１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)由內(nei)(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如圖(tu)例），內(nei)(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立(li)即與液壓(ya)(ya)油(you)觸碰(peng)，故規定(ding)在(zai)(zai)(zai)長期性(xing)(xing)(xing)(xing)運行狀態下(xia)(xia)不(bu)可(ke)受液體浸蝕，能(neng)(neng)補漏。在(zai)(zai)(zai)提(ti)高(gao)層(ceng)(ceng)功效下(xia)(xia)會(hui)承擔一定(ding)工作壓(ya)(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外(wai)，危(wei)(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)的(de)(de)(de)關(guan)鍵要素也(ye)有內(nei)(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)(de)強度(du)、薄(bo)厚和永久性(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)。強度(du)和永久性(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)對(dui)密封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)危(wei)(wei)害(hai)非常大。一般強度(du)高(gao)、縮小后的(de)(de)(de)永久性(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)小，密封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)則(ze)越好(hao)。一般是在(zai)(zai)(zai)７０～８５邵氏硬度(du)，縮小永久性(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)５０％時。內(nei)(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚建議是為１．５～２．５ｍｍ，太厚會(hui)在(zai)(zai)(zai)壓(ya)(ya)扣時提(ti)升(sheng)其流動率，導致不(bu)必要的(de)(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)(zai)接頭芯套(tao)與橡膠(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)(de)觸碰(peng)內(nei)(nei)(nei)(nei)(nei)孔內(nei)(nei)(nei)(nei)(nei)沉積，減少(shao)商品流通橫(heng)截面；過薄(bo)會(hui)在(zai)(zai)(zai)壓(ya)(ya)扣時被壓(ya)(ya)裂(lie)。另外(wai)內(nei)(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚勻稱(cheng)性(xing)(xing)(xing)(xing)也(ye)很重(zhong)要。假如薄(bo)厚不(bu)勻，縮小后會(hui)導致一面裂(lie)斷、一面堆(dui)膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)(de)浮銹也(ye)是危(wei)(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)品質的(de)(de)(de)關(guan)鍵要素。
２）高壓膠(jiao)管(guan)關(guan)鍵借助提(ti)高層(ceng)來(lai)承受(shou)力(li)。手工(gong)(gong)編(bian)織橡(xiang)膠(jiao)軟管(guan)是(shi)靠(kao)膠(jiao)漿(jiang)與內(nei)外黏膠(jiao)粘緊，因(yin)(yin)為同(tong)一(yi)手工(gong)(gong)編(bian)織層(ceng)內(nei)不(bu)銹(xiu)(xiu)(xiu)鋼絲(si)(si)(si)中(zhong)(zhong)間(jian)(jian)的(de)互相觸碰(peng)，在承擔氣體(ti)壓力(li)的(de)時候會因(yin)(yin)分別伸縮式不(bu)一(yi)而導致(zhi)不(bu)銹(xiu)(xiu)(xiu)鋼絲(si)(si)(si)彼此(ci)之間(jian)(jian)的(de)摩擦(ca)而危害其使(shi)用(yong)性能。而螺旋波紋管(guan)是(shi)由盤(pan)繞方位不(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(jian)(jian)有正(zheng)中(zhong)(zhong)間(jian)(jian)膠(jiao)，因(yin)(yin)而同(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)層(ceng)的(de)雙(shuang)層(ceng)不(bu)銹(xiu)(xiu)(xiu)鋼絲(si)(si)(si)中(zhong)(zhong)間(jian)(jian)沒有交接點(dian)。因(yin)(yin)此(ci) 不(bu)容易在承擔氣體(ti)壓力(li)時同(tong)于不(bu)銹(xiu)(xiu)(xiu)鋼絲(si)(si)(si)間(jian)(jian)的(de)交叉式彎折而產生應力(li)或磨(mo)擦(ca)磨(mo)壞。故使(shi)用(yong)性能好，能承擔髙壓。
３）高壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層粘在提(ti)高層上起維(wei)護功效，一般(ban)選用氯丁膠(jiao)(jiao)。應留意避(bi)免 其脆化(hua)開裂而危害全部橡膠(jiao)(jiao)軟管的使用壽(shou)命。
