１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)、提高(gao)層(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)構成（如圖例），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)立即與(yu)液壓(ya)油觸碰(peng)，故規定在(zai)長期性(xing)(xing)(xing)(xing)(xing)(xing)運行(xing)狀態下不可受液體(ti)浸蝕，能(neng)(neng)補(bu)漏(lou)。在(zai)提高(gao)層(ceng)功(gong)效下會(hui)(hui)承擔一(yi)(yi)定工作(zuo)壓(ya)力(li)。因而，宜選用丁腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)的(de)關(guan)鍵要(yao)素也有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)的(de)強(qiang)度(du)(du)(du)、薄厚和(he)永久(jiu)性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量。強(qiang)度(du)(du)(du)和(he)永久(jiu)性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量對密封性(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)危(wei)害(hai)非常大。一(yi)(yi)般強(qiang)度(du)(du)(du)高(gao)、縮小(xiao)后的(de)永久(jiu)性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)量小(xiao)，密封性(xing)(xing)(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)則越好。一(yi)(yi)般是(shi)在(zai)７０～８５邵(shao)氏硬度(du)(du)(du)，縮小(xiao)永久(jiu)性(xing)(xing)(xing)(xing)(xing)(xing)形(xing)變(bian)５０％時。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)薄厚建(jian)議是(shi)為１．５～２．５ｍｍ，太厚會(hui)(hui)在(zai)壓(ya)扣時提升其流(liu)動率，導致不必要(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接(jie)頭芯套與(yu)橡膠(jiao)(jiao)(jiao)(jiao)軟(ruan)管(guan)(guan)的(de)觸碰(peng)內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商(shang)品流(liu)通橫(heng)截面(mian)(mian)；過薄會(hui)(hui)在(zai)壓(ya)扣時被壓(ya)裂。另外內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚勻稱性(xing)(xing)(xing)(xing)(xing)(xing)也很重要(yao)。假如薄厚不勻，縮小(xiao)后會(hui)(hui)導致一(yi)(yi)面(mian)(mian)裂斷、一(yi)(yi)面(mian)(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)表層(ceng)出現(xian)的(de)浮銹(xiu)也是(shi)危(wei)害(hai)性(xing)(xing)(xing)(xing)(xing)(xing)能(neng)(neng)品質的(de)關(guan)鍵要(yao)素。
２）高壓(ya)(ya)膠(jiao)管(guan)(guan)關(guan)鍵借(jie)助提高層(ceng)來承受力(li)。手工編織(zhi)橡膠(jiao)軟管(guan)(guan)是(shi)靠膠(jiao)漿與內外黏膠(jiao)粘緊，因(yin)為同一(yi)(yi)手工編織(zhi)層(ceng)內不(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)間(jian)的(de)(de)互(hu)相觸碰(peng)，在承擔氣體壓(ya)(ya)力(li)的(de)(de)時候(hou)會(hui)因(yin)分別伸(shen)縮式(shi)(shi)不(bu)(bu)一(yi)(yi)而(er)(er)導致不(bu)(bu)銹(xiu)鋼(gang)絲彼此之間(jian)的(de)(de)摩(mo)擦而(er)(er)危害其使用性(xing)能。而(er)(er)螺旋波紋管(guan)(guan)是(shi)由盤繞方位不(bu)(bu)一(yi)(yi)樣的(de)(de)雙層(ceng)產生(sheng)(sheng)一(yi)(yi)個(ge)工作中(zhong)(zhong)層(ceng)，在雙層(ceng)中(zhong)(zhong)間(jian)有(you)正中(zhong)(zhong)間(jian)膠(jiao)，因(yin)而(er)(er)同一(yi)(yi)工作中(zhong)(zhong)層(ceng)的(de)(de)雙層(ceng)不(bu)(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)間(jian)沒有(you)交(jiao)接點。因(yin)此 不(bu)(bu)容易在承擔氣體壓(ya)(ya)力(li)時同于(yu)不(bu)(bu)銹(xiu)鋼(gang)絲間(jian)的(de)(de)交(jiao)叉式(shi)(shi)彎折(zhe)而(er)(er)產生(sheng)(sheng)應(ying)力(li)或磨擦磨壞。故使用性(xing)能好，能承擔髙壓(ya)(ya)。
３）高(gao)壓膠管的外膠層(ceng)粘在提高(gao)層(ceng)上起(qi)維護功效，一(yi)般選用氯丁膠。應(ying)留意避(bi)免(mian) 其脆化開裂而危害全部橡(xiang)膠軟管的使用壽(shou)命(ming)。
