１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)層(ceng)(ceng)、提高(gao)(gao)層(ceng)(ceng)和(he)外(wai)(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)構(gou)成(cheng)（如圖例），內膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即(ji)與(yu)液壓(ya)油觸碰，故規定在(zai)(zai)長(chang)期性(xing)運行狀態下(xia)不可受液體浸蝕(shi)，能(neng)補漏(lou)。在(zai)(zai)提高(gao)(gao)層(ceng)(ceng)功(gong)效下(xia)會承擔(dan)一定工作壓(ya)力。因而(er)，宜選用丁腈(jing)橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外(wai)(wai)，危(wei)害(hai)(hai)性(xing)能(neng)的(de)關鍵(jian)(jian)要(yao)素也(ye)(ye)有(you)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)強度(du)、薄(bo)(bo)厚(hou)和(he)永久性(xing)形(xing)(xing)變量。強度(du)和(he)永久性(xing)形(xing)(xing)變量對密封性(xing)性(xing)能(neng)危(wei)害(hai)(hai)非常大。一般強度(du)高(gao)(gao)、縮小后(hou)(hou)的(de)永久性(xing)形(xing)(xing)變量小，密封性(xing)性(xing)能(neng)則越好。一般是(shi)在(zai)(zai)７０～８５邵(shao)氏硬度(du)，縮小永久性(xing)形(xing)(xing)變５０％時(shi)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)(bo)厚(hou)建議是(shi)為１．５～２．５ｍｍ，太厚(hou)會在(zai)(zai)壓(ya)扣(kou)時(shi)提升其(qi)流動(dong)率，導(dao)致不必要(yao)的(de)膠(jiao)(jiao)(jiao)在(zai)(zai)接頭(tou)芯套與(yu)橡膠(jiao)(jiao)(jiao)軟(ruan)管的(de)觸碰內孔內沉(chen)積，減少(shao)商品流通(tong)橫截面；過薄(bo)(bo)會在(zai)(zai)壓(ya)扣(kou)時(shi)被壓(ya)裂。另外(wai)(wai)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱(cheng)性(xing)也(ye)(ye)很重要(yao)。假如薄(bo)(bo)厚(hou)不勻，縮小后(hou)(hou)會導(dao)致一面裂斷、一面堆膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)浮銹也(ye)(ye)是(shi)危(wei)害(hai)(hai)性(xing)能(neng)品質(zhi)的(de)關鍵(jian)(jian)要(yao)素。
２）高壓膠(jiao)管(guan)關鍵借助提高層(ceng)(ceng)來承(cheng)受(shou)力。手(shou)(shou)工(gong)編(bian)織橡(xiang)膠(jiao)軟管(guan)是(shi)(shi)靠膠(jiao)漿與內外黏膠(jiao)粘(zhan)緊(jin)，因(yin)為同(tong)一(yi)手(shou)(shou)工(gong)編(bian)織層(ceng)(ceng)內不(bu)(bu)銹鋼絲(si)中(zhong)(zhong)間的(de)(de)(de)(de)互相(xiang)觸碰(peng)，在(zai)承(cheng)擔氣體(ti)壓力的(de)(de)(de)(de)時候會因(yin)分別伸(shen)縮式不(bu)(bu)一(yi)而(er)導致不(bu)(bu)銹鋼絲(si)彼此之間的(de)(de)(de)(de)摩擦(ca)而(er)危害(hai)其使(shi)(shi)用性(xing)能。而(er)螺旋(xuan)波紋管(guan)是(shi)(shi)由盤(pan)繞方(fang)位不(bu)(bu)一(yi)樣(yang)的(de)(de)(de)(de)雙層(ceng)(ceng)產(chan)(chan)生一(yi)個(ge)工(gong)作中(zhong)(zhong)層(ceng)(ceng)，在(zai)雙層(ceng)(ceng)中(zhong)(zhong)間有正(zheng)中(zhong)(zhong)間膠(jiao)，因(yin)而(er)同(tong)一(yi)工(gong)作中(zhong)(zhong)層(ceng)(ceng)的(de)(de)(de)(de)雙層(ceng)(ceng)不(bu)(bu)銹鋼絲(si)中(zhong)(zhong)間沒有交接點。因(yin)此 不(bu)(bu)容易在(zai)承(cheng)擔氣體(ti)壓力時同(tong)于不(bu)(bu)銹鋼絲(si)間的(de)(de)(de)(de)交叉式彎折(zhe)而(er)產(chan)(chan)生應力或磨擦(ca)磨壞。故使(shi)(shi)用性(xing)能好，能承(cheng)擔髙壓。
３）高壓膠(jiao)(jiao)管的(de)外膠(jiao)(jiao)層粘在提高層上起維護功效，一(yi)般選用(yong)氯丁膠(jiao)(jiao)。應(ying)留意避免 其脆化(hua)開(kai)裂而危害全部橡膠(jiao)(jiao)軟管的(de)使用(yong)壽(shou)命(ming)。
