１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)層(ceng)(ceng)、提高層(ceng)(ceng)和外(wai)膠(jiao)(jiao)(jiao)層(ceng)(ceng)構成(cheng)（如(ru)圖例），內膠(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液(ye)壓(ya)油觸(chu)碰，故規(gui)定在(zai)長期性(xing)(xing)(xing)運行(xing)狀態下不可受(shou)液(ye)體浸(jin)蝕，能(neng)補漏(lou)。在(zai)提高層(ceng)(ceng)功效下會承擔一(yi)定工(gong)作壓(ya)力。因(yin)而，宜選用(yong)丁腈橡(xiang)(xiang)膠(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)粒外(wai)，危(wei)害性(xing)(xing)(xing)能(neng)的關鍵要(yao)(yao)素也(ye)有(you)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)的強(qiang)度(du)、薄(bo)厚(hou)和永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)(bian)量(liang)。強(qiang)度(du)和永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)(bian)量(liang)對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危(wei)害非(fei)常大(da)。一(yi)般強(qiang)度(du)高、縮小后(hou)的永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)(bian)量(liang)小，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則越好。一(yi)般是在(zai)７０～８５邵(shao)氏硬(ying)度(du)，縮小永久(jiu)(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變(bian)(bian)５０％時。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)建議是為(wei)１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)壓(ya)扣時提升其流動率，導致不必要(yao)(yao)的膠(jiao)(jiao)(jiao)在(zai)接頭芯套與橡(xiang)(xiang)膠(jiao)(jiao)(jiao)軟管的觸(chu)碰內孔內沉積，減少(shao)商品流通橫截(jie)面(mian)；過薄(bo)會在(zai)壓(ya)扣時被壓(ya)裂。另外(wai)內膠(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)也(ye)很重要(yao)(yao)。假如(ru)薄(bo)厚(hou)不勻，縮小后(hou)會導致一(yi)面(mian)裂斷(duan)、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現的浮銹也(ye)是危(wei)害性(xing)(xing)(xing)能(neng)品質的關鍵要(yao)(yao)素。
２）高壓膠(jiao)管(guan)關鍵借(jie)助提高層(ceng)(ceng)來(lai)承(cheng)受(shou)力。手工(gong)(gong)編(bian)(bian)織(zhi)橡膠(jiao)軟管(guan)是靠膠(jiao)漿(jiang)與內(nei)外黏膠(jiao)粘緊，因為同一(yi)(yi)手工(gong)(gong)編(bian)(bian)織(zhi)層(ceng)(ceng)內(nei)不(bu)銹鋼絲(si)(si)中(zhong)間(jian)的(de)(de)互相觸碰，在承(cheng)擔氣體壓力的(de)(de)時候會(hui)因分別伸縮(suo)式不(bu)一(yi)(yi)而(er)(er)(er)導致不(bu)銹鋼絲(si)(si)彼此之(zhi)間(jian)的(de)(de)摩(mo)擦而(er)(er)(er)危(wei)害其使(shi)用(yong)性能(neng)。而(er)(er)(er)螺旋波紋管(guan)是由盤繞方(fang)位(wei)不(bu)一(yi)(yi)樣的(de)(de)雙層(ceng)(ceng)產(chan)生(sheng)(sheng)一(yi)(yi)個工(gong)(gong)作中(zhong)層(ceng)(ceng)，在雙層(ceng)(ceng)中(zhong)間(jian)有正(zheng)中(zhong)間(jian)膠(jiao)，因而(er)(er)(er)同一(yi)(yi)工(gong)(gong)作中(zhong)層(ceng)(ceng)的(de)(de)雙層(ceng)(ceng)不(bu)銹鋼絲(si)(si)中(zhong)間(jian)沒有交(jiao)接點。因此 不(bu)容易在承(cheng)擔氣體壓力時同于不(bu)銹鋼絲(si)(si)間(jian)的(de)(de)交(jiao)叉式彎(wan)折(zhe)而(er)(er)(er)產(chan)生(sheng)(sheng)應(ying)力或(huo)磨擦磨壞。故使(shi)用(yong)性能(neng)好(hao)，能(neng)承(cheng)擔髙壓。
３）高壓膠管的外膠層粘在提(ti)高層上起維護(hu)功效(xiao)，一般選(xuan)用氯丁膠。應(ying)留(liu)意(yi)避免 其脆化開(kai)裂而危害全部橡膠軟管的使用壽命。
