１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)由內膠(jiao)(jiao)(jiao)(jiao)層(ceng)、提(ti)(ti)高(gao)層(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)構成（如(ru)圖例），內膠(jiao)(jiao)(jiao)(jiao)層(ceng)立即與液(ye)壓(ya)油觸碰，故規定在(zai)(zai)長期性(xing)(xing)(xing)(xing)運行狀態下(xia)不(bu)可(ke)受(shou)液(ye)體(ti)浸蝕，能(neng)補漏。在(zai)(zai)提(ti)(ti)高(gao)層(ceng)功效下(xia)會(hui)(hui)承擔一(yi)定工作壓(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危(wei)(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)的(de)關(guan)鍵(jian)要(yao)素也(ye)有內膠(jiao)(jiao)(jiao)(jiao)層(ceng)的(de)強(qiang)度、薄(bo)厚(hou)和(he)永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量。強(qiang)度和(he)永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量對密(mi)封(feng)(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)危(wei)(wei)害(hai)非常(chang)大。一(yi)般強(qiang)度高(gao)、縮小后(hou)(hou)的(de)永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量小，密(mi)封(feng)(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)則越好。一(yi)般是(shi)在(zai)(zai)７０～８５邵氏硬度，縮小永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時(shi)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)薄(bo)厚(hou)建議是(shi)為１．５～２．５ｍｍ，太厚(hou)會(hui)(hui)在(zai)(zai)壓(ya)扣時(shi)提(ti)(ti)升(sheng)其流動(dong)率，導(dao)致不(bu)必要(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟(ruan)管(guan)(guan)的(de)觸碰內孔內沉積，減少商品流通(tong)橫截面(mian)；過薄(bo)會(hui)(hui)在(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂。另外內膠(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)(xing)也(ye)很重要(yao)。假如(ru)薄(bo)厚(hou)不(bu)勻，縮小后(hou)(hou)會(hui)(hui)導(dao)致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)表(biao)層(ceng)出現(xian)的(de)浮銹也(ye)是(shi)危(wei)(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)品質的(de)關(guan)鍵(jian)要(yao)素。
２）高壓膠(jiao)管關鍵(jian)借助提高層(ceng)來承(cheng)受力(li)。手工(gong)(gong)編(bian)織(zhi)(zhi)橡膠(jiao)軟管是(shi)靠膠(jiao)漿與內外黏膠(jiao)粘緊，因(yin)為同(tong)一(yi)手工(gong)(gong)編(bian)織(zhi)(zhi)層(ceng)內不(bu)(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間的(de)互相觸碰(peng)，在承(cheng)擔(dan)氣體(ti)壓力(li)的(de)時(shi)候會因(yin)分別伸縮(suo)式不(bu)(bu)一(yi)而導致(zhi)不(bu)(bu)銹鋼(gang)絲(si)彼此之間的(de)摩擦(ca)而危害(hai)其使(shi)用(yong)性能。而螺旋波紋(wen)管是(shi)由(you)盤繞(rao)方(fang)位不(bu)(bu)一(yi)樣的(de)雙(shuang)層(ceng)產生一(yi)個工(gong)(gong)作中(zhong)(zhong)層(ceng)，在雙(shuang)層(ceng)中(zhong)(zhong)間有正中(zhong)(zhong)間膠(jiao)，因(yin)而同(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)層(ceng)的(de)雙(shuang)層(ceng)不(bu)(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間沒有交(jiao)接點。因(yin)此 不(bu)(bu)容易在承(cheng)擔(dan)氣體(ti)壓力(li)時(shi)同(tong)于(yu)不(bu)(bu)銹鋼(gang)絲(si)間的(de)交(jiao)叉式彎折而產生應(ying)力(li)或磨擦(ca)磨壞(huai)。故使(shi)用(yong)性能好，能承(cheng)擔(dan)髙壓。
３）高壓(ya)膠(jiao)管(guan)的(de)(de)外膠(jiao)層(ceng)粘在提高層(ceng)上起維護功效(xiao)，一(yi)般選用(yong)氯丁膠(jiao)。應留意避免(mian) 其(qi)脆化開裂而危害全部橡膠(jiao)軟管(guan)的(de)(de)使用(yong)壽(shou)命。
