冷卻塔電機不轉維修

　　冷卻塔風機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)不轉(zhuan)(zhuan)的(de)(de)(de)(de)原(yuan)因(yin)主要(yao)(yao)有：繞(rao)組斷(duan)(duan)路、缺油(you)(you)抱軸(zhou)(zhou)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)異常(chang)等(deng)。從對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)的(de)(de)(de)(de)維修(xiu)實(shi)踐(jian)來看(kan)，后(hou)兩種故障居多。對(dui)(dui)于不轉(zhuan)(zhuan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)，我(wo)的(de)(de)(de)(de) 維修(xiu)步(bu)驟是(shi)(shi)(shi)，測(ce)插頭、轉(zhuan)(zhuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)、量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)、再(zai)處理(li)。 第一步(bu)，測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)運行和(he)(he)調(diao)速(su)繞(rao)組。先把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)定時(shi)(shi)器(qi)(qi)旋轉(zhuan)(zhuan)一下，當聽到(dao)有嗒(da)(da)嗒(da)(da)聲時(shi)(shi)，說明(ming)定時(shi)(shi)器(qi)(qi)是(shi)(shi)(shi)正(zheng)常(chang)的(de)(de)(de)(de)。如(ru)(ru)果(guo)沒有嗒(da)(da)嗒(da)(da)聲，說明(ming)定時(shi)(shi)器(qi)(qi) 損(sun)(sun)壞。如(ru)(ru)果(guo)無(wu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值，可(ke)(ke)能(neng)是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)繞(rao)組燒毀斷(duan)(duan)路。對(dui)(dui)串有熱熔(rong)斷(duan)(duan)器(qi)(qi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)，可(ke)(ke)能(neng)是(shi)(shi)(shi)熱熔(rong)斷(duan)(duan)器(qi)(qi)開(kai)(kai)(kai)路，還應拆(chai)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)看(kan)一看(kan)，如(ru)(ru)果(guo)只是(shi)(shi)(shi)開(kai)(kai)(kai)路，短接 熱熔(rong)斷(duan)(duan)器(qi)(qi)即(ji)可(ke)(ke)恢復正(zheng)常(chang)。檔位(wei)開(kai)(kai)(kai)關(guan)(guan)全(quan)部(bu)損(sun)(sun)壞，但可(ke)(ke)能(neng)性不大。 第二步(bu)，檢查(cha)是(shi)(shi)(shi)否抱軸(zhou)(zhou)，拆(chai)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)護罩，用(yong)(yong)手旋動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)，如(ru)(ru)果(guo)轉(zhuan)(zhuan)不動(dong)(dong)(dong)，說明(ming)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)抱軸(zhou)(zhou)嚴(yan)重。拆(chai)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)，先清除(chu)前后(hou)軸(zhou)(zhou)套(tao)和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)上(shang)(shang)(shang)的(de)(de)(de)(de)油(you)(you)污 、銹跡(ji)，然后(hou)在(zai)(zai)(zai)前后(hou)軸(zhou)(zhou)套(tao)的(de)(de)(de)(de)油(you)(you)氈(zhan)上(shang)(shang)(shang)加足縫(feng)紉機(ji)(ji)(ji)(ji)(ji)油(you)(you)，大部(bu)分電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)都能(neng)排(pai)除(chu)故障。 第三步(bu)，測(ce)量(liang)(liang)啟(qi)(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)，如(ru)(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)軸(zhou)(zhou)旋轉(zhuan)(zhuan)靈活，就要(yao)(yao)測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)(de)啟(qi)(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)。首先，用(yong)(yong)萬用(yong)(yong)表R×100Ω檔，測(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)啟(qi)(qi)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)兩端(duan)，整個 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)運行、啟(qi)(qi)動(dong)(dong)(dong)和(he)(he)調(diao)速(su)繞(rao)組的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值，即(ji)黑色和(he)(he)**引(yin)線(xian)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值。 能(neng)動(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)的(de)(de)(de)(de)維修(xiu) 對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)能(neng)動(dong)(dong)(dong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)，我(wo)是(shi)(shi)(shi)根據實(shi)際(ji)情況，一步(bu) 到(dao)位(wei)。而不是(shi)(shi)(shi)象(xiang)上(shang)(shang)(shang)述那樣，按部(bu)就班(ban)地(di)進(jin)行維修(xiu)。如(ru)(ru)果(guo)用(yong)(yong)戶說，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)先慢慢轉(zhuan)(zhuan)，然后(hou)漸漸變快。根據經驗，一般是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)輕微抱軸(zhou)(zhou)。原(yuan)因(yin)是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian) 風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)潤滑油(you)(you)初期缺失。直接拆(chai)開(kai)(kai)(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)，在(zai)(zai)(zai)前后(hou)軸(zhou)(zhou)套(tao)的(de)(de)(de)(de)油(you)(you)氈(zhan)上(shang)(shang)(shang)加足縫(feng)紉機(ji)(ji)(ji)(ji)(ji)油(you)(you)，一般即(ji)可(ke)(ke)修(xiu)復。 遙控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)扇(shan)(shan)(shan)，上(shang)(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)就轉(zhuan)(zhuan)故障的(de)(de)(de)(de)排(pai)除(chu) 現在(zai)(zai)(zai)的(de)(de)(de)(de)遙 控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)扇(shan)(shan)(shan)控(kong)制執行元件基(ji)本上(shang)(shang)(shang)都是(shi)(shi)(shi)可(ke)(ke)控(kong)硅。從原(yuan)理(li)可(ke)(ke)知可(ke)(ke)控(kong)硅實(shi)質等(deng)同于開(kai)(kai)(kai)關(guan)(guan)可(ke)(ke)控(kong)硅擊穿等(deng)同于開(kai)(kai)(kai)關(guan)(guan)接通。接通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)風(feng)(feng)(feng)(feng)(feng)(feng)扇(shan)(shan)(shan)當然就轉(zhuan)(zhuan)了。 如(ru)(ru)一臺
