塔吊的液壓該(gai)如何控制?我們(men)一起來看看

隨著(zhu)建(jian)筑(zhu)塔(ta)(ta)吊(diao)(diao)出(chu)租行(xing)業的(de)不(bu)斷(duan)發展，現(xian)在(zai)很多的(de)建(jian)筑(zhu)塔(ta)(ta)吊(diao)(diao)設備的(de)使用技術也隨之增加，塔(ta)(ta)吊(diao)(diao)液壓頂升(sheng)(sheng)系統通過頂升(sheng)(sheng)和下降(jiang)塔(ta)(ta)吊(diao)(diao)套架來實現(xian)增加或(huo)減少標準節，使塔(ta)(ta)吊(diao)(diao)能(neng)隨著(zhu)建(jian)筑(zhu)物高度(du)(du)變化(hua)而(er)升(sheng)(sheng)高或(huo)降(jiang)低，從而(er)滿(man)足不(bu)同高度(du)(du)建(jian)筑(zhu)物的(de)垂(chui)直運輸需(xu)要。

該系統(tong)(tong)(tong)(tong)主要由液(ye)壓(ya)(ya)泵站、液(ye)壓(ya)(ya)頂(ding)(ding)升(sheng)油缸、鎖閥及高壓(ya)(ya)軟管組成；在塔吊(diao)頂(ding)(ding)升(sheng)作(zuo)(zuo)業時，系統(tong)(tong)(tong)(tong)需要承載(zai)塔吊(diao)上部結(jie)構三十多噸的重(zhong)量，系統(tong)(tong)(tong)(tong)工作(zuo)(zuo)壓(ya)(ya)力達到18Mpa以上，屬(shu)于高壓(ya)(ya)液(ye)壓(ya)(ya)系統(tong)(tong)(tong)(tong)。該系統(tong)(tong)(tong)(tong)具(ju)有體積小、重(zhong)量輕、比功率(lv)大、運行平穩等優點，但(dan)同時又存在傳(chuan)動效(xiao)率(lv)低、易產(chan)生(sheng)故障等缺陷。

由于(yu)塔(ta)吊(diao)(diao)的液壓頂升系(xi)統屬于(yu)密(mi)封帶壓的管路(lu)(lu)循(xun)環系(xi)統，管路(lu)(lu)中油液的流動情況，液壓元件(jian)內部的零件(jian)動作和密(mi)封是(shi)否(fou)損壞都(dou)不易察覺到，因(yin)此(ci)分析(xi)故(gu)(gu)障的原因(yin)和判斷故(gu)(gu)障的部位都(dou)比較困難(nan)。有眾多塔(ta)吊(diao)(diao)事故(gu)(gu)中，半數是(shi)因(yin)為(wei)系(xi)統出現故(gu)(gu)障后(hou)處置不當而引發(fa)的，為(wei)避免(mian)重大設備事故(gu)(gu)發(fa)生，如何預防(fang)液壓頂升系(xi)統故(gu)(gu)障就成了一個(ge)急(ji)待解(jie)決(jue)的的問(wen)題(ti)。
