１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)和外膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構(gou)成（如圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液壓(ya)(ya)油觸(chu)碰，故規定(ding)在長期性(xing)運行(xing)狀態(tai)下(xia)不可受液體浸蝕(shi)，能補(bu)漏。在提(ti)高(gao)層(ceng)(ceng)功效下(xia)會承擔(dan)一定(ding)工作壓(ya)(ya)力。因而，宜選(xuan)用(yong)丁(ding)腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)外，危(wei)害性(xing)能的(de)關鍵要(yao)素也有內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)強度、薄(bo)厚和永久(jiu)性(xing)形變量。強度和永久(jiu)性(xing)形變量對密封(feng)性(xing)性(xing)能危(wei)害非常大。一般強度高(gao)、縮小(xiao)(xiao)后(hou)的(de)永久(jiu)性(xing)形變量小(xiao)(xiao)，密封(feng)性(xing)性(xing)能則(ze)越(yue)好。一般是(shi)在７０～８５邵氏硬度，縮小(xiao)(xiao)永久(jiu)性(xing)形變５０％時。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚建議是(shi)為１．５～２．５ｍｍ，太(tai)厚會在壓(ya)(ya)扣(kou)時提(ti)升其(qi)流動率，導致(zhi)不必要(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在接頭(tou)芯套與橡膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)觸(chu)碰內(nei)孔內(nei)沉積，減(jian)少商(shang)品(pin)(pin)流通橫(heng)截面(mian)；過(guo)薄(bo)會在壓(ya)(ya)扣(kou)時被(bei)壓(ya)(ya)裂(lie)。另外內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚勻稱性(xing)也很重要(yao)。假如薄(bo)厚不勻，縮小(xiao)(xiao)后(hou)會導致(zhi)一面(mian)裂(lie)斷、一面(mian)堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表(biao)層(ceng)(ceng)出(chu)現的(de)浮銹也是(shi)危(wei)害性(xing)能品(pin)(pin)質的(de)關鍵要(yao)素。
２）高壓(ya)膠(jiao)(jiao)管關鍵借助提(ti)高層來承(cheng)受力。手(shou)(shou)工(gong)(gong)編(bian)(bian)織橡(xiang)膠(jiao)(jiao)軟(ruan)管是靠膠(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)粘緊，因(yin)(yin)為(wei)同一手(shou)(shou)工(gong)(gong)編(bian)(bian)織層內(nei)不(bu)銹(xiu)鋼絲(si)中(zhong)(zhong)間(jian)的(de)(de)互(hu)相觸碰，在(zai)承(cheng)擔氣(qi)體壓(ya)力的(de)(de)時候(hou)會因(yin)(yin)分別(bie)伸縮式不(bu)一而導致不(bu)銹(xiu)鋼絲(si)彼(bi)此(ci)之間(jian)的(de)(de)摩擦(ca)而危害其(qi)使用(yong)性(xing)能(neng)。而螺旋波紋管是由盤繞方(fang)位不(bu)一樣的(de)(de)雙(shuang)(shuang)(shuang)層產(chan)生一個工(gong)(gong)作(zuo)中(zhong)(zhong)層，在(zai)雙(shuang)(shuang)(shuang)層中(zhong)(zhong)間(jian)有(you)正(zheng)中(zhong)(zhong)間(jian)膠(jiao)(jiao)，因(yin)(yin)而同一工(gong)(gong)作(zuo)中(zhong)(zhong)層的(de)(de)雙(shuang)(shuang)(shuang)層不(bu)銹(xiu)鋼絲(si)中(zhong)(zhong)間(jian)沒有(you)交接點。因(yin)(yin)此(ci) 不(bu)容易在(zai)承(cheng)擔氣(qi)體壓(ya)力時同于不(bu)銹(xiu)鋼絲(si)間(jian)的(de)(de)交叉式彎折而產(chan)生應力或(huo)磨(mo)擦(ca)磨(mo)壞。故使用(yong)性(xing)能(neng)好，能(neng)承(cheng)擔髙(gao)壓(ya)。
３）高(gao)(gao)壓膠(jiao)管的外膠(jiao)層粘在提高(gao)(gao)層上起維護功效，一(yi)般選用氯丁(ding)膠(jiao)。應留意避免 其脆化開(kai)裂而危(wei)害全部橡膠(jiao)軟管的使用壽(shou)命。
