Service fluid ATP Dextron

ATF Dexron service fluid (Dexron) ndi chinthu chofala kwambiri m'misika yamayiko osiyanasiyana ndipo chimagwiritsidwa ntchito mwachangu ndi eni ake amitundu yosiyanasiyana yamagalimoto. Madzi amadzimadzi, omwe amatchedwanso Dextron kapena Dextron (ndipo m'moyo watsiku ndi tsiku, mayina osalondola amagwiritsidwa ntchito kwambiri), ndimadzimadzi omwe amagwira ntchito pamagetsi odziwikiratu, chiwongolero chamagetsi ndi njira zina ndi misonkhano.

M'nkhaniyi, tiwona zomwe Dexron ATF ndi, komwe ndi liti madzimadziwa adapangidwa. Komanso, chidwi chapadera chidzaperekedwa kwa mitundu yamadzimadzi iyi yomwe ilipo komanso momwe mitundu yosiyanasiyana imasiyanirana, yomwe Dextron amadzaza ma transmissions odziwikiratu ndi mayunitsi ena, etc.

Mitundu ndi mitundu yamadzimadzi Dexron

Poyamba, lero mungapeze madzi kuchokera ku Dexron 2, Dexron IID kapena Dexron 3 mpaka Dexron 6. Ndipotu, mtundu uliwonse ndi mbadwo wosiyana wa madzi opatsirana, omwe amadziwika kuti Dexron. Chitukukochi ndi cha General Motors (GM), chomwe chidapanga madzi ake otumizira Dexron mu 1968.

Kumbukirani kuti makampani opanga magalimoto m'zaka zimenezo anali pa siteji ya chitukuko yogwira, automakers lalikulu kulikonse anayamba kulolerana ndi miyezo mafuta ndi kufala madzimadzi. M'tsogolomu, kulolerana uku ndi zofotokozera zinakhala zofunikira kwa makampani a chipani chachitatu omwe amapanga madzi amagalimoto.

• Tiyeni tibwerere ku Dextron. Pambuyo pa kutulutsidwa kwa mbadwo woyamba wamadzimadzi otere, zaka 4 pambuyo pake, GM inakakamizika kupanga mbadwo wachiwiri wa Dextron.

Chifukwa chake ndi chakuti mafuta a whale adagwiritsidwa ntchito mwachangu ngati chosinthira mikangano m'badwo woyamba, ndipo mafuta a giya adakhala osagwiritsidwa ntchito chifukwa cha kutentha kwambiri pakutumiza kwadzidzidzi. Chilinganizo chatsopano amayenera kuthetsa mavuto, amene anapanga maziko a Dexron IIC.

M'malo mwake, mafuta a whale asinthidwa ndi mafuta a jojoba monga chosinthira mikangano, ndipo kukana kutentha kwa mankhwalawa kwasinthidwanso. Komabe, ndi zabwino zonse, zolembazo zinali ndi vuto lalikulu - kuwonongeka kwakukulu kwa zinthu zodziwikiratu.

Pachifukwa ichi, ma corrosion inhibitors awonjezeredwa kumadzimadzi opatsirana kuti asapangike dzimbiri. Kusintha kumeneku kudapangitsa kuti pulogalamu ya Dexron IID ikhazikitsidwe mu 1975. Komanso pakugwira ntchito, zinapezeka kuti madzi opatsirana, chifukwa cha kuwonjezera kwa anti-corrosion phukusi, amayamba kudziunjikira chinyezi (hygroscopicity), zomwe zimabweretsa kuwonongeka kwa katundu.

Pazifukwa izi, Dexron IID idachotsedwa mwachangu ndikuyambitsa Dexron IIE, yomwe ili ndi zowonjezera zomwe zimateteza ku chinyezi ndi dzimbiri. N'zochititsa chidwi kuti m'badwo uwu wa madzi wakhala theka-synthetic.

Komanso, pokhulupirira kuti ntchitoyi ndi yothandiza, patangopita nthawi yochepa kampaniyo idakhazikitsa madzi atsopano okhala ndi mawonekedwe abwino pamsika. Choyamba, ngati mibadwo yam'mbuyomu inali ndi mchere kapena semi-synthetic maziko, ndiye kuti madzi atsopano a Dexron 3 ATF amapangidwa pakupanga.

Zatsimikiziridwa kuti yankho ili ndi losagwirizana ndi kutentha kwakukulu, lili ndi mafuta abwino kwambiri komanso otetezera katundu, ndipo limasunga madzi otentha kutentha (mpaka -30 digiri Celsius). Unali m'badwo wachitatu womwe udakhala wapadziko lonse lapansi ndipo unkagwiritsidwa ntchito kwambiri potengera ma transmissions, chiwongolero chamagetsi, ndi zina zambiri.

• Mpaka pano, m'badwo waposachedwa umatengedwa ngati Dexron VI (Dextron 6), wopangidwira kufala kwa Hydra-Matic 6L80 sikisi-liwiro. Chogulitsacho chinalandira mphamvu zokometsera bwino, kuchepetsedwa kwa viscosity ya kinematic, kukana kuchita thovu ndi dzimbiri.

Wopanga amayikanso zamadzimadzi ngati mawonekedwe omwe safuna kusinthidwa. M'mawu ena, mafuta amenewa amatsanuliridwa mu kufala basi kwa moyo wonse wa unit.

Zoonadi, mafuta a gearbox ayenera kusinthidwa makilomita 50-60, koma n'zoonekeratu kuti katundu wa Dextron 6 wasintha kwambiri. Monga momwe zimasonyezera, Dextron VI imatayanso katundu wake pakapita nthawi, koma imayenera kusinthidwa nthawi zambiri kusiyana ndi Dextron III yachikale.

• Chonde dziwani kuti zodziwikiratu kufala zamadzimadzi kwa nthawi yaitali amapangidwa ndi opanga osiyanasiyana, pamene mankhwala amapangidwa pansi pa dzina Dexron. Ponena za GM, nkhawa yakhala ikupanga mtundu uwu wamadzimadzi kuyambira 2006, pomwe opanga mafuta ena akupitiliza kupanga Dextron IID, IIE, III, ndi zina.

Ponena za GM, bungweli silili ndi udindo pazabwino ndi katundu wa mibadwo yam'mbuyomu yamadzimadzi, ngakhale akupitiliza kupangidwa molingana ndi muyezo wa Dexron. Zingadziŵikenso kuti masiku ano Dexron madzi akhoza kukhala muyezo kapena HP (mkulu ntchito) kwa transmissions basi ntchito mu zinthu kwambiri.

Palinso Dexron Gear Mafuta osiyanitsa ndi zokokera, Dexron Manual Transmission Fluid for manual transmissions, Dexron Dual Clutch Transmission Fluid for dual-clutch robotic gearboxes, Dexron for power chiwongolero ndi zigawo zina ndi makina. Pali zambiri zoti General Motors akuyesa m'badwo waposachedwa wamadzimadzi kuti ugwiritsidwe ntchito ngati mafuta amagetsi a CVTs.

Ndi Dexron yoti mudzaze ndipo ndizotheka kusakaniza Dexron

Choyamba, ndikofunikira kusankha mtundu wamafuta omwe atha kutsanuliridwa m'bokosi. Chidziwitso chiyenera kufunidwa mu bukhuli, mutha kuwonanso zomwe zikuwonetsedwa pa dipstick yotumizira mafuta.

Ngati tsinde liri ndi chizindikiro cha Dexron III, ndiye kuti ndi bwino kutsanulira mtundu uwu, womwe ndi chitsimikizo cha ntchito yabwino ya bokosi. Ngati muyesa kusintha kuchokera kumadzi ovomerezeka kupita ku china chilichonse, ndiye kuti zotsatira zake zimakhala zovuta kudziwiratu.

Tiyeni tipite kumeneko. Musanagwiritse ntchito mtundu umodzi kapena wina wa Dexron ATF, m'pofunika kuganizira payokha nyengo imene galimoto adzakhala ndi kufala basi. GM imalimbikitsa kugwiritsa ntchito Dextron IID m'madera omwe kutentha sikutsika pansi -15 digiri, Dextron IIE mpaka -30 madigiri, Dexron III ndi Dexron VI mpaka -40 digiri Celsius.

Tsopano tiyeni tikambirane za kusakaniza. General Motors palokha imapanga malingaliro osakanikirana ndi osinthika padera. Choyamba, mafuta ena omwe ali ndi luso lamakono akhoza kuwonjezeredwa ku voliyumu yayikulu yamadzimadzi opatsirana pokhapokha pa malire omwe amatsimikiziridwa mosiyana ndi opanga opatsirana.

Komanso, mukasakaniza, muyenera kuyang'ana pa maziko (synthetics, semi-synthetics, mineral oil). Mwachidule, nthawi zina zimakhala zotheka kusakaniza madzi amchere ndi semi-synthetics, komabe, posakaniza zopangira ndi mafuta amchere, zosafunika zimatha kuchitika.

Mwachitsanzo, ngati mutasakaniza mineral Dextron IID ndi kupanga Dextron IIE, mankhwala amatha kuchitika, zinthu zimachulukana zomwe zingayambitse kulephera kutumiza ndi kutayika kwa madzimadzi.

Timalimbikitsanso kuwerenga nkhaniyi ngati mafuta a gear akhoza kusakanikirana. M'nkhaniyi, muphunzira za kusakaniza mafuta zida, komanso zimene muyenera kuganizira posakaniza mafuta mu gearbox galimoto.

Pa nthawi yomweyo, Dextron IID ore akhoza kusakaniza Dextron III. Pankhaniyi, palinso zoopsa, koma zimachepetsedwa, chifukwa nthawi zambiri zowonjezera zamadzimadzizi zimakhala zofanana.

Chifukwa cha kusinthasintha kwa Dexron, ndiye kuti Dexron IID ikhoza kusinthidwa ndi Dexron IIE mumayendedwe aliwonse odziwikiratu, koma Dexron IIE sayenera kusinthidwa kukhala Dexron IID.

Komanso, Dexron III akhoza kutsanuliridwa mu bokosi, kumene Dexron II madzi ntchito. Komabe, kubwezeretsanso (kubweza kuchokera ku Dextron 3 kupita ku Dextron 2) ndikoletsedwa. Kuphatikiza apo, ngati kuyikako sikumapereka mwayi wochepetsera kugundana, m'malo mwa Dexron II ndi Dextron III sikuloledwa.

N’zoonekeratu kuti zimene zili pamwambazi n’zachitsogozo chokha. Monga momwe zimasonyezera, ndikwabwino kudzaza bokosilo ndi njira yokhayo yomwe wopanga amalimbikitsa.

Ndizovomerezekanso kugwiritsa ntchito ma analogues, osinthidwa pang'ono potengera katundu ndi zizindikiro. Mwachitsanzo, kusintha kuchokera ku Dexron IIE kupanga kupanga Dexron III (ndikofunikira kuti maziko a mafuta oyambira ndi phukusi lalikulu lowonjezera likhalebe osasintha).

Ngati mwalakwitsa ndikudzaza kufala kwamadzimadzi ndi madzimadzi osavomerezeka, mavuto angabwere (kutsetsereka kwa disc slip, viscosity inevenness, kuthamanga kwamphamvu, etc.). Nthawi zina, zotengera zimatha kutha mwachangu, zomwe zimafunikira kukonza zodziwikiratu.

Tiyeni tiwone zotsatira

Poganizira zomwe tafotokozazi, tinganene kuti Dexron ATF 3 ndi Dexron VI mafuta opatsirana masiku ano ndi osinthika kwambiri komanso oyenera kutengera makina ambiri, chiwongolero chamagetsi, komanso zigawo zina ndi machitidwe a magalimoto a GM.

Timalimbikitsanso kuwerenga nkhani ya mafuta otumizira mafuta a Lukoil. M'nkhaniyi, muphunzira za ubwino ndi kuipa kwa Lukoil gear mafuta kufala pamanja, komanso zimene muyenera kuganizira posankha mankhwala. Komabe, kulolerana ndi malangizo ayenera kuphunzira padera pa nkhani iliyonse, chifukwa mabokosi akale sizingakhale bwino kusintha kuchokera Dexron 2 kuti Dexron 3. Ndikofunikiranso kukumbukira kuti kukweza kumtunda wapamwamba nthawi zambiri kumakhala bwino (kuchokera ku Dexron IIE kupita ku Dexron3, mwachitsanzo), koma nthawi zambiri sikuvomerezeka kubwereranso kuchokera ku njira yamakono yopangira zinthu zakale.

Pomaliza, tikuwona kuti ndi bwino kugwiritsa ntchito nthawi yake yoyenera kugwiritsa ntchito madzi amadzimadzi omwe amaperekedwa ndi wopanga, komanso kusintha mafuta mumayendedwe odziwikiratu, chiwongolero chamagetsi, ndi zina zotere munthawi yake. kusakaniza, komanso pamene kusintha kuchokera ku mtundu wina wa ATF kupita ku wina .
