１、橡膠軟管總成
1）高(gao)壓膠(jiao)(jiao)(jiao)管由內(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與液(ye)(ye)壓油觸(chu)碰，故(gu)規定在(zai)(zai)長期性(xing)(xing)運(yun)行狀態下(xia)不可受液(ye)(ye)體浸蝕，能(neng)(neng)補(bu)漏。在(zai)(zai)提高(gao)層(ceng)(ceng)(ceng)功效下(xia)會承(cheng)擔一(yi)(yi)定工作壓力。因而，宜選(xuan)用丁腈橡膠(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)粒外，危(wei)害性(xing)(xing)能(neng)(neng)的(de)關鍵要(yao)素也有內(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強度、薄(bo)厚(hou)(hou)和(he)永久性(xing)(xing)形(xing)變(bian)(bian)量。強度和(he)永久性(xing)(xing)形(xing)變(bian)(bian)量對密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害非(fei)常大。一(yi)(yi)般(ban)強度高(gao)、縮(suo)小(xiao)后的(de)永久性(xing)(xing)形(xing)變(bian)(bian)量小(xiao)，密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好(hao)。一(yi)(yi)般(ban)是(shi)在(zai)(zai)７０～８５邵氏硬(ying)度，縮(suo)小(xiao)永久性(xing)(xing)形(xing)變(bian)(bian)５０％時(shi)。內(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚(hou)(hou)建(jian)議(yi)是(shi)為１．５～２．５ｍｍ，太厚(hou)(hou)會在(zai)(zai)壓扣時(shi)提升其流(liu)動率(lv)，導(dao)致(zhi)不必要(yao)的(de)膠(jiao)(jiao)(jiao)在(zai)(zai)接(jie)頭芯套與橡膠(jiao)(jiao)(jiao)軟管的(de)觸(chu)碰內(nei)(nei)(nei)(nei)孔內(nei)(nei)(nei)(nei)沉(chen)積，減(jian)少(shao)商(shang)品流(liu)通橫截面(mian)；過薄(bo)會在(zai)(zai)壓扣時(shi)被(bei)壓裂。另(ling)外內(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚(hou)(hou)勻(yun)稱性(xing)(xing)也很重要(yao)。假如薄(bo)厚(hou)(hou)不勻(yun)，縮(suo)小(xiao)后會導(dao)致(zhi)一(yi)(yi)面(mian)裂斷(duan)、一(yi)(yi)面(mian)堆膠(jiao)(jiao)(jiao)。內(nei)(nei)(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出(chu)現(xian)的(de)浮銹(xiu)也是(shi)危(wei)害性(xing)(xing)能(neng)(neng)品質的(de)關鍵要(yao)素。
２）高壓(ya)(ya)膠(jiao)管(guan)關鍵借(jie)助提(ti)高層(ceng)來承(cheng)受力(li)(li)。手工編(bian)織(zhi)橡膠(jiao)軟(ruan)管(guan)是靠膠(jiao)漿與內外黏膠(jiao)粘緊(jin)，因為同(tong)一(yi)手工編(bian)織(zhi)層(ceng)內不(bu)(bu)(bu)銹鋼絲(si)(si)中(zhong)間(jian)(jian)的(de)互相(xiang)觸(chu)碰(peng)，在承(cheng)擔氣(qi)體(ti)壓(ya)(ya)力(li)(li)的(de)時候會因分別伸縮(suo)式不(bu)(bu)(bu)一(yi)而導致不(bu)(bu)(bu)銹鋼絲(si)(si)彼此(ci)之間(jian)(jian)的(de)摩擦(ca)(ca)而危害其使用性(xing)能(neng)(neng)(neng)。而螺旋波紋(wen)管(guan)是由盤繞方位不(bu)(bu)(bu)一(yi)樣的(de)雙(shuang)層(ceng)產(chan)生一(yi)個(ge)工作中(zhong)層(ceng)，在雙(shuang)層(ceng)中(zhong)間(jian)(jian)有正中(zhong)間(jian)(jian)膠(jiao)，因而同(tong)一(yi)工作中(zhong)層(ceng)的(de)雙(shuang)層(ceng)不(bu)(bu)(bu)銹鋼絲(si)(si)中(zhong)間(jian)(jian)沒有交接點(dian)。因此(ci) 不(bu)(bu)(bu)容易在承(cheng)擔氣(qi)體(ti)壓(ya)(ya)力(li)(li)時同(tong)于不(bu)(bu)(bu)銹鋼絲(si)(si)間(jian)(jian)的(de)交叉式彎折而產(chan)生應力(li)(li)或磨擦(ca)(ca)磨壞。故使用性(xing)能(neng)(neng)(neng)好，能(neng)(neng)(neng)承(cheng)擔髙壓(ya)(ya)。
３）高壓膠(jiao)管的外膠(jiao)層粘在提高層上(shang)起維(wei)護(hu)功效，一般(ban)選用氯丁膠(jiao)。應留(liu)意避免 其(qi)脆化開裂(lie)而危害全部橡膠(jiao)軟管的使(shi)用壽命。
