一、吊扇轉速慢的原因
吊扇轉(zhuan)速慢,首先吊(diao)(diao)扇(shan)是(shi)(shi)(shi)(shi)(shi)有(you)調速開關的,如果無論怎(zen)么調節調速開關,吊(diao)(diao)扇(shan)轉(zhuan)速都不(bu)(bu)變,那(nei)就可能是(shi)(shi)(shi)(shi)(shi)調速開關里的電(dian)(dian)阻(zu)壞了(le)。如果調速開關對吊(diao)(diao)扇(shan)轉(zhuan)速有(you)影(ying)響,但(dan)是(shi)(shi)(shi)(shi)(shi)調節到(dao)最高轉(zhuan)速,吊(diao)(diao)扇(shan)依然(ran)轉(zhuan)的很(hen)(hen)慢。有(you)以(yi)下(xia)幾種(zhong)情況,第一種(zhong)可能是(shi)(shi)(shi)(shi)(shi)電(dian)(dian)壓過(guo)低(di)的問題,但(dan)是(shi)(shi)(shi)(shi)(shi),目前(qian)我(wo)國電(dian)(dian)壓非常穩定,很(hen)(hen)少出現(xian)電(dian)(dian)壓過(guo)低(di),即使出現(xian)了(le),也(ye)會很(hen)(hen)快恢復(fu)。第二種(zhong)就是(shi)(shi)(shi)(shi)(shi)看吊(diao)(diao)扇(shan)電(dian)(dian)機(ji)是(shi)(shi)(shi)(shi)(shi)不(bu)(bu)是(shi)(shi)(shi)(shi)(shi)出現(xian)故障(zhang),可以(yi)開吊(diao)(diao)扇(shan)一段時間后(hou)關閉吊(diao)(diao)扇(shan),然(ran)后(hou)觸摸電(dian)(dian)機(ji)外殼,燙不(bu)(bu)燙手(shou)(shou),如果燙手(shou)(shou)那(nei)就是(shi)(shi)(shi)(shi)(shi)吊(diao)(diao)扇(shan)電(dian)(dian)機(ji)出現(xian)問題。第三種(zhong)就是(shi)(shi)(shi)(shi)(shi)軸承(cheng)缺油,這樣也(ye)會影(ying)響到(dao)轉(zhuan)速。第四種(zhong)可能是(shi)(shi)(shi)(shi)(shi)電(dian)(dian)容容量下(xia)降。下(xia)面具體對這些原因(yin)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(qi)。
2、軸承缺油
如果是吊扇軸(zhou)承(cheng)缺油,那(nei)可以加(jia)點黃油。如果是匝(za)間短路(lu),則(ze)會出(chu)現電機過熱的情況(kuang),則(ze)要(yao)重新繞。
如何判斷是軸承本身(shen)的問題,一(yi)是聽聲(sheng)音,噪音過大。二是找專業維修人(ren)員。
3、電壓分擔不均
這個問題檢測(ce)一般(ban)需要專業維修人員,專業的工具。
4、扇葉問題
仔細看一下扇葉是(shi)否(fou)存(cun)在問題,比(bi)如是(shi)否(fou)變(bian)形(xing)(xing),如果出(chu)現嚴(yan)重(zhong)變(bian)形(xing)(xing)的情況(kuang),也(ye)會影(ying)響(xiang)到速度(du)的。
5、電容容量下降
家用電(dian)(dian)器(qi)大(da)都是(shi)采(cai)用單相(xiang)電(dian)(dian)源供電(dian)(dian),但有(you)電(dian)(dian)動機的電(dian)(dian)器(qi),必須要有(you)兩相(xiang)或(huo)者兩相(xiang)以(yi)(yi)上的電(dian)(dian)源供電(dian)(dian)。電(dian)(dian)容(rong)(rong)(rong)容(rong)(rong)(rong)值變小或(huo)缺油摩擦大(da)或(huo)匝間(jian)短路,電(dian)(dian)容(rong)(rong)(rong)容(rong)(rong)(rong)值變小,可(ke)以(yi)(yi)適當的加大(da)電(dian)(dian)容(rong)(rong)(rong)容(rong)(rong)(rong)值,但是(shi)不能太(tai)大(da),否則(ze)電(dian)(dian)機溫度(du)升高,影響電(dian)(dian)機壽命。
6、吊扇的電機進入灰塵
吊扇用(yong)久(jiu)了(le)(le),都會或(huo)多或(huo)少(shao)的吸入些灰(hui)塵,可(ke)(ke)別(bie)小(xiao)看了(le)(le)它,它可(ke)(ke)是轉動件(jian)磨(mo)損(sun)的罪魁。當(dang)遇(yu)到(dao)這種情況,可(ke)(ke)將(jiang)電機(ji)拆(chai)下(xia),清洗。吊(diao)扇的電機(ji)很簡單,很容易(yi)拆(chai)下(xia),但(dan)注意不要(yao)破壞了(le)(le)絕緣(yuan)層,曬干或(huo)者吹(chui)干就可(ke)(ke)以了(le)(le)。
