１、橡膠軟管總成
1）高(gao)(gao)壓膠(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高(gao)(gao)層(ceng)(ceng)(ceng)和外膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖(tu)例），內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與液(ye)壓油(you)觸碰，故規定(ding)在(zai)(zai)長(chang)期性(xing)(xing)(xing)運行狀態下不(bu)可受液(ye)體浸蝕，能(neng)補漏(lou)。在(zai)(zai)提高(gao)(gao)層(ceng)(ceng)(ceng)功效下會承(cheng)擔一(yi)定(ding)工(gong)作(zuo)壓力。因而，宜選用丁(ding)腈橡(xiang)膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外，危害(hai)(hai)性(xing)(xing)(xing)能(neng)的(de)關鍵要(yao)素也有內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強(qiang)度(du)(du)(du)、薄(bo)(bo)厚和永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形變(bian)量。強(qiang)度(du)(du)(du)和永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形變(bian)量對密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害(hai)(hai)非常大(da)。一(yi)般(ban)強(qiang)度(du)(du)(du)高(gao)(gao)、縮(suo)小(xiao)后的(de)永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形變(bian)量小(xiao)，密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越(yue)好。一(yi)般(ban)是(shi)在(zai)(zai)７０～８５邵氏硬(ying)度(du)(du)(du)，縮(suo)小(xiao)永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形變(bian)５０％時。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)(bo)厚建(jian)議(yi)是(shi)為１．５～２．５ｍｍ，太厚會在(zai)(zai)壓扣(kou)時提升其流動(dong)率，導(dao)致(zhi)不(bu)必要(yao)的(de)膠(jiao)(jiao)(jiao)在(zai)(zai)接(jie)頭(tou)芯套與橡(xiang)膠(jiao)(jiao)(jiao)軟(ruan)管的(de)觸碰內(nei)孔內(nei)沉積，減少商品流通橫截面；過(guo)薄(bo)(bo)會在(zai)(zai)壓扣(kou)時被壓裂(lie)。另外內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻稱性(xing)(xing)(xing)也很重要(yao)。假如薄(bo)(bo)厚不(bu)勻，縮(suo)小(xiao)后會導(dao)致(zhi)一(yi)面裂(lie)斷(duan)、一(yi)面堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)出現的(de)浮銹也是(shi)危害(hai)(hai)性(xing)(xing)(xing)能(neng)品質的(de)關鍵要(yao)素。
２）高(gao)壓膠(jiao)管(guan)關鍵借助提(ti)高(gao)層(ceng)來承受(shou)力(li)。手工編織橡膠(jiao)軟管(guan)是靠膠(jiao)漿與內外黏膠(jiao)粘緊，因(yin)為(wei)同一手工編織層(ceng)內不(bu)(bu)銹鋼(gang)絲(si)(si)中(zhong)(zhong)(zhong)(zhong)間的互相(xiang)觸碰，在(zai)承擔氣(qi)(qi)體(ti)壓力(li)的時候會因(yin)分(fen)別伸(shen)縮式不(bu)(bu)一而(er)導致不(bu)(bu)銹鋼(gang)絲(si)(si)彼此(ci)之間的摩擦而(er)危害其使用(yong)性(xing)(xing)能(neng)。而(er)螺旋波紋管(guan)是由盤繞方(fang)位不(bu)(bu)一樣(yang)的雙(shuang)(shuang)層(ceng)產生(sheng)一個工作中(zhong)(zhong)(zhong)(zhong)層(ceng)，在(zai)雙(shuang)(shuang)層(ceng)中(zhong)(zhong)(zhong)(zhong)間有正中(zhong)(zhong)(zhong)(zhong)間膠(jiao)，因(yin)而(er)同一工作中(zhong)(zhong)(zhong)(zhong)層(ceng)的雙(shuang)(shuang)層(ceng)不(bu)(bu)銹鋼(gang)絲(si)(si)中(zhong)(zhong)(zhong)(zhong)間沒有交接點。因(yin)此(ci) 不(bu)(bu)容易在(zai)承擔氣(qi)(qi)體(ti)壓力(li)時同于不(bu)(bu)銹鋼(gang)絲(si)(si)間的交叉式彎折而(er)產生(sheng)應力(li)或磨擦磨壞(huai)。故(gu)使用(yong)性(xing)(xing)能(neng)好，能(neng)承擔髙(gao)壓。
３）高(gao)壓膠(jiao)管的外膠(jiao)層(ceng)粘在提高(gao)層(ceng)上起維護功(gong)效(xiao)，一般選用氯(lv)丁膠(jiao)。應留意避免 其脆化開(kai)裂而危(wei)害全部橡膠(jiao)軟管的使用壽命。
