今天又是新的一周開始,特力小編為你介紹一下四柱液壓機常常會運用的(de)幾種不同油管。
液壓(ya)機的(de)體(ti)系中(zhong)運用的(de)油管,有鋼(gang)管、銅管、尼龍管、橡膠軟管和(he)塑料(liao)管等多(duo)種,它們應根據銜接(jie)元件的(de)相對(dui)方(fang)位、運用環境和(he)工作壓(ya)力來進(jin)行(xing)挑選。
銅管(guan)(guan)(guan)、鋼(gang)(gang)管(guan)(guan)(guan)和尼龍管(guan)(guan)(guan)歸于硬(ying)管(guan)(guan)(guan),用(yong)(yong)于銜(xian)接相對方(fang)位不(bu)變(bian)的固定(ding)元件。鋼(gang)(gang)管(guan)(guan)(guan)能承(cheng)受高壓(ya),價格便(bian)宜(yi),耐油、抗腐蝕和剛性都(dou)較好。但安(an)裝中不(bu)能任意曲折,常(chang)用(yong)(yong)于安(an)裝方(fang)便(bian)的壓(ya)力管(guan)(guan)(guan)道(dao)處。紫(zi)鋼(gang)(gang)管(guan)(guan)(guan)曲折比(bi)較方(fang)便(bian),因為(wei)剛度(du)小(xiao)在安(an)裝時還可有(you)小(xiao)量變(bian)形,故便(bian)于安(an)裝。
但(dan)承壓才能(neng)(neng)低(一(yi)般(ban)不超(chao)過65X10,~10X10Pa),價格也貴,抗展才能(neng)(neng)弱又易使(shi)油(you)(you)液氧化,應盡(jin)量少用(yong)。黃銅(tong)管承壓才能(neng)(neng)較高(達250X10Pa),但(dan)曲折較難。尼龍管的耐壓才能(neng)(neng)可達25X10~80X10Pa。在油(you)(you)中(zhong)加熱到160一(yi)1700就能(neng)(neng)隨意曲折,實際生產中(zhong)多用(yong)來作(zuo)回油(you)(you)管。
橡膠(jiao)管(guan)(guan)、塑料軟管(guan)(guan)常用(yong)于(yu)兩(liang)個相對運動元件之間的銜接。橡膠(jiao)管(guan)(guan)分高壓(ya)(ya)和(he)低(di)壓(ya)(ya)兩(liang)種。高壓(ya)(ya)橡膠(jiao)管(guan)(guan)是在(zai)橡膠(jiao)管(guan)(guan)中心加一層或幾(ji)層織(zhi)造(zao)鋼(gang)絲而成,其承(cheng)壓(ya)(ya)才能可達420X105Pa。低(di)壓(ya)(ya)橡膠(jiao)管(guan)(guan)則以織(zhi)造(zao)棉、麻線替代織(zhi)造(zao)鋼(gang)絲,多(duo)用(yong)于(yu)低(di)壓(ya)(ya)回(hui)油管(guan)(guan)道。
