１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)管由內(nei)膠(jiao)層(ceng)、提高(gao)層(ceng)和外膠(jiao)層(ceng)構成（如(ru)圖例(li)），內(nei)膠(jiao)層(ceng)立即與(yu)液(ye)壓(ya)(ya)油觸碰，故規(gui)定在(zai)(zai)長期(qi)性(xing)(xing)(xing)(xing)運行狀(zhuang)態下不可受液(ye)體浸蝕，能(neng)補漏。在(zai)(zai)提高(gao)層(ceng)功效下會(hui)承擔(dan)一定工作壓(ya)(ya)力。因(yin)而，宜選用丁(ding)腈橡(xiang)膠(jiao)，除塑膠(jiao)粒(li)外，危害(hai)性(xing)(xing)(xing)(xing)能(neng)的關鍵要素(su)(su)也有內(nei)膠(jiao)層(ceng)的強度、薄(bo)厚和永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)變量。強度和永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)變量對密(mi)封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)危害(hai)非常(chang)大。一般強度高(gao)、縮(suo)小后的永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)變量小，密(mi)封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)則(ze)越好。一般是在(zai)(zai)７０～８５邵(shao)氏(shi)硬度，縮(suo)小永(yong)久(jiu)性(xing)(xing)(xing)(xing)形(xing)變５０％時(shi)(shi)(shi)。內(nei)膠(jiao)層(ceng)薄(bo)厚建(jian)議是為１．５～２．５ｍｍ，太厚會(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)(shi)(shi)提升其(qi)流動率，導致不必(bi)要的膠(jiao)在(zai)(zai)接(jie)頭芯套與(yu)橡(xiang)膠(jiao)軟(ruan)管的觸碰內(nei)孔(kong)內(nei)沉積，減少商(shang)品流通(tong)橫截面(mian)；過薄(bo)會(hui)在(zai)(zai)壓(ya)(ya)扣時(shi)(shi)(shi)被壓(ya)(ya)裂。另(ling)外內(nei)膠(jiao)層(ceng)壁厚勻(yun)(yun)稱性(xing)(xing)(xing)(xing)也很重要。假如(ru)薄(bo)厚不勻(yun)(yun)，縮(suo)小后會(hui)導致一面(mian)裂斷、一面(mian)堆膠(jiao)。內(nei)膠(jiao)層(ceng)表層(ceng)出現的浮銹也是危害(hai)性(xing)(xing)(xing)(xing)能(neng)品質的關鍵要素(su)(su)。
２）高壓(ya)(ya)(ya)膠管關鍵借助提高層(ceng)來(lai)承(cheng)受(shou)力。手(shou)工(gong)(gong)編(bian)織(zhi)橡膠軟管是靠膠漿與內外黏(nian)膠粘緊，因(yin)為同一(yi)手(shou)工(gong)(gong)編(bian)織(zhi)層(ceng)內不(bu)銹鋼絲(si)(si)中間(jian)(jian)(jian)的(de)互相觸碰(peng)，在承(cheng)擔氣體壓(ya)(ya)(ya)力的(de)時候會因(yin)分別伸縮式不(bu)一(yi)而(er)導(dao)致不(bu)銹鋼絲(si)(si)彼此之(zhi)間(jian)(jian)(jian)的(de)摩擦(ca)而(er)危害其使用性(xing)能(neng)。而(er)螺(luo)旋(xuan)波(bo)紋管是由盤繞方位不(bu)一(yi)樣的(de)雙(shuang)(shuang)層(ceng)產生(sheng)一(yi)個工(gong)(gong)作中層(ceng)，在雙(shuang)(shuang)層(ceng)中間(jian)(jian)(jian)有正(zheng)中間(jian)(jian)(jian)膠，因(yin)而(er)同一(yi)工(gong)(gong)作中層(ceng)的(de)雙(shuang)(shuang)層(ceng)不(bu)銹鋼絲(si)(si)中間(jian)(jian)(jian)沒有交(jiao)接點(dian)。因(yin)此 不(bu)容易在承(cheng)擔氣體壓(ya)(ya)(ya)力時同于不(bu)銹鋼絲(si)(si)間(jian)(jian)(jian)的(de)交(jiao)叉式彎折(zhe)而(er)產生(sheng)應力或(huo)磨擦(ca)磨壞(huai)。故使用性(xing)能(neng)好(hao)，能(neng)承(cheng)擔髙(gao)壓(ya)(ya)(ya)。
３）高(gao)壓膠管(guan)的外膠層粘(zhan)在提高(gao)層上起維護功效，一(yi)般選用(yong)氯丁膠。應(ying)留(liu)意避免 其脆化開裂(lie)而危(wei)害全部橡膠軟管(guan)的使(shi)用(yong)壽(shou)命(ming)。
