呼和浩特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)源(yuan)(yuan)出現(xian)斷相(xiang)(xiang)時(shi),相(xiang)(xiang)序繼電(dian)(dian)(dian)器動作切斷a全(quan)回路,使電(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)停止(zhi)運行(xing)。這種故障多(duo)出在繼電(dian)(dian)(dian)器邏輯(ji)控(kong)制的電(dian)(dian)(dian)梯(ti)(ti)(ti)(ti),因(yin)為是老(lao)式電(dian)(dian)(dian)梯(ti)(ti)(ti)(ti),電(dian)(dian)(dian)源(yuan)(yuan)開關(guan)多(duo)為閘刀式,電(dian)(dian)(dian)源(yuan)(yuan)經過j限開關(guan),再送至電(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)控(kong)制柜、電(dian)(dian)(dian)源(yuan)(yuan)流經的兩個開關(guan),共(gong)六根保(bao)險絲。電(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)運行(xing)、起(qi)動,電(dian)(dian)(dian)流都很大。經過一(yi)段時(shi)間運行(xing),如維(wei)保(bao)人員不及時(shi)檢(jian)查,保(bao)險絲與螺絲連接(jie)處易燒斷,電(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)斷相(xiang)(xiang),引(yin)起(qi)停梯(ti)(ti)(ti)(ti),輕則關(guan)人,重則發生事故。
主要預防措施:
①保養人員要(yao)經常巡視(shi)檢查,發現可(ke)疑之處,及時修理,出現發燙、打火花(hua)諸類情形應立即更(geng)換(huan)。
②建議用戶將閘(zha)刀開(kai)關更換為相(xiang)當容量的空氣開(kai)關。
③現(xian)在(zai)設計(ji)的電(dian)梯都(dou)沒有(you)電(dian)源j限(xian)開(kai)關(guan),筆者(zhe)認為,可(ke)以就a全回路(lu)略作(zuo)改動,即加裝(zhuang)上、下j限(xian)電(dian)氣開(kai)關(guan)串(chuan)聯在(zai)a全回路(lu)中(zhong),拆(chai)除(chu)原j限(xian)開(kai)關(guan)。
2、漲繩輪開關(guan)斷開引起停梯
像曳(ye)引繩(sheng)一(yi)樣,限速器繩(sheng)同(tong)樣會在使用過程中伸長。由于(yu)底坑漲繩(sheng)輪重錘的(de)作(zuo)用,漲繩(sheng)輪開關打板偏移,直到斷開開關導致停(ting)梯(ti)。
對于電梯安裝的新裝電梯,電梯安裝人員須每月檢查一次,運行(xing)一年以后(hou),三個月檢查一次,如此即(ji)可防患于未然。由于廳(ting)門密封(feng)不嚴(yan),井(jing)道(dao)有(you)墻洞等各種原因,老鼠竄(cuan)入(ru)井(jing)道(dao)時有(you)的會摔死,有(you)的掉入(ru)底坑因想方設法逃出竄(cuan)入(ru)繩輪而卡(ka)入(ru)其(qi)中(zhong),電(dian)梯(ti)向下運行(xing)導致a全鉗開(kai)關動(dong)作,有(you)的限速(su)器開(kai)關也一起(qi)聯(lian)動(dong)。
