１、橡膠軟管總成
1）高壓膠(jiao)管(guan)由內(nei)膠(jiao)層(ceng)(ceng)、提高層(ceng)(ceng)和(he)(he)外(wai)膠(jiao)層(ceng)(ceng)構成（如圖例(li)），內(nei)膠(jiao)層(ceng)(ceng)立即與(yu)液壓油(you)觸碰，故規(gui)定在(zai)(zai)長期性(xing)(xing)(xing)運行狀(zhuang)態(tai)下不(bu)可受液體浸蝕，能(neng)補漏。在(zai)(zai)提高層(ceng)(ceng)功效下會承擔一(yi)定工作壓力。因而，宜選用丁(ding)腈(jing)橡膠(jiao)，除塑膠(jiao)粒外(wai)，危害(hai)性(xing)(xing)(xing)能(neng)的(de)(de)關鍵要(yao)素(su)(su)也(ye)有(you)內(nei)膠(jiao)層(ceng)(ceng)的(de)(de)強(qiang)度(du)、薄厚(hou)和(he)(he)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)變(bian)(bian)量。強(qiang)度(du)和(he)(he)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)變(bian)(bian)量對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危害(hai)非常大。一(yi)般強(qiang)度(du)高、縮小后(hou)(hou)的(de)(de)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)變(bian)(bian)量小，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則(ze)越好。一(yi)般是(shi)(shi)在(zai)(zai)７０～８５邵氏硬度(du)，縮小永(yong)久(jiu)性(xing)(xing)(xing)形(xing)變(bian)(bian)５０％時(shi)(shi)(shi)。內(nei)膠(jiao)層(ceng)(ceng)薄厚(hou)建(jian)議(yi)是(shi)(shi)為１．５～２．５ｍｍ，太厚(hou)會在(zai)(zai)壓扣(kou)時(shi)(shi)(shi)提升其(qi)流(liu)動率(lv)，導致(zhi)不(bu)必(bi)要(yao)的(de)(de)膠(jiao)在(zai)(zai)接頭芯(xin)套與(yu)橡膠(jiao)軟(ruan)管(guan)的(de)(de)觸碰內(nei)孔(kong)內(nei)沉積，減少商品(pin)流(liu)通(tong)橫截面(mian)(mian)；過(guo)薄會在(zai)(zai)壓扣(kou)時(shi)(shi)(shi)被壓裂。另(ling)外(wai)內(nei)膠(jiao)層(ceng)(ceng)壁厚(hou)勻(yun)稱(cheng)性(xing)(xing)(xing)也(ye)很重要(yao)。假如薄厚(hou)不(bu)勻(yun)，縮小后(hou)(hou)會導致(zhi)一(yi)面(mian)(mian)裂斷、一(yi)面(mian)(mian)堆膠(jiao)。內(nei)膠(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的(de)(de)浮銹(xiu)也(ye)是(shi)(shi)危害(hai)性(xing)(xing)(xing)能(neng)品(pin)質的(de)(de)關鍵要(yao)素(su)(su)。
２）高壓膠(jiao)管關鍵借助提高層(ceng)來(lai)承(cheng)(cheng)受(shou)力。手工(gong)(gong)編織(zhi)橡膠(jiao)軟管是靠(kao)膠(jiao)漿與內外黏膠(jiao)粘緊，因(yin)為同一手工(gong)(gong)編織(zhi)層(ceng)內不(bu)銹鋼絲中(zhong)間(jian)的(de)互相觸碰，在承(cheng)(cheng)擔(dan)氣體壓力的(de)時候會因(yin)分別伸縮式不(bu)一而(er)導致(zhi)不(bu)銹鋼絲彼此之(zhi)間(jian)的(de)摩擦而(er)危害(hai)其使(shi)用(yong)性能(neng)。而(er)螺旋波紋管是由盤繞方位(wei)不(bu)一樣的(de)雙層(ceng)產(chan)生(sheng)一個工(gong)(gong)作(zuo)中(zhong)層(ceng)，在雙層(ceng)中(zhong)間(jian)有正中(zhong)間(jian)膠(jiao)，因(yin)而(er)同一工(gong)(gong)作(zuo)中(zhong)層(ceng)的(de)雙層(ceng)不(bu)銹鋼絲中(zhong)間(jian)沒有交(jiao)接點(dian)。因(yin)此 不(bu)容(rong)易(yi)在承(cheng)(cheng)擔(dan)氣體壓力時同于(yu)不(bu)銹鋼絲間(jian)的(de)交(jiao)叉式彎(wan)折而(er)產(chan)生(sheng)應(ying)力或(huo)磨擦磨壞。故(gu)使(shi)用(yong)性能(neng)好，能(neng)承(cheng)(cheng)擔(dan)髙(gao)壓。
３）高(gao)壓膠(jiao)(jiao)管的外(wai)膠(jiao)(jiao)層(ceng)粘在提高(gao)層(ceng)上起(qi)維護(hu)功(gong)效，一般選用氯丁膠(jiao)(jiao)。應(ying)留意避免 其(qi)脆化(hua)開(kai)裂(lie)而危害全部橡膠(jiao)(jiao)軟管的使用壽命(ming)。
