咸陽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)三相電(dian)(dian)(dian)(dian)源(yuan)出(chu)現斷(duan)相時,相序繼(ji)電(dian)(dian)(dian)(dian)器(qi)動作(zuo)切斷(duan)a全回路(lu),使電(dian)(dian)(dian)(dian)梯(ti)停(ting)(ting)止運行。這(zhe)種故障多出(chu)在繼(ji)電(dian)(dian)(dian)(dian)器(qi)邏輯控(kong)制(zhi)的電(dian)(dian)(dian)(dian)梯(ti),因為是老式電(dian)(dian)(dian)(dian)梯(ti),電(dian)(dian)(dian)(dian)源(yuan)開關(guan)多為閘(zha)刀式,電(dian)(dian)(dian)(dian)源(yuan)經(jing)過(guo)j限開關(guan),再送至電(dian)(dian)(dian)(dian)梯(ti)控(kong)制(zhi)柜、電(dian)(dian)(dian)(dian)源(yuan)流經(jing)的兩個開關(guan),共(gong)六根保險(xian)絲(si)。電(dian)(dian)(dian)(dian)梯(ti)運行、起(qi)動,電(dian)(dian)(dian)(dian)流都很大。經(jing)過(guo)一(yi)段時間運行,如維保人(ren)員不及(ji)時檢查,保險(xian)絲(si)與螺絲(si)連(lian)接處易燒斷(duan),電(dian)(dian)(dian)(dian)梯(ti)斷(duan)相,引起(qi)停(ting)(ting)梯(ti),輕則關(guan)人(ren),重則發生(sheng)事(shi)故。
主要預防措施:
①保養(yang)人(ren)員要經常巡視檢(jian)查,發(fa)現(xian)可疑之(zhi)處(chu),及時修理,出(chu)現(xian)發(fa)燙、打火花諸類情(qing)形(xing)應(ying)立即更換。
②建議用戶將(jiang)閘刀開關更換(huan)為相當容(rong)量(liang)的(de)空氣開關。
③現在設計的電(dian)梯都沒有電(dian)源j限(xian)開關(guan)(guan),筆者認為,可(ke)以就(jiu)a全回(hui)路(lu)略作(zuo)改動,即加裝上、下j限(xian)電(dian)氣(qi)開關(guan)(guan)串聯在a全回(hui)路(lu)中(zhong),拆除原j限(xian)開關(guan)(guan)。
2、漲繩輪開關斷開引(yin)起停梯
像(xiang)曳(ye)引繩一(yi)樣(yang),限速器繩同樣(yang)會在使用過程中(zhong)伸長(chang)。由于底(di)坑(keng)漲(zhang)繩輪重錘的作用,漲(zhang)繩輪開關打(da)板偏(pian)移(yi),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(yuan)須每月(yue)檢查一(yi)次,運行一(yi)年(nian)以后,三個(ge)月(yue)檢查一(yi)次,如(ru)此即可防患于未(wei)然。由于廳門密(mi)封不嚴,井道有(you)墻洞等各種原(yuan)因(yin),老鼠竄(cuan)入井道時(shi)有(you)的會摔死,有(you)的掉入底坑因(yin)想方設法逃出竄(cuan)入繩輪而卡入其中(zhong),電梯向下運行導(dao)致(zhi)a全鉗(qian)開關動(dong)作,有(you)的限速(su)器開關也一(yi)起聯動(dong)。
