塔(ta)吊的液壓該(gai)如何控制?我們一起來(lai)看(kan)看(kan)
隨著(zhu)(zhu)建(jian)(jian)(jian)筑塔(ta)吊(diao)(diao)出租行業的不(bu)斷發展(zhan),現(xian)在很(hen)多的建(jian)(jian)(jian)筑塔(ta)吊(diao)(diao)設備的使用技術也(ye)隨之增加,塔(ta)吊(diao)(diao)液壓頂(ding)升系統通過頂(ding)升和下降塔(ta)吊(diao)(diao)套架來實(shi)現(xian)增加或減(jian)少標準(zhun)節,使塔(ta)吊(diao)(diao)能隨著(zhu)(zhu)建(jian)(jian)(jian)筑物(wu)高(gao)(gao)度變(bian)化而升高(gao)(gao)或降低(di),從而滿足(zu)不(bu)同(tong)高(gao)(gao)度建(jian)(jian)(jian)筑物(wu)的垂(chui)直運輸(shu)需要(yao)。
該系(xi)統(tong)(tong)主要(yao)由(you)液(ye)壓(ya)(ya)泵(beng)站、液(ye)壓(ya)(ya)頂升油缸、鎖閥及高(gao)壓(ya)(ya)軟管組成;在塔(ta)吊頂升作業時(shi),系(xi)統(tong)(tong)需要(yao)承(cheng)載(zai)塔(ta)吊上部(bu)結構(gou)三十多噸(dun)的重量(liang),系(xi)統(tong)(tong)工作壓(ya)(ya)力達到18Mpa以上,屬(shu)于高(gao)壓(ya)(ya)液(ye)壓(ya)(ya)系(xi)統(tong)(tong)。該系(xi)統(tong)(tong)具有體積小、重量(liang)輕(qing)、比功(gong)率(lv)大、運行平(ping)穩(wen)等(deng)優點,但同時(shi)又(you)存在傳動(dong)效率(lv)低、易產生(sheng)故障等(deng)缺陷。
由于(yu)塔吊(diao)的液(ye)壓頂(ding)升系統屬于(yu)密封(feng)帶(dai)壓的管路循環系統,管路中油液(ye)的流動情況,液(ye)壓元件內(nei)部(bu)的零件動作(zuo)和密封(feng)是否損壞都(dou)不易察覺到,因此分析故(gu)障的原因和判斷(duan)故(gu)障的部(bu)位都(dou)比較困難。有(you)眾多塔吊(diao)事故(gu)中,半數是因為系統出現故(gu)障后處(chu)置(zhi)不當而引發(fa)的,為避免重大設(she)備(bei)事故(gu)發(fa)生,如何預防液(ye)壓頂(ding)升系統故(gu)障就成了一個急(ji)待解決的的問題。
