１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高層(ceng)(ceng)(ceng)和(he)(he)外膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即與(yu)液壓(ya)油觸碰，故規定在長期性(xing)運行狀(zhuang)態下(xia)不可受液體(ti)浸蝕，能(neng)(neng)補漏。在提高層(ceng)(ceng)(ceng)功效下(xia)會承擔一(yi)定工作壓(ya)力。因而，宜(yi)選用丁(ding)腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒外，危害(hai)性(xing)能(neng)(neng)的(de)關(guan)鍵要(yao)(yao)(yao)(yao)素也(ye)有內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強度、薄(bo)厚(hou)和(he)(he)永久(jiu)(jiu)性(xing)形變(bian)量(liang)。強度和(he)(he)永久(jiu)(jiu)性(xing)形變(bian)量(liang)對密封(feng)性(xing)性(xing)能(neng)(neng)危害(hai)非常大。一(yi)般(ban)(ban)強度高、縮(suo)小(xiao)后的(de)永久(jiu)(jiu)性(xing)形變(bian)量(liang)小(xiao)，密封(feng)性(xing)性(xing)能(neng)(neng)則越(yue)好。一(yi)般(ban)(ban)是在７０～８５邵氏(shi)硬(ying)度，縮(suo)小(xiao)永久(jiu)(jiu)性(xing)形變(bian)５０％時。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚(hou)建議是為１．５～２．５ｍｍ，太厚(hou)會在壓(ya)扣時提升其流(liu)(liu)動率，導致不必要(yao)(yao)(yao)(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在接(jie)頭芯套與(yu)橡膠(jiao)(jiao)(jiao)(jiao)(jiao)軟(ruan)管的(de)觸碰內(nei)(nei)孔內(nei)(nei)沉積，減少商品(pin)流(liu)(liu)通(tong)橫(heng)截面；過薄(bo)會在壓(ya)扣時被壓(ya)裂。另外內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁(bi)厚(hou)勻(yun)稱性(xing)也(ye)很重要(yao)(yao)(yao)(yao)。假如薄(bo)厚(hou)不勻(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)表層(ceng)(ceng)(ceng)出(chu)現的(de)浮銹也(ye)是危害(hai)性(xing)能(neng)(neng)品(pin)質的(de)關(guan)鍵要(yao)(yao)(yao)(yao)素。
２）高(gao)壓(ya)膠(jiao)(jiao)管關鍵(jian)借助(zhu)提高(gao)層(ceng)(ceng)(ceng)來(lai)承(cheng)(cheng)受(shou)力。手工(gong)(gong)編(bian)織橡膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與(yu)內外(wai)黏膠(jiao)(jiao)粘緊，因(yin)(yin)(yin)為同一手工(gong)(gong)編(bian)織層(ceng)(ceng)(ceng)內不銹(xiu)鋼(gang)(gang)絲(si)(si)中(zhong)(zhong)間(jian)(jian)的互(hu)相觸碰，在(zai)承(cheng)(cheng)擔(dan)氣(qi)體壓(ya)力的時候(hou)會因(yin)(yin)(yin)分別伸縮式(shi)不一而(er)(er)導致(zhi)不銹(xiu)鋼(gang)(gang)絲(si)(si)彼此之間(jian)(jian)的摩擦(ca)而(er)(er)危害其使用性能。而(er)(er)螺旋波紋管是由盤(pan)繞方位(wei)不一樣的雙(shuang)層(ceng)(ceng)(ceng)產(chan)生一個工(gong)(gong)作中(zhong)(zhong)層(ceng)(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)有正中(zhong)(zhong)間(jian)(jian)膠(jiao)(jiao)，因(yin)(yin)(yin)而(er)(er)同一工(gong)(gong)作中(zhong)(zhong)層(ceng)(ceng)(ceng)的雙(shuang)層(ceng)(ceng)(ceng)不銹(xiu)鋼(gang)(gang)絲(si)(si)中(zhong)(zhong)間(jian)(jian)沒有交接點(dian)。因(yin)(yin)(yin)此 不容易(yi)在(zai)承(cheng)(cheng)擔(dan)氣(qi)體壓(ya)力時同于不銹(xiu)鋼(gang)(gang)絲(si)(si)間(jian)(jian)的交叉式(shi)彎折而(er)(er)產(chan)生應力或磨(mo)擦(ca)磨(mo)壞。故使用性能好，能承(cheng)(cheng)擔(dan)髙壓(ya)。
３）高壓(ya)膠(jiao)管的(de)外膠(jiao)層粘在(zai)提高層上起(qi)維護功(gong)效，一般選用(yong)氯丁膠(jiao)。應(ying)留意避免 其脆化開裂而(er)危(wei)害全(quan)部橡膠(jiao)軟管的(de)使用(yong)壽命。
