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(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如(ru)圖例），內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即(ji)與液(ye)壓(ya)油(you)觸碰，故規定(ding)在(zai)長期性(xing)(xing)(xing)運(yun)行狀態下不可受液(ye)體浸蝕，能(neng)(neng)(neng)(neng)補漏(lou)。在(zai)提高(gao)層(ceng)(ceng)功(gong)效下會(hui)承擔一定(ding)工作壓(ya)力。因而(er)，宜選用丁腈橡膠(jiao)(jiao)(jiao)，除(chu)塑(su)膠(jiao)(jiao)(jiao)粒(li)外(wai)，危(wei)害(hai)性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)的(de)(de)(de)(de)關鍵(jian)要(yao)素也(ye)有內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)(de)(de)強(qiang)度(du)(du)、薄(bo)厚(hou)和永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量(liang)。強(qiang)度(du)(du)和永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量(liang)對(dui)密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)危(wei)害(hai)非常大。一般強(qiang)度(du)(du)高(gao)、縮(suo)小(xiao)(xiao)后(hou)的(de)(de)(de)(de)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量(liang)小(xiao)(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)則越好。一般是(shi)(shi)在(zai)７０～８５邵(shao)氏(shi)硬度(du)(du)，縮(suo)小(xiao)(xiao)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)建議是(shi)(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)會(hui)在(zai)壓(ya)扣時(shi)提升其流動率，導致不必(bi)要(yao)的(de)(de)(de)(de)膠(jiao)(jiao)(jiao)在(zai)接頭芯(xin)套與橡膠(jiao)(jiao)(jiao)軟管的(de)(de)(de)(de)觸碰內(nei)孔內(nei)沉積，減(jian)少商品流通橫截面；過薄(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)壁厚(hou)勻稱性(xing)(xing)(xing)也(ye)很重要(yao)。假(jia)如(ru)薄(bo)厚(hou)不勻，縮(suo)小(xiao)(xiao)后(hou)會(hui)導致一面裂斷、一面堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)(de)(de)浮銹也(ye)是(shi)(shi)危(wei)害(hai)性(xing)(xing)(xing)能(neng)(neng)(neng)(neng)品質的(de)(de)(de)(de)關鍵(jian)要(yao)素。
２）高(gao)壓膠(jiao)管關鍵借助提高(gao)層(ceng)(ceng)來承受力(li)(li)。手(shou)工(gong)(gong)編織橡膠(jiao)軟管是靠(kao)膠(jiao)漿與內外黏(nian)膠(jiao)粘緊(jin)，因為同(tong)一(yi)手(shou)工(gong)(gong)編織層(ceng)(ceng)內不(bu)銹鋼絲中(zhong)(zhong)(zhong)間(jian)(jian)的(de)(de)(de)(de)互(hu)相觸碰，在(zai)承擔(dan)氣體(ti)(ti)壓力(li)(li)的(de)(de)(de)(de)時(shi)候會因分別伸縮式(shi)不(bu)一(yi)而(er)導致不(bu)銹鋼絲彼此之(zhi)間(jian)(jian)的(de)(de)(de)(de)摩擦(ca)而(er)危害其使(shi)用(yong)性能(neng)。而(er)螺(luo)旋(xuan)波紋(wen)管是由盤(pan)繞方位不(bu)一(yi)樣的(de)(de)(de)(de)雙(shuang)層(ceng)(ceng)產生一(yi)個工(gong)(gong)作中(zhong)(zhong)(zhong)層(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)中(zhong)(zhong)(zhong)間(jian)(jian)有正(zheng)中(zhong)(zhong)(zhong)間(jian)(jian)膠(jiao)，因而(er)同(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)(zhong)層(ceng)(ceng)的(de)(de)(de)(de)雙(shuang)層(ceng)(ceng)不(bu)銹鋼絲中(zhong)(zhong)(zhong)間(jian)(jian)沒(mei)有交接(jie)點(dian)。因此 不(bu)容易在(zai)承擔(dan)氣體(ti)(ti)壓力(li)(li)時(shi)同(tong)于(yu)不(bu)銹鋼絲間(jian)(jian)的(de)(de)(de)(de)交叉式(shi)彎折而(er)產生應力(li)(li)或磨擦(ca)磨壞。故使(shi)用(yong)性能(neng)好(hao)，能(neng)承擔(dan)髙(gao)壓。
３）高(gao)壓膠(jiao)(jiao)管(guan)的外(wai)膠(jiao)(jiao)層(ceng)粘(zhan)在提高(gao)層(ceng)上(shang)起維護(hu)功效，一般選用氯丁(ding)膠(jiao)(jiao)。應留意(yi)避免 其脆(cui)化開裂而危害(hai)全部橡膠(jiao)(jiao)軟管(guan)的使(shi)用壽命(ming)。
