１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)管由內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提(ti)(ti)高層(ceng)(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成(cheng)（如圖例），內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即與液壓(ya)油觸碰，故規定在(zai)長期性(xing)(xing)運行狀態下(xia)不可受液體浸(jin)蝕(shi)，能補漏。在(zai)提(ti)(ti)高層(ceng)(ceng)(ceng)(ceng)功效下(xia)會承擔一(yi)定工作壓(ya)力。因(yin)而(er)，宜選用丁腈橡(xiang)(xiang)膠(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)粒外，危害(hai)性(xing)(xing)能的(de)關鍵要素(su)也有內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)強(qiang)度(du)(du)(du)、薄(bo)(bo)厚(hou)(hou)和(he)永久性(xing)(xing)形(xing)變(bian)(bian)量(liang)。強(qiang)度(du)(du)(du)和(he)永久性(xing)(xing)形(xing)變(bian)(bian)量(liang)對(dui)密封性(xing)(xing)性(xing)(xing)能危害(hai)非常大。一(yi)般強(qiang)度(du)(du)(du)高、縮(suo)(suo)小(xiao)(xiao)后的(de)永久性(xing)(xing)形(xing)變(bian)(bian)量(liang)小(xiao)(xiao)，密封性(xing)(xing)性(xing)(xing)能則越好。一(yi)般是在(zai)７０～８５邵氏硬度(du)(du)(du)，縮(suo)(suo)小(xiao)(xiao)永久性(xing)(xing)形(xing)變(bian)(bian)５０％時(shi)(shi)。內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄(bo)(bo)厚(hou)(hou)建議是為１．５～２．５ｍｍ，太厚(hou)(hou)會在(zai)壓(ya)扣時(shi)(shi)提(ti)(ti)升其流動(dong)率，導(dao)致不必要的(de)膠(jiao)(jiao)在(zai)接(jie)頭芯套與橡(xiang)(xiang)膠(jiao)(jiao)軟管的(de)觸碰內孔(kong)內沉積，減少商品(pin)流通橫(heng)截面(mian)(mian)；過薄(bo)(bo)會在(zai)壓(ya)扣時(shi)(shi)被壓(ya)裂(lie)。另外內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚(hou)(hou)勻(yun)(yun)稱性(xing)(xing)也很重(zhong)要。假如薄(bo)(bo)厚(hou)(hou)不勻(yun)(yun)，縮(suo)(suo)小(xiao)(xiao)后會導(dao)致一(yi)面(mian)(mian)裂(lie)斷、一(yi)面(mian)(mian)堆(dui)膠(jiao)(jiao)。內膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出現的(de)浮銹也是危害(hai)性(xing)(xing)能品(pin)質(zhi)的(de)關鍵要素(su)。
２）高(gao)壓膠(jiao)管(guan)關鍵借助提(ti)高(gao)層(ceng)(ceng)(ceng)來(lai)承(cheng)(cheng)受力。手工編織(zhi)橡膠(jiao)軟管(guan)是靠膠(jiao)漿與內外黏膠(jiao)粘緊，因(yin)為同(tong)一(yi)(yi)手工編織(zhi)層(ceng)(ceng)(ceng)內不銹(xiu)(xiu)鋼絲中(zhong)間(jian)的互相觸碰，在承(cheng)(cheng)擔(dan)氣(qi)體壓力的時(shi)候(hou)會因(yin)分別伸縮式(shi)不一(yi)(yi)而導致不銹(xiu)(xiu)鋼絲彼(bi)此之間(jian)的摩擦而危害其使(shi)用性能。而螺旋波紋(wen)管(guan)是由盤繞方(fang)位(wei)不一(yi)(yi)樣的雙層(ceng)(ceng)(ceng)產生一(yi)(yi)個工作(zuo)中(zhong)層(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)中(zhong)間(jian)有正中(zhong)間(jian)膠(jiao)，因(yin)而同(tong)一(yi)(yi)工作(zuo)中(zhong)層(ceng)(ceng)(ceng)的雙層(ceng)(ceng)(ceng)不銹(xiu)(xiu)鋼絲中(zhong)間(jian)沒(mei)有交接點。因(yin)此 不容易在承(cheng)(cheng)擔(dan)氣(qi)體壓力時(shi)同(tong)于不銹(xiu)(xiu)鋼絲間(jian)的交叉式(shi)彎折(zhe)而產生應力或磨(mo)擦磨(mo)壞(huai)。故使(shi)用性能好，能承(cheng)(cheng)擔(dan)髙壓。
３）高(gao)壓膠管的外(wai)膠層(ceng)(ceng)粘在提(ti)高(gao)層(ceng)(ceng)上(shang)起維護功效(xiao)，一般選用氯丁膠。應留意避免(mian) 其(qi)脆化開裂而危(wei)害全部橡膠軟管的使用壽命。
