一、啟動前(qian)的準(zhun)備和檢查

　　1、檢(jian)(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)及(ji)啟(qi)(qi)(qi)動(dong)(dong)(dong)設備接地(di)是(shi)(shi)(shi)否(fou)(fou)可(ke)(ke)靠和完整，接線(xian)是(shi)(shi)(shi)否(fou)(fou)正確(que)與良好。2、檢(jian)(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)機銘(ming)牌所示(shi)電(dian)(dian)(dian)壓、頻(pin)(pin)率與電(dian)(dian)(dian)源電(dian)(dian)(dian)壓、頻(pin)(pin)率是(shi)(shi)(shi)否(fou)(fou)相符。3、新安裝(zhuang)(zhuang)或長(chang)期停用的(de)(de)電(dian)(dian)(dian)動(dong)(dong)(dong)機啟(qi)(qi)(qi)動(dong)(dong)(dong)前應(ying)檢(jian)(jian)(jian)查(cha)(cha)繞(rao)組相對相、相對地(di)絕緣(yuan)(yuan)電(dian)(dian)(dian)阻(zu)。絕緣(yuan)(yuan)地(di)那組應(ying)大于0.5兆歐(ou)，如果低于此(ci)值，須將(jiang)繞(rao)組烘干。4、對繞(rao)線(xian)型(xing)轉(zhuan)子(zi)(zi)應(ying)檢(jian)(jian)(jian)查(cha)(cha)其(qi)集電(dian)(dian)(dian)環上的(de)(de)電(dian)(dian)(dian)刷(shua)(shua)裝(zhuang)(zhuang)置是(shi)(shi)(shi)否(fou)(fou)能(neng)(neng)正常工作，電(dian)(dian)(dian)刷(shua)(shua)壓力是(shi)(shi)(shi)否(fou)(fou)符合要(yao)求。5、檢(jian)(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)機轉(zhuan)動(dong)(dong)(dong)是(shi)(shi)(shi)否(fou)(fou)靈(ling)活，滑動(dong)(dong)(dong)軸承內的(de)(de)油是(shi)(shi)(shi)否(fou)(fou)達(da)到規定油位(wei)。6、檢(jian)(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)機所用熔斷器的(de)(de)額定電(dian)(dian)(dian)流是(shi)(shi)(shi)否(fou)(fou)符合要(yao)求。7、檢(jian)(jian)(jian)查(cha)(cha)電(dian)(dian)(dian)動(dong)(dong)(dong)機各緊(jin)固螺栓(shuan)及(ji)安裝(zhuang)(zhuang)螺栓(shuan)是(shi)(shi)(shi)否(fou)(fou)擰緊(jin)。上述各檢(jian)(jian)(jian)查(cha)(cha)全部達(da)到要(yao)求后(hou)，可(ke)(ke)啟(qi)(qi)(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)動(dong)(dong)(dong)機。電(dian)(dian)(dian)動(dong)(dong)(dong)機啟(qi)(qi)(qi)動(dong)(dong)(dong)后(hou)，空載運行(xing)30分(fen)鐘左右，注意觀察電(dian)(dian)(dian)動(dong)(dong)(dong)機是(shi)(shi)(shi)否(fou)(fou)有(you)異常現象，如發現噪聲、震動(dong)(dong)(dong)、發熱等不正常情況(kuang)，應(ying)采(cai)取(qu)措施，待情況(kuang)消(xiao)除后(hou)，才能(neng)(neng)投入運行(xing)。啟(qi)(qi)(qi)動(dong)(dong)(dong)繞(rao)線(xian)型(xing)電(dian)(dian)(dian)動(dong)(dong)(dong)機時，應(ying)將(jiang)啟(qi)(qi)(qi)動(dong)(dong)(dong)變阻(zu)器接入轉(zhuan)子(zi)(zi)電(dian)(dian)(dian)路(lu)中。對有(you)電(dian)(dian)(dian)刷(shua)(shua)提升機構的(de)(de)電(dian)(dian)(dian)動(dong)(dong)(dong)機，應(ying)放(fang)下電(dian)(dian)(dian)刷(shua)(shua)，并斷開(kai)短路(lu)裝(zhuang)(zhuang)置，合上定子(zi)(zi)電(dian)(dian)(dian)路(lu)開(kai)關，扳動(dong)(dong)(dong)變阻(zu)器。當電(dian)(dian)(dian)動(dong)(dong)(dong)機接近額定轉(zhuan)速時，提起電(dian)(dian)(dian)刷(shua)(shua)，合上短路(lu)裝(zhuang)(zhuang)置，電(dian)(dian)(dian)動(dong)(dong)(dong)機啟(qi)(qi)(qi)動(dong)(dong)(dong)完畢。

　　二、行中的維護

　　1、電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)應經常保持清(qing)潔，不(bu)允許有(you)雜物進入電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)內部(bu)；進風(feng)口和(he)出風(feng)口必(bi)須保持暢通。2、用儀表監視(shi)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、頻率及電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)負載電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、頻率要符合電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)銘牌數據，電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)負載電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不(bu)得超過銘牌上的(de)(de)規定值，否則要查(cha)明原因，采取(qu)措施，不(bu)良情(qing)況(kuang)消(xiao)除后(hou)方能繼續運行(xing)(xing)。3、采取(qu)必(bi)要手段檢(jian)測電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)各部(bu)位溫升(sheng)。4、對(dui)(dui)于繞相型轉子電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，應經常注意電(dian)(dian)(dian)(dian)(dian)(dian)刷(shua)與集電(dian)(dian)(dian)(dian)(dian)(dian)環(huan)間的(de)(de)接(jie)觸壓(ya)力、磨損及火花情(qing)況(kuang)。電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)停轉時，應斷(duan)開定子電(dian)(dian)(dian)(dian)(dian)(dian)路內的(de)(de)開關，然后(hou)將電(dian)(dian)(dian)(dian)(dian)(dian)刷(shua)提升(sheng)機(ji)(ji)(ji)構扳(ban)到啟動(dong)(dong)位置，斷(duan)開短路裝置。5、電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)運行(xing)(xing)后(hou)定期維修(xiu)(xiu)，一(yi)(yi)般分小(xiao)(xiao)修(xiu)(xiu)、大修(xiu)(xiu)兩種。小(xiao)(xiao)修(xiu)(xiu)屬一(yi)(yi)般檢(jian)修(xiu)(xiu)，對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)啟動(dong)(dong)設備及整體不(bu)作大的(de)(de)拆卸，約一(yi)(yi)季度一(yi)(yi)次(ci)，大修(xiu)(xiu)要將所有(you)傳動(dong)(dong)裝置及電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)所有(you)零部(bu)件都拆卸下來，并將拆卸的(de)(de)零部(bu)件作全面的(de)(de)檢(jian)查(cha)及清(qing)洗(xi)，一(yi)(yi)般一(yi)(yi)年(nian)一(yi)(yi)次(ci)。
