塔(ta)吊(diao)的液壓該如何(he)控制?我們一起來(lai)看(kan)看(kan)

隨(sui)著建筑(zhu)(zhu)(zhu)塔吊出租行(xing)業的(de)(de)不斷發(fa)展，現(xian)在很多的(de)(de)建筑(zhu)(zhu)(zhu)塔吊設(she)備的(de)(de)使用技術(shu)也隨(sui)之(zhi)增(zeng)加，塔吊液壓頂升(sheng)系統通過頂升(sheng)和下降(jiang)塔吊套架來實現(xian)增(zeng)加或減(jian)少標準節，使塔吊能隨(sui)著建筑(zhu)(zhu)(zhu)物高度變化而升(sheng)高或降(jiang)低，從(cong)而滿足(zu)不同(tong)高度建筑(zhu)(zhu)(zhu)物的(de)(de)垂直運輸需要。

該系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)主要(yao)由液壓(ya)(ya)(ya)泵站、液壓(ya)(ya)(ya)頂(ding)升油缸、鎖閥及高(gao)壓(ya)(ya)(ya)軟(ruan)管組成；在塔吊(diao)頂(ding)升作業(ye)時(shi)，系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)需要(yao)承載塔吊(diao)上部結構(gou)三十多噸的重(zhong)量(liang)，系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)工(gong)作壓(ya)(ya)(ya)力達到18Mpa以上，屬于高(gao)壓(ya)(ya)(ya)液壓(ya)(ya)(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)。該系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)具有體積小(xiao)、重(zhong)量(liang)輕、比(bi)功率大、運行(xing)平穩等優點，但同時(shi)又存在傳動效(xiao)率低、易產生故障(zhang)等缺陷。

由于塔吊的(de)(de)(de)(de)液(ye)壓(ya)(ya)頂升(sheng)系(xi)統屬于密封(feng)帶壓(ya)(ya)的(de)(de)(de)(de)管路(lu)循環系(xi)統，管路(lu)中油液(ye)的(de)(de)(de)(de)流動情況，液(ye)壓(ya)(ya)元(yuan)件(jian)(jian)內(nei)部(bu)的(de)(de)(de)(de)零(ling)件(jian)(jian)動作和(he)密封(feng)是(shi)否損壞(huai)都不易察覺(jue)到，因(yin)此分析故(gu)障(zhang)(zhang)的(de)(de)(de)(de)原(yuan)因(yin)和(he)判斷故(gu)障(zhang)(zhang)的(de)(de)(de)(de)部(bu)位都比較困難。有眾多塔吊事故(gu)中，半數(shu)是(shi)因(yin)為系(xi)統出現故(gu)障(zhang)(zhang)后處置(zhi)不當(dang)而(er)引發(fa)的(de)(de)(de)(de)，為避免(mian)重大設備事故(gu)發(fa)生，如何(he)預防液(ye)壓(ya)(ya)頂升(sheng)系(xi)統故(gu)障(zhang)(zhang)就成了一個急(ji)待解(jie)決的(de)(de)(de)(de)的(de)(de)(de)(de)問(wen)題。
