１、橡膠軟管總成
1）高壓膠(jiao)(jiao)(jiao)(jiao)(jiao)管由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)、提(ti)高層(ceng)和外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)構(gou)成(cheng)（如圖例(li)），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)立即(ji)與液(ye)壓油觸碰，故規(gui)定在(zai)(zai)長期性(xing)(xing)(xing)(xing)運(yun)行狀(zhuang)態(tai)下(xia)(xia)不可(ke)受液(ye)體浸蝕，能(neng)補漏(lou)。在(zai)(zai)提(ti)高層(ceng)功效下(xia)(xia)會(hui)(hui)承擔一定工作壓力。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)(wai)，危害性(xing)(xing)(xing)(xing)能(neng)的關(guan)鍵要素也有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)的強度(du)、薄(bo)厚(hou)(hou)和永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)量。強度(du)和永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)量對(dui)密封(feng)(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)危害非常大。一般強度(du)高、縮小(xiao)后(hou)的永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)量小(xiao)，密封(feng)(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)則越好。一般是(shi)在(zai)(zai)７０～８５邵氏(shi)硬度(du)，縮小(xiao)永久(jiu)性(xing)(xing)(xing)(xing)形變(bian)５０％時(shi)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)薄(bo)厚(hou)(hou)建議是(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)(hou)會(hui)(hui)在(zai)(zai)壓扣(kou)(kou)時(shi)提(ti)升其流(liu)(liu)動(dong)率，導致(zhi)不必要的膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)(zai)接頭芯(xin)套與橡膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的觸碰內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積(ji)，減少商(shang)品流(liu)(liu)通橫截(jie)面；過薄(bo)會(hui)(hui)在(zai)(zai)壓扣(kou)(kou)時(shi)被(bei)壓裂(lie)。另(ling)外(wai)(wai)內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚(hou)(hou)勻稱性(xing)(xing)(xing)(xing)也很(hen)重要。假如薄(bo)厚(hou)(hou)不勻，縮小(xiao)后(hou)會(hui)(hui)導致(zhi)一面裂(lie)斷、一面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)表(biao)層(ceng)出現(xian)的浮(fu)銹也是(shi)危害性(xing)(xing)(xing)(xing)能(neng)品質的關(guan)鍵要素。
２）高壓膠(jiao)管(guan)關鍵借(jie)助(zhu)提高層(ceng)(ceng)來承受(shou)力。手工編(bian)織橡膠(jiao)軟(ruan)管(guan)是(shi)靠膠(jiao)漿與內外黏膠(jiao)粘緊，因(yin)(yin)為同一(yi)(yi)手工編(bian)織層(ceng)(ceng)內不(bu)(bu)銹(xiu)(xiu)鋼絲(si)中(zhong)間的(de)互相觸碰，在(zai)承擔氣(qi)體(ti)壓力的(de)時候(hou)會因(yin)(yin)分別(bie)伸縮式不(bu)(bu)一(yi)(yi)而(er)導致(zhi)不(bu)(bu)銹(xiu)(xiu)鋼絲(si)彼此(ci)(ci)之間的(de)摩擦而(er)危害其使用性(xing)能(neng)。而(er)螺旋波紋管(guan)是(shi)由盤繞方(fang)位不(bu)(bu)一(yi)(yi)樣的(de)雙(shuang)層(ceng)(ceng)產生(sheng)一(yi)(yi)個工作中(zhong)層(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)中(zhong)間有正中(zhong)間膠(jiao)，因(yin)(yin)而(er)同一(yi)(yi)工作中(zhong)層(ceng)(ceng)的(de)雙(shuang)層(ceng)(ceng)不(bu)(bu)銹(xiu)(xiu)鋼絲(si)中(zhong)間沒有交(jiao)接點。因(yin)(yin)此(ci)(ci) 不(bu)(bu)容(rong)易在(zai)承擔氣(qi)體(ti)壓力時同于不(bu)(bu)銹(xiu)(xiu)鋼絲(si)間的(de)交(jiao)叉(cha)式彎折而(er)產生(sheng)應力或磨擦磨壞。故(gu)使用性(xing)能(neng)好，能(neng)承擔髙(gao)壓。
３）高壓膠(jiao)(jiao)(jiao)管(guan)(guan)的外膠(jiao)(jiao)(jiao)層(ceng)粘在提高層(ceng)上起維護功(gong)效，一般選用(yong)氯丁膠(jiao)(jiao)(jiao)。應留意避(bi)免 其脆(cui)化開裂(lie)而危害全部(bu)橡膠(jiao)(jiao)(jiao)軟管(guan)(guan)的使用(yong)壽命。
