SIEMENS /西門子6RA80電機調速柜維修，故障原理分析：

1.主機轉速周期性下降

出(chu)現這種情況，大多數是(shi)因機(ji)械(xie)部分發生了故障所引起，調速電(dian)機(ji)的膠(jiao)輥(gun)比較多，每根膠(jiao)輥(gun)靠軸承來支(zhi)撐動彈。如果(guo)某根膠(jiao)輥(gun)的任何一(yi)端軸承發生了故障，都(dou)可(ke)能使主機(ji)的轉速周期性地(di)下(xia)峰(feng)，嚴重時，主機(ji)動彈會(hui)更加挫折，應當即更換軸承才(cai)行。

2.主傳動電機運轉(zhuan)不正(zheng)常，軸承發熱

主(zhu)傳動電(dian)機(ji)運轉不正(zheng)常滑(hua)(hua)差電(dian)機(ji)在(zai)運轉過(guo)程中(zhong)會劇烈振動，引起軸(zhou)承(cheng)發熱。拆開離合器電(dian)樞與磁極(ji)轉子，檢查電(dian)機(ji)的軸(zhou)承(cheng)是否嚴重(zhong)缺乏潤(run)滑(hua)(hua)油脂，而造成軸(zhou)承(cheng)嚴重(zhong)磨(mo)損，電(dian)動機(ji)的運轉性(xing)能(neng)下降。此(ci)時需要(yao)更換(huan)已(yi)損壞的軸(zhou)承(cheng)，并加注好(hao)潤(run)滑(hua)(hua)油脂。

3.主傳動電機運(yun)轉時(shi)噪聲(sheng)較大

為了調(diao)整滑(hua)差(cha)(cha)電(dian)機動(dong)平衡(heng)，其電(dian)樞和(he)磁(ci)極(ji)轉子的兩(liang)端(duan)分別裝(zhuang)有配重(zhong)裝(zhuang)置。如(ru)果這(zhe)部分裝(zhuang)置稍有松動(dong)，那么(me)滑(hua)差(cha)(cha)電(dian)機在高速(su)動(dong)彈時(shi)(shi)就會偏離原(yuan)采的位置。故障如(ru)果發(fa)生在主傳動(dong)電(dian)機的外瑞(rui)面，就會造成電(dian)樞和(he)磁(ci)極(ji)轉子的局部摩擦，使噪聲(sheng)加大。這(zhe)時(shi)(shi)就需要停機修理，恢復電(dian)樞和(he)磁(ci)極(ji)轉子的動(dong)平衡(heng)，并(bing)重(zhong)新(xin)找(zhao)好(hao)原(yuan)動(dong)平衡(heng)配重(zhong)的位置并(bing)將其固定好(hao)，使主傳動(dong)電(dian)機正常運轉。

4.調(diao)速電機升速后機速又逐漸下(xia)降以至停機

出現這(zhe)種情況，需(xu)要(yao)觀察調速電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)氣(qi)(qi)柜(ju)里的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)表(biao)指針的(de)(de)(de)變化。如果其指示電(dian)(dian)(dian)(dian)流(liu)急劇增大(da)，則(ze)主電(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)熱繼電(dian)(dian)(dian)(dian)器等過(guo)載保護(hu)裝置必然會產生保護(hu)動(dong)作，使主電(dian)(dian)(dian)(dian)機(ji)斷開三相電(dian)(dian)(dian)(dian)源而住手運轉(zhuan)。這(zhe)時需(xu)要(yao)認(ren)真(zhen)檢查主電(dian)(dian)(dian)(dian)機(ji)回路的(de)(de)(de)有(you)關接(jie)線(xian)元件及主電(dian)(dian)(dian)(dian)機(ji)的(de)(de)(de)交(jiao)流(liu)接(jie)觸(chu)(chu)器，調速電(dian)(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)(dian)氣(qi)(qi)柜(ju)里的(de)(de)(de)所有(you)熱繼電(dian)(dian)(dian)(dian)器等過(guo)載保護(hu)裝置的(de)(de)(de)接(jie)線(xian)部位(wei)是(shi)否松動(dong)，接(jie)觸(chu)(chu)是(shi)否不良而發熱。這(zhe)時需(xu)要(yao)操作人員當(dang)即采取相應措施，如清(qing)理接(jie)線(xian)端子(zi)和導(dao)線(xian)的(de)(de)(de)接(jie)觸(chu)(chu)面(mian)，緊固接(jie)線(xian)螺釘，去(qu)除燒壞了的(de)(de)(de)導(dao)線(xian)氧化物層，更(geng)換損壞嚴重的(de)(de)(de)接(jie)線(xian)端子(zi)等。
