１、橡膠軟管總成
1）高(gao)(gao)(gao)壓(ya)膠(jiao)(jiao)管(guan)(guan)由內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)、提(ti)高(gao)(gao)(gao)層(ceng)和(he)外膠(jiao)(jiao)層(ceng)構成（如(ru)圖例），內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)立即與液壓(ya)油觸碰，故(gu)規定(ding)在(zai)(zai)長期(qi)性(xing)(xing)(xing)運行狀態下(xia)不(bu)可受液體(ti)浸蝕，能(neng)(neng)補漏。在(zai)(zai)提(ti)高(gao)(gao)(gao)層(ceng)功效(xiao)下(xia)會承擔一(yi)(yi)定(ding)工作壓(ya)力(li)。因而，宜選用(yong)丁腈(jing)橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒外，危(wei)害(hai)性(xing)(xing)(xing)能(neng)(neng)的(de)關鍵(jian)要(yao)(yao)素(su)(su)也有內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)的(de)強(qiang)度(du)(du)、薄厚(hou)和(he)永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形變(bian)(bian)(bian)量(liang)。強(qiang)度(du)(du)和(he)永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形變(bian)(bian)(bian)量(liang)對密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)危(wei)害(hai)非常大。一(yi)(yi)般(ban)(ban)強(qiang)度(du)(du)高(gao)(gao)(gao)、縮(suo)小(xiao)后(hou)的(de)永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形變(bian)(bian)(bian)量(liang)小(xiao)，密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)則越好。一(yi)(yi)般(ban)(ban)是在(zai)(zai)７０～８５邵氏硬度(du)(du)，縮(suo)小(xiao)永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形變(bian)(bian)(bian)５０％時(shi)。內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)薄厚(hou)建議是為１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)(zai)壓(ya)扣時(shi)提(ti)升其流動率(lv)，導致(zhi)不(bu)必(bi)要(yao)(yao)的(de)膠(jiao)(jiao)在(zai)(zai)接頭芯(xin)套與橡膠(jiao)(jiao)軟(ruan)管(guan)(guan)的(de)觸碰內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商品(pin)流通橫截面(mian)；過薄會在(zai)(zai)壓(ya)扣時(shi)被壓(ya)裂(lie)。另外內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)也很重要(yao)(yao)。假(jia)如(ru)薄厚(hou)不(bu)勻，縮(suo)小(xiao)后(hou)會導致(zhi)一(yi)(yi)面(mian)裂(lie)斷、一(yi)(yi)面(mian)堆膠(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)層(ceng)表層(ceng)出現的(de)浮(fu)銹也是危(wei)害(hai)性(xing)(xing)(xing)能(neng)(neng)品(pin)質的(de)關鍵(jian)要(yao)(yao)素(su)(su)。
２）高壓(ya)膠(jiao)管(guan)關鍵借助提高層(ceng)來承受力。手工(gong)編(bian)(bian)織橡膠(jiao)軟管(guan)是靠(kao)膠(jiao)漿(jiang)與內(nei)外(wai)黏膠(jiao)粘緊，因(yin)為同(tong)一手工(gong)編(bian)(bian)織層(ceng)內(nei)不(bu)(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)(zhong)間(jian)(jian)的(de)互相(xiang)觸碰(peng)，在(zai)承擔(dan)氣(qi)體壓(ya)力的(de)時(shi)候會因(yin)分別伸縮式不(bu)(bu)(bu)一而導致不(bu)(bu)(bu)銹(xiu)鋼(gang)絲彼此之間(jian)(jian)的(de)摩擦(ca)而危害(hai)其使(shi)用(yong)性(xing)能。而螺旋波(bo)紋管(guan)是由盤繞方位不(bu)(bu)(bu)一樣的(de)雙層(ceng)產(chan)生一個工(gong)作(zuo)中(zhong)(zhong)(zhong)層(ceng)，在(zai)雙層(ceng)中(zhong)(zhong)(zhong)間(jian)(jian)有(you)(you)正(zheng)中(zhong)(zhong)(zhong)間(jian)(jian)膠(jiao)，因(yin)而同(tong)一工(gong)作(zuo)中(zhong)(zhong)(zhong)層(ceng)的(de)雙層(ceng)不(bu)(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)(zhong)間(jian)(jian)沒有(you)(you)交接點。因(yin)此 不(bu)(bu)(bu)容易在(zai)承擔(dan)氣(qi)體壓(ya)力時(shi)同(tong)于不(bu)(bu)(bu)銹(xiu)鋼(gang)絲間(jian)(jian)的(de)交叉式彎(wan)折而產(chan)生應(ying)力或磨擦(ca)磨壞。故使(shi)用(yong)性(xing)能好，能承擔(dan)髙壓(ya)。
３）高(gao)壓膠(jiao)管的外膠(jiao)層(ceng)(ceng)粘在提高(gao)層(ceng)(ceng)上起維護功效，一般選用氯丁膠(jiao)。應留意(yi)避免(mian) 其(qi)脆化開裂而危害全部(bu)橡膠(jiao)軟管的使用壽命。
