安康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(dang)三相電(dian)(dian)(dian)(dian)(dian)源(yuan)出現斷相時(shi),相序繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)動(dong)作切斷a全回路(lu),使電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)(ti)停(ting)止(zhi)運(yun)行(xing)。這種故障多(duo)出在(zai)繼(ji)電(dian)(dian)(dian)(dian)(dian)器(qi)邏輯控(kong)制的電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)(ti),因為(wei)是老(lao)式電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)(ti),電(dian)(dian)(dian)(dian)(dian)源(yuan)開(kai)關(guan)(guan)多(duo)為(wei)閘(zha)刀式,電(dian)(dian)(dian)(dian)(dian)源(yuan)經(jing)過j限開(kai)關(guan)(guan),再送至(zhi)電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)(ti)控(kong)制柜(ju)、電(dian)(dian)(dian)(dian)(dian)源(yuan)流(liu)經(jing)的兩個開(kai)關(guan)(guan),共六(liu)根保(bao)險(xian)絲。電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)(ti)運(yun)行(xing)、起動(dong),電(dian)(dian)(dian)(dian)(dian)流(liu)都很大。經(jing)過一段(duan)時(shi)間運(yun)行(xing),如維(wei)保(bao)人(ren)員不及時(shi)檢查,保(bao)險(xian)絲與螺(luo)絲連接處易燒斷,電(dian)(dian)(dian)(dian)(dian)梯(ti)(ti)(ti)(ti)(ti)斷相,引起停(ting)梯(ti)(ti)(ti)(ti)(ti),輕則(ze)關(guan)(guan)人(ren),重(zhong)則(ze)發(fa)生事(shi)故。

主要預防措施:

①保養人員要經常巡視檢查,發(fa)現可疑之處,及時修理,出(chu)現發(fa)燙、打火花(hua)諸類情形應立(li)即更換。

②建議(yi)用戶將閘刀開關更換為相當容量的(de)空氣開關。

③現在設計的電(dian)梯都(dou)沒有電(dian)源(yuan)j限(xian)開關,筆者認為(wei),可以(yi)就a全(quan)(quan)回路略作(zuo)改動(dong),即加裝上、下(xia)j限(xian)電(dian)氣開關串聯在a全(quan)(quan)回路中,拆除原j限(xian)開關。

2、漲繩輪開關(guan)斷(duan)開引起停梯

像曳(ye)引繩(sheng)(sheng)一樣,限速器繩(sheng)(sheng)同(tong)樣會在使用(yong)過程中伸長。由于底坑漲繩(sheng)(sheng)輪重錘的作(zuo)用(yong),漲繩(sheng)(sheng)輪開(kai)關打板偏(pian)移,直到斷(duan)開(kai)開(kai)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(mei)月檢(jian)查(cha)一(yi)(yi)次(ci),運行一(yi)(yi)年以(yi)后,三個月檢(jian)查(cha)一(yi)(yi)次(ci),如此(ci)即(ji)可防患于未然。由于廳門密封不嚴,井(jing)道有墻洞(dong)等(deng)各種原因(yin),老鼠竄(cuan)(cuan)入(ru)(ru)井(jing)道時有的(de)會摔死,有的(de)掉(diao)入(ru)(ru)底(di)坑因(yin)想方設法逃(tao)出(chu)竄(cuan)(cuan)入(ru)(ru)繩輪而卡入(ru)(ru)其中,電梯向下(xia)運行導致(zhi)a全(quan)鉗開關動作,有的(de)限速器(qi)開關也一(yi)(yi)起聯動。
