１、橡膠軟管總成
1）高壓(ya)膠管(guan)由內(nei)膠層(ceng)(ceng)、提(ti)高層(ceng)(ceng)和外(wai)膠層(ceng)(ceng)構成（如圖例），內(nei)膠層(ceng)(ceng)立即與液壓(ya)油觸碰，故規(gui)定在(zai)長期性(xing)運(yun)行狀態下不(bu)可受液體浸(jin)蝕，能(neng)補漏。在(zai)提(ti)高層(ceng)(ceng)功效下會承擔一(yi)(yi)定工作壓(ya)力。因(yin)而，宜選用丁腈橡膠，除塑(su)膠粒外(wai)，危害性(xing)能(neng)的(de)(de)關鍵要素(su)也有內(nei)膠層(ceng)(ceng)的(de)(de)強(qiang)(qiang)度、薄厚(hou)和永久(jiu)性(xing)形(xing)變量。強(qiang)(qiang)度和永久(jiu)性(xing)形(xing)變量對密封性(xing)性(xing)能(neng)危害非常(chang)大(da)。一(yi)(yi)般(ban)強(qiang)(qiang)度高、縮(suo)小(xiao)后的(de)(de)永久(jiu)性(xing)形(xing)變量小(xiao)，密封性(xing)性(xing)能(neng)則越好。一(yi)(yi)般(ban)是在(zai)７０～８５邵氏硬度，縮(suo)小(xiao)永久(jiu)性(xing)形(xing)變５０％時。內(nei)膠層(ceng)(ceng)薄厚(hou)建議是為１．５～２．５ｍｍ，太(tai)厚(hou)會在(zai)壓(ya)扣時提(ti)升(sheng)其流動(dong)率，導致不(bu)必要的(de)(de)膠在(zai)接頭芯套與橡膠軟管(guan)的(de)(de)觸碰內(nei)孔內(nei)沉積，減少(shao)商品流通橫截面；過薄會在(zai)壓(ya)扣時被壓(ya)裂。另外(wai)內(nei)膠層(ceng)(ceng)壁(bi)厚(hou)勻(yun)稱性(xing)也很重要。假如薄厚(hou)不(bu)勻(yun)，縮(suo)小(xiao)后會導致一(yi)(yi)面裂斷、一(yi)(yi)面堆膠。內(nei)膠層(ceng)(ceng)表層(ceng)(ceng)出(chu)現(xian)的(de)(de)浮銹(xiu)也是危害性(xing)能(neng)品質的(de)(de)關鍵要素(su)。
２）高壓(ya)(ya)膠(jiao)(jiao)管(guan)關鍵借助提高層(ceng)(ceng)(ceng)(ceng)來承受力(li)。手(shou)工(gong)(gong)編織橡膠(jiao)(jiao)軟管(guan)是(shi)靠膠(jiao)(jiao)漿與(yu)內(nei)外黏膠(jiao)(jiao)粘緊，因(yin)(yin)為(wei)同(tong)一(yi)手(shou)工(gong)(gong)編織層(ceng)(ceng)(ceng)(ceng)內(nei)不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)中(zhong)(zhong)(zhong)間(jian)的(de)(de)互(hu)相(xiang)觸碰(peng)，在(zai)承擔氣(qi)體壓(ya)(ya)力(li)的(de)(de)時(shi)候(hou)會(hui)因(yin)(yin)分別(bie)伸縮(suo)式不(bu)(bu)一(yi)而導(dao)致不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)彼此之間(jian)的(de)(de)摩擦而危害其(qi)使用性能(neng)。而螺旋(xuan)波(bo)紋(wen)管(guan)是(shi)由盤繞方位不(bu)(bu)一(yi)樣的(de)(de)雙(shuang)層(ceng)(ceng)(ceng)(ceng)產生一(yi)個工(gong)(gong)作中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)(ceng)(ceng)中(zhong)(zhong)(zhong)間(jian)有正中(zhong)(zhong)(zhong)間(jian)膠(jiao)(jiao)，因(yin)(yin)而同(tong)一(yi)工(gong)(gong)作中(zhong)(zhong)(zhong)層(ceng)(ceng)(ceng)(ceng)的(de)(de)雙(shuang)層(ceng)(ceng)(ceng)(ceng)不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)中(zhong)(zhong)(zhong)間(jian)沒有交(jiao)接點。因(yin)(yin)此 不(bu)(bu)容易在(zai)承擔氣(qi)體壓(ya)(ya)力(li)時(shi)同(tong)于不(bu)(bu)銹(xiu)鋼(gang)絲(si)(si)間(jian)的(de)(de)交(jiao)叉(cha)式彎(wan)折而產生應(ying)力(li)或磨擦磨壞。故使用性能(neng)好，能(neng)承擔髙壓(ya)(ya)。
３）高(gao)壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層(ceng)(ceng)粘在提(ti)高(gao)層(ceng)(ceng)上起維護(hu)功(gong)效，一般選(xuan)用氯丁(ding)膠(jiao)(jiao)。應(ying)留意避(bi)免 其脆(cui)化開裂而危害全部橡(xiang)膠(jiao)(jiao)軟管的使用壽命。
