Hydraulic roj VMGZ

Hauv peb lub tebchaws, ntu ntawm cov roj hydraulic yog tsim heev. Thiab ib qho ntawm cov khoom ntawm ntu no yog VMGZ roj. Cov ntawv luv no yog deciphered: "Thickened hydraulic roj rau txhua lub caij." Hom kab no tau nthuav dav hauv peb lub tebchaws. Hydraulic roj ntawm hom no ua hauj lwm nyob rau hauv countless units. Nrov paub nyob rau hauv ntau rooj plaub li VMG peb.

Lub npe raws li GOST

Raws li GOST 17479.3, lub npe no hu ua MG-15-V:

• "MG" - ntxhia hydraulic roj;
• "15" - chav kawm viscosity. Qhov no txhais tau hais tias ntawm 40 ° C lub kinematic viscosity yog 13,50 - 16,50 mm2 / s (cSt)
• "B" - pab pawg ua haujlwm. Qhov no txhais tau hais tias cov muaj pes tsawg leeg muaj xws li ntxhia roj nrog antioxidant, tiv thaiv corrosion thiab tiv thaiv hnav additives. Qhov chaw pom zoo ntawm daim ntawv thov yog hydraulic systems nrog cov twj tso kua mis ntawm txhua hom ntawm lub siab ntawm ntau tshaj 25 MPa thiab roj kub ntawm 90 ° C.

Yam ntxwv, Scopes

VMGZ yog siv los ua cov kua dej hydraulic hauv ntau hom kev tsim khoom, kev tsim kho, kev ua hav zoov, nrog rau txhua qhov chaw uas muaj cov tshuab hydraulic. Qhov no yog vim lub fact tias VMGZ roj muaj ntau yam, nws yog tswj nyob rau hauv kev khiav hauj lwm tej yam kev mob ntawm -35 ° C mus rau +50 ° C, uas tso cai rau cov cav tov ua hauj lwm nyob rau hauv feem ntau ntawm peb lub teb chaws nyob rau hauv lub caij ntuj no thiab lub caij ntuj sov yam tsis muaj qhov xav tau. los hloov cov kua dej hydraulic. Nyob rau hauv tej yam kev mob ntawm central Russia, nws yog pom zoo kom siv nws raws li ib tug caij ntuj no qoob loo. Tsis tas li qhov zoo ntawm hom no yog tias nws tuaj yeem siv los pib hydraulic motors ntawm qhov kub thiab txias.

VMGZ muaj nyob rau hauv peb qhov kev hloov pauv uas txawv ntawm qhov dej taw tes thiab viscosity (qhov qis dua qhov dej taw tes, qhov qis dua qhov viscosity):

• VMGZ-45° N
• VMGZ-55° N
• VMGZ-60° N

Cov neeg tsim khoom tseem ceeb ntawm cov roj VGMZ

Tam sim no, muaj peb lub tuam txhab tsim cov roj tseem ceeb ntawm VMGZ hauv peb lub tebchaws:

1. Gazpromneft
2. Rosneft
3. Lukoil

Lub ntsiab tivthaiv yog cov roj zoo uas tau dhau los ntawm kev xaiv purification thiab muaj cov ntsiab lus sulfur tsawg kawg nkaus. Xws li cov khoom muaj qhov tsis muaj zog viscosity thiab siab tsis zoo ncuav taw tes. Tag nrho lwm yam khoom uas VMGZ hom muaj yog ua tiav los ntawm ntau yam additives uas muab kev tiv thaiv hnav, tiv thaiv ua npuas ncauj, antioxidant thiab corrosion zog.

Muaj nta zoo

• Muab kev tiv thaiv txhim khu kev qha ntawm cov khoom sab hauv tiv thaiv corrosion thiab mechanical hnav;
• Ntau yam nyob rau hauv uas cov kua yog nyob rau hauv kev khiav hauj lwm tej yam kev mob, los ntawm - 35 ° C mus rau + 50 ° C;
• Muaj peev xwm pib lub kaw lus tsis muaj preheating nws;
• Tsis xav tau kev hloov dej hydraulic raws caij nyoog;
• Anti-foam zog pab txo cov kev sib txhuam ntawm cov dej ua haujlwm;

Cov kws tshaj lij cov lus qhia txog kev xaiv thiab kev ua haujlwm

Tsis txhob siv cov VMGZ los yog cov kua dej tsis zoo, thiab ntau dua li tsis paub keeb kwm.

Cov txiaj ntsig ntawm kev ua haujlwm ntawm VMGZ tsis zoo:

1. Qib siab ntawm cov pa phem, sab hauv ntawm hydraulic systems.
2. Lim clogging thiab tsis ua haujlwm.
3. Qib siab ntawm hnav thiab corrosion ntawm cov khoom siv sab hauv.
4. Kev ua tsis tiav vim yog kev sib xyaw ua ke ntawm cov xwm txheej saum toj no.

Cov kws tshaj lij lub tswv yim: Downtime ntawm qee lub tshuab yog kim heev, yog li khaws lub qhov muag ntawm cov dej hydraulic thiab hloov nws raws sijhawm.

Thaum xaiv, ib txwm coj los ntawm cov tuam txhab ntseeg siab. Cov khoom tseem ceeb ntawm VMGZ yuav luag zoo ib yam rau txhua tus neeg tsim khoom. Cov neeg tsim khoom tab tom hloov cov txheej txheem ntawm antioxidant thiab anti-corrosion additives. Ua tib zoo kawm cov muaj pes tsawg leeg thiab xaiv cov roj uas yuav pab koj ua kom lub neej ntawm koj lub tshuab hydraulic. Tsis muaj teeb meem tsis txhob pib ntawm tus nqi.

Ob yam tseem ceeb uas yuav tau xav txog thaum xaiv:

1. Ib txheej ntawm cov khoom uas VMGZ cov roj muab (qhia hauv cov ntaub ntawv qhia kev);
2. Lub koob meej thiab lub hom phiaj txoj cai ntawm cov neeg siv cov tshuab hydraulic;
