１、橡膠軟管總成
1）高(gao)壓膠管(guan)由(you)內膠層(ceng)(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)(ceng)和外(wai)膠層(ceng)(ceng)(ceng)構(gou)成（如(ru)圖例），內膠層(ceng)(ceng)(ceng)立即與液(ye)壓油觸碰(peng)，故規定在長期(qi)性(xing)(xing)運行狀態下(xia)不(bu)可受液(ye)體浸蝕，能(neng)(neng)補漏。在提(ti)高(gao)層(ceng)(ceng)(ceng)功效下(xia)會承擔一(yi)定工作壓力。因而，宜選用丁腈(jing)橡膠，除塑(su)膠粒外(wai)，危害(hai)(hai)(hai)性(xing)(xing)能(neng)(neng)的(de)關鍵要素(su)也(ye)有內膠層(ceng)(ceng)(ceng)的(de)強度(du)、薄厚(hou)和永(yong)久(jiu)(jiu)性(xing)(xing)形變量(liang)。強度(du)和永(yong)久(jiu)(jiu)性(xing)(xing)形變量(liang)對密封性(xing)(xing)性(xing)(xing)能(neng)(neng)危害(hai)(hai)(hai)非常大。一(yi)般強度(du)高(gao)、縮小(xiao)(xiao)后的(de)永(yong)久(jiu)(jiu)性(xing)(xing)形變量(liang)小(xiao)(xiao)，密封性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好(hao)。一(yi)般是在７０～８５邵氏硬度(du)，縮小(xiao)(xiao)永(yong)久(jiu)(jiu)性(xing)(xing)形變５０％時(shi)。內膠層(ceng)(ceng)(ceng)薄厚(hou)建議(yi)是為１．５～２．５ｍｍ，太厚(hou)會在壓扣時(shi)提(ti)升其流(liu)動率，導(dao)致(zhi)不(bu)必(bi)要的(de)膠在接頭(tou)芯套與橡膠軟管(guan)的(de)觸碰(peng)內孔內沉積，減少(shao)商品流(liu)通橫截面(mian)；過(guo)薄會在壓扣時(shi)被(bei)壓裂(lie)。另外(wai)內膠層(ceng)(ceng)(ceng)壁厚(hou)勻(yun)稱性(xing)(xing)也(ye)很重要。假如(ru)薄厚(hou)不(bu)勻(yun)，縮小(xiao)(xiao)后會導(dao)致(zhi)一(yi)面(mian)裂(lie)斷、一(yi)面(mian)堆膠。內膠層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現(xian)的(de)浮銹也(ye)是危害(hai)(hai)(hai)性(xing)(xing)能(neng)(neng)品質的(de)關鍵要素(su)。
２）高(gao)壓(ya)膠(jiao)管關鍵借(jie)助提高(gao)層(ceng)(ceng)來(lai)承(cheng)受力(li)。手(shou)工(gong)(gong)編織(zhi)橡膠(jiao)軟管是(shi)靠膠(jiao)漿與內(nei)外黏膠(jiao)粘緊，因(yin)(yin)為同一(yi)(yi)手(shou)工(gong)(gong)編織(zhi)層(ceng)(ceng)內(nei)不銹(xiu)鋼(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)(jian)的(de)(de)互相觸碰(peng)，在(zai)(zai)承(cheng)擔氣體壓(ya)力(li)的(de)(de)時候(hou)會因(yin)(yin)分別伸縮(suo)式不一(yi)(yi)而(er)(er)導(dao)致不銹(xiu)鋼(gang)(gang)絲(si)彼此之間(jian)(jian)(jian)的(de)(de)摩擦(ca)而(er)(er)危害(hai)其使用(yong)性(xing)能。而(er)(er)螺旋波紋(wen)管是(shi)由(you)盤(pan)繞方位不一(yi)(yi)樣的(de)(de)雙(shuang)層(ceng)(ceng)產(chan)生一(yi)(yi)個工(gong)(gong)作(zuo)(zuo)中(zhong)(zhong)層(ceng)(ceng)，在(zai)(zai)雙(shuang)層(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)(jian)有正中(zhong)(zhong)間(jian)(jian)(jian)膠(jiao)，因(yin)(yin)而(er)(er)同一(yi)(yi)工(gong)(gong)作(zuo)(zuo)中(zhong)(zhong)層(ceng)(ceng)的(de)(de)雙(shuang)層(ceng)(ceng)不銹(xiu)鋼(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)(jian)沒有交(jiao)(jiao)接(jie)點。因(yin)(yin)此 不容易在(zai)(zai)承(cheng)擔氣體壓(ya)力(li)時同于不銹(xiu)鋼(gang)(gang)絲(si)間(jian)(jian)(jian)的(de)(de)交(jiao)(jiao)叉式彎折而(er)(er)產(chan)生應力(li)或磨(mo)擦(ca)磨(mo)壞。故使用(yong)性(xing)能好，能承(cheng)擔髙壓(ya)。
３）高壓膠管(guan)的外膠層(ceng)粘在提高層(ceng)上起(qi)維護(hu)功(gong)效，一般選用氯丁膠。應留意避免 其脆(cui)化(hua)開裂而(er)危害(hai)全部(bu)橡膠軟管(guan)的使(shi)用壽命。
