１、橡膠軟管總成
1）高壓(ya)(ya)膠(jiao)(jiao)管由內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)(ceng)和(he)外(wai)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構(gou)成（如圖例），內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即(ji)與(yu)液壓(ya)(ya)油觸碰(peng)，故規定在(zai)長(chang)期(qi)性(xing)運(yun)行狀態(tai)下不(bu)可受液體浸蝕，能補漏。在(zai)提(ti)高層(ceng)(ceng)(ceng)(ceng)功效下會(hui)承擔(dan)一定工作壓(ya)(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外(wai)，危(wei)害性(xing)能的(de)關鍵要(yao)(yao)素(su)也(ye)有內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)強度、薄(bo)厚和(he)永(yong)(yong)久(jiu)(jiu)性(xing)形變量(liang)(liang)。強度和(he)永(yong)(yong)久(jiu)(jiu)性(xing)形變量(liang)(liang)對(dui)密封(feng)性(xing)性(xing)能危(wei)害非常大。一般強度高、縮小(xiao)(xiao)后(hou)的(de)永(yong)(yong)久(jiu)(jiu)性(xing)形變量(liang)(liang)小(xiao)(xiao)，密封(feng)性(xing)性(xing)能則越好。一般是(shi)在(zai)７０～８５邵氏硬度，縮小(xiao)(xiao)永(yong)(yong)久(jiu)(jiu)性(xing)形變５０％時。內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄(bo)厚建議是(shi)為(wei)１．５～２．５ｍｍ，太厚會(hui)在(zai)壓(ya)(ya)扣時提(ti)升其流(liu)動率，導致不(bu)必要(yao)(yao)的(de)膠(jiao)(jiao)在(zai)接頭芯(xin)套與(yu)橡膠(jiao)(jiao)軟管的(de)觸碰(peng)內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商品流(liu)通(tong)橫截面；過(guo)薄(bo)會(hui)在(zai)壓(ya)(ya)扣時被壓(ya)(ya)裂(lie)。另外(wai)內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚勻稱性(xing)也(ye)很重要(yao)(yao)。假(jia)如薄(bo)厚不(bu)勻，縮小(xiao)(xiao)后(hou)會(hui)導致一面裂(lie)斷、一面堆膠(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)(ceng)出現的(de)浮銹也(ye)是(shi)危(wei)害性(xing)能品質的(de)關鍵要(yao)(yao)素(su)。
２）高(gao)壓膠管關鍵借(jie)助提高(gao)層(ceng)(ceng)來承(cheng)(cheng)受力。手(shou)工編(bian)織(zhi)橡膠軟管是(shi)靠膠漿與內外黏膠粘緊，因(yin)為同一手(shou)工編(bian)織(zhi)層(ceng)(ceng)內不(bu)銹(xiu)鋼絲(si)中間(jian)(jian)的(de)(de)(de)互相觸(chu)碰，在(zai)(zai)承(cheng)(cheng)擔氣(qi)(qi)體(ti)壓力的(de)(de)(de)時(shi)候會因(yin)分別伸縮式(shi)不(bu)一而導致(zhi)不(bu)銹(xiu)鋼絲(si)彼此(ci)之(zhi)間(jian)(jian)的(de)(de)(de)摩擦而危害其使(shi)用性能。而螺旋波紋管是(shi)由盤繞方位不(bu)一樣的(de)(de)(de)雙(shuang)(shuang)層(ceng)(ceng)產(chan)生(sheng)一個(ge)工作中層(ceng)(ceng)，在(zai)(zai)雙(shuang)(shuang)層(ceng)(ceng)中間(jian)(jian)有正中間(jian)(jian)膠，因(yin)而同一工作中層(ceng)(ceng)的(de)(de)(de)雙(shuang)(shuang)層(ceng)(ceng)不(bu)銹(xiu)鋼絲(si)中間(jian)(jian)沒(mei)有交(jiao)接點。因(yin)此(ci) 不(bu)容易在(zai)(zai)承(cheng)(cheng)擔氣(qi)(qi)體(ti)壓力時(shi)同于不(bu)銹(xiu)鋼絲(si)間(jian)(jian)的(de)(de)(de)交(jiao)叉(cha)式(shi)彎折而產(chan)生(sheng)應力或磨(mo)擦磨(mo)壞(huai)。故使(shi)用性能好，能承(cheng)(cheng)擔髙壓。
３）高壓(ya)膠(jiao)管(guan)的(de)(de)外(wai)膠(jiao)層(ceng)粘在(zai)提高層(ceng)上(shang)起(qi)維護(hu)功效(xiao)，一般(ban)選用氯丁(ding)膠(jiao)。應留意避(bi)免 其(qi)脆化開裂(lie)而危(wei)害全部橡膠(jiao)軟管(guan)的(de)(de)使用壽命。
