廣元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(chu)現斷(duan)相(xiang)(xiang)時,相(xiang)(xiang)序繼(ji)電(dian)(dian)(dian)(dian)器(qi)動(dong)作(zuo)切斷(duan)a全(quan)回路,使(shi)電(dian)(dian)(dian)(dian)梯(ti)停止運行(xing)。這種故障多(duo)出(chu)在繼(ji)電(dian)(dian)(dian)(dian)器(qi)邏輯控制的電(dian)(dian)(dian)(dian)梯(ti),因為是(shi)老式電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)(kai)(kai)關(guan)多(duo)為閘刀式,電(dian)(dian)(dian)(dian)源(yuan)(yuan)經過(guo)j限開(kai)(kai)(kai)關(guan),再送至(zhi)電(dian)(dian)(dian)(dian)梯(ti)控制柜、電(dian)(dian)(dian)(dian)源(yuan)(yuan)流經的兩個開(kai)(kai)(kai)關(guan),共六根保險(xian)絲(si)。電(dian)(dian)(dian)(dian)梯(ti)運行(xing)、起動(dong),電(dian)(dian)(dian)(dian)流都很大。經過(guo)一段時間(jian)運行(xing),如(ru)維(wei)保人(ren)員不及時檢查,保險(xian)絲(si)與(yu)螺絲(si)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(ren),重(zhong)則發生(sheng)事(shi)故。
主要預防措施:
①保養人員要經(jing)常(chang)巡視(shi)檢(jian)查,發現(xian)可疑之處,及時(shi)修理(li),出現(xian)發燙(tang)、打火花諸(zhu)類情(qing)形(xing)應立即(ji)更(geng)換。
②建議用戶將閘刀開(kai)關更換為相當(dang)容量的空氣開(kai)關。
③現在設計的電(dian)梯都沒(mei)有(you)電(dian)源j限(xian)開(kai)(kai)關(guan),筆者(zhe)認為,可以(yi)就a全(quan)(quan)回路略作改動(dong),即加裝上、下(xia)j限(xian)電(dian)氣開(kai)(kai)關(guan)串聯在a全(quan)(quan)回路中,拆(chai)除原(yuan)j限(xian)開(kai)(kai)關(guan)。
2、漲繩輪開關斷開引起停梯
像曳引繩一(yi)樣,限速(su)器繩同樣會在使用(yong)過程中伸長。由于(yu)底坑漲(zhang)繩輪重錘的作用(yong),漲(zhang)繩輪開關(guan)打板偏移,直到斷(duan)開開關(guan)導(dao)致停梯。
對于電梯安裝的新裝電梯,電梯安裝人(ren)員須每月(yue)檢查一(yi)(yi)次,運行(xing)一(yi)(yi)年以后,三個月(yue)檢查一(yi)(yi)次,如此即(ji)可防患(huan)于未(wei)然。由于廳門密封不嚴,井道有(you)(you)墻洞(dong)等(deng)各(ge)種原因,老鼠竄(cuan)入井道時有(you)(you)的(de)會(hui)摔死,有(you)(you)的(de)掉入底(di)坑(keng)因想方設法逃出(chu)竄(cuan)入繩輪而(er)卡入其中(zhong),電梯向下運行(xing)導致a全鉗開(kai)關動(dong)作,有(you)(you)的(de)限速器開(kai)關也一(yi)(yi)起聯動(dong)。
