１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提高(gao)層(ceng)(ceng)(ceng)(ceng)和(he)外(wai)(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構(gou)成（如圖例），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即(ji)與(yu)液壓(ya)油觸碰(peng)(peng)，故規定在(zai)長(chang)期性(xing)(xing)(xing)(xing)運行狀態(tai)下不可受(shou)液體浸蝕，能補漏。在(zai)提高(gao)層(ceng)(ceng)(ceng)(ceng)功效下會(hui)承(cheng)擔一(yi)(yi)定工作壓(ya)力。因而，宜選用丁腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外(wai)(wai)，危(wei)害(hai)性(xing)(xing)(xing)(xing)能的(de)(de)關鍵要(yao)素也有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)(de)強(qiang)度(du)、薄(bo)厚和(he)永久(jiu)性(xing)(xing)(xing)(xing)形變量(liang)。強(qiang)度(du)和(he)永久(jiu)性(xing)(xing)(xing)(xing)形變量(liang)對密封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能危(wei)害(hai)非(fei)常大。一(yi)(yi)般(ban)強(qiang)度(du)高(gao)、縮小后(hou)的(de)(de)永久(jiu)性(xing)(xing)(xing)(xing)形變量(liang)小，密封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能則越(yue)好。一(yi)(yi)般(ban)是(shi)(shi)在(zai)７０～８５邵氏硬度(du)，縮小永久(jiu)性(xing)(xing)(xing)(xing)形變５０％時(shi)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄(bo)厚建議是(shi)(shi)為１．５～２．５ｍｍ，太厚會(hui)在(zai)壓(ya)扣時(shi)提升其流(liu)動率(lv)，導致不必(bi)要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套與(yu)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟(ruan)管的(de)(de)觸碰(peng)(peng)內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商(shang)品流(liu)通橫截面；過薄(bo)會(hui)在(zai)壓(ya)扣時(shi)被壓(ya)裂。另外(wai)(wai)內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁(bi)厚勻稱性(xing)(xing)(xing)(xing)也很重要(yao)。假如薄(bo)厚不勻，縮小后(hou)會(hui)導致一(yi)(yi)面裂斷(duan)、一(yi)(yi)面堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出現(xian)的(de)(de)浮銹也是(shi)(shi)危(wei)害(hai)性(xing)(xing)(xing)(xing)能品質的(de)(de)關鍵要(yao)素。
２）高(gao)壓膠(jiao)管關鍵借助提高(gao)層(ceng)來承(cheng)受力。手工(gong)(gong)編(bian)織(zhi)橡(xiang)膠(jiao)軟(ruan)管是(shi)靠膠(jiao)漿與內外黏膠(jiao)粘緊，因為同(tong)一手工(gong)(gong)編(bian)織(zhi)層(ceng)內不(bu)銹(xiu)鋼(gang)(gang)絲中間的(de)互(hu)相觸碰，在(zai)(zai)承(cheng)擔(dan)氣(qi)體(ti)壓力的(de)時候(hou)會(hui)因分別伸縮式(shi)(shi)不(bu)一而(er)導致(zhi)不(bu)銹(xiu)鋼(gang)(gang)絲彼(bi)此(ci)之間的(de)摩(mo)擦(ca)而(er)危害其(qi)使用性(xing)能。而(er)螺旋波紋管是(shi)由盤繞方位不(bu)一樣的(de)雙層(ceng)產生(sheng)(sheng)一個工(gong)(gong)作中層(ceng)，在(zai)(zai)雙層(ceng)中間有正中間膠(jiao)，因而(er)同(tong)一工(gong)(gong)作中層(ceng)的(de)雙層(ceng)不(bu)銹(xiu)鋼(gang)(gang)絲中間沒有交接點。因此(ci) 不(bu)容(rong)易在(zai)(zai)承(cheng)擔(dan)氣(qi)體(ti)壓力時同(tong)于不(bu)銹(xiu)鋼(gang)(gang)絲間的(de)交叉式(shi)(shi)彎折而(er)產生(sheng)(sheng)應力或磨擦(ca)磨壞。故使用性(xing)能好，能承(cheng)擔(dan)髙壓。
３）高(gao)壓膠管的(de)(de)外膠層粘(zhan)在提(ti)高(gao)層上起維護功效(xiao)，一(yi)般(ban)選用氯丁膠。應留意避免 其脆化開(kai)裂而危害全部(bu)橡膠軟(ruan)管的(de)(de)使用壽命。
