液壓機操作中如何正確選擇液壓油?

時間: 2023-03-08    作者:admin 點擊: ( 2441 ) 次

液壓機是(shi)依靠(kao)液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)來傳遞動能的(de),液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)選擇的(de)正(zheng)確與否直接關系著液(ye)壓(ya)(ya)(ya)(ya)機(ji)(ji)的(de)性能的(de)發揮。液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)的(de)品牌很多,長城牌、昆侖(lun)牌都是(shi)不(bu)錯的(de)選擇,當然(ran)一定要買真(zhen)牌子的(de)液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you),千萬不(bu)能買便宜的(de)再生油(you)(you)(you)(you),那是(shi)會影(ying)響液(ye)壓(ya)(ya)(ya)(ya)機(ji)(ji)的(de)性能和(he)使用(yong)的(de)。選擇液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you),要根據液(ye)壓(ya)(ya)(ya)(ya)機(ji)(ji)的(de)系統壓(ya)(ya)(ya)(ya)力,液(ye)壓(ya)(ya)(ya)(ya)機(ji)(ji)的(de)工作環境,溫度,選擇不(bu)同型(xing)號(hao)的(de)液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)。

液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)根據基礎(chu)油(you)(you)(you)(you)中(zhong)(zhong)的(de)(de)添加的(de)(de)添加劑成分(fen)的(de)(de)不同,分(fen)為通用液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you),抗(kang)磨液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you),導軌液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you),低溫(wen)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)等。液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)機(ji)(ji)中(zhong)(zhong)若(ruo)系統壓(ya)(ya)(ya)(ya)力<7Mpa,一般選用HL型(xing)通用液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)即(ji)可,若(ruo)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)機(ji)(ji)采用的(de)(de)是柱塞泵或葉片泵等作為動力源,系統的(de)(de)壓(ya)(ya)(ya)(ya)力屬中(zhong)(zhong)、高壓(ya)(ya)(ya)(ya)、重負荷(he),則(ze)系統中(zhong)(zhong)選用的(de)(de)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)就(jiu)應(ying)該是HM型(xing)的(de)(de)抗(kang)磨液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you),這樣才能保證營養系統內精細零部件的(de)(de)正常工(gong)作,若(ruo)是環境溫(wen)度(du)在零度(du)以下(xia)低溫(wen)場(chang)合則(ze)應(ying)該選用HS型(xing)低溫(wen)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)。HV型(xing)低溫(wen)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)使用于比HS型(xing)低溫(wen)液(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)油(you)(you)(you)(you)更低的(de)(de)環境場(chang)合。

即(ji)使是同(tong)一(yi)類液(ye)壓(ya)油(you),鋼木門(men)壓(ya)花機(ji)在不同(tong)的(de)(de)環境溫(wen)度下,也應選用不同(tong)黏度的(de)(de)液(ye)壓(ya)油(you)。動(dong)力(li)粘度是一(yi)個反映液(ye)壓(ya)油(you)流動(dong)性的(de)(de)指標。動(dong)力(li)粘度:是使用單(dan)位距離的(de)(de)單(dan)位面積液(ye)層,產(chan)生(sheng)單(dan)位流速(su)所需(xu)之(zhi)力(li)。單(dan)位:pa.s(帕每秒(miao))。運動(dong)粘度:即(ji)動(dong)力(li)粘度與(yu)密度的(de)(de)比值,習慣單(dan)位為:厘(li)斯。動(dong)力(li)粘度越(yue)小,則低溫(wen)流動(dong)性越(yue)好。L-HM32、L-HM46、L-HM68這三種抗磨液(ye)壓(ya)油(you)是較為常用的(de)(de)型號。

液(ye)壓(ya)(ya)(ya)油(you)(you)的適宜(yi)工(gong)作溫度是(shi)20°C—60°C,鑫岳(yue)機(ji)(ji)床生產的液(ye)壓(ya)(ya)(ya)機(ji)(ji)設備,在油(you)(you)箱中(zhong)(zhong)都(dou)配備水(shui)冷式冷卻器裝置(zhi),液(ye)壓(ya)(ya)(ya)機(ji)(ji)工(gong)作時通(tong)過測溫裝置(zhi)自動(dong)開啟冷卻裝置(zhi)從而達到自動(dong)控(kong)制油(you)(you)溫的功能。因此(ci),美力液(ye)壓(ya)(ya)(ya)機(ji)(ji)一般采(cai)用(yong)L-HM46抗磨液(ye)壓(ya)(ya)(ya)油(you)(you)作為四(si)季液(ye)壓(ya)(ya)(ya)油(you)(you)使(shi)用(yong)。液(ye)壓(ya)(ya)(ya)油(you)(you)中(zhong)(zhong)有固體顆粒物是(shi)不可避免的,我們國家規定,在中(zhong)(zhong)高壓(ya)(ya)(ya)液(ye)壓(ya)(ya)(ya)系統中(zhong)(zhong)對液(ye)壓(ya)(ya)(ya)油(you)(you)的清潔(jie)度要求不應小于NAS 9級(ji)。
