Li-hydraulic lifters - ke eng
Enjene e futhumatsa nakong ea ts'ebetso, e lebisang ho atolosoeng ha tlhaho ha likarolo tsa tšepe. Baqapi ba ela hloko tšobotsi ena 'me kahoo ba siea likheo tse khethehileng tsa mocheso. Leha ho le joalo, tšobotsi e 'ngoe ea enjene ke ho roala butle-butle ha likarolo, ka ho latellana, likheo li atoloha' me re bona lintlha tse mpe tse kang ho fokotseha ha matla, ho fokotseha ha khatello, ho eketseha ha oli le mafura, le ho senyeha butle-butle ha likarolo tsa enjene.
Ntho ea bohlokoa ea enjene efe kapa efe ea peterole e tukang ka hare ke mokhoa oa ho aba khase.
Lintlha tsa eona tsa mantlha:
- camshaft e nang le lik'hamera tse entsoeng holim'a eona;
- li-valve tsa ho kenya le ho ntša metsi;
- li-valve lifters;
- camshaft pulley (e khanna shaft ka lebaka la lebanta la nako).
Re thathamisitse lintlha tsa sehlooho feela, empa bonneteng ho na le tse ling hape. Ntho ea bohlokoa ea nako ke ho etsa bonnete ba hore camshaft e potoloha ka mokhoa o ts'oanang le crankshaft, lik'hamera li hatella li-pusher (kapa matsoho a rocker), 'me le tsona li beha li-valve hore li tsamaee.
Ha nako e ntse e ea, ho na le likheo pakeng tsa libaka tse sebetsang tsa camshaft, li-pushers (kapa matsoho a rocker ka lienjineri tse bōpehileng joaloka V). E le ho ba lefella, ba ne ba sebelisa mokhoa o bonolo oa ho fetola ba sebelisa matšoao a khethehileng le li-wrenches. Ke ile ka tlameha ho fetola likheo ka tsela ea sebele ka lik'hilomithara tse 10-15 tse likete.
Ho fihlela joale, bothata bona bo se bo felile ka lebaka la ho qaptjoa le tšebeliso e atileng ea li-compensator tsa hydraulic.
Sesebelisoa le molao-motheo oa ts'ebetso ea compensator ea hydraulic
Ho na le mefuta e 'maloa ea mantlha ea li-hydraulic lifters tse etselitsoeng ho sebetsa ka mefuta e fapaneng ea nako (ka li-pusher, matsoho a rocker kapa ho kenya camshaft e tlase). Empa sesebelisoa ka boeona le molao-motheo oa ts'ebetso li tšoana hantle.
Lintlha tse ka sehloohong tsa compensator ea hydraulic:
- li-plunger pair (bolo, selemo, letsoho la plunger);
- mocha oa hore oli e kene ho compensator;
- mmele.
Compensator e kenngoa hloohong ea cylinder sebakeng se khethiloeng ka ho khetheha. Hape hoa khoneha ho li kenya mefuteng ea khale ea li-engines tseo ho tsona ho sa kang ha fanoa ka tsona.
Molao-motheo oa ts'ebetso o bonolo haholo. Khamera ea camshaft e na le sebopeho se sa tloaelehang. Ha a sa hatelle ho pusher, lekhalo pakeng tsa bona lea eketseha. Ka motsotso ona, mochine oa plunger o hatella valve ea plunger le oli e tsoang tsamaisong ea lubrication e kena ho compensator, karolo e sebetsang ea compensator e phahama hanyenyane, e beha pusher hore e tsamaee 'me lekhalo pakeng tsa cam le pusher le nyamela.
Ha camshaft e etsa phetoho 'me khamera e qala ho laela pusher, karolo e sebetsang ea compensator ea hydraulic e qala ho theoha ho fihlela mocha oa phepelo ea oli o koetsoe. Ka hona, khatello e ka hare ho compensator ea eketseha 'me e fetisetsoa ho stem valve ea enjene.
Kahoo, ka lebaka la bafani, ho ba sieo ha likheo ho tiisitsoe. Haeba u ntse u nahana hore sena sohle se etsahala ka lebelo le leholo - ho fihlela ho li-revolutions tse likete tse 6 ka motsotso - joale ka boithatelo ho na le ho hlolloa hore mokhoa o bonolo joalo o ka felisa bothata ba ho tlosoa ha mochine oa valve.
E ne e le ka lebaka la ho kenyelletsoa ha li-compensator tsa hydraulic hore ho khonehe ho finyella melemo e joalo ea lienjineri tse ncha ho feta tsa khale:
- ha ho hlokahale ho lula u lokisa li-valve clearances;
- ts'ebetso ea enjene e se e le bonolo ebile e khutsitse;
- palo ea meroalo e ts'oenyehileng ho li-valve le camshaft e fokotsehile.
Phoso e nyane ho tsoa ho ts'ebeliso ea li-hydraulic lifters ke ho kokota ho ka utluoa metsotsoana ea pele ea ho qala enjene e batang. Sena se bakoa ke taba ea hore khatello ea oli tsamaisong ha e lekane, 'me matšoao a khatello a lakatsehang a finyelloa ha oli e futhumetse mocheso o itseng' me e atoloha, e tlatsa likoti tse ka hare tsa li-compensator.
Mathata a mantlha a li-hydraulic lifters
Ke habohlokoa ho hlokomela hore para ea plunger ea compensator ke sesebelisoa se nepahetseng haholo. Lekhalo pakeng tsa sleeve le plunger ke li-microns tse seng kae. Ho feta moo, kanale ea phallo ea oli le eona e nyane haholo ka bophara. Ka hona, mekhoa ena e ameha haholo ka boleng ba oli. Ba qala ho kokota le ho hlōleha haeba oli ea boleng bo tlaase e tšeloa ka har'a enjene, kapa haeba e e-na le slag e ngata, litšila, lehlabathe, joalo-joalo.
Haeba ho na le mefokolo tsamaisong ea lubrication ea enjene, joale oli e ke ke ea khona ho kena ho li-compensators, 'me ho tloha ho sena ba tla chesa le ho hlōleha ka potlako.
Litsebi tsa portal ea likoloi vodi.su li lebisa tlhokomelo ea hau tabeng ea hore haeba li-compensator tsa hydraulic li kenngoa ka enjene, ha ho kgothaletswe ho e tlatsa ka oli e phahameng ea viscosity, e kang mineral 15W40.
Ha u kenya kapa u nkela li-compensator, etsa bonnete ba hore li tletse oli. Hangata li romelloa li se li tlatsitsoe. Haeba ho na le moea ka hare, ho ka etsahala hore ho be le tšubuhlellano ea moea 'me mochine o ke ke oa khona ho etsa mesebetsi ea oona.
Haeba koloi e qetile nako e telele e sa sebetse, oli e ka 'na ea tsoa ho tsoa ho li-compensator. Tabeng ena, o hloka ho li pompa: tlohela enjene e tsamaee ka lebelo le sa khaotseng, ebe ka lebelo le fapaneng, ebe ka ho se sebetse - oli e tla ea ho bafani.
Videong ena, setsebi se tla bua ka sesebelisoa le melao-motheo ea ts'ebetso ea li-hydraulic lifters.
