１、橡膠軟管總成
1）高壓(ya)(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高層(ceng)(ceng)和(he)(he)外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如圖(tu)例），內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立(li)即與液(ye)壓(ya)(ya)(ya)油(you)觸碰，故規定在(zai)長(chang)期性(xing)(xing)(xing)運行狀態下不(bu)可(ke)受液(ye)體浸蝕(shi)，能(neng)(neng)(neng)補(bu)漏。在(zai)提(ti)高層(ceng)(ceng)功效下會承(cheng)擔一(yi)定工作壓(ya)(ya)(ya)力(li)。因而，宜(yi)選(xuan)用(yong)丁(ding)腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外(wai)(wai)，危害性(xing)(xing)(xing)能(neng)(neng)(neng)的(de)關鍵(jian)要素也(ye)有內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)強(qiang)度(du)、薄厚(hou)和(he)(he)永久(jiu)性(xing)(xing)(xing)形變(bian)量(liang)。強(qiang)度(du)和(he)(he)永久(jiu)性(xing)(xing)(xing)形變(bian)量(liang)對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)(neng)危害非常大。一(yi)般強(qiang)度(du)高、縮小后(hou)的(de)永久(jiu)性(xing)(xing)(xing)形變(bian)量(liang)小，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)(neng)則越好。一(yi)般是(shi)(shi)在(zai)７０～８５邵(shao)氏(shi)硬(ying)度(du)，縮小永久(jiu)性(xing)(xing)(xing)形變(bian)５０％時。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄厚(hou)建議是(shi)(shi)為１．５～２．５ｍｍ，太厚(hou)會在(zai)壓(ya)(ya)(ya)扣(kou)時提(ti)升(sheng)其流動率，導(dao)致(zhi)不(bu)必(bi)要的(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯(xin)套與橡膠(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰內孔內沉(chen)積(ji)，減少(shao)商(shang)品流通橫截面(mian)；過薄會在(zai)壓(ya)(ya)(ya)扣(kou)時被壓(ya)(ya)(ya)裂。另(ling)外(wai)(wai)內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱(cheng)性(xing)(xing)(xing)也(ye)很重要。假(jia)如薄厚(hou)不(bu)勻，縮小后(hou)會導(dao)致(zhi)一(yi)面(mian)裂斷(duan)、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)浮(fu)銹(xiu)也(ye)是(shi)(shi)危害性(xing)(xing)(xing)能(neng)(neng)(neng)品質的(de)關鍵(jian)要素。
２）高壓(ya)膠管關鍵借助提高層(ceng)(ceng)(ceng)來承(cheng)(cheng)受力。手工編織橡膠軟管是靠膠漿與(yu)內(nei)外(wai)黏膠粘緊，因(yin)為(wei)同一(yi)手工編織層(ceng)(ceng)(ceng)內(nei)不(bu)銹鋼(gang)絲中(zhong)(zhong)間的(de)互相(xiang)觸碰，在(zai)承(cheng)(cheng)擔氣(qi)體壓(ya)力的(de)時候會因(yin)分(fen)別伸(shen)縮(suo)式不(bu)一(yi)而導致(zhi)不(bu)銹鋼(gang)絲彼此之間的(de)摩擦(ca)而危(wei)害其使用(yong)(yong)性能(neng)。而螺旋波紋管是由盤繞方位(wei)不(bu)一(yi)樣的(de)雙(shuang)層(ceng)(ceng)(ceng)產生一(yi)個(ge)工作中(zhong)(zhong)層(ceng)(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)(ceng)中(zhong)(zhong)間有正中(zhong)(zhong)間膠，因(yin)而同一(yi)工作中(zhong)(zhong)層(ceng)(ceng)(ceng)的(de)雙(shuang)層(ceng)(ceng)(ceng)不(bu)銹鋼(gang)絲中(zhong)(zhong)間沒有交(jiao)接點。因(yin)此 不(bu)容易(yi)在(zai)承(cheng)(cheng)擔氣(qi)體壓(ya)力時同于不(bu)銹鋼(gang)絲間的(de)交(jiao)叉式彎折(zhe)而產生應力或磨(mo)擦(ca)磨(mo)壞。故(gu)使用(yong)(yong)性能(neng)好，能(neng)承(cheng)(cheng)擔髙壓(ya)。
３）高(gao)(gao)壓膠管(guan)的外膠層粘在提(ti)高(gao)(gao)層上起(qi)維護功效，一般選用氯丁膠。應留意避免 其脆化開裂而危害全部橡膠軟管(guan)的使用壽命。
