１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)管由內膠(jiao)(jiao)層、提(ti)(ti)高(gao)層和外(wai)膠(jiao)(jiao)層構成（如圖例），內膠(jiao)(jiao)層立即(ji)與(yu)液(ye)壓(ya)油觸碰，故規定在(zai)長期性(xing)(xing)(xing)(xing)(xing)運行狀(zhuang)態下(xia)不可(ke)受(shou)液(ye)體浸蝕，能(neng)(neng)補漏。在(zai)提(ti)(ti)高(gao)層功效下(xia)會(hui)承擔一定工作壓(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外(wai)，危害性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)的(de)(de)(de)(de)關鍵(jian)要素(su)也(ye)有內膠(jiao)(jiao)層的(de)(de)(de)(de)強(qiang)度、薄(bo)厚(hou)和永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)量。強(qiang)度和永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)量對密封(feng)性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)危害非常(chang)大。一般強(qiang)度高(gao)、縮(suo)(suo)小(xiao)后的(de)(de)(de)(de)永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)量小(xiao)，密封(feng)性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)則越好。一般是(shi)在(zai)７０～８５邵氏硬度，縮(suo)(suo)小(xiao)永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)５０％時(shi)。內膠(jiao)(jiao)層薄(bo)厚(hou)建議(yi)是(shi)為１．５～２．５ｍｍ，太厚(hou)會(hui)在(zai)壓(ya)扣時(shi)提(ti)(ti)升其流(liu)動率，導致不必要的(de)(de)(de)(de)膠(jiao)(jiao)在(zai)接頭(tou)芯(xin)套與(yu)橡膠(jiao)(jiao)軟管的(de)(de)(de)(de)觸碰內孔內沉積，減少商品(pin)(pin)流(liu)通橫截面；過薄(bo)會(hui)在(zai)壓(ya)扣時(shi)被壓(ya)裂。另外(wai)內膠(jiao)(jiao)層壁厚(hou)勻(yun)稱(cheng)性(xing)(xing)(xing)(xing)(xing)也(ye)很(hen)重要。假如薄(bo)厚(hou)不勻(yun)，縮(suo)(suo)小(xiao)后會(hui)導致一面裂斷、一面堆膠(jiao)(jiao)。內膠(jiao)(jiao)層表(biao)層出現的(de)(de)(de)(de)浮銹(xiu)也(ye)是(shi)危害性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)品(pin)(pin)質的(de)(de)(de)(de)關鍵(jian)要素(su)。
２）高壓膠管關鍵借助(zhu)提(ti)高層(ceng)來承(cheng)受力(li)(li)。手(shou)工編織橡膠軟管是(shi)靠膠漿(jiang)與內外黏膠粘(zhan)緊，因為(wei)同一(yi)手(shou)工編織層(ceng)內不(bu)銹(xiu)鋼絲中(zhong)(zhong)(zhong)(zhong)間的(de)互相觸碰，在(zai)(zai)(zai)承(cheng)擔(dan)氣(qi)體壓力(li)(li)的(de)時(shi)候會因分(fen)別伸(shen)縮式不(bu)一(yi)而導致不(bu)銹(xiu)鋼絲彼此(ci)之間的(de)摩(mo)擦(ca)而危害其使(shi)用(yong)性(xing)(xing)能(neng)。而螺旋波紋管是(shi)由盤繞方(fang)位不(bu)一(yi)樣的(de)雙層(ceng)產生(sheng)一(yi)個工作中(zhong)(zhong)(zhong)(zhong)層(ceng)，在(zai)(zai)(zai)雙層(ceng)中(zhong)(zhong)(zhong)(zhong)間有正中(zhong)(zhong)(zhong)(zhong)間膠，因而同一(yi)工作中(zhong)(zhong)(zhong)(zhong)層(ceng)的(de)雙層(ceng)不(bu)銹(xiu)鋼絲中(zhong)(zhong)(zhong)(zhong)間沒有交接(jie)點。因此(ci) 不(bu)容易在(zai)(zai)(zai)承(cheng)擔(dan)氣(qi)體壓力(li)(li)時(shi)同于不(bu)銹(xiu)鋼絲間的(de)交叉(cha)式彎折而產生(sheng)應(ying)力(li)(li)或磨擦(ca)磨壞。故(gu)使(shi)用(yong)性(xing)(xing)能(neng)好，能(neng)承(cheng)擔(dan)髙(gao)壓。
３）高(gao)壓膠(jiao)管的外(wai)膠(jiao)層粘在提高(gao)層上起維護功效(xiao)，一般選用氯丁(ding)膠(jiao)。應留意(yi)避免 其脆化(hua)開裂而危(wei)害全(quan)部橡膠(jiao)軟(ruan)管的使用壽命(ming)。
