１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由(you)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)(ti)高層(ceng)(ceng)和外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如(ru)圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液壓(ya)油觸(chu)碰(peng)，故規定(ding)在(zai)(zai)長期性(xing)(xing)(xing)(xing)(xing)運行狀(zhuang)態下(xia)不(bu)可受(shou)液體浸蝕，能補漏(lou)。在(zai)(zai)提(ti)(ti)高層(ceng)(ceng)功效(xiao)下(xia)會(hui)(hui)承擔(dan)一定(ding)工作壓(ya)力(li)。因而，宜選用丁腈(jing)橡(xiang)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)(xing)能的(de)(de)關鍵要(yao)(yao)素也有(you)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度(du)、薄(bo)厚(hou)和永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)。強(qiang)度(du)和永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)對密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能危害非常大。一般強(qiang)度(du)高、縮小(xiao)(xiao)后的(de)(de)永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)小(xiao)(xiao)，密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能則(ze)越好。一般是在(zai)(zai)７０～８５邵氏硬度(du)，縮小(xiao)(xiao)永(yong)(yong)久(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)建議是為１．５～２．５ｍｍ，太厚(hou)會(hui)(hui)在(zai)(zai)壓(ya)扣時(shi)提(ti)(ti)升其流(liu)動(dong)率(lv)，導(dao)致不(bu)必要(yao)(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套(tao)與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)觸(chu)碰(peng)內(nei)孔內(nei)沉積，減(jian)少商品流(liu)通橫截面(mian)；過薄(bo)會(hui)(hui)在(zai)(zai)壓(ya)扣時(shi)被(bei)壓(ya)裂。另(ling)外(wai)(wai)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)(xing)(xing)也很(hen)重要(yao)(yao)。假如(ru)薄(bo)厚(hou)不(bu)勻，縮小(xiao)(xiao)后會(hui)(hui)導(dao)致一面(mian)裂斷、一面(mian)堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表(biao)層(ceng)(ceng)出(chu)現的(de)(de)浮銹也是危害性(xing)(xing)(xing)(xing)(xing)能品質的(de)(de)關鍵要(yao)(yao)素。
２）高壓(ya)膠(jiao)(jiao)管(guan)關鍵借助(zhu)提高層(ceng)來承(cheng)受(shou)力。手工編織橡膠(jiao)(jiao)軟管(guan)是靠(kao)膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊，因為(wei)同一(yi)手工編織層(ceng)內不(bu)銹鋼(gang)絲(si)中(zhong)間(jian)(jian)的互相觸碰，在(zai)(zai)承(cheng)擔(dan)氣體壓(ya)力的時候會因分別(bie)伸縮式不(bu)一(yi)而(er)導致不(bu)銹鋼(gang)絲(si)彼(bi)此(ci)之間(jian)(jian)的摩(mo)擦而(er)危(wei)害其使用性能。而(er)螺旋波紋管(guan)是由盤繞方位(wei)不(bu)一(yi)樣的雙層(ceng)產(chan)生一(yi)個(ge)工作(zuo)(zuo)中(zhong)層(ceng)，在(zai)(zai)雙層(ceng)中(zhong)間(jian)(jian)有(you)正中(zhong)間(jian)(jian)膠(jiao)(jiao)，因而(er)同一(yi)工作(zuo)(zuo)中(zhong)層(ceng)的雙層(ceng)不(bu)銹鋼(gang)絲(si)中(zhong)間(jian)(jian)沒有(you)交接點。因此(ci) 不(bu)容易在(zai)(zai)承(cheng)擔(dan)氣體壓(ya)力時同于(yu)不(bu)銹鋼(gang)絲(si)間(jian)(jian)的交叉式彎折而(er)產(chan)生應(ying)力或磨(mo)擦磨(mo)壞。故使用性能好，能承(cheng)擔(dan)髙壓(ya)。
３）高壓膠(jiao)管(guan)的(de)外膠(jiao)層(ceng)粘(zhan)在提(ti)高層(ceng)上起維護功效，一般選用氯丁膠(jiao)。應留意(yi)避免 其脆化開裂而危害(hai)全部橡膠(jiao)軟管(guan)的(de)使用壽命(ming)。
