１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)管(guan)由內膠(jiao)(jiao)(jiao)層(ceng)(ceng)、提高(gao)(gao)層(ceng)(ceng)和外(wai)(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如圖例），內膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液壓(ya)油(you)觸(chu)碰，故規定(ding)在長(chang)期性(xing)(xing)(xing)運行狀態下不可受(shou)液體浸蝕，能(neng)補漏。在提高(gao)(gao)層(ceng)(ceng)功效下會承擔一(yi)(yi)(yi)定(ding)工作(zuo)壓(ya)力。因而，宜選用丁腈橡(xiang)膠(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)粒(li)外(wai)(wai)，危(wei)(wei)害(hai)(hai)性(xing)(xing)(xing)能(neng)的(de)關鍵要(yao)素(su)(su)也有(you)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)強(qiang)度、薄厚(hou)(hou)和永(yong)久(jiu)性(xing)(xing)(xing)形變量(liang)。強(qiang)度和永(yong)久(jiu)性(xing)(xing)(xing)形變量(liang)對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危(wei)(wei)害(hai)(hai)非常大。一(yi)(yi)(yi)般強(qiang)度高(gao)(gao)、縮小(xiao)(xiao)(xiao)后(hou)的(de)永(yong)久(jiu)性(xing)(xing)(xing)形變量(liang)小(xiao)(xiao)(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好。一(yi)(yi)(yi)般是在７０～８５邵氏硬度，縮小(xiao)(xiao)(xiao)永(yong)久(jiu)性(xing)(xing)(xing)形變５０％時。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄厚(hou)(hou)建(jian)議是為(wei)１．５～２．５ｍｍ，太厚(hou)(hou)會在壓(ya)扣時提升其流動率，導致不必要(yao)的(de)膠(jiao)(jiao)(jiao)在接頭(tou)芯套與橡(xiang)膠(jiao)(jiao)(jiao)軟管(guan)的(de)觸(chu)碰內孔(kong)內沉積，減少商品流通橫截面；過薄會在壓(ya)扣時被壓(ya)裂。另外(wai)(wai)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)(hou)勻稱性(xing)(xing)(xing)也很(hen)重要(yao)。假如薄厚(hou)(hou)不勻，縮小(xiao)(xiao)(xiao)后(hou)會導致一(yi)(yi)(yi)面裂斷、一(yi)(yi)(yi)面堆膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)浮(fu)銹也是危(wei)(wei)害(hai)(hai)性(xing)(xing)(xing)能(neng)品質的(de)關鍵要(yao)素(su)(su)。
２）高壓(ya)膠(jiao)(jiao)管(guan)關鍵借(jie)助提高層(ceng)(ceng)來承受力。手(shou)工(gong)(gong)編織橡膠(jiao)(jiao)軟管(guan)是靠膠(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)粘(zhan)緊(jin)，因(yin)為(wei)同(tong)一(yi)手(shou)工(gong)(gong)編織層(ceng)(ceng)內(nei)不(bu)(bu)銹(xiu)鋼絲中間(jian)的(de)(de)互相觸碰，在(zai)(zai)承擔(dan)(dan)氣體壓(ya)力的(de)(de)時候會因(yin)分別伸縮式不(bu)(bu)一(yi)而(er)(er)導致不(bu)(bu)銹(xiu)鋼絲彼此之間(jian)的(de)(de)摩擦(ca)(ca)而(er)(er)危害(hai)其(qi)使(shi)用性能(neng)(neng)。而(er)(er)螺旋波紋管(guan)是由盤繞方(fang)位(wei)不(bu)(bu)一(yi)樣的(de)(de)雙層(ceng)(ceng)產(chan)生一(yi)個工(gong)(gong)作中層(ceng)(ceng)，在(zai)(zai)雙層(ceng)(ceng)中間(jian)有正中間(jian)膠(jiao)(jiao)，因(yin)而(er)(er)同(tong)一(yi)工(gong)(gong)作中層(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)不(bu)(bu)銹(xiu)鋼絲中間(jian)沒有交接點。因(yin)此 不(bu)(bu)容(rong)易在(zai)(zai)承擔(dan)(dan)氣體壓(ya)力時同(tong)于不(bu)(bu)銹(xiu)鋼絲間(jian)的(de)(de)交叉式彎折而(er)(er)產(chan)生應(ying)力或(huo)磨擦(ca)(ca)磨壞。故使(shi)用性能(neng)(neng)好，能(neng)(neng)承擔(dan)(dan)髙壓(ya)。
３）高壓膠(jiao)(jiao)(jiao)管(guan)的外膠(jiao)(jiao)(jiao)層(ceng)粘在提高層(ceng)上起維(wei)護功(gong)效，一(yi)般選用(yong)氯丁膠(jiao)(jiao)(jiao)。應留意避(bi)免(mian) 其脆化開裂而危害全部橡(xiang)膠(jiao)(jiao)(jiao)軟管(guan)的使用(yong)壽命(ming)。
