１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)管(guan)由內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如圖(tu)例），內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即與(yu)液(ye)壓(ya)油(you)觸碰，故規定在(zai)長期性運行狀態下(xia)不(bu)可(ke)受液(ye)體浸蝕，能補漏。在(zai)提高(gao)層(ceng)(ceng)(ceng)(ceng)功效下(xia)會(hui)承擔一(yi)(yi)(yi)定工(gong)作壓(ya)力。因而，宜選用丁(ding)腈橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外(wai)，危(wei)害性能的關鍵要(yao)素也(ye)有(you)內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的強度、薄(bo)(bo)(bo)厚(hou)(hou)和永(yong)久性形變(bian)量(liang)(liang)(liang)。強度和永(yong)久性形變(bian)量(liang)(liang)(liang)對密(mi)封性性能危(wei)害非(fei)常大。一(yi)(yi)(yi)般強度高(gao)、縮小后的永(yong)久性形變(bian)量(liang)(liang)(liang)小，密(mi)封性性能則(ze)越(yue)好。一(yi)(yi)(yi)般是在(zai)７０～８５邵氏(shi)硬(ying)度，縮小永(yong)久性形變(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄(bo)(bo)(bo)厚(hou)(hou)建(jian)議是為(wei)１．５～２．５ｍｍ，太(tai)厚(hou)(hou)會(hui)在(zai)壓(ya)扣時(shi)提升其流(liu)動率，導(dao)致不(bu)必要(yao)的膠(jiao)(jiao)(jiao)在(zai)接頭芯(xin)套與(yu)橡膠(jiao)(jiao)(jiao)軟管(guan)的觸碰內(nei)孔內(nei)沉積，減少商品流(liu)通橫截面；過薄(bo)(bo)(bo)會(hui)在(zai)壓(ya)扣時(shi)被(bei)壓(ya)裂。另外(wai)內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚(hou)(hou)勻稱性也(ye)很重(zhong)要(yao)。假如薄(bo)(bo)(bo)厚(hou)(hou)不(bu)勻，縮小后會(hui)導(dao)致一(yi)(yi)(yi)面裂斷(duan)、一(yi)(yi)(yi)面堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出(chu)現的浮(fu)銹也(ye)是危(wei)害性能品質的關鍵要(yao)素。
２）高(gao)壓(ya)膠(jiao)管關(guan)鍵借助提高(gao)層(ceng)(ceng)來承(cheng)(cheng)受力(li)。手工(gong)編(bian)織橡膠(jiao)軟(ruan)管是(shi)靠(kao)膠(jiao)漿(jiang)與內(nei)外黏膠(jiao)粘緊(jin)，因(yin)為(wei)同(tong)一(yi)手工(gong)編(bian)織層(ceng)(ceng)內(nei)不(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)絲中間(jian)(jian)(jian)的(de)互相觸碰，在(zai)承(cheng)(cheng)擔(dan)氣體壓(ya)力(li)的(de)時候會因(yin)分別伸縮式(shi)不(bu)(bu)(bu)一(yi)而(er)導致不(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)絲彼此之(zhi)間(jian)(jian)(jian)的(de)摩擦而(er)危害其(qi)使用性能。而(er)螺旋(xuan)波紋管是(shi)由盤繞(rao)方位(wei)不(bu)(bu)(bu)一(yi)樣的(de)雙層(ceng)(ceng)產(chan)(chan)生(sheng)一(yi)個(ge)工(gong)作中層(ceng)(ceng)，在(zai)雙層(ceng)(ceng)中間(jian)(jian)(jian)有正中間(jian)(jian)(jian)膠(jiao)，因(yin)而(er)同(tong)一(yi)工(gong)作中層(ceng)(ceng)的(de)雙層(ceng)(ceng)不(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)絲中間(jian)(jian)(jian)沒有交接點。因(yin)此 不(bu)(bu)(bu)容易在(zai)承(cheng)(cheng)擔(dan)氣體壓(ya)力(li)時同(tong)于不(bu)(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)絲間(jian)(jian)(jian)的(de)交叉(cha)式(shi)彎折而(er)產(chan)(chan)生(sheng)應(ying)力(li)或磨擦磨壞。故使用性能好，能承(cheng)(cheng)擔(dan)髙壓(ya)。
３）高壓(ya)膠管的外膠層(ceng)粘在(zai)提高層(ceng)上起(qi)維護功(gong)效，一般選用(yong)氯丁膠。應留意避免 其脆化(hua)開裂而危害全部橡膠軟管的使(shi)用(yong)壽命。
