杭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
當三(san)相(xiang)電(dian)(dian)(dian)源(yuan)(yuan)出現斷相(xiang)時(shi),相(xiang)序繼(ji)電(dian)(dian)(dian)器動作切(qie)斷a全回路(lu),使(shi)電(dian)(dian)(dian)梯(ti)(ti)(ti)停止運(yun)行(xing)(xing)。這種故障(zhang)多(duo)出在繼(ji)電(dian)(dian)(dian)器邏輯(ji)控制(zhi)(zhi)的電(dian)(dian)(dian)梯(ti)(ti)(ti),因(yin)為是老式(shi)(shi)電(dian)(dian)(dian)梯(ti)(ti)(ti),電(dian)(dian)(dian)源(yuan)(yuan)開(kai)關(guan)(guan)(guan)(guan)多(duo)為閘刀式(shi)(shi),電(dian)(dian)(dian)源(yuan)(yuan)經過(guo)j限開(kai)關(guan)(guan)(guan)(guan),再送至(zhi)電(dian)(dian)(dian)梯(ti)(ti)(ti)控制(zhi)(zhi)柜(ju)、電(dian)(dian)(dian)源(yuan)(yuan)流(liu)經的兩個(ge)開(kai)關(guan)(guan)(guan)(guan),共六根保(bao)險(xian)絲。電(dian)(dian)(dian)梯(ti)(ti)(ti)運(yun)行(xing)(xing)、起動,電(dian)(dian)(dian)流(liu)都(dou)很大。經過(guo)一段時(shi)間(jian)運(yun)行(xing)(xing),如(ru)維保(bao)人員不及時(shi)檢查(cha),保(bao)險(xian)絲與螺絲連(lian)接處易燒斷,電(dian)(dian)(dian)梯(ti)(ti)(ti)斷相(xiang),引(yin)起停梯(ti)(ti)(ti),輕則(ze)關(guan)(guan)(guan)(guan)人,重則(ze)發生事故。
主要預防措施:
①保養人(ren)員(yuan)要經(jing)常巡視檢查,發現可疑之(zhi)處,及時修(xiu)理,出現發燙、打火(huo)花(hua)諸類情(qing)形應立(li)即更換。
②建議用戶將閘刀(dao)開關更(geng)換為(wei)相當(dang)容量的空氣開關。
③現在設計的電梯都沒有電源j限(xian)開關(guan),筆者認(ren)為,可(ke)以(yi)就a全回路略(lve)作改動,即加裝(zhuang)上、下j限(xian)電氣開關(guan)串聯(lian)在a全回路中(zhong),拆除原j限(xian)開關(guan)。
2、漲(zhang)繩輪開關斷開引(yin)起停梯
像曳引繩(sheng)一樣,限速器繩(sheng)同樣會在使用過程中伸長。由于底坑(keng)漲(zhang)繩(sheng)輪(lun)重錘(chui)的作(zuo)用,漲(zhang)繩(sheng)輪(lun)開關(guan)打板偏移,直到斷開開關(guan)導致停(ting)梯。
對于電梯安裝的新裝電梯,電梯安裝人員須每月檢查一次,運行(xing)一年(nian)以后,三(san)個月檢查一次,如此即可防(fang)患于(yu)未然(ran)。由于(yu)廳門密封不嚴,井(jing)道有墻洞等(deng)各(ge)種原因(yin),老鼠(shu)竄入井(jing)道時(shi)有的(de)會(hui)摔死,有的(de)掉(diao)入底坑(keng)因(yin)想方設(she)法逃出(chu)竄入繩(sheng)輪而(er)卡入其中,電梯向下(xia)運行(xing)導致a全鉗(qian)開(kai)關動(dong)作(zuo),有的(de)限速器開(kai)關也(ye)一起聯動(dong)。
