１、橡膠軟管總成
1）高(gao)(gao)(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)由內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)、提高(gao)(gao)(gao)層(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)構成（如圖例），內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即(ji)與液壓(ya)(ya)油觸碰，故規定在(zai)(zai)長期性(xing)(xing)(xing)運行狀態下(xia)不(bu)可受(shou)液體浸蝕，能(neng)補漏。在(zai)(zai)提高(gao)(gao)(gao)層(ceng)(ceng)功效下(xia)會(hui)(hui)承擔一(yi)定工作壓(ya)(ya)力。因(yin)而，宜選(xuan)用丁腈(jing)橡(xiang)膠(jiao)(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)(jiao)粒外(wai)，危(wei)害(hai)性(xing)(xing)(xing)能(neng)的(de)關鍵(jian)要(yao)素也(ye)有(you)內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)強度、薄(bo)厚(hou)和永(yong)久(jiu)性(xing)(xing)(xing)形變量(liang)(liang)。強度和永(yong)久(jiu)性(xing)(xing)(xing)形變量(liang)(liang)對密(mi)封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危(wei)害(hai)非(fei)常大。一(yi)般(ban)強度高(gao)(gao)(gao)、縮(suo)小(xiao)后的(de)永(yong)久(jiu)性(xing)(xing)(xing)形變量(liang)(liang)小(xiao)，密(mi)封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好。一(yi)般(ban)是在(zai)(zai)７０～８５邵氏(shi)硬(ying)度，縮(suo)小(xiao)永(yong)久(jiu)性(xing)(xing)(xing)形變５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)建(jian)議是為(wei)１．５～２．５ｍｍ，太厚(hou)會(hui)(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)提升其流動率(lv)，導(dao)致不(bu)必要(yao)的(de)膠(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套與橡(xiang)膠(jiao)(jiao)(jiao)軟管(guan)的(de)觸碰內(nei)孔內(nei)沉(chen)積，減少商(shang)品流通橫截面(mian)(mian)；過薄(bo)會(hui)(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)被(bei)壓(ya)(ya)裂(lie)。另外(wai)內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)也(ye)很重要(yao)。假如薄(bo)厚(hou)不(bu)勻，縮(suo)小(xiao)后會(hui)(hui)導(dao)致一(yi)面(mian)(mian)裂(lie)斷、一(yi)面(mian)(mian)堆(dui)膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現(xian)的(de)浮銹(xiu)也(ye)是危(wei)害(hai)性(xing)(xing)(xing)能(neng)品質的(de)關鍵(jian)要(yao)素。
２）高壓(ya)膠管(guan)關鍵(jian)借助提高層(ceng)來承(cheng)(cheng)(cheng)受力。手(shou)工(gong)(gong)(gong)編(bian)織橡膠軟管(guan)是(shi)靠膠漿與內外黏膠粘緊，因(yin)為同(tong)(tong)一(yi)手(shou)工(gong)(gong)(gong)編(bian)織層(ceng)內不(bu)銹(xiu)鋼(gang)絲中間(jian)(jian)的(de)(de)互(hu)相觸(chu)碰，在承(cheng)(cheng)(cheng)擔(dan)氣體(ti)壓(ya)力的(de)(de)時(shi)候(hou)會因(yin)分別(bie)伸縮(suo)式不(bu)一(yi)而導致不(bu)銹(xiu)鋼(gang)絲彼此之間(jian)(jian)的(de)(de)摩擦(ca)而危害其使用性能。而螺旋波紋(wen)管(guan)是(shi)由盤繞方位不(bu)一(yi)樣(yang)的(de)(de)雙層(ceng)產生一(yi)個工(gong)(gong)(gong)作中層(ceng)，在雙層(ceng)中間(jian)(jian)有(you)正(zheng)中間(jian)(jian)膠，因(yin)而同(tong)(tong)一(yi)工(gong)(gong)(gong)作中層(ceng)的(de)(de)雙層(ceng)不(bu)銹(xiu)鋼(gang)絲中間(jian)(jian)沒有(you)交(jiao)接點。因(yin)此 不(bu)容易(yi)在承(cheng)(cheng)(cheng)擔(dan)氣體(ti)壓(ya)力時(shi)同(tong)(tong)于不(bu)銹(xiu)鋼(gang)絲間(jian)(jian)的(de)(de)交(jiao)叉式彎折(zhe)而產生應力或磨(mo)(mo)擦(ca)磨(mo)(mo)壞。故使用性能好，能承(cheng)(cheng)(cheng)擔(dan)髙壓(ya)。
３）高(gao)壓(ya)膠(jiao)(jiao)管的外(wai)膠(jiao)(jiao)層粘(zhan)在提高(gao)層上起維護(hu)功效(xiao)，一般選用(yong)氯丁膠(jiao)(jiao)。應留意避(bi)免 其脆化開(kai)裂而(er)危害全部橡膠(jiao)(jiao)軟管的使用(yong)壽(shou)命。
