１、橡膠軟管總成
1）高壓(ya)膠(jiao)管由內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)和(he)外(wai)膠(jiao)層(ceng)(ceng)(ceng)構(gou)成(cheng)（如圖例），內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)立即與(yu)液壓(ya)油觸碰，故規定(ding)(ding)在(zai)(zai)長期性(xing)(xing)(xing)(xing)運行(xing)狀(zhuang)態(tai)下不可受液體浸蝕，能(neng)(neng)(neng)補漏。在(zai)(zai)提(ti)高層(ceng)(ceng)(ceng)功效下會承擔一(yi)定(ding)(ding)工作壓(ya)力(li)。因而，宜選用丁(ding)腈橡膠(jiao)，除塑膠(jiao)粒外(wai)，危(wei)(wei)(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)的(de)(de)(de)關鍵(jian)要(yao)素(su)(su)也(ye)有內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)的(de)(de)(de)強(qiang)(qiang)(qiang)度、薄(bo)厚(hou)(hou)和(he)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)變量(liang)(liang)。強(qiang)(qiang)(qiang)度和(he)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)變量(liang)(liang)對(dui)密(mi)封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)危(wei)(wei)(wei)害(hai)非常(chang)大。一(yi)般強(qiang)(qiang)(qiang)度高、縮(suo)(suo)小(xiao)后的(de)(de)(de)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)變量(liang)(liang)小(xiao)，密(mi)封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)則越好(hao)。一(yi)般是(shi)在(zai)(zai)７０～８５邵(shao)氏硬(ying)度，縮(suo)(suo)小(xiao)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)變５０％時。內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)薄(bo)厚(hou)(hou)建(jian)議是(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)(hou)會在(zai)(zai)壓(ya)扣時提(ti)升其流動(dong)率，導(dao)(dao)致不必要(yao)的(de)(de)(de)膠(jiao)在(zai)(zai)接(jie)頭芯(xin)套與(yu)橡膠(jiao)軟管的(de)(de)(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積，減少商品流通(tong)橫截面(mian)；過薄(bo)會在(zai)(zai)壓(ya)扣時被(bei)壓(ya)裂(lie)。另外(wai)內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)壁(bi)厚(hou)(hou)勻(yun)稱(cheng)性(xing)(xing)(xing)(xing)也(ye)很重要(yao)。假如薄(bo)厚(hou)(hou)不勻(yun)，縮(suo)(suo)小(xiao)后會導(dao)(dao)致一(yi)面(mian)裂(lie)斷、一(yi)面(mian)堆膠(jiao)。內(nei)(nei)膠(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現(xian)的(de)(de)(de)浮(fu)銹也(ye)是(shi)危(wei)(wei)(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)品質的(de)(de)(de)關鍵(jian)要(yao)素(su)(su)。
２）高(gao)壓(ya)膠(jiao)(jiao)管(guan)關鍵借(jie)助提高(gao)層來承受力(li)。手工(gong)(gong)編(bian)織橡(xiang)膠(jiao)(jiao)軟管(guan)是(shi)靠膠(jiao)(jiao)漿與內(nei)外(wai)黏(nian)膠(jiao)(jiao)粘(zhan)緊(jin)，因(yin)為(wei)同一(yi)(yi)手工(gong)(gong)編(bian)織層內(nei)不(bu)銹(xiu)鋼絲(si)(si)中(zhong)(zhong)(zhong)(zhong)間(jian)的(de)互相觸(chu)碰，在承擔氣體壓(ya)力(li)的(de)時(shi)候會因(yin)分別伸縮(suo)式不(bu)一(yi)(yi)而(er)導致不(bu)銹(xiu)鋼絲(si)(si)彼(bi)此之間(jian)的(de)摩擦(ca)而(er)危害其使用性能(neng)。而(er)螺(luo)旋波紋(wen)管(guan)是(shi)由盤(pan)繞方位不(bu)一(yi)(yi)樣的(de)雙(shuang)層產(chan)生一(yi)(yi)個工(gong)(gong)作中(zhong)(zhong)(zhong)(zhong)層，在雙(shuang)層中(zhong)(zhong)(zhong)(zhong)間(jian)有(you)正(zheng)中(zhong)(zhong)(zhong)(zhong)間(jian)膠(jiao)(jiao)，因(yin)而(er)同一(yi)(yi)工(gong)(gong)作中(zhong)(zhong)(zhong)(zhong)層的(de)雙(shuang)層不(bu)銹(xiu)鋼絲(si)(si)中(zhong)(zhong)(zhong)(zhong)間(jian)沒有(you)交(jiao)接點。因(yin)此 不(bu)容易在承擔氣體壓(ya)力(li)時(shi)同于(yu)不(bu)銹(xiu)鋼絲(si)(si)間(jian)的(de)交(jiao)叉式彎折而(er)產(chan)生應力(li)或磨擦(ca)磨壞(huai)。故(gu)使用性能(neng)好，能(neng)承擔髙(gao)壓(ya)。
３）高壓膠(jiao)管的外膠(jiao)層粘在提高層上起維護功(gong)效，一般選(xuan)用(yong)氯丁膠(jiao)。應留意避(bi)免(mian) 其脆化開裂而危害全部橡(xiang)膠(jiao)軟管的使用(yong)壽命。
