電磁閥故障與排除 一、電磁閥通電后不工作 檢查電源接線是否不良→重新接線和接插件的連接 檢查電源電壓是否在±工作范圍-→調(diào)致正常位置范圍 線圈是否脫焊→重新焊接 線圈短路→更換線圈 工作壓差是否不合適→調(diào)整壓差→或更換相稱的電磁閥 流體溫度過(guò)高→更換相稱的電磁閥 有雜質(zhì)使電磁閥的主閥芯和動(dòng)鐵芯卡死→進(jìn)行清洗,如有密封損壞應(yīng)更換密封并安裝過(guò)濾器 液體粘度太大,頻率太高和壽命已到→更換產(chǎn)品 二、電磁閥不能關(guān)閉 主閥芯或鐵動(dòng)芯的密封件已損壞→更換密封件 流體溫度、粘度是否過(guò)高→更換對(duì)口的電磁閥 有雜質(zhì)進(jìn)入電磁閥產(chǎn)閥芯或動(dòng)鐵芯→進(jìn)行清洗 彈簧壽命已到或變形→更換 節(jié)流孔平衡孔堵塞→及時(shí)清洗 工作頻率太高或壽命已到→改選產(chǎn)品或更新產(chǎn)品 三、其它情況 內(nèi)泄漏→檢查密封件是否損壞,彈簧是否裝配不良 外泄漏→連接處松動(dòng)或密封件已壞→緊螺絲或更換密封件 通電時(shí)有噪聲→頭子上堅(jiān)固件松動(dòng),擰緊。電壓波動(dòng)不在允許范圍內(nèi),調(diào)整好電壓。鐵芯吸合面雜質(zhì)或不平,及時(shí)清洗或更換。現(xiàn)場(chǎng)快速判斷電磁閥好壞方法
