保亭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)(yuan)(yuan)出(chu)現斷(duan)相時,相序繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)動(dong)(dong)作切斷(duan)a全回路(lu),使(shi)電(dian)(dian)(dian)(dian)梯(ti)(ti)停止(zhi)運行。這種故(gu)障多出(chu)在繼(ji)(ji)電(dian)(dian)(dian)(dian)器(qi)邏輯控(kong)制的電(dian)(dian)(dian)(dian)梯(ti)(ti),因(yin)為是老式(shi)電(dian)(dian)(dian)(dian)梯(ti)(ti),電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關多為閘刀式(shi),電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)經(jing)(jing)過j限開關,再送至電(dian)(dian)(dian)(dian)梯(ti)(ti)控(kong)制柜、電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)流經(jing)(jing)的兩個開關,共六(liu)根保(bao)險絲(si)(si)。電(dian)(dian)(dian)(dian)梯(ti)(ti)運行、起(qi)(qi)動(dong)(dong),電(dian)(dian)(dian)(dian)流都很大。經(jing)(jing)過一段時間運行,如(ru)維(wei)保(bao)人(ren)員不及時檢(jian)查(cha),保(bao)險絲(si)(si)與螺絲(si)(si)連接處易(yi)燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)(ti)斷(duan)相,引起(qi)(qi)停梯(ti)(ti),輕則(ze)關人(ren),重則(ze)發(fa)生事故(gu)。
主要預防措施:
①保養(yang)人員要經常巡視檢查(cha),發現可(ke)疑之(zhi)處,及時修理,出現發燙、打火花諸類(lei)情形應立即更換(huan)。
②建議用戶(hu)將閘刀開關(guan)更換為相當容量的(de)空(kong)氣開關(guan)。
③現(xian)在設計的(de)電梯都沒有電源j限開關(guan),筆(bi)者認(ren)為,可(ke)以就a全回(hui)(hui)路略作改動,即加裝上、下j限電氣(qi)開關(guan)串聯在a全回(hui)(hui)路中,拆(chai)除原j限開關(guan)。
2、漲繩輪(lun)開關斷開引(yin)起停(ting)梯(ti)
像曳引繩(sheng)(sheng)一樣(yang),限速器繩(sheng)(sheng)同樣(yang)會在使用過程中伸長。由于底坑漲(zhang)繩(sheng)(sheng)輪重錘的作(zuo)用,漲(zhang)繩(sheng)(sheng)輪開(kai)關打板偏(pian)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(xu)每月檢(jian)查(cha)一(yi)次(ci),運(yun)行(xing)一(yi)年以后,三(san)個月檢(jian)查(cha)一(yi)次(ci),如此即(ji)可(ke)防患于(yu)未然。由于(yu)廳門密封不嚴,井道有墻洞(dong)等各(ge)種原因,老鼠竄入(ru)(ru)井道時有的(de)會摔死,有的(de)掉入(ru)(ru)底坑因想方設法(fa)逃出竄入(ru)(ru)繩輪而卡入(ru)(ru)其中,電梯(ti)向下運(yun)行(xing)導致a全鉗開關動(dong)作(zuo),有的(de)限(xian)速器(qi)開關也一(yi)起(qi)聯動(dong)。
