１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)管由內膠(jiao)(jiao)層(ceng)(ceng)、提高(gao)層(ceng)(ceng)和外膠(jiao)(jiao)層(ceng)(ceng)構(gou)成（如(ru)圖例），內膠(jiao)(jiao)層(ceng)(ceng)立即與(yu)液壓(ya)油觸碰(peng)，故規定在(zai)長期性(xing)(xing)(xing)(xing)(xing)運(yun)行狀(zhuang)態下不(bu)可受(shou)液體浸蝕，能(neng)補漏。在(zai)提高(gao)層(ceng)(ceng)功效下會(hui)(hui)承擔一定工作壓(ya)力。因而，宜選用丁(ding)腈橡膠(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)粒外，危(wei)害性(xing)(xing)(xing)(xing)(xing)能(neng)的(de)關鍵要素(su)也有內膠(jiao)(jiao)層(ceng)(ceng)的(de)強度、薄厚和永久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)。強度和永久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)對密(mi)封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)危(wei)害非常大。一般強度高(gao)、縮小(xiao)(xiao)后的(de)永久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)小(xiao)(xiao)，密(mi)封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)則越好。一般是(shi)(shi)(shi)在(zai)７０～８５邵氏硬度，縮小(xiao)(xiao)永久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)５０％時。內膠(jiao)(jiao)層(ceng)(ceng)薄厚建議(yi)是(shi)(shi)(shi)為(wei)１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)壓(ya)扣時提升其流(liu)動率，導(dao)致不(bu)必要的(de)膠(jiao)(jiao)在(zai)接頭芯套與(yu)橡膠(jiao)(jiao)軟管的(de)觸碰(peng)內孔內沉(chen)積，減少商(shang)品(pin)流(liu)通(tong)橫截面(mian)(mian)；過薄會(hui)(hui)在(zai)壓(ya)扣時被壓(ya)裂。另(ling)外內膠(jiao)(jiao)層(ceng)(ceng)壁厚勻稱性(xing)(xing)(xing)(xing)(xing)也很重要。假(jia)如(ru)薄厚不(bu)勻，縮小(xiao)(xiao)后會(hui)(hui)導(dao)致一面(mian)(mian)裂斷(duan)、一面(mian)(mian)堆膠(jiao)(jiao)。內膠(jiao)(jiao)層(ceng)(ceng)表(biao)層(ceng)(ceng)出現的(de)浮銹(xiu)也是(shi)(shi)(shi)危(wei)害性(xing)(xing)(xing)(xing)(xing)能(neng)品(pin)質的(de)關鍵要素(su)。
２）高壓(ya)膠(jiao)管(guan)(guan)關(guan)鍵借助提(ti)高層(ceng)(ceng)來承受力。手工(gong)(gong)編(bian)織橡膠(jiao)軟管(guan)(guan)是靠膠(jiao)漿與(yu)內外黏(nian)膠(jiao)粘緊，因為同一手工(gong)(gong)編(bian)織層(ceng)(ceng)內不銹(xiu)(xiu)鋼(gang)絲(si)中(zhong)(zhong)間的互相觸碰(peng)，在承擔氣體壓(ya)力的時候會因分別伸縮(suo)式不一而(er)導致不銹(xiu)(xiu)鋼(gang)絲(si)彼此(ci)之間的摩擦(ca)而(er)危害其使(shi)用(yong)(yong)性(xing)(xing)能。而(er)螺旋波紋管(guan)(guan)是由盤繞方位不一樣的雙(shuang)層(ceng)(ceng)產生一個工(gong)(gong)作中(zhong)(zhong)層(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)中(zhong)(zhong)間有正中(zhong)(zhong)間膠(jiao)，因而(er)同一工(gong)(gong)作中(zhong)(zhong)層(ceng)(ceng)的雙(shuang)層(ceng)(ceng)不銹(xiu)(xiu)鋼(gang)絲(si)中(zhong)(zhong)間沒有交接點。因此(ci) 不容(rong)易在承擔氣體壓(ya)力時同于不銹(xiu)(xiu)鋼(gang)絲(si)間的交叉(cha)式彎折而(er)產生應力或磨(mo)擦(ca)磨(mo)壞。故使(shi)用(yong)(yong)性(xing)(xing)能好，能承擔髙壓(ya)。
３）高壓膠管(guan)的(de)(de)外膠層(ceng)粘在提高層(ceng)上起維護功(gong)效，一般選(xuan)用氯丁膠。應留意避免 其脆化(hua)開裂而危害全部橡膠軟管(guan)的(de)(de)使用壽命。
