１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)管由內(nei)膠(jiao)層(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)和(he)外膠(jiao)層(ceng)(ceng)(ceng)構成(cheng)（如(ru)圖例），內(nei)膠(jiao)層(ceng)(ceng)(ceng)立(li)即與(yu)液(ye)壓(ya)油觸(chu)碰，故規定(ding)在長期性(xing)(xing)(xing)(xing)(xing)運(yun)行(xing)狀態下不(bu)可受液(ye)體(ti)浸蝕，能(neng)補漏。在提高(gao)層(ceng)(ceng)(ceng)功效下會(hui)承擔一定(ding)工作壓(ya)力。因而，宜選用丁腈橡膠(jiao)，除塑膠(jiao)粒外，危害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)的(de)關鍵(jian)(jian)要素也有內(nei)膠(jiao)層(ceng)(ceng)(ceng)的(de)強(qiang)(qiang)度、薄(bo)(bo)厚(hou)和(he)永(yong)(yong)久性(xing)(xing)(xing)(xing)(xing)形變(bian)量(liang)(liang)。強(qiang)(qiang)度和(he)永(yong)(yong)久性(xing)(xing)(xing)(xing)(xing)形變(bian)量(liang)(liang)對密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)危害(hai)非常大。一般強(qiang)(qiang)度高(gao)、縮(suo)小(xiao)后的(de)永(yong)(yong)久性(xing)(xing)(xing)(xing)(xing)形變(bian)量(liang)(liang)小(xiao)，密封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)則(ze)越好。一般是(shi)在７０～８５邵氏(shi)硬度，縮(suo)小(xiao)永(yong)(yong)久性(xing)(xing)(xing)(xing)(xing)形變(bian)５０％時(shi)。內(nei)膠(jiao)層(ceng)(ceng)(ceng)薄(bo)(bo)厚(hou)建議是(shi)為(wei)１．５～２．５ｍｍ，太(tai)厚(hou)會(hui)在壓(ya)扣時(shi)提升(sheng)其(qi)流(liu)動率，導(dao)致不(bu)必要的(de)膠(jiao)在接頭芯套與(yu)橡膠(jiao)軟管的(de)觸(chu)碰內(nei)孔內(nei)沉(chen)積，減(jian)少商(shang)品(pin)流(liu)通(tong)橫截面；過(guo)薄(bo)(bo)會(hui)在壓(ya)扣時(shi)被(bei)壓(ya)裂。另(ling)外內(nei)膠(jiao)層(ceng)(ceng)(ceng)壁(bi)厚(hou)勻稱(cheng)性(xing)(xing)(xing)(xing)(xing)也很重要。假(jia)如(ru)薄(bo)(bo)厚(hou)不(bu)勻，縮(suo)小(xiao)后會(hui)導(dao)致一面裂斷(duan)、一面堆(dui)膠(jiao)。內(nei)膠(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)浮銹(xiu)也是(shi)危害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)品(pin)質的(de)關鍵(jian)(jian)要素。
２）高壓(ya)膠(jiao)(jiao)管關(guan)鍵借(jie)助提高層(ceng)來承(cheng)受力(li)。手工編(bian)織(zhi)橡膠(jiao)(jiao)軟管是(shi)靠膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊，因(yin)(yin)為同一(yi)手工編(bian)織(zhi)層(ceng)內不(bu)銹(xiu)鋼(gang)絲(si)中(zhong)間(jian)的(de)(de)互(hu)相觸碰，在承(cheng)擔(dan)(dan)氣體(ti)壓(ya)力(li)的(de)(de)時候會因(yin)(yin)分(fen)別伸縮式不(bu)一(yi)而(er)導(dao)致(zhi)不(bu)銹(xiu)鋼(gang)絲(si)彼此之間(jian)的(de)(de)摩擦(ca)而(er)危(wei)害其使用(yong)性能(neng)(neng)。而(er)螺旋波紋管是(shi)由盤繞方位不(bu)一(yi)樣(yang)的(de)(de)雙(shuang)層(ceng)產(chan)(chan)生(sheng)一(yi)個工作中(zhong)層(ceng)，在雙(shuang)層(ceng)中(zhong)間(jian)有正(zheng)中(zhong)間(jian)膠(jiao)(jiao)，因(yin)(yin)而(er)同一(yi)工作中(zhong)層(ceng)的(de)(de)雙(shuang)層(ceng)不(bu)銹(xiu)鋼(gang)絲(si)中(zhong)間(jian)沒(mei)有交接點。因(yin)(yin)此 不(bu)容易在承(cheng)擔(dan)(dan)氣體(ti)壓(ya)力(li)時同于不(bu)銹(xiu)鋼(gang)絲(si)間(jian)的(de)(de)交叉式彎折而(er)產(chan)(chan)生(sheng)應力(li)或磨(mo)擦(ca)磨(mo)壞。故(gu)使用(yong)性能(neng)(neng)好(hao)，能(neng)(neng)承(cheng)擔(dan)(dan)髙壓(ya)。
３）高壓膠(jiao)管(guan)的外膠(jiao)層粘在提(ti)高層上起維(wei)護功效(xiao)，一般選用氯丁膠(jiao)。應留意避免(mian) 其脆化(hua)開(kai)裂(lie)而危害(hai)全部(bu)橡膠(jiao)軟(ruan)管(guan)的使用壽命(ming)。
