１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)由(you)內(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)、提(ti)高(gao)層(ceng)和外膠(jiao)(jiao)(jiao)層(ceng)構成（如圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)立(li)即與(yu)液(ye)(ye)壓(ya)(ya)油觸(chu)碰，故規定在長期(qi)性(xing)運(yun)行狀態下不可受液(ye)(ye)體(ti)浸(jin)蝕(shi)，能補漏。在提(ti)高(gao)層(ceng)功(gong)效下會(hui)(hui)承擔一(yi)(yi)定工作壓(ya)(ya)力。因而，宜選用(yong)丁腈橡(xiang)膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外，危(wei)害(hai)性(xing)能的(de)(de)關鍵(jian)要(yao)素也(ye)(ye)有(you)內(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)的(de)(de)強度(du)、薄(bo)厚(hou)和永(yong)(yong)久(jiu)性(xing)形(xing)變(bian)量。強度(du)和永(yong)(yong)久(jiu)性(xing)形(xing)變(bian)量對密封性(xing)性(xing)能危(wei)害(hai)非(fei)常大。一(yi)(yi)般(ban)強度(du)高(gao)、縮(suo)小(xiao)后的(de)(de)永(yong)(yong)久(jiu)性(xing)形(xing)變(bian)量小(xiao)，密封性(xing)性(xing)能則越好(hao)。一(yi)(yi)般(ban)是(shi)在７０～８５邵氏硬度(du)，縮(suo)小(xiao)永(yong)(yong)久(jiu)性(xing)形(xing)變(bian)５０％時(shi)。內(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)薄(bo)厚(hou)建議(yi)是(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)會(hui)(hui)在壓(ya)(ya)扣時(shi)提(ti)升其(qi)流動率，導(dao)致不必(bi)要(yao)的(de)(de)膠(jiao)(jiao)(jiao)在接頭(tou)芯套與(yu)橡(xiang)膠(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸(chu)碰內(nei)(nei)孔(kong)內(nei)(nei)沉積(ji)，減(jian)少商品流通橫(heng)截面(mian)(mian)；過(guo)薄(bo)會(hui)(hui)在壓(ya)(ya)扣時(shi)被壓(ya)(ya)裂(lie)(lie)。另(ling)外內(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)壁厚(hou)勻稱性(xing)也(ye)(ye)很重(zhong)要(yao)。假如薄(bo)厚(hou)不勻，縮(suo)小(xiao)后會(hui)(hui)導(dao)致一(yi)(yi)面(mian)(mian)裂(lie)(lie)斷、一(yi)(yi)面(mian)(mian)堆(dui)膠(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)層(ceng)表層(ceng)出現的(de)(de)浮銹也(ye)(ye)是(shi)危(wei)害(hai)性(xing)能品質的(de)(de)關鍵(jian)要(yao)素。
２）高壓(ya)膠(jiao)(jiao)管(guan)關鍵借助(zhu)提高層(ceng)(ceng)來(lai)承(cheng)受力。手工(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)為(wei)同(tong)一(yi)手工(gong)編(bian)織層(ceng)(ceng)內不銹鋼絲(si)(si)(si)中(zhong)(zhong)間(jian)的(de)互(hu)相觸碰(peng)，在(zai)承(cheng)擔(dan)氣體壓(ya)力的(de)時候(hou)會因(yin)分別(bie)伸縮式不一(yi)而導致不銹鋼絲(si)(si)(si)彼(bi)此之(zhi)間(jian)的(de)摩擦(ca)而危害其使(shi)用性能。而螺旋波紋管(guan)是由(you)盤繞方位不一(yi)樣(yang)的(de)雙層(ceng)(ceng)產生一(yi)個工(gong)作(zuo)中(zhong)(zhong)層(ceng)(ceng)，在(zai)雙層(ceng)(ceng)中(zhong)(zhong)間(jian)有(you)正中(zhong)(zhong)間(jian)膠(jiao)(jiao)，因(yin)而同(tong)一(yi)工(gong)作(zuo)中(zhong)(zhong)層(ceng)(ceng)的(de)雙層(ceng)(ceng)不銹鋼絲(si)(si)(si)中(zhong)(zhong)間(jian)沒有(you)交(jiao)接(jie)點。因(yin)此 不容易在(zai)承(cheng)擔(dan)氣體壓(ya)力時同(tong)于不銹鋼絲(si)(si)(si)間(jian)的(de)交(jiao)叉(cha)式彎折而產生應力或(huo)磨擦(ca)磨壞。故使(shi)用性能好，能承(cheng)擔(dan)髙壓(ya)。
３）高(gao)壓膠(jiao)(jiao)管(guan)的外膠(jiao)(jiao)層(ceng)(ceng)粘在(zai)提(ti)高(gao)層(ceng)(ceng)上起維(wei)護功效，一(yi)般選用氯丁(ding)膠(jiao)(jiao)。應(ying)留意避免(mian) 其脆化(hua)開裂(lie)而危害全部橡膠(jiao)(jiao)軟管(guan)的使用壽命。
