１、橡膠軟管總成
1）高壓膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)由內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高層(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如(ru)圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即(ji)與液壓油(you)觸碰(peng)，故規定在(zai)長期性(xing)(xing)運行(xing)狀態下(xia)不可(ke)受液體浸蝕，能(neng)(neng)補漏。在(zai)提(ti)高層(ceng)(ceng)功(gong)效下(xia)會承擔一定工作壓力。因而，宜(yi)選(xuan)用(yong)丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)(jiao)粒外(wai)，危(wei)害性(xing)(xing)能(neng)(neng)的(de)(de)關鍵(jian)要素(su)(su)也有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度、薄(bo)(bo)厚和永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)量。強(qiang)度和永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)量對密封(feng)性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害非常大。一般強(qiang)度高、縮小(xiao)(xiao)后的(de)(de)永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)量小(xiao)(xiao)，密封(feng)性(xing)(xing)性(xing)(xing)能(neng)(neng)則越(yue)好(hao)。一般是(shi)在(zai)７０～８５邵氏硬度，縮小(xiao)(xiao)永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)５０％時(shi)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)(bo)厚建議是(shi)為１．５～２．５ｍｍ，太厚會在(zai)壓扣(kou)時(shi)提(ti)升(sheng)其流(liu)動率，導致不必(bi)要的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟(ruan)管(guan)(guan)的(de)(de)觸碰(peng)內(nei)(nei)孔(kong)內(nei)(nei)沉積(ji)，減(jian)少(shao)商品流(liu)通橫截面；過薄(bo)(bo)會在(zai)壓扣(kou)時(shi)被壓裂。另(ling)外(wai)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁(bi)厚勻稱性(xing)(xing)也很重要。假(jia)如(ru)薄(bo)(bo)厚不勻，縮小(xiao)(xiao)后會導致一面裂斷、一面堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出(chu)現的(de)(de)浮(fu)銹也是(shi)危(wei)害性(xing)(xing)能(neng)(neng)品質(zhi)的(de)(de)關鍵(jian)要素(su)(su)。
２）高壓(ya)(ya)膠管關(guan)鍵借(jie)助提(ti)高層(ceng)來承受力(li)(li)。手(shou)工(gong)編織(zhi)橡膠軟管是(shi)靠膠漿與內外(wai)黏膠粘(zhan)緊，因為同(tong)一手(shou)工(gong)編織(zhi)層(ceng)內不(bu)(bu)(bu)(bu)銹鋼絲中(zhong)間(jian)(jian)的互相觸碰，在(zai)(zai)(zai)承擔(dan)氣體(ti)壓(ya)(ya)力(li)(li)的時候會(hui)因分(fen)別伸(shen)縮式(shi)(shi)不(bu)(bu)(bu)(bu)一而(er)導(dao)致(zhi)不(bu)(bu)(bu)(bu)銹鋼絲彼此(ci)(ci)之間(jian)(jian)的摩(mo)擦而(er)危(wei)害其使用性能。而(er)螺旋波(bo)紋管是(shi)由盤繞方(fang)位(wei)不(bu)(bu)(bu)(bu)一樣的雙層(ceng)產(chan)(chan)生(sheng)一個工(gong)作中(zhong)層(ceng)，在(zai)(zai)(zai)雙層(ceng)中(zhong)間(jian)(jian)有正(zheng)中(zhong)間(jian)(jian)膠，因而(er)同(tong)一工(gong)作中(zhong)層(ceng)的雙層(ceng)不(bu)(bu)(bu)(bu)銹鋼絲中(zhong)間(jian)(jian)沒有交接(jie)點。因此(ci)(ci) 不(bu)(bu)(bu)(bu)容易在(zai)(zai)(zai)承擔(dan)氣體(ti)壓(ya)(ya)力(li)(li)時同(tong)于不(bu)(bu)(bu)(bu)銹鋼絲間(jian)(jian)的交叉式(shi)(shi)彎折(zhe)而(er)產(chan)(chan)生(sheng)應力(li)(li)或磨擦磨壞。故使用性能好，能承擔(dan)髙壓(ya)(ya)。
３）高壓膠(jiao)(jiao)管(guan)(guan)的(de)外膠(jiao)(jiao)層(ceng)粘在提(ti)高層(ceng)上起維護功效，一般選用(yong)氯丁膠(jiao)(jiao)。應(ying)留(liu)意避免 其脆(cui)化開(kai)裂而危害全部橡膠(jiao)(jiao)軟管(guan)(guan)的(de)使(shi)用(yong)壽命。
