１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)管(guan)由內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)(ceng)和外(wai)(wai)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如圖例），內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即與液壓(ya)油觸碰(peng)，故規(gui)定在(zai)長期性(xing)(xing)運行狀(zhuang)態下(xia)不可受液體浸(jin)蝕，能(neng)補漏。在(zai)提(ti)高層(ceng)(ceng)(ceng)(ceng)功效下(xia)會承擔一定工作(zuo)壓(ya)力。因而，宜選(xuan)用(yong)丁腈橡膠(jiao)(jiao)，除塑(su)膠(jiao)(jiao)粒外(wai)(wai)，危害性(xing)(xing)能(neng)的(de)關(guan)鍵(jian)要素也(ye)有內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)強度(du)(du)、薄厚和永久(jiu)(jiu)(jiu)性(xing)(xing)形變量。強度(du)(du)和永久(jiu)(jiu)(jiu)性(xing)(xing)形變量對密(mi)封性(xing)(xing)性(xing)(xing)能(neng)危害非常(chang)大。一般強度(du)(du)高、縮小(xiao)后的(de)永久(jiu)(jiu)(jiu)性(xing)(xing)形變量小(xiao)，密(mi)封性(xing)(xing)性(xing)(xing)能(neng)則越(yue)好。一般是(shi)在(zai)７０～８５邵氏硬度(du)(du)，縮小(xiao)永久(jiu)(jiu)(jiu)性(xing)(xing)形變５０％時。內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄厚建議是(shi)為１．５～２．５ｍｍ，太(tai)厚會在(zai)壓(ya)扣(kou)時提(ti)升(sheng)其流(liu)動率，導(dao)致(zhi)不必要的(de)膠(jiao)(jiao)在(zai)接頭芯套與橡膠(jiao)(jiao)軟管(guan)的(de)觸碰(peng)內孔內沉積(ji)，減(jian)少(shao)商(shang)品流(liu)通(tong)橫截面(mian)；過(guo)薄會在(zai)壓(ya)扣(kou)時被壓(ya)裂。另外(wai)(wai)內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚勻稱性(xing)(xing)也(ye)很重要。假如薄厚不勻，縮小(xiao)后會導(dao)致(zhi)一面(mian)裂斷、一面(mian)堆(dui)膠(jiao)(jiao)。內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)(ceng)出現的(de)浮銹也(ye)是(shi)危害性(xing)(xing)能(neng)品質(zhi)的(de)關(guan)鍵(jian)要素。
２）高壓膠(jiao)管關鍵借助提高層(ceng)(ceng)(ceng)來承(cheng)(cheng)受力。手(shou)(shou)工(gong)(gong)編織橡膠(jiao)軟管是靠膠(jiao)漿與內外黏膠(jiao)粘(zhan)緊，因為同一(yi)(yi)手(shou)(shou)工(gong)(gong)編織層(ceng)(ceng)(ceng)內不銹(xiu)鋼絲(si)中間(jian)(jian)(jian)的(de)(de)互相(xiang)觸碰，在(zai)承(cheng)(cheng)擔氣(qi)體壓力的(de)(de)時候(hou)會(hui)因分別伸縮式不一(yi)(yi)而導致不銹(xiu)鋼絲(si)彼此之間(jian)(jian)(jian)的(de)(de)摩擦(ca)而危害其使用性(xing)能(neng)。而螺旋(xuan)波紋管是由盤繞(rao)方位不一(yi)(yi)樣的(de)(de)雙(shuang)層(ceng)(ceng)(ceng)產生一(yi)(yi)個工(gong)(gong)作中層(ceng)(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)(ceng)中間(jian)(jian)(jian)有正中間(jian)(jian)(jian)膠(jiao)，因而同一(yi)(yi)工(gong)(gong)作中層(ceng)(ceng)(ceng)的(de)(de)雙(shuang)層(ceng)(ceng)(ceng)不銹(xiu)鋼絲(si)中間(jian)(jian)(jian)沒有交接點。因此 不容易在(zai)承(cheng)(cheng)擔氣(qi)體壓力時同于不銹(xiu)鋼絲(si)間(jian)(jian)(jian)的(de)(de)交叉式彎(wan)折而產生應力或磨(mo)擦(ca)磨(mo)壞。故使用性(xing)能(neng)好，能(neng)承(cheng)(cheng)擔髙(gao)壓。
３）高(gao)壓膠(jiao)管(guan)的外膠(jiao)層粘在提高(gao)層上起維護功效，一般選用氯(lv)丁膠(jiao)。應留(liu)意(yi)避免 其脆化開裂而危害全部(bu)橡膠(jiao)軟(ruan)管(guan)的使用壽(shou)命(ming)。
