2、電葫蘆運(yun)行(xing)時出現(xian)異常響聲(sheng)

電動電葫(hu)蘆(lu)的(de)很(hen)多(duo)故障，例如控制電器(qi)、電機(ji)或減速器(qi)等出現的(de)故障，往往伴(ban)隨著(zhu)異常噪聲(sheng)(sheng)，這些噪聲(sheng)(sheng)的(de)位(wei)置(zhi)及(ji)高低和音別(bie)隨故障原因不(bu)同而有區別(bie)，檢修(xiu)時，要(yao)多(duo)聽多(duo)看，可以利用或根據(ju)故障響(xiang)聲(sheng)(sheng)特(te)點(dian)，確定發出響(xiang)聲(sheng)(sheng)位(wei)置(zhi)，尋(xun)找和檢修(xiu)故障。

（1）異常噪(zao)(zao)聲(sheng)發(fa)生在控制回路上，發(fa)出(chu)“哼”的(de)噪(zao)(zao)聲(sheng)，一(yi)般是接(jie)(jie)觸(chu)(chu)(chu)器(qi)出(chu)現了故障（如交流接(jie)(jie)觸(chu)(chu)(chu)器(qi)觸(chu)(chu)(chu)頭接(jie)(jie)觸(chu)(chu)(chu)不良(liang)、電(dian)壓等級不符、磁芯被(bei)卡(ka)等等），應對故障接(jie)(jie)觸(chu)(chu)(chu)器(qi)進行檢修(xiu)，無法檢修(xiu)時必須更換，處(chu)理后，噪(zao)(zao)聲(sheng)自行消除。

（2）電(dian)機(ji)發(fa)出(chu)異常(chang)噪(zao)聲(sheng)(sheng)，應立即停機(ji)，檢(jian)(jian)查電(dian)機(ji)是(shi)否(fou)單相運轉，或軸承損(sun)壞、聯軸器(qi)軸心(xin)不正及(ji)“掃膛”等故(gu)障(zhang)(zhang)，這些(xie)都會(hui)使電(dian)機(ji)有異常(chang)響聲(sheng)(sheng)，不同故(gu)障(zhang)(zhang)的響聲(sheng)(sheng)位置及(ji)高低和音別不同，單相運轉時(shi)(shi)，整個電(dian)機(ji)發(fa)出(chu)有規律(lv)忽強忽弱的“嗡(weng)(weng)嗡(weng)(weng)”聲(sheng)(sheng)；而軸承損(sun)壞時(shi)(shi)，會(hui)在軸承附(fu)近，發(fa)出(chu)伴(ban)隨著(zhu)(zhu)“咯(ge)噔-咯(ge)噔”的“嗡(weng)(weng)嗡(weng)(weng)”聲(sheng)(sheng)；而聯軸器(qi)軸心(xin)不正時(shi)(shi)，或電(dian)機(ji)輕微掃膛，整個電(dian)機(ji)發(fa)出(chu)極高的“嗡(weng)(weng)嗡(weng)(weng)”聲(sheng)(sheng)，并不時(shi)(shi)伴(ban)隨著(zhu)(zhu)尖銳刺(ci)耳的聲(sheng)(sheng)音。總之，應根據噪(zao)聲(sheng)(sheng)的不同，找(zhao)出(chu)故(gu)障(zhang)(zhang)，進行逐項檢(jian)(jian)修，恢(hui)復電(dian)機(ji)正常(chang)性能，當電(dian)機(ji)故(gu)障(zhang)(zhang)未處理時(shi)(shi)，禁止(zhi)使用電(dian)葫蘆。

（3）異常噪聲(sheng)從減(jian)(jian)(jian)速(su)器發(fa)出，減(jian)(jian)(jian)速(su)器出現故障（如(ru)減(jian)(jian)(jian)速(su)箱(xiang)或(huo)軸(zhou)(zhou)(zhou)承缺(que)潤(run)滑(hua)(hua)油(you)、齒(chi)輪磨(mo)損(sun)(sun)(sun)(sun)或(huo)損(sun)(sun)(sun)(sun)壞(huai)(huai)、軸(zhou)(zhou)(zhou)承損(sun)(sun)(sun)(sun)壞(huai)(huai)等等），這時應停機檢查(cha)，首先(xian)確定減(jian)(jian)(jian)速(su)器的減(jian)(jian)(jian)速(su)箱(xiang)或(huo)軸(zhou)(zhou)(zhou)承在使用前是(shi)否加了潤(run)滑(hua)(hua)油(you)，使用中(zhong)是(shi)否定期更(geng)換(huan)潤(run)滑(hua)(hua)油(you)，如(ru)沒有按要求潤(run)滑(hua)(hua)，減(jian)(jian)(jian)速(su)器不僅(jin)會產生(sheng)過高的“嗡嗡”聲(sheng)，還(huan)(huan)會過度磨(mo)損(sun)(sun)(sun)(sun)或(huo)損(sun)(sun)(sun)(sun)壞(huai)(huai)齒(chi)輪及(ji)軸(zhou)(zhou)(zhou)承。為了防止故障擴(kuo)大(da)，無論(lun)減(jian)(jian)(jian)速(su)器齒(chi)輪過度磨(mo)損(sun)(sun)(sun)(sun)或(huo)損(sun)(sun)(sun)(sun)壞(huai)(huai)，還(huan)(huan)是(shi)減(jian)(jian)(jian)速(su)器軸(zhou)(zhou)(zhou)承損(sun)(sun)(sun)(sun)壞(huai)(huai)，都需要立即(ji)拆卸檢修或(huo)更(geng)換(huan)，消除(chu)故障，降低噪聲(sheng)。

3、制動時停機下滑(hua)距離超過規定要求

電(dian)(dian)葫(hu)蘆(lu)長期停(ting)用(yong)(yong)(yong)時(shi)(shi)(shi)(shi)，有(you)人(ren)誤(wu)調(diao)(diao)(diao)整(zheng)(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)調(diao)(diao)(diao)整(zheng)(zheng)螺(luo)母(mu)，或制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環磨損過(guo)大(da)(da)，使(shi)(shi)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)彈(dan)簧(huang)壓力減小，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力降低，當停(ting)機時(shi)(shi)(shi)(shi)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)不(bu)(bu)可靠，下(xia)(xia)(xia)滑距離超過(guo)規(gui)定要(yao)(yao)求(qiu)，這(zhe)種情(qing)況(kuang)只(zhi)要(yao)(yao)按(an)電(dian)(dian)葫(hu)蘆(lu)說明書(shu)要(yao)(yao)求(qiu)，重(zhong)新(xin)調(diao)(diao)(diao)整(zheng)(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)螺(luo)母(mu)即可。但工作中應(ying)(ying)注意，起升重(zhong)物(wu)時(shi)(shi)(shi)(shi)，禁止調(diao)(diao)(diao)整(zheng)(zheng)、檢(jian)查(cha)和維修(xiu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)器。有(you)時(shi)(shi)(shi)(shi)，調(diao)(diao)(diao)整(zheng)(zheng)了制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)螺(luo)母(mu)，停(ting)機下(xia)(xia)(xia)滑距離仍超過(guo)規(gui)定要(yao)(yao)求(qiu)，碰到此類(lei)情(qing)況(kuang)，就要(yao)(yao)考慮其他原因(yin)，首先(xian)先(xian)拆開制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環，檢(jian)查(cha)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)面上是否粘有(you)油(you)(you)污(wu)，如粘有(you)油(you)(you)污(wu)，摩(mo)擦系數降低，會使(shi)(shi)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)時(shi)(shi)(shi)(shi)打滑，下(xia)(xia)(xia)滑距離超過(guo)規(gui)定要(yao)(yao)求(qiu)，僅(jin)調(diao)(diao)(diao)整(zheng)(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)螺(luo)母(mu)用(yong)(yong)(yong)處不(bu)(bu)大(da)(da)，這(zhe)時(shi)(shi)(shi)(shi)只(zhi)有(you)徹底清(qing)洗(xi)(xi)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)面（清(qing)洗(xi)(xi)易用(yong)(yong)(yong)輕質(zhi)汽油(you)(you)），恢復(fu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)面摩(mo)擦系數；其次，如制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環松(song)動(dong)(dong)(dong)(dong)(dong)(dong)或損壞，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環無法保(bao)證有(you)效制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)，只(zhi)有(you)更換制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環；有(you)時(shi)(shi)(shi)(shi)發現(xian)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環未損壞，僅(jin)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環與后端(duan)蓋(gai)錐面接(jie)(jie)觸不(bu)(bu)良(liang)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)時(shi)(shi)(shi)(shi)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)面接(jie)(jie)觸過(guo)少，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力過(guo)小，使(shi)(shi)下(xia)(xia)(xia)滑距離超過(guo)規(gui)定要(yao)(yao)求(qiu)，檢(jian)修(xiu)時(shi)(shi)(shi)(shi)，為了增(zeng)大(da)(da)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力，應(ying)(ying)查(cha)找出(chu)接(jie)(jie)觸不(bu)(bu)良(liang)的位置(zhi)，進行修(xiu)磨，增(zeng)大(da)(da)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)時(shi)(shi)(shi)(shi)的接(jie)(jie)觸面，無法修(xiu)磨時(shi)(shi)(shi)(shi)，需更換配件；電(dian)(dian)葫(hu)蘆(lu)電(dian)(dian)機聯(lian)(lian)軸器竄動(dong)(dong)(dong)(dong)(dong)(dong)不(bu)(bu)靈或卡(ka)死，停(ting)機后，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)環與后端(duan)蓋(gai)錐面接(jie)(jie)觸不(bu)(bu)良(liang)或無法接(jie)(jie)觸，使(shi)(shi)電(dian)(dian)葫(hu)蘆(lu)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)效果(guo)時(shi)(shi)(shi)(shi)好時(shi)(shi)(shi)(shi)壞，這(zhe)類(lei)情(qing)況(kuang)，應(ying)(ying)對聯(lian)(lian)軸器進行檢(jian)修(xiu)或更換。另(ling)外，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)器壓力彈(dan)簧(huang)長期使(shi)(shi)用(yong)(yong)(yong)產生疲(pi)勞，使(shi)(shi)彈(dan)簧(huang)力變小，停(ting)機時(shi)(shi)(shi)(shi)，制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)不(bu)(bu)牢固，則應(ying)(ying)更換彈(dan)簧(huang)，重(zhong)新(xin)調(diao)(diao)(diao)整(zheng)(zheng)制(zhi)(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)力。

4、電(dian)動(dong)機(ji)(ji)溫升過高首先應檢(jian)查電(dian)葫蘆(lu)是(shi)否超(chao)(chao)載(zai)(zai)使用，超(chao)(chao)載(zai)(zai)導致電(dian)機(ji)(ji)發熱，長期超(chao)(chao)載(zai)(zai)將(jiang)燒毀電(dian)機(ji)(ji)；電(dian)機(ji)(ji)未(wei)超(chao)(chao)載(zai)(zai)，仍(reng)發熱，應檢(jian)查電(dian)機(ji)(ji)軸(zhou)承是(shi)否損壞；還應檢(jian)查電(dian)機(ji)(ji)是(shi)否按規定工(gong)(gong)(gong)作制(zhi)(zhi)(zhi)工(gong)(gong)(gong)作，這也(ye)是(shi)引(yin)起(qi)電(dian)機(ji)(ji)發熱的原(yuan)因之一，使用時(shi)應嚴格(ge)按電(dian)機(ji)(ji)工(gong)(gong)(gong)作制(zhi)(zhi)(zhi)工(gong)(gong)(gong)作。電(dian)機(ji)(ji)運轉時(shi)，制(zhi)(zhi)(zhi)動(dong)器間(jian)隙(xi)(xi)太(tai)小，未(wei)完全脫(tuo)開，產生很大(da)摩擦力，摩擦發熱的同時(shi)也(ye)相當于增(zeng)加(jia)了附(fu)加(jia)載(zai)(zai)荷，使電(dian)機(ji)(ji)轉速(su)降(jiang)低，電(dian)流變大(da)而發熱，此時(shi)應停止工(gong)(gong)(gong)作，重新調整制(zhi)(zhi)(zhi)動(dong)間(jian)隙(xi)(xi)。

5、重(zhong)物升至半空，停車后不能再起(qi)(qi)動(dong)分析(xi)其(qi)原因，首先檢(jian)查(cha)系統電(dian)壓是(shi)否過低或波(bo)動(dong)是(shi)否過大，如是(shi)這種情況，只有等電(dian)壓恢(hui)復正常后再起(qi)(qi)動(dong)；另一方(fang)面，要注意三相電(dian)機運轉中缺相，停機后無法起(qi)(qi)動(dong)，此(ci)時需要檢(jian)查(cha)電(dian)源(yuan)相數。

6、不能(neng)停車(che)或到極限位(wei)置(zhi)仍不停車(che)

　　這類情況(kuang)一般是接(jie)(jie)觸(chu)器(qi)(qi)的觸(chu)頭熔焊，當按(an)下停(ting)止(zhi)開關時，接(jie)(jie)觸(chu)器(qi)(qi)的觸(chu)頭不能斷(duan)開，電(dian)機照常得(de)電(dian)運轉，電(dian)葫(hu)蘆不停(ting)車(che)；到極限位置(zhi)如(ru)限位器(qi)(qi)失靈，電(dian)葫(hu)蘆不停(ting)車(che)。出現這種(zhong)情況(kuang)，立即切斷(duan)電(dian)源，使電(dian)葫(hu)蘆強行停(ting)車(che)。停(ting)車(che)后，檢修(xiu)接(jie)(jie)觸(chu)器(qi)(qi)或限位器(qi)(qi)，嚴重損壞無法修(xiu)復(fu)的，必須更換。

7、減速器漏(lou)油減速器漏(lou)油原因是：

　　（1）減速器箱(xiang)體與(yu)箱(xiang)蓋之間，密(mi)封(feng)(feng)圈裝配不良或失效(xiao)損壞，應拆下檢修或更(geng)換密(mi)封(feng)(feng)圈；

　　（2）減速器連結螺(luo)釘未擰緊(jin)，在停機后(hou)，應擰緊(jin)螺(luo)釘。

　　（3）電動機掃膛

產生掃(sao)(sao)膛(tang)(tang)的(de)(de)原(yuan)因(yin)是(shi)：電(dian)(dian)機軸上支承(cheng)(cheng)圈(quan)磨損嚴重、轉子鐵(tie)心位移，或(huo)因(yin)其他原(yuan)因(yin)使(shi)定子鐵(tie)心位移，造(zao)成(cheng)電(dian)(dian)機錐(zhui)形轉子與(yu)定子間(jian)隙太小發生掃(sao)(sao)膛(tang)(tang)。電(dian)(dian)機嚴禁“掃(sao)(sao)膛(tang)(tang)”，當發生掃(sao)(sao)膛(tang)(tang)后，應拆下支承(cheng)(cheng)圈(quan)進(jin)行更換，調整定子轉子錐(zhui)面之(zhi)間(jian)的(de)(de)間(jian)隙使(shi)之(zhi)均勻，或(huo)送到維修(xiu)廠進(jin)行修(xiu)理。通過(guo)對電(dian)(dian)動電(dian)(dian)葫蘆常(chang)見故障及處(chu)理的(de)(de)分析，使(shi)電(dian)(dian)葫蘆檢(jian)(jian)修(xiu)人(ren)員(yuan)處(chu)理故障時，知道從何(he)處(chu)著手檢(jian)(jian)查，提(ti)高了檢(jian)(jian)修(xiu)效率，此(ci)外，也(ye)為操(cao)作人(ren)員(yuan)提(ti)供了現(xian)場處(chu)理問題的(de)(de)方法。
