１、橡膠軟管總成
1）高壓(ya)(ya)(ya)膠管由內(nei)(nei)(nei)(nei)膠層(ceng)(ceng)、提(ti)高層(ceng)(ceng)和(he)外(wai)膠層(ceng)(ceng)構成(cheng)（如(ru)圖例），內(nei)(nei)(nei)(nei)膠層(ceng)(ceng)立即與液(ye)壓(ya)(ya)(ya)油(you)觸碰，故規定在(zai)長期性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)運行狀態(tai)下不(bu)可受液(ye)體浸(jin)蝕，能(neng)補漏。在(zai)提(ti)高層(ceng)(ceng)功效下會承擔一定工作壓(ya)(ya)(ya)力。因而，宜選(xuan)用丁腈橡膠，除塑膠粒外(wai)，危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)的(de)(de)關鍵要(yao)(yao)素也有內(nei)(nei)(nei)(nei)膠層(ceng)(ceng)的(de)(de)強度、薄厚(hou)(hou)和(he)永(yong)久性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量。強度和(he)永(yong)久性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量對(dui)密封性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)危(wei)害(hai)非常大。一般(ban)(ban)強度高、縮(suo)小后的(de)(de)永(yong)久性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量小，密封性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)則越好。一般(ban)(ban)是在(zai)７０～８５邵氏硬(ying)度，縮(suo)小永(yong)久性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)５０％時。內(nei)(nei)(nei)(nei)膠層(ceng)(ceng)薄厚(hou)(hou)建(jian)議(yi)是為１．５～２．５ｍｍ，太厚(hou)(hou)會在(zai)壓(ya)(ya)(ya)扣時提(ti)升(sheng)其流(liu)動率，導(dao)致不(bu)必要(yao)(yao)的(de)(de)膠在(zai)接(jie)頭芯套(tao)與橡膠軟管的(de)(de)觸碰內(nei)(nei)(nei)(nei)孔(kong)內(nei)(nei)(nei)(nei)沉積(ji)，減少商品流(liu)通(tong)橫(heng)截面；過薄會在(zai)壓(ya)(ya)(ya)扣時被壓(ya)(ya)(ya)裂(lie)。另外(wai)內(nei)(nei)(nei)(nei)膠層(ceng)(ceng)壁厚(hou)(hou)勻(yun)稱(cheng)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)也很重要(yao)(yao)。假如(ru)薄厚(hou)(hou)不(bu)勻(yun)，縮(suo)小后會導(dao)致一面裂(lie)斷、一面堆(dui)膠。內(nei)(nei)(nei)(nei)膠層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)浮(fu)銹(xiu)也是危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)品質的(de)(de)關鍵要(yao)(yao)素。
２）高(gao)壓膠(jiao)(jiao)管(guan)關鍵借助(zhu)提高(gao)層(ceng)(ceng)來承受力(li)。手工編織(zhi)橡膠(jiao)(jiao)軟(ruan)管(guan)是靠膠(jiao)(jiao)漿與內外(wai)黏膠(jiao)(jiao)粘緊，因為同(tong)一(yi)手工編織(zhi)層(ceng)(ceng)內不(bu)銹(xiu)鋼(gang)絲中間(jian)(jian)的(de)(de)互(hu)相觸碰，在承擔(dan)氣體(ti)壓力(li)的(de)(de)時候會因分別(bie)伸(shen)縮式(shi)不(bu)一(yi)而導致不(bu)銹(xiu)鋼(gang)絲彼此(ci)之間(jian)(jian)的(de)(de)摩擦而危害(hai)其使用(yong)性(xing)能(neng)。而螺(luo)旋波(bo)紋管(guan)是由(you)盤(pan)繞方(fang)位不(bu)一(yi)樣的(de)(de)雙層(ceng)(ceng)產(chan)生一(yi)個工作(zuo)中層(ceng)(ceng)，在雙層(ceng)(ceng)中間(jian)(jian)有正中間(jian)(jian)膠(jiao)(jiao)，因而同(tong)一(yi)工作(zuo)中層(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)不(bu)銹(xiu)鋼(gang)絲中間(jian)(jian)沒有交(jiao)接點。因此(ci) 不(bu)容易在承擔(dan)氣體(ti)壓力(li)時同(tong)于(yu)不(bu)銹(xiu)鋼(gang)絲間(jian)(jian)的(de)(de)交(jiao)叉(cha)式(shi)彎折而產(chan)生應(ying)力(li)或磨(mo)擦磨(mo)壞(huai)。故使用(yong)性(xing)能(neng)好，能(neng)承擔(dan)髙(gao)壓。
３）高(gao)壓膠管(guan)(guan)的外(wai)膠層粘在(zai)提高(gao)層上起維護功效，一般(ban)選用氯丁膠。應留(liu)意(yi)避(bi)免 其脆化開(kai)裂而危害全部橡(xiang)膠軟(ruan)管(guan)(guan)的使用壽命(ming)。
