１、橡膠軟管總成
1）高(gao)壓(ya)(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)、提高(gao)層(ceng)和(he)外(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)構成（如圖例(li)），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)立即與液壓(ya)(ya)(ya)油觸碰(peng)，故規定在(zai)(zai)(zai)長期性(xing)(xing)運行狀態下不可受液體浸蝕(shi)，能(neng)(neng)補漏(lou)。在(zai)(zai)(zai)提高(gao)層(ceng)功效下會(hui)(hui)承擔一(yi)定工作壓(ya)(ya)(ya)力。因而，宜選用丁腈(jing)橡膠(jiao)(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)，危(wei)害性(xing)(xing)能(neng)(neng)的(de)(de)關鍵要(yao)素(su)也(ye)有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)的(de)(de)強(qiang)(qiang)度、薄(bo)厚和(he)永久(jiu)性(xing)(xing)形(xing)變(bian)量。強(qiang)(qiang)度和(he)永久(jiu)性(xing)(xing)形(xing)變(bian)量對密封性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害非常大(da)。一(yi)般強(qiang)(qiang)度高(gao)、縮小(xiao)(xiao)后(hou)(hou)的(de)(de)永久(jiu)性(xing)(xing)形(xing)變(bian)量小(xiao)(xiao)，密封性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好。一(yi)般是在(zai)(zai)(zai)７０～８５邵氏硬度，縮小(xiao)(xiao)永久(jiu)性(xing)(xing)形(xing)變(bian)５０％時(shi)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)薄(bo)厚建(jian)議(yi)是為１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)(zai)(zai)壓(ya)(ya)(ya)扣時(shi)提升其(qi)流(liu)動率(lv)，導致不必要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)(zai)接頭(tou)芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸碰(peng)內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積(ji)，減少商(shang)品流(liu)通橫(heng)截面(mian)(mian)；過薄(bo)會(hui)(hui)在(zai)(zai)(zai)壓(ya)(ya)(ya)扣時(shi)被壓(ya)(ya)(ya)裂。另外(wai)內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚勻稱性(xing)(xing)也(ye)很重要(yao)。假(jia)如薄(bo)厚不勻，縮小(xiao)(xiao)后(hou)(hou)會(hui)(hui)導致一(yi)面(mian)(mian)裂斷、一(yi)面(mian)(mian)堆(dui)膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)表層(ceng)出現(xian)的(de)(de)浮銹也(ye)是危(wei)害性(xing)(xing)能(neng)(neng)品質的(de)(de)關鍵要(yao)素(su)。
２）高(gao)壓(ya)膠(jiao)管關鍵借助提高(gao)層(ceng)來承受力(li)(li)。手(shou)工(gong)(gong)編織橡膠(jiao)軟管是靠膠(jiao)漿與內外黏(nian)膠(jiao)粘緊(jin)，因(yin)為同一(yi)手(shou)工(gong)(gong)編織層(ceng)內不(bu)(bu)銹鋼(gang)絲(si)中(zhong)間(jian)的(de)互相觸碰，在承擔(dan)(dan)氣(qi)體壓(ya)力(li)(li)的(de)時(shi)候會(hui)因(yin)分別伸(shen)縮式(shi)不(bu)(bu)一(yi)而(er)(er)導致不(bu)(bu)銹鋼(gang)絲(si)彼此之間(jian)的(de)摩擦(ca)(ca)而(er)(er)危害其使用性能(neng)。而(er)(er)螺旋波紋管是由盤繞方位不(bu)(bu)一(yi)樣的(de)雙(shuang)層(ceng)產生(sheng)一(yi)個工(gong)(gong)作中(zhong)層(ceng)，在雙(shuang)層(ceng)中(zhong)間(jian)有(you)正中(zhong)間(jian)膠(jiao)，因(yin)而(er)(er)同一(yi)工(gong)(gong)作中(zhong)層(ceng)的(de)雙(shuang)層(ceng)不(bu)(bu)銹鋼(gang)絲(si)中(zhong)間(jian)沒有(you)交接(jie)點。因(yin)此 不(bu)(bu)容易在承擔(dan)(dan)氣(qi)體壓(ya)力(li)(li)時(shi)同于不(bu)(bu)銹鋼(gang)絲(si)間(jian)的(de)交叉式(shi)彎(wan)折而(er)(er)產生(sheng)應力(li)(li)或磨(mo)擦(ca)(ca)磨(mo)壞(huai)。故使用性能(neng)好，能(neng)承擔(dan)(dan)髙壓(ya)。
３）高壓膠(jiao)管的外(wai)膠(jiao)層粘在提高層上起維護(hu)功效(xiao)，一(yi)般選用(yong)(yong)氯丁膠(jiao)。應留意避免 其脆化開裂而危害全(quan)部橡膠(jiao)軟(ruan)管的使用(yong)(yong)壽(shou)命。
