Mafuta a dizilo m10dm. Kulekerera ndi makhalidwe

makhalidwe a

The luso makhalidwe mafuta galimoto analamula GOST 17479.1-2015. Komanso, kuwonjezera pa zofunikira za muyezo wa boma, zina zomwe sizinafufuzidwe zimasonyezedwa mosiyana ndi wopanga mafuta.

Pali zinthu zochepa zomwe zimakhala zofunikira kwa wogula ndikuzindikira kugwiritsa ntchito mafuta mu injini inayake.

1. Mafuta owonjezera. M'magulu apakhomo, mafutawa ndi a chilembo choyamba cha chizindikiro. Pankhaniyi, ndi "M", kutanthauza "motor". M10Dm kawirikawiri amapangidwa kuchokera kusakaniza kwa distillate ndi zigawo zotsalira za mafuta a sulfure otsika.
2. Kinematic mamasukidwe akayendedwe kutentha ntchito. Pachikhalidwe, kutentha kwa ntchito ndi 100 ° C. Viscosity sichimalembedwa mwachindunji, koma imasungidwa muzolozera manambala kutsatira chilembo choyamba. Kwa injini yamafuta M10Dm, index iyi, motero, ndi 10. Malinga ndi tebulo kuchokera ku muyezo, kukhuthala kwa mafuta omwe akufunsidwa kuyenera kukhala pakati pa 9,3 mpaka 11,5 cSt. Pankhani ya mamasukidwe akayendedwe, mafutawa amagwirizana ndi muyezo wa SAE J300 30. Monga mafuta ena wamba a injini ya M10G2k.

3. Gulu la mafuta. Uwu ndi mtundu wa gulu la American API, lokhalo losiyana pang'ono. Kalasi "D" pafupifupi imagwirizana ndi muyezo wa CD / SF API. Ndiye kuti, mafuta ndi osavuta ndipo sangathe kugwiritsidwa ntchito mu injini zamakono jekeseni mwachindunji. Kukula kwake ndi injini zamafuta osavuta popanda chothandizira ndi cholumikizira, komanso kukakamiza injini za dizilo zokhala ndi ma turbine, koma opanda zosefera.
4. Phulusa la mafuta. Zimasonyezedwa mosiyana ndi ndondomeko "m" kumapeto kwa dzina malinga ndi GOST. Mafuta a injini ya M10Dm ndi phulusa lochepa, lomwe limakhudza ukhondo wa injini ndipo limapangitsa kuti pakhale kupangika kwa phulusa lolimba (mwaye).
5. Phukusi lowonjezera. Zina mwazosavuta za calcium, zinki ndi phosphorous zinagwiritsidwa ntchito. Mafutawa ali ndi zotsukira zapakatikati komanso kupanikizika kwambiri.

Kutengera wopanga, zinthu zingapo zofunika zomwe zimawonjezedwa kuzizindikiro zamafuta agalimoto a M10Dm.

• Viscosity index. Zimasonyeza momwe mafuta alili okhazikika ponena za kukhuthala ndi kusintha kwa kutentha. Kwa mafuta a M10Dm, chiwerengero cha viscosity index chimachokera ku 90-100 mayunitsi. Ichi ndi chiwerengero chochepa cha mafuta amakono.
• Pophulikira. Akayesedwa mu crucible yotseguka, kutengera wopanga, mafuta amawunikira akatenthedwa mpaka 220-225 ° C. Kukana kwabwino pakuyatsa, komwe kumapangitsa kuti mafuta azigwiritsidwa ntchito pang'onopang'ono.
• Kuzizira kozizira. Opanga ambiri amawongolera njira yotsimikizika yopopera kudzera mudongosolo ndikugwedezeka kotetezeka pa kutentha kwa -18 ° C.
• Nambala ya alkaline. Imatsimikizira mokulirapo kuthekera kochapira ndi kumwaza kwa mafuta, ndiko kuti, momwe mafuta amagwirira ntchito ndi zotayira zamatope. Mafuta a M-10Dm amadziwika ndi nambala yotsika kwambiri, kutengera mtundu, womwe uli pafupifupi 8 mgKOH / g. Pafupifupi zizindikiro zomwezo zimapezeka mumafuta ena wamba: M-8G2k ndi M-8Dm.

Malingana ndi kuphatikiza kwa makhalidwe, tikhoza kunena kuti mafuta omwe akufunsidwa ali ndi kuthekera kwakukulu pamene amagwiritsidwa ntchito mu injini zosavuta. Ndioyenera magalimoto oyendetsa migodi, zofukula, ma bulldozers, mathirakitala okhala ndi madzi okakamizidwa kapena injini zoziziritsa mpweya, komanso magalimoto onyamula anthu ndi magalimoto okhala ndi injini zamafuta okhala ndi injini zopukutidwa popanda makina opangira turbine ndi makina oyeretsera mpweya.

Mtengo ndi kupezeka kwa msika

Mitengo ya mafuta a injini ya M10Dm pamsika waku Russia ndi yosiyana kwambiri malinga ndi wopanga ndi wofalitsa. Timalemba opanga angapo a M10Dm ndikusanthula mitengo yawo.

1. Rosneft M10Dm. 4-lita canister mtengo pafupifupi 300-320 rubles. Ndiko kuti, mtengo wa 1 lita ndi za 70-80 rubles. Imagulitsidwanso mu mtundu wa mbiya, poyika mabotolo.
2. Gazpromneft M10Dm. Njira yokwera mtengo kwambiri. Kutengera voliyumu, mtengo umasiyanasiyana kuchokera ku 90 mpaka 120 rubles pa 1 lita. Zotsika mtengo kugula mu mtundu wa mbiya. Wamba 5-lita canister mtengo 600-650 rubles. Izi ndi pafupifupi 120 rubles pa lita.
3. Lukoil M10Dm. Mtengo wake ndi wofanana ndi mafuta ochokera ku Gazpromneft. Mgolo umasulidwa kuchokera ku ma ruble 90 pa lita imodzi. Mu canisters mtengo umafika 130 rubles pa 1 lita.

Palinso zotsatsa zambiri zamafuta opanda brand pamsika, zomwe zimagulitsidwa kokha ndi dzina la GOST M10Dm. Nthawi zina, sizikugwirizana ndi muyezo. Chifukwa chake, mutha kugula mafuta ofunikira kuchokera ku mbiya kuchokera kwa ogulitsa odalirika.
