畢節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
當三相(xiang)(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)出現斷(duan)相(xiang)(xiang)時,相(xiang)(xiang)序繼電(dian)(dian)(dian)(dian)器動(dong)作切斷(duan)a全(quan)回(hui)路,使電(dian)(dian)(dian)(dian)梯(ti)停止運(yun)行(xing)。這種故障(zhang)多(duo)出在(zai)繼電(dian)(dian)(dian)(dian)器邏輯控制的電(dian)(dian)(dian)(dian)梯(ti),因為是老式(shi)(shi)電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關(guan)多(duo)為閘刀式(shi)(shi),電(dian)(dian)(dian)(dian)源(yuan)(yuan)經過j限開關(guan),再(zai)送至(zhi)電(dian)(dian)(dian)(dian)梯(ti)控制柜、電(dian)(dian)(dian)(dian)源(yuan)(yuan)流(liu)經的兩個開關(guan),共六根保險(xian)絲。電(dian)(dian)(dian)(dian)梯(ti)運(yun)行(xing)、起動(dong),電(dian)(dian)(dian)(dian)流(liu)都很(hen)大(da)。經過一段時間運(yun)行(xing),如(ru)維保人員(yuan)不(bu)及時檢(jian)查,保險(xian)絲與(yu)螺絲連接處易燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)斷(duan)相(xiang)(xiang),引起停梯(ti),輕則關(guan)人,重則發(fa)生(sheng)事(shi)故。
主要預防措施:
①保養人(ren)員要經(jing)常巡視檢查,發(fa)現可疑之處,及時修理,出(chu)現發(fa)燙、打火花(hua)諸類(lei)情形應立即更換。
②建議用戶將(jiang)閘刀開關更換(huan)為相(xiang)當(dang)容量的空氣開關。
③現在設計的電(dian)梯都(dou)沒(mei)有電(dian)源j限(xian)開(kai)關,筆者認為,可以(yi)就a全回路略作改(gai)動(dong),即加裝上、下j限(xian)電(dian)氣(qi)開(kai)關串(chuan)聯在a全回路中,拆除原(yuan)j限(xian)開(kai)關。
2、漲繩輪開(kai)關斷開(kai)引起(qi)停(ting)梯
像曳引繩一樣,限(xian)速器繩同樣會在使用過程中伸長。由(you)于底坑漲(zhang)(zhang)繩輪(lun)重錘(chui)的作用,漲(zhang)(zhang)繩輪(lun)開(kai)關打(da)板偏(pian)移,直到斷(duan)開(kai)開(kai)關導(dao)致(zhi)停(ting)梯(ti)。
對于電梯安裝的新裝電梯,電梯安裝人員須每(mei)月(yue)檢(jian)查一次,運行一年以后,三(san)個月(yue)檢(jian)查一次,如此即(ji)可防(fang)患于未然。由于廳門密封不嚴,井(jing)道有墻洞等各種原因(yin),老鼠竄入(ru)井(jing)道時有的(de)會摔死,有的(de)掉入(ru)底坑因(yin)想方設法逃出竄入(ru)繩(sheng)輪(lun)而卡入(ru)其中,電梯向(xiang)下(xia)運行導致a全鉗開(kai)關動(dong)作,有的(de)限速器開(kai)關也一起聯動(dong)。
