１、橡膠軟管總成
1）高(gao)(gao)壓(ya)(ya)(ya)膠(jiao)(jiao)(jiao)管(guan)由內(nei)膠(jiao)(jiao)(jiao)層、提(ti)高(gao)(gao)層和外(wai)(wai)膠(jiao)(jiao)(jiao)層構成（如(ru)圖(tu)例），內(nei)膠(jiao)(jiao)(jiao)層立即與液壓(ya)(ya)(ya)油(you)觸碰，故規(gui)定(ding)在(zai)長期(qi)性(xing)(xing)(xing)運行狀態(tai)下不(bu)可受液體浸(jin)蝕，能(neng)補漏。在(zai)提(ti)高(gao)(gao)層功效下會承擔(dan)一(yi)(yi)定(ding)工作壓(ya)(ya)(ya)力(li)。因(yin)而，宜選(xuan)用丁(ding)腈(jing)橡膠(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)粒外(wai)(wai)，危(wei)(wei)害性(xing)(xing)(xing)能(neng)的(de)(de)關鍵要素(su)也(ye)有內(nei)膠(jiao)(jiao)(jiao)層的(de)(de)強(qiang)度(du)(du)、薄厚(hou)和永(yong)久性(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)。強(qiang)度(du)(du)和永(yong)久性(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)對(dui)密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)危(wei)(wei)害非常大。一(yi)(yi)般強(qiang)度(du)(du)高(gao)(gao)、縮小后(hou)的(de)(de)永(yong)久性(xing)(xing)(xing)形(xing)變(bian)量(liang)(liang)小，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能(neng)則(ze)越好(hao)。一(yi)(yi)般是在(zai)７０～８５邵氏硬(ying)度(du)(du)，縮小永(yong)久性(xing)(xing)(xing)形(xing)變(bian)５０％時。內(nei)膠(jiao)(jiao)(jiao)層薄厚(hou)建(jian)議(yi)是為１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)壓(ya)(ya)(ya)扣(kou)(kou)時提(ti)升(sheng)其(qi)流動率，導(dao)致不(bu)必要的(de)(de)膠(jiao)(jiao)(jiao)在(zai)接(jie)頭芯套與橡膠(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸碰內(nei)孔內(nei)沉(chen)積(ji)，減(jian)少商品(pin)流通橫截面；過薄會在(zai)壓(ya)(ya)(ya)扣(kou)(kou)時被壓(ya)(ya)(ya)裂。另外(wai)(wai)內(nei)膠(jiao)(jiao)(jiao)層壁(bi)厚(hou)勻稱(cheng)性(xing)(xing)(xing)也(ye)很重要。假如(ru)薄厚(hou)不(bu)勻，縮小后(hou)會導(dao)致一(yi)(yi)面裂斷、一(yi)(yi)面堆膠(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)層表層出現的(de)(de)浮銹也(ye)是危(wei)(wei)害性(xing)(xing)(xing)能(neng)品(pin)質的(de)(de)關鍵要素(su)。
２）高壓(ya)膠(jiao)(jiao)管(guan)(guan)關鍵借助提(ti)高層(ceng)來承(cheng)受力(li)。手工(gong)(gong)編織橡膠(jiao)(jiao)軟管(guan)(guan)是靠膠(jiao)(jiao)漿與(yu)內外黏(nian)膠(jiao)(jiao)粘緊，因(yin)為同(tong)(tong)一(yi)手工(gong)(gong)編織層(ceng)內不(bu)銹(xiu)(xiu)鋼絲中(zhong)(zhong)(zhong)間的(de)互相觸碰，在(zai)承(cheng)擔氣(qi)體(ti)壓(ya)力(li)的(de)時候會因(yin)分別(bie)伸縮式不(bu)一(yi)而(er)導(dao)致不(bu)銹(xiu)(xiu)鋼絲彼此之(zhi)間的(de)摩擦而(er)危害其使用性能。而(er)螺旋波紋管(guan)(guan)是由(you)盤繞方位不(bu)一(yi)樣的(de)雙層(ceng)產生一(yi)個工(gong)(gong)作中(zhong)(zhong)(zhong)層(ceng)，在(zai)雙層(ceng)中(zhong)(zhong)(zhong)間有(you)正中(zhong)(zhong)(zhong)間膠(jiao)(jiao)，因(yin)而(er)同(tong)(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)(zhong)層(ceng)的(de)雙層(ceng)不(bu)銹(xiu)(xiu)鋼絲中(zhong)(zhong)(zhong)間沒(mei)有(you)交接點。因(yin)此 不(bu)容易在(zai)承(cheng)擔氣(qi)體(ti)壓(ya)力(li)時同(tong)(tong)于(yu)不(bu)銹(xiu)(xiu)鋼絲間的(de)交叉式彎折而(er)產生應力(li)或磨擦磨壞。故使用性能好，能承(cheng)擔髙壓(ya)。
３）高(gao)(gao)壓膠管的外膠層(ceng)粘在提高(gao)(gao)層(ceng)上起維護功效，一般選用氯丁膠。應留(liu)意避(bi)免(mian) 其脆化(hua)開裂而危害全(quan)部橡膠軟管的使用壽命(ming)。
