１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)管由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)(ti)高層(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構(gou)成（如圖例），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與液壓(ya)油(you)觸碰，故(gu)規定在(zai)長(chang)期(qi)性(xing)(xing)(xing)(xing)運行狀態下(xia)不可受(shou)液體浸蝕，能(neng)補漏(lou)。在(zai)提(ti)(ti)高層(ceng)(ceng)(ceng)功效下(xia)會(hui)承擔一(yi)(yi)定工作壓(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)粒外，危害(hai)性(xing)(xing)(xing)(xing)能(neng)的(de)(de)關(guan)(guan)鍵要(yao)素(su)也有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)(de)強度、薄(bo)厚(hou)(hou)(hou)和(he)永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)量(liang)(liang)。強度和(he)永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)量(liang)(liang)對密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)危害(hai)非常大。一(yi)(yi)般(ban)強度高、縮(suo)小(xiao)后的(de)(de)永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)量(liang)(liang)小(xiao)，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)則越(yue)好。一(yi)(yi)般(ban)是(shi)在(zai)７０～８５邵氏硬度，縮(suo)小(xiao)永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)５０％時。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚(hou)(hou)(hou)建議是(shi)為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會(hui)在(zai)壓(ya)扣(kou)時提(ti)(ti)升其流動率，導(dao)致(zhi)不必(bi)要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)接(jie)頭芯(xin)套與橡膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)觸碰內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積(ji)，減少商品(pin)流通橫(heng)截面；過薄(bo)會(hui)在(zai)壓(ya)扣(kou)時被壓(ya)裂。另外內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚(hou)(hou)(hou)勻稱(cheng)性(xing)(xing)(xing)(xing)也很(hen)重要(yao)。假(jia)如薄(bo)厚(hou)(hou)(hou)不勻，縮(suo)小(xiao)后會(hui)導(dao)致(zhi)一(yi)(yi)面裂斷、一(yi)(yi)面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)(de)浮銹(xiu)也是(shi)危害(hai)性(xing)(xing)(xing)(xing)能(neng)品(pin)質(zhi)的(de)(de)關(guan)(guan)鍵要(yao)素(su)。
２）高(gao)壓膠(jiao)(jiao)管關鍵借(jie)助提高(gao)層(ceng)(ceng)來承(cheng)受力(li)(li)。手工(gong)編織橡膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿(jiang)與內外(wai)黏膠(jiao)(jiao)粘緊，因為(wei)同一(yi)(yi)(yi)手工(gong)編織層(ceng)(ceng)內不(bu)(bu)(bu)(bu)銹鋼絲(si)(si)中(zhong)間(jian)(jian)的互相觸碰，在承(cheng)擔(dan)氣(qi)體壓力(li)(li)的時候會因分別伸縮式(shi)不(bu)(bu)(bu)(bu)一(yi)(yi)(yi)而導致(zhi)不(bu)(bu)(bu)(bu)銹鋼絲(si)(si)彼(bi)此之間(jian)(jian)的摩擦而危害(hai)其使用(yong)性(xing)能(neng)。而螺旋波紋管是由盤繞方位(wei)不(bu)(bu)(bu)(bu)一(yi)(yi)(yi)樣的雙層(ceng)(ceng)產(chan)生(sheng)一(yi)(yi)(yi)個工(gong)作(zuo)中(zhong)層(ceng)(ceng)，在雙層(ceng)(ceng)中(zhong)間(jian)(jian)有(you)正中(zhong)間(jian)(jian)膠(jiao)(jiao)，因而同一(yi)(yi)(yi)工(gong)作(zuo)中(zhong)層(ceng)(ceng)的雙層(ceng)(ceng)不(bu)(bu)(bu)(bu)銹鋼絲(si)(si)中(zhong)間(jian)(jian)沒有(you)交接點。因此 不(bu)(bu)(bu)(bu)容(rong)易在承(cheng)擔(dan)氣(qi)體壓力(li)(li)時同于不(bu)(bu)(bu)(bu)銹鋼絲(si)(si)間(jian)(jian)的交叉式(shi)彎(wan)折而產(chan)生(sheng)應力(li)(li)或(huo)磨擦磨壞(huai)。故使用(yong)性(xing)能(neng)好，能(neng)承(cheng)擔(dan)髙壓。
３）高壓膠(jiao)管的(de)外膠(jiao)層(ceng)粘在提高層(ceng)上起維護功效，一般(ban)選用(yong)氯丁(ding)膠(jiao)。應留意(yi)避(bi)免 其脆(cui)化開裂而危害全(quan)部橡膠(jiao)軟管的(de)使用(yong)壽命。
