Lub lubrication zoo yog tus yuam sij rau kev txhim khu kev qha thiab lub cav ua haujlwm ntev. Feem ntau, cov tswv tsheb tau khav txog tias lawv hloov cov roj hauv lawv lub tsheb ntau npaum li cas. Tab sis hnub no peb yuav tsis tham txog kev hloov pauv, tab sis hais txog topping. Yog hais tias nyob rau hauv thawj rooj plaub tsis muaj lus nug (tawm, ntim thiab tsav tsheb), ces nyob rau hauv lub thib ob rooj plaub, cov kev xav ntawm cov tsav tsheb txawv. Nws puas tuaj yeem sib xyaw cov khoom sib xyaw thiab cov khoom sib xyaw los ntawm cov tuam txhab sib txawv? Ib txhia hais tias ua tau. Lwm tus hais tias nws yog txwv tsis pub. Yog li, cia peb sim nkag siab qhov teeb meem no.

Yog vim li cas

Muaj ntau yam sib xyaw. Piv txwv li, tom qab taug kev mus rau lwm cheeb tsam, koj cov roj qib ntawm lub dipstick tau poob. Tshwj xeeb tshaj yog feem ntau qhov no tshwm sim ntawm turbocharged xyaw nrog ib mais ntawm ntau tshaj ob puas txhiab. Lawm, thiaj li hais tias lub cav tsiskev paub txog roj tshaib plab, koj yuav tsum rov pib nws qib sai li sai tau. Koj tsiv mus rau lub khw muag khoom ze tshaj plaws, tab sis tsis muaj roj ntawm cov txee uas koj tau ntim rau hauv koj lub tsheb. Puas yog nws muaj peev xwm sib tov cov khoom sib xyaw nrog cov khoom sib xyaw los ntawm cov tuam txhab sib txawv? Peb yuav tham txog qhov no me ntsis tom qab. Lub sijhawm no, xav txog lwm qhov laj thawj tseem ceeb uas koj yuav tsum tau ntxiv roj.

Qhov no yog qhov ua haujlwm tsis zoo ntawm pawg cylinder-piston. Yog li, kev noj cov kua roj lubricating yog cuam tshuam los ntawm qhov muaj cov qhab nia thiab lwm yam deformations ntawm lub tog raj kheej phab ntsa, nrog rau cov xwm txheej ntawm cov roj scraper rings. Cov tom kawg tuaj yeem pw tom qab ua haujlwm ntev. Tsis tas li ntawd, cov roj nkag mus rau hauv lub chamber vim lub ellipse ntawm lub tog raj kheej. Yog, tsis muaj leej twg txiav txim siab txog kev saib xyuas ntuj. Tab sis nws yuav tsum tsis txhob ntau tshaj 20 feem pua ntawm tag nrho cov ntim rau tag nrho lub sij hawm hloov (qhov no yog 8-10 txhiab kilometers). Yog tias koj yuav tsum tau ntxiv roj ntau zaus, qhov no yog lub sijhawm los xav txog kev ua haujlwm ntawm lub tog raj kheej-piston pawg.

Tsis tas li ntawd, yuav tsum tau ntim cov roj ntxiv rau lub tsheb vim qhov tsis zoo. Feem ntau cov tswv tsheb tsis nco qab hloov lub crankshaft roj foob (pem hauv ntej thiab nram qab). Ib feem yog pheej yig, tab sis txhawm rau hloov nws, koj yuav tsum tig ib nrab ntawm lub cav lub cav (tshwj xeeb tshaj yog tias nws yog cov roj foob rov qab). Nrhiav cov cim qhia txog kev xau ntawm lub cav thiab cov khoom txuas. Nws yog qhov ua tau tias koj yuav tsum tau sau cov roj kom meej vim yog lub foob tsis zoo.

Kev nkag siab txog kev sau ntawv

Yuav teb cov lus nug "nws puas tuaj yeem sib xyaw cov khoom sib xyaw thiab cov khoom sib xyaw los ntawm cov tuam txhab sib txawv", koj yuav tsum nkag siab txog cov khoom sib xyaw. Muaj peb hom lubricants. Tab sis tsis hais hom twg, cov roj muaj "puag" thiab cov khoom siv ntxiv uas muab tshwj xeeb rau tus kheej zoo. Qhov no siv rau hluavtaws, dej ntxhia thiab semi-synthetics. Nyob rau tib lub sijhawm, txhua lub chaw tsim khoom siv nws tus kheej thev naus laus zis thiab txoj hauv kev kom tau txais lub hauv paus ("base"), nrog rau nws cov txheej txheem ntxiv.

Yog li, txawm tias tib lub viscosity, cov khoom no yuav txawv ntawm ib leeg. Qhov no ua rau qee qhov teeb meem thaum sib xyaw cov roj sib txawv. Raws li kev ntsuam xyuas tau pom, rau qhov ntau dua, cov khoom sib txawv ntawm cov khoom siv ntxiv. Qhov no tsis tso cai rau kev sib xyaw synthetics los ntawm cov tuam txhab sib txawv. Qhov no puas tuaj yeem ua tiav nrog cov roj ntxhia? Cov lus teb yuav tsis zoo. Yog, cov dej ntxhia yog maj mam ua rau lub cav. Tab sis qhov no tsis txhais hais tias nws tuaj yeem sib xyaw nrog cov khoom lag luam los ntawm lwm cov tuam txhab.

Txhais tau

Yuav ua li cas yog tias koj ntxiv roj los ntawm lwm lub chaw tsim khoom rau lub cav? Tsis muaj leej twg yuav lav tias lub cev muaj zog yuav txais qhov "cocktail" zoo. Xwb, vim kev sib xyaw ntawm cov khoom sib txawv, slag yuav muab tso rau hauv lub cav.

Lub sijhawm ua haujlwm mus ntev, qhov no yuav ua rau coking ntawm lub nplhaib. Ib feem ntawm cov khoom yuav precipitate. Additives yuav tsis muab qhov kev ua tau zoo ib yam. Qhov sib xyaw ntawm cov roj zaj duab xis yuav raug cuam tshuam, uas tuaj yeem ua rau txhaws ntawm cov roj ua haujlwm. Tag nrho cov no ua rau ib tug loj overhaul ntawm lub cav. Nws puas tuaj yeem sib xyaw cov khoom sib xyaw thiabsynthetics los ntawm txawv manufacturers? Cov kws tshaj lij muab cov lus teb tsis zoo. Cov kev sim no tuaj yeem muaj qhov tshwm sim tsis zoo.

About viscosity

Raws li koj paub, cov roj muaj nws tus kheej SAE kev faib tawm thiab viscosity. Thaum xaiv cov khoom tshiab, yuav tsum tau them nyiaj tshwj xeeb rau viscosity. Qhov zoo ntawm kev pib lub cav nyob rau lub caij ntuj no thiab nws cov haujlwm hauv lub caij ntuj sov nyob ntawm qhov ntsuas no. Nws puas tuaj yeem sib xyaw cov khoom sib xyaw thiab cov khoom sib xyaw ntawm tib lub npe, tab sis nrog cov viscosities sib txawv? Koj tuaj yeem ua qhov no, tab sis nws tsis pom zoo. Cia peb ua piv txwv. Koj nyob hauv lwm lub nroog, thiab koj lub teeb roj teeb thaum muaj xwm ceev. Koj tshem tawm lub dipstick, thiab nws yog xyaum "qhuav". Tab sis tsis muaj roj nrog tib viscosity los ntawm ib lub chaw tsim khoom hauv khw.

Hloov 5w30 koj yuav 5w40. Qhov tshwm sim yuav ua li cas? Nws puas tuaj yeem sib xyaw 5w30 hluavtaws nrog 5w40? Thaum sib tov, koj yuav hloov cov yam ntxwv viscosity. Yog li, cov kua yuav tau txais qhov nruab nrab parameter (5w35). Dab tsi yuav hloov pauv yav tom ntej tom qab sib tov? Ntawm cov cim pom tseeb, nws tsim nyog sau cia qhov tsawg kawg nkaus lub cav pib kub. Tam sim no nws yuav yog -35 degrees Celsius. Tab sis tsis muaj leej twg tuaj yeem kwv yees seb cov tshuaj ntxiv yuav coj li cas hauv qhov no. Yog tias qhov no yog cov khoom lag luam los ntawm ib lub chaw tsim khoom, ces koj yuav tsis ua rau muaj kev phom sij loj. Tab sis thaum sib xyaw cov roj sib txawv, koj yuav tsum xav tias muaj teeb meem.

Nrog kev pheej hmoo tsawg

Yog li, yuav ua li cas yog tias qib poob qis thiab cov khw muag khoom tsis muaj roj ib yam? Muaj ob peb txoj cai kom paub:

• Sim xaiv cov zaub mov uasze li sai tau rau cov yam ntxwv ntawm koj cov roj. Yog li koj tshem tawm qhov txaus ntshai.
• Kuv puas tuaj yeem sib xyaw cov khoom sib xyaw thiab cov khoom sib xyaw los ntawm cov tuam ntxhab sib txawv? Tsis txhob yuav cov roj nplaum los ntawm lwm lub tuam txhab. Txhua lub tuam txhab siv nws tus kheej cov txheej txheem ntxiv uas tau ntxiv rau cov roj hauv paus. Vim li no, cov yam ntxwv ntawm zaj duab xis yuav txawv heev.
• Cia qhov sib txawv tsawg kawg nkaus hauv viscosity. Koj siv tsis tau 15w40 roj hauv lub cav uas yav tas los siv 0w20, txawm tias lawv muaj tib lub chaw tsim khoom.
• Tsis txhob hloov hom roj. Yog hais tias koj muaj hluavtaws sau rau hauv, nyob rau hauv tsis muaj cov ntaub ntawv tsis sib tov nrog ntxhia thiab txawm semi-synthetic (txawm hais tias lub viscosity yog tib yam). Qhov no yuav ua mob hnyav rau koj lub cav.

Yuav ua li cas thaum tuaj txog?

Yog li ntawd, koj rov qab los rau hauv koj lub nroog thiab muab lub tsheb tso rau hauv qhov chaw nres tsheb. Yuav ua li cas ntxiv? Cov kws tshaj lij pom zoo kom tso dej tas li "cocktail" thiab hloov nws mus rau cov roj tshiab, homogeneous. Ib kauj ruam nruab nrab yuav yog siv cov roj ntws tawm.

Qhov kev zam yog qhov sib ntxiv ntawm cov khoom sib txuas los ntawm ib lub chaw tsim khoom, tab sis nrog qhov sib txawv me me (raws li peb tau sau ua ntej, cov no yog 5w30 thiab 5w40). Yog tias cov roj ntim me me, nws tsis tas yuav ua kom tiav kev hloov pauv. Koj tuaj yeem caij nrog xws li "cocktail" thiab dhau mus. Peb yuav tham txog qhov nuance hauv qab no.

Ham tsis muaj ntim

Raws li koj paub, nws yog tsis yooj yim sua kom ntws tag nrho cov ntim ntawm cov roj los ntawm lub cav. Zoo li nws los yog tsis, tab sis 500-800 milliliters ntawm cov kua yuav tseem nyob hauv lub cev. Rautag nrho cov no yog dab tsi? Yog tias koj ntxiv roj me ntsis, koj tsis tas yuav ua lwm qhov txawv txav. Qhov no yog ib qho kev nyab xeeb kiag li uas yuav tsis ua mob rau koj lub cav. Tab sis nco ntsoov tias qhov no tsuas yog ua tau thaum sib xyaw cov khoom los ntawm tib lub chaw tsim khoom. Tsis tas li ntawd, qhov muaj pes tsawg leeg yuav tsum tsis txhob sib txawv ntau ntawm cov yam ntxwv viscosity.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws

Thaum koj mus taug kev ntev, nqa me me (tsawg kawg ib liter) qe roj rau hauv koj lub cev. Tej zaum koj yuav tsis xav tau. Tab sis yog tias tsim nyog, koj yuav txuag tau ntau lub sijhawm thiab kev siv dag zog los nrhiav qhov zoo viscosity thiab hom roj.

Ntxiv rau, ntawm cov chaw nres tsheb roj, tus nqi ntawm cov khoom noj khoom haus yog qhov kev txiav txim siab dua. Tsis tas li ntawd, ib lub lauj kaub me me nrog cov tshuaj tua kab mob thiab lwm cov kua dej ua haujlwm yuav tsis yog superfluous. Antifreeze, los ntawm txoj kev, kuj tsis tuaj yeem sib xyaw nrog cov chav sib txawv thiab cov chaw tsim khoom. Tab sis qhov no yog lub ntsiab lus rau lwm tsab xov xwm.

hloov mus rau lwm hom roj

Lub sijhawm dhau mus, cov tswv tsheb muaj lub siab xav hloov cov dej ntxhia mus rau cov khoom siv hluavtaws lossis lwm qhov. Tab sis qhov no yuav tsum tau ua kom raug, txij li qee cov roj tseem nyob hauv lub cav. Puas muaj peev xwm sib tov cov khoom xyaw nrog cov dej ntxhia? Tsis yog kiag li. Yog li ntawd, thaum hloov mus rau lwm hom kua, siv cov roj flushing. Tom qab cia lub cav khiav ntawm nws li 5-10 feeb, koj tsis tuaj yeem ntshai rau qhov tsis sib haum xeeb ntawm cov khoom siv ntxiv thiab "hauv paus".

Tom qab "flushing" ntws, koj tuaj yeem nchuav roj nrog kev ntseeg siablwm hom, tsis ntshai rau qhov tshwm sim. Tsis tas li ntawd tsis txhob hnov qab hloov cov roj lim. Nws kuj tseem khaws cov kua dej uas tsim nyog (thiab tsis muaj av tsawg dua tom qab kaum txhiab kilometers).

Zoo kawg

Yog li, peb pom tias nws puas tuaj yeem sib xyaw cov khoom sib xyaw thiab cov khoom sib xyaw ntawm tib lub tuam txhab sib txawv hauv lub cav tsheb. Raws li koj tau pom, topping nws tsis yog ib txwm muaj kev nyab xeeb. Nco ntsoov tias cov tuam txhab sib txawv siv cov kev sib txawv rau kev tsim cov roj cav thiab, tshwj xeeb, cov pob khoom ntxiv. Thiab lawv yuav coj li cas thaum sib xyaw nrog lwm cov kua, ib tus tsuas tuaj yeem kwv yees.
