１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)(guan)由內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)(ti)高層(ceng)(ceng)(ceng)和(he)外(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖例(li)），內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立(li)即與液壓(ya)油觸碰(peng)，故規(gui)定(ding)(ding)在(zai)長期性(xing)運行狀態(tai)下(xia)(xia)不(bu)可受液體浸蝕(shi)，能(neng)(neng)補漏。在(zai)提(ti)(ti)高層(ceng)(ceng)(ceng)功(gong)效下(xia)(xia)會承擔一(yi)(yi)定(ding)(ding)工作(zuo)壓(ya)力。因而，宜選用(yong)丁腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)，危(wei)害性(xing)能(neng)(neng)的(de)關(guan)(guan)鍵要素(su)(su)也有內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強度(du)(du)(du)、薄(bo)厚和(he)永(yong)(yong)(yong)久性(xing)形(xing)(xing)變(bian)(bian)量(liang)。強度(du)(du)(du)和(he)永(yong)(yong)(yong)久性(xing)形(xing)(xing)變(bian)(bian)量(liang)對密封(feng)性(xing)性(xing)能(neng)(neng)危(wei)害非常(chang)大。一(yi)(yi)般強度(du)(du)(du)高、縮小(xiao)(xiao)后的(de)永(yong)(yong)(yong)久性(xing)形(xing)(xing)變(bian)(bian)量(liang)小(xiao)(xiao)，密封(feng)性(xing)性(xing)能(neng)(neng)則越(yue)好(hao)。一(yi)(yi)般是(shi)在(zai)７０～８５邵(shao)氏硬度(du)(du)(du)，縮小(xiao)(xiao)永(yong)(yong)(yong)久性(xing)形(xing)(xing)變(bian)(bian)５０％時。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建議是(shi)為(wei)１．５～２．５ｍｍ，太厚會在(zai)壓(ya)扣時提(ti)(ti)升其流(liu)動率，導致不(bu)必要的(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管(guan)(guan)的(de)觸碰(peng)內(nei)孔內(nei)沉積(ji)，減少商(shang)品(pin)(pin)流(liu)通橫截面；過薄(bo)會在(zai)壓(ya)扣時被壓(ya)裂。另(ling)外(wai)內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻(yun)(yun)稱性(xing)也很重要。假如薄(bo)厚不(bu)勻(yun)(yun)，縮小(xiao)(xiao)后會導致一(yi)(yi)面裂斷、一(yi)(yi)面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)浮銹(xiu)也是(shi)危(wei)害性(xing)能(neng)(neng)品(pin)(pin)質的(de)關(guan)(guan)鍵要素(su)(su)。
２）高(gao)壓膠管(guan)關鍵(jian)借助提(ti)高(gao)層(ceng)(ceng)來承(cheng)受(shou)力(li)(li)。手工(gong)(gong)編織橡膠軟(ruan)管(guan)是(shi)靠(kao)膠漿與(yu)內(nei)外(wai)黏膠粘緊，因(yin)為同(tong)一(yi)手工(gong)(gong)編織層(ceng)(ceng)內(nei)不銹鋼(gang)(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)的(de)(de)互相觸碰(peng)，在(zai)承(cheng)擔(dan)氣(qi)體(ti)壓力(li)(li)的(de)(de)時(shi)候會因(yin)分別(bie)伸縮式不一(yi)而(er)(er)導致不銹鋼(gang)(gang)(gang)絲(si)彼此之間(jian)(jian)的(de)(de)摩(mo)擦而(er)(er)危害其使(shi)用(yong)性能(neng)(neng)。而(er)(er)螺(luo)旋波(bo)紋管(guan)是(shi)由盤繞方位不一(yi)樣的(de)(de)雙層(ceng)(ceng)產生(sheng)一(yi)個工(gong)(gong)作中(zhong)(zhong)層(ceng)(ceng)，在(zai)雙層(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)有(you)正中(zhong)(zhong)間(jian)(jian)膠，因(yin)而(er)(er)同(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)層(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)不銹鋼(gang)(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)沒(mei)有(you)交接點。因(yin)此 不容(rong)易在(zai)承(cheng)擔(dan)氣(qi)體(ti)壓力(li)(li)時(shi)同(tong)于不銹鋼(gang)(gang)(gang)絲(si)間(jian)(jian)的(de)(de)交叉式彎(wan)折而(er)(er)產生(sheng)應力(li)(li)或磨擦磨壞。故使(shi)用(yong)性能(neng)(neng)好，能(neng)(neng)承(cheng)擔(dan)髙(gao)壓。
３）高壓(ya)膠(jiao)管的外膠(jiao)層粘在提高層上起維護功效，一般選用氯丁膠(jiao)。應留意避免(mian) 其(qi)脆化開裂而危害(hai)全部橡膠(jiao)軟管的使用壽命(ming)。
