１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)管由內(nei)膠(jiao)層、提(ti)高(gao)(gao)層和外膠(jiao)層構成（如圖例），內(nei)膠(jiao)層立即與液壓(ya)油(you)觸碰(peng)，故(gu)規定在(zai)長(chang)期性(xing)(xing)運行狀態下(xia)不可受液體浸蝕，能(neng)補漏。在(zai)提(ti)高(gao)(gao)層功(gong)效下(xia)會承擔一(yi)定工(gong)作壓(ya)力。因而，宜選用丁腈(jing)橡(xiang)(xiang)膠(jiao)，除塑膠(jiao)粒外，危害性(xing)(xing)能(neng)的(de)(de)(de)關(guan)鍵要(yao)素也(ye)(ye)有內(nei)膠(jiao)層的(de)(de)(de)強(qiang)度(du)、薄厚和永久(jiu)性(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)。強(qiang)度(du)和永久(jiu)性(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)對密封性(xing)(xing)性(xing)(xing)能(neng)危害非(fei)常(chang)大。一(yi)般(ban)(ban)強(qiang)度(du)高(gao)(gao)、縮(suo)小(xiao)后(hou)的(de)(de)(de)永久(jiu)性(xing)(xing)形(xing)變(bian)(bian)量(liang)(liang)小(xiao)，密封性(xing)(xing)性(xing)(xing)能(neng)則越好。一(yi)般(ban)(ban)是(shi)在(zai)７０～８５邵氏硬度(du)，縮(suo)小(xiao)永久(jiu)性(xing)(xing)形(xing)變(bian)(bian)５０％時。內(nei)膠(jiao)層薄厚建議是(shi)為１．５～２．５ｍｍ，太厚會在(zai)壓(ya)扣(kou)時提(ti)升其(qi)流(liu)(liu)動(dong)率，導致不必(bi)要(yao)的(de)(de)(de)膠(jiao)在(zai)接頭芯套(tao)與橡(xiang)(xiang)膠(jiao)軟管的(de)(de)(de)觸碰(peng)內(nei)孔內(nei)沉(chen)積，減少(shao)商品流(liu)(liu)通橫截面；過薄會在(zai)壓(ya)扣(kou)時被壓(ya)裂。另外內(nei)膠(jiao)層壁厚勻稱性(xing)(xing)也(ye)(ye)很重要(yao)。假如薄厚不勻，縮(suo)小(xiao)后(hou)會導致一(yi)面裂斷、一(yi)面堆膠(jiao)。內(nei)膠(jiao)層表層出現(xian)的(de)(de)(de)浮(fu)銹也(ye)(ye)是(shi)危害性(xing)(xing)能(neng)品質的(de)(de)(de)關(guan)鍵要(yao)素。
２）高(gao)壓(ya)膠(jiao)(jiao)(jiao)管(guan)(guan)關鍵借助提高(gao)層(ceng)(ceng)(ceng)來承受力。手工(gong)編織橡膠(jiao)(jiao)(jiao)軟(ruan)管(guan)(guan)是靠膠(jiao)(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)(jiao)粘緊，因(yin)為同一手工(gong)編織層(ceng)(ceng)(ceng)內(nei)不(bu)銹鋼(gang)(gang)絲(si)中(zhong)間(jian)(jian)(jian)(jian)的互相觸碰(peng)，在承擔氣體壓(ya)力的時(shi)候會(hui)因(yin)分別伸縮式不(bu)一而(er)(er)(er)(er)導致不(bu)銹鋼(gang)(gang)絲(si)彼此之間(jian)(jian)(jian)(jian)的摩擦(ca)而(er)(er)(er)(er)危害其(qi)使(shi)用(yong)(yong)性(xing)能(neng)。而(er)(er)(er)(er)螺旋(xuan)波紋管(guan)(guan)是由盤繞方位(wei)不(bu)一樣的雙(shuang)層(ceng)(ceng)(ceng)產生一個工(gong)作中(zhong)層(ceng)(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)(ceng)中(zhong)間(jian)(jian)(jian)(jian)有正中(zhong)間(jian)(jian)(jian)(jian)膠(jiao)(jiao)(jiao)，因(yin)而(er)(er)(er)(er)同一工(gong)作中(zhong)層(ceng)(ceng)(ceng)的雙(shuang)層(ceng)(ceng)(ceng)不(bu)銹鋼(gang)(gang)絲(si)中(zhong)間(jian)(jian)(jian)(jian)沒有交(jiao)(jiao)接(jie)點(dian)。因(yin)此 不(bu)容易在承擔氣體壓(ya)力時(shi)同于不(bu)銹鋼(gang)(gang)絲(si)間(jian)(jian)(jian)(jian)的交(jiao)(jiao)叉式彎折而(er)(er)(er)(er)產生應(ying)力或磨擦(ca)磨壞。故使(shi)用(yong)(yong)性(xing)能(neng)好，能(neng)承擔髙壓(ya)。
３）高壓膠(jiao)管的外膠(jiao)層(ceng)粘在提高層(ceng)上起維(wei)護(hu)功效(xiao)，一(yi)般選用氯丁膠(jiao)。應留意避(bi)免(mian) 其脆化開(kai)裂而危害(hai)全部橡膠(jiao)軟管的使用壽(shou)命。
