(beng)工(gong)作壓(ya)差是(shi)否(fou)不(bu)合適→調整壓(ya)差→或更(geng)換(huan)(huan)相(xiang)稱的電(dian)(dian)磁閥(fa)；流體溫(wen)度過高(gao)→更(geng)換(huan)(huan)相(xiang)稱的電(dian)(dian)磁閥(fa)；有(you)(you)雜質使電(dian)(dian)磁閥(fa)的主閥(fa)芯(xin)和動(dong)鐵芯(xin)卡(ka)死→進行清(qing)洗,如有(you)(you)密封(feng)損(sun)壞應更(geng)換(huan)(huan)密封(feng)并安裝(zhuang)過濾器；液體粘度太(tai)大(da),頻率太(tai)高(gao)和壽命(ming)已到→更(geng)換(huan)(huan)產(chan)品。 

2、電(dian)磁閥(fa)(fa)不能關閉：主閥(fa)(fa)芯或(huo)(huo)動鐵芯的密(mi)封(feng)件(jian)已(yi)損壞→更(geng)換密(mi)封(feng)件(jian)；流(liu)體溫度(du)(du)、粘度(du)(du)是(shi)否過高→更(geng)換對口的電(dian)磁閥(fa)(fa)；有雜質進(jin)入(ru)電(dian)磁閥(fa)(fa)主閥(fa)(fa)芯或(huo)(huo)動鐵芯→進(jin)行清(qing)洗(xi)；彈簧壽(shou)(shou)命(ming)已(yi)到或(huo)(huo)變形→更(geng)換；節(jie)流(liu)孔(kong)平衡(heng)孔(kong)堵塞→及時清(qing)洗(xi)；工作頻率太高或(huo)(huo)壽(shou)(shou)命(ming)已(yi)到→改選(xuan)產品(pin)或(huo)(huo)更(geng)新產品(pin)。 

3、其它(ta)情況(kuang)：內泄漏→檢查密封件是否損壞(huai),彈簧是否裝配(pei)不(bu)良；外泄漏→連接處松(song)動或(huo)(huo)密封件已壞(huai)→緊螺絲(si)或(huo)(huo)更換(huan)密封件；通電(dian)(dian)時(shi)有噪聲→頭(tou)子(zi)上堅固件松(song)動,擰緊。電(dian)(dian)壓(ya)(ya)波動不(bu)在允許范圍內，調整好電(dian)(dian)壓(ya)(ya)。鐵芯(xin)吸合面雜質(zhi)或(huo)(huo)不(bu)平，及(ji)時(shi)清(qing)洗或(huo)(huo)更換(huan)。
