電磁閥的常見故障與排除
1、電(dian)磁(ci)閥(fa)通電(dian)后不(bu)工(gong)作(zuo)：檢查電(dian)源(yuan)接線(xian)(xian)是(shi)(shi)否不(bu)良(liang)→重新接線(xian)(xian)和(he)接插件(jian)的連接；檢查電(dian)源(yuan)電(dian)壓是(shi)(shi)否在(zai)工(gong)作(zuo)范圍內-→調到(dao)正常位置范圍；檢查線(xian)(xian)圈(quan)是(shi)(shi)否脫(tuo)焊→重新焊接；線(xian)(xian)圈(quan)短路→更(geng)換(huan)線(xian)(xian)圈(quan)；工(gong)作(zuo)壓差是(shi)(shi)否不(bu)合適→調整壓差→或更(geng)換(huan)相(xiang)稱的電(dian)磁(ci)閥(fa)；流體(ti)溫度過高(gao)→更(geng)換(huan)相(xiang)稱的電(dian)磁(ci)閥(fa)；有雜質使電(dian)磁(ci)閥(fa)的主閥(fa)芯和(he)動(dong)鐵芯卡死(si)→進(jin)行(xing)清洗(xi),如有密封(feng)損壞應更(geng)換(huan)密封(feng)并安裝過濾器；液體(ti)粘度太大,頻率(lv)太高(gao)和(he)壽命已到(dao)→更(geng)換(huan)產(chan)品(pin)。
2、電磁(ci)閥不(bu)能關閉：主(zhu)閥芯(xin)或鐵動芯(xin)的(de)密(mi)封件(jian)已(yi)損壞→更(geng)(geng)換(huan)(huan)密(mi)封件(jian)；流體(ti)溫度、粘度是否過高→更(geng)(geng)換(huan)(huan)對口的(de)電磁(ci)閥；有雜質進入電磁(ci)閥主(zhu)閥芯(xin)或動鐵芯(xin)→進行清洗；彈(dan)簧壽(shou)命(ming)已(yi)到或變形→更(geng)(geng)換(huan)(huan)；節流孔(kong)平衡孔(kong)堵塞→及時清洗；工作頻率太高或壽(shou)命(ming)已(yi)到→改選產品或更(geng)(geng)新產品。
3、其它情況：內(nei)泄漏(lou)→檢查(cha)密封(feng)件是否(fou)(fou)損壞,彈簧(huang)是否(fou)(fou)裝(zhuang)配不(bu)良；外泄漏(lou)→連接處松(song)動(dong)或(huo)(huo)(huo)密封(feng)件已壞→緊螺絲或(huo)(huo)(huo)更(geng)換密封(feng)件；通電時有噪聲→頭(tou)子上堅固件松(song)動(dong),擰緊。電壓波動(dong)不(bu)在允許(xu)范圍內(nei)，調整(zheng)好電壓。鐵芯吸合面雜質(zhi)或(huo)(huo)(huo)不(bu)平，及時清洗(xi)或(huo)(huo)(huo)更(geng)換。
