Mafuta a M8DM. Makhalidwe ndi opanga
Zolemba zamakono
Malinga ndi muyezo GOST 17479.1-2015, M8Dm mafuta amatanthauza lubricant mafuta injini dizilo. Taganizirani makhalidwe aakulu a mafutawa.
- Base. Monga maziko amafuta a injini ya M8Dm, malo oyeretsera kwambiri amchere amagwiritsidwa ntchito, opangidwa kuchokera kumafuta otsika sulfure.
- Zowonjezera. Phukusi lowonjezera ndilokhazikika pamafuta amtunduwu. Calcium idagwiritsidwa ntchito ngati dispersant. Kupititsa patsogolo kupanikizika kwambiri komanso kusamva bwino kwamafuta, zinc ndi phosphorous zimagwiritsidwa ntchito pang'ono.
- kukhuthala kwa kinematic. Pa 100 ° C, kukhuthala kwa mafuta omwe akufunsidwa kuyenera kukhala pakati pa 9,3 ndi 11,5 cSt, yomwe ndi SAE 20 ndi American Society of Automotive Engineers.
- sulfure wamkati. Mafuta amatanthauza low-sulphur, monga momwe akusonyezera ndi index "m" pamutu. Ndiko kuti, madipoziti sludge akagwiritsidwa ntchito ngakhale mu injini sachedwa ndondomeko izi adzakhala ochepa.
- Nambala ya alkaline. Chiwerengerochi chikhoza kusiyana malinga ndi wopanga. Koma nthawi zambiri kuchuluka kwa alkaline kwamafuta a M8Dm kumakhala 8 mgKOH / g. Pafupifupi zizindikiro zofanana za mafuta a M8G2k.
- Pophulikira. Pafupifupi, mafuta amayaka akatenthedwa mu crucible yotseguka ikafika 200 ° C. Apanso, zambiri zimadalira wopanga. Mkhalidwe wofananawo umawonedwa mumafuta am'nyumba a M10G2k, pomwe kung'anima kwenikweni kumatha kusiyanasiyana ndi 15-20 ° C, kutengera yemwe adapanga mafutawo.
- Kuzizira kozizira. Monga lamulo, kwa mafuta otsika kachulukidwe kakang'ono, malo otsanulira ndi okwera kwambiri. Mafuta a M8Dm analinso chimodzimodzi: pafupifupi malo othira ali m'dera la -30 ° C.
Muyezo suchepetsa zizindikiro zambiri zomwe tsopano zimaonedwa kuti ndizofunikira pamafuta agalimoto. Ndipo magawowa amatha kusiyanasiyana kutengera wopanga mafuta.
Chiwerengero cha ntchito
M'matchulidwe a GOST, kuchuluka kwake kumakhudzidwa kwambiri ndi gulu lomwe mafuta a injini ali nawo. Pankhani yazinthu zomwe zikufunsidwa, M8Dm, gulu lamafuta "D" likuwonetsa izi:
- mafuta amatha kugwiritsidwa ntchito mu injini zamafuta okakamizidwa ndi carburetor kapena jekeseni imodzi, koma popanda chothandizira kapena jekeseni wogawa;
- mafuta omwe akufunsidwa ndi oyeneranso ku injini za dizilo zothamanga kwambiri ndi turbine ndi intercooler, koma popanda chosefera, chomwe chimagwira ntchito movutikira kuposa mafuta a gulu G.
M'malo mwake, gawo lalikulu lakugwiritsa ntchito mafutawa ndi magalimoto otaya katundu, makina amigodi, mathirakitala ndi magalimoto okhala ndi injini za dizilo. Nthawi zambiri, mafuta amagwiritsidwa ntchito m'magalimoto opepuka amalonda okhala ndi injini zamafuta. Kumadera akum'mwera, analogue yamafuta awa imagwiritsidwa ntchito: M10Dm.
Muyezo wa boma umapanganso fanizo ndi gulu la API. Mafuta omwe akufunsidwa amafanana ndi kalasi ya CD / SF. Izi ndizochepa, ndipo m'mayiko a Kumadzulo mafuta amtundu uwu tsopano amaonedwa kuti ndi osatha ndipo samapangidwa.
Opanga ndi mitengo
Mafuta a injini ya M8Dm amapangidwa ndi malo angapo opangira mafuta apanyumba.
- Lukoil M8Dm. Amagulitsidwa nthawi zambiri muzitini za malita 18. Mtengo wapakati pa lita imodzi ndi ma ruble 90-100. mbiya ya malita 205 ndalama za 90-95 rubles pa lita.
- Gazpromneft M8Dm. Zimawononga pang'ono, pafupifupi 105-115 rubles pa lita. Mphamvu zambiri ndi 18 malita. Makatani ang'onoang'ono potengera mtengo pa lita imodzi adzakwera kwambiri.
- Naftan M8Dm. Njira yotsika mtengo. Chiyerekezo mtengo - 85-90 rubles pa 1 lita.
- Oilright M8Dm. Mtengo wake ndi wofanana ndi mafuta a Naftan. Komabe, pafupifupi, ngati tilingalira ogulitsa angapo, Oilright M8Dm imawononga pang'ono. Mukhoza kupeza chitini cha malita 20 kwa 1600-1700 rubles. Ndiko kuti, 80-85 rubles pa lita.
Ndemanga za mafuta a injini ya M8Dm nthawi zambiri salowerera ndale. Koma, ngati tilingalira ndemanga za eni ake a zida zomwe zidadzaza mafutawa, ziyenera kugwiritsidwa ntchito pazolinga zake ndipo ndizoyenera kuzisintha nthawi zambiri kuposa momwe zimakhalira ndi malamulo.
