１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提高層(ceng)(ceng)和(he)外(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構(gou)成（如圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立(li)即與液(ye)壓(ya)油觸(chu)(chu)碰(peng)(peng)，故規定在(zai)長期性(xing)(xing)(xing)(xing)(xing)運行狀態下不(bu)可受液(ye)體浸蝕，能(neng)(neng)(neng)補漏(lou)。在(zai)提高層(ceng)(ceng)功效下會承(cheng)擔一(yi)定工(gong)作壓(ya)力。因而，宜選用丁(ding)腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)粒外(wai)，危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)的(de)(de)關鍵要素也有(you)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度(du)(du)、薄厚(hou)和(he)永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)。強(qiang)度(du)(du)和(he)永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)對密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)危(wei)害(hai)非常大。一(yi)般強(qiang)度(du)(du)高、縮(suo)(suo)小后的(de)(de)永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)小，密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)則越好。一(yi)般是(shi)在(zai)７０～８５邵氏硬度(du)(du)，縮(suo)(suo)小永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄厚(hou)建議(yi)是(shi)為１．５～２．５ｍｍ，太厚(hou)會在(zai)壓(ya)扣時(shi)提升其(qi)流(liu)動率，導致(zhi)(zhi)不(bu)必(bi)要的(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)接頭(tou)芯套與橡膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)觸(chu)(chu)碰(peng)(peng)內(nei)孔內(nei)沉積，減少商品(pin)流(liu)通橫截面；過薄會在(zai)壓(ya)扣時(shi)被壓(ya)裂(lie)。另外(wai)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)(xing)(xing)也很(hen)重要。假如薄厚(hou)不(bu)勻，縮(suo)(suo)小后會導致(zhi)(zhi)一(yi)面裂(lie)斷、一(yi)面堆(dui)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)浮銹也是(shi)危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)(neng)品(pin)質的(de)(de)關鍵要素。
２）高(gao)壓(ya)膠管關鍵借助提(ti)高(gao)層(ceng)(ceng)來承受力(li)(li)。手工編(bian)織橡膠軟管是靠膠漿與內外(wai)黏膠粘緊，因(yin)為(wei)同(tong)一手工編(bian)織層(ceng)(ceng)內不(bu)(bu)銹鋼絲(si)(si)中(zhong)間(jian)的(de)互相觸碰(peng)，在(zai)(zai)承擔氣(qi)體壓(ya)力(li)(li)的(de)時(shi)候會因(yin)分別伸縮式不(bu)(bu)一而導致不(bu)(bu)銹鋼絲(si)(si)彼此(ci)之(zhi)間(jian)的(de)摩(mo)擦(ca)而危害(hai)其使(shi)用(yong)性(xing)能(neng)(neng)。而螺旋波紋管是由(you)盤繞方位不(bu)(bu)一樣的(de)雙(shuang)層(ceng)(ceng)產(chan)生一個工作(zuo)(zuo)中(zhong)層(ceng)(ceng)，在(zai)(zai)雙(shuang)層(ceng)(ceng)中(zhong)間(jian)有正中(zhong)間(jian)膠，因(yin)而同(tong)一工作(zuo)(zuo)中(zhong)層(ceng)(ceng)的(de)雙(shuang)層(ceng)(ceng)不(bu)(bu)銹鋼絲(si)(si)中(zhong)間(jian)沒(mei)有交接點。因(yin)此(ci) 不(bu)(bu)容易在(zai)(zai)承擔氣(qi)體壓(ya)力(li)(li)時(shi)同(tong)于(yu)不(bu)(bu)銹鋼絲(si)(si)間(jian)的(de)交叉式彎折而產(chan)生應力(li)(li)或磨擦(ca)磨壞。故(gu)使(shi)用(yong)性(xing)能(neng)(neng)好，能(neng)(neng)承擔髙壓(ya)。
３）高壓膠(jiao)(jiao)管的(de)(de)外膠(jiao)(jiao)層(ceng)(ceng)粘在提高層(ceng)(ceng)上(shang)起維(wei)護功效，一般選用氯(lv)丁膠(jiao)(jiao)。應留(liu)意(yi)避免(mian) 其脆化(hua)開裂而危害全部橡膠(jiao)(jiao)軟管的(de)(de)使用壽命。
