１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)由內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)(ceng)和外(wai)(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如(ru)圖(tu)例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即與液壓(ya)油觸碰，故規(gui)定在長(chang)期性(xing)(xing)運行狀態下(xia)不(bu)可受液體浸蝕，能(neng)補漏。在提(ti)高層(ceng)(ceng)(ceng)(ceng)功效下(xia)會(hui)承(cheng)擔一(yi)定工作壓(ya)力(li)。因而，宜(yi)選用丁腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)(wai)(wai)，危害(hai)性(xing)(xing)能(neng)的(de)(de)關鍵要(yao)素也(ye)有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)(de)強度、薄厚和永久(jiu)性(xing)(xing)形變(bian)量。強度和永久(jiu)性(xing)(xing)形變(bian)量對密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)危害(hai)非常(chang)大(da)。一(yi)般(ban)強度高、縮(suo)小(xiao)后的(de)(de)永久(jiu)性(xing)(xing)形變(bian)量小(xiao)，密(mi)封(feng)性(xing)(xing)性(xing)(xing)能(neng)則越好。一(yi)般(ban)是(shi)在７０～８５邵氏(shi)硬度，縮(suo)小(xiao)永久(jiu)性(xing)(xing)形變(bian)５０％時。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄厚建議是(shi)為１．５～２．５ｍｍ，太厚會(hui)在壓(ya)扣時提(ti)升其(qi)流動率，導(dao)致不(bu)必要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在接頭芯套與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積，減少商品流通(tong)橫截面；過薄會(hui)在壓(ya)扣時被壓(ya)裂。另外(wai)(wai)(wai)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚勻稱性(xing)(xing)也(ye)很重要(yao)。假如(ru)薄厚不(bu)勻，縮(suo)小(xiao)后會(hui)導(dao)致一(yi)面裂斷、一(yi)面堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表(biao)層(ceng)(ceng)(ceng)(ceng)出現(xian)的(de)(de)浮銹也(ye)是(shi)危害(hai)性(xing)(xing)能(neng)品質的(de)(de)關鍵要(yao)素。
２）高壓(ya)(ya)(ya)膠管關鍵借助提高層(ceng)(ceng)(ceng)(ceng)(ceng)來(lai)承受力(li)。手工(gong)編織橡膠軟管是靠膠漿與(yu)內外黏膠粘緊，因(yin)為(wei)同一(yi)(yi)手工(gong)編織層(ceng)(ceng)(ceng)(ceng)(ceng)內不(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)間的(de)(de)互相觸碰，在承擔氣體壓(ya)(ya)(ya)力(li)的(de)(de)時(shi)候會因(yin)分別伸縮(suo)式不(bu)(bu)一(yi)(yi)而(er)導(dao)致不(bu)(bu)銹(xiu)鋼(gang)絲彼此(ci)之(zhi)間的(de)(de)摩擦而(er)危害(hai)其使用性能。而(er)螺旋波紋管是由盤繞方位不(bu)(bu)一(yi)(yi)樣的(de)(de)雙層(ceng)(ceng)(ceng)(ceng)(ceng)產生(sheng)一(yi)(yi)個(ge)工(gong)作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)，在雙層(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)(zhong)間有正中(zhong)(zhong)間膠，因(yin)而(er)同一(yi)(yi)工(gong)作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)(ceng)(ceng)(ceng)不(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)間沒有交接點。因(yin)此(ci) 不(bu)(bu)容易在承擔氣體壓(ya)(ya)(ya)力(li)時(shi)同于不(bu)(bu)銹(xiu)鋼(gang)絲間的(de)(de)交叉式彎(wan)折而(er)產生(sheng)應力(li)或磨擦磨壞。故(gu)使用性能好，能承擔髙壓(ya)(ya)(ya)。
３）高(gao)壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層(ceng)粘在提高(gao)層(ceng)上起維(wei)護(hu)功效，一般(ban)選用氯丁膠(jiao)(jiao)。應留意(yi)避免 其脆化開裂而危(wei)害全(quan)部橡膠(jiao)(jiao)軟(ruan)管的使用壽(shou)命。
