Malangizo Osakaniza a Antifreeze

Kufunika kobwezeretsanso kuchuluka kwamadzimadzi mu injini yoziziritsira injini kumachitika nthawi zambiri, ndipo, monga lamulo, kwa madalaivala omwe amawunika galimotoyo ndikuyang'ana pansi pa hood kuti ayang'ane kuchuluka kwamafuta, kuphulika kwamadzi ndikuyang'ana thanki yowonjezera. imodzi.

Malo ogulitsira magalimoto amapereka mitundu yosiyanasiyana ya antifreeze kuchokera kwa opanga osiyanasiyana, mitundu ndi mitundu. Ndi iti yomwe mungagule "yowonjezera", ngati palibe chidziwitso chazinthu zomwe zidatsanuliridwa mudongosolo kale? Kodi antifreeze angasakanizidwe? Tidzayesa kuyankha funsoli mwatsatanetsatane.

Kodi kusokoneza

Antifreeze yamagalimoto ndi madzi osazizira omwe amayenda munjira yozizirira ndikuteteza injini kuti isatenthedwe.

Ma antifreezes onse ndi osakaniza a glycol okhala ndi madzi ndi zowonjezera zowonjezera zomwe zimapereka antifreeze anti-corrosion, anti-cavitation ndi anti-foam properties. Nthawi zina zowonjezera zimakhala ndi chigawo cha fulorosenti chomwe chimapangitsa kuti zikhale zosavuta kupeza kutayikira.

Ma antifreeze ambiri amakhala ndi madzi 35 mpaka 50% ndipo amawiritsa pa 110⁰C. Pamenepa, maloko a nthunzi amawonekera m'dongosolo lozizira, kuchepetsa mphamvu zake ndikupangitsa kutentha kwa injini.

Pa injini yotentha yothamanga, kupanikizika mu dongosolo lozizira logwira ntchito kumakhala kwakukulu kuposa kuthamanga kwa mumlengalenga, kotero kuti kutentha kumakwera.

Opanga magalimoto m'maiko osiyanasiyana apanga njira zambiri zopangira antifreeze.

Msika wamakono umayendetsedwa ndi mawonekedwe a Volkswagen. Malinga ndi mafotokozedwe a VW, antifreezes amagawidwa m'magulu asanu - G11, G12, G12 +, G12 ++, G13.

Matchulidwe otere adzikhazikitsa pamsika ndipo amawonetsedwa mu malangizo agalimoto.

Kufotokozera mwachidule makalasi ozizira

Chifukwa chake, kufotokozera kwa choziziritsa kukhosi molingana ndi mafotokozedwe a VW:

• G11. Zozizira zachikhalidwe zopangidwa kuchokera ku ethylene glycol ndi madzi okhala ndi silicate zowonjezera. Chapoizoni. Mtundu wobiriwira kapena wabuluu.
• G12. Zozizira za Carboxylate zochokera ku ethylene glycol kapena monoethylene glycol zokhala ndi zowonjezera zowonjezera. Iwo ali ndi mphamvu zosinthira kutentha. Madzi ofiira. Chapoizoni.
• G12+. Zozizira zosakanizidwa ndi organic (carboxylate) ndi inorganic (silicate, acid) zowonjezera. Phatikizani makhalidwe abwino a mitundu yonse ya zowonjezera. Chapoizoni. Mtundu - wofiira.
• G12++. Zozizira zosakanizidwa. Pansi pake ndi ethylene glycol (monoethylene glycol) yokhala ndi zowonjezera zachilengedwe ndi mchere. Amateteza mogwira zigawo za dongosolo yozizira ndi chipika injini. Madzi ofiira. Chapoizoni.
• G13. Mbadwo watsopano wa antifreezes wotchedwa "lobrid". Kusakaniza kwa madzi ndi propylene glycol yopanda vuto, nthawi zina ndi kuwonjezera kwa glycerin. Lili ndi zowonjezera zowonjezera za carboxylate. Wokonda zachilengedwe. Mtundu wofiira, wofiira-violet.

Kodi amaloledwa kusakaniza coolants a mitundu yosiyanasiyana

Mtundu wa antifreeze sikuti nthawi zonse umalola kuti unenedwe ndi gulu linalake. Cholinga chachikulu cha utoto ndikuwongolera kusaka komwe kumatulutsa ndikuzindikira kuchuluka kwa zoziziritsa kukhosi. Mitundu yowala imachenjezanso za kuopsa kwa "kumeza". Opanga ambiri amatsogozedwa ndi miyezo yamalonda, koma palibe chomwe chimawalepheretsa kupenta zoziziritsa kukhosi mumtundu wosasintha.

Kuzindikira kalasi yoziziritsa kukhosi ndi mtundu wa zitsanzo zomwe zatengedwa kuchokera ku chipangizo chozizirira sizodalirika kwathunthu. Pambuyo pogwiritsira ntchito mankhwala ozizira kwa nthawi yaitali, utoto wawo umawola ndipo ukhoza kusintha mtundu. Ndizotetezeka kuyang'ana pa malangizo a wopanga kapena zolemba mu bukhu lautumiki.

Mbuye wosamala yemwe adakonza ndikukonzanso antifreeze amamatira kapepala pa thanki lowonetsa mtundu ndi gulu lamadzi omwe adadzaza.

Molimba mtima, mutha kusakaniza zakumwa za "buluu" ndi "zobiriwira" za gulu la G11, zomwe zimaphatikizapo Tosol yapakhomo. Kuchuluka kwa madzi ndi ethylene glycol kudzasintha, monga momwe zidzakhalire zoziziritsira zokha, koma sipadzakhala kuwonongeka kwachangu kwa kachitidwe kozizira.

Mukasakaniza makalasi a G11 ndi G12, chifukwa cha kuyanjana kwa zowonjezera, ma acid ndi mankhwala osasungunuka amapangidwa omwe amawotcha. Ma Acid ndi aukali ku mapaipi a rabara ndi ma polima, ma hoses ndi zosindikizira, ndipo matope amatseka ma ngalande pamutu wa block, radiator ya chitofu ndikudzaza tanki yotsika ya radiator yozizira ya injini. Kuzungulira kozizirirako kudzasokonekera ndi zotsatirapo zake zonse.

Ndikoyenera kukumbukira kuti zozizira za gulu la G11, kuphatikizapo Tosol yamitundu yonse, zidapangidwa kuti zikhale ndi injini zokhala ndi chitsulo chachitsulo chachitsulo, ma radiator amkuwa kapena amkuwa. Kwa injini yamakono, yokhala ndi ma radiator ndi chipika cha aluminiyamu, zakumwa "zobiriwira" zimatha kuvulaza.

Zigawo za antifreeze zimatha kusanduka nthunzi mwachilengedwe komanso kuwira pamene injini ikugwira ntchito yolemetsa kwa nthawi yayitali kapena kuthamanga kwambiri pamaulendo ataliatali. Chifukwa cha madzi ndi ethylene glycol nthunzi pansi pa kupanikizika mu dongosolo amachoka kupyolera mu "kupuma" valavu mu kapu ya thanki yowonjezera.

Ngati "kuwonjezera" kuli kofunikira, ndi bwino kugwiritsa ntchito madzi osati a gulu lomwe mukufuna, komanso la wopanga yemweyo.

M'mikhalidwe yovuta, pamene mulingo woziziritsa wagwera pansi pamlingo wovomerezeka, mwachitsanzo, paulendo wautali, mutha kugwiritsa ntchito "kuthyolako kwa moyo" kwa mibadwo yam'mbuyomu ndikudzaza dongosolo ndi madzi oyera. Madzi, okhala ndi kutentha kwakukulu komanso kukhuthala kochepa, akanakhala oziziritsa bwino kwambiri ngati sakanayambitsa dzimbiri lazitsulo. Mukathira madzi, pitirizani kuyendetsa galimoto, kuyang'ana kutentha kwa kutentha nthawi zambiri kuposa nthawi zonse ndikupewa kuyimitsa chisanu.

Mukathira madzi munjira yozizirira, kapena antifreeze "yofiira" yokayikitsa yomwe idagulidwa m'mphepete mwa msewu, kumbukirani kuti kumapeto kwa ulendowu muyenera kusintha choziziritsa kukhosi, ndikuyika makina oziziritsa.

Kugwirizana kwa Antifreeze

Kuthekera kwa kusakaniza antifreezes a magulu osiyanasiyana akuwonetsedwa patebulo.

Makalasi a G11 ndi G12 sangasakanizidwe, amagwiritsa ntchito mapaketi osagwirizana; Osavuta kukumbukira:

• G13 ndi G12++, zomwe zili ndi zowonjezera zamtundu wosakanizidwa, zimagwirizana ndi magulu ena aliwonse.

Mukasakaniza zamadzimadzi zosemphana, m'pofunika kutsuka makina ozizirira ndikusintha choziziritsa kukhosi ndi chovomerezeka.

Momwe mungayang'anire kugwirizana

Kudzifufuza kwa antifreeze kuti igwirizane ndi kosavuta ndipo sikufuna njira zapadera.

Tengani zitsanzo - zofanana mu voliyumu - zamadzimadzi mu dongosolo ndi zomwe mwaganiza kuwonjezera. Sakanizani mu mbale yoyera ndikuwona yankho. Kuti mutsimikizire kafukufukuyu, kusakaniza kumatha kutenthedwa mpaka 80-90 ° C. Ngati patatha mphindi 5-10 mtundu woyamba unayamba kusintha kukhala bulauni, kuwonekera kumachepa, chithovu kapena dothi likuwonekera, zotsatira zake zimakhala zoipa, zakumwa sizigwirizana.

Kusakaniza ndi kuwonjezera antifreeze kuyenera kutsogoleredwa ndi malangizo omwe ali m'bukuli, pogwiritsa ntchito makalasi ovomerezeka ndi mitundu yokha.

Kuyang'ana kokha pa mtundu wa zakumwa sikuli koyenera. Chodziwika bwino cha BASF, mwachitsanzo, chimapanga zinthu zake zambiri zachikasu, ndipo mtundu wa zakumwa za ku Japan umasonyeza kukana kwawo kwa chisanu.
