在高空升降機的發動機沒問題的情況下,但凡啟動機或電池其中一個部件發生故障,都會使發動機難以啟動甚至無法啟動。在這種情況下,我們首先要了解如何處理高空升降機啟動機和電池,才能大致判斷出故障的位置。
如果電(dian)(dian)池已(yi)使(shi)用一(yi)年以上(shang),則(ze)應檢查(cha)電(dian)(dian)池狀(zhuang)況,很可能是電(dian)(dian)池已(yi)損壞且無法(fa)使(shi)用;如果蓄電(dian)(dian)池只使(shi)用了(le)很短的(de)時(shi)間(jian),而啟動機(ji)長期沒有檢修,那就要從起動機(ji)開始檢查(cha)了(le),然后(hou)分(fen)(fen)析和(he)處理啟動時(shi)的(de)故障現象(xiang)。詳細分(fen)(fen)析如下:
1、啟(qi)動(dong)(dong)(dong)時聽(ting)到電磁啟(qi)動(dong)(dong)(dong)開關發出“咯(ge)(ge)咯(ge)(ge)”的(de)聲音(yin),又或是啟(qi)動(dong)(dong)(dong)時啟(qi)動(dong)(dong)(dong)機會帶(dai)動(dong)(dong)(dong)曲軸慢(man)慢(man)的(de)轉幾下,然(ran)后電磁啟(qi)動(dong)(dong)(dong)開關發出“咯(ge)(ge)咯(ge)(ge)”聲,但曲軸不轉動(dong)(dong)(dong)。這(zhe)種(zhong)現象一般與(yu)電池的(de)“斷格”故障有關。
2、高空作(zuo)業(ye)平(ping)臺每次(ci)暫(zan)時(shi)停(ting)(ting)車(che)都(dou)可以(yi)再次(ci)啟動,但在(zai)長時(shi)間停(ting)(ting)車(che)或第二天啟動的情況(kuang)下(xia)曲軸只能旋(xuan)轉一下(xia)。這種(zhong)現象是電(dian)池嚴重(zhong)自(zi)放電(dian)的問題,其極(ji)板(ban)(ban)和隔(ge)板(ban)(ban)老化(hua)嚴重(zhong),說明電(dian)池可以(yi)報廢了,此時(shi)需要更換電(dian)池。
3、高空(kong)作業(ye)平臺啟(qi)動機在啟(qi)動時轉動無力,伴(ban)有橡膠(jiao)燒焦(jiao)味或電池冒煙,多為極柱(zhu)與極柱(zhu)端子接觸不良,發熱燒焦(jiao)所(suo)致。
4、如果作業車在啟(qi)(qi)動(dong)(dong)(dong)時,起動(dong)(dong)(dong)機(ji)驅(qu)動(dong)(dong)(dong)輪(lun)(lun)(lun)(lun)和發動(dong)(dong)(dong)機(ji)飛輪(lun)(lun)(lun)(lun)齒(chi)輪(lun)(lun)(lun)(lun)發出空(kong)轉(zhuan)聲,可能(neng)是(shi)以下原因(yin)造成(cheng)的: 一是(shi)飛輪(lun)(lun)(lun)(lun)齒(chi)圈嚙合(he)切面變形,二(er)是(shi)啟(qi)(qi)動(dong)(dong)(dong)機(ji)驅(qu)動(dong)(dong)(dong)輪(lun)(lun)(lun)(lun)和飛輪(lun)(lun)(lun)(lun)的齒(chi)圈間隙過大(da),如果兩者都(dou)不(bu)能(neng)嚙合(he),發動(dong)(dong)(dong)機(ji)就不(bu)能(neng)啟(qi)(qi)動(dong)(dong)(dong)。
5、一(yi)接通總開關(guan),起動(dong)(dong)機的驅(qu)動(dong)(dong)輪(lun)就與飛輪(lun)齒圈嚙(nie)合并一(yi)起轉(zhuan)動(dong)(dong),出現此類故障時(shi),一(yi)是(shi)啟動(dong)(dong)機電磁開關(guan)緊線(xian)圈接錯電源端,二是(shi)鑰匙開關(guan)3根(gen)線(xian)接錯。判斷方法是(shi):鑰匙在“0”位置時(shi)驅(qu)動(dong)(dong)啟動(dong)(dong)器,齒輪(lun)不轉(zhuan),在“2”位置時(shi),啟動(dong)(dong)發動(dong)(dong)機驅(qu)動(dong)(dong)齒與齒輪(lun)嚙(nie)合轉(zhuan)動(dong)(dong)。
6、將啟(qi)(qi)(qi)動(dong)開(kai)關(guan)撥到(dao)啟(qi)(qi)(qi)動(dong)位置(zhi)發動(dong)機無法啟(qi)(qi)(qi)動(dong)。此類故障原因(yin)可(ke)能是(shi):一(yi)是(shi)鑰匙和開(kai)關(guan)因(yin)磨損(sun)未連接到(dao)啟(qi)(qi)(qi)動(dong)電(dian)(dian)路(lu);另(ling)一(yi)種是(shi)啟(qi)(qi)(qi)動(dong)繼電(dian)(dian)器(qi)沒有連接到(dao)啟(qi)(qi)(qi)動(dong)電(dian)(dian)磁開(kai)關(guan)電(dian)(dian)路(lu)上(shang);三是(shi)電(dian)(dian)源開(kai)關(guan)沒有插入主電(dian)(dian)路(lu)。
7、啟動(dong)(dong)(dong)(dong)高(gao)空升降機時,只(zhi)有輕微的(de)“咔(ka)嗒”聲,無其他反應,這是啟動(dong)(dong)(dong)(dong)繼電(dian)器(qi)發(fa)卡造(zao)成的(de)。此時,只(zhi)需(xu)按下電(dian)磁鐵的(de)末(mo)端,迫使(shi)電(dian)磁鐵向前移動(dong)(dong)(dong)(dong),即可接通啟動(dong)(dong)(dong)(dong)電(dian)路,啟動(dong)(dong)(dong)(dong)發(fa)動(dong)(dong)(dong)(dong)機。
以(yi)上(shang)就是針對大(da)家重點關注的關于高空(kong)升降機無法啟動該怎么辦的問題的一個(ge)解(jie)答,希望能夠對大(da)家有所幫助。
