１、橡膠軟管總成
1）高壓膠(jiao)(jiao)(jiao)(jiao)管(guan)由內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提(ti)高層(ceng)(ceng)和外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如圖例），內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液壓油觸碰(peng)，故規定(ding)在(zai)長期性(xing)(xing)運行狀態下不可受液體浸蝕，能(neng)(neng)(neng)補漏(lou)。在(zai)提(ti)高層(ceng)(ceng)功效下會(hui)承擔一定(ding)工作壓力。因而，宜選(xuan)用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒(li)外，危害性(xing)(xing)能(neng)(neng)(neng)的(de)(de)(de)關(guan)鍵(jian)要(yao)素也(ye)有內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)(de)強度、薄厚和永(yong)久(jiu)性(xing)(xing)形(xing)變量。強度和永(yong)久(jiu)性(xing)(xing)形(xing)變量對(dui)密封(feng)性(xing)(xing)性(xing)(xing)能(neng)(neng)(neng)危害非常(chang)大。一般強度高、縮小(xiao)(xiao)后的(de)(de)(de)永(yong)久(jiu)性(xing)(xing)形(xing)變量小(xiao)(xiao)，密封(feng)性(xing)(xing)性(xing)(xing)能(neng)(neng)(neng)則越好(hao)。一般是(shi)(shi)在(zai)７０～８５邵氏(shi)硬度，縮小(xiao)(xiao)永(yong)久(jiu)性(xing)(xing)形(xing)變５０％時。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄厚建議是(shi)(shi)為１．５～２．５ｍｍ，太(tai)厚會(hui)在(zai)壓扣時提(ti)升其流動率，導致不必要(yao)的(de)(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)(de)觸碰(peng)內孔內沉積，減少商品(pin)流通橫截面；過薄會(hui)在(zai)壓扣時被(bei)壓裂。另外內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚勻稱性(xing)(xing)也(ye)很重(zhong)要(yao)。假如薄厚不勻，縮小(xiao)(xiao)后會(hui)導致一面裂斷、一面堆膠(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)(de)浮銹也(ye)是(shi)(shi)危害性(xing)(xing)能(neng)(neng)(neng)品(pin)質的(de)(de)(de)關(guan)鍵(jian)要(yao)素。
２）高壓(ya)膠(jiao)(jiao)(jiao)管(guan)關(guan)鍵借助(zhu)提高層(ceng)(ceng)(ceng)(ceng)來承受力(li)(li)。手(shou)工編織橡膠(jiao)(jiao)(jiao)軟管(guan)是(shi)靠膠(jiao)(jiao)(jiao)漿與內外黏膠(jiao)(jiao)(jiao)粘緊(jin)，因(yin)為同一(yi)(yi)手(shou)工編織層(ceng)(ceng)(ceng)(ceng)內不(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)(si)中(zhong)(zhong)間(jian)(jian)的(de)互(hu)相觸碰，在承擔氣(qi)體壓(ya)力(li)(li)的(de)時候會因(yin)分別伸縮式不(bu)(bu)(bu)一(yi)(yi)而(er)導(dao)致不(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)(si)彼此之間(jian)(jian)的(de)摩擦而(er)危(wei)害其使(shi)用性能(neng)。而(er)螺旋波紋管(guan)是(shi)由盤(pan)繞方位不(bu)(bu)(bu)一(yi)(yi)樣(yang)的(de)雙層(ceng)(ceng)(ceng)(ceng)產生一(yi)(yi)個工作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)有(you)正中(zhong)(zhong)間(jian)(jian)膠(jiao)(jiao)(jiao)，因(yin)而(er)同一(yi)(yi)工作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)的(de)雙層(ceng)(ceng)(ceng)(ceng)不(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)(si)中(zhong)(zhong)間(jian)(jian)沒有(you)交接點。因(yin)此 不(bu)(bu)(bu)容易在承擔氣(qi)體壓(ya)力(li)(li)時同于(yu)不(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)(si)間(jian)(jian)的(de)交叉式彎折而(er)產生應力(li)(li)或磨擦磨壞。故(gu)使(shi)用性能(neng)好，能(neng)承擔髙壓(ya)。
３）高壓膠(jiao)管(guan)(guan)的外膠(jiao)層粘(zhan)在提高層上起(qi)維(wei)護功效，一般(ban)選用氯丁(ding)膠(jiao)。應留意避免 其(qi)脆化(hua)開裂而危害全部橡膠(jiao)軟管(guan)(guan)的使用壽命。
