Phahamiso ea Valve ea Hydraulic: Ts'ebetso, Tlhokomelo le Theko

Nomoro E bohlokoa bakeng sa ts'ebetso e nepahetseng ea enjene ea hau, li-hydraulic valve lifters li netefatsa khokahano lipakeng tsa camshaft le li-valve ka ketso ea cam. Li na le likamore tse peli tseo oli ea enjene e hatelloang ho tsona.

🚗 Phahamiso ea haeteroliki e sebelisetsoa eng?

Le hydraulic lift karolo ea koloi e u lumellang hore u tlamecamshaft и di-valve koloi. Ho na le mefuta e fapaneng ea li-valve tsa hydraulic valve, empa hangata li na le likamore tse peli tse bolokang khatello ea oli ea enjene.

Ha e le hantle, kamore e ka holimo e ntse e kopana le camshaft 'me e slide ka kamoreng e ka tlaase e kopanang le camshaft. kutu ea valve... Likamore tse peli li buisana ka mocha o nang le valve ea ho laola khatello.

Kahoo, ha hydraulic valve lifter e phomotse ka hona tla ha e hatelle ho eona, likamore tse peli li lelekoa ke khatello ea oli e potolohang ka valve. Ka hona, ha ho na papali pakeng tsa cam le valve.

Ka lehlakoreng le leng, ha mochini o phahamisang li-valve tsa haeteroliki o sebetsa 'me ka hona cam e hatella khahlanong le eona ho bula valve, valve e koala ebe e thibela kamore e ka holimo hore e se ke ea thella ka phaposing e ka tlase ka lebaka la khatello ea oli. Belofo ea haeteroliki e hatella valve ho e bula.

???? Matšoao a HS hydraulic valve lifter ke afe?

Haeba hydraulic pushers hao tshoaroa ou e nang le sekodike moo o tla utlwa ho opa matsoho enjene.

Haeba molumo oa ho tobetsa o hlaha feela ha ho bata 'me o nyamela ha ho chesa, ho joalo ho hlokomela ho tsoa oli ea baeti. Joale u ka sebelisa setlolo se ikhethileng ka har'a oli ea hau ho lokolla li-valve tsa haeteroliki.

Haeba molumo oa ho tobetsa o phehella le ha o chesa, ha ho pelaelo hore bothata ke bona valve e nang le phoso... Ka mor'a moo, o tla tlameha ho fetola li-tappets tsa hydraulic.

Keletso ea koloi : Ho lelefatsa bophelo ba hydraulic valve lifter, ho kgothaletswa ho sebedisa feela boleng le oli e amohelehang ya enjene. Hape hopola ho fetola oli khafetsa ho qoba ho koala enjene le li-valve tsa haeteroliki.

🔧 Mokhoa oa ho fetola li-valve tsa hydraulic?

Ho nkela sebaka sa hydraulic valve lifter ke ts'ebetso e rarahaneng e hlokang ho qhaqha koloi. Ntle le haeba o na le lisebelisoa tse nepahetseng kapa o le setsebi sa mechini, ha re khothaletse hore u fetole phahamiso ea hydraulic valve ka bouena.

Lintho tse hlokahalang:

• Liatlana tse sireletsang
• Likhalase tse sireletsang
• Lisebelisoa tse felletseng
• sehokedi
• Wrench ea torque
• Oli ea mochini

Mohato oa 1: Beha enjene ho setsi sa bafu holimo (TDC).

Top dead center e bontša boemo boo piston e fihlang sebakeng se phahameng ka ho fetisisa sa stroke ea eona ka silindara. Sebelisa lebili la letsoho ho fumana boemo ba lipiston tsa hau.

Ho fetola boemo ba li-piston, kenya lisebelisoa tsa 3rd, ebe u phahamisa lebili ka jack 'me qetellong u fetole lebili ho ea ka nako. Joale u tla bona kamoo matsoho a rocker a sebetsang kateng 'me li-piston li tsamaea. Phetla ho fihlela piston ea pele e le holimo.

Mohato oa 2. Tlosa lebanta la nako.

Tlosa lebanta la nako ho pulley ea camshaft ka ho lokolla tensioner pulley. Ho etsa sena, o tla hloka ho tlosa molebeli oa lebanta.

Mohato oa 3: Tlosa sekoahelo sa cylinder.

Hlakola linate tse sireletsang sekoahelo sa cylinder 'me u se tlose. Hlokomela hore u se ke ua lahleheloa kapa ua senya cylinder head gasket haeba u lakatsa ho e sebelisa hape.

Mohato oa 4: Tlosa camshaft.

Hlakola linate tse behang li le peli ka nako, butle-butle u li lokolle e le 'ngoe ka nako. Se ke oa khoasolla boutu e le 'ngoe ka ho felletseng ntle le haeba e 'ngoe e le metsi. Ka mor'a ho tlosa li-bolts, li-bearings le camshaft li ka tlosoa.

Hlokomela : Hlokomela hore u se ke ua kopanya li-bering kaha li tlameha ho bokelloa ka tatellano e nepahetseng. Ka sebele, mekhahlelo e baloa.

Mohato oa 5: Kenya sebaka sa lifti ea hydraulic valve e nang le bothata

Kaha joale camshaft e se e tlositsoe, qetellong u ka tlosa li-valve tsa hydraulic tse nang le phoso 'me u li nkele sebaka ka lisebelisoa tse ncha tsa hydraulic valve lifters. Etsa bonnete ba hore u qoelisa li-valve tse ncha tsa hydraulic ka har'a oli ho li tlatsa hape pele u li kenya.

Beha li-hydraulic valve lifters karolong e amanang le cam ho thibela ho tsoa ha oli le ho tsoa ha valve.

Mohato oa 6. Bokella likarolo tse sa tšoaneng tsa enjene.

Hang ha lipompo tse ncha tsa hydraulic li se li le teng, u ka khutlisa mehato ea ho kopanya hape. Sebelisa sekontiri sa torque ho tiisa torque e nepahetseng.

Ka mor'a ho kopanya ntho e 'ngoe le e' ngoe, tlohela enjene e sa sebetse nako e ka bang metsotso e leshome le metso e mehlano ho hloekisa moea ho tsoa ho liphahamisi tsa hydraulic valve. Hape hopola ho hlahloba boemo ba oli ea enjene.

Ke hona, liphahamiso tsa hau tsa hydraulic valve li se li nketsoe sebaka! Haeba enjene e tsoela pele ho opa ho sa tsotellehe hore na ke eng, e ka ba hobane pompo ea oli ha e hlahise khatello e lekaneng.

Lengolo : Kaha u tla ba le monyetla oa ho kena ka hare ho enjene ho fetola li-tappets tsa valve, ho kgothaletswa hore o nke monyetla wa ho nkela sebaka sa cylinder head cover gasket, tensioner roller, camshaft oil seal le lebanta la nako ka nako e le nngwe ha ho hlokahala. .

???? Ho bitsa bokae ho khutlisa lifti ea hydraulic valve?

Ho nkela sebaka sa ho phahamisa valve ke ts'ebetso e rarahaneng e hlokang ho bula enjene. Ka hona, theko ea eona e batla e phahame 'me e fapana ho tloha mohlala o mong oa koloi ho ea ho o mong. Ka sebele, karolelano ho tloha ho 200 ho isa ho 500 euro nkela sebaka sa hydraulic distributor pushers.

Bala ka karolo feela ho tloha ho 20 ho isa ho 50 euro hydraulic valve lifter. Nahana ka ho atisa theko ea lifti ea haeteroliki ka palo ea lilifi tseo u li hlokang.

Ikutloe u lokolohile ho sheba Vroomly e leng karache e ntle ka ho fetisisa ea hydraulic valve lifter ka theko e tlase! Bapisa mechini e molemohali sebakeng sa heno ho ipapisitsoe le theko le maikutlo a bareki ba bang ho nka sebaka sa li-valve lifters tsa hau ka theko e ntle ka ho fetisisa.
