１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)、提高(gao)層(ceng)(ceng)和外膠(jiao)(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如圖例(li)），內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液壓(ya)油觸碰(peng)，故規定(ding)在(zai)(zai)(zai)(zai)長期性(xing)(xing)運行狀態下不可(ke)受液體浸蝕，能(neng)(neng)補漏。在(zai)(zai)(zai)(zai)提高(gao)層(ceng)(ceng)功效下會(hui)承(cheng)擔一(yi)(yi)(yi)定(ding)工(gong)作壓(ya)力。因而，宜(yi)選(xuan)用(yong)丁(ding)腈橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外，危(wei)害性(xing)(xing)能(neng)(neng)的關(guan)鍵要(yao)素(su)也(ye)有內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)的強(qiang)度(du)、薄(bo)厚和永(yong)久(jiu)(jiu)性(xing)(xing)形變(bian)量(liang)。強(qiang)度(du)和永(yong)久(jiu)(jiu)性(xing)(xing)形變(bian)量(liang)對密封性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害非常大。一(yi)(yi)(yi)般強(qiang)度(du)高(gao)、縮小后的永(yong)久(jiu)(jiu)性(xing)(xing)形變(bian)量(liang)小，密封性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好。一(yi)(yi)(yi)般是(shi)在(zai)(zai)(zai)(zai)７０～８５邵氏硬度(du)，縮小永(yong)久(jiu)(jiu)性(xing)(xing)形變(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚建(jian)議是(shi)為１．５～２．５ｍｍ，太厚會(hui)在(zai)(zai)(zai)(zai)壓(ya)扣時(shi)提升其(qi)流動率，導(dao)致(zhi)不必(bi)要(yao)的膠(jiao)(jiao)(jiao)在(zai)(zai)(zai)(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)軟管的觸碰(peng)內(nei)孔內(nei)沉積，減少(shao)商(shang)品(pin)流通橫截面(mian)；過(guo)薄(bo)會(hui)在(zai)(zai)(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂。另外內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚勻稱性(xing)(xing)也(ye)很重(zhong)要(yao)。假如薄(bo)厚不勻，縮小后會(hui)導(dao)致(zhi)一(yi)(yi)(yi)面(mian)裂斷、一(yi)(yi)(yi)面(mian)堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出(chu)現(xian)的浮銹也(ye)是(shi)危(wei)害性(xing)(xing)能(neng)(neng)品(pin)質的關(guan)鍵要(yao)素(su)。
２）高(gao)壓(ya)膠(jiao)管關鍵借助提(ti)高(gao)層(ceng)來承受力。手(shou)工(gong)編織(zhi)橡膠(jiao)軟管是靠膠(jiao)漿與內外黏膠(jiao)粘緊，因為(wei)同一手(shou)工(gong)編織(zhi)層(ceng)內不(bu)(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)中(zhong)(zhong)(zhong)間的(de)(de)互相觸(chu)碰，在承擔(dan)氣體壓(ya)力的(de)(de)時(shi)候會(hui)因分別伸縮(suo)式不(bu)(bu)(bu)(bu)(bu)一而導致不(bu)(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)彼此之間的(de)(de)摩(mo)擦(ca)而危(wei)害(hai)其使用性能(neng)。而螺旋(xuan)波紋(wen)管是由盤繞方位(wei)不(bu)(bu)(bu)(bu)(bu)一樣的(de)(de)雙層(ceng)產(chan)生(sheng)一個工(gong)作(zuo)中(zhong)(zhong)(zhong)層(ceng)，在雙層(ceng)中(zhong)(zhong)(zhong)間有(you)正中(zhong)(zhong)(zhong)間膠(jiao)，因而同一工(gong)作(zuo)中(zhong)(zhong)(zhong)層(ceng)的(de)(de)雙層(ceng)不(bu)(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)中(zhong)(zhong)(zhong)間沒有(you)交接點。因此 不(bu)(bu)(bu)(bu)(bu)容易(yi)在承擔(dan)氣體壓(ya)力時(shi)同于不(bu)(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)間的(de)(de)交叉式彎(wan)折而產(chan)生(sheng)應力或磨擦(ca)磨壞。故使用性能(neng)好，能(neng)承擔(dan)髙壓(ya)。
３）高壓膠管的外膠層粘在提高層上起維護功效，一般選用氯丁膠。應留意避免 其脆化開裂(lie)而危害全部橡膠軟管的使用壽命(ming)。
