１、橡膠軟管總成
1）高壓(ya)膠管由內(nei)膠層、提高層和(he)外(wai)膠層構(gou)成（如圖例(li)），內(nei)膠層立(li)即與液壓(ya)油(you)觸碰，故規(gui)定在(zai)(zai)長期(qi)性(xing)運行狀態下不可受液體浸蝕，能(neng)補漏。在(zai)(zai)提高層功效(xiao)下會(hui)承(cheng)擔(dan)一定工(gong)作壓(ya)力。因而，宜選用丁腈橡膠，除塑膠粒外(wai)，危(wei)害(hai)性(xing)能(neng)的(de)關鍵(jian)要(yao)素也有內(nei)膠層的(de)強(qiang)度(du)、薄(bo)厚和(he)永(yong)久性(xing)形(xing)(xing)變(bian)量(liang)。強(qiang)度(du)和(he)永(yong)久性(xing)形(xing)(xing)變(bian)量(liang)對密封(feng)(feng)性(xing)性(xing)能(neng)危(wei)害(hai)非(fei)常大。一般強(qiang)度(du)高、縮小(xiao)(xiao)(xiao)后的(de)永(yong)久性(xing)形(xing)(xing)變(bian)量(liang)小(xiao)(xiao)(xiao)，密封(feng)(feng)性(xing)性(xing)能(neng)則(ze)越好。一般是(shi)(shi)在(zai)(zai)７０～８５邵氏硬度(du)，縮小(xiao)(xiao)(xiao)永(yong)久性(xing)形(xing)(xing)變(bian)５０％時(shi)(shi)。內(nei)膠層薄(bo)厚建議是(shi)(shi)為１．５～２．５ｍｍ，太厚會(hui)在(zai)(zai)壓(ya)扣(kou)時(shi)(shi)提升其(qi)流動(dong)率，導致不必要(yao)的(de)膠在(zai)(zai)接頭芯套與橡膠軟管的(de)觸碰內(nei)孔內(nei)沉積(ji)，減少商品流通橫截面(mian)；過(guo)薄(bo)會(hui)在(zai)(zai)壓(ya)扣(kou)時(shi)(shi)被壓(ya)裂。另外(wai)內(nei)膠層壁厚勻稱(cheng)性(xing)也很(hen)重要(yao)。假(jia)如薄(bo)厚不勻，縮小(xiao)(xiao)(xiao)后會(hui)導致一面(mian)裂斷(duan)、一面(mian)堆(dui)膠。內(nei)膠層表層出(chu)現的(de)浮銹也是(shi)(shi)危(wei)害(hai)性(xing)能(neng)品質的(de)關鍵(jian)要(yao)素。
２）高壓(ya)膠(jiao)(jiao)管(guan)關鍵借助提高層(ceng)(ceng)來承(cheng)(cheng)受(shou)力。手(shou)工(gong)編(bian)織橡膠(jiao)(jiao)軟管(guan)是靠膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊，因(yin)(yin)為同(tong)一手(shou)工(gong)編(bian)織層(ceng)(ceng)內不(bu)(bu)銹(xiu)(xiu)鋼絲(si)中(zhong)間(jian)(jian)(jian)的(de)(de)互相觸(chu)碰(peng)，在承(cheng)(cheng)擔(dan)氣體(ti)(ti)壓(ya)力的(de)(de)時候會因(yin)(yin)分別伸縮式(shi)不(bu)(bu)一而(er)(er)導致(zhi)不(bu)(bu)銹(xiu)(xiu)鋼絲(si)彼(bi)此之間(jian)(jian)(jian)的(de)(de)摩(mo)擦而(er)(er)危(wei)害其使(shi)用性(xing)能(neng)(neng)。而(er)(er)螺(luo)旋波紋管(guan)是由盤繞方位(wei)不(bu)(bu)一樣的(de)(de)雙層(ceng)(ceng)產生一個工(gong)作中(zhong)層(ceng)(ceng)，在雙層(ceng)(ceng)中(zhong)間(jian)(jian)(jian)有(you)正(zheng)中(zhong)間(jian)(jian)(jian)膠(jiao)(jiao)，因(yin)(yin)而(er)(er)同(tong)一工(gong)作中(zhong)層(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)不(bu)(bu)銹(xiu)(xiu)鋼絲(si)中(zhong)間(jian)(jian)(jian)沒有(you)交接(jie)點。因(yin)(yin)此 不(bu)(bu)容易(yi)在承(cheng)(cheng)擔(dan)氣體(ti)(ti)壓(ya)力時同(tong)于不(bu)(bu)銹(xiu)(xiu)鋼絲(si)間(jian)(jian)(jian)的(de)(de)交叉式(shi)彎折而(er)(er)產生應力或磨(mo)擦磨(mo)壞(huai)。故使(shi)用性(xing)能(neng)(neng)好，能(neng)(neng)承(cheng)(cheng)擔(dan)髙壓(ya)。
３）高(gao)壓(ya)膠管的外膠層粘(zhan)在提高(gao)層上起(qi)維護功(gong)效，一般選用氯丁膠。應留意(yi)避(bi)免 其脆(cui)化開裂而危害全部橡膠軟(ruan)管的使(shi)用壽命(ming)。
