電磁閥應(yīng)用時(shí)的注意事項(xiàng):
在應(yīng)用電磁閥的過程中,電磁閥的故障將直接影響到切斷閥或控制閥的動(dòng)作,常見的故障為電磁閥發(fā)生拒動(dòng)現(xiàn)象,遇到此類問題時(shí),應(yīng)從以下幾方面排查。
(1)電磁閥接線頭松動(dòng)或線頭脫落,電磁閥不得電,應(yīng)緊固線頭。
(2)電磁閥線圈燒壞,可拆下電磁閥的接線,用萬用表測(cè)量,如果開路,則電磁閥燒壞??赡芤蚓€圈受潮引起絕緣不好而漏磁,造成線圈內(nèi)電流過大而燒毀,因此要防止雨水進(jìn)人電磁閥。此外,彈簧過硬,反作用力過大,線圈匝數(shù)太少,吸力不夠也可使得線圈燒毀。
(3)電磁閥卡住。電磁閥的滑閥套與閥芯的配合間隙很小(<8μm),一般都是單件裝配,當(dāng)有機(jī)械雜質(zhì)帶人或潤滑油太少時(shí),很容易卡住??捎娩摻z從頭部小孔插入,使其彈回,根本的解決方法是將電磁閥拆下,取出閥芯及閥芯套進(jìn)行清洗,使得閥芯在閥套內(nèi)動(dòng)作靈活。
