塔吊的(de)液(ye)壓該(gai)如何控制?我們一(yi)起來看看

隨著(zhu)建(jian)(jian)筑(zhu)塔(ta)(ta)吊(diao)(diao)出(chu)租行業的不斷發展，現在很多的建(jian)(jian)筑(zhu)塔(ta)(ta)吊(diao)(diao)設備的使用(yong)技術也隨之增(zeng)加，塔(ta)(ta)吊(diao)(diao)液(ye)壓頂升(sheng)(sheng)系統通過頂升(sheng)(sheng)和下(xia)降(jiang)塔(ta)(ta)吊(diao)(diao)套架(jia)來(lai)實現增(zeng)加或(huo)(huo)減(jian)少標準節，使塔(ta)(ta)吊(diao)(diao)能隨著(zhu)建(jian)(jian)筑(zhu)物高度變化而升(sheng)(sheng)高或(huo)(huo)降(jiang)低，從(cong)而滿足不同高度建(jian)(jian)筑(zhu)物的垂(chui)直運(yun)輸(shu)需(xu)要。

該系(xi)統(tong)(tong)(tong)(tong)主要由液壓(ya)(ya)(ya)泵站(zhan)、液壓(ya)(ya)(ya)頂升(sheng)油缸(gang)、鎖閥及高壓(ya)(ya)(ya)軟管(guan)組成(cheng)；在塔吊頂升(sheng)作業時(shi)，系(xi)統(tong)(tong)(tong)(tong)需要承載塔吊上部結(jie)構(gou)三十多噸(dun)的(de)重(zhong)量，系(xi)統(tong)(tong)(tong)(tong)工作壓(ya)(ya)(ya)力達(da)到(dao)18Mpa以上，屬于高壓(ya)(ya)(ya)液壓(ya)(ya)(ya)系(xi)統(tong)(tong)(tong)(tong)。該系(xi)統(tong)(tong)(tong)(tong)具有體積小、重(zhong)量輕、比功率大、運行平穩等(deng)優點，但同時(shi)又存在傳動(dong)效率低(di)、易(yi)產生故(gu)障等(deng)缺陷。

由于塔吊的液壓頂(ding)(ding)升系(xi)(xi)統(tong)(tong)屬于密封帶壓的管路循環系(xi)(xi)統(tong)(tong)，管路中(zhong)油液的流動(dong)情(qing)況，液壓元件(jian)內部(bu)的零件(jian)動(dong)作和密封是(shi)否損壞都不(bu)易察覺到，因(yin)(yin)此分析故(gu)障的原因(yin)(yin)和判斷故(gu)障的部(bu)位都比較困難。有眾多(duo)塔吊事故(gu)中(zhong)，半數是(shi)因(yin)(yin)為(wei)系(xi)(xi)統(tong)(tong)出現故(gu)障后處置(zhi)不(bu)當而引發的，為(wei)避免重(zhong)大設備(bei)事故(gu)發生，如何(he)預防液壓頂(ding)(ding)升系(xi)(xi)統(tong)(tong)故(gu)障就(jiu)成了一(yi)個急待解決的的問題。
