１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)由(you)內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液壓(ya)(ya)油觸(chu)碰(peng)，故(gu)規定(ding)在(zai)(zai)(zai)長期性(xing)(xing)運行狀態下不(bu)可受液體浸(jin)蝕，能(neng)(neng)補漏。在(zai)(zai)(zai)提(ti)高(gao)層(ceng)(ceng)功效下會(hui)承擔一(yi)定(ding)工作壓(ya)(ya)力。因而，宜選用(yong)丁腈(jing)橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)，危(wei)害(hai)性(xing)(xing)能(neng)(neng)的(de)(de)關(guan)鍵(jian)要(yao)素(su)也(ye)有內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度(du)(du)、薄(bo)(bo)厚(hou)和永(yong)久性(xing)(xing)形(xing)變(bian)量(liang)。強(qiang)度(du)(du)和永(yong)久性(xing)(xing)形(xing)變(bian)量(liang)對密封性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害(hai)非(fei)常大。一(yi)般(ban)強(qiang)度(du)(du)高(gao)、縮小后的(de)(de)永(yong)久性(xing)(xing)形(xing)變(bian)量(liang)小，密封性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好(hao)。一(yi)般(ban)是(shi)在(zai)(zai)(zai)７０～８５邵氏(shi)硬(ying)度(du)(du)，縮小永(yong)久性(xing)(xing)形(xing)變(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)(bo)厚(hou)建(jian)議是(shi)為１．５～２．５ｍｍ，太厚(hou)會(hui)在(zai)(zai)(zai)壓(ya)(ya)扣(kou)時(shi)提(ti)升其流(liu)動率，導(dao)致不(bu)必(bi)要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)(zai)接頭(tou)芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸(chu)碰(peng)內(nei)孔內(nei)沉積，減少商品(pin)流(liu)通橫(heng)截面(mian)；過薄(bo)(bo)會(hui)在(zai)(zai)(zai)壓(ya)(ya)扣(kou)時(shi)被壓(ya)(ya)裂。另外(wai)內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)也(ye)很重(zhong)要(yao)。假如薄(bo)(bo)厚(hou)不(bu)勻，縮小后會(hui)導(dao)致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表(biao)層(ceng)(ceng)出(chu)現的(de)(de)浮銹也(ye)是(shi)危(wei)害(hai)性(xing)(xing)能(neng)(neng)品(pin)質的(de)(de)關(guan)鍵(jian)要(yao)素(su)。
２）高(gao)壓(ya)膠(jiao)管關鍵借助提高(gao)層(ceng)(ceng)(ceng)來承(cheng)受力(li)。手(shou)工(gong)編織(zhi)橡膠(jiao)軟管是靠膠(jiao)漿(jiang)與內外黏(nian)膠(jiao)粘緊，因(yin)為同一手(shou)工(gong)編織(zhi)層(ceng)(ceng)(ceng)內不(bu)(bu)銹(xiu)(xiu)鋼絲(si)中(zhong)間(jian)(jian)的(de)互相(xiang)觸碰，在承(cheng)擔氣體壓(ya)力(li)的(de)時候會因(yin)分別伸縮式(shi)不(bu)(bu)一而(er)(er)導(dao)致(zhi)不(bu)(bu)銹(xiu)(xiu)鋼絲(si)彼此(ci)(ci)之(zhi)間(jian)(jian)的(de)摩擦而(er)(er)危害(hai)其使用(yong)性能。而(er)(er)螺旋(xuan)波紋管是由盤繞(rao)方位(wei)不(bu)(bu)一樣(yang)的(de)雙層(ceng)(ceng)(ceng)產生(sheng)一個工(gong)作中(zhong)層(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)中(zhong)間(jian)(jian)有正中(zhong)間(jian)(jian)膠(jiao)，因(yin)而(er)(er)同一工(gong)作中(zhong)層(ceng)(ceng)(ceng)的(de)雙層(ceng)(ceng)(ceng)不(bu)(bu)銹(xiu)(xiu)鋼絲(si)中(zhong)間(jian)(jian)沒有交接點。因(yin)此(ci)(ci) 不(bu)(bu)容易在承(cheng)擔氣體壓(ya)力(li)時同于不(bu)(bu)銹(xiu)(xiu)鋼絲(si)間(jian)(jian)的(de)交叉式(shi)彎折而(er)(er)產生(sheng)應力(li)或磨(mo)擦磨(mo)壞。故使用(yong)性能好(hao)，能承(cheng)擔髙(gao)壓(ya)。
３）高壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層粘在提(ti)高層上起(qi)維護(hu)功效，一般選用(yong)氯丁膠(jiao)(jiao)。應留(liu)意避(bi)免 其脆(cui)化開裂而危害(hai)全部橡(xiang)膠(jiao)(jiao)軟(ruan)管的使用(yong)壽命。
