１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)管由(you)內(nei)膠(jiao)(jiao)(jiao)層、提高(gao)(gao)層和(he)外膠(jiao)(jiao)(jiao)層構成（如圖例），內(nei)膠(jiao)(jiao)(jiao)層立(li)即與液(ye)壓(ya)油觸碰，故規定在(zai)(zai)長(chang)期性(xing)(xing)(xing)運行狀態(tai)下不(bu)可受液(ye)體浸(jin)蝕，能(neng)補漏。在(zai)(zai)提高(gao)(gao)層功效下會承擔(dan)一定工作壓(ya)力(li)。因(yin)而，宜選用丁腈橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外，危害性(xing)(xing)(xing)能(neng)的(de)(de)(de)關鍵(jian)要(yao)素也(ye)有內(nei)膠(jiao)(jiao)(jiao)層的(de)(de)(de)強度(du)、薄(bo)厚和(he)永久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量(liang)。強度(du)和(he)永久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量(liang)對密封(feng)(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害非常大。一般(ban)強度(du)高(gao)(gao)、縮小后(hou)的(de)(de)(de)永久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量(liang)小，密封(feng)(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則(ze)越好。一般(ban)是(shi)在(zai)(zai)７０～８５邵(shao)氏硬度(du)，縮小永久(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)５０％時(shi)(shi)。內(nei)膠(jiao)(jiao)(jiao)層薄(bo)厚建議是(shi)為１．５～２．５ｍｍ，太厚會在(zai)(zai)壓(ya)扣時(shi)(shi)提升(sheng)其流動率，導致(zhi)不(bu)必(bi)要(yao)的(de)(de)(de)膠(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)軟管的(de)(de)(de)觸碰內(nei)孔內(nei)沉積，減(jian)少商品流通橫截面；過薄(bo)會在(zai)(zai)壓(ya)扣時(shi)(shi)被壓(ya)裂(lie)。另(ling)外內(nei)膠(jiao)(jiao)(jiao)層壁厚勻稱性(xing)(xing)(xing)也(ye)很(hen)重(zhong)要(yao)。假如薄(bo)厚不(bu)勻，縮小后(hou)會導致(zhi)一面裂(lie)斷、一面堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層表層出現的(de)(de)(de)浮(fu)銹也(ye)是(shi)危害性(xing)(xing)(xing)能(neng)品質的(de)(de)(de)關鍵(jian)要(yao)素。
２）高壓(ya)(ya)膠(jiao)(jiao)管(guan)關鍵借助提(ti)高層(ceng)來承受(shou)力(li)。手工(gong)(gong)編織橡膠(jiao)(jiao)軟管(guan)是靠膠(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)粘緊(jin)，因(yin)(yin)為(wei)同(tong)(tong)(tong)一(yi)手工(gong)(gong)編織層(ceng)內(nei)不(bu)銹(xiu)(xiu)鋼(gang)絲中(zhong)間(jian)(jian)的(de)互(hu)相觸(chu)碰，在承擔氣體壓(ya)(ya)力(li)的(de)時(shi)候會因(yin)(yin)分別伸縮式不(bu)一(yi)而導(dao)致不(bu)銹(xiu)(xiu)鋼(gang)絲彼(bi)此(ci)之(zhi)間(jian)(jian)的(de)摩擦(ca)而危(wei)害(hai)其(qi)使(shi)用性能。而螺旋波紋管(guan)是由(you)盤繞方位不(bu)一(yi)樣的(de)雙層(ceng)產(chan)生(sheng)一(yi)個工(gong)(gong)作(zuo)(zuo)中(zhong)層(ceng)，在雙層(ceng)中(zhong)間(jian)(jian)有正中(zhong)間(jian)(jian)膠(jiao)(jiao)，因(yin)(yin)而同(tong)(tong)(tong)一(yi)工(gong)(gong)作(zuo)(zuo)中(zhong)層(ceng)的(de)雙層(ceng)不(bu)銹(xiu)(xiu)鋼(gang)絲中(zhong)間(jian)(jian)沒有交(jiao)接點。因(yin)(yin)此(ci) 不(bu)容易在承擔氣體壓(ya)(ya)力(li)時(shi)同(tong)(tong)(tong)于不(bu)銹(xiu)(xiu)鋼(gang)絲間(jian)(jian)的(de)交(jiao)叉式彎折(zhe)而產(chan)生(sheng)應(ying)力(li)或(huo)磨(mo)擦(ca)磨(mo)壞。故使(shi)用性能好，能承擔髙壓(ya)(ya)。
３）高壓(ya)膠(jiao)管的(de)外膠(jiao)層粘在提高層上(shang)起維(wei)護功效，一(yi)般選用氯丁(ding)膠(jiao)。應留(liu)意避免 其脆(cui)化開裂而危害全部橡(xiang)膠(jiao)軟管的(de)使(shi)用壽命。
