１、橡膠軟管總成
1）高(gao)壓(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管由(you)內膠(jiao)(jiao)(jiao)層、提(ti)(ti)高(gao)層和(he)外膠(jiao)(jiao)(jiao)層構成（如圖例），內膠(jiao)(jiao)(jiao)層立即與液(ye)壓(ya)(ya)(ya)油觸(chu)碰，故規(gui)定在長(chang)期性(xing)(xing)(xing)(xing)運行狀態下(xia)不(bu)(bu)可受液(ye)體浸蝕，能補漏。在提(ti)(ti)高(gao)層功效下(xia)會承(cheng)擔一(yi)(yi)定工作(zuo)壓(ya)(ya)(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)(jiao)粒外，危(wei)害(hai)性(xing)(xing)(xing)(xing)能的(de)(de)關鍵要(yao)(yao)素也有內膠(jiao)(jiao)(jiao)層的(de)(de)強度、薄厚(hou)(hou)(hou)和(he)永久性(xing)(xing)(xing)(xing)形(xing)變量(liang)。強度和(he)永久性(xing)(xing)(xing)(xing)形(xing)變量(liang)對(dui)密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能危(wei)害(hai)非常大(da)。一(yi)(yi)般強度高(gao)、縮小后的(de)(de)永久性(xing)(xing)(xing)(xing)形(xing)變量(liang)小，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能則(ze)越好(hao)。一(yi)(yi)般是在７０～８５邵氏硬度，縮小永久性(xing)(xing)(xing)(xing)形(xing)變５０％時。內膠(jiao)(jiao)(jiao)層薄厚(hou)(hou)(hou)建(jian)議是為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會在壓(ya)(ya)(ya)扣(kou)(kou)時提(ti)(ti)升其流動率(lv)，導(dao)致不(bu)(bu)必(bi)要(yao)(yao)的(de)(de)膠(jiao)(jiao)(jiao)在接頭芯套(tao)與橡膠(jiao)(jiao)(jiao)軟(ruan)管的(de)(de)觸(chu)碰內孔內沉積(ji)，減少商品(pin)流通(tong)橫截面；過(guo)薄會在壓(ya)(ya)(ya)扣(kou)(kou)時被壓(ya)(ya)(ya)裂(lie)。另外內膠(jiao)(jiao)(jiao)層壁厚(hou)(hou)(hou)勻稱性(xing)(xing)(xing)(xing)也很重要(yao)(yao)。假如薄厚(hou)(hou)(hou)不(bu)(bu)勻，縮小后會導(dao)致一(yi)(yi)面裂(lie)斷、一(yi)(yi)面堆膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層表層出現的(de)(de)浮銹也是危(wei)害(hai)性(xing)(xing)(xing)(xing)能品(pin)質的(de)(de)關鍵要(yao)(yao)素。
２）高(gao)壓(ya)(ya)膠(jiao)(jiao)管(guan)(guan)關鍵借助提(ti)高(gao)層來承(cheng)受力。手工(gong)(gong)(gong)編織橡膠(jiao)(jiao)軟管(guan)(guan)是(shi)靠膠(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)粘(zhan)緊，因(yin)(yin)為同(tong)一(yi)(yi)(yi)手工(gong)(gong)(gong)編織層內(nei)不(bu)(bu)(bu)銹(xiu)(xiu)鋼絲(si)中間(jian)的(de)(de)互相觸碰，在(zai)承(cheng)擔氣體壓(ya)(ya)力的(de)(de)時(shi)候會(hui)因(yin)(yin)分別(bie)伸(shen)縮式(shi)不(bu)(bu)(bu)一(yi)(yi)(yi)而(er)導致不(bu)(bu)(bu)銹(xiu)(xiu)鋼絲(si)彼此之(zhi)間(jian)的(de)(de)摩擦(ca)(ca)而(er)危害其使用性能(neng)。而(er)螺旋波(bo)紋管(guan)(guan)是(shi)由(you)盤繞(rao)方(fang)位不(bu)(bu)(bu)一(yi)(yi)(yi)樣的(de)(de)雙層產(chan)(chan)生一(yi)(yi)(yi)個工(gong)(gong)(gong)作中層，在(zai)雙層中間(jian)有正中間(jian)膠(jiao)(jiao)，因(yin)(yin)而(er)同(tong)一(yi)(yi)(yi)工(gong)(gong)(gong)作中層的(de)(de)雙層不(bu)(bu)(bu)銹(xiu)(xiu)鋼絲(si)中間(jian)沒有交接點。因(yin)(yin)此 不(bu)(bu)(bu)容易在(zai)承(cheng)擔氣體壓(ya)(ya)力時(shi)同(tong)于不(bu)(bu)(bu)銹(xiu)(xiu)鋼絲(si)間(jian)的(de)(de)交叉式(shi)彎折而(er)產(chan)(chan)生應力或磨擦(ca)(ca)磨壞。故使用性能(neng)好，能(neng)承(cheng)擔髙壓(ya)(ya)。
３）高壓(ya)膠管(guan)的外膠層(ceng)粘在(zai)提高層(ceng)上起維護功效，一般選用(yong)(yong)氯丁(ding)膠。應留意避免 其脆化開裂(lie)而(er)危(wei)害全(quan)部橡膠軟管(guan)的使(shi)用(yong)(yong)壽命(ming)。
