１、橡膠軟管總成
1）高壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)由內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層、提高層和(he)外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)層構成(cheng)（如圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層立(li)即與液壓(ya)(ya)油(you)觸碰，故(gu)規定在長期性(xing)(xing)(xing)(xing)(xing)運行狀態下不(bu)可受液體浸(jin)蝕(shi)，能補(bu)漏(lou)。在提高層功效(xiao)下會承擔一(yi)(yi)定工作壓(ya)(ya)力(li)。因而，宜選用(yong)丁(ding)腈(jing)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)(jiao)粒外(wai)(wai)，危害性(xing)(xing)(xing)(xing)(xing)能的(de)(de)關鍵(jian)要素也(ye)有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層的(de)(de)強度、薄(bo)厚(hou)(hou)和(he)永久性(xing)(xing)(xing)(xing)(xing)形變量(liang)。強度和(he)永久性(xing)(xing)(xing)(xing)(xing)形變量(liang)對密(mi)封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能危害非常(chang)大。一(yi)(yi)般(ban)強度高、縮(suo)小后的(de)(de)永久性(xing)(xing)(xing)(xing)(xing)形變量(liang)小，密(mi)封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能則越好(hao)。一(yi)(yi)般(ban)是在７０～８５邵氏硬(ying)度，縮(suo)小永久性(xing)(xing)(xing)(xing)(xing)形變５０％時(shi)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層薄(bo)厚(hou)(hou)建(jian)議是為１．５～２．５ｍｍ，太厚(hou)(hou)會在壓(ya)(ya)扣時(shi)提升其流(liu)動(dong)率，導(dao)致不(bu)必(bi)要的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在接頭(tou)芯套與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟(ruan)管(guan)的(de)(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積，減少(shao)商品流(liu)通橫截面；過薄(bo)會在壓(ya)(ya)扣時(shi)被壓(ya)(ya)裂(lie)(lie)。另外(wai)(wai)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層壁厚(hou)(hou)勻稱性(xing)(xing)(xing)(xing)(xing)也(ye)很重要。假如薄(bo)厚(hou)(hou)不(bu)勻，縮(suo)小后會導(dao)致一(yi)(yi)面裂(lie)(lie)斷、一(yi)(yi)面堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層表層出現(xian)的(de)(de)浮(fu)銹(xiu)也(ye)是危害性(xing)(xing)(xing)(xing)(xing)能品質的(de)(de)關鍵(jian)要素。
２）高壓(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)關鍵借助提高層(ceng)(ceng)(ceng)來承(cheng)受力(li)。手工(gong)編織(zhi)(zhi)橡膠(jiao)(jiao)(jiao)軟管(guan)是靠膠(jiao)(jiao)(jiao)漿(jiang)與內外黏膠(jiao)(jiao)(jiao)粘(zhan)緊，因為(wei)同一(yi)(yi)(yi)(yi)手工(gong)編織(zhi)(zhi)層(ceng)(ceng)(ceng)內不(bu)(bu)銹鋼絲中(zhong)(zhong)間(jian)的(de)互相觸碰，在承(cheng)擔氣體壓(ya)(ya)力(li)的(de)時(shi)候(hou)會因分(fen)別伸(shen)縮式不(bu)(bu)一(yi)(yi)(yi)(yi)而導致不(bu)(bu)銹鋼絲彼此(ci)之間(jian)的(de)摩擦而危害其使用性能。而螺(luo)旋波紋管(guan)是由盤繞方(fang)位不(bu)(bu)一(yi)(yi)(yi)(yi)樣的(de)雙層(ceng)(ceng)(ceng)產(chan)生一(yi)(yi)(yi)(yi)個(ge)工(gong)作(zuo)(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)中(zhong)(zhong)間(jian)有(you)正中(zhong)(zhong)間(jian)膠(jiao)(jiao)(jiao)，因而同一(yi)(yi)(yi)(yi)工(gong)作(zuo)(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)的(de)雙層(ceng)(ceng)(ceng)不(bu)(bu)銹鋼絲中(zhong)(zhong)間(jian)沒有(you)交接點。因此(ci) 不(bu)(bu)容易在承(cheng)擔氣體壓(ya)(ya)力(li)時(shi)同于不(bu)(bu)銹鋼絲間(jian)的(de)交叉式彎折而產(chan)生應力(li)或磨(mo)擦磨(mo)壞。故使用性能好，能承(cheng)擔髙壓(ya)(ya)。
３）高壓(ya)膠管的外(wai)膠層粘在提(ti)高層上(shang)起(qi)維護(hu)功效(xiao)，一般選用氯丁膠。應留意避免 其脆化(hua)開裂而(er)危害全部橡膠軟管的使用壽命。
