１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)由內膠(jiao)(jiao)(jiao)層(ceng)、提高(gao)層(ceng)和外(wai)膠(jiao)(jiao)(jiao)層(ceng)構成（如圖(tu)例），內膠(jiao)(jiao)(jiao)層(ceng)立即(ji)與(yu)液(ye)(ye)壓(ya)油觸碰(peng)，故規定(ding)在(zai)長(chang)期性(xing)(xing)(xing)(xing)運行狀(zhuang)態(tai)下不可(ke)受液(ye)(ye)體浸蝕，能補(bu)漏。在(zai)提高(gao)層(ceng)功效下會(hui)(hui)承擔一(yi)(yi)(yi)定(ding)工作(zuo)壓(ya)力(li)。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外(wai)，危害(hai)(hai)(hai)性(xing)(xing)(xing)(xing)能的(de)(de)(de)(de)關鍵要素(su)也有內膠(jiao)(jiao)(jiao)層(ceng)的(de)(de)(de)(de)強度(du)、薄(bo)(bo)厚和永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)。強度(du)和永(yong)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)能危害(hai)(hai)(hai)非常大(da)。一(yi)(yi)(yi)般強度(du)高(gao)、縮小(xiao)后的(de)(de)(de)(de)永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)小(xiao)，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能則越好。一(yi)(yi)(yi)般是在(zai)７０～８５邵氏硬度(du)，縮小(xiao)永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時。內膠(jiao)(jiao)(jiao)層(ceng)薄(bo)(bo)厚建議(yi)是為１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)壓(ya)扣時提升其流動率，導致(zhi)不必(bi)要的(de)(de)(de)(de)膠(jiao)(jiao)(jiao)在(zai)接(jie)頭芯套與(yu)橡膠(jiao)(jiao)(jiao)軟管(guan)(guan)的(de)(de)(de)(de)觸碰(peng)內孔內沉積，減少商品(pin)流通橫(heng)截(jie)面(mian)；過薄(bo)(bo)會(hui)(hui)在(zai)壓(ya)扣時被(bei)壓(ya)裂。另外(wai)內膠(jiao)(jiao)(jiao)層(ceng)壁厚勻稱(cheng)性(xing)(xing)(xing)(xing)也很重要。假如薄(bo)(bo)厚不勻，縮小(xiao)后會(hui)(hui)導致(zhi)一(yi)(yi)(yi)面(mian)裂斷、一(yi)(yi)(yi)面(mian)堆膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層(ceng)表層(ceng)出現(xian)的(de)(de)(de)(de)浮銹(xiu)也是危害(hai)(hai)(hai)性(xing)(xing)(xing)(xing)能品(pin)質的(de)(de)(de)(de)關鍵要素(su)。
２）高壓(ya)(ya)(ya)膠(jiao)管關鍵借助提高層(ceng)(ceng)(ceng)來承受力(li)。手工(gong)(gong)編織橡(xiang)膠(jiao)軟(ruan)管是(shi)靠膠(jiao)漿與內外黏(nian)膠(jiao)粘緊，因為同(tong)一(yi)手工(gong)(gong)編織層(ceng)(ceng)(ceng)內不(bu)銹鋼(gang)絲(si)中(zhong)間(jian)(jian)的(de)互相觸碰，在(zai)(zai)承擔氣體(ti)壓(ya)(ya)(ya)力(li)的(de)時候會(hui)因分別伸縮(suo)式(shi)不(bu)一(yi)而(er)導(dao)致不(bu)銹鋼(gang)絲(si)彼(bi)此之間(jian)(jian)的(de)摩擦而(er)危害其使(shi)(shi)用性(xing)能。而(er)螺旋波紋管是(shi)由盤繞方(fang)位不(bu)一(yi)樣的(de)雙層(ceng)(ceng)(ceng)產生一(yi)個工(gong)(gong)作(zuo)中(zhong)層(ceng)(ceng)(ceng)，在(zai)(zai)雙層(ceng)(ceng)(ceng)中(zhong)間(jian)(jian)有正中(zhong)間(jian)(jian)膠(jiao)，因而(er)同(tong)一(yi)工(gong)(gong)作(zuo)中(zhong)層(ceng)(ceng)(ceng)的(de)雙層(ceng)(ceng)(ceng)不(bu)銹鋼(gang)絲(si)中(zhong)間(jian)(jian)沒有交接點。因此 不(bu)容易在(zai)(zai)承擔氣體(ti)壓(ya)(ya)(ya)力(li)時同(tong)于不(bu)銹鋼(gang)絲(si)間(jian)(jian)的(de)交叉式(shi)彎折而(er)產生應力(li)或(huo)磨擦磨壞。故使(shi)(shi)用性(xing)能好(hao)，能承擔髙(gao)壓(ya)(ya)(ya)。
３）高(gao)壓膠管(guan)的外(wai)膠層(ceng)粘(zhan)在(zai)提高(gao)層(ceng)上起維護功效，一般選(xuan)用(yong)(yong)氯(lv)丁膠。應留意避免 其(qi)脆化(hua)開裂而危(wei)害全部橡膠軟管(guan)的使用(yong)(yong)壽(shou)命(ming)。
