鶴崗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)源出現斷(duan)(duan)相(xiang)時,相(xiang)序繼電(dian)(dian)(dian)器動(dong)作切斷(duan)(duan)a全回路,使電(dian)(dian)(dian)梯(ti)(ti)停止運(yun)行。這種故障多出在繼電(dian)(dian)(dian)器邏輯控(kong)制(zhi)的電(dian)(dian)(dian)梯(ti)(ti),因(yin)為是(shi)老式(shi)電(dian)(dian)(dian)梯(ti)(ti),電(dian)(dian)(dian)源開關(guan)(guan)多為閘刀(dao)式(shi),電(dian)(dian)(dian)源經過(guo)j限(xian)開關(guan)(guan),再送至電(dian)(dian)(dian)梯(ti)(ti)控(kong)制(zhi)柜(ju)、電(dian)(dian)(dian)源流經的兩個開關(guan)(guan),共六(liu)根(gen)保險(xian)絲(si)。電(dian)(dian)(dian)梯(ti)(ti)運(yun)行、起動(dong),電(dian)(dian)(dian)流都(dou)很大。經過(guo)一(yi)段時間運(yun)行,如維保人(ren)員不(bu)及時檢(jian)查,保險(xian)絲(si)與螺絲(si)連接(jie)處易燒斷(duan)(duan),電(dian)(dian)(dian)梯(ti)(ti)斷(duan)(duan)相(xiang),引起停梯(ti)(ti),輕則關(guan)(guan)人(ren),重則發生事(shi)故。
主要預防措施:
①保養人(ren)員要(yao)經常(chang)巡視(shi)檢查,發(fa)現(xian)可疑之處,及時修理,出現(xian)發(fa)燙、打火花諸類情形應(ying)立即更換。
②建(jian)議用戶將閘刀開關(guan)更換為相當容(rong)量的空氣開關(guan)。
③現在(zai)設(she)計的電(dian)(dian)梯都沒有電(dian)(dian)源j限開關(guan),筆者認(ren)為,可以就(jiu)a全(quan)回(hui)路略作改動(dong),即加(jia)裝上、下j限電(dian)(dian)氣開關(guan)串聯在(zai)a全(quan)回(hui)路中,拆(chai)除原j限開關(guan)。
2、漲繩輪開(kai)關(guan)斷開(kai)引起停梯
像曳引繩(sheng)一樣(yang),限速器繩(sheng)同樣(yang)會(hui)在使用過程中伸長。由于底坑漲繩(sheng)輪重錘的作用,漲繩(sheng)輪開(kai)關(guan)打板偏移,直到斷開(kai)開(kai)關(guan)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)(jian)查一(yi)(yi)次,運行一(yi)(yi)年以后,三個月檢(jian)(jian)查一(yi)(yi)次,如此即可防患于未然。由于廳門(men)密(mi)封不嚴,井道有(you)墻(qiang)洞等各種原因(yin),老鼠竄入井道時有(you)的(de)(de)會摔死,有(you)的(de)(de)掉入底坑因(yin)想(xiang)方(fang)設法(fa)逃(tao)出(chu)竄入繩輪而卡入其中,電梯向下運行導致a全鉗開關(guan)動(dong)作,有(you)的(de)(de)限速器開關(guan)也一(yi)(yi)起聯動(dong)。
