１、橡膠軟管總成
1）高壓(ya)(ya)(ya)膠(jiao)管由(you)內(nei)膠(jiao)層(ceng)(ceng)、提(ti)高層(ceng)(ceng)和外(wai)膠(jiao)層(ceng)(ceng)構成(cheng)（如圖例），內(nei)膠(jiao)層(ceng)(ceng)立(li)即與液(ye)壓(ya)(ya)(ya)油觸碰(peng)，故規定(ding)在長期性(xing)(xing)(xing)運行狀(zhuang)態(tai)下不可受液(ye)體(ti)浸(jin)蝕，能補漏。在提(ti)高層(ceng)(ceng)功效下會承(cheng)擔一定(ding)工作壓(ya)(ya)(ya)力。因(yin)而(er)，宜選用丁(ding)腈(jing)橡膠(jiao)，除塑膠(jiao)粒外(wai)，危(wei)害性(xing)(xing)(xing)能的(de)(de)(de)(de)關鍵(jian)要(yao)(yao)素也(ye)(ye)有內(nei)膠(jiao)層(ceng)(ceng)的(de)(de)(de)(de)強度(du)(du)、薄(bo)(bo)(bo)厚(hou)和永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變量(liang)(liang)。強度(du)(du)和永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變量(liang)(liang)對密封性(xing)(xing)(xing)性(xing)(xing)(xing)能危(wei)害非(fei)常大。一般(ban)強度(du)(du)高、縮小(xiao)后的(de)(de)(de)(de)永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變量(liang)(liang)小(xiao)，密封性(xing)(xing)(xing)性(xing)(xing)(xing)能則越好。一般(ban)是(shi)在７０～８５邵氏硬度(du)(du)，縮小(xiao)永(yong)(yong)久(jiu)(jiu)性(xing)(xing)(xing)形(xing)(xing)變５０％時(shi)(shi)(shi)。內(nei)膠(jiao)層(ceng)(ceng)薄(bo)(bo)(bo)厚(hou)建議是(shi)為１．５～２．５ｍｍ，太厚(hou)會在壓(ya)(ya)(ya)扣(kou)時(shi)(shi)(shi)提(ti)升其流動率，導(dao)致不必要(yao)(yao)的(de)(de)(de)(de)膠(jiao)在接頭芯套與橡膠(jiao)軟管的(de)(de)(de)(de)觸碰(peng)內(nei)孔內(nei)沉積(ji)，減(jian)少(shao)商品流通橫截面；過薄(bo)(bo)(bo)會在壓(ya)(ya)(ya)扣(kou)時(shi)(shi)(shi)被壓(ya)(ya)(ya)裂。另外(wai)內(nei)膠(jiao)層(ceng)(ceng)壁厚(hou)勻(yun)稱性(xing)(xing)(xing)也(ye)(ye)很重要(yao)(yao)。假如薄(bo)(bo)(bo)厚(hou)不勻(yun)，縮小(xiao)后會導(dao)致一面裂斷、一面堆膠(jiao)。內(nei)膠(jiao)層(ceng)(ceng)表層(ceng)(ceng)出現(xian)的(de)(de)(de)(de)浮銹(xiu)也(ye)(ye)是(shi)危(wei)害性(xing)(xing)(xing)能品質的(de)(de)(de)(de)關鍵(jian)要(yao)(yao)素。
２）高(gao)壓膠(jiao)(jiao)管關鍵借助提高(gao)層(ceng)來承(cheng)受力(li)。手工(gong)編織橡(xiang)膠(jiao)(jiao)軟管是(shi)靠膠(jiao)(jiao)漿(jiang)與內外(wai)黏膠(jiao)(jiao)粘緊，因為(wei)同(tong)一(yi)(yi)手工(gong)編織層(ceng)內不銹鋼絲(si)(si)中間(jian)的(de)互相觸碰，在(zai)承(cheng)擔氣(qi)體(ti)(ti)壓力(li)的(de)時(shi)(shi)候會(hui)因分別伸(shen)縮式不一(yi)(yi)而(er)導致不銹鋼絲(si)(si)彼此之(zhi)間(jian)的(de)摩擦而(er)危害其使(shi)用性(xing)能(neng)。而(er)螺旋波(bo)紋管是(shi)由盤繞方位不一(yi)(yi)樣的(de)雙(shuang)層(ceng)產(chan)生一(yi)(yi)個工(gong)作中層(ceng)，在(zai)雙(shuang)層(ceng)中間(jian)有(you)正(zheng)中間(jian)膠(jiao)(jiao)，因而(er)同(tong)一(yi)(yi)工(gong)作中層(ceng)的(de)雙(shuang)層(ceng)不銹鋼絲(si)(si)中間(jian)沒有(you)交(jiao)接點。因此 不容易在(zai)承(cheng)擔氣(qi)體(ti)(ti)壓力(li)時(shi)(shi)同(tong)于不銹鋼絲(si)(si)間(jian)的(de)交(jiao)叉式彎折而(er)產(chan)生應力(li)或磨(mo)擦磨(mo)壞。故使(shi)用性(xing)能(neng)好，能(neng)承(cheng)擔髙壓。
３）高壓膠管的外膠層粘在提高層上起(qi)維(wei)護功效(xiao)，一般選用氯丁膠。應留意避免 其脆化(hua)開裂而危害全部(bu)橡(xiang)膠軟(ruan)管的使(shi)用壽命。
