１、橡膠軟管總成
1）高壓膠(jiao)(jiao)(jiao)(jiao)(jiao)管(guan)由內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)、提(ti)(ti)高層(ceng)和(he)外膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)構成(cheng)（如圖例(li)），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)立即與液(ye)壓油觸(chu)碰，故規定(ding)(ding)在(zai)長期性(xing)(xing)(xing)(xing)運行狀態下不(bu)可受液(ye)體(ti)浸蝕(shi)，能(neng)(neng)(neng)補漏。在(zai)提(ti)(ti)高層(ceng)功效下會(hui)(hui)承(cheng)擔一(yi)定(ding)(ding)工作壓力。因(yin)而，宜選(xuan)用(yong)丁(ding)腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)(jiao)粒外，危(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)的(de)(de)關(guan)鍵要(yao)素也有(you)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)的(de)(de)強度(du)、薄厚(hou)(hou)(hou)和(he)永久性(xing)(xing)(xing)(xing)形(xing)變量(liang)。強度(du)和(he)永久性(xing)(xing)(xing)(xing)形(xing)變量(liang)對密(mi)封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)危(wei)害(hai)非常大(da)。一(yi)般(ban)(ban)強度(du)高、縮小(xiao)后的(de)(de)永久性(xing)(xing)(xing)(xing)形(xing)變量(liang)小(xiao)，密(mi)封(feng)性(xing)(xing)(xing)(xing)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)則越好。一(yi)般(ban)(ban)是(shi)在(zai)７０～８５邵氏(shi)硬度(du)，縮小(xiao)永久性(xing)(xing)(xing)(xing)形(xing)變５０％時(shi)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)薄厚(hou)(hou)(hou)建議是(shi)為１．５～２．５ｍｍ，太厚(hou)(hou)(hou)會(hui)(hui)在(zai)壓扣時(shi)提(ti)(ti)升其流動率(lv)，導(dao)致不(bu)必要(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)接(jie)頭(tou)芯套與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管(guan)的(de)(de)觸(chu)碰內(nei)(nei)孔內(nei)(nei)沉積，減少商品流通橫截面；過薄會(hui)(hui)在(zai)壓扣時(shi)被壓裂。另外內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚(hou)(hou)(hou)勻稱性(xing)(xing)(xing)(xing)也很重要(yao)。假如薄厚(hou)(hou)(hou)不(bu)勻，縮小(xiao)后會(hui)(hui)導(dao)致一(yi)面裂斷、一(yi)面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)表層(ceng)出現(xian)的(de)(de)浮銹也是(shi)危(wei)害(hai)性(xing)(xing)(xing)(xing)能(neng)(neng)(neng)品質的(de)(de)關(guan)鍵要(yao)素。
２）高壓膠管關鍵借助提高層來承受力(li)。手工(gong)編(bian)織(zhi)橡膠軟管是(shi)(shi)靠膠漿與(yu)內(nei)外黏膠粘緊，因為(wei)同一(yi)(yi)手工(gong)編(bian)織(zhi)層內(nei)不(bu)(bu)銹鋼(gang)(gang)絲中(zhong)間(jian)的(de)互(hu)相觸碰，在承擔(dan)(dan)氣體壓力(li)的(de)時候會因分別伸縮式不(bu)(bu)一(yi)(yi)而(er)(er)導(dao)致(zhi)不(bu)(bu)銹鋼(gang)(gang)絲彼此(ci)之(zhi)間(jian)的(de)摩擦而(er)(er)危害其(qi)使(shi)用性(xing)能(neng)。而(er)(er)螺旋波紋(wen)管是(shi)(shi)由盤(pan)繞方位不(bu)(bu)一(yi)(yi)樣的(de)雙層產生(sheng)一(yi)(yi)個工(gong)作中(zhong)層，在雙層中(zhong)間(jian)有正(zheng)中(zhong)間(jian)膠，因而(er)(er)同一(yi)(yi)工(gong)作中(zhong)層的(de)雙層不(bu)(bu)銹鋼(gang)(gang)絲中(zhong)間(jian)沒(mei)有交接點。因此(ci) 不(bu)(bu)容易在承擔(dan)(dan)氣體壓力(li)時同于(yu)不(bu)(bu)銹鋼(gang)(gang)絲間(jian)的(de)交叉式彎折(zhe)而(er)(er)產生(sheng)應(ying)力(li)或磨擦磨壞。故(gu)使(shi)用性(xing)能(neng)好，能(neng)承擔(dan)(dan)髙壓。
３）高(gao)(gao)壓膠管的外膠層粘(zhan)在提高(gao)(gao)層上起(qi)維護功效(xiao)，一般(ban)選(xuan)用氯丁(ding)膠。應留(liu)意避免 其脆化開裂而危害全(quan)部橡膠軟管的使用壽命。
