【中板(ban)豎拼機(ji)拼板(ban)機(ji)膠(jiao)合板(ban)設(she)備廠(chang)家介紹】液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)的(de)(de)(de)(de)用(yong)(yong)途。液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)用(yong)(yong)途廣(guang)泛，是工(gong)業用(yong)(yong)油(you)(you)中使用(yong)(yong)最多(duo)的(de)(de)(de)(de)產(chan)品(pin)(pin)。當前液(ye)壓(ya)(ya)(ya)(ya)元件正向著體積小(xiao)、功率大(da)(da)方向發(fa)展(zhan)，系統壓(ya)(ya)(ya)(ya)力越(yue)來越(yue)高(gao)，有(you)的(de)(de)(de)(de)已突破50MPa。為此，普通型(xing)(xing)的(de)(de)(de)(de)L-HL系列(lie)已經趨(qu)于(yu)(yu)淘汰，抗磨型(xing)(xing)L-HM系列(lie)應用(yong)(yong)更(geng)多(duo)。低溫(wen)性(xing)能(neng)也是液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)的(de)(de)(de)(de)重要(yao)(yao)特性(xing)，要(yao)(yao)求在低溫(wen)環境下設(she)備啟(qi)動(dong)比較容易，且動(dong)力傳動(dong)靈敏，而(er)且液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)換油(you)(you)周期(qi)較長(chang)，如露天(tian)設(she)備通常一(yi)年(nian)一(yi)換，液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)在使用(yong)(yong)過(guo)程(cheng)中不(bu)(bu)可(ke)避免(mian)地要(yao)(yao)經歷四季的(de)(de)(de)(de)變化，因(yin)此露天(tian)設(she)備使用(yong)(yong)低凝產(chan)品(pin)(pin)效(xiao)果較好。清(qing)(qing)潔(jie)度(du)也已成(cheng)為液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)的(de)(de)(de)(de)性(xing)能(neng)要(yao)(yao)求，一(yi)般產(chan)品(pin)(pin)要(yao)(yao)NAS顆(ke)粒度(du)等(deng)級不(bu)(bu)大(da)(da)于(yu)(yu)9級，清(qing)(qing)潔(jie)型(xing)(xing)產(chan)品(pin)(pin)不(bu)(bu)大(da)(da)于(yu)(yu)7級，高(gao)清(qing)(qing)潔(jie)型(xing)(xing)產(chan)品(pin)(pin)不(bu)(bu)大(da)(da)于(yu)(yu)5級，但盲(mang)目追求NAS等(deng)級不(bu)(bu)但沒有(you)任何(he)效(xiao)果，反而(er)降低質量，增加(jia)成(cheng)本(ben)。例如有(you)些機(ji)械生產(chan)廠(chang)家，或工(gong)程(cheng)機(ji)械用(yong)(yong)戶沒有(you)用(yong)(yong)于(yu)(yu)添加(jia)液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)的(de)(de)(de)(de)無塵(chen)車間，即(ji)使花了(le)(le)大(da)(da)價錢購買了(le)(le)NAS 5級別的(de)(de)(de)(de)產(chan)品(pin)(pin)，在打(da)開產(chan)品(pin)(pin)的(de)(de)(de)(de)瞬間，高(gao)清(qing)(qing)潔(jie)型(xing)(xing)NAS 5 液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)就變成(cheng)了(le)(le)NAS 8的(de)(de)(de)(de)等(deng)級了(le)(le)，而(er)且液(ye)壓(ya)(ya)(ya)(ya)油(you)(you)NAS等(deng)級高(gao)意味(wei)著過(guo)濾次數(shu)多(duo)，過(guo)濾過(guo)程(cheng)中就會把昂(ang)貴(gui)的(de)(de)(de)(de)添加(jia)劑成(cheng)分過(guo)濾掉，因(yin)此從專業的(de)(de)(de)(de)角度(du)來講，NAS等(deng)級不(bu)(bu)必過(guo)于(yu)(yu)追求。
