１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)管由(you)內(nei)(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)、提高(gao)層(ceng)(ceng)和(he)外(wai)膠(jiao)(jiao)層(ceng)(ceng)構成（如圖例(li)），內(nei)(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)立即與液(ye)壓(ya)油觸碰，故規(gui)定在(zai)(zai)長期性(xing)(xing)(xing)(xing)運行(xing)狀(zhuang)態下不可受液(ye)體浸蝕，能(neng)(neng)補漏。在(zai)(zai)提高(gao)層(ceng)(ceng)功(gong)效下會(hui)承(cheng)擔(dan)一(yi)定工作(zuo)壓(ya)力。因而，宜選用丁(ding)腈橡膠(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)粒(li)外(wai)，危害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)的(de)(de)關(guan)鍵要(yao)素也有內(nei)(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)的(de)(de)強度(du)、薄厚(hou)(hou)(hou)和(he)永(yong)(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量。強度(du)和(he)永(yong)(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量對密(mi)(mi)封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)危害(hai)非(fei)常大(da)。一(yi)般強度(du)高(gao)、縮小后(hou)的(de)(de)永(yong)(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)量小，密(mi)(mi)封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)則越好(hao)。一(yi)般是在(zai)(zai)７０～８５邵氏(shi)硬度(du)，縮小永(yong)(yong)久性(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時(shi)(shi)。內(nei)(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)薄厚(hou)(hou)(hou)建議是為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會(hui)在(zai)(zai)壓(ya)扣時(shi)(shi)提升其流動率(lv)，導致(zhi)不必(bi)要(yao)的(de)(de)膠(jiao)(jiao)在(zai)(zai)接頭(tou)芯(xin)套與橡膠(jiao)(jiao)軟管的(de)(de)觸碰內(nei)(nei)(nei)(nei)孔內(nei)(nei)(nei)(nei)沉積，減少(shao)商品(pin)流通橫截(jie)面；過薄會(hui)在(zai)(zai)壓(ya)扣時(shi)(shi)被壓(ya)裂(lie)。另外(wai)內(nei)(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)壁厚(hou)(hou)(hou)勻稱性(xing)(xing)(xing)(xing)也很重要(yao)。假如薄厚(hou)(hou)(hou)不勻，縮小后(hou)會(hui)導致(zhi)一(yi)面裂(lie)斷、一(yi)面堆膠(jiao)(jiao)。內(nei)(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)浮銹也是危害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)品(pin)質的(de)(de)關(guan)鍵要(yao)素。
２）高壓(ya)膠(jiao)(jiao)管關(guan)鍵借助提高層(ceng)(ceng)(ceng)來承(cheng)受力(li)。手工編織橡膠(jiao)(jiao)軟管是靠(kao)膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊，因為同(tong)一手工編織層(ceng)(ceng)(ceng)內不(bu)(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間(jian)(jian)的(de)(de)互相觸碰，在承(cheng)擔(dan)(dan)氣體壓(ya)力(li)的(de)(de)時候(hou)會因分別伸縮式(shi)不(bu)(bu)一而導(dao)致(zhi)不(bu)(bu)銹鋼(gang)絲(si)彼此(ci)之間(jian)(jian)的(de)(de)摩(mo)擦而危害其使用性(xing)能(neng)(neng)(neng)。而螺(luo)旋波紋管是由(you)盤(pan)繞方位不(bu)(bu)一樣的(de)(de)雙層(ceng)(ceng)(ceng)產生一個工作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)有正中(zhong)(zhong)間(jian)(jian)膠(jiao)(jiao)，因而同(tong)一工作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)(ceng)不(bu)(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間(jian)(jian)沒有交接點。因此(ci) 不(bu)(bu)容易(yi)在承(cheng)擔(dan)(dan)氣體壓(ya)力(li)時同(tong)于不(bu)(bu)銹鋼(gang)絲(si)間(jian)(jian)的(de)(de)交叉式(shi)彎折而產生應力(li)或磨擦磨壞(huai)。故(gu)使用性(xing)能(neng)(neng)(neng)好，能(neng)(neng)(neng)承(cheng)擔(dan)(dan)髙壓(ya)。
３）高壓膠(jiao)管的外膠(jiao)層(ceng)粘(zhan)在提高層(ceng)上起(qi)維護功效，一(yi)般(ban)選(xuan)用氯丁膠(jiao)。應(ying)留(liu)意避免 其(qi)脆化開裂而危害全部橡(xiang)膠(jiao)軟管的使用壽命。
