Chii mafuta uye lubricants

Maererano unconfirmed mishumo, lubricants anoshandiswa murume anopfuura zviuru 6. Makore akapfuura. Mafuta yave kuzivikanwa kwenguva refu, asi kurishandisa yayo yakaisvonaka chimiro achiri ichangopfuura, asi kubudiswa kutaura uye asingadi kuenda. Kana vanhu vakadzidza kuti ironge nayo, ipapo isu vakanonga chete reparafini, sezvo chinokosha - mafuta - yaishandiswa huni, kana kungoti kupiswa. Uye zviri 90% kubudikidza kurema mafuta zvinokosha.

Asi zvemichina hazvirevi mira - uye zvino painocheneserwa vakadzidza kuparadzanisa mafuta kuva zvikamu zviduku zvakasiyana. Tevera kurapwa ikabereka mafuta anokosha kubva, akashevedza mafuta kana zvicherwa. In injini ano mota - yakakwirira zvokuimba kupisa mutoro, saka lubricants kwavari inofanira kusvitsa zvimwe zvinodiwa.

Kuvandudza mamwe lubricating mafuta nokushandisa kuwedzera kwachiri tiine zvinhu (yokuvirisa). Mumwe nomumwe yokuvirisa izvi anovandudza indices imwe kana pakawanda. Somuenzaniso, protivoiznosostoykie chirungiso akawedzera lubricants kuderedza padanho kusakara yokushanda zvikamu, uye kuchenesa - kuderedza uwandu deposits uye kudzivirira pisitoni mhete isanamira. Modern lubricating mafuta kuverenga anopfuura gumi okuwedzera.

Aine siyana yokuvirisa uye mukana chokubatanidza navo uye kuwedzera kuwanda, izvo vanopa vagadziri. Izvi lubricating mafuta zvavakanga inongomutsa. Uye kunze, paivawo vashoma yavo chipfuro rudzi - injini, hutachiwana uye nezvimwewo. lubricating anonhuwirira (kunyange rinozivikanwa mugadziri) Asati vanotenga kuziva dzinokosha aanozvisarudzira.

Lubricants vane parameters zhinji raanotaura zvekushandisa unhu, asi pamwe kuritenga zvinokosha kuti unyatsoteerera chete kune vaviri. mafuta yepamusoro pamwero inoratidza kugarisana motokari yako iyi, uye viscosity - suitability raro kushandiswa mune imwe okunze uye mwaka.

Kusarudza kuti ndiye noukama kuchabatsira nyora vaivapo mamakisi chero zvokutenga, pamwe chete pose Indexing hurongwa. The zvinorondedzerwa zvemichina mhiri kwemakungwa mitemo uye tsanangudzo yakanatsa viscosity indekisi maererano nzira vagamuchirwa neAmerican Society of Automotive Engineers SAE, saka wafungidzira kuti viscosity zvichabviswa sezvinoratidzwa pashure chiratidzo SAE tsamba. Runotaurwa tsamba W chando mamakisi pakati rinochiwedzera uye lubricants, uye chirimo - nyore chinoratidza viscosity.

Panewo mwero notation. Somuenzaniso, pasi rokuti SAE J300 akavanda mumakirasi mitanhatu viscosity yechando muoti - 0W, 5W, 10W, 15W, 20W, 25W. makirasi zvose izvi zviri anosimbiswa tatanga muchina iri kuchitonhora ezvinhu, uye kufamba peturu uye lubricants kuchiitika pachena yose ezvinhu ari tembiricha siyana -30- + 5 inegumi. Summer mhando havana imwe tsamba kupenda, asi pamwe nokuwedzera viscosity emarudzi aya rakakamurwa makirasi SAE 20, 30, 40, 50, 60.

Zvino kuti munoziva chinotsva uye lubricants, uye chii kupatsanura kwavo!
