平涼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(xiang)電(dian)(dian)(dian)源出現斷(duan)相(xiang)時(shi)(shi),相(xiang)序繼(ji)(ji)電(dian)(dian)(dian)器動(dong)作切斷(duan)a全回路(lu),使(shi)電(dian)(dian)(dian)梯(ti)(ti)(ti)停(ting)止運(yun)行。這種故障多出在繼(ji)(ji)電(dian)(dian)(dian)器邏輯(ji)控制的電(dian)(dian)(dian)梯(ti)(ti)(ti),因為(wei)是老(lao)式電(dian)(dian)(dian)梯(ti)(ti)(ti),電(dian)(dian)(dian)源開關(guan)(guan)(guan)多為(wei)閘刀(dao)式,電(dian)(dian)(dian)源經過(guo)j限開關(guan)(guan)(guan),再送至電(dian)(dian)(dian)梯(ti)(ti)(ti)控制柜、電(dian)(dian)(dian)源流經的兩個開關(guan)(guan)(guan),共六根保險絲(si)。電(dian)(dian)(dian)梯(ti)(ti)(ti)運(yun)行、起(qi)動(dong),電(dian)(dian)(dian)流都很(hen)大。經過(guo)一(yi)段時(shi)(shi)間運(yun)行,如維保人員不及時(shi)(shi)檢查,保險絲(si)與螺(luo)絲(si)連(lian)接處易燒(shao)斷(duan),電(dian)(dian)(dian)梯(ti)(ti)(ti)斷(duan)相(xiang),引起(qi)停(ting)梯(ti)(ti)(ti),輕則關(guan)(guan)(guan)人,重則發(fa)生事(shi)故。
主要預防措施:
①保(bao)養人員要經常(chang)巡視(shi)檢查,發(fa)現可疑之處,及時修理,出現發(fa)燙、打火花諸類(lei)情形應立即(ji)更換。
②建(jian)議用戶(hu)將(jiang)閘刀開(kai)關更換為(wei)相當容量的空氣(qi)開(kai)關。
③現在(zai)設(she)計(ji)的電(dian)梯都(dou)沒(mei)有電(dian)源j限(xian)開關(guan)(guan),筆(bi)者認為,可以(yi)就a全(quan)回路(lu)略(lve)作改動,即加裝上、下j限(xian)電(dian)氣開關(guan)(guan)串聯在(zai)a全(quan)回路(lu)中,拆除原(yuan)j限(xian)開關(guan)(guan)。
2、漲(zhang)繩輪(lun)開關(guan)斷開引起停梯
像(xiang)曳(ye)引繩(sheng)一樣,限速器繩(sheng)同樣會(hui)在使用過程中伸長。由于底(di)坑漲繩(sheng)輪重錘的作用,漲繩(sheng)輪開關打(da)板偏移,直到斷(duan)開開關導致(zhi)停梯(ti)。
對于電梯安裝的新裝電梯,電梯安裝人員須每月(yue)(yue)檢查一(yi)(yi)次,運行(xing)(xing)一(yi)(yi)年以后,三個月(yue)(yue)檢查一(yi)(yi)次,如此(ci)即可防患(huan)于未(wei)然。由于廳(ting)門(men)密封不嚴,井道(dao)有墻洞等各種原因(yin),老鼠竄(cuan)入(ru)(ru)井道(dao)時有的會摔(shuai)死(si),有的掉入(ru)(ru)底坑(keng)因(yin)想方設(she)法(fa)逃出(chu)竄(cuan)入(ru)(ru)繩輪(lun)而卡入(ru)(ru)其中,電梯向下運行(xing)(xing)導致a全鉗開關動作,有的限速器(qi)開關也一(yi)(yi)起聯動。
