Turbo bearing ke eng? Mefuta ea li-turbocharged bearing

Ho bea turboke bearing e ka har'a turbocharger, ho utloisisa turbocharger, pele re hloka ho tseba turbocharger le likarolo tsa eona tse tsamaeang.

 

Turbocharger efe?

Turbocharger, eo re e fumanang hangata likoloing, ha e le hantle ke compressor ea moea e hatellang moea ho eketsa bongata ba moea o kenang. E sebelisa inertial impulse ea khase ea mosi e ntšitsoeng ke enjene ho sutumelletsa turbine ka kamoreng ea turbine, 'me turbine e khanna coaxial impeller, 'me impeller e hatella moea o rometsoeng ke phaephe ea sefe ea moea ho o hatella ka har'a silindara. Ha lebelo la enjene le eketseha, lebelo la ho ntša khase ea mosi le lebelo la turbine le tsona lia eketseha ka nako e le 'ngoe, impeller e hatella moea o mongata ka har'a silindara, khatello le bongata ba moea li ka chesa mafura a mangata, tsa eketsa bongata ba mafura le ho fetola lebelo la enjene, u ka eketsa matla a tlhahiso ea enjene.

 

Likarolo tse tsamaeang tsa turbocharger ke life?

Likarolo tse tsamaeang tsa turbocharger le tsona ke likarolo tsa mantlha - lebili la turbine, impeller ea compressor le shaft ea rotor, 'me ntlo ea supercharger e na le motsamao o potlakileng haholo, e leng ntho e sa mamelleheng bakeng sa li-bearing tse tloaelehileng, kahoo bearing ea supercharger ke bearing e ikhethang e phaphametseng.

 

Ha e le hantle ke lesale la koporo le tlamilweng ka matsoho hodima shaft le ntlo, ka dibaka tse pakeng tsa lesale le shaft le pakeng tsa lesale le ntlo. Ha enjene e sebetsa, tlasa kgatello ya oli, filimi ya oli e habeli e boptjwa dikarolong tsena, mme rotor e hlile e phaphamala hodima filimi ya oli mme e potoloha ka lebelo le phahameng.

 

Ka lebaka la lebelo le phahameng haholo la ho potoloha le mocheso o phahameng haholo, sebaka sena se boetse se beha tlhoko e phahameng haholo ea ho tlotsa le ho pholisa.

 

Haeba supercharger e sa tlotsoa hantle ebile e sa phodiswa, e tla baka ho tsofala ho sa tloaelehang ha bearing, e khutsufatse haholo bophelo ba ts'ebeletso ea bearing, e eketse lekhalo pakeng tsa rotor le ntlo, 'me karolo ea oli e tla kena phaepheng ea ho kenella kapa phaephe ea ho ntša mosi ho tsoa karolong ena, e leng se fellang ka ho hloleha ho hoholo ha ho chesa oli.

 

Mefuta ealibere tse nang le turbocharged

Jwalo ka karolo ya bohlokwa e tsamayang ya turbocharger, sebopeho sa bearing se amana le ho tshepahala le ho tshwarella ha turbine. Ho na le mefuta e mmedi e meholo ya dibearing tsa turbocharger, e nngwe ke dibearing tse phaphametseng mme e nngwe ke dibearing tsa bolo.

 

Hona jwale, boholo ba bahlahisi ba baholo ba dikoloi ba sebedisa di-floating bearings, tse lokelang ho ba tse tshwarellang le tse theko e tlase. Di-floating bearings ha e le hantle ke lesale hodima shaft, mme ho na le lekhalo pakeng tsa lesale le shaft le pakeng tsa lesale le shaft e behetsweng, e leng se etsang filimi ya oli e habeli. Lesale le phaphamala pakeng tsa shaft le shaft. Ka kakaretso, lekhalo la kahare la lera le ka bang 0.05mm, mme lekhalo la kantle la lera le ka bang 0.1mm. Botenya ba lebota la bearing ke hoo e ka bang 3.0-4.5mm, mme le entswe ka alloy ya boronse ya tin-lead, mme bokahodimo ba bearing bo manehilwe ka lera la alloy ya lead-tin kapa indium ya tshepe e nang le botenya ba hoo e ka bang 0.005-0.008mm. Ha supercharger e sebetsa, bearing e potoloha pakeng tsa shaft le shaft. Ka hona, re ka fumana mathata a di-floating bearings: kganyetso e phahameng ya ho matha ha di-turbine shafts, kgatello e phahameng ya oli le ditlhoko tsa boleng, le taolo e sa tsitsang ya matla a di-turbine shafts.

 

Li-bearing tsa bolo li fumanoa haholo likoloing tse sebetsang, 'me joalo ka ha lebitso le bontša, li-bearing tsa bolo ke sebaka sa ho kenya libolo ho turbine shaft ho nkela oli sebakeng sa bearing e phaphametseng. Molemo oa li-bearing tsa bolo ke ntho e fapaneng hantle le li-bearing tse phaphametseng: khohlano e fokolang, hysteresis e tlase ea turbine, 'me e molemo haholo bakeng sa ho hatella meeli e matla; Matla a turbine shaft a ka laoloa ka katleho; Khatello ea oli le boleng li ka fokotsoa hanyane, e leng se eketsang bophelo ba turbine ka tsela e sa tobang. Mefokolo ea eona le eona e totobetse, ke hore, bophelo ha bo botle joaloka bearing e phaphametseng, ka kakaretso lik'hilomithara tse 70,000 ho isa ho tse 80,000 ho ea moeling oa bophelo, 'me litšenyehelo tsa tlhokomelo li theko e boima, tlhokomelo e thata. Leha ho le joalo, ka lebaka la ho hohela li-bearing tsa bolo mabapi le matla, e ntse e le lisebelisoa tse ka sehloohong likoloing tse sebetsang.
