Cov yam ntxwv ntawm Dextron 2 thiab 3 - dab tsi yog qhov txawv
Txheem
Cov dej sib txawv Dexron 2 thiab 3, uas yog siv nyob rau hauv lub hwj chim steering thiab tsis siv neeg kis tau tus mob, yog nyob rau hauv cov nqe lus ntawm lawv fluidity, hom roj hauv paus, raws li zoo raws li kub yam ntxwv. Hauv cov ntsiab lus dav dav, peb tuaj yeem hais tias Dextron 2 yog cov khoom qub tshaj tawm los ntawm General Motors, thiab raws li, Dextron 3 yog tshiab dua. Txawm li cas los xij, koj tsis tuaj yeem hloov cov kua dej qub nrog ib qho tshiab. Qhov no tsuas yog ua tau los ntawm kev soj ntsuam cov chaw tsim khoom, nrog rau cov yam ntxwv ntawm cov kua dej lawv tus kheej.
Generations ntawm Dexron kua thiab lawv cov yam ntxwv
txhawm rau txheeb xyuas qhov sib txawv ntawm Dexron II thiab Dexron III yog dab tsi, nrog rau qhov sib txawv ntawm ib qho thiab lwm yam dej sib kis, koj yuav tsum tau nyob luv luv ntawm keeb kwm ntawm lawv cov kev tsim, nrog rau cov yam ntxwv uas muaj. hloov ntawm tiam mus rau tiam.
Dexron II specifications
Cov kua dej sib kis no tau tso tawm thawj zaug los ntawm General Motors hauv xyoo 1973. Nws thawj tiam hu ua Dexron 2 los yog Dexron II C. Nws yog raws li cov roj ntxhia los ntawm pawg thib ob raws li API kev faib tawm - American Petroleum Institute. Raws li cov qauv no, cov roj hauv paus ntawm pawg thib ob tau txais los ntawm kev siv hydrocracking. Tsis tas li ntawd, lawv muaj tsawg kawg yog 90% saturated hydrocarbons, tsawg dua 0,03% sulfur, thiab tseem muaj qhov ntsuas viscosity ntawm 80 txog 120.
Thawj cov tshuaj ntxiv uas tau pib ntxiv rau cov kua dej sib kis yog cov tshuaj tiv thaiv corrosion. Raws li daim ntawv tso cai thiab kev xaiv (Dexron IIC), qhov sib xyaw ntawm pob yog qhia pib nrog tsab ntawv C, piv txwv li, C-20109. Cov chaw tsim khoom tau qhia tias yuav tsum tau hloov cov kua dej mus rau ib qho tshiab txhua 80 txhiab kilometers. Txawm li cas los xij, hauv kev xyaum, nws tau muab tawm tias corrosion tshwm sim sai dua, yog li General Motors tau tsim cov tiam tom ntej ntawm nws cov khoom.
Yog li ntawd, nyob rau hauv 1975, cov kua kis tau tus mob tshwm sim Dexron II (D). Nws tau ua rau tib lub hauv paus ntxhia roj ntawm pawg thib ob, txawm li cas los xij, nrog kev txhim kho ntawm cov tshuaj tiv thaiv corrosion ntxiv, uas yog, tiv thaiv corrosion ntawm cov pob qij txha hauv cov roj txias ntawm kev sib kis tsis siv neeg. Xws li cov kua muaj qhov ua haujlwm siab tsawg kawg nkaus tso cai ua haujlwm kub - tsuas yog -15 ° C. Tab sis txij li thaum viscosity tseem nyob rau theem siab txaus, vim yog kev txhim kho ntawm cov kab ke sib kis, qhov no tau pib ua rau muaj kev vibrations thaum lub sijhawm txav ntawm qee cov qauv ntawm cov tsheb tshiab.
Pib xyoo 1988, automakers pib hloov pauv tsis siv neeg kis los ntawm hydraulic tswj system mus rau ib qho hluav taws xob. Raws li, lawv xav tau cov kua sib txawv tsis siv neeg kis nrog cov viscosity tsawg, muab tus nqi ntau dua ntawm kev quab yuam hloov (xws li teb) vim qhov dej zoo dua.
Hauv 1990 tau tso tawm Dexron II (E) (qhov kev qhia tshwj xeeb tau hloov kho thaum Lub Yim Hli 1992, qhov rov tso tawm tau pib hauv 1993). Nws muaj tib lub hauv paus - pawg API thib ob. Txawm li cas los xij, vim yog siv cov pob khoom ntxiv niaj hnub no, cov roj iav tam sim no suav tias yog hluavtaws! Qhov kub siab tshaj plaws rau cov kua no tau raug txo mus rau -30 ° C. Kev txhim kho kev ua tau zoo tau dhau los ua tus yuam sij rau kev sib kis tsis siv neeg hloov pauv thiab ua kom muaj kev pabcuam lub neej. Daim ntawv tso cai npe pib nrog tsab ntawv E, xws li E-20001.

Qhov sib txawv ntawm Dexron 2 thiab Dexron 3 rau kev sib kis tsis siv neeg
Ua ntej sau los yog sib tov sib txawv ntawm cov kua kis tau tus mob, koj yuav tsum paub seb cov kua dej dab tsi lub automaker pom zoo siv. Feem ntau cov ntaub ntawv no yog nyob rau hauv cov ntaub ntawv technical (phau ntawv), rau qee lub tsheb (piv txwv li, Toyota) nws yuav raug qhia rau ntawm lub gearbox dipstick.
Qhov zoo tshaj plaws, tsuas yog cov roj nplua nyeem ntawm cov chav kawm uas tau teev tseg yuav tsum tau muab tso rau hauv qhov tsis siv neeg kis tau tus mob, txawm hais tias los ntawm chav kawm mus rau chav kawm ntawm cov kua muaj kev txhim kho cov yam ntxwv uas cuam tshuam rau nws lub sijhawm. Tsis tas li ntawd, koj yuav tsum tsis txhob sib tov, soj ntsuam qhov hloov zaus (yog tias kev hloov pauv tau muab rau txhua qhov, vim muaj ntau lub tshuab tsis siv neeg niaj hnub no tau tsim los ua haujlwm nrog ib qho kua rau tag nrho lub sijhawm ntawm lawv txoj haujlwm, tsuas yog nrog cov kua ntxiv thaum nws hlawv tawm) .
ntxiv nws yuav tsum nco ntsoov tias kev sib xyaw cov kua dej raws li cov ntxhia thiab cov khoom siv hluavtaws raug tso cai nrog kev txwv! Yog li, nyob rau hauv ib lub thawv tsis siv neeg, lawv tuaj yeem sib xyaw tsuas yog tias lawv muaj tib hom additives. Hauv kev xyaum, qhov no txhais tau tias koj tuaj yeem sib tov, piv txwv li, Dexron II D thiab Dexron III tsuas yog lawv tau tsim los ntawm tib lub chaw tsim khoom. Txwv tsis pub, cov tshuaj tiv thaiv tuaj yeem tshwm sim hauv kev sib kis tsis siv neeg nrog nag lossis daus, uas yuav txhaws cov kab nyias nyias ntawm lub torque converter, uas tuaj yeem ua rau nws tawg.
Qhov txawv ntawm Dexron II D thiab Dexron II E yog thermal viscosity. Txij li thaum ua haujlwm kub ntawm thawj cov kua yog mus txog -15 ° C, thiab qhov thib ob yog qis dua, mus txog -30 ° C. Tsis tas li ntawd, hluavtaws Dexron II E yog qhov ruaj khov dua thiab muaj kev ua haujlwm ruaj khov dua thoob plaws hauv nws lub neej voj voog. Ntawd yog, hloov Dexron II D nrog Dexron II E tau tso cai, txawm li cas los xij, ntawm qhov xwm txheej uas lub tshuab yuav siv rau hauv qhov tseem ceeb frosts. Yog tias huab cua kub tsis poob qis dua -15 ° C, ces muaj kev pheej hmoo tias thaum kub kub ntau dua cov kua Dexron II E yuav pib nkag los ntawm cov gaskets (cov ntsaws ruaj ruaj) ntawm kev sib kis tsis siv neeg, thiab tsuas yog ntws tawm ntawm nws, tsis hais qhov hnav ntawm qhov chaw.
Thaum hloov los yog sib tov cov kua dextron, nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account qhov yuav tsum tau ntawm cov chaw tsim tshuaj paus tsis siv neeg kis tau tus mob, txawm tias nws tso cai rau txo kev sib txhuam thaum hloov cov kua ATF, vim tias qhov no tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm chav tsev xwb, tab sis kuj yog nws cov khoom siv. durability, thiab muab tus nqi siab ntawm kev sib kis, qhov no yog qhov sib cav tseem ceeb!
Tswv yim Kev hloov Dexron II E nrog Dexron II D yog qhov tsis txaus ntseeg tsis txaus ntseeg, txij li thawj muaj pes tsawg leeg yog hluavtaws thiab nrog qis viscosity, thiab qhov thib ob yog ntxhia-raws li thiab nrog viscosity ntau dua. Tsis tas li ntawd, Dexron II E yog cov kev hloov kho zoo dua (cov tshuaj ntxiv). Yog li, Dexron II E yuav tsum tsuas yog siv nyob rau hauv cov cheeb tsam uas muaj huab cua hnyav heev, tshwj xeeb tshaj yog xav tias Dexron II E yog kim dua li nws cov thawj coj (vim yog cov khoom siv hluav taws xob kim dua).
Raws li rau Dexron II, nws hloov los ntawm Dexron III nyob ntawm tiam. Yog li, thawj Dexron III F txawv me ntsis ntawm Dexron II E, yog li Hloov qhov thib ob "Dextron" nrog qhov thib peb yog qhov zoo heev, tab sis tsis hloov pauv, rau qhov zoo sib xws.
Nrog rau Dexron III G thiab Dexron III H, lawv kuj muaj viscosity ntau dua thiab cov txheej txheem hloov kho uas txo kev sib txhuam. Qhov no txhais tau hais tias txoj kev xav lawv tuaj yeem siv tsis tau Dexron II, tab sis nrog qee qhov kev txwv. xws li, yog tias cov khoom siv (tsis siv neeg kis tau tus mob) tsis tso cai rau txo qis hauv kev sib txhuam ntawm cov kua dej ATF, hloov dextron 2 nrog dextron 3, raws li ntau "zoo meej" muaj pes tsawg leeg, tuaj yeem ua rau cov txiaj ntsig tsis zoo hauv qab no:
- Nce iav hloov ceev. Tab sis nws yog precisely no kom zoo dua uas distinguishes ib tug tsis siv neeg kis tau tus mob nrog hluav taws xob tswj los ntawm ib tug tsis siv neeg kis tau tus mob nrog hydraulic tswj.
- Jerks thaum hloov cov iav. Nyob rau hauv cov ntaub ntawv no, cov kev sib txhuam discs nyob rau hauv lub automatic gearbox yuav raug kev txom nyem, uas yog, hnav tawm ntau.
- Tej zaum yuav muaj teeb meem nrog kev tswj hluav taws xob ntawm qhov tsis siv neeg kis. Yog tias qhov hloov pauv yuav siv sijhawm ntev dua li qhov xav tau, tom qab ntawd cov tshuab hluav taws xob tswj hluav taws xob tuaj yeem xa cov ntaub ntawv hais txog qhov yuam kev mus rau chav tswj hluav taws xob.
Dexron III kis tau tus mob nyob rau hauv qhov tseeb, nws yuav tsum tau siv nyob rau hauv sab qaum teb cheeb tsam, qhov twg qhov kub ntawm kev siv lub tsheb nrog tsis siv neeg kis tau tus mob mus txog -40 ° C. Yog hais tias xws li cov kua yuav tsum tau siv nyob rau hauv cov cheeb tsam yav qab teb, ces cov ntaub ntawv ntawm kam rau ua yuav tsum tau nyeem nyias nyob rau hauv cov ntaub ntawv rau lub tsheb, vim qhov no tsuas tuaj yeem ua mob rau qhov tsis siv neeg kis tau tus mob.
Yog li, cov lus nug nrov ntawm qhov twg yog qhov zoo dua - Dexron 2 lossis Dexron 3 yog nyob rau hauv nws tus kheej tsis raug, vim hais tias qhov sib txawv ntawm lawv muaj tsis tsuas yog nyob rau hauv cov nqe lus ntawm tiam, tab sis kuj nyob rau hauv cov nqe lus ntawm destinations. Yog li ntawd, cov lus teb rau nws nyob ntawm, thawj zaug, ntawm cov roj pom zoo rau kev sib kis tsis siv neeg, thiab thib ob, ntawm kev ua haujlwm ntawm lub tsheb. Yog li ntawd, koj tsis tuaj yeem ua qhov muag tsis pom ntawm "Dextron 3" es tsis txhob "Dextron 2" thiab xav tias qhov kev sib kis tsis siv neeg no tsuas yog zoo dua. Ua ntej tshaj plaws, koj yuav tsum ua raws li cov lus pom zoo ntawm automaker!
Dextron 2 thiab 3 qhov sib txawv rau kev tswj fais fab
Raws li kev hloov pauv ntawm lub hwj chim steering kua (GUR), qhov laj thawj zoo sib xws yog siv tau ntawm no. Txawm li cas los xij, muaj ib qho subtlety ntawm no, uas yog qhov viscosity ntawm cov kua dej tsis yog qhov tseem ceeb heev rau lub hwj chim steering system, vim hais tias qhov kub ntawm lub hwj chim steering twj tso kua mis tsis nce siab tshaj 80 degrees Celsius. Yog li, lub tank lossis lub hau yuav muaj cov ntawv sau "Dexron II lossis Dexron III". Qhov no yog vim lub fact tias tsis muaj nyias raws ntawm lub torque converter nyob rau hauv lub hwj chim steering, thiab lub zog kis los ntawm cov kua yog ntau tsawg.
Yog li, los ntawm thiab loj, nws raug tso cai los hloov Dextron 3 es tsis txhob ntawm Dextron 2 nyob rau hauv lub hydraulic booster, tab sis tsis nyob rau hauv txhua rooj plaub. Qhov tseem ceeb tshaj plaws yog tias cov kua yuav tsum tsim nyog raws li cov txheej txheem ntawm qhov kub thiab txias viscosity (txias pib nrog cov roj khov, ntxiv rau kev hnav ntawm cov twj tso kua mis, yog qhov txaus ntshai nrog kev kub siab thiab tawm los ntawm cov ntsaws ruaj ruaj)! Raws li kev hloov pauv rov qab, nws tsis raug tso cai rau cov laj thawj tau piav qhia saum toj no. Tseeb, nyob ntawm qhov kub thiab txias, qhov hum ntawm lub hwj chim kauj twj tso kua mis yuav tshwm sim.
15 lub zog tswj lub zog zoo tshaj plaws
Kev tshuaj xyuas ntawm 15 qhov zoo tshaj plaws lub zog tswj cov kua dej uas tuaj yeem sau tau. PSF, ATF, Dextron - uas cov kua dej thiab tus nqi yog qhov zoo tshaj plaws rau kev tswj fais fab. Paub meej ntxiv
Thaum siv lub hwj chim steering kua, nws yog tsim nyog tsom rau qhov tsawg kawg nkaus twj tso kua mis kub thiab lub kinematic viscosity ntawm cov roj (rau lub durability ntawm nws cov hauj lwm, nws yuav tsum tsis txhob ntau tshaj 800 m㎡ / s).
Qhov sib txawv ntawm Dexron thiab ATF
Nyob rau hauv cov nqe lus ntawm interchangeability ntawm cov kua, cov tswv tsheb kuj xav tsis tau tsuas yog hais txog lub compatibility ntawm Dexron 2 3, tab sis kuj yog dab tsi yog qhov txawv ntawm Dexron 2 roj thiab ATF. Qhov tseeb, lo lus nug no tsis raug, thiab ntawm no yog vim li cas ... Cov ntawv luv ATF sawv rau Automatic Transmission Fluid, uas txhais tau tias tsis siv neeg kis dej. Ntawd yog, tag nrho cov kua xa hluav taws xob siv hauv kev sib kis tsis siv neeg poob hauv qhov txhais no.
Raws li rau Dexron (tsis hais tiam twg), nws tsuas yog lub npe rau ib pawg ntawm cov kev qhia tshwj xeeb (qee zaum hu ua hom) rau cov dej tsis siv neeg kis tau tus mob tsim los ntawm General Motors (GM). Nyob rau hauv lub npe no, tsis yog tsuas yog tsis siv neeg kis tau tus mob kua, tab sis kuj rau lwm yam mechanisms. Ntawd yog, Dexron yog lub npe dav dav rau cov lus qhia tshwj xeeb uas tau txais los ntawm ntau lub tuam txhab ntawm cov khoom lag luam. Yog li ntawd, feem ntau ntawm tib lub canister koj tuaj yeem pom cov npe ATF thiab Dexron. Tseeb, qhov tseeb, Dextron kua yog tib yam kis tau tus mob kua rau tsis siv neeg kis (ATF). Thiab lawv tuaj yeem sib xyaw, qhov tseem ceeb tshaj plaws yog tias lawv cov kev qhia tshwj xeeb yog nyob rau tib pab pawg.Rau cov lus nug ntawm vim li cas qee cov tuam txhab sau Dexron canisters thiab lwm tus ATF, cov lus teb los rau tib lub ntsiab lus. Dexron kua yog tsim los rau General Motors specifications, thaum lwm tus yog rau lwm manufacturers ' specifications. Tib yam siv rau cov xim cim ntawm canisters. Nws tsis nyob rau hauv txhua txoj kev qhia qhov tshwj xeeb, tab sis tsuas yog qhia (thiab txawm tias tsis tas li) txog cov roj yam twg tau siv los ua cov roj hauv paus hauv kev tsim cov kua dej sib kis tau nthuav tawm ntawm lub txee. Feem ntau, liab txhais tau hais tias lub hauv paus siv cov roj ntxhia, thiab daj txhais tau tias yog hluavtaws.
