１、橡膠軟管總成
1）高(gao)壓膠(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)(ceng)(ceng)和外膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)構成(cheng)（如圖例），內膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)立即與液壓油觸(chu)碰，故規(gui)定(ding)在(zai)長期性(xing)(xing)運(yun)行狀態下不可受(shou)液體(ti)浸(jin)蝕，能補(bu)漏。在(zai)提高(gao)層(ceng)(ceng)(ceng)(ceng)(ceng)功效(xiao)下會(hui)承(cheng)擔一定(ding)工作壓力。因而，宜選(xuan)用丁腈橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒(li)外，危害性(xing)(xing)能的(de)(de)關(guan)鍵要(yao)素(su)也有內膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)強度、薄(bo)厚(hou)和永(yong)久性(xing)(xing)形(xing)(xing)變(bian)量。強度和永(yong)久性(xing)(xing)形(xing)(xing)變(bian)量對密封性(xing)(xing)性(xing)(xing)能危害非常大。一般(ban)(ban)強度高(gao)、縮小后的(de)(de)永(yong)久性(xing)(xing)形(xing)(xing)變(bian)量小，密封性(xing)(xing)性(xing)(xing)能則越(yue)好。一般(ban)(ban)是在(zai)７０～８５邵(shao)氏硬度，縮小永(yong)久性(xing)(xing)形(xing)(xing)變(bian)５０％時(shi)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)薄(bo)厚(hou)建(jian)議是為１．５～２．５ｍｍ，太(tai)厚(hou)會(hui)在(zai)壓扣時(shi)提升其(qi)流動率，導(dao)(dao)致不必要(yao)的(de)(de)膠(jiao)(jiao)(jiao)在(zai)接頭芯套(tao)與橡膠(jiao)(jiao)(jiao)軟管的(de)(de)觸(chu)碰內孔內沉(chen)積，減少商品流通橫截面(mian)；過薄(bo)會(hui)在(zai)壓扣時(shi)被壓裂(lie)。另(ling)外內膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)壁厚(hou)勻稱(cheng)性(xing)(xing)也很重要(yao)。假如薄(bo)厚(hou)不勻，縮小后會(hui)導(dao)(dao)致一面(mian)裂(lie)斷、一面(mian)堆(dui)膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)(ceng)(ceng)出現的(de)(de)浮銹也是危害性(xing)(xing)能品質(zhi)的(de)(de)關(guan)鍵要(yao)素(su)。
２）高壓(ya)膠(jiao)(jiao)(jiao)管(guan)關鍵(jian)借助提高層(ceng)來承(cheng)受力(li)(li)。手工(gong)編織橡(xiang)膠(jiao)(jiao)(jiao)軟管(guan)是靠膠(jiao)(jiao)(jiao)漿與內外(wai)黏膠(jiao)(jiao)(jiao)粘緊(jin)，因(yin)為同(tong)一(yi)手工(gong)編織層(ceng)內不(bu)(bu)銹(xiu)鋼絲(si)(si)中間(jian)的互(hu)相觸碰，在承(cheng)擔氣(qi)體壓(ya)力(li)(li)的時(shi)(shi)候會因(yin)分別伸(shen)縮(suo)式不(bu)(bu)一(yi)而導(dao)致不(bu)(bu)銹(xiu)鋼絲(si)(si)彼此(ci)之間(jian)的摩(mo)擦(ca)而危害其(qi)使用性(xing)能(neng)(neng)。而螺(luo)旋波紋管(guan)是由盤繞(rao)方位不(bu)(bu)一(yi)樣的雙層(ceng)產生一(yi)個工(gong)作中層(ceng)，在雙層(ceng)中間(jian)有(you)正中間(jian)膠(jiao)(jiao)(jiao)，因(yin)而同(tong)一(yi)工(gong)作中層(ceng)的雙層(ceng)不(bu)(bu)銹(xiu)鋼絲(si)(si)中間(jian)沒有(you)交接點。因(yin)此(ci) 不(bu)(bu)容易在承(cheng)擔氣(qi)體壓(ya)力(li)(li)時(shi)(shi)同(tong)于不(bu)(bu)銹(xiu)鋼絲(si)(si)間(jian)的交叉式彎折而產生應力(li)(li)或磨擦(ca)磨壞。故(gu)使用性(xing)能(neng)(neng)好，能(neng)(neng)承(cheng)擔髙壓(ya)。
３）高壓膠(jiao)(jiao)管(guan)(guan)的(de)外膠(jiao)(jiao)層(ceng)粘在提高層(ceng)上(shang)起維護(hu)功效，一般選用(yong)(yong)氯丁膠(jiao)(jiao)。應(ying)留意避免(mian) 其脆化開裂(lie)而危害全部(bu)橡膠(jiao)(jiao)軟管(guan)(guan)的(de)使用(yong)(yong)壽命(ming)。
