電動叉車長時(shi)間使用后會出(chu)現(xian)電力系統故(gu)障，主要(yao)有(you)不充(chong)電、充(chong)電電壓過低以及(ji)充(chong)電電壓過高這(zhe)(zhe)三類(lei)(lei)問題(ti)。那么這(zhe)(zhe)三類(lei)(lei)問題(ti)出(chu)現(xian)時(shi)會有(you)哪(na)些(xie)癥狀(zhuang)呢？又是哪(na)些(xie)原(yuan)因引起的呢？小(xiao)編總結了這(zhe)(zhe)些(xie)問題(ti)供您參考(kao)。

1、不充電

故(gu)障現(xian)象：電(dian)(dian)(dian)動(dong)叉車發(fa)動(dong)機正常工作時充(chong)電(dian)(dian)(dian)指(zhi)示(shi)(shi)燈亮或電(dian)(dian)(dian)流表指(zhi)示(shi)(shi)負值方向(xiang)，說明發(fa)電(dian)(dian)(dian)機不發(fa)電(dian)(dian)(dian)，蓄電(dian)(dian)(dian)池不充(chong)電(dian)(dian)(dian)。

故(gu)障(zhang)(zhang)(zhang)原因：發電(dian)機(ji)故(gu)障(zhang)(zhang)(zhang)、調節(jie)器故(gu)障(zhang)(zhang)(zhang)或電(dian)氣線路(lu)故(gu)障(zhang)(zhang)(zhang)等。

2、電動叉車充電電壓(ya)過低

故(gu)障(zhang)現象：發動(dong)機(ji)工(gong)作過程(cheng)中，充(chong)電(dian)指示燈閃爍或(huo)電(dian)流(liu)表在零(ling)位(wei)左(zuo)右擺動(dong)，使用萬(wan)用表的(de)直流(liu)電(dian)壓(ya)檔測量(liang)蓄(xu)電(dian)池或(huo)發電(dian)機(ji)兩端的(de)電(dian)壓(ya)值，如低于標準值，則表明(ming)充(chong)電(dian)電(dian)壓(ya)過低。

故障原因：調節器工作電壓失(shi)調或有(you)故障，傳動(dong)帶過松(song)，發(fa)電機內部定子、整(zheng)流器、轉子等部件(jian)有(you)故障。

3、充電電壓過高

故障現象(xiang)：電(dian)(dian)(dian)動叉車(che)發動機工作(zuo)過程中燈泡(pao)易(yi)燒(shao)毀(hui)，蓄電(dian)(dian)(dian)池電(dian)(dian)(dian)解液消耗過快，使用(yong)萬(wan)用(yong)表(biao)的直流(liu)電(dian)(dian)(dian)壓檔測量蓄電(dian)(dian)(dian)池或發電(dian)(dian)(dian)機兩(liang)端(duan)的電(dian)(dian)(dian)壓值，如(ru)高于標(biao)準值，則表(biao)明充電(dian)(dian)(dian)電(dian)(dian)(dian)壓過高。

故障原因(yin)：調節器工作電壓失調或(huo)有故障。

人(ren)(ren)們在(zai)使(shi)用(yong)電(dian)動(dong)(dong)叉車時可能會遇到電(dian)動(dong)(dong)叉車出現這樣的故(gu)障，人(ren)(ren)們在(zai)遇到故(gu)障時可以按照以上的原因及(ji)時排查，如(ru)果自己不能解決的可以請專業的維(wei)修(xiu)人(ren)(ren)員來上門解決。
