１、橡膠軟管總成
1）高(gao)(gao)壓(ya)(ya)(ya)膠(jiao)(jiao)管(guan)由內膠(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)(gao)層(ceng)(ceng)和(he)外膠(jiao)(jiao)層(ceng)(ceng)構成（如(ru)圖例），內膠(jiao)(jiao)層(ceng)(ceng)立即與液(ye)壓(ya)(ya)(ya)油觸碰，故規(gui)定在(zai)長期性(xing)(xing)(xing)運行(xing)狀態下不可(ke)受液(ye)體(ti)浸蝕，能(neng)補漏。在(zai)提(ti)高(gao)(gao)層(ceng)(ceng)功效下會(hui)承擔一定工作壓(ya)(ya)(ya)力。因而(er)，宜選用丁腈(jing)橡(xiang)(xiang)膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外，危害性(xing)(xing)(xing)能(neng)的(de)關鍵要素也有內膠(jiao)(jiao)層(ceng)(ceng)的(de)強度(du)、薄(bo)厚(hou)(hou)(hou)和(he)永(yong)久性(xing)(xing)(xing)形(xing)變(bian)量。強度(du)和(he)永(yong)久性(xing)(xing)(xing)形(xing)變(bian)量對密(mi)封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害非常大。一般強度(du)高(gao)(gao)、縮(suo)小后的(de)永(yong)久性(xing)(xing)(xing)形(xing)變(bian)量小，密(mi)封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越(yue)好。一般是(shi)在(zai)７０～８５邵氏硬度(du)，縮(suo)小永(yong)久性(xing)(xing)(xing)形(xing)變(bian)５０％時。內膠(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)(hou)(hou)建議(yi)是(shi)為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會(hui)在(zai)壓(ya)(ya)(ya)扣(kou)時提(ti)升其流(liu)動率(lv)，導(dao)(dao)致(zhi)(zhi)不必要的(de)膠(jiao)(jiao)在(zai)接頭芯套與橡(xiang)(xiang)膠(jiao)(jiao)軟管(guan)的(de)觸碰內孔內沉積，減少商(shang)品流(liu)通橫截(jie)面；過薄(bo)會(hui)在(zai)壓(ya)(ya)(ya)扣(kou)時被壓(ya)(ya)(ya)裂。另(ling)外內膠(jiao)(jiao)層(ceng)(ceng)壁厚(hou)(hou)(hou)勻(yun)稱性(xing)(xing)(xing)也很(hen)重要。假如(ru)薄(bo)厚(hou)(hou)(hou)不勻(yun)，縮(suo)小后會(hui)導(dao)(dao)致(zhi)(zhi)一面裂斷、一面堆膠(jiao)(jiao)。內膠(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現(xian)的(de)浮銹也是(shi)危害性(xing)(xing)(xing)能(neng)品質的(de)關鍵要素。
２）高(gao)壓(ya)膠(jiao)(jiao)管(guan)(guan)關(guan)鍵借助提(ti)高(gao)層(ceng)(ceng)來(lai)承(cheng)(cheng)受力。手(shou)工編(bian)織橡(xiang)膠(jiao)(jiao)軟管(guan)(guan)是(shi)靠膠(jiao)(jiao)漿(jiang)與內外黏膠(jiao)(jiao)粘緊，因(yin)(yin)為同(tong)一(yi)手(shou)工編(bian)織層(ceng)(ceng)內不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)(jian)的互相觸碰，在承(cheng)(cheng)擔(dan)(dan)氣體壓(ya)力的時候會因(yin)(yin)分別伸縮式不(bu)(bu)一(yi)而導致不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)絲(si)彼此(ci)之(zhi)間(jian)(jian)(jian)的摩擦而危(wei)害(hai)其(qi)使(shi)用(yong)性能(neng)。而螺旋(xuan)波紋管(guan)(guan)是(shi)由盤繞方位(wei)不(bu)(bu)一(yi)樣(yang)的雙層(ceng)(ceng)產(chan)生一(yi)個工作中(zhong)(zhong)層(ceng)(ceng)，在雙層(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)(jian)有(you)(you)正中(zhong)(zhong)間(jian)(jian)(jian)膠(jiao)(jiao)，因(yin)(yin)而同(tong)一(yi)工作中(zhong)(zhong)層(ceng)(ceng)的雙層(ceng)(ceng)不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)絲(si)中(zhong)(zhong)間(jian)(jian)(jian)沒有(you)(you)交接點。因(yin)(yin)此(ci) 不(bu)(bu)容易在承(cheng)(cheng)擔(dan)(dan)氣體壓(ya)力時同(tong)于(yu)不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)絲(si)間(jian)(jian)(jian)的交叉式彎折而產(chan)生應力或(huo)磨(mo)擦磨(mo)壞。故(gu)使(shi)用(yong)性能(neng)好，能(neng)承(cheng)(cheng)擔(dan)(dan)髙壓(ya)。
３）高壓膠管的外膠層粘在(zai)提高層上起維護功(gong)效，一(yi)般選用(yong)氯丁膠。應(ying)留意避免 其脆化開裂而(er)危害(hai)全部橡膠軟管的使(shi)用(yong)壽(shou)命。
