九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(san)相電(dian)(dian)(dian)(dian)源(yuan)出現斷相時,相序(xu)繼電(dian)(dian)(dian)(dian)器動作(zuo)切斷a全回路(lu),使(shi)電(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)停(ting)止運行。這種故障多(duo)出在繼電(dian)(dian)(dian)(dian)器邏輯控制(zhi)的(de)電(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti),因(yin)為是(shi)老式電(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti),電(dian)(dian)(dian)(dian)源(yuan)開關(guan)多(duo)為閘刀式,電(dian)(dian)(dian)(dian)源(yuan)經(jing)過(guo)j限(xian)開關(guan),再(zai)送至電(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)控制(zhi)柜、電(dian)(dian)(dian)(dian)源(yuan)流經(jing)的(de)兩個開關(guan),共六根保險絲(si)。電(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)運行、起動,電(dian)(dian)(dian)(dian)流都很大。經(jing)過(guo)一段時間運行,如維保人員不及時檢查(cha),保險絲(si)與螺絲(si)連接處易燒(shao)斷,電(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)斷相,引起停(ting)梯(ti)(ti)(ti)(ti),輕則關(guan)人,重則發生事故。
主要預防措施:
①保養人員(yuan)要經常巡視檢(jian)查,發(fa)現(xian)可疑之處,及時(shi)修(xiu)理,出現(xian)發(fa)燙、打(da)火花諸類情(qing)形應立即更換。
②建議用戶(hu)將閘(zha)刀開(kai)(kai)關(guan)更換(huan)為相當容量(liang)的空氣開(kai)(kai)關(guan)。
③現在設(she)計的電(dian)(dian)梯(ti)都沒有電(dian)(dian)源(yuan)j限開(kai)關(guan),筆(bi)者認為,可以就(jiu)a全回路略作改(gai)動,即加裝上、下j限電(dian)(dian)氣(qi)開(kai)關(guan)串聯在a全回路中,拆(chai)除原j限開(kai)關(guan)。
2、漲繩輪開(kai)(kai)關斷開(kai)(kai)引(yin)起停(ting)梯(ti)
像曳引繩一(yi)樣,限速器繩同(tong)樣會(hui)在使(shi)用過程中伸長。由于(yu)底坑漲繩輪重錘的(de)作用,漲繩輪開(kai)關打板偏(pian)移,直到斷開(kai)開(kai)關導致停(ting)梯。
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,三個月(yue)檢(jian)查一次,如此即可(ke)防患于(yu)未(wei)然。由(you)于(yu)廳(ting)門密封不嚴,井(jing)道有墻洞等(deng)各種原因,老鼠(shu)竄入(ru)井(jing)道時有的會摔死,有的掉入(ru)底(di)坑因想方設法逃(tao)出竄入(ru)繩輪(lun)而卡(ka)入(ru)其(qi)中,電梯向下運行導致a全鉗開(kai)關動作,有的限速器開(kai)關也一起聯動。
