Yuav ua li cas los xyuas qhov zoo ntawm antifreeze, thiaj li tsis mus nyob rau hauv ib tug txaus ntshai teeb meem tom qab

Tsis muaj lub cav combustion sab hauv yuav kav ntev yam tsis muaj lub sijhawm txias. Feem ntau cov motors yog ua kua txias. Tab sis ua li cas koj thiaj paub tias cov tshuaj tiv thaiv kab mob hauv lub tsheb tau tas nws cov peev txheej thiab yuav tsum tau hloov? Cia peb sim ua kom tiav.

Yog vim li cas antifreeze yuav tsum tau hloov

Muaj ntau qhov chaw txav hauv lub cav uas kub thaum ua haujlwm. Thaum tshav kub kub yuav tsum tau muab tshem tawm ntawm lawv raws sij hawm. Rau qhov no, lub tsho hu ua yog muab nyob rau hauv niaj hnub motors. Qhov no yog ib qho system ntawm cov channel uas los ntawm kev tiv thaiv kab mob circulates, tshem tawm cov cua sov.

Kev lag luam niaj hnub muab cov tswv tsheb ntau yam tshuaj tiv thaiv kab mob.

Nyob rau tib lub sijhawm, nws cov khoom hloov pauv, thiab ntawm no yog vim li cas:

• txawv teb chaws impurities, av, qhov tsawg tshaj plaws hlau hais los ntawm lub tsho tuaj yeem nkag mus rau hauv cov tshuaj tiv thaiv kab mob, uas yuav ua rau muaj kev hloov pauv hauv cov tshuaj muaj pes tsawg leeg ntawm cov kua thiab ua kom tsis zoo hauv nws cov khoom cua txias;
• Thaum lub sij hawm ua hauj lwm, antifreeze tuaj yeem ua kom sov txog qhov kub thiab txias thiab maj mam evaporate. Yog tias koj tsis ntxiv nws cov khoom siv raws sijhawm, lub cev muaj zog yuav raug tso tseg yam tsis muaj cua txias.

Qhov tshwm sim ntawm untimely hloov ntawm antifreeze

Yog tias tus neeg tsav tsheb tsis nco qab hloov lub coolant, muaj ob txoj kev xaiv:

• lub cev muaj zog overheating. Lub cav pib ua tsis tiav, lub kiv puag ncig ntab, lub zog dips tshwm sim;
• lub cev muaj zog. Yog tias tus neeg tsav tsheb tsis quav ntsej cov cim qhia hauv kab lus dhau los, lub cav yuav jam. Qhov no yog nrog los ntawm kev puas tsuaj loj, kev tshem tawm uas yuav xav tau kev kho loj. Tab sis txawm nws yeej tsis pab tawm. Hauv ntau lub sijhawm, nws muaj txiaj ntsig ntau dua rau tus neeg tsav tsheb muag lub tsheb tsis zoo dua li kho nws.

Lub sijhawm hloov lub coolant

Lub sijhawm nruab nrab ntawm kev hloov tshuaj tiv thaiv kab mob yog nyob ntawm ob qho tib si ntawm lub hom ntawm lub tsheb thiab nws cov yam ntxwv kev, thiab ntawm lub tshuab txias nws tus kheej. Feem ntau, nws raug nquahu kom hloov cov kua dej txhua 3 xyoos. Qhov no yuav tiv thaiv corrosion hauv lub cev muaj zog. Tab sis cov tuam ntxhab ntawm cov tsheb nrov muaj lawv lub tswv yim ntawm qhov teeb meem no:

• ntawm Ford tsheb, antifreeze yog hloov txhua 10 xyoo los yog txhua txhua 240 txhiab kilometers;
• GM, Volkswagen, Renault thiab Mazda tsis xav tau lub txias txias tshiab rau lub neej ntawm lub tsheb;
• Mercedes yuav tsum muaj tshuaj tiv thaiv kab mob tshiab txhua 6 xyoo;
• BMWs hloov txhua 5 xyoos;
• Nyob rau hauv lub tsheb VAZ, cov kua hloov txhua txhua 75 txhiab kilometers.

Kev faib tawm ntawm antifreezes thiab cov chaw tsim khoom cov lus qhia

Niaj hnub no, coolants tau muab faib ua ob peb chav kawm, txhua tus muaj nws tus yam ntxwv:

• G11. Lub hauv paus ntawm chav kawm ntawm kev tiv thaiv kab mob no yog ethylene glycol. Lawv kuj muaj cov additives tshwj xeeb, tab sis nyob rau hauv tsawg heev. Yuav luag txhua lub tuam txhab tsim cov chav kawm ntawm cov tshuaj tiv thaiv kab mob no qhia hloov lawv txhua 2 xyoos. Qhov no tso cai rau koj los tiv thaiv lub cev muaj zog ntawm corrosion ntau li ntau tau;
  

  Arctic yog tus neeg sawv cev zoo tshaj plaws thiab nrov tshaj plaws ntawm G11 chav kawm.
• G12. Qhov no yog chav kawm ntawm coolants tsis muaj nitrites. Lawv kuj yog raws li ethylene glycol, tab sis qib ntawm nws cov purification yog ntau dua li ntawm G11. Cov neeg tsim khoom tawm tswv yim hloov cov kua dej txhua 3 xyoos thiab siv nws hauv cov motors uas muaj kev nce ntxiv. Yog li ntawd, G12 tshwj xeeb tshaj yog nrov nrog cov neeg tsav tsheb;
  

  Antifreeze G12 Sputnik muaj nyob rau hauv cov txee hauv txhua qhov chaw
• G12+. Lub hauv paus ntawm antifreeze yog polypropylene glycol nrog ib pob ntawm anti-corrosion additives. Nws yog non-toxic, decomposes sai thiab cais thaj chaw corroded zoo. Pom zoo siv nyob rau hauv motors nrog txhuas thiab cam khwb cia hlau qhov chaw. Hloov txhua 6 xyoo;
  

  Felix belongs rau G12+ antifreeze tsev neeg thiab muaj tus nqi pheej yig.
• G13. Antifreezes ntawm hybrid hom, ntawm lub hauv paus carboxylate-silicate. Pom zoo rau txhua hom cav. Lawv muaj cov complex ntawm anti-corrosion additives, yog li ntawd lawv yog cov kim tshaj plaws. Lawv hloov txhua 10 xyoo.

Hloov antifreeze nyob ntawm lub mileage ntawm lub tsheb

Txhua lub tuam txhab tsheb tswj lub sijhawm ntawm kev hloov cov dej txias. Tab sis cov neeg tsav tsheb siv tsheb sib txawv, yog li lawv npog qhov sib txawv. Yog li, cov chaw tsim khoom cov lus pom zoo ib txwm hloov kho rau lub tsheb mais:

• Cov tshuaj tiv thaiv hauv tsev thiab G11 tshuaj tiv thaiv kab mob hloov pauv txhua 30-35 txhiab mais;
• Cov kua dej ntawm cov chav kawm G12 thiab saum toj no hloov txhua 45-55 txhiab kilometers.

Cov nqi taw qhia qhov tseem ceeb tuaj yeem suav tias yog qhov tseem ceeb, vim nws yog tom qab lawv tias cov khoom siv tshuaj tua kab mob pib maj mam hloov.

Strip test ntawm lub cev muaj zog

Ntau tus tswv tsheb yuav tsheb ntawm lawv txhais tes. Lub cav nyob rau hauv xws li tsheb yog hnav tawm, feem ntau heev, uas tus muag khoom, raws li txoj cai, yog ntsiag to txog. Yog li ntawd, thawj qhov uas tus tswv tshiab yuav tsum ua yog kuaj xyuas qhov zoo ntawm cov tshuaj tiv thaiv kab mob hauv lub cav hnav. Txoj hauv kev yooj yim tshaj plaws los ua qhov no yog siv cov txheej txheem tshwj xeeb cov cim qhia, uas tuaj yeem yuav ntawm txhua lub khw muag khoom.

Ib txheej ntawm qhov taw qhia strips nrog lub nplai tuaj yeem yuav ntawm txhua lub khw muag khoom pib.

Tus neeg tsav tsheb qhib lub tank, txo cov sawb nyob ntawd, thiab tom qab ntawd muab nws cov xim sib piv nrog cov nplai tshwj xeeb uas tuaj nrog cov khoom siv. Txoj cai dav dav: qhov tsaus nti ntawm daim kab xev, qhov phem dua cov tshuaj tiv thaiv.

Visual kev ntsuam xyuas ntawm antifreeze

Qee zaum qhov tsis zoo ntawm lub coolant pom ntawm qhov muag liab qab. Antifreeze yuav plam nws cov xim qub thiab tig dawb. Qee lub sij hawm nws dhau los ua huab. Nws kuj tseem yuav siv cov xim brownish. Qhov no txhais tau hais tias nws muaj xeb ntau dhau, thiab corrosion ntawm qhov chaw tau pib hauv lub cav. Thaum kawg, ua npuas dej tuaj yeem tsim nyob rau hauv lub tank nthuav dav, thiab cov txheej tuab ntawm cov hlau tawv tawv ua rau hauv qab.

Yog hais tias ua npuas ncauj tshwm nyob rau hauv lub tank, lub antifreeze yuav tsum tau hloov urgently.

Qhov no qhia tau hais tias lub cav qhov chaw pib tawg thiab cov tshuaj tiv thaiv yuav tsum tau hloov sai sai, tom qab ntxuav lub cav.

Boil xeem

Yog tias muaj kev tsis ntseeg txog qhov zoo ntawm cov tshuaj tiv thaiv kab mob, nws tuaj yeem kuaj tau los ntawm boiling.

1. Ib me ntsis antifreeze yog poured rau hauv ib lub tais hlau thiab rhuab rau roj kom txog thaum nws boils.
   

   Koj tuaj yeem siv lub lauj kaub huv huv los sim tshuaj tiv thaiv los ntawm kev npau npau.
2. Kev saib xyuas yuav tsum tau them tsis yog rau lub boiling point, tab sis mus rau qhov tsis hnov ​​tsw ntawm cov kua. Yog tias muaj qhov tsis hnov ​​​​tsw ntawm ammonia nyob rau hauv cov huab cua, antifreeze yuav siv tsis tau.
3. Lub xub ntiag ntawm sediment nyob rau hauv qab ntawm cov tais diav kuj yog tswj. High-zoo antifreeze tsis muab nws. Cov khoom ntawm tooj liab sulphate feem ntau precipitate. Thaum lawv nkag mus rau hauv lub cav, lawv yuav nyob ntawm txhua qhov chaw rub tawm, uas yuav ua rau muaj kev kub ntxhov.

Khov kuaj

Lwm txoj hauv kev txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tiv thaiv kab mob.

1. Sau lub raj mis yas khoob nrog 100 ml ntawm coolant.
2. Cov huab cua ntawm lub raj mis yuav tsum tau tso tawm los ntawm me ntsis crushing nws thiab ceev lub cork (yog hais tias lub antifreeze hloov tawm mus rau falsified, nws yuav tsis tawg lub raj mis thaum nws khov).
3. Lub raj mis crumpled muab tso rau hauv lub freezer ntawm -35 ° C.
4. Tom qab 2 teev, lub raj mis raug tshem tawm. Yog hais tias lub sij hawm no lub antifreeze tsuas yog me ntsis crystallized los yog nyob twj ywm kua, nws yuav siv tau. Thiab yog tias muaj dej khov hauv lub raj mis, nws txhais tau tias lub hauv paus ntawm lub tshuab txias tsis yog ethylene glycol nrog cov khoom ntxiv, tab sis dej. Thiab nws yog tsis yooj yim sua kom sau qhov cuav no rau hauv lub cav.

Yog li, txhua tus neeg tsav tsheb tuaj yeem tshawb xyuas qhov zoo ntawm cov tshuaj tiv thaiv kab mob hauv lub cav, vim muaj ntau txoj hauv kev rau qhov no. Qhov loj tshaj plaws yog siv cov coolant ntawm chav kawm pom zoo los ntawm cov chaw tsim khoom. Thiab thaum siv nws, nco ntsoov ua kev hloov kho rau lub mileage ntawm lub tsheb.
