Kodi osiyana ndi zoletsa kuwuma zoletsa kuwuma ndi zimene ndicho mfundo izi?

Galimoto ano ali okonzeka ndi dongosolo kuzirala, mmene muli madzi monga zoletsa kuwuma. Nthawi zina, m'malo ziziyenda anatsanulira mu thanki zoletsa kuwuma kukula. Ndipotu, ntchito za madzi onse ali ofanana. Koma chifukwa pali maganizo, iwo angathe amati kokha ntchito pa mtundu winawake wa galimoto? Pa nkhani imeneyi, ife tiri lero ndi kutchereza. Choncho, chimene ndi chosiyana kuchokera zoletsa kuwuma zoletsa kuwuma?

The zikuchokera zoletsa kuwuma

Ndipotu kusiyana iwo ali. Koma pamaso funso limeneli mwachindunji, tiyeni mvetserani kwa zoletsa kuwuma zikuchokera. dzina uyu adagwiridwa ndi cholinga. Kumasulira kwa Greek "odana" amatanthauza "ndi", "frieze" - kuchokera English "amaundana." M'chizungumo, mawuwa amanena za "coolant" kwa injini ya galimoto. Ndiko kuti, zinthu yogwira amamuchititsa kusunga mphamvu yake pa subzero (-30-40 madigiri Celsius), ndipo prohibitively mkulu (100 ° C) kutentha. N'chifukwa chake amatchedwa "antizamerzaykoy".

Kukhala enieni a funso la chimene chiri chosiyana ndi zoletsa kuwuma coolant, ndi Dziwani kuti yotsirizira ndi amadzimadzi njira ya chuma kutentha zosagwira, wokhoza kusunga katundu wawo kwa nthawi yaitali pa otsika kutentha. Mu zikuchokera zimapezekanso propylene glycol, glycerol, ethylene glycol ndi mchere zochita kupanga.

Kuti mudziwe zambiri za zoletsa kuwuma

Tsopano palokha ndi zoletsa kuwuma. Mawu amenewa anali woyamba kutchulidwa 70 ntchentche Mu zaka zapitazo, pamene khamu mzere wa galimoto Volga anatsika galimoto yoyamba Vaz-2101. Ndi chitukuko cha mafakitale magalimoto mu USSR kwambiri kuchuluka zofuna coolants, kotero kuti vutoli analenga chida chatsopano n'cholinga ntchito kokha Miphika, "Volga" ndi makina zina za pakhomo. Mu Soviet Union kuti ankaona kuti kusinthidwa patsogolo pa zoletsa kuwuma zoletsa kuwuma. Tsopano Komabe, mfundo "zoletsa kuwuma" sumabala aliyense potsegula zamalankhulidwe mawu a zikuchokera ndi khalidwe. madzi tichipeza ndendende zigawo chimodzimodzi monga "antizamerzayku". Chinthu chokha chimene ndi chosiyana ndi zoletsa kuwuma coolant, choncho ndi malo a ulimi. Woyamba amapangidwa mwapadera mu mayiko a USSR kale. Zoletsa kuwuma imatengedwa mankhwala achilendo ndipo amapezeka mu dziko lathu monga katundu tanthauzo.

khalidwe

Tonse amaganiza kuti zonse kunja (makina, aggregates ndi mbali yawo, kuphatikizapo chomwecho "antizamerzayku") ndi wa khalidwe kuposa mankhwala zoweta. Komabe, mu nkhani ya zoletsa kuwuma kuli chinthu monga quality, kwakukulukulu convergent ndi "kunja" zoletsa kuwuma. Ndipo iye ndi zinthu zina zopangidwa ndi kugwilizana ndi malangizo onse ndi zofunika, ndi Kuwonjezera wa zigawo zikuluzikulu chomwecho. Chinthu chokha chimene angakhale osiyana, kotero ndi lolembedwa pa mphamvu, mtengo, ndi mtundu (zoletsa kuwuma nthawi zonse buluu, pamene zoletsa kuwuma akhoza kukhala wofiira, wobiriwira, ndipo ngakhale wofiirira). Komabe, nthawi zina, zoletsa kuwuma angakhale zosalongosoka kapena wasokoneza ndi. Nthawi zambiri osowa, koma nthumwi thobvu mu posungira ndi osafunika, makamaka ngati injini ndi pa kutentha pazipita.

Choncho, funso la chimene ali osiyana ndi zoletsa kuwuma zoletsa kuwuma, mfundo imodzi yokha: yemweyo zinthu zikuchokera ndi katundu ndipo angagwiritsidwe ntchito mwangwiro pa galimoto iliyonse. Komabe, overpaying kwa kunja "antizamerzayku", inu kuchepetsa chiopsezo kugula achinyengo. Mu Russia, ngakhale kuti amatsatira mfundo za ulimi, monga Germany kapena Poland.
