１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)(ceng)和外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖例(li)），內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與(yu)液壓(ya)(ya)油觸碰，故規定在長期性(xing)(xing)運行狀(zhuang)態下(xia)不可受液體浸蝕，能(neng)補漏。在提(ti)高(gao)層(ceng)(ceng)(ceng)功(gong)效下(xia)會承擔一定工作壓(ya)(ya)力。因(yin)而，宜選用丁(ding)腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒(li)外，危(wei)害(hai)性(xing)(xing)能(neng)的(de)關鍵要素也有內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強度(du)(du)、薄(bo)厚(hou)和永久(jiu)(jiu)性(xing)(xing)形變(bian)(bian)(bian)量。強度(du)(du)和永久(jiu)(jiu)性(xing)(xing)形變(bian)(bian)(bian)量對密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)危(wei)害(hai)非(fei)常大。一般強度(du)(du)高(gao)、縮(suo)小(xiao)后(hou)的(de)永久(jiu)(jiu)性(xing)(xing)形變(bian)(bian)(bian)量小(xiao)，密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)則越好(hao)。一般是在７０～８５邵(shao)氏硬度(du)(du)，縮(suo)小(xiao)永久(jiu)(jiu)性(xing)(xing)形變(bian)(bian)(bian)５０％時(shi)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚(hou)建(jian)議(yi)是為１．５～２．５ｍｍ，太厚(hou)會在壓(ya)(ya)扣時(shi)提(ti)升其流動(dong)率，導致(zhi)不必要的(de)膠(jiao)(jiao)(jiao)(jiao)在接頭芯套(tao)與(yu)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰內孔(kong)內沉積，減少商品流通橫截面(mian)；過(guo)薄(bo)會在壓(ya)(ya)扣時(shi)被壓(ya)(ya)裂。另外內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚(hou)勻稱(cheng)性(xing)(xing)也很(hen)重(zhong)要。假(jia)如薄(bo)厚(hou)不勻，縮(suo)小(xiao)后(hou)會導致(zhi)一面(mian)裂斷、一面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)出現的(de)浮銹也是危(wei)害(hai)性(xing)(xing)能(neng)品質(zhi)的(de)關鍵要素。
２）高壓膠(jiao)(jiao)管關鍵借(jie)助提高層(ceng)(ceng)(ceng)來(lai)承受力。手(shou)工(gong)編織橡(xiang)膠(jiao)(jiao)軟(ruan)管是靠膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊，因(yin)為(wei)同(tong)一手(shou)工(gong)編織層(ceng)(ceng)(ceng)內不(bu)(bu)銹(xiu)鋼(gang)絲(si)中間(jian)(jian)的互相觸碰，在(zai)(zai)承擔氣體壓力的時候會因(yin)分別(bie)伸(shen)縮式(shi)不(bu)(bu)一而(er)(er)導(dao)致不(bu)(bu)銹(xiu)鋼(gang)絲(si)彼此之間(jian)(jian)的摩擦而(er)(er)危害其使(shi)用性能。而(er)(er)螺旋波紋(wen)管是由(you)盤繞方位不(bu)(bu)一樣(yang)的雙(shuang)層(ceng)(ceng)(ceng)產生(sheng)一個工(gong)作中層(ceng)(ceng)(ceng)，在(zai)(zai)雙(shuang)層(ceng)(ceng)(ceng)中間(jian)(jian)有(you)正中間(jian)(jian)膠(jiao)(jiao)，因(yin)而(er)(er)同(tong)一工(gong)作中層(ceng)(ceng)(ceng)的雙(shuang)層(ceng)(ceng)(ceng)不(bu)(bu)銹(xiu)鋼(gang)絲(si)中間(jian)(jian)沒(mei)有(you)交接點(dian)。因(yin)此 不(bu)(bu)容易在(zai)(zai)承擔氣體壓力時同(tong)于不(bu)(bu)銹(xiu)鋼(gang)絲(si)間(jian)(jian)的交叉式(shi)彎折而(er)(er)產生(sheng)應力或(huo)磨擦磨壞(huai)。故使(shi)用性能好，能承擔髙壓。
３）高壓膠管的外膠層粘在提高層上起維護功(gong)效(xiao)，一(yi)般選用氯丁膠。應留意(yi)避免(mian) 其脆化開裂而危害全部橡膠軟管的使用壽命。
