Molao-motheo oa ts'ebetso le moralo oa li-compensators tsa hydraulic valve

Likarolo tsa kabo ea khase ea enjene li tlas'a meroalo e boima le mocheso o phahameng nakong ea ts'ebetso. Li atoloha ka mokhoa o sa tsitsang ha li futhumatsoa hobane li entsoe ka li-alloys tse fapaneng. Ho theha ts'ebetso e tloaelehileng ea li-valve, moqapi o tlameha ho fana ka lekhalo le khethehileng la mocheso pakeng tsa bona le lik'hamera tsa camshaft, tse koalang ha enjene e sebetsa.

Lekhalo le tlameha ho lula le le ka har'a meeli e behiloeng, kahoo li-valve li tlameha ho fetoloa nako le nako, ke hore, khetha li-pusher kapa li-washer tsa boholo bo loketseng. Li-compensator tsa hydraulic li u lumella ho tlosa tlhokahalo ea ho fetola lekhalo la mocheso le ho fokotsa lerata ha enjene e bata.

Moralo oa compensator ea Hydraulic

Li-compensator tsa Hydraulic li lokisa ka bo eona phetoho ea lekhalo la mocheso. Sehlomathiso "hydro" se bolela ketso ea mokelikeli o itseng ts'ebetsong ea sehlahisoa. Mokelikeli ona ke oli e fanoang tlas'a khatello ho li-comensator. Sistimi e tsoetseng pele le e nepahetseng ea selemo ka hare e laola ho hlaka.

Tšebeliso ea li-hydraulic lifters e na le melemo e latelang:

• ha ho hlokahale hore ho be le phetoho ea nako le nako ea li-valve;
• ts'ebetso e nepahetseng ea nako;
• ho fokotsa lerata nakong ea ts'ebetso ea enjene;
• ho eketseha ha mohlodi wa metjhini ya kabo ya kgase.

Likarolo tsa mantlha tsa compensator ea hydraulic ke:

• matlo;
• Plunger kapa plunger para;
• plunger bushing;
• selemo sa plunger;
• valve ea plunger (bolo).

Kamoo li-hydraulic lifters li sebetsang kateng

Ts'ebetso ea sesebelisoa e ka hlalosoa ka mekhahlelo e mengata:

• Khamera ea camshaft ha e fane ka khatello ho compensator 'me e shebane le eona ka lehlakoreng la eona le ka morao, e nang le lekhalo le lenyenyane pakeng tsa bona. Seliba sa plunger se ka hare ho compensator se sutumelletsa plunger ka ntle ho letsoho. Ka nako ena, ho bōptjoa sekoti tlas'a plunger, e tletseng oli tlas'a khatello ka mocha o kopantsoeng le lesoba 'meleng. Molumo oa oli o tlatsitsoe ho ea boemong bo hlokahalang 'me valve ea bolo e koetsoe ke seliba. The pusher e phomola khahlanong le cam, motsamao oa plunger o emisa mme mocha oa oli oa koala. Tabeng ena, lekhalo le nyamela.
• Ha cam e qala ho reteleha, e tobetsa "hydraulic compensator" ebe e e theola. Ka lebaka la bongata bo bokelletsoeng ba oli, para ea plunger e fetoha e thata 'me e fetisetsa matla ho valve. Belofo ea khatello ea bula 'me motsoako oa mafura a moea o kena ka kamoreng ea mollo.
• Ha e theoha, oli e 'ngoe e tsoa ka har'a sekoti tlas'a plunger. Ka mor'a hore cam e fetise mohato o sebetsang oa tšusumetso, potoloho ea ho sebetsa e phetoa hape.

Compensator ea hydraulic e boetse e laola lekhalo le bakoang ke ho apara ha tlhaho ha likarolo tsa nako. Ena ke mokhoa o bonolo, empa ka nako e ts'oanang o rarahaneng oa ho etsa ka mokhoa o nepahetseng oa likarolo.

Ts'ebetso e nepahetseng ea li-hydraulic lifters haholo e ipapisitse le khatello ea oli tsamaisong le viscosity ea eona. Oli ea viscous haholo le e batang e ke ke ea khona ho kena 'meleng oa pusher ka chelete e hlokahalang. Khatello e tlaase le ho lutla ho boetse ho fokotsa katleho ea mochine.

Mefuta ea li-compensator tsa hydraulic

Ho latela lisebelisoa tsa nako, ho na le mefuta e mene ea mantlha ea li-hydraulic lifter:

• li-hydraulic pushers;
• li-roller hydraulic pushers;
• tšehetso ea hydro;
• litšehetso tsa hydraulic tse kentsoeng ka tlas'a matsoho a rocker kapa levers.

Mefuta eohle e na le moralo o fapaneng hanyane, empa o na le molao-motheo o ts'oanang oa ts'ebetso. Tse tloaelehileng ka ho fetisisa likoloing tsa morao-rao ke li-tappets tse tloaelehileng tsa hydraulic tse nang le tšehetso e bataletseng bakeng sa camshaft cam. Mekhoa ena e kenngoa ka ho toba holim'a stem ea valve. Camshaft cam e sebetsa ka kotloloho ho hydraulic pusher.

Ha camshaft e le boemong bo tlaase, litšehetso tsa hydraulic li kenngoa tlas'a levers le matsoho a rocker. Tokisetsong ena, cam e sutumelletsa mochine ho tloha ka tlaase 'me matla a fetisetsoa ho valve ka letsoho kapa letsoho la rocker.

Li-roller hydro bearings li sebetsa ka molao-motheo o tšoanang. Lirolara tse kopanang le likamera li sebelisoa ho fokotsa likhohlano. Li-roller hydraulic bearings li sebelisoa haholo lienjineng tsa Majapane.

Melemo le Boipheliso

Li-compensator tsa hydraulic li thibela mathata a mangata a tekheniki nakong ea ts'ebetso ea enjene. Ha ho hlokahale ho lokisa lekhalo la mocheso, mohlala ka li-washer. Litheipi tsa Hydraulic li boetse li fokotsa lerata le meroalo e tšosang. Ts'ebetso e bonolo le e nepahetseng e fokotsa ho senyeha ha likarolo tsa nako.

Har'a melemo ho boetse ho na le go tlhoka mesola. Li-engines tse nang le li-compensator tsa hydraulic li na le litšobotsi tsa tsona. Ntho e totobetseng ka ho fetisisa ho tsena ke ts'ebetso e sa lekaneng ea enjene e batang ha e qala. Ho na le litšobotsi tse kokotang tse nyamelang ha mocheso le khatello li fihleloa. Sena se bakoa ke khatello e sa lekaneng ea oli qalong. Ha e kene ho compensator, kahoo ho kokota.

Bothata bo bong ke litšenyehelo tsa likarolo le litšebeletso. Haeba ho hlokahala ho e nkela sebaka, e lokela ho behoa ho setsebi. Li-compensator tsa Hydraulic le tsona li batla boleng ba oli le ts'ebetso ea sistimi eohle ea lubrication. Haeba u sebelisa oli ea boleng bo tlaase, joale sena se ka ama ts'ebetso ea bona ka ho toba.

Mafunction a ka bang teng le lisosa tsa ona

Ho kokota ka sephetho ho bontša ho se sebetse hantle ha mochine oa ho aba khase. Haeba ho na le manonyeletso a katoloso ea hydraulic, lebaka e ka ba:

• Ho se sebetse hantle ha li-hydraulic pushers ka botsona - ho hloleha ha li-plunger kapa ho jamming ha li-plungers, ho thinya ha valve ea bolo, ho roala ha tlhaho;
• Khatello e tlaase ea oli tsamaisong;
• Liphasejene tsa oli li koalehile hloohong ea silinda;
• Moea o tsamaisong ea lubrication.

Ho ka ba thata haholo ho mokhanni ea tloaelehileng ho fumana mochine o lokisang marapo o fosahetseng. Ho etsa sena, ka mohlala, u ka sebelisa stethoscope ea koloi. Ho lekane ho mamela motho e mong le e mong oa hydraulic lifti ho tseba se senyehileng ka mokhoa oa sona oa ho kokota.

Ho phaella moo, o ka hlahloba ts'ebetso ea li-compensator, u ka khona, haeba ho khoneha, u li tlose ho tloha enjene. Ha lia lokela ho honyela ha li tlatsitsoe. Mefuta e meng e ka aroloa 'me tekanyo ea ho apara ea likarolo tse ka hare e ka khethoa.

Oli ea boleng bo tlase e lebisa liphasejeng tsa oli tse koalehileng. Sena se ka lokisoa ka ho fetola oli ka boeona, sefahla sa oli le ho hloekisa li-hydraulic lifters ka botsona. E ka hlatsuoa ka metsi a khethehileng, acetone kapa high-octane peterole. Ha e le oli, haeba bothata bo le ho eona, joale ka mor'a ho e fetola, sena se lokela ho thusa ho felisa ho kokota.

Litsebi li khothalletsa hore u se ke ua nkela li-compensators ka bomong, empa hang-hang. Sena se tlameha ho etsoa ka mor'a lik'hilomithara tse likete tse 150-200. Ha li le bohōle bona, li khathala ka tlhaho.

Ha o nkela li-compensator tsa hydraulic, ho lokela ho nahanoa ka lintlha tse ling:

• Litheipi tse ncha tsa hydraulic li se li tlatsitsoe ka oli. Oli ena ha e hloke ho tlosoa. Oli e kopantsoe tsamaisong ea lubrication mme moea ha o kene tsamaisong;
• Ka mor'a ho hlatsoa kapa ho qhaqhoa, li-compensator "tse se nang letho" (tse se nang oli) ha lia lokela ho kenngoa. Ke kamoo moea o ka kenang tsamaisong;
• Kamora ho kenya li-compensator tse ncha tsa hydraulic, ho kgothaletswa ho potoloha crankshaft ka makhetlo a 'maloa. Sena sea hlokahala e le hore lipara tsa plunger li kene boemong ba ho sebetsa 'me khatello e eketsehe;
• Ka mor'a ho nkela li-compensator sebaka, ho kgothaletswa ho fetola oli le filthara.

Ho thibela manonyeletso a ho atolosoa ha haeteroliki hore a se ke a baka mathata a seng makae kamoo ho ka khonehang nakong ea ts'ebetso, sebelisa oli ea boleng bo holimo e khothaletsoang bukeng ea buka ea mong'a koloi. Hape hoa hlokahala ho latela melao ea ho fetola oli le li-filters. Haeba litlhahiso tsena li lateloa, li-hydraulic lifters li tla nka nako e telele.
