１、橡膠軟管總成
1）高(gao)壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如圖(tu)例），內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即(ji)與(yu)液壓(ya)(ya)油觸碰，故規(gui)定在(zai)(zai)長期性(xing)(xing)運行狀態(tai)下不可(ke)受液體浸蝕(shi)，能(neng)(neng)補漏(lou)。在(zai)(zai)提高(gao)層(ceng)(ceng)(ceng)功(gong)效(xiao)下會(hui)(hui)承擔(dan)一定工作壓(ya)(ya)力。因而，宜選(xuan)用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)(jiao)(jiao)粒外，危(wei)(wei)害性(xing)(xing)能(neng)(neng)的關(guan)鍵要(yao)(yao)素也有內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的強度(du)(du)、薄厚(hou)(hou)和(he)永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)量。強度(du)(du)和(he)永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)量對密封性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)(wei)害非常大。一般強度(du)(du)高(gao)、縮小后的永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)量小，密封性(xing)(xing)性(xing)(xing)能(neng)(neng)則越好(hao)。一般是在(zai)(zai)７０～８５邵(shao)氏(shi)硬度(du)(du)，縮小永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)５０％時。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄厚(hou)(hou)建議是為(wei)１．５～２．５ｍｍ，太厚(hou)(hou)會(hui)(hui)在(zai)(zai)壓(ya)(ya)扣(kou)時提升其流(liu)動率(lv)，導致不必要(yao)(yao)的膠(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯套與(yu)橡膠(jiao)(jiao)(jiao)(jiao)軟管的觸碰內(nei)孔(kong)內(nei)沉積，減(jian)少商品流(liu)通橫截面(mian)；過薄會(hui)(hui)在(zai)(zai)壓(ya)(ya)扣(kou)時被壓(ya)(ya)裂。另外內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚(hou)(hou)勻(yun)稱性(xing)(xing)也很重要(yao)(yao)。假如薄厚(hou)(hou)不勻(yun)，縮小后會(hui)(hui)導致一面(mian)裂斷(duan)、一面(mian)堆(dui)膠(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的浮銹也是危(wei)(wei)害性(xing)(xing)能(neng)(neng)品質的關(guan)鍵要(yao)(yao)素。
２）高(gao)壓(ya)(ya)膠(jiao)(jiao)管關鍵借助(zhu)提(ti)高(gao)層(ceng)(ceng)來承受力(li)(li)(li)。手工(gong)編織橡(xiang)膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)粘(zhan)緊，因為(wei)同一(yi)手工(gong)編織層(ceng)(ceng)內(nei)不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)中(zhong)(zhong)間(jian)(jian)的(de)(de)(de)互相觸(chu)碰，在(zai)承擔氣體(ti)壓(ya)(ya)力(li)(li)(li)的(de)(de)(de)時(shi)候會因分別伸縮式不(bu)(bu)一(yi)而導(dao)致(zhi)不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)彼此(ci)之間(jian)(jian)的(de)(de)(de)摩(mo)擦而危(wei)害其(qi)使(shi)用性能(neng)。而螺旋(xuan)波紋(wen)管是由盤繞方位不(bu)(bu)一(yi)樣的(de)(de)(de)雙層(ceng)(ceng)產(chan)生一(yi)個工(gong)作中(zhong)(zhong)層(ceng)(ceng)，在(zai)雙層(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)有正中(zhong)(zhong)間(jian)(jian)膠(jiao)(jiao)，因而同一(yi)工(gong)作中(zhong)(zhong)層(ceng)(ceng)的(de)(de)(de)雙層(ceng)(ceng)不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)中(zhong)(zhong)間(jian)(jian)沒有交(jiao)接點。因此(ci) 不(bu)(bu)容(rong)易在(zai)承擔氣體(ti)壓(ya)(ya)力(li)(li)(li)時(shi)同于不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)間(jian)(jian)的(de)(de)(de)交(jiao)叉式彎(wan)折而產(chan)生應力(li)(li)(li)或磨擦磨壞。故使(shi)用性能(neng)好，能(neng)承擔髙壓(ya)(ya)。
３）高(gao)壓膠(jiao)管(guan)(guan)的外膠(jiao)層粘在(zai)提高(gao)層上起維護功效，一(yi)般選用(yong)氯(lv)丁(ding)膠(jiao)。應留意避免 其脆(cui)化開裂而危害全部橡膠(jiao)軟管(guan)(guan)的使用(yong)壽(shou)命。
