１、橡膠軟管總成
1）高(gao)(gao)(gao)壓(ya)膠(jiao)(jiao)管(guan)由內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)、提(ti)高(gao)(gao)(gao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)和外(wai)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)構成（如圖例），內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)立即與液壓(ya)油觸(chu)碰(peng)，故規定在長期性(xing)(xing)運行狀態下不可受液體(ti)浸蝕，能(neng)(neng)補漏(lou)。在提(ti)高(gao)(gao)(gao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)功效下會(hui)承擔(dan)一(yi)(yi)定工作壓(ya)力(li)。因而(er)，宜選用丁腈橡膠(jiao)(jiao)，除(chu)塑膠(jiao)(jiao)粒外(wai)，危(wei)害性(xing)(xing)能(neng)(neng)的關鍵要(yao)(yao)素(su)也有(you)內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)的強(qiang)度、薄(bo)厚(hou)(hou)(hou)和永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)(bian)量。強(qiang)度和永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)(bian)量對密(mi)封性(xing)(xing)性(xing)(xing)能(neng)(neng)危(wei)害非常大。一(yi)(yi)般(ban)強(qiang)度高(gao)(gao)(gao)、縮小(xiao)后(hou)的永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)(bian)量小(xiao)，密(mi)封性(xing)(xing)性(xing)(xing)能(neng)(neng)則(ze)越好。一(yi)(yi)般(ban)是在７０～８５邵氏(shi)硬(ying)度，縮小(xiao)永(yong)久(jiu)性(xing)(xing)形(xing)變(bian)(bian)５０％時。內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)薄(bo)厚(hou)(hou)(hou)建議是為(wei)１．５～２．５ｍｍ，太(tai)厚(hou)(hou)(hou)會(hui)在壓(ya)扣時提(ti)升其流動率(lv)，導致不必要(yao)(yao)的膠(jiao)(jiao)在接頭芯套與橡膠(jiao)(jiao)軟管(guan)的觸(chu)碰(peng)內(nei)(nei)孔內(nei)(nei)沉積，減少商品流通橫截(jie)面；過薄(bo)會(hui)在壓(ya)扣時被壓(ya)裂(lie)。另外(wai)內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)壁厚(hou)(hou)(hou)勻稱性(xing)(xing)也很(hen)重要(yao)(yao)。假如薄(bo)厚(hou)(hou)(hou)不勻，縮小(xiao)后(hou)會(hui)導致一(yi)(yi)面裂(lie)斷、一(yi)(yi)面堆膠(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)(ceng)(ceng)出(chu)現的浮(fu)銹(xiu)也是危(wei)害性(xing)(xing)能(neng)(neng)品質的關鍵要(yao)(yao)素(su)。
２）高(gao)壓膠管關鍵借助提高(gao)層(ceng)來承(cheng)受力(li)。手(shou)工編織橡膠軟管是(shi)靠膠漿與內外(wai)黏(nian)膠粘緊，因(yin)為(wei)同(tong)一(yi)手(shou)工編織層(ceng)內不(bu)(bu)銹(xiu)鋼(gang)絲(si)中(zhong)(zhong)間(jian)的(de)互相觸(chu)碰(peng)，在承(cheng)擔(dan)氣體(ti)壓力(li)的(de)時(shi)候會因(yin)分別伸縮式(shi)不(bu)(bu)一(yi)而(er)(er)(er)導(dao)致不(bu)(bu)銹(xiu)鋼(gang)絲(si)彼此(ci)之間(jian)的(de)摩擦而(er)(er)(er)危害(hai)其使用性(xing)能(neng)。而(er)(er)(er)螺旋波紋管是(shi)由盤繞方位不(bu)(bu)一(yi)樣的(de)雙(shuang)(shuang)層(ceng)產生一(yi)個工作中(zhong)(zhong)層(ceng)，在雙(shuang)(shuang)層(ceng)中(zhong)(zhong)間(jian)有正中(zhong)(zhong)間(jian)膠，因(yin)而(er)(er)(er)同(tong)一(yi)工作中(zhong)(zhong)層(ceng)的(de)雙(shuang)(shuang)層(ceng)不(bu)(bu)銹(xiu)鋼(gang)絲(si)中(zhong)(zhong)間(jian)沒有交(jiao)接點(dian)。因(yin)此(ci) 不(bu)(bu)容易在承(cheng)擔(dan)氣體(ti)壓力(li)時(shi)同(tong)于不(bu)(bu)銹(xiu)鋼(gang)絲(si)間(jian)的(de)交(jiao)叉式(shi)彎折而(er)(er)(er)產生應力(li)或磨擦磨壞。故使用性(xing)能(neng)好，能(neng)承(cheng)擔(dan)髙壓。
３）高壓膠(jiao)管的外膠(jiao)層粘在提高層上(shang)起維護功效，一般(ban)選用(yong)氯丁(ding)膠(jiao)。應留意避(bi)免 其脆化開裂而(er)危害全部橡膠(jiao)軟管的使用(yong)壽命。
