１、橡膠軟管總成
1）高(gao)(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)由內膠(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)(gao)層(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如(ru)圖例(li)），內膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即(ji)與液壓(ya)(ya)油觸碰，故規定在(zai)(zai)長(chang)期性(xing)(xing)(xing)(xing)運行(xing)狀態下不可受液體浸蝕，能(neng)(neng)補漏。在(zai)(zai)提(ti)高(gao)(gao)層(ceng)(ceng)功效下會(hui)承擔一(yi)定工作壓(ya)(ya)力。因而，宜選用丁(ding)腈橡膠(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)粒外(wai)，危害性(xing)(xing)(xing)(xing)能(neng)(neng)的(de)(de)關(guan)鍵要(yao)(yao)素(su)也有(you)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度、薄(bo)厚和永久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)。強(qiang)度和永久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)對密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)危害非常(chang)大。一(yi)般強(qiang)度高(gao)(gao)、縮(suo)小后(hou)的(de)(de)永久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)小，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)則越好(hao)。一(yi)般是在(zai)(zai)７０～８５邵(shao)氏(shi)硬度，縮(suo)小永久性(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時(shi)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚建議是為１．５～２．５ｍｍ，太(tai)厚會(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)提(ti)升其流(liu)動(dong)率，導致不必要(yao)(yao)的(de)(de)膠(jiao)(jiao)(jiao)在(zai)(zai)接頭芯(xin)套與橡膠(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸碰內孔(kong)內沉(chen)積，減少商品流(liu)通橫(heng)截(jie)面(mian)；過薄(bo)會(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)被壓(ya)(ya)裂。另外(wai)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚勻稱性(xing)(xing)(xing)(xing)也很重要(yao)(yao)。假(jia)如(ru)薄(bo)厚不勻，縮(suo)小后(hou)會(hui)導致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)浮銹也是危害性(xing)(xing)(xing)(xing)能(neng)(neng)品質(zhi)的(de)(de)關(guan)鍵要(yao)(yao)素(su)。
２）高壓(ya)(ya)膠管關(guan)鍵(jian)借助(zhu)提高層(ceng)(ceng)(ceng)來(lai)承(cheng)受力(li)(li)。手工編織橡(xiang)膠軟(ruan)管是靠(kao)膠漿與(yu)內(nei)外黏(nian)膠粘緊，因(yin)為同一(yi)(yi)手工編織層(ceng)(ceng)(ceng)內(nei)不(bu)銹鋼絲(si)(si)中(zhong)(zhong)間的互相(xiang)觸碰，在承(cheng)擔氣體壓(ya)(ya)力(li)(li)的時候會因(yin)分別伸縮式不(bu)一(yi)(yi)而(er)導(dao)致不(bu)銹鋼絲(si)(si)彼(bi)此(ci)之間的摩擦而(er)危害其(qi)使(shi)用性能(neng)(neng)。而(er)螺旋波紋管是由(you)盤繞方位不(bu)一(yi)(yi)樣的雙(shuang)層(ceng)(ceng)(ceng)產生(sheng)一(yi)(yi)個工作中(zhong)(zhong)層(ceng)(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)(ceng)中(zhong)(zhong)間有(you)正中(zhong)(zhong)間膠，因(yin)而(er)同一(yi)(yi)工作中(zhong)(zhong)層(ceng)(ceng)(ceng)的雙(shuang)層(ceng)(ceng)(ceng)不(bu)銹鋼絲(si)(si)中(zhong)(zhong)間沒(mei)有(you)交接點。因(yin)此(ci) 不(bu)容易在承(cheng)擔氣體壓(ya)(ya)力(li)(li)時同于不(bu)銹鋼絲(si)(si)間的交叉式彎折而(er)產生(sheng)應力(li)(li)或磨擦磨壞。故使(shi)用性能(neng)(neng)好，能(neng)(neng)承(cheng)擔髙壓(ya)(ya)。
３）高壓膠(jiao)管(guan)的外膠(jiao)層粘在(zai)提(ti)高層上(shang)起維護功(gong)效，一般選用(yong)氯丁膠(jiao)。應留意避免 其脆化開裂而危害全部橡膠(jiao)軟(ruan)管(guan)的使用(yong)壽命(ming)。
