１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由(you)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)(ceng)和(he)(he)外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即(ji)與液壓(ya)(ya)油觸碰(peng)，故規定(ding)在(zai)(zai)長期性(xing)(xing)(xing)運行(xing)狀態下不(bu)(bu)(bu)可受液體浸蝕，能(neng)補(bu)漏。在(zai)(zai)提高(gao)層(ceng)(ceng)(ceng)(ceng)功效下會承擔一(yi)定(ding)工作壓(ya)(ya)力。因(yin)而，宜選(xuan)用丁(ding)腈(jing)橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒外(wai)(wai)，危(wei)害性(xing)(xing)(xing)能(neng)的(de)(de)(de)關鍵要素也(ye)(ye)有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)強(qiang)(qiang)度(du)、薄厚(hou)(hou)(hou)和(he)(he)永久性(xing)(xing)(xing)形(xing)(xing)變(bian)量。強(qiang)(qiang)度(du)和(he)(he)永久性(xing)(xing)(xing)形(xing)(xing)變(bian)量對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危(wei)害非常大。一(yi)般強(qiang)(qiang)度(du)高(gao)、縮(suo)小(xiao)后的(de)(de)(de)永久性(xing)(xing)(xing)形(xing)(xing)變(bian)量小(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好(hao)。一(yi)般是在(zai)(zai)７０～８５邵(shao)氏硬度(du)，縮(suo)小(xiao)永久性(xing)(xing)(xing)形(xing)(xing)變(bian)５０％時(shi)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄厚(hou)(hou)(hou)建議是為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會在(zai)(zai)壓(ya)(ya)扣(kou)時(shi)提升其流動率，導致不(bu)(bu)(bu)必(bi)要的(de)(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套與橡膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)(de)觸碰(peng)內(nei)(nei)孔(kong)內(nei)(nei)沉積，減少商(shang)品流通橫截面；過薄會在(zai)(zai)壓(ya)(ya)扣(kou)時(shi)被壓(ya)(ya)裂。另外(wai)(wai)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚(hou)(hou)(hou)勻(yun)稱性(xing)(xing)(xing)也(ye)(ye)很重(zhong)要。假如薄厚(hou)(hou)(hou)不(bu)(bu)(bu)勻(yun)，縮(suo)小(xiao)后會導致一(yi)面裂斷、一(yi)面堆(dui)膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出現(xian)的(de)(de)(de)浮銹(xiu)也(ye)(ye)是危(wei)害性(xing)(xing)(xing)能(neng)品質的(de)(de)(de)關鍵要素。
２）高壓(ya)膠管關鍵借助(zhu)提高層(ceng)(ceng)來承受力。手工(gong)編(bian)織橡膠軟管是(shi)(shi)靠膠漿與(yu)內外黏膠粘緊，因為同(tong)一(yi)(yi)手工(gong)編(bian)織層(ceng)(ceng)內不(bu)(bu)(bu)銹(xiu)鋼絲(si)中(zhong)(zhong)(zhong)間(jian)(jian)的(de)(de)互(hu)相(xiang)觸碰，在(zai)承擔氣體(ti)(ti)壓(ya)力的(de)(de)時候(hou)會因分別(bie)伸縮(suo)式不(bu)(bu)(bu)一(yi)(yi)而(er)導致不(bu)(bu)(bu)銹(xiu)鋼絲(si)彼此之間(jian)(jian)的(de)(de)摩擦而(er)危害其(qi)使(shi)用性能。而(er)螺旋波(bo)紋管是(shi)(shi)由盤繞方(fang)位(wei)不(bu)(bu)(bu)一(yi)(yi)樣的(de)(de)雙層(ceng)(ceng)產(chan)(chan)生一(yi)(yi)個工(gong)作中(zhong)(zhong)(zhong)層(ceng)(ceng)，在(zai)雙層(ceng)(ceng)中(zhong)(zhong)(zhong)間(jian)(jian)有正中(zhong)(zhong)(zhong)間(jian)(jian)膠，因而(er)同(tong)一(yi)(yi)工(gong)作中(zhong)(zhong)(zhong)層(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)不(bu)(bu)(bu)銹(xiu)鋼絲(si)中(zhong)(zhong)(zhong)間(jian)(jian)沒有交接點。因此 不(bu)(bu)(bu)容易在(zai)承擔氣體(ti)(ti)壓(ya)力時同(tong)于不(bu)(bu)(bu)銹(xiu)鋼絲(si)間(jian)(jian)的(de)(de)交叉式彎折而(er)產(chan)(chan)生應力或(huo)磨擦磨壞(huai)。故使(shi)用性能好，能承擔髙(gao)壓(ya)。
３）高壓膠(jiao)管的外膠(jiao)層(ceng)粘(zhan)在提高層(ceng)上起維護(hu)功效，一般選用氯(lv)丁膠(jiao)。應(ying)留意避免 其脆化開裂而危害全部橡膠(jiao)軟管的使用壽命。
