１、橡膠軟管總成
1）高(gao)壓(ya)膠管由內(nei)(nei)膠層(ceng)、提高(gao)層(ceng)和外膠層(ceng)構成(cheng)（如圖例），內(nei)(nei)膠層(ceng)立(li)即與液壓(ya)油觸碰(peng)，故規定在(zai)長期性(xing)(xing)(xing)(xing)(xing)運行狀態下(xia)不(bu)可受(shou)液體浸蝕，能(neng)補漏。在(zai)提高(gao)層(ceng)功(gong)效下(xia)會(hui)承擔一(yi)定工作壓(ya)力。因而，宜選(xuan)用丁(ding)腈橡(xiang)膠，除塑膠粒外，危(wei)害性(xing)(xing)(xing)(xing)(xing)能(neng)的(de)(de)關(guan)鍵(jian)(jian)要素也(ye)有內(nei)(nei)膠層(ceng)的(de)(de)強(qiang)度(du)、薄(bo)厚(hou)和永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)。強(qiang)度(du)和永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)對密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)危(wei)害非常(chang)大。一(yi)般強(qiang)度(du)高(gao)、縮小后(hou)的(de)(de)永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)小，密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)則越(yue)好。一(yi)般是在(zai)７０～８５邵氏硬(ying)度(du)，縮小永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)５０％時(shi)。內(nei)(nei)膠層(ceng)薄(bo)厚(hou)建議是為(wei)１．５～２．５ｍｍ，太厚(hou)會(hui)在(zai)壓(ya)扣時(shi)提升(sheng)其流(liu)(liu)動率(lv)，導致(zhi)不(bu)必要的(de)(de)膠在(zai)接(jie)頭芯(xin)套與橡(xiang)膠軟(ruan)管的(de)(de)觸碰(peng)內(nei)(nei)孔內(nei)(nei)沉(chen)積(ji)，減少商(shang)品(pin)流(liu)(liu)通橫截(jie)面(mian)(mian)(mian)；過薄(bo)會(hui)在(zai)壓(ya)扣時(shi)被壓(ya)裂。另外內(nei)(nei)膠層(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)(xing)(xing)也(ye)很重要。假如薄(bo)厚(hou)不(bu)勻，縮小后(hou)會(hui)導致(zhi)一(yi)面(mian)(mian)(mian)裂斷、一(yi)面(mian)(mian)(mian)堆膠。內(nei)(nei)膠層(ceng)表(biao)層(ceng)出現的(de)(de)浮(fu)銹也(ye)是危(wei)害性(xing)(xing)(xing)(xing)(xing)能(neng)品(pin)質(zhi)的(de)(de)關(guan)鍵(jian)(jian)要素。
２）高(gao)壓(ya)膠(jiao)管關(guan)鍵借助提(ti)高(gao)層(ceng)(ceng)來(lai)承受力(li)(li)。手(shou)工(gong)(gong)編(bian)織橡(xiang)膠(jiao)軟管是靠膠(jiao)漿(jiang)與內外(wai)黏膠(jiao)粘(zhan)緊，因(yin)(yin)為同一(yi)手(shou)工(gong)(gong)編(bian)織層(ceng)(ceng)內不銹(xiu)(xiu)鋼(gang)(gang)絲(si)中間(jian)(jian)(jian)的(de)互相(xiang)觸碰，在(zai)(zai)承擔氣體壓(ya)力(li)(li)的(de)時候會因(yin)(yin)分別伸縮式(shi)不一(yi)而(er)導致不銹(xiu)(xiu)鋼(gang)(gang)絲(si)彼(bi)此之間(jian)(jian)(jian)的(de)摩(mo)擦而(er)危(wei)害(hai)其使(shi)用(yong)(yong)性(xing)能。而(er)螺旋波紋管是由(you)盤繞方位不一(yi)樣的(de)雙(shuang)層(ceng)(ceng)產生一(yi)個工(gong)(gong)作(zuo)中層(ceng)(ceng)，在(zai)(zai)雙(shuang)層(ceng)(ceng)中間(jian)(jian)(jian)有(you)正中間(jian)(jian)(jian)膠(jiao)，因(yin)(yin)而(er)同一(yi)工(gong)(gong)作(zuo)中層(ceng)(ceng)的(de)雙(shuang)層(ceng)(ceng)不銹(xiu)(xiu)鋼(gang)(gang)絲(si)中間(jian)(jian)(jian)沒有(you)交(jiao)接(jie)點。因(yin)(yin)此 不容易在(zai)(zai)承擔氣體壓(ya)力(li)(li)時同于不銹(xiu)(xiu)鋼(gang)(gang)絲(si)間(jian)(jian)(jian)的(de)交(jiao)叉式(shi)彎折而(er)產生應力(li)(li)或磨擦磨壞。故使(shi)用(yong)(yong)性(xing)能好(hao)，能承擔髙壓(ya)。
３）高壓膠(jiao)(jiao)(jiao)管(guan)的外膠(jiao)(jiao)(jiao)層粘在提高層上起維護(hu)功效(xiao)，一般選用氯丁膠(jiao)(jiao)(jiao)。應留意避免 其脆化開裂(lie)而危(wei)害全部橡膠(jiao)(jiao)(jiao)軟(ruan)管(guan)的使用壽命(ming)。
