電(dian)(dian)(dian)葫(hu)(hu)蘆在電(dian)(dian)(dian)力生(sheng)產(chan)過程中使用非常廣泛，主(zhu)要用于設(she)備的(de)檢(jian)修(xiu)、吊裝、運送材料等(deng)。在使用過程中，電(dian)(dian)(dian)葫(hu)(hu)蘆發(fa)生(sheng)故(gu)障(zhang)次數也日漸(jian)增多，這不(bu)僅影響了生(sheng)產(chan)的(de)正常進行，嚴重(zhong)時將引發(fa)重(zhong)大事故(gu)，怎樣才能避免事故(gu)發(fa)生(sheng)，保證電(dian)(dian)(dian)葫(hu)(hu)蘆的(de)安全運行，及(ji)時準確(que)處理運行中出現的(de)各種故(gu)障(zhang)，已成(cheng)為生(sheng)產(chan)中的(de)重(zhong)要一環(huan)。

下面(mian)結合維修經(jing)驗(yan)，對電葫蘆一些常(chang)見故(gu)障的(de)原因進行具體分析。

1、按起動(dong)開關后電(dian)動(dong)電(dian)葫蘆不工作

主(zhu)要是因電(dian)葫(hu)蘆沒接通額定工(gong)(gong)作電(dian)壓，而(er)無法工(gong)(gong)作，一般(ban)有3種情況：

（1）供電(dian)(dian)系(xi)統是否對電(dian)(dian)動電(dian)(dian)葫(hu)蘆電(dian)(dian)源送電(dian)(dian)，一般用試(shi)電(dian)(dian)筆測試(shi)，如沒送電(dian)(dian)，等送電(dian)(dian)后(hou)再(zai)工作；

（2）電(dian)(dian)(dian)(dian)葫蘆(lu)(lu)主、控(kong)(kong)回路(lu)(lu)的(de)電(dian)(dian)(dian)(dian)器(qi)損壞(huai)、線(xian)路(lu)(lu)斷(duan)開(kai)(kai)或(huo)接觸(chu)不良，也會使電(dian)(dian)(dian)(dian)葫蘆(lu)(lu)電(dian)(dian)(dian)(dian)機無法通電(dian)(dian)(dian)(dian)，出現這種情況，需檢修(xiu)(xiu)主、控(kong)(kong)回路(lu)(lu)，檢修(xiu)(xiu)時，為了防止主、控(kong)(kong)回路(lu)(lu)送給(gei)三相(xiang)電(dian)(dian)(dian)(dian)機的(de)電(dian)(dian)(dian)(dian)源(yuan)缺相(xiang)而燒毀電(dian)(dian)(dian)(dian)機，或(huo)電(dian)(dian)(dian)(dian)葫蘆(lu)(lu)電(dian)(dian)(dian)(dian)機突(tu)然得電(dian)(dian)(dian)(dian)運轉，產生危害，一定要將(jiang)電(dian)(dian)(dian)(dian)葫蘆(lu)(lu)電(dian)(dian)(dian)(dian)機從電(dian)(dian)(dian)(dian)源(yuan)線(xian)路(lu)(lu)上斷(duan)開(kai)(kai)，只給(gei)主、控(kong)(kong)回路(lu)(lu)送電(dian)(dian)(dian)(dian)，然后點動起動和停止開(kai)(kai)關，檢查分(fen)析控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)器(qi)及線(xian)路(lu)(lu)的(de)工作情況，對有問題的(de)電(dian)(dian)(dian)(dian)器(qi)或(huo)線(xian)路(lu)(lu)進行修(xiu)(xiu)復或(huo)更換，當確認主、控(kong)(kong)回路(lu)(lu)無故障，方可重(zhong)新(xin)試車(che)；

（3）電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)比額定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)低10%以上，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)起(qi)動(dong)(dong)轉(zhuan)(zhuan)矩過小，使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)起(qi)吊不(bu)(bu)動(dong)(dong)貨(huo)(huo)物，而無(wu)法工(gong)(gong)作，檢查(cha)時(shi)，用萬用表(biao)(biao)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)等(deng)測(ce)量電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)輸入端(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，確因(yin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)過低，使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)無(wu)法起(qi)動(dong)(dong)時(shi)，需(xu)等(deng)系統電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)恢復正常后(hou)再(zai)使(shi)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)。有(you)時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)正常，而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)就是不(bu)(bu)工(gong)(gong)作，這(zhe)(zhe)需(xu)考慮其(qi)他原(yuan)因(yin)，例如：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)被燒(shao)毀，檢修(xiu)時(shi)需(xu)更(geng)換(huan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)；電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)長(chang)期不(bu)(bu)用，保(bao)養不(bu)(bu)善等(deng)原(yuan)因(yin)使(shi)制(zhi)動(dong)(dong)輪與端(duan)蓋銹(xiu)死，起(qi)動(dong)(dong)時(shi)制(zhi)動(dong)(dong)輪脫不(bu)(bu)開，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)只發出“哼(heng)”的(de)(de)響聲，轉(zhuan)(zhuan)動(dong)(dong)不(bu)(bu)起(qi)來，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)不(bu)(bu)能(neng)工(gong)(gong)作。這(zhe)(zhe)時(shi)，應卸下(xia)制(zhi)動(dong)(dong)輪，清(qing)洗銹(xiu)蝕(shi)表(biao)(biao)面，然后(hou)重(zhong)(zhong)新(xin)試(shi)車(che)；電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)嚴(yan)重(zhong)(zhong)掃膛，也(ye)會(hui)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)不(bu)(bu)轉(zhuan)(zhuan)動(dong)(dong)，發現這(zhe)(zhe)種情(qing)況，應停止使(shi)用，必(bi)須進行大修(xiu)或更(geng)換(huan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，以保(bao)證電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)正常工(gong)(gong)作。另外，生產中嚴(yan)禁超載使(shi)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)，當貨(huo)(huo)物過度超載，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)吊不(bu)(bu)動(dong)(dong)貨(huo)(huo)物，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)僅發出“哼(heng)”的(de)(de)響聲，而不(bu)(bu)運轉(zhuan)(zhuan)，嚴(yan)重(zhong)(zhong)時(shi)會(hui)燒(shao)毀電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，甚至引發事故，這(zhe)(zhe)時(shi)應立即停機(ji)(ji)(ji)，減輕(qing)貨(huo)(huo)物，使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)葫(hu)蘆(lu)(lu)(lu)在(zai)額定(ding)(ding)功率(lv)下(xia)工(gong)(gong)作。

2、電葫蘆運行時出現異(yi)常響聲

電動電葫蘆的(de)很(hen)多(duo)(duo)故(gu)(gu)障(zhang)(zhang)，例如控制電器、電機或減速器等出現的(de)故(gu)(gu)障(zhang)(zhang)，往往伴隨(sui)著異常噪聲(sheng)，這些噪聲(sheng)的(de)位(wei)置及高低(di)和音別隨(sui)故(gu)(gu)障(zhang)(zhang)原因(yin)不同而有區別，檢(jian)修(xiu)時，要多(duo)(duo)聽多(duo)(duo)看，可以利(li)用或根據故(gu)(gu)障(zhang)(zhang)響聲(sheng)特(te)點，確定(ding)發出響聲(sheng)位(wei)置，尋找和檢(jian)修(xiu)故(gu)(gu)障(zhang)(zhang)。

（1）異常噪聲發(fa)生(sheng)在控制(zhi)回路(lu)上，發(fa)出“哼(heng)”的噪聲，一般是接觸(chu)(chu)(chu)器出現(xian)了故障(zhang)（如交流接觸(chu)(chu)(chu)器觸(chu)(chu)(chu)頭接觸(chu)(chu)(chu)不良、電(dian)壓(ya)等級不符、磁芯被卡等等），應對故障(zhang)接觸(chu)(chu)(chu)器進(jin)行(xing)(xing)檢修(xiu)，無法檢修(xiu)時必須更換(huan)，處(chu)理后(hou)，噪聲自行(xing)(xing)消除。

（2）電(dian)機(ji)發(fa)出(chu)異(yi)常噪聲，應立(li)即停機(ji)，檢查(cha)電(dian)機(ji)是否單(dan)相運轉，或(huo)軸承(cheng)損壞(huai)、聯軸器軸心不(bu)(bu)正(zheng)及“掃(sao)膛”等故(gu)(gu)障，這(zhe)些(xie)都會使電(dian)機(ji)有異(yi)常響聲，不(bu)(bu)同(tong)故(gu)(gu)障的(de)響聲位置及高低和音別不(bu)(bu)同(tong)，單(dan)相運轉時(shi)(shi)，整(zheng)個電(dian)機(ji)發(fa)出(chu)有規(gui)律忽(hu)強(qiang)忽(hu)弱(ruo)的(de)“嗡(weng)(weng)嗡(weng)(weng)”聲；而軸承(cheng)損壞(huai)時(shi)(shi)，會在軸承(cheng)附近，發(fa)出(chu)伴(ban)隨(sui)著“咯噔-咯噔”的(de)“嗡(weng)(weng)嗡(weng)(weng)”聲；而聯軸器軸心不(bu)(bu)正(zheng)時(shi)(shi)，或(huo)電(dian)機(ji)輕微掃(sao)膛，整(zheng)個電(dian)機(ji)發(fa)出(chu)極高的(de)“嗡(weng)(weng)嗡(weng)(weng)”聲，并不(bu)(bu)時(shi)(shi)伴(ban)隨(sui)著尖銳刺耳(er)的(de)聲音。總之，應根據(ju)噪聲的(de)不(bu)(bu)同(tong)，找出(chu)故(gu)(gu)障，進行逐(zhu)項檢修，恢(hui)復電(dian)機(ji)正(zheng)常性(xing)能，當電(dian)機(ji)故(gu)(gu)障未(wei)處理時(shi)(shi)，禁止使用電(dian)葫蘆。

（3）異常噪聲(sheng)從減(jian)(jian)(jian)速(su)器發出，減(jian)(jian)(jian)速(su)器出現故障（如減(jian)(jian)(jian)速(su)箱(xiang)或(huo)軸(zhou)(zhou)承(cheng)缺潤滑油(you)(you)、齒輪(lun)磨損(sun)(sun)或(huo)損(sun)(sun)壞(huai)、軸(zhou)(zhou)承(cheng)損(sun)(sun)壞(huai)等等），這時應停機檢查，首先確定(ding)(ding)減(jian)(jian)(jian)速(su)器的減(jian)(jian)(jian)速(su)箱(xiang)或(huo)軸(zhou)(zhou)承(cheng)在使用前是否加了潤滑油(you)(you)，使用中是否定(ding)(ding)期更(geng)換(huan)(huan)潤滑油(you)(you)，如沒有(you)按要求(qiu)潤滑，減(jian)(jian)(jian)速(su)器不僅會(hui)產(chan)生過(guo)(guo)(guo)高的“嗡嗡”聲(sheng)，還(huan)會(hui)過(guo)(guo)(guo)度磨損(sun)(sun)或(huo)損(sun)(sun)壞(huai)齒輪(lun)及(ji)軸(zhou)(zhou)承(cheng)。為了防止故障擴大，無論減(jian)(jian)(jian)速(su)器齒輪(lun)過(guo)(guo)(guo)度磨損(sun)(sun)或(huo)損(sun)(sun)壞(huai)，還(huan)是減(jian)(jian)(jian)速(su)器軸(zhou)(zhou)承(cheng)損(sun)(sun)壞(huai)，都需要立即(ji)拆(chai)卸檢修或(huo)更(geng)換(huan)(huan)，消除故障，降低噪聲(sheng)。

3、制(zhi)動時(shi)停(ting)機下(xia)滑距(ju)離超過(guo)規定要求

電(dian)(dian)葫蘆(lu)(lu)長(chang)期停(ting)用時(shi)(shi)，有(you)(you)人誤調整(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)調整(zheng)螺母，或制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環磨(mo)損(sun)過大(da)，使(shi)(shi)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)彈簧壓力減小，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)力降低，當停(ting)機(ji)(ji)時(shi)(shi)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)不(bu)可(ke)靠，下(xia)(xia)滑(hua)距離(li)(li)超(chao)(chao)過規定要(yao)求(qiu)，這種情況(kuang)只要(yao)按(an)電(dian)(dian)葫蘆(lu)(lu)說(shuo)明書要(yao)求(qiu)，重(zhong)新調整(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)螺母即可(ke)。但(dan)工(gong)作中應(ying)注意，起升重(zhong)物時(shi)(shi)，禁止(zhi)調整(zheng)、檢查(cha)和維(wei)修制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)器(qi)(qi)。有(you)(you)時(shi)(shi)，調整(zheng)了(le)(le)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)螺母，停(ting)機(ji)(ji)下(xia)(xia)滑(hua)距離(li)(li)仍(reng)超(chao)(chao)過規定要(yao)求(qiu)，碰到此類(lei)情況(kuang)，就要(yao)考慮其(qi)他原(yuan)因，首先(xian)先(xian)拆(chai)開制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環，檢查(cha)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)面(mian)(mian)(mian)上是否粘有(you)(you)油污，如粘有(you)(you)油污，摩(mo)擦(ca)系數(shu)(shu)降低，會使(shi)(shi)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)打滑(hua)，下(xia)(xia)滑(hua)距離(li)(li)超(chao)(chao)過規定要(yao)求(qiu)，僅(jin)(jin)調整(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)螺母用處不(bu)大(da)，這時(shi)(shi)只有(you)(you)徹底清(qing)洗制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)面(mian)(mian)(mian)（清(qing)洗易用輕(qing)質汽油），恢復制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)面(mian)(mian)(mian)摩(mo)擦(ca)系數(shu)(shu)；其(qi)次，如制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環松動(dong)(dong)(dong)(dong)(dong)或損(sun)壞(huai)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環無法保證有(you)(you)效制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)，只有(you)(you)更(geng)(geng)換制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環；有(you)(you)時(shi)(shi)發現(xian)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環未損(sun)壞(huai)，僅(jin)(jin)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環與(yu)后(hou)(hou)端(duan)蓋錐面(mian)(mian)(mian)接(jie)(jie)(jie)觸(chu)不(bu)良，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)面(mian)(mian)(mian)接(jie)(jie)(jie)觸(chu)過少(shao)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)力過小，使(shi)(shi)下(xia)(xia)滑(hua)距離(li)(li)超(chao)(chao)過規定要(yao)求(qiu)，檢修時(shi)(shi)，為了(le)(le)增大(da)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)力，應(ying)查(cha)找出接(jie)(jie)(jie)觸(chu)不(bu)良的(de)位置，進行修磨(mo)，增大(da)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)時(shi)(shi)的(de)接(jie)(jie)(jie)觸(chu)面(mian)(mian)(mian)，無法修磨(mo)時(shi)(shi)，需更(geng)(geng)換配(pei)件；電(dian)(dian)葫蘆(lu)(lu)電(dian)(dian)機(ji)(ji)聯軸(zhou)器(qi)(qi)竄(cuan)動(dong)(dong)(dong)(dong)(dong)不(bu)靈或卡死，停(ting)機(ji)(ji)后(hou)(hou)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)環與(yu)后(hou)(hou)端(duan)蓋錐面(mian)(mian)(mian)接(jie)(jie)(jie)觸(chu)不(bu)良或無法接(jie)(jie)(jie)觸(chu)，使(shi)(shi)電(dian)(dian)葫蘆(lu)(lu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)效果時(shi)(shi)好時(shi)(shi)壞(huai)，這類(lei)情況(kuang)，應(ying)對聯軸(zhou)器(qi)(qi)進行檢修或更(geng)(geng)換。另外，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)器(qi)(qi)壓力彈簧長(chang)期使(shi)(shi)用產生疲勞，使(shi)(shi)彈簧力變小，停(ting)機(ji)(ji)時(shi)(shi)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)不(bu)牢固，則應(ying)更(geng)(geng)換彈簧，重(zhong)新調整(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)力。

4、電(dian)(dian)(dian)(dian)動(dong)機(ji)(ji)(ji)溫(wen)升過高首先應(ying)(ying)檢(jian)查(cha)電(dian)(dian)(dian)(dian)葫(hu)蘆是(shi)(shi)否(fou)超載使(shi)用(yong)，超載導致電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)發熱，長(chang)期超載將燒(shao)毀電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)；電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)未超載，仍發熱，應(ying)(ying)檢(jian)查(cha)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)軸承是(shi)(shi)否(fou)損壞；還(huan)應(ying)(ying)檢(jian)查(cha)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)是(shi)(shi)否(fou)按(an)規(gui)定(ding)工(gong)作(zuo)制(zhi)工(gong)作(zuo)，這也(ye)是(shi)(shi)引起電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)發熱的(de)原(yuan)因之一，使(shi)用(yong)時應(ying)(ying)嚴格按(an)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)工(gong)作(zuo)制(zhi)工(gong)作(zuo)。電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)運(yun)轉(zhuan)時，制(zhi)動(dong)器間隙太小，未完(wan)全脫開(kai)，產生很(hen)大摩(mo)擦力，摩(mo)擦發熱的(de)同時也(ye)相當于增加(jia)了附(fu)加(jia)載荷(he)，使(shi)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)轉(zhuan)速降低，電(dian)(dian)(dian)(dian)流變大而發熱，此(ci)時應(ying)(ying)停止工(gong)作(zuo)，重新調整制(zhi)動(dong)間隙。

5、重物升至半(ban)空，停(ting)車(che)后不能再起動分析其原因，首先檢查系統電壓(ya)是(shi)(shi)否過低或波動是(shi)(shi)否過大，如是(shi)(shi)這種(zhong)情(qing)況，只有等電壓(ya)恢(hui)復正常后再起動；另一方面，要(yao)(yao)注意三相電機運轉中缺(que)相，停(ting)機后無法(fa)起動，此時需要(yao)(yao)檢查電源相數。

6、不能停車或到極限位置(zhi)仍不停車

　　這(zhe)類情況一(yi)般是(shi)接(jie)觸器的(de)觸頭熔(rong)焊，當按下停(ting)(ting)(ting)止開關(guan)時，接(jie)觸器的(de)觸頭不能斷開，電(dian)機(ji)照常得電(dian)運轉，電(dian)葫蘆不停(ting)(ting)(ting)車(che)(che)；到極限位置如(ru)限位器失靈，電(dian)葫蘆不停(ting)(ting)(ting)車(che)(che)。出現(xian)這(zhe)種情況，立(li)即切斷電(dian)源，使電(dian)葫蘆強(qiang)行停(ting)(ting)(ting)車(che)(che)。停(ting)(ting)(ting)車(che)(che)后，檢修接(jie)觸器或(huo)限位器，嚴重損壞無法修復(fu)的(de)，必(bi)須更換。

7、減速(su)器(qi)漏(lou)油(you)減速(su)器(qi)漏(lou)油(you)原因是：

　　（1）減速器箱體與箱蓋(gai)之間，密(mi)(mi)封(feng)圈裝配不良或失效損壞，應拆下檢修(xiu)或更(geng)換密(mi)(mi)封(feng)圈；

　　（2）減速器連(lian)結螺釘(ding)未(wei)擰緊，在停機后，應擰緊螺釘(ding)。

　　（3）電動機掃膛(tang)

產生(sheng)掃(sao)膛的(de)(de)原因(yin)是：電(dian)(dian)機(ji)軸上支(zhi)承圈磨(mo)損嚴重、轉子(zi)鐵心位(wei)移，或因(yin)其他(ta)原因(yin)使定子(zi)鐵心位(wei)移，造成(cheng)電(dian)(dian)機(ji)錐(zhui)形轉子(zi)與定子(zi)間隙太(tai)小(xiao)發生(sheng)掃(sao)膛。電(dian)(dian)機(ji)嚴禁“掃(sao)膛”，當發生(sheng)掃(sao)膛后(hou)，應拆下支(zhi)承圈進行更(geng)換，調整定子(zi)轉子(zi)錐(zhui)面(mian)之(zhi)間的(de)(de)間隙使之(zhi)均勻，或送到維修廠進行修理(li)。通過對電(dian)(dian)動電(dian)(dian)葫蘆(lu)常見故障(zhang)及處理(li)的(de)(de)分析，使電(dian)(dian)葫蘆(lu)檢(jian)(jian)修人員(yuan)處理(li)故障(zhang)時，知道從何處著手檢(jian)(jian)查，提高了檢(jian)(jian)修效率，此外，也為(wei)操作人員(yuan)提供了現場處理(li)問題的(de)(de)方法(fa)。
