１、橡膠軟管總成
1）高壓(ya)膠(jiao)(jiao)(jiao)(jiao)管由內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)和(he)(he)外膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)構成（如(ru)圖例(li)），內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)立即(ji)與液壓(ya)油觸碰，故規定在(zai)長期性(xing)(xing)運(yun)行(xing)狀態下(xia)不可(ke)受液體浸(jin)蝕，能(neng)補(bu)漏(lou)。在(zai)提(ti)高層(ceng)(ceng)(ceng)功效(xiao)下(xia)會承擔一(yi)定工作壓(ya)力。因(yin)而，宜選用(yong)丁腈(jing)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)，除塑膠(jiao)(jiao)(jiao)(jiao)粒外，危(wei)(wei)害性(xing)(xing)能(neng)的(de)關鍵要素也有內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)強(qiang)度、薄(bo)厚和(he)(he)永久(jiu)(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)量。強(qiang)度和(he)(he)永久(jiu)(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)量對密封(feng)(feng)性(xing)(xing)性(xing)(xing)能(neng)危(wei)(wei)害非常大。一(yi)般(ban)強(qiang)度高、縮小后的(de)永久(jiu)(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)量小，密封(feng)(feng)性(xing)(xing)性(xing)(xing)能(neng)則越好。一(yi)般(ban)是(shi)在(zai)７０～８５邵(shao)氏(shi)硬度，縮小永久(jiu)(jiu)性(xing)(xing)形(xing)(xing)變(bian)(bian)５０％時。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚建(jian)議是(shi)為１．５～２．５ｍｍ，太(tai)厚會在(zai)壓(ya)扣時提(ti)升(sheng)其(qi)流(liu)動率，導致不必要的(de)膠(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套(tao)與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)軟管的(de)觸碰內(nei)(nei)(nei)孔內(nei)(nei)(nei)沉積，減少商品(pin)流(liu)通橫截面；過薄(bo)會在(zai)壓(ya)扣時被壓(ya)裂。另外內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚勻稱性(xing)(xing)也很(hen)重(zhong)要。假如(ru)薄(bo)厚不勻，縮小后會導致一(yi)面裂斷、一(yi)面堆膠(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)浮銹也是(shi)危(wei)(wei)害性(xing)(xing)能(neng)品(pin)質的(de)關鍵要素。
２）高壓(ya)膠(jiao)管(guan)關鍵(jian)借助提高層(ceng)來承受(shou)力(li)(li)(li)(li)。手(shou)(shou)工(gong)(gong)編(bian)(bian)織(zhi)橡膠(jiao)軟(ruan)管(guan)是(shi)(shi)靠膠(jiao)漿與內(nei)外黏膠(jiao)粘緊(jin)，因(yin)為(wei)同(tong)一(yi)手(shou)(shou)工(gong)(gong)編(bian)(bian)織(zhi)層(ceng)內(nei)不(bu)(bu)(bu)(bu)(bu)(bu)銹鋼(gang)絲(si)中(zhong)間(jian)(jian)的(de)(de)互相(xiang)觸碰(peng)，在承擔(dan)氣體(ti)壓(ya)力(li)(li)(li)(li)的(de)(de)時候會(hui)因(yin)分別伸縮(suo)式(shi)不(bu)(bu)(bu)(bu)(bu)(bu)一(yi)而(er)(er)導致不(bu)(bu)(bu)(bu)(bu)(bu)銹鋼(gang)絲(si)彼此(ci)之間(jian)(jian)的(de)(de)摩擦而(er)(er)危害(hai)其使用性能(neng)(neng)。而(er)(er)螺旋波紋管(guan)是(shi)(shi)由盤繞方位不(bu)(bu)(bu)(bu)(bu)(bu)一(yi)樣的(de)(de)雙層(ceng)產(chan)生(sheng)一(yi)個工(gong)(gong)作中(zhong)層(ceng)，在雙層(ceng)中(zhong)間(jian)(jian)有正中(zhong)間(jian)(jian)膠(jiao)，因(yin)而(er)(er)同(tong)一(yi)工(gong)(gong)作中(zhong)層(ceng)的(de)(de)雙層(ceng)不(bu)(bu)(bu)(bu)(bu)(bu)銹鋼(gang)絲(si)中(zhong)間(jian)(jian)沒有交(jiao)接點。因(yin)此(ci) 不(bu)(bu)(bu)(bu)(bu)(bu)容易在承擔(dan)氣體(ti)壓(ya)力(li)(li)(li)(li)時同(tong)于不(bu)(bu)(bu)(bu)(bu)(bu)銹鋼(gang)絲(si)間(jian)(jian)的(de)(de)交(jiao)叉(cha)式(shi)彎折而(er)(er)產(chan)生(sheng)應力(li)(li)(li)(li)或磨擦磨壞。故使用性能(neng)(neng)好，能(neng)(neng)承擔(dan)髙壓(ya)。
３）高壓膠(jiao)管的外(wai)膠(jiao)層粘在提高層上(shang)起(qi)維護功效，一般選用(yong)氯丁膠(jiao)。應留意避免 其脆化開裂而危害全(quan)部橡膠(jiao)軟管的使用(yong)壽命(ming)。
