費斯托FESTO電磁閥線圈常見問題及解決辦法
費斯(si)托FESTO電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)的故障(zhang)將(jiang)直接(jie)影響(xiang)到(dao)切換閥(fa)(fa)和(he)調節閥(fa)(fa)的動作(zuo)，常見的故障(zhang)有(you)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)不動作(zuo)，應從以(yi)下(xia)幾(ji)方面排(pai)查：（1）電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)接(jie)線(xian)頭(tou)(tou)(tou)(tou)松動或線(xian)頭(tou)(tou)(tou)(tou)脫落，電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)不得(de)(de)電(dian)(dian)(dian)(dian)(dian)，可(ke)緊固線(xian)頭(tou)(tou)(tou)(tou)。（2）費斯(si)托FESTO電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)線(xian)圈燒壞(huai)，可(ke)拆下(xia)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)的接(jie)線(xian)，用(yong)(yong)萬用(yong)(yong)表測量，如果開(kai)路(lu)，則電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)線(xian)圈燒壞(huai)。原因有(you)線(xian)圈受潮，引起緣不而(er)漏(lou)磁(ci)(ci)(ci)，造成線(xian)圈內電(dian)(dian)(dian)(dian)(dian)流過(guo)大而(er)燒毀，因此(ci)要(yao)(yao)防止雨水(shui)進入(ru)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)。此(ci)外(wai)，彈簧過(guo)硬，反(fan)作(zuo)用(yong)(yong)力過(guo)大，線(xian)圈匝數太(tai)少(shao)，吸力不夠(gou)也(ye)可(ke)使(shi)得(de)(de)線(xian)圈燒毀。緊急處理時，可(ke)將(jiang)線(xian)圈上的手動按鈕由正(zheng)常工作(zuo)時的“0”位打(da)(da)到(dao)“1”位，使(shi)得(de)(de)閥(fa)(fa)打(da)(da)開(kai)。（3）電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)卡住(zhu)。電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)的滑(hua)閥(fa)(fa)套與閥(fa)(fa)芯(xin)(xin)的配合間隙很(hen)小（小于0.008mm），般(ban)都是(shi)單件裝(zhuang)配，當有(you)機械(xie)雜質帶入(ru)或潤滑(hua)油(you)太(tai)少(shao)時，很(hen)容易卡住(zhu)。處理方法可(ke)用(yong)(yong)鋼絲從頭(tou)(tou)(tou)(tou)部(bu)小孔捅(tong)入(ru)，使(shi)其彈回(hui)。根(gen)本的解決方法是(shi)要(yao)(yao)將(jiang)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)閥(fa)(fa)拆下(xia)，取出(chu)閥(fa)(fa)芯(xin)(xin)及閥(fa)(fa)芯(xin)(xin)套，用(yong)(yong)CCI4清洗(xi)，使(shi)得(de)(de)閥(fa)(fa)芯(xin)(xin)在閥(fa)(fa)套內動作(zuo)靈活。拆卸時應注意各部(bu)件的裝(zhuang)配順(shun)序及外(wai)部(bu)接(jie)線(xian)位置，以(yi)便重新(xin)裝(zhuang)配及接(jie)線(xian)正(zheng)確，還要(yao)(yao)檢(jian)查油(you)霧器噴(pen)油(you)孔是(shi)否堵(du)塞，潤滑(hua)油(you)是(shi)否足夠(gou)。
費斯托FESTO電(dian)磁閥線(xian)(xian)圈常見(jian)問題是你的(de)電(dian)壓(ya)或時(shi)間(jian)上使用不當造成過熱(re)而(er)燒(shao)糊，這是常見(jian)。再就是因本身不內部(bu)線(xian)(xian)圈接出來處接觸不再因經常性(xing)的(de)振動或電(dian)流(liu)通過造成該接電(dian)點斷路。解決(jue)的(de)辦法主要(yao)看你用的(de)產品了。如不是體密封式的(de)或鉚接的(de)那可類(lei)同交(jiao)流(liu)接觸器的(de)只(zhi)換線(xian)(xian)圈。否(fou)則可就只(zhi)有整體換總(zong)程了
