１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)管由內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提(ti)(ti)高(gao)層(ceng)(ceng)(ceng)(ceng)和(he)外(wai)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如(ru)圖例(li)），內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立(li)即與(yu)液壓(ya)(ya)油(you)觸碰(peng)，故規定(ding)在(zai)(zai)長期(qi)性(xing)(xing)(xing)運(yun)行狀態下不可受液體(ti)浸蝕，能(neng)補漏。在(zai)(zai)提(ti)(ti)高(gao)層(ceng)(ceng)(ceng)(ceng)功(gong)效下會(hui)(hui)承(cheng)擔一(yi)定(ding)工(gong)作壓(ya)(ya)力。因而，宜選用丁腈橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外(wai)，危害(hai)性(xing)(xing)(xing)能(neng)的(de)關鍵要素也(ye)有內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)強度(du)、薄(bo)厚和(he)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變量。強度(du)和(he)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變量對密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害(hai)非常大。一(yi)般強度(du)高(gao)、縮小后的(de)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變量小，密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好。一(yi)般是在(zai)(zai)７０～８５邵氏(shi)硬度(du)，縮小永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變５０％時(shi)(shi)。內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄(bo)厚建議是為１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)(shi)提(ti)(ti)升其流動率，導致(zhi)不必要的(de)膠(jiao)(jiao)在(zai)(zai)接頭芯套與(yu)橡膠(jiao)(jiao)軟管的(de)觸碰(peng)內(nei)孔內(nei)沉積，減(jian)少(shao)商品(pin)流通橫截面；過薄(bo)會(hui)(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)(shi)被(bei)壓(ya)(ya)裂。另外(wai)內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁(bi)厚勻稱(cheng)性(xing)(xing)(xing)也(ye)很重(zhong)要。假如(ru)薄(bo)厚不勻，縮小后會(hui)(hui)導致(zhi)一(yi)面裂斷(duan)、一(yi)面堆膠(jiao)(jiao)。內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出現的(de)浮(fu)銹也(ye)是危害(hai)性(xing)(xing)(xing)能(neng)品(pin)質的(de)關鍵要素。
２）高壓(ya)膠(jiao)管(guan)關鍵借(jie)助提高層(ceng)(ceng)(ceng)來承受力。手工(gong)(gong)編(bian)織橡膠(jiao)軟管(guan)是(shi)靠膠(jiao)漿與內外黏(nian)膠(jiao)粘緊，因為同(tong)一(yi)手工(gong)(gong)編(bian)織層(ceng)(ceng)(ceng)內不(bu)(bu)銹(xiu)鋼絲(si)中(zhong)間(jian)的(de)互相(xiang)觸碰，在承擔(dan)氣體壓(ya)力的(de)時候會因分別伸(shen)縮式(shi)不(bu)(bu)一(yi)而導(dao)致不(bu)(bu)銹(xiu)鋼絲(si)彼此(ci)(ci)之間(jian)的(de)摩(mo)擦而危害其(qi)使用(yong)性能。而螺旋波紋管(guan)是(shi)由盤繞(rao)方位不(bu)(bu)一(yi)樣的(de)雙層(ceng)(ceng)(ceng)產生一(yi)個(ge)工(gong)(gong)作中(zhong)層(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)中(zhong)間(jian)有正中(zhong)間(jian)膠(jiao)，因而同(tong)一(yi)工(gong)(gong)作中(zhong)層(ceng)(ceng)(ceng)的(de)雙層(ceng)(ceng)(ceng)不(bu)(bu)銹(xiu)鋼絲(si)中(zhong)間(jian)沒(mei)有交(jiao)接點。因此(ci)(ci) 不(bu)(bu)容易在承擔(dan)氣體壓(ya)力時同(tong)于不(bu)(bu)銹(xiu)鋼絲(si)間(jian)的(de)交(jiao)叉式(shi)彎(wan)折而產生應(ying)力或磨擦磨壞。故使用(yong)性能好，能承擔(dan)髙壓(ya)。
３）高壓(ya)膠(jiao)管的外膠(jiao)層(ceng)粘在提高層(ceng)上起維護功效，一般選用氯丁膠(jiao)。應(ying)留意避免(mian) 其脆(cui)化(hua)開(kai)裂而危害(hai)全部橡膠(jiao)軟管的使用壽命(ming)。
