REXROTH電磁閥接線頭松動(dòng)或線頭脫落，電磁閥不得電，可緊固線頭。
力士樂電磁閥線圈燒壞，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，力士樂電磁閥彈簧過硬，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)按鈕正常工作時(shí)的位打到位，使得閥打開。
力士樂電磁閥卡住。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REXROTH電磁閥拆下，取出閥芯及閥芯套，用CCI4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。 上海維特銳在德國(guó)與REXROTH合作，可長(zhǎng)期穩(wěn)定供應(yīng)REXROTH電磁閥，REXROTH換向閥，REXROTH油泵，REXROTH導(dǎo)軌，力士樂柱塞泵等產(chǎn)品
