１、橡膠軟管總成
1）高壓(ya)(ya)膠(jiao)(jiao)管由內膠(jiao)(jiao)層(ceng)(ceng)(ceng)、提(ti)高層(ceng)(ceng)(ceng)和(he)外(wai)(wai)膠(jiao)(jiao)層(ceng)(ceng)(ceng)構成(cheng)（如(ru)圖例(li)），內膠(jiao)(jiao)層(ceng)(ceng)(ceng)立即與(yu)液壓(ya)(ya)油觸(chu)碰，故規定在(zai)長期性(xing)(xing)(xing)運行狀態(tai)下不可(ke)受液體浸蝕，能補(bu)漏。在(zai)提(ti)高層(ceng)(ceng)(ceng)功效下會(hui)承擔一定工(gong)作(zuo)壓(ya)(ya)力。因而，宜選用丁(ding)腈橡膠(jiao)(jiao)，除塑膠(jiao)(jiao)粒(li)外(wai)(wai)，危害性(xing)(xing)(xing)能的(de)(de)關鍵要(yao)素(su)也有內膠(jiao)(jiao)層(ceng)(ceng)(ceng)的(de)(de)強度(du)、薄(bo)厚(hou)和(he)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變量(liang)。強度(du)和(he)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變量(liang)對密(mi)封性(xing)(xing)(xing)性(xing)(xing)(xing)能危害非常(chang)大(da)。一般強度(du)高、縮小后的(de)(de)永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變量(liang)小，密(mi)封性(xing)(xing)(xing)性(xing)(xing)(xing)能則(ze)越(yue)好。一般是在(zai)７０～８５邵氏硬度(du)，縮小永(yong)久(jiu)性(xing)(xing)(xing)形(xing)(xing)(xing)變５０％時。內膠(jiao)(jiao)層(ceng)(ceng)(ceng)薄(bo)厚(hou)建(jian)議是為１．５～２．５ｍｍ，太(tai)厚(hou)會(hui)在(zai)壓(ya)(ya)扣時提(ti)升其流動率，導(dao)致(zhi)不必要(yao)的(de)(de)膠(jiao)(jiao)在(zai)接頭芯(xin)套與(yu)橡膠(jiao)(jiao)軟管的(de)(de)觸(chu)碰內孔(kong)內沉積(ji)，減少商品流通橫截面；過薄(bo)會(hui)在(zai)壓(ya)(ya)扣時被壓(ya)(ya)裂。另外(wai)(wai)內膠(jiao)(jiao)層(ceng)(ceng)(ceng)壁厚(hou)勻稱(cheng)性(xing)(xing)(xing)也很重要(yao)。假如(ru)薄(bo)厚(hou)不勻，縮小后會(hui)導(dao)致(zhi)一面裂斷、一面堆膠(jiao)(jiao)。內膠(jiao)(jiao)層(ceng)(ceng)(ceng)表層(ceng)(ceng)(ceng)出現的(de)(de)浮(fu)銹也是危害性(xing)(xing)(xing)能品質的(de)(de)關鍵要(yao)素(su)。
２）高壓膠(jiao)管關鍵借助提高層(ceng)(ceng)來承(cheng)受(shou)力(li)。手工(gong)編織橡(xiang)膠(jiao)軟管是靠膠(jiao)漿(jiang)與內外(wai)黏(nian)膠(jiao)粘緊，因(yin)為同(tong)一手工(gong)編織層(ceng)(ceng)內不(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)間的(de)(de)互相觸碰，在(zai)承(cheng)擔(dan)(dan)(dan)氣(qi)體(ti)(ti)壓力(li)的(de)(de)時(shi)候會(hui)因(yin)分別伸縮(suo)式(shi)不(bu)一而導致不(bu)銹(xiu)鋼(gang)絲彼此之(zhi)間的(de)(de)摩擦(ca)而危(wei)害其(qi)使用性能。而螺(luo)旋波(bo)紋管是由盤(pan)繞方位不(bu)一樣(yang)的(de)(de)雙(shuang)層(ceng)(ceng)產生(sheng)一個工(gong)作中(zhong)(zhong)層(ceng)(ceng)，在(zai)雙(shuang)層(ceng)(ceng)中(zhong)(zhong)間有(you)正中(zhong)(zhong)間膠(jiao)，因(yin)而同(tong)一工(gong)作中(zhong)(zhong)層(ceng)(ceng)的(de)(de)雙(shuang)層(ceng)(ceng)不(bu)銹(xiu)鋼(gang)絲中(zhong)(zhong)間沒(mei)有(you)交接點。因(yin)此 不(bu)容易在(zai)承(cheng)擔(dan)(dan)(dan)氣(qi)體(ti)(ti)壓力(li)時(shi)同(tong)于(yu)不(bu)銹(xiu)鋼(gang)絲間的(de)(de)交叉式(shi)彎(wan)折而產生(sheng)應力(li)或磨擦(ca)磨壞。故使用性能好，能承(cheng)擔(dan)(dan)(dan)髙(gao)壓。
３）高壓膠管(guan)的外(wai)膠層粘在(zai)提高層上起維護功效(xiao)，一般選用(yong)氯丁膠。應留意避免 其脆化開裂而危害全部橡(xiang)膠軟管(guan)的使用(yong)壽命。
