1.經(jing)常保持振動電機的清(qing)潔

振動(dong)動(dong)機(ji)在(zai)運行中，進風(feng)口周圍至少(shao)3米內不(bu)允許有(you)塵土、水漬和其他雜(za)物，以(yi)(yi)防(fang)止吸人電(dian)機(ji)內部(bu)，形(xing)成(cheng)短路(lu)介質(zhi)，或損壞導線絕(jue)緣層(ceng)，造成(cheng)匣間(jian)短路(lu)，電(dian)流增 大(da)，溫度升(sheng)高而燒毀電(dian)動(dong)機(ji)。所以(yi)(yi)，要保證(zheng)電(dian)動(dong)機(ji)有(you)足夠的絕(jue)緣電(dian)阻(zu)，以(yi)(yi)及(ji)良(liang)好的通風(feng)冷(leng)卻(que)環境，才(cai)能(neng)使電(dian)動(dong)機(ji)在(zai)長時(shi)間(jian)運行中保持安全穩(wen) 定的工(gong)作狀態。

2.保持振(zhen)動電(dian)機經(jing)常在額定電(dian)流下工作

電動(dong)機(ji)過載運(yun)行，主要(yao)(yao)原因(yin)是由于(yu)拖動(dong)的(de)負荷過大，電壓過低，或(huo)被帶動(dong)的(de)機(ji)械卡滯等造成的(de)。若過載時間過長(chang)，電動(dong)機(ji)將(jiang)從電網中吸收大量的(de)有功功率，電流便急劇增(zeng) 大，溫度(du)也隨之(zhi)上升，在(zai)高(gao)溫下電動(dong)機(ji)的(de)絕緣便老化失效而燒(shao)毀。因(yin)此，電動(dong)機(ji)在(zai)運(yun)行中，要(yao)(yao)注意(yi)經常(chang)檢查(cha)(cha)傳(chuan)動(dong)裝置(zhi)運(yun)轉(zhuan)是否靈(ling)活、可靠；連軸(zhou)器的(de)同心度(du)是否標準；齒(chi)輪傳(chuan)動(dong)的(de)靈(ling)活性等，若發現有滯卡現象(xiang)，應立即(ji)停機(ji)查(cha)(cha)明(ming)原因(yin)排(pai)除故障后再運(yun)行。

3.經(jing)常檢(jian)查電(dian)(dian)動(dong)機(ji)三相電(dian)(dian)流(liu)(liu)(liu)是否平(ping)衡(heng)三相異(yi)步電(dian)(dian)動(dong)機(ji)，其三相電(dian)(dian)流(liu)(liu)(liu)任何一相電(dian)(dian)流(liu)(liu)(liu)與(yu)其他兩相電(dian)(dian)流(liu)(liu)(liu)平(ping)均值之(zhi)差不(bu)允許(xu)超(chao)過10%，這樣才能保(bao)證(zheng)電(dian)(dian)動(dong)機(ji)安全運行(xing)。如(ru)果(guo)超(chao)過則表明(ming)(ming)電(dian)(dian)動(dong)機(ji)有故障，必須查明(ming)(ming)原因及時排除。

4.檢查(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的(de)溫(wen)度(du)要經(jing)常(chang)檢查(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)的(de)軸(zhou)(zhou)承(cheng)、定子、外殼等部位的(de)溫(wen)度(du)有(you)無(wu)異(yi)常(chang)變化，尤(you)其(qi)對(dui)無(wu)電(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)流(liu)和頻(pin)率監視及(ji)(ji)沒有(you)過載保護(hu)的(de)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)，對(dui)溫(wen)升(sheng)的(de)監視更為(wei)重(zhong)要。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)軸(zhou)(zhou)承(cheng)是(shi)否過熱(re)，缺油，若發(fa)現(xian)軸(zhou)(zhou)承(cheng)附近(jin)的(de)溫(wen)升(sheng)過高，就(jiu)應立即停機(ji)(ji)(ji)(ji)檢查(cha)。軸(zhou)(zhou)承(cheng)的(de)滾動(dong)(dong)(dong)(dong)(dong)(dong)(dong)體、滾道表(biao)面(mian)有(you)無(wu)裂紋(wen)5.觀察電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)有(you)無(wu)振(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)、噪聲和異(yi)常(chang)氣味。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)若出(chu)(chu)現(xian)振(zhen)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，會引起與(yu)之相連的(de)負載部分不同心度(du)增(zeng)高，形成(cheng)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)負載增(zeng) 大(da)，出(chu)(chu)現(xian)超負荷運行，就(jiu)會燒毀電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)。因此(ci)，電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)在運行中，尤(you)其(qi)是(shi)大(da)功(gong)率電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)更要經(jing)常(chang)檢查(cha)地腳螺栓、電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)端蓋、軸(zhou)(zhou)承(cheng)壓(ya)(ya)蓋等是(shi)否松(song)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，接地裝(zhuang)置是(shi)否可靠，發(fa)現(xian)問(wen)題及(ji)(ji)時解決。噪聲和異(yi)味是(shi)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)機(ji)(ji)(ji)(ji)運轉(zhuan)異(yi)常(chang)、隨(sui)即出(chu)(chu)現(xian)嚴重(zhong)故(gu)障的(de)前兆，必(bi)須隨(sui)時發(fa)現(xian)開查(cha)明原因而排除(chu)。
