塔吊的液(ye)壓該(gai)如何控制(zhi)?我們一起來看看
隨(sui)(sui)著建(jian)(jian)筑(zhu)塔(ta)吊出(chu)租行(xing)業(ye)的不斷發展,現(xian)在很多的建(jian)(jian)筑(zhu)塔(ta)吊設備(bei)的使(shi)(shi)用技術也隨(sui)(sui)之(zhi)增(zeng)加,塔(ta)吊液壓頂(ding)升系統通(tong)過頂(ding)升和下降塔(ta)吊套(tao)架來實現(xian)增(zeng)加或減少標準節(jie),使(shi)(shi)塔(ta)吊能隨(sui)(sui)著建(jian)(jian)筑(zhu)物高(gao)(gao)度變化而(er)升高(gao)(gao)或降低,從而(er)滿足(zu)不同高(gao)(gao)度建(jian)(jian)筑(zhu)物的垂直運(yun)輸需要。
該系(xi)統(tong)(tong)(tong)主要由液壓(ya)泵站、液壓(ya)頂(ding)升油缸、鎖閥(fa)及高壓(ya)軟(ruan)管組(zu)成;在塔吊頂(ding)升作業時,系(xi)統(tong)(tong)(tong)需要承載塔吊上部(bu)結構(gou)三十多噸(dun)的重(zhong)量(liang),系(xi)統(tong)(tong)(tong)工作壓(ya)力(li)達(da)到18Mpa以上,屬于高壓(ya)液壓(ya)系(xi)統(tong)(tong)(tong)。該系(xi)統(tong)(tong)(tong)具有體積小、重(zhong)量(liang)輕、比功率(lv)大、運行(xing)平穩等(deng)優點,但同時又(you)存在傳動(dong)效率(lv)低、易產(chan)生(sheng)故障等(deng)缺陷。
由于塔(ta)吊(diao)的(de)(de)(de)(de)液壓頂升(sheng)系(xi)統(tong)(tong)屬(shu)于密封帶壓的(de)(de)(de)(de)管路循(xun)環系(xi)統(tong)(tong),管路中(zhong)油(you)液的(de)(de)(de)(de)流動情況(kuang),液壓元件內部的(de)(de)(de)(de)零件動作和密封是否損壞都不易察覺到,因此分(fen)析故(gu)障(zhang)(zhang)的(de)(de)(de)(de)原因和判斷故(gu)障(zhang)(zhang)的(de)(de)(de)(de)部位都比(bi)較困難(nan)。有眾多塔(ta)吊(diao)事故(gu)中(zhong),半數(shu)是因為(wei)系(xi)統(tong)(tong)出現故(gu)障(zhang)(zhang)后處置(zhi)不當而引發的(de)(de)(de)(de),為(wei)避免重(zhong)大設備事故(gu)發生,如(ru)何預防液壓頂升(sheng)系(xi)統(tong)(tong)故(gu)障(zhang)(zhang)就成了一(yi)個急(ji)待解決的(de)(de)(de)(de)的(de)(de)(de)(de)問題。
