淺談：德國FESTO電磁閥線圈的維修方法
   德國FESTO電磁閥的應用很廣，它在換向閥中的作用很大換向閥有時候會出現故障，就是由于電磁線圈出問題了。
　　換(huan)向閥的故(gu)障(zhang)有(you)：閥不能(neng)換(huan)向或換(huan)向動作(zuo)緩慢，氣體(ti)泄漏，德(de)國FESTO電(dian)磁閥有(you)故(gu)障(zhang)等。關于發揮行(xing)業(ye)網(wang)站(zhan)作(zuo)用、推進(jin)行(xing)業(ye)信息(xi)工作(zuo)的通知

         (1)換(huan)(huan)(huan)(huan)向(xiang)(xiang)閥不能換(huan)(huan)(huan)(huan)向(xiang)(xiang)或(huo)換(huan)(huan)(huan)(huan)向(xiang)(xiang)動作緩慢，一般是(shi)因潤(run)滑(hua)不良、彈(dan)簧被卡住或(huo)損(sun)壞、油污或(huo)雜質卡住滑(hua)動部分等原因引(yin)起的(de)(de)。對此，應先(xian)檢(jian)查(cha)油霧器的(de)(de)工作是(shi)否正常；潤(run)滑(hua)油的(de)(de)粘度(du)是(shi)否合適。必要時，應更換(huan)(huan)(huan)(huan)潤(run)滑(hua)油，清洗(xi)換(huan)(huan)(huan)(huan)向(xiang)(xiang)閥的(de)(de)滑(hua)動部分，或(huo)更換(huan)(huan)(huan)(huan)彈(dan)簧和(he)換(huan)(huan)(huan)(huan)向(xiang)(xiang)閥。

         (2)換向閥(fa)(fa)(fa)(fa)經長時(shi)間使用(yong)后易出現(xian)閥(fa)(fa)(fa)(fa)芯密(mi)封圈(quan)(quan)磨損、閥(fa)(fa)(fa)(fa)桿和(he)閥(fa)(fa)(fa)(fa)座(zuo)損傷的現(xian)象，導致閥(fa)(fa)(fa)(fa)內氣體泄漏，閥(fa)(fa)(fa)(fa)的動作緩慢或不能正常換向等故障。此時(shi)，應更換密(mi)封圈(quan)(quan)、閥(fa)(fa)(fa)(fa)桿和(he)閥(fa)(fa)(fa)(fa)座(zuo)，或將(jiang)換向閥(fa)(fa)(fa)(fa)換新。

         (3)若電(dian)(dian)(dian)(dian)磁先(xian)導閥(fa)的(de)(de)進、排氣孔被油泥等雜物堵(du)塞，封(feng)閉不(bu)(bu)嚴，活動鐵(tie)芯被卡(ka)死，電(dian)(dian)(dian)(dian)路(lu)有故(gu)障等，均可導致換(huan)(huan)向(xiang)(xiang)(xiang)閥(fa)不(bu)(bu)能(neng)正(zheng)常(chang)換(huan)(huan)向(xiang)(xiang)(xiang)。對(dui)前(qian)3種情況應清洗先(xian)導閥(fa)及活動鐵(tie)芯上的(de)(de)油泥和雜質(zhi)。而電(dian)(dian)(dian)(dian)路(lu)故(gu)障一(yi)般又分為(wei)控制(zhi)電(dian)(dian)(dian)(dian)路(lu)故(gu)障和電(dian)(dian)(dian)(dian)磁線圈故(gu)障兩類。在檢(jian)查電(dian)(dian)(dian)(dian)路(lu)故(gu)障前(qian)，應先(xian)將換(huan)(huan)向(xiang)(xiang)(xiang)閥(fa)的(de)(de)手動旋鈕(niu)轉動幾下(xia)(xia)，看(kan)換(huan)(huan)向(xiang)(xiang)(xiang)閥(fa)在額(e)定(ding)(ding)的(de)(de)氣壓(ya)(ya)下(xia)(xia)是(shi)否能(neng)正(zheng)常(chang)換(huan)(huan)向(xiang)(xiang)(xiang)，若能(neng)正(zheng)常(chang)換(huan)(huan)向(xiang)(xiang)(xiang)，則是(shi)電(dian)(dian)(dian)(dian)路(lu)有故(gu)障。檢(jian)查時，可用(yong)儀表測(ce)量電(dian)(dian)(dian)(dian)磁線圈的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)，看(kan)是(shi)否達到了(le)額(e)定(ding)(ding)電(dian)(dian)(dian)(dian)壓(ya)(ya)，如(ru)果電(dian)(dian)(dian)(dian)壓(ya)(ya)過低，應進一(yi)步檢(jian)查控制(zhi)電(dian)(dian)(dian)(dian)路(lu)中(zhong)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)和相關聯的(de)(de)行程開關電(dian)(dian)(dian)(dian)路(lu)。如(ru)果在額(e)定(ding)(ding)電(dian)(dian)(dian)(dian)壓(ya)(ya)下(xia)(xia)換(huan)(huan)向(xiang)(xiang)(xiang)閥(fa)不(bu)(bu)能(neng)正(zheng)常(chang)換(huan)(huan)向(xiang)(xiang)(xiang)，則應檢(jian)查電(dian)(dian)(dian)(dian)磁線圈的(de)(de)接頭(插頭)是(shi)否松(song)動或(huo)接觸(chu)不(bu)(bu)實。方法是(shi)，拔下(xia)(xia)插頭，測(ce)量線圈的(de)(de)阻值，如(ru)果阻值太大或(huo)太小，說明(ming)電(dian)(dian)(dian)(dian)磁線圈已損壞(huai)，應更換(huan)(huan)。
