鎮江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
當三相電(dian)(dian)(dian)源(yuan)出(chu)現斷相時(shi),相序繼電(dian)(dian)(dian)器(qi)動作切斷a全回路,使電(dian)(dian)(dian)梯(ti)停(ting)止(zhi)運行(xing)。這種故(gu)障多出(chu)在(zai)繼電(dian)(dian)(dian)器(qi)邏輯控(kong)制的(de)(de)電(dian)(dian)(dian)梯(ti),因為是老式電(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)源(yuan)開(kai)關(guan)(guan)多為閘刀式,電(dian)(dian)(dian)源(yuan)經(jing)過(guo)j限開(kai)關(guan)(guan),再送至電(dian)(dian)(dian)梯(ti)控(kong)制柜、電(dian)(dian)(dian)源(yuan)流(liu)經(jing)的(de)(de)兩個開(kai)關(guan)(guan),共(gong)六根保(bao)險絲。電(dian)(dian)(dian)梯(ti)運行(xing)、起動,電(dian)(dian)(dian)流(liu)都很(hen)大。經(jing)過(guo)一段(duan)時(shi)間運行(xing),如維保(bao)人員(yuan)不(bu)及時(shi)檢查,保(bao)險絲與(yu)螺絲連接(jie)處易燒斷,電(dian)(dian)(dian)梯(ti)斷相,引起停(ting)梯(ti),輕則關(guan)(guan)人,重則發生事故(gu)。
主要預防措施:
①保養人員要經常巡視檢查,發(fa)現可(ke)疑之(zhi)處,及時(shi)修理(li),出現發(fa)燙、打火花諸類情形應立即更換。
②建議用戶將閘刀開(kai)關更換為相當容量的空(kong)氣開(kai)關。
③現(xian)在(zai)設(she)計的電(dian)梯都沒有電(dian)源j限開(kai)關(guan)(guan),筆者認為,可以就a全回路略(lve)作改動,即加(jia)裝上、下j限電(dian)氣開(kai)關(guan)(guan)串聯在(zai)a全回路中(zhong),拆(chai)除原j限開(kai)關(guan)(guan)。
2、漲(zhang)繩輪(lun)開關斷開引起停梯
像曳引繩一樣(yang),限速器繩同(tong)樣(yang)會(hui)在使用過程中伸長。由(you)于底坑(keng)漲繩輪重錘的作用,漲繩輪開(kai)(kai)關打板偏移,直到斷開(kai)(kai)開(kai)(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)檢查一次,運行(xing)一年以后,三(san)個月(yue)檢查一次,如此即可防患于(yu)未然。由于(yu)廳門密封不(bu)嚴,井道有(you)墻洞等各(ge)種原因,老(lao)鼠竄入(ru)(ru)井道時有(you)的會摔死,有(you)的掉入(ru)(ru)底坑因想方設法逃出竄入(ru)(ru)繩輪(lun)而卡入(ru)(ru)其中,電(dian)梯向下(xia)運行(xing)導(dao)致a全鉗開(kai)關(guan)動作,有(you)的限(xian)速(su)器開(kai)關(guan)也(ye)一起聯動。
