電(dian)葫蘆在電(dian)力生(sheng)(sheng)產(chan)過程中使(shi)用(yong)(yong)非常廣泛，主(zhu)要用(yong)(yong)于設備的(de)檢修、吊裝、運(yun)送(song)材料等。在使(shi)用(yong)(yong)過程中，電(dian)葫蘆發(fa)生(sheng)(sheng)故障(zhang)(zhang)次數也日漸增多(duo)，這不僅影(ying)響(xiang)了生(sheng)(sheng)產(chan)的(de)正(zheng)常進行，嚴(yan)重時(shi)將引發(fa)重大事故，怎樣(yang)才(cai)能避免事故發(fa)生(sheng)(sheng)，保證電(dian)葫蘆的(de)安(an)全運(yun)行，及(ji)時(shi)準確處理運(yun)行中出現(xian)的(de)各種(zhong)故障(zhang)(zhang)，已(yi)成(cheng)為生(sheng)(sheng)產(chan)中的(de)重要一環。

下面結合維(wei)修經驗，對電葫蘆一些常見故障的原因進行具(ju)體分析。

1、按起動開(kai)關(guan)后電動電葫蘆不工作(zuo)

主要(yao)是因電葫(hu)蘆沒(mei)接通額(e)定工(gong)作(zuo)電壓，而無法工(gong)作(zuo)，一般有3種情(qing)況：

（1）供電系統是否對電動電葫(hu)蘆電源送(song)電，一般用試(shi)電筆測試(shi)，如(ru)沒送(song)電，等送(song)電后再工作；

（2）電(dian)(dian)(dian)葫(hu)(hu)蘆主、控(kong)回路(lu)的(de)電(dian)(dian)(dian)器損(sun)壞、線路(lu)斷開(kai)或(huo)(huo)接觸不(bu)良，也會使電(dian)(dian)(dian)葫(hu)(hu)蘆電(dian)(dian)(dian)機無法通電(dian)(dian)(dian)，出現這(zhe)種情(qing)況，需檢(jian)修主、控(kong)回路(lu)，檢(jian)修時，為(wei)了防止主、控(kong)回路(lu)送(song)給(gei)三相(xiang)電(dian)(dian)(dian)機的(de)電(dian)(dian)(dian)源缺相(xiang)而燒毀電(dian)(dian)(dian)機，或(huo)(huo)電(dian)(dian)(dian)葫(hu)(hu)蘆電(dian)(dian)(dian)機突然(ran)得電(dian)(dian)(dian)運轉，產生(sheng)危害，一定(ding)要將(jiang)電(dian)(dian)(dian)葫(hu)(hu)蘆電(dian)(dian)(dian)機從電(dian)(dian)(dian)源線路(lu)上(shang)斷開(kai)，只(zhi)給(gei)主、控(kong)回路(lu)送(song)電(dian)(dian)(dian)，然(ran)后點(dian)動起動和(he)停止開(kai)關，檢(jian)查(cha)分(fen)析控(kong)制(zhi)電(dian)(dian)(dian)器及線路(lu)的(de)工作情(qing)況，對有問(wen)題的(de)電(dian)(dian)(dian)器或(huo)(huo)線路(lu)進行修復或(huo)(huo)更換，當確(que)認(ren)主、控(kong)回路(lu)無故障，方可重(zhong)新試車；

（3）電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)電(dian)(dian)(dian)(dian)機(ji)(ji)端電(dian)(dian)(dian)(dian)壓(ya)比(bi)額定電(dian)(dian)(dian)(dian)壓(ya)低10%以上，電(dian)(dian)(dian)(dian)機(ji)(ji)起(qi)(qi)動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)矩過(guo)(guo)小，使(shi)電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)起(qi)(qi)吊不(bu)(bu)(bu)動(dong)(dong)(dong)(dong)貨物，而(er)無法工作，檢查時(shi)，用(yong)萬用(yong)表(biao)或電(dian)(dian)(dian)(dian)壓(ya)表(biao)等(deng)(deng)(deng)測量(liang)電(dian)(dian)(dian)(dian)機(ji)(ji)輸入端電(dian)(dian)(dian)(dian)壓(ya)，確(que)因電(dian)(dian)(dian)(dian)壓(ya)過(guo)(guo)低，使(shi)電(dian)(dian)(dian)(dian)機(ji)(ji)無法起(qi)(qi)動(dong)(dong)(dong)(dong)時(shi)，需等(deng)(deng)(deng)系統(tong)電(dian)(dian)(dian)(dian)壓(ya)恢復正(zheng)常(chang)后再(zai)使(shi)用(yong)電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)。有時(shi)，電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)電(dian)(dian)(dian)(dian)壓(ya)正(zheng)常(chang)，而(er)電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)就是不(bu)(bu)(bu)工作，這(zhe)需考慮其他原因，例(li)如：電(dian)(dian)(dian)(dian)機(ji)(ji)被(bei)燒(shao)毀，檢修(xiu)(xiu)時(shi)需更換電(dian)(dian)(dian)(dian)機(ji)(ji)；電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)長期(qi)不(bu)(bu)(bu)用(yong)，保(bao)養不(bu)(bu)(bu)善(shan)等(deng)(deng)(deng)原因使(shi)制(zhi)(zhi)動(dong)(dong)(dong)(dong)輪與端蓋銹死，起(qi)(qi)動(dong)(dong)(dong)(dong)時(shi)制(zhi)(zhi)動(dong)(dong)(dong)(dong)輪脫(tuo)不(bu)(bu)(bu)開，電(dian)(dian)(dian)(dian)機(ji)(ji)只發出(chu)“哼”的(de)響聲，轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)不(bu)(bu)(bu)起(qi)(qi)來，電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)不(bu)(bu)(bu)能工作。這(zhe)時(shi)，應(ying)(ying)卸下(xia)制(zhi)(zhi)動(dong)(dong)(dong)(dong)輪，清(qing)洗銹蝕(shi)表(biao)面，然后重新試車；電(dian)(dian)(dian)(dian)機(ji)(ji)嚴重掃膛，也(ye)會使(shi)電(dian)(dian)(dian)(dian)機(ji)(ji)不(bu)(bu)(bu)轉(zhuan)(zhuan)動(dong)(dong)(dong)(dong)，發現這(zhe)種情況，應(ying)(ying)停止(zhi)使(shi)用(yong)，必(bi)須進(jin)行大修(xiu)(xiu)或更換電(dian)(dian)(dian)(dian)機(ji)(ji)，以保(bao)證電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)正(zheng)常(chang)工作。另外，生產(chan)中嚴禁超載(zai)使(shi)用(yong)電(dian)(dian)(dian)(dian)動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)，當貨物過(guo)(guo)度超載(zai)，電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)吊不(bu)(bu)(bu)動(dong)(dong)(dong)(dong)貨物，電(dian)(dian)(dian)(dian)機(ji)(ji)僅(jin)發出(chu)“哼”的(de)響聲，而(er)不(bu)(bu)(bu)運轉(zhuan)(zhuan)，嚴重時(shi)會燒(shao)毀電(dian)(dian)(dian)(dian)機(ji)(ji)，甚至引發事(shi)故(gu)，這(zhe)時(shi)應(ying)(ying)立即停機(ji)(ji)，減(jian)輕貨物，使(shi)電(dian)(dian)(dian)(dian)葫(hu)(hu)(hu)(hu)(hu)蘆(lu)(lu)(lu)在(zai)額定功(gong)率下(xia)工作。

2、電葫蘆運行時出現異常響聲

電(dian)動電(dian)葫蘆的很(hen)多(duo)(duo)故障(zhang)，例如(ru)控(kong)制電(dian)器(qi)、電(dian)機或減速器(qi)等出現的故障(zhang)，往往伴(ban)隨(sui)著異常噪聲(sheng)(sheng)，這(zhe)些(xie)噪聲(sheng)(sheng)的位置(zhi)(zhi)及(ji)高(gao)低和音別隨(sui)故障(zhang)原因不同而有(you)區別，檢修時，要多(duo)(duo)聽多(duo)(duo)看，可以利用或根據故障(zhang)響聲(sheng)(sheng)特點(dian)，確定發出響聲(sheng)(sheng)位置(zhi)(zhi)，尋找和檢修故障(zhang)。

（1）異常噪聲發生(sheng)在(zai)控制回路上，發出(chu)“哼”的噪聲，一般是接觸(chu)器出(chu)現了故障(zhang)（如交流接觸(chu)器觸(chu)頭接觸(chu)不(bu)良、電壓等(deng)級不(bu)符、磁芯被卡等(deng)等(deng)），應對故障(zhang)接觸(chu)器進行檢修，無法檢修時(shi)必須(xu)更(geng)換(huan)，處(chu)理后，噪聲自行消除。

（2）電(dian)(dian)機(ji)發出異常噪聲(sheng)(sheng)，應立即停機(ji)，檢查電(dian)(dian)機(ji)是否(fou)單相運轉，或軸(zhou)承(cheng)損壞、聯軸(zhou)器(qi)軸(zhou)心不(bu)(bu)(bu)正(zheng)及(ji)“掃膛”等(deng)故(gu)障，這(zhe)些(xie)都會使(shi)電(dian)(dian)機(ji)有(you)(you)異常響(xiang)聲(sheng)(sheng)，不(bu)(bu)(bu)同故(gu)障的響(xiang)聲(sheng)(sheng)位置及(ji)高低和音別不(bu)(bu)(bu)同，單相運轉時(shi)，整個電(dian)(dian)機(ji)發出有(you)(you)規(gui)律忽(hu)強(qiang)忽(hu)弱(ruo)的“嗡(weng)嗡(weng)”聲(sheng)(sheng)；而(er)軸(zhou)承(cheng)損壞時(shi)，會在軸(zhou)承(cheng)附近，發出伴(ban)隨著(zhu)“咯噔-咯噔”的“嗡(weng)嗡(weng)”聲(sheng)(sheng)；而(er)聯軸(zhou)器(qi)軸(zhou)心不(bu)(bu)(bu)正(zheng)時(shi)，或電(dian)(dian)機(ji)輕(qing)微掃膛，整個電(dian)(dian)機(ji)發出極高的“嗡(weng)嗡(weng)”聲(sheng)(sheng)，并不(bu)(bu)(bu)時(shi)伴(ban)隨著(zhu)尖(jian)銳(rui)刺耳的聲(sheng)(sheng)音。總之(zhi)，應根據噪聲(sheng)(sheng)的不(bu)(bu)(bu)同，找出故(gu)障，進(jin)行逐項(xiang)檢修(xiu)，恢復(fu)電(dian)(dian)機(ji)正(zheng)常性能，當電(dian)(dian)機(ji)故(gu)障未處理時(shi)，禁止使(shi)用(yong)電(dian)(dian)葫蘆。

（3）異(yi)常(chang)噪聲從(cong)減(jian)(jian)(jian)(jian)速(su)(su)器(qi)(qi)發(fa)出，減(jian)(jian)(jian)(jian)速(su)(su)器(qi)(qi)出現(xian)故障（如(ru)減(jian)(jian)(jian)(jian)速(su)(su)箱或(huo)(huo)軸(zhou)承(cheng)(cheng)缺潤(run)滑(hua)(hua)油、齒(chi)輪(lun)磨(mo)損(sun)或(huo)(huo)損(sun)壞(huai)、軸(zhou)承(cheng)(cheng)損(sun)壞(huai)等(deng)等(deng)），這時應停機檢查，首先確(que)定減(jian)(jian)(jian)(jian)速(su)(su)器(qi)(qi)的(de)減(jian)(jian)(jian)(jian)速(su)(su)箱或(huo)(huo)軸(zhou)承(cheng)(cheng)在使用前是否(fou)加了潤(run)滑(hua)(hua)油，使用中是否(fou)定期更(geng)換潤(run)滑(hua)(hua)油，如(ru)沒有按要求潤(run)滑(hua)(hua)，減(jian)(jian)(jian)(jian)速(su)(su)器(qi)(qi)不僅會產生過高(gao)的(de)“嗡(weng)嗡(weng)”聲，還(huan)會過度(du)(du)磨(mo)損(sun)或(huo)(huo)損(sun)壞(huai)齒(chi)輪(lun)及軸(zhou)承(cheng)(cheng)。為(wei)了防止故障擴大(da)，無論(lun)減(jian)(jian)(jian)(jian)速(su)(su)器(qi)(qi)齒(chi)輪(lun)過度(du)(du)磨(mo)損(sun)或(huo)(huo)損(sun)壞(huai)，還(huan)是減(jian)(jian)(jian)(jian)速(su)(su)器(qi)(qi)軸(zhou)承(cheng)(cheng)損(sun)壞(huai)，都需要立即拆(chai)卸檢修(xiu)或(huo)(huo)更(geng)換，消除故障，降低噪聲。

3、制動時(shi)停機下滑距(ju)離超(chao)過規定要求
