廈門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)(dian)源(yuan)出(chu)現斷(duan)相(xiang)時,相(xiang)序繼(ji)電(dian)(dian)(dian)(dian)器(qi)動作切斷(duan)a全回路,使電(dian)(dian)(dian)(dian)梯(ti)停止(zhi)運行(xing)。這(zhe)種故(gu)障多出(chu)在繼(ji)電(dian)(dian)(dian)(dian)器(qi)邏輯(ji)控(kong)(kong)制的電(dian)(dian)(dian)(dian)梯(ti),因為(wei)是老式電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源(yuan)開關(guan)多為(wei)閘刀式,電(dian)(dian)(dian)(dian)源(yuan)經過j限開關(guan),再送至電(dian)(dian)(dian)(dian)梯(ti)控(kong)(kong)制柜(ju)、電(dian)(dian)(dian)(dian)源(yuan)流經的兩個開關(guan),共六根保險絲。電(dian)(dian)(dian)(dian)梯(ti)運行(xing)、起(qi)動,電(dian)(dian)(dian)(dian)流都很大。經過一(yi)段時間運行(xing),如(ru)維保人(ren)(ren)員不及時檢查,保險絲與螺絲連接處易燒(shao)斷(duan),電(dian)(dian)(dian)(dian)梯(ti)斷(duan)相(xiang),引起(qi)停梯(ti),輕則關(guan)人(ren)(ren),重(zhong)則發生事故(gu)。
主要預防措施:
①保(bao)養人員要經常巡(xun)視檢查,發(fa)現可(ke)疑之(zhi)處,及(ji)時修理(li),出現發(fa)燙、打火花(hua)諸類(lei)情形應立即更(geng)換。
②建議用戶(hu)將閘刀開關更換為相當容(rong)量(liang)的空(kong)氣開關。
③現(xian)在設計的電(dian)梯(ti)都沒有電(dian)源(yuan)j限開(kai)關(guan),筆者認(ren)為,可(ke)以就a全(quan)回(hui)路略作(zuo)改動,即加裝(zhuang)上、下j限電(dian)氣開(kai)關(guan)串(chuan)聯在a全(quan)回(hui)路中,拆除原j限開(kai)關(guan)。
2、漲繩輪開關(guan)斷開引起停梯(ti)
像曳引繩一樣(yang),限速器繩同(tong)樣(yang)會在使(shi)用過程(cheng)中(zhong)伸長。由于(yu)底(di)坑(keng)漲繩輪(lun)重錘的作用,漲繩輪(lun)開關(guan)打板偏移,直到(dao)斷開開關(guan)導致停梯。
對于電梯安裝的新裝電梯,電梯安裝人(ren)員須(xu)每(mei)月檢查(cha)(cha)一(yi)次(ci),運(yun)行(xing)一(yi)年以后,三個月檢查(cha)(cha)一(yi)次(ci),如(ru)此(ci)即可防患(huan)于(yu)未然。由(you)于(yu)廳門密封(feng)不嚴,井(jing)道(dao)有(you)(you)墻洞等各種原(yuan)因,老鼠(shu)竄入(ru)井(jing)道(dao)時有(you)(you)的(de)(de)會(hui)摔死,有(you)(you)的(de)(de)掉入(ru)底坑因想方設(she)法逃出竄入(ru)繩輪而卡入(ru)其中,電梯向下運(yun)行(xing)導致a全鉗開關(guan)動作,有(you)(you)的(de)(de)限速器開關(guan)也一(yi)起聯(lian)動。
