　　機(ji)床液(ye)壓(ya)系統中使用的(de)油管(guan)，有鋼管(guan)、銅管(guan)、尼龍(long)管(guan)、橡膠軟(ruan)(ruan)管(guan)和塑料管(guan)等多種(zhong)，它們應根(gen)據(ju)連接元件的(de)相(xiang)對位(wei)置、使用環境(jing)和工作(zuo)壓(ya)力來進(jin)行選擇(ze)。

　　銅管(guan)(guan)、鋼管(guan)(guan)和尼龍(long)管(guan)(guan)屬于(yu)(yu)硬管(guan)(guan)，用(yong)(yong)于(yu)(yu)連接相(xiang)對位里(li)不(bu)變的(de)(de)固(gu)定元件。鋼管(guan)(guan)能(neng)(neng)承(cheng)受高(gao)壓(ya)，價格(ge)便宜(yi)，耐(nai)(nai)油、抗腐蝕和剛性都較(jiao)(jiao)好。但(dan)(dan)裝配(pei)(pei)中不(bu)能(neng)(neng)任意(yi)彎(wan)曲(qu)(qu)，常用(yong)(yong)于(yu)(yu)裝配(pei)(pei)方便的(de)(de)壓(ya)力(li)(li)管(guan)(guan)道處(chu)。紫鋼管(guan)(guan)彎(wan)曲(qu)(qu)比較(jiao)(jiao)方便，由于(yu)(yu)剛度小(xiao)在裝配(pei)(pei)時還可有(you)小(xiao)量變形，故便于(yu)(yu)裝配(pei)(pei)但(dan)(dan)承(cheng)壓(ya)能(neng)(neng)力(li)(li)低，價格(ge)也貴，抗展能(neng)(neng)力(li)(li)弱又易使(shi)油液氧化(hua)，應盡量少用(yong)(yong)。黃銅管(guan)(guan)承(cheng)壓(ya)能(neng)(neng)力(li)(li)較(jiao)(jiao)高(gao)，但(dan)(dan)彎(wan)曲(qu)(qu)較(jiao)(jiao)難。尼龍(long)管(guan)(guan)的(de)(de)耐(nai)(nai)壓(ya)能(neng)(neng)力(li)(li)好，在油中加熱到160-170℃就能(neng)(neng)隨意(yi)彎(wan)曲(qu)(qu)，實際生產中多用(yong)(yong)來作回(hui)油管(guan)(guan)。

　　橡(xiang)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)、塑料軟(ruan)(ruan)(ruan)管(guan)(guan)常(chang)用(yong)(yong)于(yu)兩個相(xiang)對運(yun)動(dong)元件之(zhi)間(jian)的連接。橡(xiang)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)分高壓(ya)(ya)和(he)低(di)(di)壓(ya)(ya)兩種。高壓(ya)(ya)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)是在(zai)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)中(zhong)間(jian)加一層或幾層編織(zhi)(zhi)鋼(gang)絲(si)而成(cheng)，其承壓(ya)(ya)能(neng)力高。低(di)(di)壓(ya)(ya)橡(xiang)膠(jiao)(jiao)(jiao)(jiao)管(guan)(guan)則以編織(zhi)(zhi)棉、麻線代(dai)替編織(zhi)(zhi)鋼(gang)絲(si)，多用(yong)(yong)于(yu)低(di)(di)壓(ya)(ya)回(hui)油管(guan)(guan)道(dao)。軟(ruan)(ruan)(ruan)管(guan)(guan)的彎曲(qu)半徑應(ying)大于(yu)9倍外徑，至(zhi)少應(ying)在(zai)離(li)接頭6倍直(zhi)徑處彎曲(qu)，因此軟(ruan)(ruan)(ruan)管(guan)(guan)所占空(kong)間(jian)大。在(zai)液壓(ya)(ya)缸和(he)調(diao)速閥(fa)之(zhi)間(jian)不宜(yi)接軟(ruan)(ruan)(ruan)管(guan)(guan)，否則運(yun)動(dong)部件容(rong)易(yi)產生爬行(xing)。
