１、橡膠軟管總成
1）高(gao)(gao)壓(ya)膠(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)層(ceng)、提(ti)高(gao)(gao)層(ceng)和外(wai)膠(jiao)(jiao)(jiao)層(ceng)構成（如(ru)圖例），內(nei)膠(jiao)(jiao)(jiao)層(ceng)立即與(yu)液壓(ya)油觸碰(peng)(peng)，故規定在(zai)長期性(xing)(xing)運(yun)行狀(zhuang)態下(xia)不可受(shou)液體浸蝕，能(neng)補(bu)漏。在(zai)提(ti)高(gao)(gao)層(ceng)功效下(xia)會(hui)承擔一定工作(zuo)壓(ya)力(li)。因(yin)而，宜選用丁(ding)腈橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外(wai)，危(wei)害(hai)性(xing)(xing)能(neng)的關鍵(jian)要(yao)(yao)素也有(you)內(nei)膠(jiao)(jiao)(jiao)層(ceng)的強度、薄厚和永久性(xing)(xing)形(xing)(xing)(xing)變量。強度和永久性(xing)(xing)形(xing)(xing)(xing)變量對密封性(xing)(xing)性(xing)(xing)能(neng)危(wei)害(hai)非常(chang)大(da)。一般強度高(gao)(gao)、縮小(xiao)后(hou)的永久性(xing)(xing)形(xing)(xing)(xing)變量小(xiao)，密封性(xing)(xing)性(xing)(xing)能(neng)則(ze)越好。一般是在(zai)７０～８５邵氏硬度，縮小(xiao)永久性(xing)(xing)形(xing)(xing)(xing)變５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)薄厚建議是為(wei)１．５～２．５ｍｍ，太(tai)厚會(hui)在(zai)壓(ya)扣時(shi)提(ti)升其流動率，導致(zhi)不必要(yao)(yao)的膠(jiao)(jiao)(jiao)在(zai)接(jie)頭芯套與(yu)橡膠(jiao)(jiao)(jiao)軟(ruan)管的觸碰(peng)(peng)內(nei)孔內(nei)沉積，減少商品(pin)流通橫截面(mian)(mian)；過薄會(hui)在(zai)壓(ya)扣時(shi)被壓(ya)裂。另(ling)外(wai)內(nei)膠(jiao)(jiao)(jiao)層(ceng)壁厚勻稱(cheng)性(xing)(xing)也很重要(yao)(yao)。假如(ru)薄厚不勻，縮小(xiao)后(hou)會(hui)導致(zhi)一面(mian)(mian)裂斷、一面(mian)(mian)堆(dui)膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層(ceng)表(biao)層(ceng)出現的浮銹也是危(wei)害(hai)性(xing)(xing)能(neng)品(pin)質的關鍵(jian)要(yao)(yao)素。
２）高(gao)壓膠管(guan)關鍵借助(zhu)提高(gao)層(ceng)(ceng)(ceng)(ceng)來承受(shou)力(li)。手(shou)工(gong)編織(zhi)橡膠軟管(guan)是靠膠漿與內外黏膠粘緊，因(yin)(yin)為同(tong)一(yi)(yi)手(shou)工(gong)編織(zhi)層(ceng)(ceng)(ceng)(ceng)內不銹鋼(gang)(gang)(gang)絲(si)(si)中(zhong)(zhong)間的互相觸碰(peng)，在(zai)承擔氣(qi)體壓力(li)的時(shi)候會因(yin)(yin)分別(bie)伸縮式不一(yi)(yi)而(er)(er)導致不銹鋼(gang)(gang)(gang)絲(si)(si)彼此(ci)之間的摩擦(ca)而(er)(er)危害其(qi)使用(yong)性(xing)能。而(er)(er)螺旋(xuan)波紋管(guan)是由(you)盤繞方位不一(yi)(yi)樣的雙層(ceng)(ceng)(ceng)(ceng)產生(sheng)一(yi)(yi)個工(gong)作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，在(zai)雙層(ceng)(ceng)(ceng)(ceng)中(zhong)(zhong)間有(you)正中(zhong)(zhong)間膠，因(yin)(yin)而(er)(er)同(tong)一(yi)(yi)工(gong)作(zuo)中(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)的雙層(ceng)(ceng)(ceng)(ceng)不銹鋼(gang)(gang)(gang)絲(si)(si)中(zhong)(zhong)間沒(mei)有(you)交(jiao)接點。因(yin)(yin)此(ci) 不容(rong)易在(zai)承擔氣(qi)體壓力(li)時(shi)同(tong)于不銹鋼(gang)(gang)(gang)絲(si)(si)間的交(jiao)叉式彎(wan)折而(er)(er)產生(sheng)應力(li)或磨(mo)擦(ca)磨(mo)壞。故使用(yong)性(xing)能好，能承擔髙壓。
３）高壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層粘(zhan)在提高層上起維(wei)護功(gong)效，一般選用(yong)氯(lv)丁(ding)膠(jiao)(jiao)。應留(liu)意避(bi)免 其脆化開裂而危害全部橡膠(jiao)(jiao)軟(ruan)管的使用(yong)壽(shou)命。
