１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)和(he)外(wai)(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如圖例），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即與(yu)液壓(ya)油觸碰，故(gu)規(gui)定(ding)在(zai)長(chang)期性(xing)(xing)(xing)運行狀態下不可受液體浸蝕，能(neng)補漏。在(zai)提(ti)高(gao)層(ceng)(ceng)功效下會承擔(dan)一定(ding)工作(zuo)壓(ya)力(li)。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外(wai)(wai)(wai)，危害性(xing)(xing)(xing)能(neng)的(de)(de)關(guan)(guan)鍵(jian)要(yao)素也有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度、薄(bo)厚(hou)和(he)永久性(xing)(xing)(xing)形(xing)(xing)變量(liang)。強(qiang)度和(he)永久性(xing)(xing)(xing)形(xing)(xing)變量(liang)對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害非常大。一般強(qiang)度高(gao)、縮小后(hou)的(de)(de)永久性(xing)(xing)(xing)形(xing)(xing)變量(liang)小，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好。一般是在(zai)７０～８５邵(shao)氏硬度，縮小永久性(xing)(xing)(xing)形(xing)(xing)變５０％時(shi)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)建議(yi)是為(wei)１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)壓(ya)扣(kou)時(shi)提(ti)升(sheng)其流動率，導(dao)致(zhi)不必要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套(tao)與(yu)橡膠(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸碰內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商品(pin)流通橫截面；過(guo)薄(bo)會在(zai)壓(ya)扣(kou)時(shi)被壓(ya)裂。另外(wai)(wai)(wai)內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁(bi)厚(hou)勻稱性(xing)(xing)(xing)也很重要(yao)。假(jia)如薄(bo)厚(hou)不勻，縮小后(hou)會導(dao)致(zhi)一面裂斷、一面堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表(biao)層(ceng)(ceng)出(chu)現的(de)(de)浮銹(xiu)也是危害性(xing)(xing)(xing)能(neng)品(pin)質的(de)(de)關(guan)(guan)鍵(jian)要(yao)素。
２）高壓膠(jiao)(jiao)管關鍵借助提高層(ceng)來(lai)承(cheng)(cheng)受力。手工編織(zhi)橡膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與內外(wai)黏(nian)膠(jiao)(jiao)粘緊(jin)，因(yin)為同(tong)(tong)一(yi)(yi)手工編織(zhi)層(ceng)內不(bu)(bu)銹鋼絲中(zhong)間(jian)(jian)的(de)互相(xiang)觸碰，在承(cheng)(cheng)擔(dan)(dan)氣體壓力的(de)時候會因(yin)分別伸縮式不(bu)(bu)一(yi)(yi)而導致不(bu)(bu)銹鋼絲彼此之(zhi)間(jian)(jian)的(de)摩擦(ca)而危害其使用(yong)性(xing)能(neng)。而螺(luo)旋(xuan)波(bo)紋管是由(you)盤繞(rao)方(fang)位不(bu)(bu)一(yi)(yi)樣(yang)的(de)雙層(ceng)產生一(yi)(yi)個(ge)工作中(zhong)層(ceng)，在雙層(ceng)中(zhong)間(jian)(jian)有正中(zhong)間(jian)(jian)膠(jiao)(jiao)，因(yin)而同(tong)(tong)一(yi)(yi)工作中(zhong)層(ceng)的(de)雙層(ceng)不(bu)(bu)銹鋼絲中(zhong)間(jian)(jian)沒有交(jiao)接點。因(yin)此 不(bu)(bu)容易在承(cheng)(cheng)擔(dan)(dan)氣體壓力時同(tong)(tong)于不(bu)(bu)銹鋼絲間(jian)(jian)的(de)交(jiao)叉式彎折而產生應力或磨擦(ca)磨壞。故使用(yong)性(xing)能(neng)好，能(neng)承(cheng)(cheng)擔(dan)(dan)髙壓。
３）高壓膠管(guan)(guan)的(de)(de)外膠層(ceng)粘在提高層(ceng)上起維護功效，一般選(xuan)用氯(lv)丁膠。應留意避免 其脆(cui)化開裂而危害全部橡膠軟管(guan)(guan)的(de)(de)使用壽(shou)命。
