在使用電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)前需先了解其使用的電(dian)(dian)(dian)(dian)(dian)(dian)源是(shi)(shi)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)還(huan)(huan)是(shi)(shi)交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，如果是(shi)(shi)交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，還(huan)(huan)需知道它是(shi)(shi)三相還(huan)(huan)是(shi)(shi)單(dan)相的交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，接錯(cuo)電(dian)(dian)(dian)(dian)(dian)(dian)源會導致(zhi)不必要(yao)的損失和危(wei)險。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)轉動(dong)(dong)后若沒(mei)有接負載或(huo)負載很(hen)輕使得電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)轉速快，則感應電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)勢較(jiao)強(qiang)，此(ci)時電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)兩端電(dian)(dian)(dian)(dian)(dian)(dian)壓為{？}，軸(zhou)流(liu)YT電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)，電(dian)(dian)(dian)(dian)(dian)(dian)源提供電(dian)(dian)(dian)(dian)(dian)(dian)壓減去感應電(dian)(dian)(dian)(dian)(dian)(dian)壓，YT電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)生產(chan)廠家，因此(ci)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)減弱。

若電(dian)動機(ji)的負載很(hen)重，YT電(dian)機(ji)，轉速慢則相對感應電(dian)動勢較小，也因此(ci)電(dian)源需提供較大(da)電(dian)流（功(gong)(gong)率）以對應所(suo)需的較大(da)功(gong)(gong)率來輸出／作功(gong)(gong)。

YT電機進(jin)行技術(shu)改造

YT電(dian)(dian)機(ji)設(she)備管理(li)部電(dian)(dian)氣一次電(dian)(dian)機(ji)班在對#1機(ji)組鍋爐(lu)A、B一風機(ji)電(dian)(dian)機(ji)檢(jian)修時，發(fa)現電(dian)(dian)機(ji)轉子軸與軸瓦相接觸的(de)(de)部位有輕(qing)微爬行(xing)現象(xiang)，經過相關技(ji)術人員的(de)(de)分(fen)析(xi)判斷，為軸電(dian)(dian)流所致，該(gai)現象(xiang)嚴重時會使(shi)軸和(he)軸瓦受到損壞(huai)，縮短電(dian)(dian)機(ji)的(de)(de)使(shi)用壽命。

通過多次檢驗測試后，他們采(cai)取了在非驅(qu)動(dong)端(duan)的(de)(de)軸(zhou)(zhou)承座和軸(zhou)(zhou)承支(zhi)架處(chu)加絕緣(yuan)隔板、切(qie)斷軸(zhou)(zhou)電(dian)(dian)流回路，同(tong)時，在電(dian)(dian)機(ji)(ji)驅(qu)動(dong)端(duan)加裝(zhuang)了一(yi)組軸(zhou)(zhou)接地碳(tan)刷，采(cai)用恒(heng)壓彈簧使接地碳(tan)刷可靠接地，保證轉軸(zhou)(zhou)電(dian)(dian)位為零(ling)電(dian)(dian)位，以(yi)此消除軸(zhou)(zhou)電(dian)(dian)流。該接地裝(zhuang)置結構(gou)簡單，具有(you)良(liang)好的(de)(de)接地效果(guo)和可靠性，有(you)效防范高壓電(dian)(dian)動(dong)機(ji)(ji)軸(zhou)(zhou)電(dian)(dian)流，大大降低檢修維護成本(ben)，提(ti)高電(dian)(dian)機(ji)(ji)運行的(de)(de)可靠性。

風機風機震動大是什么原因？

1 風機的(de)(de)葉(xie)輪的(de)(de)動，靜平(ping)衡不(bu)(bu)合格，含風機使用一定時間后葉(xie)輪的(de)(de)不(bu)(bu)均勻磨損(sun)線引(yin)起平(ping)衡不(bu)(bu)好，

3 風機與電機的軸的同軸度不(bu)合格(ge)，

4 葉(xie)(xie)輪(lun)本(ben)身結構不合理，如葉(xie)(xie)片個數成偶數等，

5 風機與(yu)電機間如對(dui)(dui)輪聯接時，對(dui)(dui)輪間隙過小，

6 風機出入口管道(dao)設計不合理(li)，引(yin)起(qi)共振，

7 風機入口氣(qi)源不穩定引(yin)起風機喘振。
