Piston masale

Piston mehele - e reng e nang le lekhalo e nyenyane, ha koaloa. Ba ka grooves ka mabota ka ntle tsa pistons ka mefuta eohle ea dienjini piston (tse kang dienjini mouoane , kapa enjene combustion e ka hare).

ke piston masale eng?

1. Ho tiise ka kamoreng go tuka ga molelo. Compression masale eketsa compression ea. Ka zalegshimi, robehileng kapa e tsofetseng masale ke ke qala enjene kapa ho lahleheloa ke matla a.
2. E le hore ho ntlafatsa mocheso phetiso ka marako silindara. Masale le seabo e ka hare combustion e enjene mocheso hana ho tloha piston ho, ka tsela eo ho thibela overheating.
3. E le hore ho fokotsa tshebediso ya oli bakeng sa enjene (ka ba babeli-leqeba disele le tsohle tse 'nè ke seterouku enjene combustion e ka hare).

Kamoo ke piston masale?

Kopanetsoeng (hape ho notlela) e teng pakeng tsa ea lipheletsong tsa piston lesale. Ha piston ka loko silindara e a petetswa hanyenyane - ho dikotwana tse seng kae tsa millimeter ka. Ke oblique (ka mane leqeba hare enjene go tuka ga molelo) le mola o otlolohileng. Masale sebakeng grooves ratang ka tsela e joalo e le hlaha ka lehlakoreng le pakeng tsa manonyeletso ne lekana le (2 mehele - likhato tse 180, masale 3 - 120 likhato). Phello ke labyrinth hore ho fokotsa katleho e kholo khase.

Rings ba eyelet le compression. Eyelet sireletsa kamoreng combustion e ho kena ka oli crankcase. Ba tlosa feteletseng enjene oli tloha silindara sa. Mounted masale eyelet tlase compression. Ba na le ka ho beetsweng. The peli leqeba peterole hare combustion e enjene belofo bakoang ha ba sebelisoa e le oli ho enjene e combusted hammoho mafura. Hona joale ba se hlahisitseng kapa a nyahlatsa tšepe, tšepe kapa lesale le likarolo tse ngata le extenders ka sebōpeho sa liliba. Karolo bonolo le ka tlase bitsa chelete e ngata ho hlahisa, kahoo ba ile ba ba haholo ho tloaelehile hore batho ba fetang lahletseng ka.

Compression piston masale sireletsa crankcase tloha gusts tsa khase e tsoang ka kamoreng go tuka ga molelo. Profinseng nang lesale bophara ntle ho feta ka hare. Ka lebaka lena, e le karolo ea sehlahiswa e khaola. Beha sehiloeng o bitsoa qhobosheaneng. Hangata piston le e mong o behile se fetang tse tharo tsa masale joalo, ka lebaka la hore tekanyo ea ho compaction tsa piston e eketseha hanyenyane, 'me ho lahleheloa khohlano eketseha. Ka tse peli-ke seterouku enjene go tuka ga molelo hare hangata mounted mehele e 'meli. Karolo ea sefapano sa boholo ba masale compression e likhutlo li 'nè ka sebopeho. bohale o na le chamfer e tapered kapa cylindrical profil. Ha hare masale combustion e enjene di sothile ho isa bohōleng bo itseng (e fana ka rengwa ka groove ka a) hore ntsetso-peleng mathang-in.

Tlhahiso ea piston masale

Technology le mekhoa ea ho etsa lokela ho netefatsa hore sebopeho sa sehlahiswa, e le boemong ba lokolohile tla bopa boemo lakatsa la khatello le boemong bo lona sebetsa. The lesale piston hangata entsoe ka tšepe ductile liheloe, kaha e na le ntle elasticity tsitsitseng tshebetso le durability, ho hanyetsa phahameng abrasion, e babatsehang thepa-ba khahlanong le khohlano. dopants a boela a sebelisa (khethehileng barbotage ea chromium porous, molybdenum cladding, ka lero la mali jete nyanyatsoa, ceramic barbotage, taemane likaroloana), e leng eketsa haholo ho mocheso botsitso ba lihlahisoa.
