安徽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)源出現斷(duan)相(xiang)時(shi),相(xiang)序繼電(dian)(dian)(dian)(dian)器動作切斷(duan)a全回路,使電(dian)(dian)(dian)(dian)梯(ti)(ti)停(ting)止運(yun)行。這種故(gu)障多出在(zai)繼電(dian)(dian)(dian)(dian)器邏輯控制(zhi)的(de)電(dian)(dian)(dian)(dian)梯(ti)(ti),因為是(shi)老式(shi)電(dian)(dian)(dian)(dian)梯(ti)(ti),電(dian)(dian)(dian)(dian)源開(kai)關(guan)多為閘(zha)刀式(shi),電(dian)(dian)(dian)(dian)源經(jing)(jing)過(guo)j限開(kai)關(guan),再送(song)至電(dian)(dian)(dian)(dian)梯(ti)(ti)控制(zhi)柜、電(dian)(dian)(dian)(dian)源流經(jing)(jing)的(de)兩個開(kai)關(guan),共六根保險絲。電(dian)(dian)(dian)(dian)梯(ti)(ti)運(yun)行、起動,電(dian)(dian)(dian)(dian)流都很大。經(jing)(jing)過(guo)一段時(shi)間運(yun)行,如(ru)維保人(ren)員(yuan)不及(ji)時(shi)檢查(cha),保險絲與螺絲連接處易(yi)燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)(ti)斷(duan)相(xiang),引起停(ting)梯(ti)(ti),輕(qing)則關(guan)人(ren),重則發生事故(gu)。
主要預防措施:
①保養人員要經常(chang)巡視檢查,發現可(ke)疑(yi)之處,及時修理,出現發燙、打火花諸(zhu)類情(qing)形應(ying)立即更換。
②建議用戶將閘刀開關更換為相當(dang)容量的空氣開關。
③現在(zai)設計的電梯都沒(mei)有(you)電源j限(xian)(xian)開關(guan),筆者認為,可以就a全回(hui)路(lu)略作改動(dong),即加裝上、下j限(xian)(xian)電氣開關(guan)串聯(lian)在(zai)a全回(hui)路(lu)中,拆除原j限(xian)(xian)開關(guan)。
2、漲繩輪開關斷開引起停梯
像(xiang)曳(ye)引(yin)繩一樣,限速器繩同(tong)樣會在使用過程(cheng)中伸長。由于(yu)底坑漲(zhang)繩輪重錘的作用,漲(zhang)繩輪開(kai)(kai)(kai)關打板偏移,直(zhi)到斷開(kai)(kai)(kai)開(kai)(kai)(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(xu)每月檢查一(yi)次(ci),運行一(yi)年以后,三個月檢查一(yi)次(ci),如此(ci)即可防患(huan)于(yu)未然。由(you)于(yu)廳門密封(feng)不嚴,井(jing)道有(you)墻洞(dong)等各種原因(yin),老(lao)鼠(shu)竄入井(jing)道時有(you)的(de)(de)會(hui)摔死,有(you)的(de)(de)掉(diao)入底坑因(yin)想方設法逃出竄入繩輪而(er)卡入其(qi)中(zhong),電梯向下運行導致(zhi)a全鉗(qian)開關動(dong)作,有(you)的(de)(de)限速器開關也一(yi)起(qi)聯(lian)動(dong)。
