Yuav ua li cas koj sim tshuab txias?

Testing engine coolant is essential for preventing overheating, corrosion, and freezing damage. Here's a comprehensive guide:

Cov Ntsiab Lus Los Kuaj

Khov / Boil point:Concentration ntawm cov tshuaj antifroued vs . dej .

Ph theem:Acidity / Alkalinity (qhia txog kev xeb corrosion) .

Kev mob / paug:Av, xeb, roj, lossis tso roj dim .

Cov cuab yeej koj koj yuav xav tau

Lub caij txias txias(feem ntau yog) lossisDab kaum(Tsoos ntab hom)

Coolant Ph / Kuaj Kab Mob(Ntau lub ncoo cov kab ntawv ntsuas PH & cov qib ntxiv)

Kev muag khaub ncaws huv / ntawv so tes

Kev Ruaj Ntseg Tsom & Nitrile Hnab Looj

Funnel (Yeem)

Tus tswv tsev phau ntawv (los qhia hom hom coolant)

Kauj ruam-rau-kauj ruam xeem

Kev Nyab Xeeb Ua Ntej:

Cav yuav tsum txias!Kub txias yog nias thiab tuaj yeem ua rau hnyav kub ntxhov .

Hnavhnab looj testhiabKev Nyab Xeeb Kev Nyab Xeeb- COOLANT (Tshwj xeeb tshaj yog Ethylene glycol) yog lom .

Ua haujlwm hauv thaj chaw muaj cua zoo .

Nrhiav cov khoom lag luam txias txias:

Nrhiav cov txhais lus yas ntxiv rau / nthuav dav tank (feem ntau yog lo cim) .}}}}.

Tsis txhob qhib Radiator Cap ntawm lub cav kub!Tsuas yog siv cov dej khov yog tias ua tau . yog kojyuav tsumqhib lub radiator, xyuas kom lub cav yog pob zeb txias .

Kev Ntsuam Xyuas Pom:

Xim:Nws puas yog qhov kev cia siab xim (e {{{{0} g {}}}}, ntsuab, txiv kab ntxwv, xim liab, xiav)? Tseem ceeb discoloration (xim av, av nkos, xeb) qhia tau kev sib kis lossis tsis pom zoo.

Clarity:Yuav tsum pom meej thiab ci {{0} {}} pos huab, murky, lossis oily txias yog tsis zoo .

Khib nyiab:Saib rau cov khoom ntab, sludge, lossis roj sheen rau saum .

Theem:Puas yog nws nruab nrab ntawm "min" thiab "max" cim? Tsawg theem xav tau kev tshawb nrhiav .

Kuaj kom khov / boil taw tes (concentration):

Siv tus (zoo tshaj):

Nqa lub pas dej cuav kom zoo zoo .

Siv pipette (feem ntau suav nrog) los kos coolant .

Tso ob peb tee ntawm qhov chaw refractometer tus prism .

Kaw lub hau phaj .

Tuav ntawm lub teeb, saib los ntawm lub qhov muag daj .

Nyeem cov nplai uas cov kab xiav / dawb ntsib (feem ntau cim hauv Degree F / Degree freeze point thiab% glycol) {{0.

Kev Siv Ib Lub Hydrometer:

Kos txias rau hauv lub raj hydrometer ntawm lub teeb nyem .

Xyuas kom muaj kua txaus kom ntab lub ntsuas (ntab lossis pob) .

Nyeem cov ntsiab lus kom khov raws qhov twg cov ntab so lossis muaj pes tsawg pob ntab .

Txhais:Piv cov kev nyeem ntawv rau daim ntawv qhia tau luam tawm ntawm lub cuab tam lossis dej txias}}} Degree) Tsis muaj zog (ntxiv txias (ntxiv distilled dej) .

Kev Ntsuas Ph & Mob (Siv cov ntawv xeem):

Dip Ntau qhov kev kuaj ntsuas hauv ntau dua rau hauv lub caij txias rau lub sijhawm ntawm lub taub hau (feem ntau ~ 1 thib ob) {2} {2}

Co tawm cov kua dej dhau heev .

Tos lub sijhawm teev tseg (feem ntau 15-45} vib nas this) .

Piv cov xim ntaub ntawv rau daim duab qhia ntawm lub raj mis:

PH ncoo:Yuav tsum nyob hauv cov alkaline ntau (feem ntau 7.5 - 10.5, zoo heev8.0 - 9.5 rau feem ntau txias).Tsawg PH (<7) = ACIDIC = Corrosion is happening!

Ntxiv / cia alkalinity (ra) ncoo:Qhia tias seem uas tsis muaj neeg inhibitors . xim yuav tsum yog nyob rau hauv "tsim nyog"} "txhais tau tias depleted.

Lwm cov ntaub qhwv:Qee qhov kev ntsuam xyuas ib zaug rau cov paug lossis hom kev sib ntxiv .

Kuaj xyuas kom muaj kev paug loj (qib siab):

Roj:Milky xim av sludge nyob rau hauv coolant los yog ntawm dipstick / roj cap . saib tsis tau gasket (roj taub qab zib).

Tso kua roj:Siv "block Serter" kua (hloov xim) kuaj pom kev ua pa hluav taws xob hauv lub taub hau txias, qhia tau lub taub hau gasket dej xau.

Xeb:Ntau xim av / liab hais .

Cov kev txiav txim tseem ceeb

Coolant Hom Teeb Meem:Siv hom uas tau teev tseg hauv koj tus tswv phau ntawv (OAT, Hoat, Hoat, Hoat, Hoat, Hoat, hom kev sib xyaw tuaj yeem ua rau muaj kev tiv thaiv lossis poob ntawm.

Hnub nyoog:Txias degrades hla lub sijhawm . Feem ntau cov tuam ntxhab pom zoo hloov txhua}}} mais (.

Tsis txhob cia li tawm mus:Pheej ntxiv cov dej ua rau cov dej ua kom txias txias .}}}} ntxiv txoj kev xav tau zoo ua rau nws muaj zog heev. qhov chaw nyobqho tseem ceebrau qib qis .

Siv dej distilled:Ib txwm sib tov nrog dej distilled kom tiv thaiv cov ntxhia ntxia .

Pov tseg:Siv txias txias yog cov tshuaj lom neeg heev . Noj nws mus rau lub khw pib, chaw ua haujlwm rov ua dua tshiab, lossis cov khoom pov tseg kev phom sij.Tsis txhob muab nws tso rau hauv dej ntws lossis hauv av .

Thaum tsis paub txog, lossis yog cov teeb meem uas muaj teeb meem tseem ceeb (tsis tshua muaj phem), ua tiav cov kev kawm txias dua tshiab yog qhov zoo tshaj plaws ntawm kev ua .Yog tias koj xav tias muaj dej ntws sab hauv (roj lossis kev sib zog), sab laj tus kws kho tshuab mechanic.
