１、橡膠軟管總成
1）高壓(ya)(ya)膠(jiao)(jiao)(jiao)(jiao)(jiao)管由(you)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)、提高層(ceng)(ceng)(ceng)(ceng)(ceng)和(he)外(wai)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)構(gou)成（如(ru)圖例），內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)立即與液壓(ya)(ya)油觸(chu)碰，故規定(ding)在(zai)長期性(xing)(xing)運行狀態下不可受液體浸蝕，能(neng)補(bu)漏。在(zai)提高層(ceng)(ceng)(ceng)(ceng)(ceng)功效下會(hui)承擔一(yi)定(ding)工作(zuo)壓(ya)(ya)力。因而，宜(yi)選用丁腈(jing)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)，除塑(su)膠(jiao)(jiao)(jiao)(jiao)(jiao)粒外(wai)，危害性(xing)(xing)能(neng)的(de)(de)關鍵要(yao)(yao)素也有(you)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)的(de)(de)強(qiang)度、薄(bo)厚(hou)(hou)和(he)永(yong)久(jiu)性(xing)(xing)形(xing)(xing)(xing)變(bian)量(liang)。強(qiang)度和(he)永(yong)久(jiu)性(xing)(xing)形(xing)(xing)(xing)變(bian)量(liang)對密封性(xing)(xing)性(xing)(xing)能(neng)危害非常大。一(yi)般強(qiang)度高、縮小(xiao)后的(de)(de)永(yong)久(jiu)性(xing)(xing)形(xing)(xing)(xing)變(bian)量(liang)小(xiao)，密封性(xing)(xing)性(xing)(xing)能(neng)則越(yue)好。一(yi)般是在(zai)７０～８５邵氏硬度，縮小(xiao)永(yong)久(jiu)性(xing)(xing)形(xing)(xing)(xing)變(bian)５０％時。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)薄(bo)厚(hou)(hou)建議是為(wei)１．５～２．５ｍｍ，太厚(hou)(hou)會(hui)在(zai)壓(ya)(ya)扣時提升其流動(dong)率(lv)，導致(zhi)不必要(yao)(yao)的(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)在(zai)接頭芯套與橡(xiang)膠(jiao)(jiao)(jiao)(jiao)(jiao)軟管的(de)(de)觸(chu)碰內(nei)(nei)孔內(nei)(nei)沉積，減少商(shang)品流通(tong)橫截面；過薄(bo)會(hui)在(zai)壓(ya)(ya)扣時被壓(ya)(ya)裂。另外(wai)內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)壁厚(hou)(hou)勻(yun)(yun)稱性(xing)(xing)也很重要(yao)(yao)。假如(ru)薄(bo)厚(hou)(hou)不勻(yun)(yun)，縮小(xiao)后會(hui)導致(zhi)一(yi)面裂斷、一(yi)面堆膠(jiao)(jiao)(jiao)(jiao)(jiao)。內(nei)(nei)膠(jiao)(jiao)(jiao)(jiao)(jiao)層(ceng)(ceng)(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)(ceng)(ceng)出現(xian)的(de)(de)浮銹也是危害性(xing)(xing)能(neng)品質的(de)(de)關鍵要(yao)(yao)素。
２）高壓膠(jiao)(jiao)(jiao)(jiao)管關鍵借助提(ti)高層(ceng)來承(cheng)受力(li)。手工(gong)編織橡膠(jiao)(jiao)(jiao)(jiao)軟管是(shi)靠膠(jiao)(jiao)(jiao)(jiao)漿與內(nei)外黏(nian)膠(jiao)(jiao)(jiao)(jiao)粘緊，因(yin)為同一(yi)手工(gong)編織層(ceng)內(nei)不(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間(jian)的(de)(de)(de)互(hu)相(xiang)觸碰，在(zai)承(cheng)擔氣(qi)體(ti)壓力(li)的(de)(de)(de)時候會因(yin)分(fen)別(bie)伸縮式(shi)不(bu)一(yi)而(er)導致不(bu)銹鋼(gang)絲(si)彼此之間(jian)的(de)(de)(de)摩擦而(er)危害其使用性能。而(er)螺旋(xuan)波紋管是(shi)由盤繞(rao)方位不(bu)一(yi)樣的(de)(de)(de)雙(shuang)層(ceng)產生(sheng)(sheng)一(yi)個(ge)工(gong)作中(zhong)(zhong)層(ceng)，在(zai)雙(shuang)層(ceng)中(zhong)(zhong)間(jian)有正中(zhong)(zhong)間(jian)膠(jiao)(jiao)(jiao)(jiao)，因(yin)而(er)同一(yi)工(gong)作中(zhong)(zhong)層(ceng)的(de)(de)(de)雙(shuang)層(ceng)不(bu)銹鋼(gang)絲(si)中(zhong)(zhong)間(jian)沒有交接(jie)點。因(yin)此 不(bu)容易在(zai)承(cheng)擔氣(qi)體(ti)壓力(li)時同于不(bu)銹鋼(gang)絲(si)間(jian)的(de)(de)(de)交叉式(shi)彎(wan)折而(er)產生(sheng)(sheng)應(ying)力(li)或磨擦磨壞(huai)。故使用性能好(hao)，能承(cheng)擔髙(gao)壓。
３）高壓膠(jiao)(jiao)管的外膠(jiao)(jiao)層粘在(zai)提高層上起維護功效，一(yi)般選(xuan)用(yong)(yong)氯丁膠(jiao)(jiao)。應留意避免 其脆化開裂而危害全部橡膠(jiao)(jiao)軟管的使用(yong)(yong)壽命(ming)。
