Mafuta a Hydraulic VMGZ

M'dziko lathu, gawo lamafuta a hydraulic limapangidwa bwino. Ndipo chimodzi mwa zinthu za gawo ili ndi VMGZ mafuta. Chidule ichi chikuyimira: "Mafuta owonjezera a hydraulic kwa nyengo zonse." Mtundu uwu wafala kwambiri m'dziko lathu. Mafuta a Hydraulic amtunduwu amagwira ntchito pamayunitsi osawerengeka. Nthawi zambiri amadziwika kuti VMG atatu.

Dzina molingana ndi GOST

Malinga ndi GOST 17479.3, mtundu uwu unatchedwa MG-15-V:

• "MG" - mchere hayidiroliki mafuta;
• "15" - kalasi ya mamasukidwe akayendedwe. Izi zikutanthauza kuti pa 40 ° C kinematic viscosity ndi 13,50 - 16,50 mm2 / s (cSt)
• "B" - gulu ntchito. Izi zikutanthauza kuti mafuta amchere amapangidwa ndi antioxidant, anti-corrosion ndi anti-wear additives. Malo omwe akulimbikitsidwa kugwiritsa ntchito ndi makina a hydraulic okhala ndi mapampu amitundu yonse pamphamvu yopitilira 25 MPa ndi kutentha kwamafuta 90 ° C.

Makhalidwe, makulidwe

VMGZ imagwiritsidwa ntchito ngati hydraulic fluid muzopanga zambiri, zomangamanga, nkhalango, komanso m'malo onse omwe ukadaulo wa hydraulic ulipo. Izi ndichifukwa choti mafuta a VMGZ ndi osinthika kwambiri, amasungidwa m'malo ogwiritsira ntchito kuyambira -35 ° С mpaka +50 ° С, zomwe zimalola makina kuti azigwira ntchito m'madera ambiri a dziko lathu nthawi yozizira ndi chilimwe popanda kufunikira. kusintha madzimadzi amadzimadzi. M'madera aku Central Russia, tikulimbikitsidwa kuti tigwiritse ntchito ngati mbewu yozizira. Komanso mwayi waukulu wamtunduwu ndikuti ungagwiritsidwe ntchito kuyambitsa ma hydraulic motors pa kutentha kochepa.

VMGZ imapezeka m'mitundu itatu yomwe imasiyana pakutsanulira ndi kukhuthala (kutsika kothira, kutsitsa mamasukidwe):

• VMGZ-45°N
• VMGZ-55°N
• VMGZ-60°N

Opanga ndi matekinoloje opanga

Opanga kwambiri mafuta VGMZ

Pakadali pano, m'dziko lathu pali mabizinesi atatu akuluakulu opanga mafuta a VMGZ:

1. Gazpromneft
2. Rosneft
3. Lukoil

Chigawo chachikulu ndi mafuta abwino omwe ayeretsedwa mwapadera ndipo amakhala ndi sulfure yochepa. Zigawo zotere zimakhala ndi viscosity yotsika komanso kutsanulira koyipa kwambiri. Zina zonse zomwe mtundu wa VMGZ uli nazo zimatheka kudzera pazowonjezera zosiyanasiyana zomwe zimapereka anti-wear, anti-foam, antioxidant ndi corrosion properties.

NKHANI ZABWINO

• Amapereka chitetezo chodalirika cha ziwalo zamkati motsutsana ndi dzimbiri ndi zovala zamakina;
• Zosiyanasiyana zomwe madzi amakhalapo pansi pazigwiritsidwe ntchito, kuchokera -35 ° С mpaka + 50 ° С;
• Kutha kuyambitsa dongosolo popanda kutenthetsa;
• Palibe chifukwa chosinthira ma hydraulic fluid fluid;
• Anti-foam katundu amathandiza kuchepetsa kukangana kwa madzimadzi ogwira ntchito;

Malangizo a akatswiri pa kusankha ndi ntchito

Osagwiritsa ntchito VMGZ kapena madzi otsika, komanso osadziwika bwino.

Zotsatira za ntchito ya VMGZ yotsika:

1. Mkulu mlingo wa kuipitsa, mbali zamkati za ma hydraulic systems.
2. Sefa kutsekeka ndi kulephera.
3. Kuvala kwakukulu ndi dzimbiri kwa zigawo zamkati.
4. Kulephera chifukwa cha zinthu zomwe zili pamwambazi.

Lingaliro la akatswiri: Kupuma pamakina ena ndi okwera mtengo kwambiri, choncho yang'anirani momwe madzi amadzimadzi amakhalira ndikusintha munthawi yake.

Posankha, nthawi zonse tengani kuchokera kwa opanga odalirika. The katundu waukulu VMGZ ndi pafupifupi ofanana kwa opanga onse. Opanga akusintha seti ya antioxidant ndi anti-corrosion zowonjezera. Phunzirani mosamala kapangidwe kake ndikusankha mafuta omwe angakuthandizeni kukulitsa moyo wama hydraulic system. Mulimonsemo musayambe pamtengo.

Zinthu ziwiri zofunika kuziganizira posankha:

1. Seti ya katundu kuti VMGZ mafuta amapereka (zinasonyezedwa mu zolembedwa luso);
2. Kutchuka ndi ulamuliro wamtundu pakati pa ogwiritsa ntchito ma hydraulic systems;
