１、橡膠軟管總成
1）高(gao)壓膠管(guan)由(you)內膠層(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)和(he)外(wai)(wai)膠層(ceng)(ceng)構成（如(ru)圖(tu)例），內膠層(ceng)(ceng)立即與(yu)液壓油觸碰，故(gu)規定(ding)在長期(qi)性(xing)(xing)(xing)運行狀(zhuang)態下不(bu)可受液體浸蝕，能補漏。在提(ti)高(gao)層(ceng)(ceng)功效下會(hui)(hui)承擔一(yi)定(ding)工(gong)作壓力。因而，宜(yi)選用(yong)丁腈橡膠，除塑(su)膠粒外(wai)(wai)，危(wei)害(hai)(hai)性(xing)(xing)(xing)能的(de)關鍵要(yao)素也有內膠層(ceng)(ceng)的(de)強度(du)(du)、薄(bo)厚和(he)永久性(xing)(xing)(xing)形(xing)(xing)變量(liang)。強度(du)(du)和(he)永久性(xing)(xing)(xing)形(xing)(xing)變量(liang)對密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能危(wei)害(hai)(hai)非常大。一(yi)般強度(du)(du)高(gao)、縮小后的(de)永久性(xing)(xing)(xing)形(xing)(xing)變量(liang)小，密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能則(ze)越好。一(yi)般是(shi)在７０～８５邵(shao)氏硬度(du)(du)，縮小永久性(xing)(xing)(xing)形(xing)(xing)變５０％時。內膠層(ceng)(ceng)薄(bo)厚建(jian)議(yi)是(shi)為１．５～２．５ｍｍ，太厚會(hui)(hui)在壓扣時提(ti)升其流動率，導(dao)致不(bu)必要(yao)的(de)膠在接頭芯(xin)套與(yu)橡膠軟管(guan)的(de)觸碰內孔內沉積(ji)，減(jian)少商品流通橫(heng)截面(mian)(mian)；過薄(bo)會(hui)(hui)在壓扣時被壓裂(lie)。另(ling)外(wai)(wai)內膠層(ceng)(ceng)壁厚勻稱性(xing)(xing)(xing)也很重要(yao)。假如(ru)薄(bo)厚不(bu)勻，縮小后會(hui)(hui)導(dao)致一(yi)面(mian)(mian)裂(lie)斷、一(yi)面(mian)(mian)堆膠。內膠層(ceng)(ceng)表(biao)層(ceng)(ceng)出現的(de)浮銹也是(shi)危(wei)害(hai)(hai)性(xing)(xing)(xing)能品質(zhi)的(de)關鍵要(yao)素。
２）高(gao)壓膠(jiao)(jiao)管(guan)關鍵借(jie)助提(ti)高(gao)層(ceng)來承(cheng)(cheng)受(shou)力(li)(li)。手(shou)工(gong)編織橡膠(jiao)(jiao)軟管(guan)是(shi)靠膠(jiao)(jiao)漿(jiang)與內(nei)外黏(nian)膠(jiao)(jiao)粘緊，因(yin)為(wei)同(tong)一手(shou)工(gong)編織層(ceng)內(nei)不(bu)(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)(zhong)間(jian)的互相觸碰，在(zai)承(cheng)(cheng)擔(dan)氣(qi)體壓力(li)(li)的時候會因(yin)分別伸(shen)縮式不(bu)(bu)(bu)一而(er)導致不(bu)(bu)(bu)銹(xiu)鋼(gang)絲彼此之間(jian)的摩擦而(er)危害其使用性能(neng)。而(er)螺旋波紋管(guan)是(shi)由盤繞方位不(bu)(bu)(bu)一樣的雙層(ceng)產生(sheng)一個工(gong)作中(zhong)(zhong)(zhong)層(ceng)，在(zai)雙層(ceng)中(zhong)(zhong)(zhong)間(jian)有正中(zhong)(zhong)(zhong)間(jian)膠(jiao)(jiao)，因(yin)而(er)同(tong)一工(gong)作中(zhong)(zhong)(zhong)層(ceng)的雙層(ceng)不(bu)(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)(zhong)間(jian)沒有交(jiao)接點。因(yin)此 不(bu)(bu)(bu)容易(yi)在(zai)承(cheng)(cheng)擔(dan)氣(qi)體壓力(li)(li)時同(tong)于不(bu)(bu)(bu)銹(xiu)鋼(gang)絲間(jian)的交(jiao)叉(cha)式彎折而(er)產生(sheng)應力(li)(li)或磨(mo)(mo)擦磨(mo)(mo)壞。故使用性能(neng)好，能(neng)承(cheng)(cheng)擔(dan)髙壓。
３）高壓膠(jiao)管的外膠(jiao)層粘在提高層上起維護功效(xiao)，一般選(xuan)用氯丁膠(jiao)。應留意避免 其脆化開裂而危害全部橡(xiang)膠(jiao)軟管的使用壽命。
