產(chǎn)品詳情
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，則電磁閥線圈燒壞。原因有線圈受潮，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)入電磁閥。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。緊急處理時(shí)，可將線圈上的手動(dòng)按鈕由正常工作時(shí)的“0"位打到“1"位，使得閥打開。
電磁閥卡住。電磁閥的滑閥套與閥芯的配合間隙很小(小于0.008mm)，一-般都是單件裝配,當(dāng)有機(jī)械雜質(zhì)帶入或潤(rùn)滑油太少時(shí)，很容易卡住。處理方法可用鋼絲從頭部小孔捅入，使其彈回。根本的解決方法是要將電磁閥拆下，取出閥芯及閥芯套，用清洗，使得閥芯在閥套內(nèi)動(dòng)作靈活。拆卸時(shí)應(yīng)注意各部件的裝配順序及外部接線位置,以便重新裝配及接線正確，還要檢查油霧器噴油孔是否堵塞，潤(rùn)滑油是否足夠。
