賀州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(san)相(xiang)電(dian)(dian)(dian)(dian)源(yuan)(yuan)出現斷(duan)相(xiang)時(shi),相(xiang)序繼(ji)電(dian)(dian)(dian)(dian)器(qi)動作切斷(duan)a全(quan)回路(lu),使電(dian)(dian)(dian)(dian)梯(ti)停止運(yun)行。這種故障(zhang)多出在繼(ji)電(dian)(dian)(dian)(dian)器(qi)邏輯控(kong)制的電(dian)(dian)(dian)(dian)梯(ti),因(yin)為是(shi)老(lao)式電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關多為閘刀式,電(dian)(dian)(dian)(dian)源(yuan)(yuan)經過j限(xian)開關,再(zai)送至(zhi)電(dian)(dian)(dian)(dian)梯(ti)控(kong)制柜(ju)、電(dian)(dian)(dian)(dian)源(yuan)(yuan)流(liu)經的兩個開關,共六根保險絲。電(dian)(dian)(dian)(dian)梯(ti)運(yun)行、起動,電(dian)(dian)(dian)(dian)流(liu)都很大。經過一段時(shi)間運(yun)行,如維保人員(yuan)不及時(shi)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),引起停梯(ti),輕則關人,重則發生事故。
主要預防措施:
①保(bao)養人(ren)員要經常巡(xun)視檢查,發(fa)現可疑(yi)之處,及(ji)時(shi)修(xiu)理,出現發(fa)燙、打火花諸類(lei)情形應立即更換。
②建議用戶(hu)將(jiang)閘刀開(kai)關(guan)(guan)更換(huan)為相當容量的(de)空(kong)氣開(kai)關(guan)(guan)。
③現在設計的電(dian)梯都沒有電(dian)源j限(xian)開關,筆者認為,可以就a全(quan)回(hui)路略(lve)作改動,即加裝上、下j限(xian)電(dian)氣開關串聯(lian)在a全(quan)回(hui)路中,拆除原j限(xian)開關。
2、漲繩輪(lun)開關斷開引起停梯
像曳引繩一樣(yang),限速器繩同樣(yang)會(hui)在使(shi)用(yong)過程中伸長。由于底坑漲繩輪(lun)重錘的作用(yong),漲繩輪(lun)開關打板(ban)偏(pian)移(yi),直(zhi)到(dao)斷開開關導致(zhi)停梯(ti)。
對于電梯安裝的新裝電梯,電梯安裝人員須(xu)每月檢(jian)查(cha)一(yi)(yi)次(ci),運行(xing)一(yi)(yi)年以后(hou),三個月檢(jian)查(cha)一(yi)(yi)次(ci),如此(ci)即可防患于(yu)未然。由(you)于(yu)廳(ting)門密(mi)封不嚴,井道(dao)有(you)墻洞等各種原因(yin),老鼠竄(cuan)入井道(dao)時(shi)有(you)的會摔(shuai)死,有(you)的掉(diao)入底坑因(yin)想方設法逃出(chu)竄(cuan)入繩(sheng)輪而卡(ka)入其中,電梯向下運行(xing)導致(zhi)a全鉗開關(guan)動作,有(you)的限速器(qi)開關(guan)也一(yi)(yi)起聯(lian)動。
