１、橡膠軟管總成
1）高壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)、提高層(ceng)(ceng)(ceng)(ceng)和外膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)構成（如(ru)圖例），內膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)立即與液壓(ya)(ya)油(you)觸(chu)碰，故規定在(zai)長期性(xing)(xing)(xing)(xing)運行狀態下(xia)不可受液體浸蝕(shi)，能(neng)補漏。在(zai)提高層(ceng)(ceng)(ceng)(ceng)功效下(xia)會承擔一定工作壓(ya)(ya)力。因而，宜選用(yong)丁腈橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒外，危(wei)害性(xing)(xing)(xing)(xing)能(neng)的(de)關鍵(jian)要(yao)素也有內膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)的(de)強度(du)(du)、薄(bo)厚(hou)和永久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)(bian)(bian)量(liang)。強度(du)(du)和永久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)(bian)(bian)量(liang)對(dui)密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)危(wei)害非常大。一般強度(du)(du)高、縮(suo)小后的(de)永久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)(bian)(bian)量(liang)小，密封性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)則越好。一般是(shi)在(zai)７０～８５邵氏硬度(du)(du)，縮(suo)小永久(jiu)(jiu)性(xing)(xing)(xing)(xing)形(xing)(xing)(xing)變(bian)(bian)(bian)５０％時(shi)。內膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)薄(bo)厚(hou)建議是(shi)為１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)壓(ya)(ya)扣(kou)時(shi)提升其流(liu)動率(lv)，導(dao)致不必要(yao)的(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套與橡(xiang)(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)觸(chu)碰內孔內沉積，減少商(shang)品流(liu)通(tong)橫(heng)截面；過(guo)薄(bo)會在(zai)壓(ya)(ya)扣(kou)時(shi)被壓(ya)(ya)裂。另外內膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)壁厚(hou)勻(yun)稱性(xing)(xing)(xing)(xing)也很重(zhong)要(yao)。假如(ru)薄(bo)厚(hou)不勻(yun)，縮(suo)小后會導(dao)致一面裂斷(duan)、一面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)出現的(de)浮銹也是(shi)危(wei)害性(xing)(xing)(xing)(xing)能(neng)品質的(de)關鍵(jian)要(yao)素。
２）高(gao)壓膠(jiao)(jiao)管關鍵借(jie)助提高(gao)層來承(cheng)受力。手工(gong)編織橡膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與內外黏膠(jiao)(jiao)粘緊(jin)，因為同(tong)一(yi)(yi)手工(gong)編織層內不(bu)銹(xiu)鋼(gang)(gang)絲中(zhong)間(jian)(jian)的(de)互(hu)相觸(chu)碰(peng)，在承(cheng)擔氣體壓力的(de)時候會因分別伸縮式(shi)不(bu)一(yi)(yi)而導(dao)致不(bu)銹(xiu)鋼(gang)(gang)絲彼此之間(jian)(jian)的(de)摩(mo)擦而危害其(qi)使(shi)用(yong)性(xing)能(neng)(neng)。而螺旋波紋(wen)管是由盤繞方位不(bu)一(yi)(yi)樣(yang)的(de)雙(shuang)層產(chan)生一(yi)(yi)個工(gong)作中(zhong)層，在雙(shuang)層中(zhong)間(jian)(jian)有(you)正中(zhong)間(jian)(jian)膠(jiao)(jiao)，因而同(tong)一(yi)(yi)工(gong)作中(zhong)層的(de)雙(shuang)層不(bu)銹(xiu)鋼(gang)(gang)絲中(zhong)間(jian)(jian)沒(mei)有(you)交接(jie)點。因此 不(bu)容易在承(cheng)擔氣體壓力時同(tong)于不(bu)銹(xiu)鋼(gang)(gang)絲間(jian)(jian)的(de)交叉式(shi)彎(wan)折而產(chan)生應力或磨擦磨壞。故使(shi)用(yong)性(xing)能(neng)(neng)好，能(neng)(neng)承(cheng)擔髙壓。
３）高壓膠管(guan)的外膠層(ceng)粘在提(ti)高層(ceng)上起維護功效，一般選用氯丁膠。應留意避(bi)免 其脆化開裂而(er)危害全部橡膠軟管(guan)的使用壽命。
