１、橡膠軟管總成
1）高(gao)壓膠(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)、提高(gao)層(ceng)和(he)外(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)構成(cheng)（如圖(tu)例(li)），內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)立即與(yu)液壓油(you)觸(chu)碰，故(gu)規定在(zai)長期性(xing)(xing)運行狀態下不(bu)可受(shou)液體浸蝕，能(neng)補漏。在(zai)提高(gao)層(ceng)功效下會承擔一定工作壓力。因(yin)而(er)，宜選用丁腈(jing)橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒(li)外(wai)，危害(hai)性(xing)(xing)能(neng)的(de)(de)關(guan)鍵要素也有內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)的(de)(de)強(qiang)度、薄厚(hou)和(he)永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變量。強(qiang)度和(he)永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變量對密封(feng)性(xing)(xing)性(xing)(xing)能(neng)危害(hai)非常大。一般強(qiang)度高(gao)、縮(suo)小后的(de)(de)永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變量小，密封(feng)性(xing)(xing)性(xing)(xing)能(neng)則(ze)越好(hao)。一般是(shi)在(zai)７０～８５邵氏硬(ying)度，縮(suo)小永(yong)(yong)久(jiu)性(xing)(xing)形(xing)(xing)變５０％時(shi)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)薄厚(hou)建(jian)議是(shi)為(wei)１．５～２．５ｍｍ，太厚(hou)會在(zai)壓扣時(shi)提升其流動率，導致(zhi)不(bu)必要的(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套(tao)與(yu)橡膠(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)觸(chu)碰內(nei)孔內(nei)沉積，減少商(shang)品(pin)流通橫截面；過薄會在(zai)壓扣時(shi)被(bei)壓裂。另外(wai)內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚(hou)勻(yun)稱性(xing)(xing)也很重要。假如薄厚(hou)不(bu)勻(yun)，縮(suo)小后會導致(zhi)一面裂斷、一面堆(dui)膠(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)表(biao)層(ceng)出現(xian)的(de)(de)浮銹(xiu)也是(shi)危害(hai)性(xing)(xing)能(neng)品(pin)質的(de)(de)關(guan)鍵要素。
２）高(gao)壓膠(jiao)(jiao)管關鍵借助提高(gao)層(ceng)(ceng)來承(cheng)(cheng)(cheng)受(shou)力(li)。手工編織橡膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與(yu)內外(wai)黏膠(jiao)(jiao)粘緊，因為同(tong)一手工編織層(ceng)(ceng)內不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)絲中(zhong)(zhong)間(jian)(jian)的(de)(de)(de)互相觸(chu)碰(peng)，在承(cheng)(cheng)(cheng)擔氣體壓力(li)的(de)(de)(de)時候(hou)會因分別伸縮式不(bu)(bu)(bu)(bu)一而(er)導致不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)絲彼此(ci)之間(jian)(jian)的(de)(de)(de)摩(mo)擦而(er)危害(hai)其使(shi)用性能。而(er)螺(luo)旋波紋管是由盤繞方(fang)位不(bu)(bu)(bu)(bu)一樣的(de)(de)(de)雙(shuang)層(ceng)(ceng)產生(sheng)一個工作中(zhong)(zhong)層(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)中(zhong)(zhong)間(jian)(jian)有正中(zhong)(zhong)間(jian)(jian)膠(jiao)(jiao)，因而(er)同(tong)一工作中(zhong)(zhong)層(ceng)(ceng)的(de)(de)(de)雙(shuang)層(ceng)(ceng)不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)絲中(zhong)(zhong)間(jian)(jian)沒有交(jiao)接(jie)點。因此(ci) 不(bu)(bu)(bu)(bu)容(rong)易(yi)在承(cheng)(cheng)(cheng)擔氣體壓力(li)時同(tong)于不(bu)(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)絲間(jian)(jian)的(de)(de)(de)交(jiao)叉式彎折而(er)產生(sheng)應(ying)力(li)或(huo)磨擦磨壞。故使(shi)用性能好，能承(cheng)(cheng)(cheng)擔髙壓。
３）高壓膠(jiao)管的(de)外膠(jiao)層粘在提高層上起維護功效，一般選用(yong)氯丁膠(jiao)。應留意避(bi)免(mian) 其(qi)脆化開裂而危害全(quan)部橡膠(jiao)軟管的(de)使用(yong)壽命。
