塔吊的液壓該如何控制?我們一起(qi)來(lai)看(kan)看(kan)
隨(sui)(sui)著(zhu)(zhu)建(jian)(jian)筑(zhu)(zhu)塔吊(diao)(diao)出(chu)租行(xing)業的(de)不(bu)斷發展,現(xian)在很多的(de)建(jian)(jian)筑(zhu)(zhu)塔吊(diao)(diao)設備的(de)使用(yong)技術也(ye)隨(sui)(sui)之增加(jia),塔吊(diao)(diao)液壓頂升(sheng)系統通過頂升(sheng)和下降(jiang)塔吊(diao)(diao)套(tao)架(jia)來(lai)實現(xian)增加(jia)或減少標準(zhun)節,使塔吊(diao)(diao)能隨(sui)(sui)著(zhu)(zhu)建(jian)(jian)筑(zhu)(zhu)物(wu)(wu)高度(du)變化而升(sheng)高或降(jiang)低,從而滿(man)足不(bu)同高度(du)建(jian)(jian)筑(zhu)(zhu)物(wu)(wu)的(de)垂直(zhi)運輸需要。
該(gai)系(xi)統(tong)(tong)主要由(you)液壓(ya)(ya)泵站、液壓(ya)(ya)頂升(sheng)(sheng)油缸(gang)、鎖閥(fa)及高壓(ya)(ya)軟管組成(cheng);在塔(ta)吊頂升(sheng)(sheng)作(zuo)業時,系(xi)統(tong)(tong)需要承載塔(ta)吊上部(bu)結構三十(shi)多(duo)噸的重量,系(xi)統(tong)(tong)工作(zuo)壓(ya)(ya)力達(da)到18Mpa以上,屬(shu)于高壓(ya)(ya)液壓(ya)(ya)系(xi)統(tong)(tong)。該(gai)系(xi)統(tong)(tong)具有體積小(xiao)、重量輕、比功率大、運行平穩等(deng)優點,但(dan)同(tong)時又存在傳動效率低、易產生(sheng)故障等(deng)缺陷。
由于塔(ta)吊的(de)(de)液壓(ya)頂(ding)升系(xi)(xi)統(tong)(tong)屬(shu)于密(mi)封(feng)帶壓(ya)的(de)(de)管路(lu)循環系(xi)(xi)統(tong)(tong),管路(lu)中油(you)液的(de)(de)流動(dong)情況,液壓(ya)元(yuan)件(jian)內部的(de)(de)零件(jian)動(dong)作(zuo)和密(mi)封(feng)是否損(sun)壞都不(bu)易察覺到(dao),因(yin)此分析故(gu)(gu)(gu)(gu)障的(de)(de)原因(yin)和判斷故(gu)(gu)(gu)(gu)障的(de)(de)部位都比較困難。有眾多塔(ta)吊事故(gu)(gu)(gu)(gu)中,半數是因(yin)為(wei)系(xi)(xi)統(tong)(tong)出現(xian)故(gu)(gu)(gu)(gu)障后處(chu)置(zhi)不(bu)當(dang)而引發(fa)的(de)(de),為(wei)避免(mian)重大設備事故(gu)(gu)(gu)(gu)發(fa)生(sheng),如何預防液壓(ya)頂(ding)升系(xi)(xi)統(tong)(tong)故(gu)(gu)(gu)(gu)障就成了(le)一個急(ji)待解決的(de)(de)的(de)(de)問(wen)題。
