長沙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
當三相電(dian)(dian)(dian)(dian)源出(chu)現(xian)斷(duan)(duan)相時(shi),相序繼(ji)電(dian)(dian)(dian)(dian)器動(dong)(dong)作切(qie)斷(duan)(duan)a全回路,使電(dian)(dian)(dian)(dian)梯停(ting)止運(yun)行。這種故障多出(chu)在(zai)繼(ji)電(dian)(dian)(dian)(dian)器邏輯控(kong)(kong)制(zhi)的電(dian)(dian)(dian)(dian)梯,因為(wei)是老式電(dian)(dian)(dian)(dian)梯,電(dian)(dian)(dian)(dian)源開關(guan)多為(wei)閘刀式,電(dian)(dian)(dian)(dian)源經(jing)(jing)過(guo)(guo)j限開關(guan),再送至(zhi)電(dian)(dian)(dian)(dian)梯控(kong)(kong)制(zhi)柜、電(dian)(dian)(dian)(dian)源流經(jing)(jing)的兩(liang)個開關(guan),共六根保(bao)險(xian)絲。電(dian)(dian)(dian)(dian)梯運(yun)行、起動(dong)(dong),電(dian)(dian)(dian)(dian)流都很大(da)。經(jing)(jing)過(guo)(guo)一段時(shi)間(jian)運(yun)行,如(ru)維保(bao)人員不及時(shi)檢查,保(bao)險(xian)絲與螺絲連(lian)接處易(yi)燒斷(duan)(duan),電(dian)(dian)(dian)(dian)梯斷(duan)(duan)相,引起停(ting)梯,輕(qing)則(ze)關(guan)人,重則(ze)發(fa)生事故。
主要預防措施:
①保(bao)養人(ren)員要(yao)經(jing)常(chang)巡視(shi)檢查(cha),發現可疑之處,及時修理,出現發燙(tang)、打火花諸類情形應立即更(geng)換。
②建議用戶將閘刀開關(guan)更(geng)換為相當容量的空氣開關(guan)。
③現在(zai)設計的電梯都沒有電源j限開關,筆者(zhe)認為(wei),可以就a全回路(lu)略作改動,即加裝上、下(xia)j限電氣開關串(chuan)聯在(zai)a全回路(lu)中,拆(chai)除原(yuan)j限開關。
2、漲繩輪開(kai)關斷(duan)開(kai)引(yin)起停(ting)梯
像曳引繩(sheng)一樣,限速器繩(sheng)同樣會在使(shi)用過(guo)程中伸長。由于底坑漲(zhang)繩(sheng)輪(lun)重錘的作用,漲(zhang)繩(sheng)輪(lun)開關打板偏移,直到斷開開關導致停梯。
對于電梯安裝的新裝電梯,電梯安裝人員須每月檢查一(yi)次,運行一(yi)年(nian)以后,三個(ge)月檢查一(yi)次,如此即可(ke)防患于未然。由于廳門密封不嚴,井道有墻(qiang)洞等(deng)各種原因,老鼠(shu)竄(cuan)入井道時有的(de)會摔死,有的(de)掉入底坑(keng)因想方設法(fa)逃出竄(cuan)入繩輪而卡入其中(zhong),電梯向下(xia)運行導致a全鉗開關(guan)(guan)動(dong)作,有的(de)限速器開關(guan)(guan)也一(yi)起聯動(dong)。
