１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)管由內(nei)膠(jiao)層(ceng)(ceng)、提高(gao)層(ceng)(ceng)和外膠(jiao)層(ceng)(ceng)構成（如圖例），內(nei)膠(jiao)層(ceng)(ceng)立即與液(ye)壓(ya)油觸碰，故規定在(zai)長期性(xing)(xing)(xing)運行狀態下(xia)不(bu)可受液(ye)體浸蝕，能(neng)補漏。在(zai)提高(gao)層(ceng)(ceng)功效下(xia)會承擔一定工作壓(ya)力。因而，宜選(xuan)用丁腈橡膠(jiao)，除塑膠(jiao)粒外，危害性(xing)(xing)(xing)能(neng)的(de)關鍵要素(su)也有內(nei)膠(jiao)層(ceng)(ceng)的(de)強度(du)、薄厚(hou)(hou)(hou)和永久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量。強度(du)和永久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量對(dui)密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害非常(chang)大。一般強度(du)高(gao)、縮(suo)小(xiao)后的(de)永久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)量小(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則(ze)越(yue)好。一般是(shi)(shi)在(zai)７０～８５邵(shao)氏硬度(du)，縮(suo)小(xiao)永久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)５０％時。內(nei)膠(jiao)層(ceng)(ceng)薄厚(hou)(hou)(hou)建議是(shi)(shi)為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會在(zai)壓(ya)扣時提升其(qi)流動(dong)率，導致(zhi)不(bu)必要的(de)膠(jiao)在(zai)接(jie)頭芯(xin)套與橡膠(jiao)軟管的(de)觸碰內(nei)孔(kong)內(nei)沉積，減少商品(pin)流通橫截面；過薄會在(zai)壓(ya)扣時被壓(ya)裂。另外內(nei)膠(jiao)層(ceng)(ceng)壁厚(hou)(hou)(hou)勻稱(cheng)性(xing)(xing)(xing)也很(hen)重要。假如薄厚(hou)(hou)(hou)不(bu)勻，縮(suo)小(xiao)后會導致(zhi)一面裂斷、一面堆(dui)膠(jiao)。內(nei)膠(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現(xian)的(de)浮銹(xiu)也是(shi)(shi)危害性(xing)(xing)(xing)能(neng)品(pin)質(zhi)的(de)關鍵要素(su)。
２）高壓(ya)膠(jiao)管(guan)關鍵(jian)借助提(ti)高層來承(cheng)(cheng)受力(li)。手工(gong)編(bian)織(zhi)(zhi)橡膠(jiao)軟管(guan)是(shi)靠膠(jiao)漿與(yu)內外(wai)黏(nian)膠(jiao)粘緊(jin)，因(yin)(yin)為同(tong)(tong)一手工(gong)編(bian)織(zhi)(zhi)層內不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)中(zhong)(zhong)間(jian)的(de)互相(xiang)觸碰，在(zai)承(cheng)(cheng)擔(dan)(dan)氣體壓(ya)力(li)的(de)時(shi)候會因(yin)(yin)分別伸縮式不(bu)(bu)(bu)(bu)一而(er)導致不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)彼此(ci)之間(jian)的(de)摩(mo)擦(ca)而(er)危害其使用性(xing)能(neng)。而(er)螺旋波紋(wen)管(guan)是(shi)由盤繞方位不(bu)(bu)(bu)(bu)一樣(yang)的(de)雙層產生一個工(gong)作中(zhong)(zhong)層，在(zai)雙層中(zhong)(zhong)間(jian)有(you)正中(zhong)(zhong)間(jian)膠(jiao)，因(yin)(yin)而(er)同(tong)(tong)一工(gong)作中(zhong)(zhong)層的(de)雙層不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)中(zhong)(zhong)間(jian)沒有(you)交接(jie)點。因(yin)(yin)此(ci) 不(bu)(bu)(bu)(bu)容易在(zai)承(cheng)(cheng)擔(dan)(dan)氣體壓(ya)力(li)時(shi)同(tong)(tong)于不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)絲(si)間(jian)的(de)交叉式彎折而(er)產生應(ying)力(li)或磨(mo)擦(ca)磨(mo)壞。故使用性(xing)能(neng)好，能(neng)承(cheng)(cheng)擔(dan)(dan)髙壓(ya)。
３）高(gao)壓膠管(guan)的(de)外膠層(ceng)粘(zhan)在提高(gao)層(ceng)上起(qi)維護功效，一般選用(yong)氯丁膠。應留(liu)意(yi)避免 其脆化(hua)開裂而危害(hai)全部(bu)橡膠軟管(guan)的(de)使用(yong)壽命(ming)。
