一、吊扇轉速慢的原因

吊扇轉速(su)(su)慢，首先吊(diao)(diao)(diao)扇(shan)(shan)是(shi)(shi)(shi)(shi)(shi)有調(diao)(diao)(diao)速(su)(su)開關的(de)，如果無論怎么(me)調(diao)(diao)(diao)節調(diao)(diao)(diao)速(su)(su)開關，吊(diao)(diao)(diao)扇(shan)(shan)轉速(su)(su)都不變，那就(jiu)可(ke)能(neng)是(shi)(shi)(shi)(shi)(shi)調(diao)(diao)(diao)速(su)(su)開關里的(de)電(dian)(dian)阻(zu)壞了。如果調(diao)(diao)(diao)速(su)(su)開關對(dui)吊(diao)(diao)(diao)扇(shan)(shan)轉速(su)(su)有影響(xiang)(xiang)，但是(shi)(shi)(shi)(shi)(shi)調(diao)(diao)(diao)節到最高(gao)轉速(su)(su)，吊(diao)(diao)(diao)扇(shan)(shan)依然(ran)轉的(de)很(hen)(hen)慢。有以(yi)下(xia)幾(ji)種(zhong)情況，第(di)一(yi)種(zhong)可(ke)能(neng)是(shi)(shi)(shi)(shi)(shi)電(dian)(dian)壓(ya)過低的(de)問題，但是(shi)(shi)(shi)(shi)(shi)，目前我(wo)國電(dian)(dian)壓(ya)非常穩定，很(hen)(hen)少出(chu)現(xian)(xian)電(dian)(dian)壓(ya)過低，即使出(chu)現(xian)(xian)了，也(ye)(ye)會(hui)很(hen)(hen)快恢復。第(di)二種(zhong)就(jiu)是(shi)(shi)(shi)(shi)(shi)看吊(diao)(diao)(diao)扇(shan)(shan)電(dian)(dian)機(ji)是(shi)(shi)(shi)(shi)(shi)不是(shi)(shi)(shi)(shi)(shi)出(chu)現(xian)(xian)故障，可(ke)以(yi)開吊(diao)(diao)(diao)扇(shan)(shan)一(yi)段時間(jian)后關閉吊(diao)(diao)(diao)扇(shan)(shan)，然(ran)后觸摸電(dian)(dian)機(ji)外殼，燙(tang)(tang)不燙(tang)(tang)手，如果燙(tang)(tang)手那就(jiu)是(shi)(shi)(shi)(shi)(shi)吊(diao)(diao)(diao)扇(shan)(shan)電(dian)(dian)機(ji)出(chu)現(xian)(xian)問題。第(di)三種(zhong)就(jiu)是(shi)(shi)(shi)(shi)(shi)軸承缺油，這(zhe)樣也(ye)(ye)會(hui)影響(xiang)(xiang)到轉速(su)(su)。第(di)四種(zhong)可(ke)能(neng)是(shi)(shi)(shi)(shi)(shi)電(dian)(dian)容容量下(xia)降。下(xia)面(mian)具體對(dui)這(zhe)些原因進行維修。

二、吊扇轉速慢怎么維修

1、調速器損壞

如果是新買的吊扇，就發現轉的比較慢，那可能是調速器壞了，需更換一個新的調速(su)器。

2、軸承缺油

如果(guo)(guo)是吊扇軸(zhou)承缺油，那可以加點黃油。如果(guo)(guo)是匝間短路，則會(hui)出(chu)現電(dian)機過熱的情況，則要重(zhong)新(xin)繞。

如何判斷(duan)是軸承本(ben)身(shen)的問題，一是聽聲(sheng)音(yin)，噪音(yin)過大(da)。二是找專業維修人員。

3、電壓分擔不均

這個(ge)問題檢(jian)測一般需要(yao)專業維修人員(yuan)，專業的工具。

4、扇葉問題

仔細(xi)看一下(xia)扇葉是(shi)否存在問題(ti)，比如是(shi)否變形，如果(guo)出(chu)現嚴重(zhong)變形的(de)情況，也會影響到速度的(de)。

5、電容容量下降

家(jia)用(yong)(yong)電(dian)(dian)(dian)器大(da)(da)都(dou)是采用(yong)(yong)單相(xiang)(xiang)電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)，但有電(dian)(dian)(dian)動機的(de)電(dian)(dian)(dian)器，必須要有兩(liang)相(xiang)(xiang)或者(zhe)兩(liang)相(xiang)(xiang)以上的(de)電(dian)(dian)(dian)源(yuan)供電(dian)(dian)(dian)。電(dian)(dian)(dian)容(rong)(rong)容(rong)(rong)值變小或缺油(you)摩擦(ca)大(da)(da)或匝(za)間短路，電(dian)(dian)(dian)容(rong)(rong)容(rong)(rong)值變小，可以適(shi)當的(de)加大(da)(da)電(dian)(dian)(dian)容(rong)(rong)容(rong)(rong)值，但是不能太(tai)大(da)(da)，否則電(dian)(dian)(dian)機溫度升高，影響(xiang)電(dian)(dian)(dian)機壽(shou)命。

6、吊扇的電機進入灰塵

吊扇用(yong)久(jiu)了，都會或(huo)多或(huo)少的(de)吸入些灰(hui)塵，可別(bie)小(xiao)看了它(ta)，它(ta)可是(shi)轉動件磨損的(de)罪魁。當(dang)遇(yu)到這種(zhong)情況，可將電機拆下，清洗。吊(diao)扇(shan)的(de)電機很(hen)簡(jian)單，很(hen)容易(yi)拆下，但注意不要破(po)壞了絕緣層，曬干或(huo)者吹(chui)干就可以了。
