１、橡膠軟管總成
1）高(gao)(gao)壓膠(jiao)(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)高(gao)(gao)層(ceng)(ceng)(ceng)和外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如(ru)圖例(li)），內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與(yu)液壓油觸碰(peng)，故規定(ding)(ding)在(zai)(zai)長期性(xing)(xing)(xing)(xing)運行狀態下不可受液體浸蝕(shi)，能補漏。在(zai)(zai)提(ti)高(gao)(gao)層(ceng)(ceng)(ceng)功效下會(hui)承擔一(yi)定(ding)(ding)工作壓力。因(yin)而(er)，宜選用丁(ding)腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)(wai)，危害性(xing)(xing)(xing)(xing)能的(de)關鍵要(yao)素也有內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強度(du)、薄(bo)厚和永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)(liang)。強度(du)和永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)(liang)對密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能危害非常大。一(yi)般強度(du)高(gao)(gao)、縮小后的(de)永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)(liang)小，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能則越好。一(yi)般是(shi)在(zai)(zai)７０～８５邵氏硬度(du)，縮小永(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建議(yi)是(shi)為１．５～２．５ｍｍ，太(tai)厚會(hui)在(zai)(zai)壓扣時提(ti)升其(qi)流動(dong)率(lv)，導致不必要(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套與(yu)橡膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰(peng)內(nei)孔內(nei)沉積，減少商品流通(tong)橫(heng)截面(mian)；過薄(bo)會(hui)在(zai)(zai)壓扣時被壓裂。另外(wai)(wai)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁(bi)厚勻(yun)稱性(xing)(xing)(xing)(xing)也很重要(yao)。假如(ru)薄(bo)厚不勻(yun)，縮小后會(hui)導致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現(xian)的(de)浮銹也是(shi)危害性(xing)(xing)(xing)(xing)能品質的(de)關鍵要(yao)素。
２）高(gao)壓(ya)膠(jiao)管關鍵借助提高(gao)層(ceng)來承受力(li)。手(shou)工(gong)編織(zhi)橡膠(jiao)軟管是靠膠(jiao)漿(jiang)與內(nei)外黏膠(jiao)粘緊，因(yin)為同(tong)一(yi)手(shou)工(gong)編織(zhi)層(ceng)內(nei)不(bu)(bu)銹(xiu)鋼絲(si)(si)中(zhong)(zhong)(zhong)間(jian)的(de)互相觸碰，在(zai)(zai)承擔氣(qi)(qi)體(ti)壓(ya)力(li)的(de)時候會(hui)因(yin)分別伸縮(suo)式不(bu)(bu)一(yi)而導致不(bu)(bu)銹(xiu)鋼絲(si)(si)彼此之間(jian)的(de)摩(mo)擦而危害其使(shi)用性能。而螺旋波紋管是由盤繞方位不(bu)(bu)一(yi)樣的(de)雙層(ceng)產(chan)生一(yi)個工(gong)作(zuo)中(zhong)(zhong)(zhong)層(ceng)，在(zai)(zai)雙層(ceng)中(zhong)(zhong)(zhong)間(jian)有正中(zhong)(zhong)(zhong)間(jian)膠(jiao)，因(yin)而同(tong)一(yi)工(gong)作(zuo)中(zhong)(zhong)(zhong)層(ceng)的(de)雙層(ceng)不(bu)(bu)銹(xiu)鋼絲(si)(si)中(zhong)(zhong)(zhong)間(jian)沒有交(jiao)接點。因(yin)此 不(bu)(bu)容易在(zai)(zai)承擔氣(qi)(qi)體(ti)壓(ya)力(li)時同(tong)于不(bu)(bu)銹(xiu)鋼絲(si)(si)間(jian)的(de)交(jiao)叉式彎折而產(chan)生應力(li)或(huo)磨(mo)擦磨(mo)壞。故使(shi)用性能好，能承擔髙(gao)壓(ya)。
３）高壓膠(jiao)管的(de)外(wai)膠(jiao)層粘(zhan)在提(ti)高層上起(qi)維護(hu)功(gong)效(xiao)，一(yi)般(ban)選用氯(lv)丁膠(jiao)。應(ying)留意避(bi)免 其脆化開裂而危害全部橡膠(jiao)軟管的(de)使用壽命。
