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、提(ti)高(gao)層和外(wai)(wai)膠(jiao)(jiao)(jiao)層構成（如圖(tu)例(li)），內(nei)膠(jiao)(jiao)(jiao)層立即與液(ye)(ye)壓(ya)油觸碰(peng)，故規(gui)定(ding)在(zai)(zai)長(chang)期性(xing)(xing)(xing)運行狀態下不可受液(ye)(ye)體(ti)浸蝕，能(neng)補漏。在(zai)(zai)提(ti)高(gao)層功效(xiao)下會(hui)承擔一(yi)定(ding)工作壓(ya)力。因而，宜選(xuan)用丁(ding)腈橡(xiang)膠(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)粒外(wai)(wai)，危害(hai)性(xing)(xing)(xing)能(neng)的關鍵(jian)要(yao)素也有內(nei)膠(jiao)(jiao)(jiao)層的強度(du)(du)、薄厚(hou)和永(yong)久性(xing)(xing)(xing)形(xing)(xing)變量。強度(du)(du)和永(yong)久性(xing)(xing)(xing)形(xing)(xing)變量對密(mi)封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害(hai)非常大。一(yi)般強度(du)(du)高(gao)、縮(suo)小(xiao)后(hou)的永(yong)久性(xing)(xing)(xing)形(xing)(xing)變量小(xiao)，密(mi)封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好。一(yi)般是(shi)在(zai)(zai)７０～８５邵氏硬度(du)(du)，縮(suo)小(xiao)永(yong)久性(xing)(xing)(xing)形(xing)(xing)變５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)層薄厚(hou)建議(yi)是(shi)為１．５～２．５ｍｍ，太厚(hou)會(hui)在(zai)(zai)壓(ya)扣時(shi)提(ti)升其流動率，導(dao)(dao)致(zhi)不必(bi)要(yao)的膠(jiao)(jiao)(jiao)在(zai)(zai)接頭芯(xin)套(tao)與橡(xiang)膠(jiao)(jiao)(jiao)軟管的觸碰(peng)內(nei)孔內(nei)沉積，減少商品(pin)流通橫(heng)截面；過薄會(hui)在(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂。另外(wai)(wai)內(nei)膠(jiao)(jiao)(jiao)層壁厚(hou)勻稱性(xing)(xing)(xing)也很重要(yao)。假如薄厚(hou)不勻，縮(suo)小(xiao)后(hou)會(hui)導(dao)(dao)致(zhi)一(yi)面裂斷、一(yi)面堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層表層出現的浮銹也是(shi)危害(hai)性(xing)(xing)(xing)能(neng)品(pin)質的關鍵(jian)要(yao)素。
２）高(gao)(gao)壓(ya)(ya)膠(jiao)管關鍵(jian)借助提高(gao)(gao)層(ceng)來承(cheng)受力(li)。手(shou)工(gong)編織(zhi)橡膠(jiao)軟管是(shi)靠膠(jiao)漿與內外(wai)黏膠(jiao)粘(zhan)緊，因(yin)為同一(yi)(yi)手(shou)工(gong)編織(zhi)層(ceng)內不(bu)(bu)(bu)(bu)銹鋼(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)的(de)互(hu)相(xiang)觸碰，在承(cheng)擔(dan)氣(qi)體壓(ya)(ya)力(li)的(de)時(shi)候(hou)會因(yin)分別伸(shen)縮式不(bu)(bu)(bu)(bu)一(yi)(yi)而(er)(er)導致不(bu)(bu)(bu)(bu)銹鋼(gang)(gang)絲(si)彼此之間(jian)(jian)的(de)摩(mo)擦(ca)而(er)(er)危害其(qi)使(shi)用(yong)性(xing)能(neng)(neng)。而(er)(er)螺旋(xuan)波紋管是(shi)由盤繞方位不(bu)(bu)(bu)(bu)一(yi)(yi)樣的(de)雙層(ceng)產生一(yi)(yi)個(ge)工(gong)作中(zhong)(zhong)層(ceng)，在雙層(ceng)中(zhong)(zhong)間(jian)(jian)有(you)正中(zhong)(zhong)間(jian)(jian)膠(jiao)，因(yin)而(er)(er)同一(yi)(yi)工(gong)作中(zhong)(zhong)層(ceng)的(de)雙層(ceng)不(bu)(bu)(bu)(bu)銹鋼(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)沒有(you)交(jiao)(jiao)接點。因(yin)此 不(bu)(bu)(bu)(bu)容易在承(cheng)擔(dan)氣(qi)體壓(ya)(ya)力(li)時(shi)同于(yu)不(bu)(bu)(bu)(bu)銹鋼(gang)(gang)絲(si)間(jian)(jian)的(de)交(jiao)(jiao)叉式彎折(zhe)而(er)(er)產生應力(li)或磨擦(ca)磨壞。故使(shi)用(yong)性(xing)能(neng)(neng)好，能(neng)(neng)承(cheng)擔(dan)髙壓(ya)(ya)。
３）高(gao)(gao)壓膠管的外(wai)膠層粘在提高(gao)(gao)層上起維護功效(xiao)，一般(ban)選用氯丁(ding)膠。應留意(yi)避免(mian) 其脆化(hua)開裂而危害(hai)全部(bu)橡膠軟管的使(shi)用壽命。
