Magalimoto a M8V. Mafuta a injini ya Soviet
Kapangidwe ndi mitundu
Modern galimoto mafuta M8v, ndithudi, si zofanana mu zigawo zake ndi galimoto zaka zana. Komabe, idakhazikitsidwabe pamafuta a petroleum a distillate omwe adachitapo njira yoyeretsera asidi ndikutsatiridwa ndi dewaxing. Izi zimathandiza kuti kusintha kosavuta kwa mamasukidwe akayendedwe, kotero magalimoto nthawi yomweyo m'gulu chilimwe ndi yozizira.
Mafuta a M8v amaphatikizansopo:
- Anti-seiize zowonjezera.
- zotsutsana ndi dzimbiri.
- kutentha stabilizers.
- Zoletsa.
Magalimoto amakono akuphatikizapo mafuta ofanana ndi M8v, omwe amapangidwanso kuti agwiritsidwe ntchito mu injini zamagalimoto ndi zida za thirakitala, makamaka dizilo. Mwachitsanzo, mafuta a M8dm (opangidwa kuchokera ku mafuta owawasa, omwe amagwiritsidwa ntchito mu injini za dizilo zokakamizidwa), kapena mafuta a M10G2k (omwe amagwiritsidwa ntchito pamainjini a dizilo, pomwe kupangika kwa mpweya kumawonjezeka).
Mawonekedwe amafuta a injini ya M8v amawerengedwa kuti ndi kuchuluka kwa kuyeretsedwa panthawi yopanga, ndikuthekera kowonjezera magawo ena a distillate. .
Zolemba zamakono
GOST 10541-78, molingana ndi zofunikira zaumisiri zomwe mtundu wa M8v umapangidwa, umapereka magawo otsatirawa ovomerezeka amafuta:
- Kachulukidwe kutentha firiji, kg/m3: 866.
- Kinematic mamasukidwe akayendedwe osiyanasiyana 100 °C, mm2/ s: 7,5… 8.5.
- Viscosity index: 93.
- Kutentha kwa kuyatsa, ° С, osachepera: 207.
- Kutentha kwakukulu, ° С, osapitirira: -25.
- Kuchuluka kwakukulu kwa zonyansa zamakina, %: 0,015.
- Phulusa la sulfates,%, osaposa: 0,95.
- Alkalinity molingana ndi KOH, mg/l, osati zochepa: 4,2.
Kukhalapo pang'ono mu mafuta a calcium, fluorine ndi zinc cations, komanso anions phosphorous, amaloledwa. Kukhazikika kwa kuwonekera kwa mafuta asanayambe kugwiritsidwa ntchito koyamba kuyenera kusungidwa kwa maola osachepera 30 (kupatulapo ma autols, omwe amapangidwa kuchokera kumafuta ochokera kuminda yaku East Siberian: kwa iwo, kuchuluka kwa sedimentation kumachepetsedwa mpaka maola 25).
Pa pempho lowonjezera la ogula, mawonekedwe a mafuta a M8v amasonyezanso kukhuthala kwake, komwe kuyenera kukhala mumtundu wa 2500 ... 2700 mPa s. Mphamvu mamasukidwe akayendedwe ulamuliro ikuchitika pa kutentha -15 ° C ndi kusiyana wachibale kukameta ubweya mlingo wa moyandikana mbali 4860s.-1.
Zotsatira za ntchito
Ogwiritsa ntchito ambiri agalimoto omwe akufunsidwa amawona kukhazikika kwa mawonekedwe ake, omwe amasintha pang'ono ndikuwonjezeka kwa mtunda wamagalimoto. Iwo ananena kuti M8v mchere mafuta makamaka abwino pa galimoto VAZ banja ntchito m'chilimwe. Kusintha kwamafuta kuyenera kuchitika pambuyo pa 7000 ... 8000 km yothamanga. Chiŵerengero choyenera cha zowonjezera chimachepetsa mpweya wa carbon mu injini.
Mtundu wa Autol M8v umagwirizana ndi gulu la mayiko SAE20W-20. Ma analogue apafupi kwambiri akunja ndi TNK 2t kuchokera ku Lukoil kapena M8G2. Kuchokera kumafuta ochokera kunja - Shell 20W50.
Mtengo pa lita
Zimatsimikiziridwa ndi kuchuluka kwa mafuta mu thanki. Kwa canister yokhala ndi malita 10, mitengo imayamba kuchokera ku ma ruble 800, malita 20 - kuchokera ku ma ruble 2000, mbiya yokhala ndi malita 200 - kuchokera ku ma ruble 16000. Mitengo imasiyananso kutengera wopanga (magalimoto opangidwa m'nyumba, nthawi zambiri amakhala chizindikiro cha Lukoil kapena Gazpromneft).
