蚌埠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(san)相電(dian)(dian)(dian)(dian)源(yuan)(yuan)出現斷(duan)相時,相序繼(ji)電(dian)(dian)(dian)(dian)器動作切斷(duan)a全回路,使電(dian)(dian)(dian)(dian)梯(ti)(ti)停止運(yun)行(xing)(xing)(xing)。這種(zhong)故障多(duo)(duo)出在繼(ji)電(dian)(dian)(dian)(dian)器邏輯控(kong)制(zhi)的電(dian)(dian)(dian)(dian)梯(ti)(ti),因(yin)為是(shi)老式電(dian)(dian)(dian)(dian)梯(ti)(ti),電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關(guan)(guan)多(duo)(duo)為閘刀(dao)式,電(dian)(dian)(dian)(dian)源(yuan)(yuan)經(jing)過(guo)j限開關(guan)(guan),再送至(zhi)電(dian)(dian)(dian)(dian)梯(ti)(ti)控(kong)制(zhi)柜、電(dian)(dian)(dian)(dian)源(yuan)(yuan)流(liu)(liu)經(jing)的兩個(ge)開關(guan)(guan),共六(liu)根保險絲(si)。電(dian)(dian)(dian)(dian)梯(ti)(ti)運(yun)行(xing)(xing)(xing)、起動,電(dian)(dian)(dian)(dian)流(liu)(liu)都很大。經(jing)過(guo)一(yi)段(duan)時間運(yun)行(xing)(xing)(xing),如維保人(ren)員不及時檢(jian)查(cha),保險絲(si)與螺(luo)絲(si)連接(jie)處易燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)(ti)斷(duan)相,引起停梯(ti)(ti),輕則關(guan)(guan)人(ren),重則發(fa)生事故。
主要預防措施:
①保養人員要經常(chang)巡視檢查,發現可疑之處,及時(shi)修(xiu)理,出現發燙、打(da)火花(hua)諸類(lei)情形(xing)應立即更換(huan)。
②建議用戶(hu)將閘刀開關(guan)更(geng)換(huan)為相當(dang)容量(liang)的空氣開關(guan)。
③現在設計的(de)電梯都沒(mei)有電源j限(xian)開(kai)關(guan),筆者認為,可(ke)以就a全回路(lu)略作改動(dong),即加裝(zhuang)上、下j限(xian)電氣開(kai)關(guan)串聯在a全回路(lu)中,拆除原j限(xian)開(kai)關(guan)。
2、漲繩輪開(kai)關斷(duan)開(kai)引起停梯(ti)
像曳引繩一(yi)樣,限速器繩同樣會在使用過程中(zhong)伸長。由于底(di)坑漲繩輪重(zhong)錘的(de)作用,漲繩輪開關打板偏(pian)移,直到(dao)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(yuan)須每月檢查一(yi)次,運行(xing)一(yi)年以后(hou),三個(ge)月檢查一(yi)次,如(ru)此即可防患于未然(ran)。由于廳門密(mi)封不嚴,井(jing)(jing)道(dao)(dao)有(you)墻洞等各種原因,老(lao)鼠竄入井(jing)(jing)道(dao)(dao)時有(you)的(de)會摔死(si),有(you)的(de)掉入底(di)坑因想方設法逃出竄入繩(sheng)輪(lun)而卡入其中,電梯向(xiang)下運行(xing)導致a全鉗開(kai)關動作,有(you)的(de)限(xian)速器開(kai)關也一(yi)起(qi)聯(lian)動。
