詳解德國FESTO電磁閥線圈故障解決方法主要有那些
一，德國FESTO電(dian)磁閥線圈(quan)的作用(yong)　　

德國FESTO電(dian)(dian)磁閥(fa)線(xian)(xian)圈(quan)(quan)(quan)(quan)內的(de)(de)(de)活動(dong)(dong)鐵心(xin)(xin)(xin)在閥(fa)通電(dian)(dian)時(shi)為線(xian)(xian)圈(quan)(quan)(quan)(quan)所(suo)吸引(yin)移動(dong)(dong)，帶(dai)動(dong)(dong)閥(fa)芯(xin)移動(dong)(dong)，從而改變閥(fa)的(de)(de)(de)導通狀態(tai)；所(suo)謂干(gan)式(shi)或濕式(shi)僅指(zhi)線(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)(de)工作環境，對閥(fa)動(dong)(dong)作而言(yan)，沒大區別。但(dan)是我們知道，一(yi)個空心(xin)(xin)(xin)線(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)(de)電(dian)(dian)感(gan)量與(yu)在該線(xian)(xian)圈(quan)(quan)(quan)(quan)內加入鐵芯(xin)后的(de)(de)(de)電(dian)(dian)感(gan)量是不(bu)(bu)同(tong)(tong)的(de)(de)(de)，前者要小，后者大，當(dang)線(xian)(xian)圈(quan)(quan)(quan)(quan)通以交流電(dian)(dian)時(shi)，線(xian)(xian)圈(quan)(quan)(quan)(quan)所(suo)產生的(de)(de)(de)阻(zu)抗(kang)也就(jiu)不(bu)(bu)一(yi)樣， 對同(tong)(tong)一(yi)線(xian)(xian)圈(quan)(quan)(quan)(quan)，加上同(tong)(tong)一(yi)頻率的(de)(de)(de)交流電(dian)(dian)時(shi)，電(dian)(dian)感(gan)量將隨鐵心(xin)(xin)(xin)位置不(bu)(bu)同(tong)(tong)而變化，即其阻(zu)抗(kang)隨鐵心(xin)(xin)(xin)位置不(bu)(bu)同(tong)(tong)而變化，阻(zu)抗(kang)小時(shi)，流經線(xian)(xian)圈(quan)(quan)(quan)(quan)的(de)(de)(de)電(dian)(dian)流將增加。

二，德國FESTO電磁閥(fa)線圈常過暖的原(yuan)因　

當 德(de)國FESTO電磁閥的線(xian)圈是按工(gong)作(zuo)狀態(tai)（通(tong)電）時(shi)，鐵(tie)心被吸(xi)合，形成一個封閉的磁路。 即(ji)電感(gan)量處于zui大狀態(tai)下設計時(shi)。其發熱屬正(zheng)(zheng)常(chang)，但鐵(tie)心通(tong)電時(shi)不能順利(li)吸(xi)合，線(xian)圈 電感(gan)量減少(shao)，阻(zu)抗減少(shao)，電流(liu)相應增大，這樣就導(dao)致線(xian)圈電流(liu)過大，壽命(ming)受影(ying)響，所以油污使(shi)鐵(tie)心活(huo)動受阻(zu)，通(tong)電時(shi)動作(zuo)緩慢，甚(shen)至不能正(zheng)(zheng)常(chang)*被吸(xi)合，使(shi)線(xian)圈通(tong) 電時(shi)常(chang)處于阻(zu)抗較正(zheng)(zheng)常(chang)偏(pian)少(shao)的狀態(tai)，也許正(zheng)(zheng)是線(xian)圈的因素。

三，德國FESTO電(dian)磁閥線(xian)圈的好壞檢測(ce)

用萬(wan)用表量德國FESTO電(dian)(dian)磁(ci)閥(fa)(fa)的(de)電(dian)(dian)阻(zu)(zu)(zu)，線(xian)圈(quan)有電(dian)(dian)阻(zu)(zu)(zu)應該在100歐(ou)姆左右！如(ru)果線(xian)圈(quan)的(de)電(dian)(dian)阻(zu)(zu)(zu)無窮(qiong)大說明(ming)(ming)壞(huai)了(le)，還可以給(gei)電(dian)(dian)磁(ci)閥(fa)(fa)線(xian)圈(quan)通上(shang)電(dian)(dian)用鐵制(zhi)(zhi)品放在電(dian)(dian)磁(ci)閥(fa)(fa)上(shang)，因為電(dian)(dian)磁(ci)閥(fa)(fa)線(xian)圈(quan)通電(dian)(dian)后電(dian)(dian)磁(ci)閥(fa)(fa)帶磁(ci)吸住鐵制(zhi)(zhi)品。如(ru)果能吸住鐵制(zhi)(zhi)品說明(ming)(ming)線(xian)圈(quan)是好的(de)，反知說明(ming)(ming)線(xian)圈(quan)壞(huai)了(le)！

四，德國FESTO電磁閥線(xian)圈短路(lu)或斷路(lu)

檢測(ce)方(fang)法(fa)：用(yong)萬用(yong)表測(ce)量其通斷，阻值趨近于零或(huo)無窮大，那說明線(xian)圈短路或(huo)斷路。如果(guo)測(ce)量其阻值正(zheng)常（大概(gai)是(shi)(shi)(shi)幾十歐），還不能說明線(xian)圈一(yi)定是(shi)(shi)(shi)好的(de)（我有(you)一(yi)次測(ce)得一(yi)個電(dian)磁閥(fa)線(xian)圈阻值大概(gai)50歐姆，但電(dian)磁閥(fa)無法(fa)動作(zuo)，更換該線(xian)圈后一(yi)切正(zheng)常），請進行如下zui終測(ce)試(shi)：找(zhao)一(yi)個小螺絲刀(dao)放在(zai)穿(chuan)于電(dian)磁閥(fa)線(xian)圈中的(de)金屬桿的(de)附近，然后給電(dian)磁閥(fa)通電(dian)，如果(guo)感覺到有(you)磁性，那么電(dian)磁閥(fa)線(xian)圈是(shi)(shi)(shi)好的(de)，否則是(shi)(shi)(shi)壞的(de)。
