VMGZ decoding - hydraulic mafuta

Nthawi zambiri, mafuta a VMGZ amagwiritsidwa ntchito ngati madzi opangira ma hydraulic. Kufotokozera kwa dzina ili: mafuta ochulukirapo a hydraulic okhuthala.

Kugwiritsa ntchito mafuta a VMGZ

Mafuta a VMGZ amagwiritsidwa ntchito pamakina owongolera ma hydraulic, komanso ma hydraulic abulusa mumitundu iyi ya zida:

• Zida zapadera za msewu
• Zida zonyamulira ndi zoyendera
• Makina omanga
• Zida zankhalango
• Magalimoto osiyanasiyana omwe amatsata

Kugwiritsiridwa ntchito kwa VMGZ kumatsimikizira kudalirika kwa ntchito ya chipangizo chamakono, komanso chiyambi cha hydraulic drive pa kutentha kwambiri kwa mpweya.

Chofunikira kwambiri chamafuta awa ndikuti safunikira kusinthidwa pogwira ntchito munyengo zosiyanasiyana. Mafuta ndi oyenera kugwira ntchito pa kutentha kuchokera -35 ° C mpaka + 50 ° C, malingana ndi mtundu wa mpope wogwiritsidwa ntchito mu dongosolo.

Makhalidwe luso mafuta VMGZ

Popanga mafutawa, zigawo za mchere zocheperako zomwe zimakhala ndi ma viscosity ocheperako zimagwiritsidwa ntchito ngati zopangira. Zigawozi zimachokera ku tizigawo ta petroleum pogwiritsa ntchito hydrocracking kapena phula lakuya. Ndipo mothandizidwa ndi zowonjezera zosiyanasiyana ndi zowonjezera, mafuta amabweretsedwa ku kugwirizana komwe kukufunikira. Mitundu yowonjezera yowonjezera ku VMGZ mafuta: antifoam, antiwear, antioxidant.

Mafuta a Hydraulic amawonetsa mafuta abwino kwambiri, osatulutsa thovu, chinthu chofunikirachi chimathandizira kuti mafuta asatayike panthawi yogwira ntchito. Komanso, mankhwalawa amalimbana ndi mvula, yomwe imakhala ndi zotsatira zabwino pa kulimba kwa makinawo. Zogulitsazi zimakhala ndi anti-corrosion properties ndipo zadzipanga ngati njira yabwino kwambiri yotetezera zitsulo. Chimodzi mwazinthu zofunika kwambiri ndikutha kuyambitsa makina popanda kutentha mafuta.

Mawonekedwe amafuta a VMGZ:

• Kukhuthala kosachepera 10 m / s pa 50 ° С
• Viscosity osapitirira 1500 pa 40 ° С
• Viscosity index 160
• Kuwala pa t osatsika kuposa 135 ° С
• kuumitsa t -60 ° С
• Zonyansa zamakina siziloledwa
• Palibe madzi ololedwa
• Mafutawo ayenera kukhala osagwirizana ndi dzimbiri zachitsulo
• Kachulukidwe osapitirira 865 kg / m³ pa 20 ° C
• Kuchuluka kwa matope sikudutsa 0,05% ya unyinji wonse

Opanga mafuta VMGZ

Opanga kutsogolera mafuta amenewa ndi makampani 4 lalikulu: Lukoil, Gazpromneft, Sintoil, TNK.

Ambiri mwa ogula mafuta awa amapereka kusankha mokomera makampani Lukoil ndi Gazprom. Pali malingaliro amphamvu pakati pa ogwira ntchito ndi oyendetsa zida zapadera kuti mafuta a hydraulic amakampaniwa amapangidwa pazida zomwezo kuchokera kuzigawo zomwezo zamafuta.

Mutha kumvanso mayankho olakwika okhudza mitengo yamafuta a hydraulic ochokera kunja, mwachitsanzo, mafuta osavuta a Mobil amawononga nthawi 2-3 kuposa VMGZ kuchokera kwa opanga zoweta.

Kulekerera ndi gawo lofunikira pakusankha mafuta a hydraulic, komanso posankha mafuta a injini yagalimoto.

Posankha mafuta a hydraulic, ndikofunikira kusankha chinthu chabwino, apo ayi, pamodzi ndi mafuta otsika a VMGZ, amapezanso zovuta zingapo:

• Kuchuluka kwa kuipitsidwa kwa ma hydraulics
• Zosefera zotsekeka
• Inapita patsogolo kuvala ndi dzimbiri mbali

Zotsatira zake, nthawi yocheperako imachitika pantchito yokonza kapena kupanga, zomwe zimatengera mtengo wokwera kwambiri kuposa kusiyana kwamtengo pakati pamafuta apamwamba ndi zabodza zotsika mtengo.

Chovuta chachikulu posankha wopanga VMGZ ndi pafupifupi kufanana kwamafuta ochokera kwa opanga osiyanasiyana. Izi ndichifukwa chazowonjezera zazing'ono zomwe makampani onse amagwiritsa ntchito. Panthawi imodzimodziyo, kuyesa kupambana pa mpikisano, aliyense wa makampani opanga adzayang'ana zinthu zina za mafuta, ngakhale kuti sizikusiyana ndi mpikisano.

Pomaliza

VMGZ mafuta ndi irreplaceable mnzake wa zimango hayidiroliki. Komabe, muyenera kuyandikila mosamala kusankha mafuta ndi kuganizira mbali zotsatirazi:

• Posankha, ndikofunika kuti muphunzire mosamala ndondomeko ya makina a hydraulic kuti mudziwe zomwe kulekerera kwa mafuta kumaperekedwa mu makina awa.
• Ndikofunikira kuyang'ana mafuta motsutsana ndi miyezo ya ISO ndi SAE
• Posankha mafuta a VMGZ, mtengo sungakhoze kuonedwa ngati muyeso waukulu, izi zikhoza kukhala ndalama zokayikitsa.

Mafuta a Hydraulic LUKOIL VMGZ

Mafunso ndi Mayankho:

Kodi mafuta a Vmgz amawerengedwa bwanji? Ndi mafuta ochulukirapo a hydraulic hydraulic. Mafutawa sapanga matope, omwe amalola kugwiritsa ntchito njira panja.

Mafuta a Vmgz amagwiritsidwa ntchito bwanji? Mafuta a hydraulic hydraulic awa amagwiritsidwa ntchito pazida zomwe zimagwira ntchito panja: kumanga, kudula mitengo, kukweza ndi kunyamula, etc.

Kodi kukhuthala kwa Vmgz ndi chiyani? Pa kutentha kwa madigiri +40, kukhuthala kwa mafuta kumachokera ku 13.5 mpaka 16.5 sq.mm / s. Chifukwa cha izi, imasungabe katundu wake pazovuta mpaka 25 MPa.
