塔吊的液(ye)壓該如何控(kong)制?我們一起來看(kan)看(kan)
隨(sui)著(zhu)建(jian)筑(zhu)塔(ta)吊(diao)(diao)出(chu)租行業的不(bu)斷發展,現在很多的建(jian)筑(zhu)塔(ta)吊(diao)(diao)設備的使(shi)用技術也隨(sui)之增加,塔(ta)吊(diao)(diao)液壓頂升系統通過頂升和下降塔(ta)吊(diao)(diao)套架來(lai)實現增加或(huo)減(jian)少標準節(jie),使(shi)塔(ta)吊(diao)(diao)能隨(sui)著(zhu)建(jian)筑(zhu)物高度變(bian)化而(er)升高或(huo)降低(di),從而(er)滿足不(bu)同高度建(jian)筑(zhu)物的垂直運輸需要。
該系(xi)(xi)統(tong)主要由(you)液壓(ya)(ya)泵站、液壓(ya)(ya)頂(ding)升油缸(gang)、鎖(suo)閥及(ji)高(gao)壓(ya)(ya)軟管(guan)組(zu)成;在塔吊頂(ding)升作(zuo)業時,系(xi)(xi)統(tong)需要承載塔吊上部結構三十多噸的(de)重量,系(xi)(xi)統(tong)工作(zuo)壓(ya)(ya)力達到(dao)18Mpa以上,屬于高(gao)壓(ya)(ya)液壓(ya)(ya)系(xi)(xi)統(tong)。該系(xi)(xi)統(tong)具有體積小(xiao)、重量輕、比功率(lv)大、運行(xing)平穩(wen)等優點,但(dan)同時又(you)存在傳動效率(lv)低、易產生故障等缺陷。
由(you)于塔吊的液(ye)(ye)壓頂升(sheng)(sheng)系(xi)統(tong)(tong)屬于密封帶(dai)壓的管路循環(huan)系(xi)統(tong)(tong),管路中(zhong)油液(ye)(ye)的流動(dong)情況,液(ye)(ye)壓元件內部的零件動(dong)作和(he)密封是否損壞都(dou)不(bu)(bu)易察覺到(dao),因此分析故(gu)障(zhang)的原因和(he)判斷故(gu)障(zhang)的部位都(dou)比較(jiao)困難(nan)。有眾多(duo)塔吊事故(gu)中(zhong),半數是因為(wei)系(xi)統(tong)(tong)出(chu)現故(gu)障(zhang)后處(chu)置不(bu)(bu)當(dang)而引發的,為(wei)避免重大設備事故(gu)發生,如(ru)何預防液(ye)(ye)壓頂升(sheng)(sheng)系(xi)統(tong)(tong)故(gu)障(zhang)就成了一個急(ji)待(dai)解(jie)決的的問(wen)題(ti)。
