電磁閥的常見故障與排除
1、電(dian)(dian)磁(ci)閥(fa)(fa)通(tong)電(dian)(dian)后不工作：檢(jian)(jian)查電(dian)(dian)源接(jie)線是(shi)否不良→重新接(jie)線和(he)接(jie)插(cha)件(jian)的連接(jie)；檢(jian)(jian)查電(dian)(dian)源電(dian)(dian)壓是(shi)否在工作范圍(wei)(wei)內-→調到(dao)正常位置范圍(wei)(wei)；檢(jian)(jian)查線圈是(shi)否脫焊→重新焊接(jie)；線圈短路→更換(huan)(huan)(huan)線圈；工作壓差是(shi)否不合適→調整壓差→或(huo)更換(huan)(huan)(huan)相(xiang)稱(cheng)的電(dian)(dian)磁(ci)閥(fa)(fa)；流(liu)體溫(wen)度過(guo)高→更換(huan)(huan)(huan)相(xiang)稱(cheng)的電(dian)(dian)磁(ci)閥(fa)(fa)；有雜質使電(dian)(dian)磁(ci)閥(fa)(fa)的主閥(fa)(fa)芯和(he)動(dong)鐵(tie)芯卡死(si)→進行清洗,如有密封(feng)損(sun)壞應更換(huan)(huan)(huan)密封(feng)并安(an)裝過(guo)濾(lv)器(qi)；液體粘度太大(da),頻率太高和(he)壽命已到(dao)→更換(huan)(huan)(huan)產品。
2、電(dian)磁閥(fa)(fa)不能關閉：主閥(fa)(fa)芯(xin)(xin)或(huo)鐵動(dong)芯(xin)(xin)的(de)密封(feng)件已損壞→更(geng)(geng)換密封(feng)件；流體(ti)溫度(du)、粘度(du)是(shi)否過高→更(geng)(geng)換對口的(de)電(dian)磁閥(fa)(fa)；有雜質進入電(dian)磁閥(fa)(fa)主閥(fa)(fa)芯(xin)(xin)或(huo)動(dong)鐵芯(xin)(xin)→進行清洗；彈簧壽(shou)命(ming)已到(dao)或(huo)變形(xing)→更(geng)(geng)換；節流孔平衡孔堵塞→及時清洗；工作頻率太高或(huo)壽(shou)命(ming)已到(dao)→改選產品或(huo)更(geng)(geng)新產品。
3、其它情(qing)況：內(nei)泄(xie)漏→檢查密封(feng)(feng)件(jian)(jian)是否(fou)損壞,彈(dan)簧(huang)是否(fou)裝配不良(liang)；外泄(xie)漏→連接處(chu)松動(dong)或(huo)密封(feng)(feng)件(jian)(jian)已壞→緊(jin)螺絲或(huo)更換(huan)密封(feng)(feng)件(jian)(jian)；通電時有噪(zao)聲→頭子上堅固件(jian)(jian)松動(dong),擰緊(jin)。電壓波動(dong)不在允許范圍內(nei)，調整好(hao)電壓。鐵芯(xin)吸合面雜質或(huo)不平，及時清洗或(huo)更換(huan)。
