耐油膠管技術資料
耐油膠管的內膠層直接承受輸送介質的磨損、侵蝕,且防止其泄漏;外膠層保護骨架層不受外界的損傷和侵蝕;骨架層是膠管的承壓層,賦予管體強度和剛度。柴汽油耐油膠管的工作壓力取決于骨架層的材料和結構。膠管按其骨架層材料和結構(見圖)可分為全膠膠管(無織物材料)、耐油膠管(骨架(jia)層(ceng)(ceng)(ceng)為布層(ceng)(ceng)(ceng),圖(tu)a)、吸(xi)(xi)引膠(jiao)(jiao)管(guan)(guan)(guan)(布層(ceng)(ceng)(ceng)外還有(you)一層(ceng)(ceng)(ceng)金屬螺旋線,圖(tu)b)、編織(zhi)(zhi)膠(jiao)(jiao)管(guan)(guan)(guan)(骨架(jia)層(ceng)(ceng)(ceng)為編織(zhi)(zhi)的(de)鋼(gang)絲或織(zhi)(zhi)物,圖(tu)c)、纏(chan)繞膠(jiao)(jiao)管(guan)(guan)(guan)(骨架(jia)層(ceng)(ceng)(ceng)為鋼(gang)絲或線繩纏(chan)繞層(ceng)(ceng)(ceng),圖(tu)d)、針織(zhi)(zhi)膠(jiao)(jiao)管(guan)(guan)(guan)(骨架(jia)層(ceng)(ceng)(ceng)為針織(zhi)(zhi)物,圖(tu)e)、短纖維(wei)膠(jiao)(jiao)管(guan)(guan)(guan)(短纖維(wei)與橡(xiang)膠(jiao)(jiao)共混壓而成(cheng))。其中(zhong)吸(xi)(xi)引膠(jiao)(jiao)管(guan)(guan)(guan)在(zai)負壓下工(gong)作,鋼(gang)絲編織(zhi)(zhi)膠(jiao)(jiao)管(guan)(guan)(guan)或纏(chan)繞膠(jiao)(jiao)管(guan)(guan)(guan)能(neng)承受80~600MPa乃至更高的(de)壓力
