１、橡膠軟管總成
1）高壓(ya)膠(jiao)管(guan)由內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)、提(ti)(ti)高層(ceng)(ceng)(ceng)和(he)外(wai)膠(jiao)層(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)立(li)即與液壓(ya)油觸碰，故(gu)規定(ding)在長期性(xing)(xing)(xing)運行狀態下不(bu)可受液體浸蝕，能(neng)(neng)補(bu)漏。在提(ti)(ti)高層(ceng)(ceng)(ceng)功效下會承擔一(yi)(yi)定(ding)工作壓(ya)力。因而，宜選用丁腈橡膠(jiao)，除塑膠(jiao)粒外(wai)，危害性(xing)(xing)(xing)能(neng)(neng)的(de)(de)關鍵(jian)要(yao)素(su)(su)也(ye)有內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)的(de)(de)強(qiang)(qiang)度(du)、薄(bo)厚和(he)永久(jiu)(jiu)性(xing)(xing)(xing)形變量(liang)。強(qiang)(qiang)度(du)和(he)永久(jiu)(jiu)性(xing)(xing)(xing)形變量(liang)對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)危害非常大。一(yi)(yi)般(ban)強(qiang)(qiang)度(du)高、縮(suo)小后(hou)(hou)的(de)(de)永久(jiu)(jiu)性(xing)(xing)(xing)形變量(liang)小，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)則越好。一(yi)(yi)般(ban)是(shi)在７０～８５邵(shao)氏硬度(du)，縮(suo)小永久(jiu)(jiu)性(xing)(xing)(xing)形變５０％時。內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建議是(shi)為１．５～２．５ｍｍ，太厚會在壓(ya)扣(kou)時提(ti)(ti)升其流動(dong)率，導致(zhi)不(bu)必要(yao)的(de)(de)膠(jiao)在接頭芯(xin)套與橡膠(jiao)軟(ruan)管(guan)的(de)(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積，減少商品流通(tong)橫截面；過薄(bo)會在壓(ya)扣(kou)時被(bei)壓(ya)裂(lie)。另外(wai)內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)壁厚勻稱性(xing)(xing)(xing)也(ye)很重(zhong)要(yao)。假如薄(bo)厚不(bu)勻，縮(suo)小后(hou)(hou)會導致(zhi)一(yi)(yi)面裂(lie)斷、一(yi)(yi)面堆(dui)膠(jiao)。內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)(de)浮銹(xiu)也(ye)是(shi)危害性(xing)(xing)(xing)能(neng)(neng)品質的(de)(de)關鍵(jian)要(yao)素(su)(su)。
２）高壓(ya)膠(jiao)(jiao)管(guan)(guan)關鍵借(jie)助提高層(ceng)來承(cheng)(cheng)受力。手工(gong)編織橡膠(jiao)(jiao)軟管(guan)(guan)是(shi)靠(kao)膠(jiao)(jiao)漿(jiang)與內(nei)外黏膠(jiao)(jiao)粘緊，因為同(tong)一(yi)(yi)手工(gong)編織層(ceng)內(nei)不(bu)銹(xiu)鋼絲中(zhong)(zhong)間(jian)的(de)(de)互相(xiang)觸碰，在承(cheng)(cheng)擔(dan)(dan)氣體(ti)壓(ya)力的(de)(de)時候會因分(fen)別(bie)伸縮(suo)式(shi)(shi)不(bu)一(yi)(yi)而(er)(er)導致不(bu)銹(xiu)鋼絲彼此之間(jian)的(de)(de)摩擦(ca)而(er)(er)危害其使用(yong)性(xing)能。而(er)(er)螺(luo)旋波(bo)紋管(guan)(guan)是(shi)由盤繞(rao)方位不(bu)一(yi)(yi)樣的(de)(de)雙層(ceng)產生一(yi)(yi)個工(gong)作(zuo)中(zhong)(zhong)層(ceng)，在雙層(ceng)中(zhong)(zhong)間(jian)有正中(zhong)(zhong)間(jian)膠(jiao)(jiao)，因而(er)(er)同(tong)一(yi)(yi)工(gong)作(zuo)中(zhong)(zhong)層(ceng)的(de)(de)雙層(ceng)不(bu)銹(xiu)鋼絲中(zhong)(zhong)間(jian)沒有交接點。因此 不(bu)容易在承(cheng)(cheng)擔(dan)(dan)氣體(ti)壓(ya)力時同(tong)于不(bu)銹(xiu)鋼絲間(jian)的(de)(de)交叉式(shi)(shi)彎折(zhe)而(er)(er)產生應(ying)力或磨擦(ca)磨壞。故使用(yong)性(xing)能好，能承(cheng)(cheng)擔(dan)(dan)髙壓(ya)。
３）高(gao)壓(ya)膠(jiao)管(guan)的(de)外(wai)膠(jiao)層粘在提(ti)高(gao)層上起維(wei)護功效，一般選用氯(lv)丁膠(jiao)。應(ying)留意避免 其脆化開裂(lie)而危害全部橡(xiang)膠(jiao)軟管(guan)的(de)使用壽命。
