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(lè)電磁閥線圈燒壞,，可拆下電磁閥的接線,，用萬(wàn)用表測(cè)量，如果開(kāi)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(guò)大而燒毀,，因此要防止雨水進(jìn)入電磁閥。

    此外,，力士樂(lè)電磁閥彈簧過(guò)硬,，反作用力過(guò)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(kāi)。

    力士樂(lè)電磁閥卡住,。電磁閥的滑閥套與閥芯的配合間隙很?。ㄐ∮?.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(lè)柱塞泵等產(chǎn)品
