SMC電磁閥SY5120-5LZD-01的故障和排除
閱讀：2194 發(fā)布時(shí)間：2018-5-7SMC電磁閥SY5120-5LZD-01的故障和排除
一、SMC電磁閥SY5120-5LZD-01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SMC電磁閥SY5120-5LZD-01
流體溫度過(guò)高→更換相稱的SMC電磁閥SY5120-5LZD-01
有雜質(zhì)使SMC電磁閥SY5120-5LZD-01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、SMC電磁閥SY5120-5LZD-01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SMC電磁閥SY5120-5LZD-01
有雜質(zhì)進(jìn)入SMC電磁閥SY5120-5LZD-01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。
