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)(jia)(jia)層(ceng)(ceng)為布層(ceng)(ceng),圖(tu)a)、吸引(yin)膠(jiao)管(guan)(guan)(布層(ceng)(ceng)外還有(you)一層(ceng)(ceng)金屬(shu)螺旋線(xian),圖(tu)b)、編(bian)織(zhi)(zhi)膠(jiao)管(guan)(guan)(骨架(jia)(jia)(jia)層(ceng)(ceng)為編(bian)織(zhi)(zhi)的(de)鋼(gang)絲或織(zhi)(zhi)物,圖(tu)c)、纏(chan)繞膠(jiao)管(guan)(guan)(骨架(jia)(jia)(jia)層(ceng)(ceng)為鋼(gang)絲或線(xian)繩纏(chan)繞層(ceng)(ceng),圖(tu)d)、針織(zhi)(zhi)膠(jiao)管(guan)(guan)(骨架(jia)(jia)(jia)層(ceng)(ceng)為針織(zhi)(zhi)物,圖(tu)e)、短纖維膠(jiao)管(guan)(guan)(短纖維與橡膠(jiao)共混壓(ya)而成(cheng))。其中(zhong)吸引(yin)膠(jiao)管(guan)(guan)在負壓(ya)下工作,鋼(gang)絲編(bian)織(zhi)(zhi)膠(jiao)管(guan)(guan)或纏(chan)繞膠(jiao)管(guan)(guan)能承(cheng)受80~600MPa乃至更(geng)高的(de)壓(ya)力
