１、橡膠軟管總成
1）高(gao)(gao)壓膠(jiao)(jiao)(jiao)(jiao)管由內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)、提高(gao)(gao)層(ceng)(ceng)和(he)(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)構(gou)成(cheng)（如圖例），內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)立即與液(ye)壓油觸(chu)碰，故(gu)規定(ding)在(zai)長期性(xing)(xing)(xing)運行狀態下不(bu)可受液(ye)體浸蝕，能補漏(lou)。在(zai)提高(gao)(gao)層(ceng)(ceng)功效(xiao)下會(hui)(hui)承擔一(yi)定(ding)工作壓力。因而，宜選用丁腈橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危(wei)(wei)害(hai)性(xing)(xing)(xing)能的(de)(de)(de)關鍵(jian)要素也(ye)有內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)的(de)(de)(de)強度(du)、薄(bo)厚(hou)和(he)(he)永(yong)(yong)久(jiu)性(xing)(xing)(xing)形變(bian)量。強度(du)和(he)(he)永(yong)(yong)久(jiu)性(xing)(xing)(xing)形變(bian)量對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能危(wei)(wei)害(hai)非常大(da)。一(yi)般(ban)強度(du)高(gao)(gao)、縮小(xiao)后(hou)的(de)(de)(de)永(yong)(yong)久(jiu)性(xing)(xing)(xing)形變(bian)量小(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能則(ze)越好。一(yi)般(ban)是(shi)在(zai)７０～８５邵氏硬度(du)，縮小(xiao)永(yong)(yong)久(jiu)性(xing)(xing)(xing)形變(bian)５０％時。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)薄(bo)厚(hou)建議是(shi)為(wei)１．５～２．５ｍｍ，太厚(hou)會(hui)(hui)在(zai)壓扣時提升其流(liu)動率，導(dao)致(zhi)不(bu)必要的(de)(de)(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭(tou)芯套(tao)與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)(de)觸(chu)碰內(nei)孔(kong)內(nei)沉積(ji)，減少商(shang)品(pin)流(liu)通橫截(jie)面(mian)(mian)；過薄(bo)會(hui)(hui)在(zai)壓扣時被壓裂(lie)。另外內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)壁厚(hou)勻稱性(xing)(xing)(xing)也(ye)很重要。假如薄(bo)厚(hou)不(bu)勻，縮小(xiao)后(hou)會(hui)(hui)導(dao)致(zhi)一(yi)面(mian)(mian)裂(lie)斷、一(yi)面(mian)(mian)堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現(xian)的(de)(de)(de)浮銹也(ye)是(shi)危(wei)(wei)害(hai)性(xing)(xing)(xing)能品(pin)質的(de)(de)(de)關鍵(jian)要素。
２）高壓(ya)膠管(guan)(guan)關鍵借助(zhu)提(ti)高層來承(cheng)(cheng)受力。手工編(bian)織橡膠軟管(guan)(guan)是(shi)靠膠漿與內外黏膠粘緊，因(yin)為(wei)同(tong)一手工編(bian)織層內不(bu)銹鋼(gang)絲(si)(si)(si)中(zhong)間(jian)(jian)(jian)的(de)(de)互(hu)相觸碰(peng)，在承(cheng)(cheng)擔氣體(ti)壓(ya)力的(de)(de)時候會因(yin)分別(bie)伸縮式不(bu)一而導(dao)致不(bu)銹鋼(gang)絲(si)(si)(si)彼此之間(jian)(jian)(jian)的(de)(de)摩擦(ca)而危害其使(shi)用性能。而螺(luo)旋波紋管(guan)(guan)是(shi)由盤繞(rao)方位不(bu)一樣的(de)(de)雙(shuang)層產(chan)生(sheng)一個工作中(zhong)層，在雙(shuang)層中(zhong)間(jian)(jian)(jian)有正中(zhong)間(jian)(jian)(jian)膠，因(yin)而同(tong)一工作中(zhong)層的(de)(de)雙(shuang)層不(bu)銹鋼(gang)絲(si)(si)(si)中(zhong)間(jian)(jian)(jian)沒有交(jiao)接點。因(yin)此 不(bu)容易在承(cheng)(cheng)擔氣體(ti)壓(ya)力時同(tong)于不(bu)銹鋼(gang)絲(si)(si)(si)間(jian)(jian)(jian)的(de)(de)交(jiao)叉式彎折而產(chan)生(sheng)應(ying)力或磨擦(ca)磨壞(huai)。故使(shi)用性能好，能承(cheng)(cheng)擔髙壓(ya)。
３）高壓膠(jiao)(jiao)(jiao)管的外膠(jiao)(jiao)(jiao)層粘在提高層上(shang)起維護功效，一般選用氯(lv)丁膠(jiao)(jiao)(jiao)。應留意(yi)避免 其(qi)脆化開(kai)裂而危害全部(bu)橡膠(jiao)(jiao)(jiao)軟管的使用壽(shou)命。
