襄陽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)電(dian)(dian)(dian)源(yuan)出現斷(duan)相(xiang)時,相(xiang)序繼(ji)電(dian)(dian)(dian)器動(dong)作切斷(duan)a全(quan)回路,使電(dian)(dian)(dian)梯(ti)(ti)停(ting)(ting)止運(yun)(yun)行。這種故(gu)障多出在繼(ji)電(dian)(dian)(dian)器邏輯控制的電(dian)(dian)(dian)梯(ti)(ti),因為是老(lao)式電(dian)(dian)(dian)梯(ti)(ti),電(dian)(dian)(dian)源(yuan)開關多為閘(zha)刀式,電(dian)(dian)(dian)源(yuan)經(jing)(jing)過j限開關,再送至電(dian)(dian)(dian)梯(ti)(ti)控制柜(ju)、電(dian)(dian)(dian)源(yuan)流(liu)經(jing)(jing)的兩個開關,共六根(gen)保(bao)險(xian)絲(si)。電(dian)(dian)(dian)梯(ti)(ti)運(yun)(yun)行、起(qi)動(dong),電(dian)(dian)(dian)流(liu)都很大。經(jing)(jing)過一(yi)段時間運(yun)(yun)行,如維保(bao)人員不及時檢查,保(bao)險(xian)絲(si)與螺絲(si)連接處易(yi)燒斷(duan),電(dian)(dian)(dian)梯(ti)(ti)斷(duan)相(xiang),引起(qi)停(ting)(ting)梯(ti)(ti),輕(qing)則關人,重則發生事故(gu)。
主要預防措施:
①保養人員(yuan)要經常(chang)巡視檢查(cha),發(fa)現(xian)可疑之(zhi)處(chu),及時(shi)修理,出(chu)現(xian)發(fa)燙、打火花諸類情形應立即更換。
②建議用(yong)戶(hu)將(jiang)閘刀(dao)開關更(geng)換為相當容量的空氣開關。
③現(xian)在(zai)設計的電梯都沒有電源j限開(kai)關(guan),筆者(zhe)認為,可以就a全回路(lu)略(lve)作改動,即(ji)加裝上(shang)、下j限電氣開(kai)關(guan)串聯在(zai)a全回路(lu)中,拆除原(yuan)j限開(kai)關(guan)。
2、漲繩輪開(kai)關斷開(kai)引起停梯(ti)
像曳引繩(sheng)一(yi)樣,限速器繩(sheng)同(tong)樣會(hui)在使用(yong)過程中(zhong)伸長。由(you)于(yu)底坑(keng)漲繩(sheng)輪(lun)重錘(chui)的作用(yong),漲繩(sheng)輪(lun)開(kai)關打板偏移,直(zhi)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(yuan)須每月檢(jian)查一次(ci),運行一年以(yi)后(hou),三(san)個月檢(jian)查一次(ci),如此即可防患于未然。由于廳門密(mi)封不(bu)嚴,井道(dao)有(you)(you)墻洞等各種原因,老鼠竄入(ru)井道(dao)時有(you)(you)的會摔死,有(you)(you)的掉入(ru)底坑因想方設法(fa)逃出竄入(ru)繩輪而(er)卡入(ru)其(qi)中(zhong),電梯向下運行導(dao)致a全鉗(qian)開關(guan)動作,有(you)(you)的限速(su)器(qi)開關(guan)也一起聯動。
