１、橡膠軟管總成
1）高壓(ya)(ya)(ya)膠(jiao)(jiao)管由內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)(ti)高層(ceng)(ceng)(ceng)和外(wai)膠(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如(ru)(ru)圖例），內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)立(li)即與液壓(ya)(ya)(ya)油觸碰，故規定在(zai)(zai)(zai)長期(qi)性運(yun)行狀(zhuang)態(tai)下(xia)不(bu)可受液體浸蝕，能補漏。在(zai)(zai)(zai)提(ti)(ti)高層(ceng)(ceng)(ceng)功效下(xia)會承擔一(yi)定工作壓(ya)(ya)(ya)力。因(yin)而，宜選用丁腈橡(xiang)(xiang)膠(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)粒(li)外(wai)，危(wei)害性能的關(guan)鍵(jian)要(yao)素(su)(su)也有內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)的強(qiang)度、薄(bo)厚和永(yong)久(jiu)性形(xing)(xing)變(bian)量(liang)。強(qiang)度和永(yong)久(jiu)性形(xing)(xing)變(bian)量(liang)對密封性性能危(wei)害非(fei)常(chang)大。一(yi)般強(qiang)度高、縮小(xiao)(xiao)后(hou)的永(yong)久(jiu)性形(xing)(xing)變(bian)量(liang)小(xiao)(xiao)，密封性性能則越好。一(yi)般是在(zai)(zai)(zai)７０～８５邵(shao)氏(shi)硬(ying)度，縮小(xiao)(xiao)永(yong)久(jiu)性形(xing)(xing)變(bian)５０％時。內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建議是為１．５～２．５ｍｍ，太厚會在(zai)(zai)(zai)壓(ya)(ya)(ya)扣(kou)時提(ti)(ti)升其流動(dong)率，導(dao)致(zhi)不(bu)必要(yao)的膠(jiao)(jiao)在(zai)(zai)(zai)接(jie)頭(tou)芯套與橡(xiang)(xiang)膠(jiao)(jiao)軟管的觸碰內(nei)孔(kong)內(nei)沉積(ji)，減少商品(pin)流通(tong)橫(heng)截(jie)面(mian)；過薄(bo)會在(zai)(zai)(zai)壓(ya)(ya)(ya)扣(kou)時被(bei)壓(ya)(ya)(ya)裂(lie)。另外(wai)內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻(yun)稱性也很重(zhong)要(yao)。假如(ru)(ru)薄(bo)厚不(bu)勻(yun)，縮小(xiao)(xiao)后(hou)會導(dao)致(zhi)一(yi)面(mian)裂(lie)斷(duan)、一(yi)面(mian)堆(dui)膠(jiao)(jiao)。內(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的浮銹也是危(wei)害性能品(pin)質的關(guan)鍵(jian)要(yao)素(su)(su)。
２）高(gao)壓(ya)(ya)膠(jiao)管(guan)(guan)關鍵借(jie)助提高(gao)層(ceng)來(lai)承(cheng)受力(li)。手(shou)工編織橡膠(jiao)軟(ruan)管(guan)(guan)是靠膠(jiao)漿與(yu)內外黏膠(jiao)粘緊，因(yin)為同(tong)(tong)一(yi)手(shou)工編織層(ceng)內不(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間的(de)互相觸碰，在承(cheng)擔氣體壓(ya)(ya)力(li)的(de)時候會(hui)因(yin)分別伸縮式不(bu)一(yi)而導致不(bu)銹鋼(gang)絲(si)彼此(ci)之間的(de)摩(mo)擦而危害其(qi)使用(yong)(yong)性(xing)能(neng)。而螺旋波(bo)紋管(guan)(guan)是由盤繞方(fang)位(wei)不(bu)一(yi)樣的(de)雙(shuang)(shuang)層(ceng)產生(sheng)一(yi)個工作中(zhong)(zhong)層(ceng)，在雙(shuang)(shuang)層(ceng)中(zhong)(zhong)間有正中(zhong)(zhong)間膠(jiao)，因(yin)而同(tong)(tong)一(yi)工作中(zhong)(zhong)層(ceng)的(de)雙(shuang)(shuang)層(ceng)不(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間沒有交(jiao)接點。因(yin)此(ci) 不(bu)容易在承(cheng)擔氣體壓(ya)(ya)力(li)時同(tong)(tong)于不(bu)銹鋼(gang)絲(si)間的(de)交(jiao)叉式彎折(zhe)而產生(sheng)應(ying)力(li)或(huo)磨擦磨壞。故使用(yong)(yong)性(xing)能(neng)好(hao)，能(neng)承(cheng)擔髙壓(ya)(ya)。
３）高壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層粘在(zai)提高層上(shang)起維護功效(xiao)，一般(ban)選用(yong)氯丁膠(jiao)(jiao)。應(ying)留意避免(mian) 其脆化開裂而(er)危(wei)害全部橡膠(jiao)(jiao)軟管的使用(yong)壽(shou)命。
