Yuav ua li cas xaiv lub coolant zoo?

Lub coolant nyob rau hauv lub radiator pab tswj kom zoo engine kub, uas yuav pab tau lub powertrain khiav zoo. Cov neeg tsav tsheb feem ntau xaiv qhov uas pheej yig dua txias, uas tuaj yeem ua rau ntau qhov tawg hauv lub tsheb. Cov kua dej tsawg dhau tuaj yeem ua rau lub cav overheat lossis ntes. Txhawm rau kom tsis txhob ua tsis tiav, nws yog qhov zoo tshaj los xaiv cov pov thawj thiab cov khoom ua kom zoo. Yog li dab tsi yog cov yam ntxwv ntawm lub coolant zoo? Nyeem thiab tshawb xyuas!

Vim li cas coolant tseem ceeb heev?

Lub tsheb mus txog qhov kub thiab txias thaum khiav ntawm lub cav ceev. Txias tswj qhov kub uas xav tau thiab tiv thaiv lub cuab yeej los ntawm overheating. Raws li qhov kub thiab txias, cov kua hloov pauv cua sov ntawm lub cav thiab lub tshuab hluav taws xob kom dissipate qhov kub thiab txias hauv qhov system dua. Lub coolant faib cov cua sov thiab yog li ua kom sov lub tsheb sab hauv.

Coolant - ntau lawm

Lub coolant ua li cas? Cov txheej txheem thev naus laus zis tau nthuav tawm hauv qab no:

• IAT (Inorganic Additive Technology) yog ib qho kev siv tshuab uas siv cov tshuaj inorganic additives. Cov additives no, uas yog, silicates thiab nitrates, tsim ib qho kev tiv thaiv los ntawm sab hauv thiab tshaj tag nrho cov nto. Cov kua dej no hnav sai sai, thiab yog tias tso rau hauv lub tshuab hluav taws xob ntev ntev, lawv tuaj yeem thaiv cov dej ntws. Coolant nrog IAT technology yuav ua hauj lwm nyob rau hauv lub cav nrog ib tug cam khwb cia hlau sab thiab ib tug txhuas lub tog raj kheej taub hau. Hom khoom no yog qhov zoo tshaj plaws hloov txhua ob xyoos;
• OAT (Organic Acid Technology) - nyob rau hauv cov ntaub ntawv ntawm lub tshuab no peb tab tom soj ntsuam nrog cov organic additives nyob rau hauv muaj pes tsawg leeg. Qhov no ua rau cov txheej txheem tiv thaiv thinner, txawm tias nws tsuas yog ua haujlwm zoo. Cov kua dej no muaj peev xwm hloov hluav taws xob ntau dua li IAT. OAT thev naus laus zis tsuas yog siv hauv cov tsheb tshiab. Tsis muaj cov hlau lead hauv cov radiators ntawm cov tsheb no. Txwv tsis pub, cov dej xau tuaj yeem tshwm sim. Cov dej txias no tuaj yeem kav ntev txog 5 xyoos;
• HOAT (Hybrid Organic Acid Technology) yog hybrid coolant uas muaj cov organic additives thiab silicate reagents. Qhov no yog qhov kev sib tw nthuav rau IAT tus neeg sawv cev. Cov qauv no yuav tso cai rau cov kua ua kom ntev dua thiab tiv thaiv corrosion.

Coolant - muaj pes tsawg leeg

Hom coolants kuj tuaj yeem paub qhov txawv ntawm lwm pawg. Cov muaj pes tsawg leeg ntawm cov coolant yuav txawv. Cov khoom muaj ethylene glycols los yog propylene glycols:

• Ethylene glycol muaj qhov kub thiab txias dua. Txias ntawm -11 ° C. Nws yog cov kua uas pheej yig dua los tsim thiab muaj qis viscosity. Ntawm qhov kub thiab txias nws crystallizes sai sai thiab absorbs cua sov tsawg. Qhov no tsis yog ib tug coolant nrog ib tug sensational muaj pes tsawg leeg, thiab nws yuav tsum tau ntxiv hais tias nws yog heev lom.;
• Propylene glycol txawv ntawm nws cov neeg sib tw hauv qhov uas nws tsis crystallize ntawm qhov kub thiab txias. Nws yog ntau yam tshuaj lom, uas yog vim li cas nws cov nqi siab dua.

Glycols ua haujlwm li cas?

Qhov kub ntawm ethylene glycol poob thaum nws yog diluted. Ib qho kev daws teeb meem zoo yog sib tov cov cawv no nrog dej. Vim li cas? Yog tias koj ntxiv dej ntxiv, txias Nws yuav tsis khov sai sai. Txhawm rau kom tau txais txiaj ntsig zoo ntawm glycol hauv koj cov dej, siv qhov sib piv ntawm 32% dej rau 68% glycol.

Yuav ua li cas xaiv lub coolant zoo?

Cov khoom tiav muaj nyob hauv khw txias los yog concentrates uas yuav tsum tau diluted nrog dej. Yog tias koj tsis ntxiv dej, cov concentrate nws tus kheej yuav pib khov ntawm -16°C. Yuav kom dilute cov kua condensed kom zoo, ua raws li cov chaw tsim khoom cov lus qhia. Cov coolant tiav lawm nyob rau hauv zoo tagnrho proportions, yog li tsis muaj dab tsi yuav tsum tau ntxiv. Nws qhov zoo dua yog nws qhov txias txias, uas ncav cuag -30°C. Yog tias koj xav paub seb hom chav tsev puas tseem ceeb, cov lus teb yog tias lub coolant rau lub cav diesel yuav zoo ib yam li lwm hom cav. 

Cov tub yees txias puas tuaj yeem sib xyaw?

Yog tias koj txiav txim siab muab cov kua sib txawv, koj yuav tsum ua tib zoo xyuas lawv cov muaj pes tsawg leeg. Lawv yuav tsum muaj cov additives zoo sib xws thiab tib lub hauv paus chiv keeb. Cov kua dej nrog cov khoom sib txawv tsis tuaj yeem sib xyaw, yog li tsis txhob sib tov, piv txwv li, cov kua dej nrog cov khoom siv tsis zoo thiab cov kua organic. Cov tub yees tuaj yeem ua rau muaj kev tiv thaiv tsawg dua. 

Hloov kua dej

Yuav ua li cas thaum koj tsis paub dab tsi cov kua tam sim no nyob rau hauv lub radiator thiab koj yuav tsum tau ntxiv ntxiv? Kev daws yog mus yuav ib tug universal. txias. Cov khoom no muaj cov khoom tiv thaiv corrosion uas tiv thaiv tsis tau tsuas yog txhuas, tab sis kuj tooj liab thiab hlau. Koj tuaj yeem yaug lub tshuab ua kom txias ua ntej ntxiv cov dej txias tshiab.

Dab tsi ntxiv koj yuav tsum paub txog coolant?

Nyob rau hauv cov xwm txheej uas yuav tsum tau ntxiv dej rau hauv qhov txias txias, nco ntsoov tias nws yuav tsum yog dej distilled. Cov dej tsis tu ncua txhawb kev tsim cov nplai thoob plaws hauv lub cev. Nws tseem ceeb heev uas cov kua tsis khov rau lub caij ntuj no. Lub boiling point ntawm lub coolant yuav tsum nyob nruab nrab ntawm 120-140 ° C. Cov khoom lag luam muaj cua txias yuav tsum tau diluted nrog dej demineralized, vim cov kua tuab nws tus kheej crystallizes ntawm -10 °C.

Cov xim ntawm lub coolant puas tseem ceeb?

Feem ntau coolant xim liab, liab, xiav thiab ntsuab. Qhov no feem ntau yog kev tsim cov tshuab tsim khoom, tab sis tsis yog txoj cai. IAT feem ntau yog tsaus ntsuab lossis xiav xim. OAT kua dej feem ntau yog liab, liab, ntshav, lossis tsis muaj xim.

Vim li cas thiaj muaj ntau yam xim thaum nws los txog rau lub coolant? Cov xim ntawm cov kua yog teev los ntawm cov tuam ntxhab rau kev nyab xeeb.. Tag nrho cov no kom tsis txhob muaj kev sib tsoo, nrog rau kom yooj yim nrhiav cov xau hauv qhov system.

Lub coolant yuav tsum tau hloov ntau npaum li cas?

Tsis txhob hnov ​​qab hloov lub coolant. Tsis ua li ntawd yuav ua rau lub tsheb puas tsuaj loj. noj txias tus tsav tsheb yuav tsuas tsis pom. Tsis muaj cov coolant zoo txhais tau hais tias lub tshuab cua txias tsis ua haujlwm zoo. Qhov no tuaj yeem ua rau lub cav ua haujlwm tsis zoo thiab muaj feem ntau ntawm corrosion. Cov neeg tsim khoom feem ntau pom zoo kom hloov cov kua dej txhua 5 xyoos lossis txhua 200-250 km.

Cov cai tseem ceeb thaum hloov cov kua dej

Thaum hloov cov kua dej koj yuav tsum:

• siv coolant tsim rau qhov system no;
•  ib txwm xaiv cov khoom muaj npe. Ntau dua li cov khoom siv hloov pauv, cov kua siv cov thev naus laus zis tshiab thiab lav zoo;
• yaug cov cua txias ua ntej txhua qhov hloov;
• tsis txhob sib tov kua. Thaum lub tsheb tsis ua haujlwm vim yog cov dej txias sib xyaw, tsis muaj cov chaw tsim khoom lag luam muaj lub luag haujlwm rau kev puas tsuaj. Yog tias koj xav tau ntxiv cov kua, xaiv lub npe hom, cov khoom kim dua. Thaum cov kua dej tawm, hloov nws nrog ib qho tshiab.

Coolant - dab tsi yog qhov tshwm sim ntawm kev xaiv tsis raug?

Qhov tshwm sim ntawm cov kua dej qub lossis cov dej tsis zoo tuaj yeem sib txawv. Feem ntau qhov no yog:

• corrosion ntawm tag nrho cov system;
• tsis muaj kev tiv thaiv.

Laus coolant

Qhov feem ntau ua rau corrosion nyob rau hauv lub txias system yog qub coolant uas tau tso rau ntev dhau lawm. Corrosion txhais tau tias nws tau tso tseg. Thaum lub sijhawm ua haujlwm, cov kua dej qub yuav pib ua npuas dej. Nyob rau hauv lub qub txias tsawg glycol, uas yuav ua rau lub cav overheat. Kuj ua raws li:

• kais dej los yog distilled dej;
• Cov kua dej tsis haum rau cov khoom siv hluav taws xob.

Kais los yog distilled dej

Qhov no tuaj yeem ua rau overheating ntawm lub cav thiab, vim li ntawd, mus rau jamming. Kev siv nws tuaj yeem ua rau lub tshuab cua sov thiab cov cua txias ua rau txhaws nrog nplai.

Xaiv cov kua dej tsis raug rau cov khoom siv hluav taws xob

Yog tias koj xaiv cov khoom tsis raug, tag nrho cov cua txias yuav dhau los ua corroded. Kev xeb kuj tuaj yeem cuam tshuam qee qhov hlau.

Thaum xaiv lub coolant, xyuam xim rau cov muaj pes tsawg leeg thiab additives. Xyuas kom tseeb tias hom khoom yog nyob rau hauv qhov txias txias. Ces koj yuav paub tseeb tias tsis muaj dab tsi yuav puas. Automotive coolant ua kom txhua lub cav khiav ntawm qis thiab siab ceev. Yog li ntawd, nco ntsoov hloov nws tsis tu ncua thiab sim kom tsis txhob pheej yig hloov pauv thiab sib tov tshuaj.
