Kodi kukhuthala kwa mafuta injini, ndi mmene machitidwe a injini

Ntchito yaikulu ya mafuta injini - kupereka mikangano kochepa olimbana kusuntha mbali. Popeza injini galimoto ntchito pa lonse kutentha osiyanasiyana, kulenga lubricant kuti kuti anaonetsetsa ntchito akadakwanitsira m'mikhalidwe zonse zikugwira ntchito, sikutheka. Chifukwa opanga injini kudziŵa ambiri abwino kalasi mafuta kuti kupereka zotheka Mwachangu apamwamba ndi wamng'ono zotheka mbali avale akamaziwononga cha machitidwe a galimoto ndi. Pali gulu la lubricant pa "chilimwe" ndi "yozizira," womwe amasiyana makamaka kukhuthala.

Kunena mwachidule, kukhuthala mafuta injini amadziwika umatha kukhala pamwamba pa workpiece ndi popitiriza fluidity. Khalidwe limeneli si nthawi zonse ndipo zimadalira kutentha. Molondola anatola kukhuthala mafuta injini akhoza kutalikitsa moyo utumiki wa galimoto ndi. Pachithunzichi kusankha lubricant ndi kumabweretsa msanga injini avale. Kuti athe mwanjira kuyenda osiyanasiyana lubricants, gulu la anayamba kupanga. Malinga ndi GOST Russian iwo anawagawa:

• yozizira;
• chilimwe;
• nyengo.

Kwa magulu onse kumatanthauza ndi kukhuthala kinematic pa ¹⁰⁰ ° C, ndi nyengo yozizira komanso pa -18 ° ^C. M'mayiko ambiri a dziko anatenga SAE gulu, anayamba ndi American Society avtoinzhenerov.

Akukhulupirira kuti apamwamba mkulu-kutentha kukhuthala kwa mafuta injini bwino. Izi siziri zoona. Ndipo ngakhale galimoto masewera akulimbikitsidwa kugwiritsa ntchito mkulu kukhuthala index mafuta injini, sizitanthauza kuti injini yanu Bay mu mafuta viscous mudzasangalatsa pa muyezo galimoto galimoto wapamwamba masewera. mota sadzakhala kuthamanga bwino. Zimachitika njira zina mozungulira: injini mwamsanga kutaya mphamvu ndipo amafuna kukonza yaikulu kapena kusinthanitsa.

M'buku utumiki muli abwino kwambiri kwa mafuta galimoto kukhuthala injini yanu. Kudziwa chizindikiro ichi, opanga kuganizira modes zotheka zonse ntchito injini ndipo onse modes ake mkulu-liwiro. Chifukwa kumasonyeza magawo ambiri mulingo woyenera kwambiri kukhuthala.

Ntchito mafuta mopitirira kapena pansi-ntchito kukhuthala chimawononga injini. Pa otsika injini akhoza kuononga kukhuthala, ndipo pa mlingo mkulu izo nthawi zonse ntchito pa kutentha okwera (chifukwa cha mikangano), zomwe Iyamba kuvala. Komanso, kutentha zimathandiza kuti othamanga mafuta makutidwe ndi okosijeni, kutanthauza kuti muyenera kusintha zambiri. Ntchito yapamwamba-kukhuthala lubricant si posachedwa bwanji injini ntchito. Koma zimene zidzachitike - chimodzimodzi. Choncho, pamalopa amafuna mafuta malinga ndi malangizo Mlengi, kaya zimene mukunena antchito ake: n'kwabwino kwa atapita nthawi chitsimikizo, inu anakonza galimoto yanu monga Nthawi zambiri. Kusamalira galimoto yanu nokha.

Modern galimoto mafuta mtundu kukhalabe ntchito kwa maola 500-2000 ntchito injini, ndiko 12-45 zikwi makilomita. M'MALO lubricant Padzakhala nthawi imodzi ndi kusintha kwa Zosefera ndi kukonza galimoto. Mu nkhani iyi, mosalekeza khalidwe injini ntchito adzam'patsa zosowa (anapereka ntchito analimbikitsa mtundu wopanga).
