１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)管由內膠(jiao)(jiao)層(ceng)(ceng)、提(ti)高(gao)層(ceng)(ceng)和(he)外膠(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如圖(tu)例），內膠(jiao)(jiao)層(ceng)(ceng)立即與(yu)液(ye)壓(ya)油觸碰，故規(gui)定(ding)在(zai)(zai)長(chang)期性(xing)(xing)(xing)(xing)(xing)(xing)運(yun)行狀態下(xia)不可受(shou)液(ye)體浸蝕，能補漏。在(zai)(zai)提(ti)高(gao)層(ceng)(ceng)功效(xiao)下(xia)會承擔一(yi)(yi)定(ding)工作(zuo)壓(ya)力。因而，宜(yi)選(xuan)用丁腈橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外，危害(hai)性(xing)(xing)(xing)(xing)(xing)(xing)能的關(guan)鍵要(yao)素也(ye)有內膠(jiao)(jiao)層(ceng)(ceng)的強(qiang)度、薄(bo)(bo)厚和(he)永久性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)量。強(qiang)度和(he)永久性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)量對密(mi)封性(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)能危害(hai)非常大。一(yi)(yi)般強(qiang)度高(gao)、縮(suo)小(xiao)后的永久性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)量小(xiao)，密(mi)封性(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)能則越好。一(yi)(yi)般是(shi)在(zai)(zai)７０～８５邵(shao)氏硬度，縮(suo)小(xiao)永久性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)５０％時(shi)。內膠(jiao)(jiao)層(ceng)(ceng)薄(bo)(bo)厚建(jian)議是(shi)為(wei)１．５～２．５ｍｍ，太厚會在(zai)(zai)壓(ya)扣時(shi)提(ti)升其流動率，導(dao)致(zhi)不必要(yao)的膠(jiao)(jiao)在(zai)(zai)接頭芯套(tao)與(yu)橡膠(jiao)(jiao)軟管的觸碰內孔內沉積，減少商品流通橫截面；過薄(bo)(bo)會在(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂。另外內膠(jiao)(jiao)層(ceng)(ceng)壁(bi)厚勻稱(cheng)性(xing)(xing)(xing)(xing)(xing)(xing)也(ye)很重要(yao)。假如薄(bo)(bo)厚不勻，縮(suo)小(xiao)后會導(dao)致(zhi)一(yi)(yi)面裂斷、一(yi)(yi)面堆膠(jiao)(jiao)。內膠(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的浮(fu)銹也(ye)是(shi)危害(hai)性(xing)(xing)(xing)(xing)(xing)(xing)能品質(zhi)的關(guan)鍵要(yao)素。
２）高(gao)壓膠(jiao)(jiao)管關鍵借助提高(gao)層來(lai)承(cheng)受力。手工(gong)(gong)編(bian)織(zhi)橡(xiang)膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊，因(yin)為(wei)同一(yi)(yi)(yi)手工(gong)(gong)編(bian)織(zhi)層內不(bu)銹鋼(gang)絲中間(jian)的(de)(de)(de)互相觸碰，在(zai)承(cheng)擔氣體壓力的(de)(de)(de)時(shi)候會因(yin)分別伸縮式(shi)不(bu)一(yi)(yi)(yi)而(er)導致不(bu)銹鋼(gang)絲彼此之(zhi)間(jian)的(de)(de)(de)摩擦而(er)危害其使用(yong)性(xing)能。而(er)螺(luo)旋波紋管是由盤繞(rao)方位不(bu)一(yi)(yi)(yi)樣的(de)(de)(de)雙層產生一(yi)(yi)(yi)個(ge)工(gong)(gong)作中層，在(zai)雙層中間(jian)有(you)正(zheng)中間(jian)膠(jiao)(jiao)，因(yin)而(er)同一(yi)(yi)(yi)工(gong)(gong)作中層的(de)(de)(de)雙層不(bu)銹鋼(gang)絲中間(jian)沒有(you)交(jiao)接點(dian)。因(yin)此 不(bu)容易(yi)在(zai)承(cheng)擔氣體壓力時(shi)同于不(bu)銹鋼(gang)絲間(jian)的(de)(de)(de)交(jiao)叉(cha)式(shi)彎折(zhe)而(er)產生應(ying)力或磨擦磨壞。故(gu)使用(yong)性(xing)能好，能承(cheng)擔髙壓。
３）高壓膠(jiao)管(guan)的外膠(jiao)層粘在提高層上(shang)起(qi)維護功效，一般(ban)選用(yong)氯丁膠(jiao)。應(ying)留意避免 其脆化開裂而危(wei)害(hai)全部(bu)橡膠(jiao)軟管(guan)的使用(yong)壽命。
