１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)管(guan)由內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提(ti)(ti)高(gao)層(ceng)(ceng)(ceng)(ceng)和外膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立(li)即與(yu)液(ye)壓(ya)(ya)油觸碰，故規定在(zai)長期性(xing)(xing)(xing)運(yun)行(xing)狀態下不(bu)(bu)可受液(ye)體浸蝕，能(neng)補漏。在(zai)提(ti)(ti)高(gao)層(ceng)(ceng)(ceng)(ceng)功效(xiao)下會(hui)(hui)承擔一(yi)定工作壓(ya)(ya)力。因而(er)，宜選用(yong)丁(ding)腈(jing)橡(xiang)(xiang)膠(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)粒外，危(wei)害性(xing)(xing)(xing)能(neng)的(de)(de)關鍵要(yao)素(su)也有內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)(de)強度、薄厚和永久(jiu)性(xing)(xing)(xing)形(xing)變量。強度和永久(jiu)性(xing)(xing)(xing)形(xing)變量對密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危(wei)害非常大(da)。一(yi)般強度高(gao)、縮小后(hou)的(de)(de)永久(jiu)性(xing)(xing)(xing)形(xing)變量小，密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好(hao)。一(yi)般是(shi)在(zai)７０～８５邵氏硬度，縮小永久(jiu)性(xing)(xing)(xing)形(xing)變５０％時。內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄厚建(jian)議(yi)是(shi)為１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)壓(ya)(ya)扣(kou)時提(ti)(ti)升其流動(dong)率(lv)，導致不(bu)(bu)必要(yao)的(de)(de)膠(jiao)(jiao)在(zai)接頭(tou)芯套與(yu)橡(xiang)(xiang)膠(jiao)(jiao)軟(ruan)管(guan)的(de)(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積(ji)，減(jian)少商品流通橫截面(mian)；過薄會(hui)(hui)在(zai)壓(ya)(ya)扣(kou)時被壓(ya)(ya)裂。另外內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚勻(yun)稱性(xing)(xing)(xing)也很重要(yao)。假如薄厚不(bu)(bu)勻(yun)，縮小后(hou)會(hui)(hui)導致一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出現的(de)(de)浮銹也是(shi)危(wei)害性(xing)(xing)(xing)能(neng)品質(zhi)的(de)(de)關鍵要(yao)素(su)。
２）高(gao)壓膠(jiao)(jiao)管關(guan)鍵借(jie)助(zhu)提高(gao)層(ceng)(ceng)來(lai)承受力。手工(gong)編(bian)(bian)織橡膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿(jiang)與內(nei)外黏膠(jiao)(jiao)粘緊，因為同(tong)一(yi)(yi)手工(gong)編(bian)(bian)織層(ceng)(ceng)內(nei)不(bu)銹鋼絲(si)中(zhong)(zhong)間(jian)的互(hu)相觸碰(peng)，在(zai)承擔氣(qi)體壓力的時(shi)候會(hui)因分別伸縮式不(bu)一(yi)(yi)而導致不(bu)銹鋼絲(si)彼此之間(jian)的摩擦而危害其使用性能。而螺旋波紋(wen)管是由盤(pan)繞(rao)方位(wei)不(bu)一(yi)(yi)樣的雙(shuang)層(ceng)(ceng)產(chan)生一(yi)(yi)個工(gong)作中(zhong)(zhong)層(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)中(zhong)(zhong)間(jian)有(you)正中(zhong)(zhong)間(jian)膠(jiao)(jiao)，因而同(tong)一(yi)(yi)工(gong)作中(zhong)(zhong)層(ceng)(ceng)的雙(shuang)層(ceng)(ceng)不(bu)銹鋼絲(si)中(zhong)(zhong)間(jian)沒(mei)有(you)交接點。因此 不(bu)容易在(zai)承擔氣(qi)體壓力時(shi)同(tong)于不(bu)銹鋼絲(si)間(jian)的交叉式彎(wan)折而產(chan)生應(ying)力或磨擦磨壞。故(gu)使用性能好，能承擔髙壓。
３）高壓膠(jiao)管的外(wai)膠(jiao)層粘在提高層上(shang)起維(wei)護功效，一般選用(yong)氯丁膠(jiao)。應留意避(bi)免 其脆化開裂(lie)而危害(hai)全部(bu)橡膠(jiao)軟管的使用(yong)壽命。
