１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)(ti)(ti)高(gao)(gao)層(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如(ru)(ru)圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即(ji)與液(ye)壓(ya)油觸碰(peng)，故(gu)規定在(zai)(zai)長期性(xing)(xing)運(yun)行狀態下(xia)不(bu)(bu)可(ke)受液(ye)體浸(jin)蝕，能(neng)補漏。在(zai)(zai)提(ti)(ti)(ti)高(gao)(gao)層(ceng)(ceng)(ceng)功效(xiao)下(xia)會承(cheng)擔(dan)一(yi)定工(gong)作壓(ya)力(li)。因(yin)而，宜選(xuan)用丁腈(jing)橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危害性(xing)(xing)能(neng)的(de)關(guan)鍵要(yao)素(su)也有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強度、薄厚和(he)永(yong)(yong)久性(xing)(xing)形(xing)變(bian)量。強度和(he)永(yong)(yong)久性(xing)(xing)形(xing)變(bian)量對密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)危害非常(chang)大。一(yi)般強度高(gao)(gao)、縮(suo)小后的(de)永(yong)(yong)久性(xing)(xing)形(xing)變(bian)量小，密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)則(ze)越(yue)好。一(yi)般是在(zai)(zai)７０～８５邵(shao)氏硬度，縮(suo)小永(yong)(yong)久性(xing)(xing)形(xing)變(bian)５０％時。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄厚建議是為１．５～２．５ｍｍ，太厚會在(zai)(zai)壓(ya)扣(kou)時提(ti)(ti)(ti)升其流(liu)動(dong)率，導致不(bu)(bu)必要(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭(tou)芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰(peng)內(nei)(nei)孔內(nei)(nei)沉積，減(jian)少商(shang)品流(liu)通(tong)橫截(jie)面(mian)；過(guo)薄會在(zai)(zai)壓(ya)扣(kou)時被壓(ya)裂。另外內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻稱性(xing)(xing)也很重要(yao)。假如(ru)(ru)薄厚不(bu)(bu)勻，縮(suo)小后會導致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)出現的(de)浮銹也是危害性(xing)(xing)能(neng)品質的(de)關(guan)鍵要(yao)素(su)。
２）高(gao)(gao)壓(ya)(ya)膠管關(guan)鍵借助(zhu)提高(gao)(gao)層(ceng)(ceng)來承受力(li)。手工(gong)編(bian)織橡膠軟管是靠膠漿(jiang)與(yu)內(nei)外黏膠粘緊，因(yin)為同一手工(gong)編(bian)織層(ceng)(ceng)內(nei)不(bu)銹鋼(gang)絲中(zhong)間(jian)的(de)(de)(de)互相觸碰，在承擔(dan)氣體壓(ya)(ya)力(li)的(de)(de)(de)時候(hou)會因(yin)分別伸縮式不(bu)一而(er)導致不(bu)銹鋼(gang)絲彼此(ci)之(zhi)間(jian)的(de)(de)(de)摩(mo)擦而(er)危害其使用性能。而(er)螺旋波紋(wen)管是由盤繞方位不(bu)一樣的(de)(de)(de)雙層(ceng)(ceng)產生(sheng)一個工(gong)作中(zhong)層(ceng)(ceng)，在雙層(ceng)(ceng)中(zhong)間(jian)有(you)正中(zhong)間(jian)膠，因(yin)而(er)同一工(gong)作中(zhong)層(ceng)(ceng)的(de)(de)(de)雙層(ceng)(ceng)不(bu)銹鋼(gang)絲中(zhong)間(jian)沒有(you)交接點。因(yin)此(ci) 不(bu)容易在承擔(dan)氣體壓(ya)(ya)力(li)時同于(yu)不(bu)銹鋼(gang)絲間(jian)的(de)(de)(de)交叉式彎折而(er)產生(sheng)應力(li)或磨(mo)(mo)擦磨(mo)(mo)壞。故使用性能好，能承擔(dan)髙壓(ya)(ya)。
３）高壓膠管(guan)的外膠層粘在提高層上起維護功效，一般選用氯丁(ding)膠。應留意避免(mian) 其脆化(hua)開裂而危害全(quan)部橡膠軟管(guan)的使用壽命。
