１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)管由內(nei)(nei)膠(jiao)層(ceng)(ceng)、提(ti)(ti)高(gao)層(ceng)(ceng)和(he)外(wai)膠(jiao)層(ceng)(ceng)構成（如圖(tu)例），內(nei)(nei)膠(jiao)層(ceng)(ceng)立即與(yu)液壓(ya)油觸碰，故(gu)規定在(zai)(zai)(zai)長(chang)期性(xing)(xing)(xing)(xing)運(yun)行狀(zhuang)態下不可受(shou)液體(ti)浸蝕(shi)，能(neng)補(bu)漏。在(zai)(zai)(zai)提(ti)(ti)高(gao)層(ceng)(ceng)功(gong)效(xiao)下會承擔一(yi)定工(gong)作(zuo)壓(ya)力(li)。因而，宜選用丁(ding)腈橡(xiang)膠(jiao)，除(chu)塑膠(jiao)粒外(wai)，危害(hai)性(xing)(xing)(xing)(xing)能(neng)的(de)(de)關(guan)鍵要素(su)(su)也有(you)內(nei)(nei)膠(jiao)層(ceng)(ceng)的(de)(de)強(qiang)(qiang)度、薄(bo)(bo)厚(hou)和(he)永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變量(liang)。強(qiang)(qiang)度和(he)永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變量(liang)對密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)危害(hai)非常大。一(yi)般(ban)強(qiang)(qiang)度高(gao)、縮(suo)小(xiao)后的(de)(de)永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變量(liang)小(xiao)，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)則越(yue)好。一(yi)般(ban)是(shi)(shi)在(zai)(zai)(zai)７０～８５邵氏硬(ying)度，縮(suo)小(xiao)永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變５０％時(shi)。內(nei)(nei)膠(jiao)層(ceng)(ceng)薄(bo)(bo)厚(hou)建議是(shi)(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)(zai)(zai)壓(ya)扣時(shi)提(ti)(ti)升其流(liu)動率，導(dao)(dao)致不必要的(de)(de)膠(jiao)在(zai)(zai)(zai)接頭芯(xin)套與(yu)橡(xiang)膠(jiao)軟(ruan)管的(de)(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積，減(jian)少商品流(liu)通橫截面(mian)；過薄(bo)(bo)會在(zai)(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂。另外(wai)內(nei)(nei)膠(jiao)層(ceng)(ceng)壁厚(hou)勻(yun)稱性(xing)(xing)(xing)(xing)也很重要。假如薄(bo)(bo)厚(hou)不勻(yun)，縮(suo)小(xiao)后會導(dao)(dao)致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)。內(nei)(nei)膠(jiao)層(ceng)(ceng)表層(ceng)(ceng)出(chu)現的(de)(de)浮銹(xiu)也是(shi)(shi)危害(hai)性(xing)(xing)(xing)(xing)能(neng)品質(zhi)的(de)(de)關(guan)鍵要素(su)(su)。
２）高壓(ya)膠(jiao)(jiao)管關鍵借助提高層(ceng)來承受力(li)。手工(gong)編織橡膠(jiao)(jiao)軟管是靠(kao)膠(jiao)(jiao)漿與(yu)內外黏膠(jiao)(jiao)粘(zhan)緊，因(yin)為同(tong)一手工(gong)編織層(ceng)內不(bu)銹鋼(gang)絲中(zhong)間(jian)的(de)互相觸(chu)碰(peng)，在承擔氣(qi)體(ti)壓(ya)力(li)的(de)時(shi)候會因(yin)分(fen)別伸縮式不(bu)一而(er)導(dao)致不(bu)銹鋼(gang)絲彼此之(zhi)間(jian)的(de)摩擦(ca)而(er)危害其使(shi)(shi)用性能。而(er)螺旋波紋管是由盤(pan)繞方(fang)位不(bu)一樣的(de)雙(shuang)層(ceng)產生一個工(gong)作中(zhong)層(ceng)，在雙(shuang)層(ceng)中(zhong)間(jian)有(you)正中(zhong)間(jian)膠(jiao)(jiao)，因(yin)而(er)同(tong)一工(gong)作中(zhong)層(ceng)的(de)雙(shuang)層(ceng)不(bu)銹鋼(gang)絲中(zhong)間(jian)沒(mei)有(you)交接點。因(yin)此 不(bu)容(rong)易在承擔氣(qi)體(ti)壓(ya)力(li)時(shi)同(tong)于不(bu)銹鋼(gang)絲間(jian)的(de)交叉(cha)式彎折而(er)產生應(ying)力(li)或磨擦(ca)磨壞。故使(shi)(shi)用性能好，能承擔髙壓(ya)。
３）高(gao)壓膠管的外膠層(ceng)(ceng)粘在提(ti)高(gao)層(ceng)(ceng)上(shang)起(qi)維護功效，一般選用氯丁(ding)膠。應留(liu)意避免 其(qi)脆(cui)化開(kai)裂而危害全部橡膠軟管的使用壽命。
