Lub cav tawg-hauv tom qab kho dua tshiab - cov lus qhia kws tshaj lij
Cov neeg tsav tsheb uas muaj kev paub paub tias tom qab yuav lub tsheb tshiab, nws yog ib qho tsim nyog yuav tsum tau nqa tawm qhov hu ua lub cav kub kub tawg rau qee lub sijhawm. Ntawd yog, thawj ob peb txhiab kis lus mev, ua raws li kev tsav tsheb zoo tshaj plaws, tsis txhob maj nrawm rau ntawm cov roj lossis nres, thiab tsis txhob cia lub cav tsis ua haujlwm thiab nyob rau lub sijhawm ntev. Ntawm peb lub vev xaib Vodi.su koj tuaj yeem nrhiav cov ntaub ntawv tiav ntawm yuav ua li cas thiaj ua tau lub cav kub kub tawg-hauv.
Txawm li cas los xij, dhau sijhawm, yuav luag txhua lub cav xav tau kev kho dua tshiab. Cov tsos mob uas "lub plawv" ntawm koj lub tsheb yuav tsum tau kuaj thiab kho yog raws li nram no:
- kev noj roj thiab cav roj maj mam nce;
- tus cwj pwm dub lossis grey pa luam yeeb tawm ntawm cov yeeb nkab tso;
- compression nyob rau hauv lub tog raj kheej txo;
- poob ntawm traction ntawm qis los yog siab ceev, lub cav nres thaum hloov ntawm iav mus rau iav.
Muaj ntau txoj hauv kev los tshem tawm tag nrho cov teeb meem no: hloov lub tog raj kheej thaiv gasket, siv ntau yam roj cav ntxiv, xws li XADO.
Txawm li cas los xij, cov no tsuas yog kev ntsuas ib ntus uas kho qhov xwm txheej ib ntus. Kev kho dua tshiab yog qhov kev daws teeb meem zoo tshaj plaws.
Lub tswv yim ntawm "qhov tseem ceeb" txhais tau hais tias kev kuaj mob tag nrho ntawm lub cav yog ua tiav thiab hloov tag nrho cov khoom hnav thiab ua tsis tiav.
Nov yog cov kauj ruam uas nws feem ntau muaj xws li:
- cav dismantling - nws raug tshem tawm los ntawm lub tsheb siv ib tug tshwj xeeb nqa, uas yav tas los disconnected tag nrho cov tshuab thiab cov khoom txuam nrog lub cav - clutch, gearbox, txias system;
- ntxuav - txhawm rau txheeb xyuas qhov tseeb ntawm qhov kev puas tsuaj thiab qhov tsis xws luag, nws yog ib qho tsim nyog yuav tsum tau ntxuav tag nrho cov chaw sab hauv los ntawm cov txheej txheem tiv thaiv roj, tshauv thiab soot, tsuas yog ntawm lub cav huv si tuaj yeem ntsuas txhua yam kom raug;
- Kev daws teeb meem - cov neeg saib xyuas ntsuas lub cav hnav, saib seb yuav tsum tau hloov dab tsi, ua cov npe ntawm cov khoom tsim nyog thiab kev ua haujlwm (sib tsoo, hloov cov nplhaib, tho txawv, txhim kho crankshaft lub ntsiab thiab txuas cov pas nrig, thiab lwm yam);
- kho nws tus kheej.
Nws yog tseeb hais tias tag nrho cov no yog ib qho kim heev thiab mob siab rau, uas tsuas yog cov kws tshwj xeeb zoo tuaj yeem siv tau. Tus nqi ntawm kev ua haujlwm nce ntau zaus thaum nws los txog rau cov tsheb txawv teb chaws. Yog vim li cas peb thiaj li tawm tswv yim tawm tsam kev yuav tsheb txawv teb chaws nrog ib mais ntawm ntau tshaj 500 txhiab kilometers. Nws yog qhov zoo dua los yuav ib lub tsev Lada Kalina lossis Priora twb - kev kho yuav pheej yig dua.
Cov txheej txheem ntawm kev khiav lub cav tom qab overhaul
Tom qab cov masters tiav kev kho, muab lub cav rov qab rau hauv qhov chaw, hloov tag nrho cov lim dej, txuas txhua yam thiab pib lub cav kom paub tseeb tias nws ua haujlwm zoo, lub tsheb tau npaj siv dua. Txawm li cas los xij, tam sim no koj tab tom ua haujlwm nrog lub tshuab tshiab, yog li koj yuav tsum tau khiav nws ib ntus kom tag nrho cov pistons, rings, thiab cov bearings dawb tau siv rau ib leeg.
Yuav ua li cas yog lub run-in tom qab lub overhaul?
Txhua yam nyob ntawm seb hom haujlwm twg tau ua tiav.
Lub run-in nws tus kheej implies ib co txheej xwm txheej xwm:
- kev siv hom maj mam thaum tsav tsheb;
- yaug lub cav ob peb zaug los ntawm kev sau thiab ntws cov roj cav (nws yog ib qho tsim nyog kom tsis txhob siv cov dej ntws los yog cov khoom siv ntxiv);
- hloov cov lim ntsiab.
Yog li, yog tias kev txhim kho kev ua haujlwm cuam tshuam rau lub tshuab xa hluav taws xob, hloov lub camshaft nws tus kheej, cov saw, cov li qub, nws txaus los khiav lub cav hauv thawj 500-1000 mais.
Yog tias, txawm li cas los xij, kev hloov pauv tag nrho, pistons nrog piston rings tau ua tiav, lub clutch tau hloov kho, lub ntsiab tshiab thiab txuas cov pas nrig bearings tau nruab rau ntawm lub crankshaft, thiab lwm yam, ces koj yuav tsum ua raws li kev sib tw. mus 3000km. Hom sparing implies qhov tsis tuaj yeem pib tam sim ntawd thiab nres, nws yog ib qho tsim nyog yuav tsum tsis txhob nrawm nrawm dua 50 km / h, lub crankshaft ceev yuav tsum tsis pub tshaj 2500. Tsis muaj qhov ntse jerks thiab overloads.
Qee tus yuav nug - vim li cas txhua qhov no xav tau yog tias kev ua haujlwm tau ua los ntawm cov tswv ntawm lawv cov khoom siv tes ua?
Peb teb:
- ua ntej; piston rings yuav tsum poob rau hauv qhov chaw nyob rau hauv lub piston grooves - nrog ib tug ntse pib, lub rings yuav yooj yim tawg thiab lub cav yuav jam;
- Secondly, thaum lub sij hawm lapping txheej txheem, hlau shavings inevitably daim ntawv, uas tsuas yog yuav tshem tawm los ntawm kev hloov lub cav roj;
- Thib peb, yog tias koj saib ntawm qhov chaw ntawm lub pistons nyob rau hauv lub tshuab raj, ces txawm tias tom qab kev sib tsoo zoo tshaj plaws koj yuav pom ntau cov tubercles taw qhia uas yuav tsum tau theem tawm thaum lub sijhawm tawg.
Nws tseem tsim nyog sau cia lwm qhov - txawm tias tom qab ua tiav kev saib xyuas ntawm kev tawg-hauv kev tswj hwm thawj 2-3 txhiab kis lus mev, kev sib tsoo tiav ntawm txhua qhov chaw tshwm sim tom qab 5-10 txhiab kilometers. Tsuas yog tom qab ntawd lub cav yuav tsum tau ua kom pom tag nrho nws cov peev xwm.
Qhia tswv yim
Yog li ntawd, ua ntej koj pib khiav lub cav tom qab ib tug loj overhaul, sim mus xyuas lub roj teeb nqi - nws yuav tsum tau them tag nrho, vim hais tias lub cav pib thawj zaug yog lub sij hawm tseem ceeb tshaj plaws, lub crankshaft yuav tig heev nruj thiab tag nrho cov roj teeb lub hwj chim yuav tsum. xav tau.
Lub ntsiab lus tseem ceeb thib ob yog txhawm rau txhim kho cov roj lim tshiab thiab sau cov roj cav zoo. Nws yog tsis yooj yim sua kom ntub cov lim hauv cov roj ua ntej kev teeb tsa, vim tias qhov ntsuas cua tuaj yeem tsim thiab lub cev muaj zog yuav muaj kev tshaib kev nqhis roj thaum lub sijhawm tseem ceeb tshaj plaws.
Thaum lub cav pib, cia nws nyob twj ywm kom txog thaum cov roj siab rov qab mus rau qhov qub - qhov no yuav tsum tsis pub dhau 3-4 vib nas this. Yog tias cov roj siab khaws cia nyob rau theem qis, lub cav yuav tsum tau muab tua tam sim ntawd, vim tias muaj qee qhov teeb meem ntawm cov khoom siv roj - lub ntsuas cua, lub twj tso kua mis tsis twj, thiab lwm yam. Yog tias lub cav tsis raug kaw rau lub sijhawm, txhua yam tuaj yeem ua tau los hloov kho tshiab yuav tsum tau ua.
Yog hais tias txhua yam zoo nrog lub siab, ces cia lub cav sov so rau qhov kub thiab txias. Raws li cov roj ua kom sov, nws ua kua ntau dua thiab lub siab yuav tsum txo qis rau qee qhov txiaj ntsig - txog 0,4-0,8 kg / cmXNUMX.
Lwm qhov teeb meem uas tuaj yeem tshwm sim thaum tawg-hauv tom qab kev kho dua tshiab yog cov dej xau ntawm kev siv tshuab. Qhov teeb meem no tseem yuav tsum tau daws sai sai, txwv tsis pub cov qib ntawm antifreeze los yog roj yuav poob, uas yog fraught nrog overheating ntawm lub cav.
Koj tuaj yeem pib lub cav ob peb zaug hauv txoj kev no, cia nws sov mus rau qhov xav tau qhov kub thiab txias, tig nws ntawm qhov tsis ua haujlwm me ntsis thiab tom qab ntawd tua nws. Yog hais tias nyob rau tib lub sij hawm tsis muaj suab nrov extraneous thiab khob tsis hnov, koj muaj peev xwm tawm ntawm lub chaw nres tsheb.
Ua raws li kev txwv ceev - thawj 2-3 txhiab tsis tsav nrawm dua 50 km / h. Tom qab 3 txhiab, koj tuaj yeem nrawm rau 80-90 km / h.
Qhov chaw ntawm lub cim ntawm tsib txhiab, koj tuaj yeem tso cov roj cav - koj yuav pom ntau npaum li cas txawv teb chaws hais nyob rau hauv nws. Siv tsuas yog cov roj pom zoo los ntawm cov chaw tsim khoom. Nws tseem tsim nyog xav txog tias yog tias lub geometry ntawm lub tog raj kheej hloov pauv - lawv tau dhuav, kho pistons nrog txoj kab uas hla loj dua - cov roj uas muaj viscosity siab dua yuav tsum tau ua kom muaj qhov xav tau qib compression.
Zoo, tom qab dhau 5-10 txhiab mais, koj tuaj yeem thauj lub cav tag nrho.
Hauv daim vis dis aus no, tus kws tshaj lij muab cov lus qhia txog kev ua haujlwm kom raug thiab lub cav tawg-hauv.
