１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高(gao)(gao)層(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖例），內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與液壓(ya)油觸碰，故規(gui)定在(zai)(zai)長期性(xing)運(yun)行狀態下(xia)不(bu)可受液體(ti)浸(jin)蝕，能補漏。在(zai)(zai)提高(gao)(gao)層(ceng)(ceng)(ceng)功效下(xia)會(hui)承擔一定工作壓(ya)力。因而，宜選用丁(ding)腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危害(hai)性(xing)能的(de)(de)(de)關(guan)鍵要(yao)(yao)素也(ye)有內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)(de)(de)強度(du)、薄(bo)厚和(he)永(yong)(yong)久(jiu)性(xing)形變(bian)(bian)(bian)(bian)量。強度(du)和(he)永(yong)(yong)久(jiu)性(xing)形變(bian)(bian)(bian)(bian)量對密(mi)封(feng)性(xing)性(xing)能危害(hai)非常(chang)大(da)。一般(ban)強度(du)高(gao)(gao)、縮小后(hou)的(de)(de)(de)永(yong)(yong)久(jiu)性(xing)形變(bian)(bian)(bian)(bian)量小，密(mi)封(feng)性(xing)性(xing)能則(ze)越(yue)好。一般(ban)是(shi)在(zai)(zai)７０～８５邵氏(shi)硬度(du)，縮小永(yong)(yong)久(jiu)性(xing)形變(bian)(bian)(bian)(bian)５０％時。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建議是(shi)為１．５～２．５ｍｍ，太厚會(hui)在(zai)(zai)壓(ya)扣(kou)(kou)時提升(sheng)其(qi)流動(dong)率，導致不(bu)必要(yao)(yao)的(de)(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭(tou)芯套與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)(de)觸碰內孔內沉積(ji)，減少商品流通橫截面；過薄(bo)會(hui)在(zai)(zai)壓(ya)扣(kou)(kou)時被壓(ya)裂(lie)。另外內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻稱性(xing)也(ye)很重要(yao)(yao)。假(jia)如薄(bo)厚不(bu)勻，縮小后(hou)會(hui)導致一面裂(lie)斷、一面堆(dui)膠(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)(de)(de)浮銹也(ye)是(shi)危害(hai)性(xing)能品質的(de)(de)(de)關(guan)鍵要(yao)(yao)素。
２）高壓(ya)(ya)膠(jiao)管關(guan)鍵借助提(ti)高層(ceng)來承受力(li)(li)(li)。手(shou)工(gong)編織(zhi)(zhi)橡膠(jiao)軟(ruan)管是(shi)靠膠(jiao)漿與內外黏膠(jiao)粘緊(jin)，因為同(tong)(tong)一手(shou)工(gong)編織(zhi)(zhi)層(ceng)內不(bu)銹(xiu)(xiu)鋼絲中間(jian)(jian)(jian)的(de)(de)互相(xiang)觸碰，在(zai)(zai)承擔(dan)氣體(ti)壓(ya)(ya)力(li)(li)(li)的(de)(de)時(shi)候會因分別伸縮(suo)式不(bu)一而(er)導致不(bu)銹(xiu)(xiu)鋼絲彼此之間(jian)(jian)(jian)的(de)(de)摩擦(ca)而(er)危害(hai)其使用(yong)性(xing)能(neng)。而(er)螺旋波紋管是(shi)由(you)盤繞(rao)方位不(bu)一樣的(de)(de)雙層(ceng)產生一個工(gong)作中層(ceng)，在(zai)(zai)雙層(ceng)中間(jian)(jian)(jian)有(you)正中間(jian)(jian)(jian)膠(jiao)，因而(er)同(tong)(tong)一工(gong)作中層(ceng)的(de)(de)雙層(ceng)不(bu)銹(xiu)(xiu)鋼絲中間(jian)(jian)(jian)沒(mei)有(you)交接點。因此 不(bu)容易(yi)在(zai)(zai)承擔(dan)氣體(ti)壓(ya)(ya)力(li)(li)(li)時(shi)同(tong)(tong)于(yu)不(bu)銹(xiu)(xiu)鋼絲間(jian)(jian)(jian)的(de)(de)交叉式彎(wan)折而(er)產生應力(li)(li)(li)或磨(mo)擦(ca)磨(mo)壞。故使用(yong)性(xing)能(neng)好，能(neng)承擔(dan)髙壓(ya)(ya)。
３）高壓(ya)膠(jiao)管的外(wai)膠(jiao)層粘在提(ti)高層上起(qi)維護(hu)功(gong)效(xiao)，一般(ban)選(xuan)用氯丁(ding)膠(jiao)。應留意(yi)避免 其脆化開(kai)裂(lie)而危害(hai)全部橡膠(jiao)軟管的使用壽命。
