１、橡膠軟管總成
1）高(gao)壓膠(jiao)管由內膠(jiao)層(ceng)(ceng)、提(ti)(ti)高(gao)層(ceng)(ceng)和外(wai)(wai)膠(jiao)層(ceng)(ceng)構(gou)成(cheng)（如圖例），內膠(jiao)層(ceng)(ceng)立即與液壓油觸(chu)碰，故規定在(zai)長期性(xing)(xing)運行狀(zhuang)態下不(bu)可受液體(ti)浸蝕(shi)，能補漏。在(zai)提(ti)(ti)高(gao)層(ceng)(ceng)功效下會承擔一(yi)定工作壓力。因而，宜選用(yong)丁腈橡膠(jiao)，除(chu)塑膠(jiao)粒外(wai)(wai)，危害(hai)(hai)性(xing)(xing)能的(de)關鍵(jian)要素也有內膠(jiao)層(ceng)(ceng)的(de)強(qiang)(qiang)度(du)、薄厚(hou)(hou)和永久性(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)。強(qiang)(qiang)度(du)和永久性(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)對密(mi)(mi)封性(xing)(xing)性(xing)(xing)能危害(hai)(hai)非常大。一(yi)般(ban)強(qiang)(qiang)度(du)高(gao)、縮(suo)(suo)小后(hou)的(de)永久性(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)小，密(mi)(mi)封性(xing)(xing)性(xing)(xing)能則越好(hao)。一(yi)般(ban)是(shi)在(zai)７０～８５邵氏硬(ying)度(du)，縮(suo)(suo)小永久性(xing)(xing)形(xing)變(bian)(bian)５０％時(shi)(shi)(shi)。內膠(jiao)層(ceng)(ceng)薄厚(hou)(hou)建議是(shi)為１．５～２．５ｍｍ，太厚(hou)(hou)會在(zai)壓扣(kou)時(shi)(shi)(shi)提(ti)(ti)升其流動率(lv)，導(dao)致不(bu)必(bi)要的(de)膠(jiao)在(zai)接頭芯套與橡膠(jiao)軟管的(de)觸(chu)碰內孔內沉積(ji)，減少商品流通(tong)橫截面(mian)；過薄會在(zai)壓扣(kou)時(shi)(shi)(shi)被壓裂。另外(wai)(wai)內膠(jiao)層(ceng)(ceng)壁(bi)厚(hou)(hou)勻(yun)稱性(xing)(xing)也很重要。假如薄厚(hou)(hou)不(bu)勻(yun)，縮(suo)(suo)小后(hou)會導(dao)致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)。內膠(jiao)層(ceng)(ceng)表(biao)層(ceng)(ceng)出現的(de)浮銹也是(shi)危害(hai)(hai)性(xing)(xing)能品質的(de)關鍵(jian)要素。
２）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)管關鍵(jian)借(jie)助提高層(ceng)(ceng)(ceng)來承受力。手(shou)工(gong)編(bian)(bian)織(zhi)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟(ruan)管是(shi)靠膠(jiao)(jiao)(jiao)(jiao)漿(jiang)與內外黏膠(jiao)(jiao)(jiao)(jiao)粘緊，因(yin)為同一(yi)手(shou)工(gong)編(bian)(bian)織(zhi)層(ceng)(ceng)(ceng)內不(bu)(bu)(bu)銹鋼(gang)(gang)(gang)(gang)絲(si)中間(jian)(jian)的互相觸(chu)碰，在(zai)承擔氣(qi)體壓(ya)力的時候(hou)會因(yin)分別伸(shen)縮式(shi)不(bu)(bu)(bu)一(yi)而(er)導致不(bu)(bu)(bu)銹鋼(gang)(gang)(gang)(gang)絲(si)彼此(ci)之間(jian)(jian)的摩擦而(er)危害其使(shi)用性能(neng)。而(er)螺旋波紋管是(shi)由盤繞方位不(bu)(bu)(bu)一(yi)樣的雙層(ceng)(ceng)(ceng)產生(sheng)(sheng)一(yi)個工(gong)作中層(ceng)(ceng)(ceng)，在(zai)雙層(ceng)(ceng)(ceng)中間(jian)(jian)有正(zheng)中間(jian)(jian)膠(jiao)(jiao)(jiao)(jiao)，因(yin)而(er)同一(yi)工(gong)作中層(ceng)(ceng)(ceng)的雙層(ceng)(ceng)(ceng)不(bu)(bu)(bu)銹鋼(gang)(gang)(gang)(gang)絲(si)中間(jian)(jian)沒有交接點。因(yin)此(ci) 不(bu)(bu)(bu)容易(yi)在(zai)承擔氣(qi)體壓(ya)力時同于(yu)不(bu)(bu)(bu)銹鋼(gang)(gang)(gang)(gang)絲(si)間(jian)(jian)的交叉式(shi)彎折而(er)產生(sheng)(sheng)應力或磨(mo)擦磨(mo)壞(huai)。故使(shi)用性能(neng)好，能(neng)承擔髙壓(ya)。
３）高壓(ya)膠(jiao)管的外膠(jiao)層粘(zhan)在提高層上起維護功(gong)效，一般選用氯丁(ding)膠(jiao)。應(ying)留意避免 其脆(cui)化開裂而(er)危害(hai)全(quan)部橡膠(jiao)軟管的使用壽命(ming)。
