白山電梯維修保養人員的工作內容
隨著科技的進步,電梯技術水平不斷提高,其運行的可靠性明顯加大。在維修保養中,一些比較典型的停梯故障需要及時排出。
1、斷相引起停梯
當(dang)三相電(dian)(dian)(dian)(dian)源(yuan)出(chu)現斷(duan)相時,相序(xu)繼電(dian)(dian)(dian)(dian)器動(dong)作切斷(duan)a全(quan)回路,使(shi)電(dian)(dian)(dian)(dian)梯(ti)停止(zhi)運(yun)行(xing)。這種(zhong)故障多(duo)出(chu)在繼電(dian)(dian)(dian)(dian)器邏輯控制(zhi)的電(dian)(dian)(dian)(dian)梯(ti),因為(wei)是老式(shi)電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源(yuan)開(kai)關多(duo)為(wei)閘刀式(shi),電(dian)(dian)(dian)(dian)源(yuan)經(jing)過(guo)j限開(kai)關,再送(song)至電(dian)(dian)(dian)(dian)梯(ti)控制(zhi)柜、電(dian)(dian)(dian)(dian)源(yuan)流經(jing)的兩個開(kai)關,共(gong)六根(gen)保(bao)(bao)險絲(si)。電(dian)(dian)(dian)(dian)梯(ti)運(yun)行(xing)、起動(dong),電(dian)(dian)(dian)(dian)流都很大。經(jing)過(guo)一段(duan)時間(jian)運(yun)行(xing),如維(wei)保(bao)(bao)人(ren)員不(bu)及時檢查,保(bao)(bao)險絲(si)與螺絲(si)連接處易燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)斷(duan)相,引(yin)起停梯(ti),輕(qing)則關人(ren),重則發生事(shi)故。
主要預防措施:
①保養人員(yuan)要經常巡(xun)視檢查,發(fa)現可疑之(zhi)處,及時修(xiu)理,出現發(fa)燙、打火花諸類情形應立即(ji)更換。
②建議用戶將閘刀(dao)開(kai)關(guan)更換為相當容量的空(kong)氣開(kai)關(guan)。
③現在設(she)計的電(dian)梯都(dou)沒有電(dian)源j限(xian)開(kai)關,筆(bi)者認為,可以就(jiu)a全回(hui)路略作改(gai)動,即(ji)加裝上、下j限(xian)電(dian)氣開(kai)關串聯在a全回(hui)路中,拆除原j限(xian)開(kai)關。
2、漲繩輪開關斷開引起停梯(ti)
像曳引繩(sheng)(sheng)一樣(yang),限速器繩(sheng)(sheng)同樣(yang)會(hui)在使用(yong)過程中伸長。由于底坑(keng)漲(zhang)繩(sheng)(sheng)輪重(zhong)錘(chui)的作用(yong),漲(zhang)繩(sheng)(sheng)輪開(kai)關打板偏移(yi),直到斷(duan)開(kai)開(kai)關導致停梯。
對于電梯安裝的新裝電梯,電梯安裝人員須每月(yue)(yue)檢查(cha)(cha)一(yi)次(ci),運行一(yi)年以后,三個(ge)月(yue)(yue)檢查(cha)(cha)一(yi)次(ci),如此即可防患于未然。由于廳門密(mi)封(feng)不嚴,井道有墻洞等各種原因(yin),老鼠竄入井道時有的(de)會摔死,有的(de)掉入底坑因(yin)想方設法逃出(chu)竄入繩輪而(er)卡入其中(zhong),電(dian)梯向下運行導致a全(quan)鉗開(kai)關動(dong)作,有的(de)限速器開(kai)關也一(yi)起聯動(dong)。
