１、橡膠軟管總成
1）高(gao)(gao)壓(ya)(ya)膠(jiao)管由內膠(jiao)層(ceng)、提(ti)高(gao)(gao)層(ceng)和外(wai)膠(jiao)層(ceng)構成（如(ru)圖(tu)例），內膠(jiao)層(ceng)立(li)即與液壓(ya)(ya)油觸(chu)碰(peng)，故(gu)規定(ding)在(zai)長(chang)期(qi)性(xing)(xing)運行狀(zhuang)態下不(bu)可(ke)受液體(ti)浸(jin)蝕，能(neng)(neng)補(bu)漏。在(zai)提(ti)高(gao)(gao)層(ceng)功效下會(hui)(hui)承擔(dan)一(yi)定(ding)工作(zuo)壓(ya)(ya)力。因而，宜(yi)選用(yong)丁腈(jing)橡(xiang)膠(jiao)，除塑膠(jiao)粒外(wai)，危(wei)害性(xing)(xing)能(neng)(neng)的(de)關鍵要素也(ye)有內膠(jiao)層(ceng)的(de)強(qiang)度(du)、薄(bo)厚和永(yong)久性(xing)(xing)形變量(liang)(liang)。強(qiang)度(du)和永(yong)久性(xing)(xing)形變量(liang)(liang)對密(mi)封性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害非常大。一(yi)般(ban)強(qiang)度(du)高(gao)(gao)、縮(suo)小(xiao)(xiao)后的(de)永(yong)久性(xing)(xing)形變量(liang)(liang)小(xiao)(xiao)，密(mi)封性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好。一(yi)般(ban)是在(zai)７０～８５邵氏硬(ying)度(du)，縮(suo)小(xiao)(xiao)永(yong)久性(xing)(xing)形變５０％時(shi)。內膠(jiao)層(ceng)薄(bo)厚建議(yi)是為(wei)１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)壓(ya)(ya)扣時(shi)提(ti)升其流動率，導(dao)致(zhi)不(bu)必(bi)要的(de)膠(jiao)在(zai)接(jie)頭芯套與橡(xiang)膠(jiao)軟(ruan)管的(de)觸(chu)碰(peng)內孔內沉積，減少商(shang)品流通橫(heng)截面(mian)；過(guo)薄(bo)會(hui)(hui)在(zai)壓(ya)(ya)扣時(shi)被壓(ya)(ya)裂。另(ling)外(wai)內膠(jiao)層(ceng)壁(bi)厚勻稱(cheng)性(xing)(xing)也(ye)很(hen)重要。假如(ru)薄(bo)厚不(bu)勻，縮(suo)小(xiao)(xiao)后會(hui)(hui)導(dao)致(zhi)一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)。內膠(jiao)層(ceng)表層(ceng)出現(xian)的(de)浮銹也(ye)是危(wei)害性(xing)(xing)能(neng)(neng)品質(zhi)的(de)關鍵要素。
２）高(gao)壓(ya)膠(jiao)(jiao)(jiao)管(guan)關(guan)鍵借助提高(gao)層(ceng)(ceng)(ceng)來承(cheng)(cheng)受力。手工(gong)編(bian)織(zhi)橡膠(jiao)(jiao)(jiao)軟管(guan)是靠膠(jiao)(jiao)(jiao)漿與內外(wai)黏(nian)膠(jiao)(jiao)(jiao)粘(zhan)緊，因(yin)為同(tong)一(yi)手工(gong)編(bian)織(zhi)層(ceng)(ceng)(ceng)內不(bu)(bu)(bu)(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)絲(si)中(zhong)間(jian)(jian)的(de)(de)(de)互相觸碰，在(zai)承(cheng)(cheng)擔(dan)(dan)氣體(ti)壓(ya)力的(de)(de)(de)時候會因(yin)分別伸(shen)縮式(shi)不(bu)(bu)(bu)(bu)(bu)(bu)一(yi)而導致不(bu)(bu)(bu)(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)絲(si)彼(bi)此之間(jian)(jian)的(de)(de)(de)摩擦而危害其使用(yong)性能。而螺旋波紋管(guan)是由盤繞方位不(bu)(bu)(bu)(bu)(bu)(bu)一(yi)樣的(de)(de)(de)雙層(ceng)(ceng)(ceng)產生一(yi)個工(gong)作中(zhong)層(ceng)(ceng)(ceng)，在(zai)雙層(ceng)(ceng)(ceng)中(zhong)間(jian)(jian)有(you)正(zheng)中(zhong)間(jian)(jian)膠(jiao)(jiao)(jiao)，因(yin)而同(tong)一(yi)工(gong)作中(zhong)層(ceng)(ceng)(ceng)的(de)(de)(de)雙層(ceng)(ceng)(ceng)不(bu)(bu)(bu)(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)絲(si)中(zhong)間(jian)(jian)沒(mei)有(you)交接點。因(yin)此 不(bu)(bu)(bu)(bu)(bu)(bu)容(rong)易在(zai)承(cheng)(cheng)擔(dan)(dan)氣體(ti)壓(ya)力時同(tong)于不(bu)(bu)(bu)(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)絲(si)間(jian)(jian)的(de)(de)(de)交叉(cha)式(shi)彎(wan)折而產生應力或磨擦磨壞。故使用(yong)性能好，能承(cheng)(cheng)擔(dan)(dan)髙壓(ya)。
３）高壓膠(jiao)管(guan)的(de)外膠(jiao)層(ceng)粘在提高層(ceng)上起維護功效，一般(ban)選用氯丁膠(jiao)。應(ying)留意(yi)避免(mian) 其(qi)脆化開裂而危害全部橡膠(jiao)軟管(guan)的(de)使用壽(shou)命。
