１、橡膠軟管總成
1）高(gao)壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由內膠(jiao)(jiao)(jiao)(jiao)層(ceng)、提高(gao)層(ceng)和(he)(he)外(wai)膠(jiao)(jiao)(jiao)(jiao)層(ceng)構成（如(ru)圖例），內膠(jiao)(jiao)(jiao)(jiao)層(ceng)立(li)即與液(ye)(ye)壓(ya)油觸(chu)碰，故規定(ding)在(zai)長期性(xing)(xing)(xing)運行狀態下(xia)不可受液(ye)(ye)體(ti)浸蝕(shi)，能補(bu)漏。在(zai)提高(gao)層(ceng)功效下(xia)會(hui)承擔一(yi)定(ding)工作壓(ya)力。因而(er)，宜選(xuan)用丁(ding)腈橡膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外(wai)，危害性(xing)(xing)(xing)能的關(guan)鍵要(yao)素(su)也有內膠(jiao)(jiao)(jiao)(jiao)層(ceng)的強度(du)、薄厚(hou)(hou)和(he)(he)永久(jiu)性(xing)(xing)(xing)形(xing)變量(liang)。強度(du)和(he)(he)永久(jiu)性(xing)(xing)(xing)形(xing)變量(liang)對密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能危害非常大。一(yi)般強度(du)高(gao)、縮(suo)小(xiao)(xiao)后的永久(jiu)性(xing)(xing)(xing)形(xing)變量(liang)小(xiao)(xiao)，密封(feng)性(xing)(xing)(xing)性(xing)(xing)(xing)能則越好。一(yi)般是(shi)在(zai)７０～８５邵(shao)氏硬度(du)，縮(suo)小(xiao)(xiao)永久(jiu)性(xing)(xing)(xing)形(xing)變５０％時。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)薄厚(hou)(hou)建(jian)議是(shi)為(wei)１．５～２．５ｍｍ，太厚(hou)(hou)會(hui)在(zai)壓(ya)扣時提升其流(liu)動率，導(dao)致不必要(yao)的膠(jiao)(jiao)(jiao)(jiao)在(zai)接(jie)頭(tou)芯套與橡膠(jiao)(jiao)(jiao)(jiao)軟管的觸(chu)碰內孔內沉積(ji)，減少商品(pin)流(liu)通橫截面(mian)；過薄會(hui)在(zai)壓(ya)扣時被壓(ya)裂。另外(wai)內膠(jiao)(jiao)(jiao)(jiao)層(ceng)壁厚(hou)(hou)勻(yun)(yun)稱性(xing)(xing)(xing)也很(hen)重要(yao)。假如(ru)薄厚(hou)(hou)不勻(yun)(yun)，縮(suo)小(xiao)(xiao)后會(hui)導(dao)致一(yi)面(mian)裂斷(duan)、一(yi)面(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內膠(jiao)(jiao)(jiao)(jiao)層(ceng)表層(ceng)出(chu)現的浮銹也是(shi)危害性(xing)(xing)(xing)能品(pin)質的關(guan)鍵要(yao)素(su)。
２）高壓(ya)膠(jiao)(jiao)管關鍵借(jie)助提高層(ceng)(ceng)來承受力(li)(li)。手工編織橡(xiang)膠(jiao)(jiao)軟管是靠膠(jiao)(jiao)漿與內(nei)外黏膠(jiao)(jiao)粘緊，因(yin)(yin)(yin)為同(tong)一手工編織層(ceng)(ceng)內(nei)不銹(xiu)鋼(gang)(gang)絲(si)(si)中(zhong)(zhong)(zhong)間(jian)(jian)的(de)互相觸碰，在承擔(dan)氣(qi)體(ti)(ti)壓(ya)力(li)(li)的(de)時候會(hui)因(yin)(yin)(yin)分別伸(shen)縮式不一而導致不銹(xiu)鋼(gang)(gang)絲(si)(si)彼此(ci)之間(jian)(jian)的(de)摩擦(ca)而危害其使(shi)用(yong)性(xing)能(neng)。而螺旋波(bo)紋管是由盤繞方位不一樣的(de)雙(shuang)層(ceng)(ceng)產(chan)生一個工作(zuo)中(zhong)(zhong)(zhong)層(ceng)(ceng)，在雙(shuang)層(ceng)(ceng)中(zhong)(zhong)(zhong)間(jian)(jian)有(you)正中(zhong)(zhong)(zhong)間(jian)(jian)膠(jiao)(jiao)，因(yin)(yin)(yin)而同(tong)一工作(zuo)中(zhong)(zhong)(zhong)層(ceng)(ceng)的(de)雙(shuang)層(ceng)(ceng)不銹(xiu)鋼(gang)(gang)絲(si)(si)中(zhong)(zhong)(zhong)間(jian)(jian)沒有(you)交接點。因(yin)(yin)(yin)此(ci) 不容易在承擔(dan)氣(qi)體(ti)(ti)壓(ya)力(li)(li)時同(tong)于不銹(xiu)鋼(gang)(gang)絲(si)(si)間(jian)(jian)的(de)交叉式彎(wan)折而產(chan)生應力(li)(li)或磨(mo)(mo)擦(ca)磨(mo)(mo)壞。故使(shi)用(yong)性(xing)能(neng)好(hao)，能(neng)承擔(dan)髙壓(ya)。
３）高(gao)壓膠管(guan)的外膠層粘在(zai)提高(gao)層上(shang)起維護功效，一般選用氯丁膠。應留意避免(mian) 其脆化開裂而危害全部(bu)橡膠軟管(guan)的使用壽(shou)命。
