１、橡膠軟管總成
1）高壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)由(you)內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)和外膠(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖(tu)例），內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)立即(ji)與液(ye)壓(ya)(ya)油觸碰(peng)，故(gu)規定(ding)在長期性(xing)(xing)(xing)(xing)(xing)運(yun)行狀(zhuang)態(tai)下(xia)不可受液(ye)體浸蝕，能(neng)(neng)補漏。在提(ti)高層(ceng)(ceng)(ceng)功效(xiao)下(xia)會承(cheng)擔一(yi)定(ding)工作壓(ya)(ya)力。因而，宜選用丁腈(jing)橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外，危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)的(de)(de)關(guan)鍵要(yao)素也有內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)(de)強度(du)(du)、薄(bo)(bo)厚(hou)和永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)量(liang)。強度(du)(du)和永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)量(liang)對密封(feng)性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)危(wei)害(hai)非常大。一(yi)般強度(du)(du)高、縮(suo)小(xiao)后(hou)的(de)(de)永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)量(liang)小(xiao)，密封(feng)性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)則(ze)越好(hao)。一(yi)般是(shi)在７０～８５邵氏硬(ying)度(du)(du)，縮(suo)小(xiao)永(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)(bian)５０％時(shi)。內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)(bo)厚(hou)建議是(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)會在壓(ya)(ya)扣時(shi)提(ti)升其(qi)流(liu)(liu)動(dong)率，導(dao)致不必要(yao)的(de)(de)膠(jiao)(jiao)在接頭芯套與橡膠(jiao)(jiao)軟管(guan)(guan)的(de)(de)觸碰(peng)內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商品(pin)流(liu)(liu)通(tong)橫截面；過薄(bo)(bo)會在壓(ya)(ya)扣時(shi)被壓(ya)(ya)裂。另外內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)(xing)(xing)也很重(zhong)要(yao)。假(jia)如薄(bo)(bo)厚(hou)不勻，縮(suo)小(xiao)后(hou)會導(dao)致一(yi)面裂斷(duan)、一(yi)面堆膠(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)(de)浮銹也是(shi)危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)品(pin)質(zhi)的(de)(de)關(guan)鍵要(yao)素。
２）高壓膠管關鍵借助提高層(ceng)(ceng)(ceng)(ceng)來承(cheng)受力(li)。手工編織橡膠軟管是靠膠漿與內(nei)外黏膠粘緊，因(yin)為同(tong)(tong)一(yi)手工編織層(ceng)(ceng)(ceng)(ceng)內(nei)不銹(xiu)鋼(gang)絲(si)(si)中間(jian)的(de)(de)(de)互相(xiang)觸碰(peng)，在承(cheng)擔(dan)氣(qi)體壓力(li)的(de)(de)(de)時候(hou)會因(yin)分別伸(shen)縮式(shi)不一(yi)而導致不銹(xiu)鋼(gang)絲(si)(si)彼(bi)此(ci)之間(jian)的(de)(de)(de)摩(mo)擦而危害其使(shi)用性能(neng)。而螺(luo)旋(xuan)波紋管是由盤繞(rao)方位不一(yi)樣的(de)(de)(de)雙(shuang)層(ceng)(ceng)(ceng)(ceng)產(chan)生一(yi)個(ge)工作中層(ceng)(ceng)(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)(ceng)(ceng)中間(jian)有正中間(jian)膠，因(yin)而同(tong)(tong)一(yi)工作中層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)雙(shuang)層(ceng)(ceng)(ceng)(ceng)不銹(xiu)鋼(gang)絲(si)(si)中間(jian)沒(mei)有交(jiao)接點(dian)。因(yin)此(ci) 不容易在承(cheng)擔(dan)氣(qi)體壓力(li)時同(tong)(tong)于不銹(xiu)鋼(gang)絲(si)(si)間(jian)的(de)(de)(de)交(jiao)叉式(shi)彎折而產(chan)生應力(li)或磨(mo)擦磨(mo)壞。故使(shi)用性能(neng)好，能(neng)承(cheng)擔(dan)髙(gao)壓。
３）高壓膠管的外膠層粘在(zai)提高層上起維護功效，一般選(xuan)用氯丁(ding)膠。應留意(yi)避免 其脆化(hua)開(kai)裂而危害全部橡(xiang)膠軟管的使用壽命。
