１、橡膠軟管總成
1）高壓(ya)(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由(you)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高層(ceng)(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即(ji)與(yu)液壓(ya)(ya)(ya)油觸碰，故規定(ding)在長期性(xing)(xing)(xing)(xing)運行狀態下不(bu)(bu)可受液體浸蝕，能補漏。在提高層(ceng)(ceng)(ceng)功效下會承擔一(yi)定(ding)工作壓(ya)(ya)(ya)力。因而，宜選用丁(ding)腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒外(wai)，危害(hai)性(xing)(xing)(xing)(xing)能的(de)關鍵(jian)要素也(ye)有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強(qiang)(qiang)度(du)(du)、薄(bo)厚和永(yong)久(jiu)性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)。強(qiang)(qiang)度(du)(du)和永(yong)久(jiu)性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)對密(mi)封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能危害(hai)非常大。一(yi)般強(qiang)(qiang)度(du)(du)高、縮小(xiao)(xiao)后的(de)永(yong)久(jiu)性(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)小(xiao)(xiao)，密(mi)封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能則越(yue)好。一(yi)般是(shi)在７０～８５邵氏硬度(du)(du)，縮小(xiao)(xiao)永(yong)久(jiu)性(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時(shi)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建議是(shi)為１．５～２．５ｍｍ，太厚會在壓(ya)(ya)(ya)扣時(shi)提升其(qi)流動(dong)率，導(dao)(dao)致不(bu)(bu)必要的(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在接頭芯套與(yu)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰內(nei)(nei)孔內(nei)(nei)沉(chen)積，減少商品(pin)流通橫截面；過薄(bo)會在壓(ya)(ya)(ya)扣時(shi)被壓(ya)(ya)(ya)裂。另外(wai)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻稱(cheng)性(xing)(xing)(xing)(xing)也(ye)很重(zhong)要。假如薄(bo)厚不(bu)(bu)勻，縮小(xiao)(xiao)后會導(dao)(dao)致一(yi)面裂斷(duan)、一(yi)面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)浮銹(xiu)也(ye)是(shi)危害(hai)性(xing)(xing)(xing)(xing)能品(pin)質(zhi)的(de)關鍵(jian)要素。
２）高(gao)壓膠管(guan)關鍵(jian)借助(zhu)提高(gao)層(ceng)(ceng)來承受力(li)(li)(li)。手工(gong)編織橡(xiang)膠軟管(guan)是(shi)靠膠漿與內(nei)外黏膠粘緊(jin)，因為(wei)同(tong)(tong)(tong)一手工(gong)編織層(ceng)(ceng)內(nei)不(bu)(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間(jian)的(de)互相觸(chu)碰，在承擔(dan)(dan)(dan)氣體壓力(li)(li)(li)的(de)時候會(hui)因分別(bie)伸縮式(shi)不(bu)(bu)一而(er)(er)導(dao)致不(bu)(bu)銹鋼(gang)絲(si)彼(bi)此之間(jian)的(de)摩擦(ca)(ca)而(er)(er)危害其(qi)使(shi)用性能。而(er)(er)螺旋波紋管(guan)是(shi)由盤繞方位不(bu)(bu)一樣的(de)雙(shuang)層(ceng)(ceng)產(chan)生一個(ge)工(gong)作中(zhong)(zhong)層(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)中(zhong)(zhong)間(jian)有正中(zhong)(zhong)間(jian)膠，因而(er)(er)同(tong)(tong)(tong)一工(gong)作中(zhong)(zhong)層(ceng)(ceng)的(de)雙(shuang)層(ceng)(ceng)不(bu)(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間(jian)沒(mei)有交(jiao)接點(dian)。因此 不(bu)(bu)容易在承擔(dan)(dan)(dan)氣體壓力(li)(li)(li)時同(tong)(tong)(tong)于(yu)不(bu)(bu)銹鋼(gang)絲(si)間(jian)的(de)交(jiao)叉(cha)式(shi)彎(wan)折而(er)(er)產(chan)生應力(li)(li)(li)或磨擦(ca)(ca)磨壞。故使(shi)用性能好，能承擔(dan)(dan)(dan)髙(gao)壓。
３）高壓膠(jiao)(jiao)管的(de)外膠(jiao)(jiao)層粘在提(ti)高層上起維護功效，一般選用(yong)氯(lv)丁膠(jiao)(jiao)。應(ying)留意(yi)避免 其脆化開裂而危(wei)害(hai)全部橡膠(jiao)(jiao)軟管的(de)使(shi)用(yong)壽命(ming)。
