Muaj tag nrho cov laj thawj vim li cas cov dej txias tuaj yeem npau. Tab sis feem ntau qhov teeb meem tuaj yeem kho ntawm nws tus kheej. Raws li kev xyaum qhia, feem ntau tus neeg tsav tsheb nws tus kheej yog rau txim. Tom qab tag nrho, lub tshuab cua txias yuav tsum tau ua haujlwm tsis tu ncua. Cia wb mus saib seb yog vim li cas cov tshuaj tua kab mob hauv lub tank nthuav dav, thiab yuav kho qhov teeb meem li cas.

cav txias system

Ua ntej tshaj plaws, Kuv xav kom nkag siab ntau ntxiv tias lub cav txias li cas. Lub system tag nrho tsis nyuaj, tab sis muaj qee qhov nuances hauv nws txoj haujlwm. Nws yuav tsum to taub tias sai li sai tau thaum koj pib lub tsheb cav, nws heats li intensely. Nws muaj cov kab tshwj xeeb los ntawm qhov uas cov coolant circulates nyob rau hauv siab thiab tshem tawm ib feem ntawm lub tshav kub. Lub ntsiab tseem ceeb ntawm cov cua txias system: radiators, twj tso kua mis, thermostat, expansion tank cap(air valve), nozzles, thiab lwm yam.

Qhov kub ntawm cov tshuaj tiv thaiv kab mob yog ntau dua li cov dej. Yog li ntawd nws yog siv nyob rau hauv niaj hnub tsheb. Yog tias peb nco qab txog qhov kev kawm ntawm physics, peb tuaj yeem txiav txim siab tias qhov nce hauv siab ua rau muaj qhov nce hauv qhov kub. Raws li, qhov siab dua, qhov siab dua qhov kub ntawm lub coolant yuav boil. Tab sis hnyav kev khiav hauj lwm hom (piv txwv li, sawv ntsug nyob rau hauv lub tsheb jams) inevitably ua rau ib tug tas li nce nyob rau hauv lub siab nyob rau hauv lub system. Thaum nws ncav cuag tus nqi, lub valve qhib, yog li tso pa ntau dhau rau hauv huab cua.

Hais txog kev saib xyuas tsis tu ncua

Raws li tau sau tseg nyob rau hauv qhov pib ntawm tsab xov xwm no, lub tshuab cua txias yuav tsum tau kuaj xyuas ib ntus rau cov dej xau, qhov xwm txheej ntawm cov tshuaj tiv thaiv, kev ua haujlwm ntawm lub twj tso kua mis thiab ntsuas kub. Yog tias qhov no tsis ua tiav, ces muaj peev xwm ua rau muaj kev puas tsuaj loj thiab overheating ntawm lub cav. Overhaul tsis yog ib qho pheej yig, yog li koj yuav tsum tsis txhob coj mus rau qhov no.

Lwm qhov tseem ceeb tshaj plaws yog kev pabcuam lub neej ntawm kev ua kom khov. Ntau yam nyob ntawm nws hom. Piv txwv li, nws yog ntshaw kom hloov G11 txhua ob peb xyoos, thiab G12 + tuaj yeem tiv taus yooj yim txog 5 xyoos. Nyob rau tib lub sijhawm, muaj cov chaw tsim khoom cov lus pom zoo rau hom coolant thiab qhov tsis tu ncua ntawm nws hloov. Yog li ntawd, yog tias koj pom tias antifreeze ib ntus boils nyob rau hauv lub expansion tank, ces qhov no tsis qhia ib tug neeg kho tshuab malfunction. Nws yog qhov ua tau tias nws tsuas poob qee qhov ntawm nws qhov kev ua tau zoo, uas yog vim li caslub boiling point tau poob lawm. Zoo, tam sim no cia peb mus ncaj qha rau cov teeb meem tseem ceeb thiab txoj hauv kev rau lawv tshem tawm.

Tsis txaus qib ntawm cov tshuaj tiv thaiv kab mob hauv lub tank nthuav dav

Thaum tsis muaj cov dej txias txaus hauv qhov system, qhov kub kub poob qis. Feem ntau, qhov teeb meem yog daws los ntawm kev tso nyiaj tsis tu ncua. Nws raug nquahu kom ua kom txias. Qhov no yog vim lub fact tias nyob rau hauv high kub cov kua expands. Yog li ntawd, yog hais tias koj sau nyob rau hauv lub expansion tank mus rau lub "yam tsawg kawg nkaus", thaum lub kaw lus txias, lub antifreeze yuav ua ntau tsawg.

Qhov tseeb, tsis muaj dab tsi nyuaj rau kev sau npe. Peb pom lub expansion tank thiab unscrew lub plug. Nws tuaj yeem yog cov yas zoo tib yam, uas yuav luag tsis muaj haujlwm, lossis airtight. Tom qab peb unscrewed nws, sau nyob rau hauv qhov yuav tsum tau tus nqi ntawm antifreeze. Nws yog ntshaw tias qib ntawm antifreeze nyob rau hauv lub expansion tank nyob nruab nrab ntawm qhov "siab tshaj" thiab "tsawg kawg". Raws li cov laj thawj vim tias qib poob, tsuas muaj qee qhov ntawm lawv. Nws zoo nkaus li tias thaum lub sij hawm kho ntawm lub system, antifreeze tsis tau ntxiv. Qhov kev xaiv thib ob yog qhov xau.

Thermostat tsis ua haujlwm

Yog tias koj pom tias cov tshuaj tiv thaiv tsis khov yog nyem tawm ntawm lub tank nthuav dav, ces qhov no yuav qhia tau tias muaj qhov kub hnyiab. Qhov tseeb yog tias nws ua haujlwm zoo li lub valve thiab muaj ob txoj haujlwm: kaw thiab qhib. Nyob rau hauv txoj hauj lwm kaw, kev ncig ntawm lub system yog nqa tawm nyob rau hauv ib lub voj voog me me. Nyob rau hauv ib lub voj voog loj, cov kua dhau los ntawm lub radiator, uascontributes rau nws ceev ceev txias. Yog hais tias lub cav tsheb txias, lub ntsuas cua sov valve kaw, uas ua rau kom ceev cua sov ntawm chav tsev fais fab. Thaum lub cav kub, qhov ntsuas kub qhib thiab cov dej txias ntws los ntawm lub tshuab hluav taws xob, qhov uas nws txias los ntawm cov cua ntws los lossis cov diffusers.

Peb yuav tau dab tsi yog tias lub ntsuas sov tau daig? Muaj ob txoj kev xaiv: lub antifreeze yog tas li boiling nyob rau hauv lub kub expansion tank. Qhov no yog vim tsis zoo coolant ncig. Nyob rau tib lub sijhawm, nws squeezes lub antifreeze tawm ntawm lub expansion tank, raws li nws tas li expands. Qhov no qhia tau hais tias lub valve yog daig nyob rau hauv qhov chaw kaw. Qhov kev xaiv thib ob yog lub tsheb yuav sov so rau lub sijhawm ntev heev. Rau txhua yam teeb meem nrog lub ntsuas sov, nws yuav tsum tau hloov, nws tsis kim dhau los txuag ntawm qhov tseem ceeb.
