Chii viscosity mafuta injini, uye sei zvinokanganisawo kushanda injini

The chikuru basa mafuta injini - kupa usingashandi kukweshera pamusoro injini uchifamba zvikamu. Sezvo motokari injini anoshanda pamusoro navanopinda chaizvo tembiricha siyana, kuti pave noukama kuti kwaizovimbisa optimum waivako pasi zvose kushanda ezvinhu, hazvibviri. Nekuti injini vagadziri Pakusarudza kupfuura rakakodzera inotakura mafuta kuti anopa soro zvaibvira kunyatsoshanda pamwe mudukusa zvaibvira kusakara nhengo pasi zvimwe zvinhu zviri mudzimu injini. Pane weboka mafuta pamusoro "yezhizha" uye "nguva yechando", izvo zvakasiyana kunyanya viscosity.

Zvichitaurwa zviri nyore, kuti viscosity mafuta injini ndozvavava kukwanisa kwayo kuramba pamusoro pemvura workpiece, apo kuramba fluidity. ukoshi ichi hachisi kugara uye zvinoenderana tembiricha. Ashandiswa akasimudza viscosity mafuta injini anokwanisa kuwedzera upenyu basa injini. Sizvo pakusarudza munhu noukama kunotungamirira rokusamhanyira injini kusakara. Kuti kukwanisa neimwe nzira kufamba-siyana lubricants, kuti kupatsanura yakazokudziridzwa. Maererano Russian GOST zvavari akakamurwa:

• chando;
• yezhizha;
• mwaka.

For makirasi zvose kunorondedzerwa kinematic viscosity pa ¹⁰⁰ ° C, uye muchando mwaka uyewo -18 ° ^C. Munyika dzakawanda dzenyika vakagamuchira SAE kupatsanura, kugadzirwa American Society avtoinzhenerov.

Zvinofungidzirwa kuti dzakanga dzakakwirira-tembiricha viscosity mafuta injini, nani. Ichi hachisi chokwadi. Uye kunyange zvazvo yemitambo motokari inokurudzirwa kushandisa viscosity indekisi mafuta injini mukuru, hazvirevi kuti injini wako Bay mune viscous girisi, iwe ndichakuita kubva mureza motokari nakisa mitambo motokari. Injini haizoperi nani. Zvinoitika mumwe nzira kumativi: injini achakurumidza anorasikirwa simba hatingarevi kugadziridza zvikuru kana kunyange kutsiviwa.

Mubhuku basa rine zvikuru akakodzera yenyu gwenya viscosity injini mafuta. Pakusarudza parameter ichi, vagadziri kufungawo zvose zvinobvira modes kushanda ari injini uye zvose zvayo mukuru-nokukurumidza modes. Nekuti zvinoratidza zvikuru Zvakanyanya Kunaka Panguva Yepamuviri parameters ose viscosity.

Kushandisa mafuta akakurira kutya kana viscosity ndiyo anokanganisa muinjini pasi-unongotaura. Yakaderera injini anogona kuzadza viscosity, uye mumwe mukuru mukuru zvazvingava zviri kuramba achishanda yakakwirira tembiricha (nokuti yakawedzera kukweshera), izvo Inowedzera kupfeka. Uyezve, matunhu tembiricha inobatsira kuti kunokurumidza mafuta oxidation, izvo zvinoreva kuti unofanira kuchinja kakawanda. Kushandiswa mukuru-viscosity noukama hakuna zvakadaro nokukurumidza kukanganisa injini oparesheni. Asi chii chichaitika - chaizvo. Naizvozvo, pachiteshi zvinoda kudira mafuta maererano mugadziri wacho vanorumbidza, zvisinei zvaunotaura vashandi vayo: zviri kubatsira yapfuura yacho garandi nguva, iwe pakugadzira motokari yako sezvo kazhinji sezvinobvira. Tarisirawo motokari yako pachako.

Modern injini mafuta muchiso kuchengetedza waivako kwemaawa 500-2000 kuti injini oparesheni, ndiko 12-45 zviuru makiromita. Kuzvitsinhanisa mafuta zvichaitikawo panguva imwe chete shanduko filters uye nokuchengetedza motokari. Panyaya iyi, ari kuramba unhu injini oparesheni zvichagoverwa (akapa kushandiswa varumbidzwa muchiso mugadziri).
