１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由(you)內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)、提高(gao)層(ceng)和(he)(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)構成(cheng)（如圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)立即(ji)與(yu)液(ye)壓(ya)油觸碰，故規(gui)定在長期性(xing)(xing)(xing)運行狀態(tai)下不可(ke)受液(ye)體浸蝕(shi)，能(neng)(neng)(neng)補漏。在提高(gao)層(ceng)功效(xiao)下會承擔一(yi)定工作(zuo)壓(ya)力(li)。因而，宜選用丁腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危害性(xing)(xing)(xing)能(neng)(neng)(neng)的關鍵(jian)要(yao)素(su)也(ye)有內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)的強度(du)、薄(bo)厚和(he)(he)永(yong)久性(xing)(xing)(xing)形(xing)(xing)變(bian)量。強度(du)和(he)(he)永(yong)久性(xing)(xing)(xing)形(xing)(xing)變(bian)量對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)(neng)危害非常大(da)。一(yi)般(ban)強度(du)高(gao)、縮小(xiao)(xiao)后的永(yong)久性(xing)(xing)(xing)形(xing)(xing)變(bian)量小(xiao)(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)(neng)(neng)則越(yue)好。一(yi)般(ban)是在７０～８５邵氏硬度(du)，縮小(xiao)(xiao)永(yong)久性(xing)(xing)(xing)形(xing)(xing)變(bian)５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)薄(bo)厚建議(yi)是為１．５～２．５ｍｍ，太厚會在壓(ya)扣時(shi)提升其流動率(lv)，導(dao)致(zhi)不必(bi)要(yao)的膠(jiao)(jiao)(jiao)(jiao)在接頭(tou)芯套與(yu)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟管的觸碰內(nei)孔內(nei)沉積，減少商品流通(tong)橫截面(mian)；過薄(bo)會在壓(ya)扣時(shi)被壓(ya)裂。另外內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚勻(yun)稱性(xing)(xing)(xing)也(ye)很重要(yao)。假(jia)如薄(bo)厚不勻(yun)，縮小(xiao)(xiao)后會導(dao)致(zhi)一(yi)面(mian)裂斷、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)表層(ceng)出現的浮銹(xiu)也(ye)是危害性(xing)(xing)(xing)能(neng)(neng)(neng)品質的關鍵(jian)要(yao)素(su)。
２）高壓(ya)(ya)膠(jiao)管關(guan)鍵(jian)借助提高層(ceng)來承(cheng)受力。手工(gong)(gong)編織橡膠(jiao)軟(ruan)管是靠膠(jiao)漿與(yu)內(nei)(nei)外(wai)黏膠(jiao)粘緊，因(yin)(yin)為(wei)同(tong)一(yi)手工(gong)(gong)編織層(ceng)內(nei)(nei)不(bu)(bu)(bu)銹(xiu)鋼絲中(zhong)(zhong)間的(de)互相觸碰(peng)，在(zai)(zai)承(cheng)擔氣(qi)體壓(ya)(ya)力的(de)時(shi)(shi)候會因(yin)(yin)分(fen)別伸縮(suo)式不(bu)(bu)(bu)一(yi)而(er)(er)(er)導致(zhi)不(bu)(bu)(bu)銹(xiu)鋼絲彼(bi)此(ci)之(zhi)間的(de)摩擦而(er)(er)(er)危(wei)害(hai)其使用(yong)性能(neng)。而(er)(er)(er)螺(luo)旋波紋(wen)管是由盤繞方位不(bu)(bu)(bu)一(yi)樣的(de)雙層(ceng)產生一(yi)個(ge)工(gong)(gong)作中(zhong)(zhong)層(ceng)，在(zai)(zai)雙層(ceng)中(zhong)(zhong)間有正中(zhong)(zhong)間膠(jiao)，因(yin)(yin)而(er)(er)(er)同(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)層(ceng)的(de)雙層(ceng)不(bu)(bu)(bu)銹(xiu)鋼絲中(zhong)(zhong)間沒有交(jiao)接(jie)點。因(yin)(yin)此(ci) 不(bu)(bu)(bu)容易在(zai)(zai)承(cheng)擔氣(qi)體壓(ya)(ya)力時(shi)(shi)同(tong)于不(bu)(bu)(bu)銹(xiu)鋼絲間的(de)交(jiao)叉式彎(wan)折而(er)(er)(er)產生應(ying)力或磨(mo)(mo)擦磨(mo)(mo)壞。故使用(yong)性能(neng)好，能(neng)承(cheng)擔髙壓(ya)(ya)。
３）高(gao)壓膠管的(de)外膠層(ceng)粘在提高(gao)層(ceng)上起維護功效(xiao)，一般選用氯丁(ding)膠。應留意避免 其脆化開(kai)裂而危(wei)害全部橡膠軟管的(de)使用壽(shou)命。
