１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高(gao)(gao)層(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構(gou)成（如圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與液壓(ya)油觸碰(peng)，故規定在(zai)(zai)長期(qi)性(xing)(xing)(xing)(xing)(xing)運行狀(zhuang)態下不可受液體浸蝕，能(neng)補漏。在(zai)(zai)提高(gao)(gao)層(ceng)(ceng)(ceng)功效下會(hui)承擔一(yi)定工作壓(ya)力。因而(er)，宜(yi)選(xuan)用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)的(de)關鍵要(yao)(yao)素也(ye)有內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強(qiang)(qiang)度、薄厚和(he)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)。強(qiang)(qiang)度和(he)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)對密(mi)封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)危害(hai)非常大。一(yi)般(ban)強(qiang)(qiang)度高(gao)(gao)、縮小后(hou)的(de)永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)量(liang)小，密(mi)封性(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)能(neng)則越(yue)好。一(yi)般(ban)是(shi)在(zai)(zai)７０～８５邵氏硬度，縮小永(yong)久(jiu)(jiu)性(xing)(xing)(xing)(xing)(xing)形變(bian)(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄厚建(jian)議(yi)是(shi)為１．５～２．５ｍｍ，太厚會(hui)在(zai)(zai)壓(ya)扣時(shi)提升其流動率，導致(zhi)不必要(yao)(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯(xin)套(tao)與橡膠(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰(peng)內(nei)孔(kong)內(nei)沉積，減(jian)少(shao)商(shang)品流通橫截面(mian)；過薄會(hui)在(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂(lie)。另外內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁(bi)厚勻(yun)稱性(xing)(xing)(xing)(xing)(xing)也(ye)很重要(yao)(yao)。假如薄厚不勻(yun)，縮小后(hou)會(hui)導致(zhi)一(yi)面(mian)裂(lie)斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)浮(fu)銹也(ye)是(shi)危害(hai)性(xing)(xing)(xing)(xing)(xing)能(neng)品質的(de)關鍵要(yao)(yao)素。
２）高壓(ya)膠(jiao)管關鍵借助提高層(ceng)(ceng)來承受(shou)力。手工編(bian)(bian)織橡膠(jiao)軟管是靠膠(jiao)漿與內(nei)外黏膠(jiao)粘緊，因為(wei)同(tong)一(yi)手工編(bian)(bian)織層(ceng)(ceng)內(nei)不(bu)(bu)(bu)(bu)銹(xiu)鋼絲(si)中(zhong)(zhong)(zhong)間(jian)(jian)(jian)(jian)的(de)(de)互(hu)相觸碰，在承擔氣(qi)體(ti)壓(ya)力的(de)(de)時候會因分別伸縮式(shi)不(bu)(bu)(bu)(bu)一(yi)而(er)導致不(bu)(bu)(bu)(bu)銹(xiu)鋼絲(si)彼此(ci)之間(jian)(jian)(jian)(jian)的(de)(de)摩擦而(er)危(wei)害其(qi)使(shi)用(yong)性(xing)能。而(er)螺旋波紋管是由盤(pan)繞方位不(bu)(bu)(bu)(bu)一(yi)樣的(de)(de)雙(shuang)層(ceng)(ceng)產(chan)生一(yi)個(ge)工作(zuo)中(zhong)(zhong)(zhong)層(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)中(zhong)(zhong)(zhong)間(jian)(jian)(jian)(jian)有正(zheng)中(zhong)(zhong)(zhong)間(jian)(jian)(jian)(jian)膠(jiao)，因而(er)同(tong)一(yi)工作(zuo)中(zhong)(zhong)(zhong)層(ceng)(ceng)的(de)(de)雙(shuang)層(ceng)(ceng)不(bu)(bu)(bu)(bu)銹(xiu)鋼絲(si)中(zhong)(zhong)(zhong)間(jian)(jian)(jian)(jian)沒(mei)有交接點。因此(ci) 不(bu)(bu)(bu)(bu)容易在承擔氣(qi)體(ti)壓(ya)力時同(tong)于不(bu)(bu)(bu)(bu)銹(xiu)鋼絲(si)間(jian)(jian)(jian)(jian)的(de)(de)交叉(cha)式(shi)彎折而(er)產(chan)生應(ying)力或磨(mo)(mo)擦磨(mo)(mo)壞。故使(shi)用(yong)性(xing)能好，能承擔髙壓(ya)。
３）高壓膠(jiao)(jiao)管(guan)的外膠(jiao)(jiao)層粘在提高層上(shang)起(qi)維護功效，一般選用(yong)氯(lv)丁膠(jiao)(jiao)。應留(liu)意避免 其脆(cui)化開裂而危害全部橡膠(jiao)(jiao)軟管(guan)的使(shi)用(yong)壽命。
