Zoletsa kuwuma - Ndi chiyani icho? Mtundu wa zoletsa kuwuma kachitidwe Kutentha

Pakali pano, ndi zoletsa kuwuma ndi mbali yofunika ya galimoto ano. Ndi madzimadzi uyu ali ndi ntchito ya yozizira injini galimoto a, komanso kumathandiza kuti ntchito yolongosoka wa a magetsi. Kufunika kokhala ndi zoletsa kuwuma mofanana ndi kukhalapo kwa mafuta injini, chifukwa milandu onse, pakalibe izi kapena kuti madzi n'kogwiritsa kuwonongeka ndi kutenthedwa ya galimoto galimoto. Ndipo lero, ife kulipira Nkhani osiyana otere chinthu chofunika, monga zoletsa kuwuma ndi.

Ndi chiyani icho?

Zoletsa kuwuma ndi madzi, chomwe ndi zapansi glycolic (kungakhale propylene kapena ethylene glycol), ndi zina zingapo. Otsiriza ntchito angapo - dzimbiri, wosasunthika ndi suppressant. Wokha ndi ethylene glycol antifreezing amadzimadzi njira ndi munthu kuwira mfundo madigiri 200 Celsius. Phula pa maziko a izi anaonekera mu dziko pafupifupi 80 zapitazo. Iwo anayamba kupanga ndi BASF ndi dzina lake "kapena glysantine" (zoletsa kuwuma kwa Kutentha ndi yozizira mkati injini kuyaka). Chotero dzina akugwiritsabe ntchito ndi BASF kuti amanena zinthu zawo coolants.

Kusiyana pakati pa zoletsa kuwuma ndi zoletsa kuwuma

Posachedwapa I anachita zambiri mtsutso pa mmene njira yabwino lembani SOD - zoletsa kuwuma kapena zoletsa kuwuma. Kupeza yankho loona, ife kufotokoza zonse mu dongosolo. Choncho zoletsa kuwuma. Lingaliro la "zoletsa kuwuma" omwe anamasuliridwa kuti English zikumveka ngati "ayezi" wachita kale ntchito pofotokoza madzi opangidwa mu US ndi Europe. Zoletsa kuwuma - ndi zofanana ndi za zoletsa kuwuma. Kusiyana kokha kwagona kuti amapangidwa mwapadera mu mayiko a USSR kale. Kuti ndi zoletsa kuwuma - tinganene, ndi zoletsa kuwuma Russian Komabe, anaonekera okha oyambirira 70 ntchentche Mu zaka zapitazo.

mtundu

Tsopano masitolo galimoto adayamba kumumasula wobiriwira ndipo ngakhale yowala-lalanje zoletsa kuwuma. Ndi chiyani icho? Ndipotu ndi zoletsa kuwuma imodzi, utoto. Ngati opanga zoweta kujambula zinthu zawo mu umodzi, buluu buluu hue, makampani kunja kubala zoletsa kuwuma osiyana (wachikasu, wofiira, ndi zina zotero). zosiyanasiyana amenewa nthawi zina akulowa n'kufika poledzera eni galimoto posankha madzi abwino. Ndipotu kusiyana kwambiri pakati pa zoletsa kuwuma wachikuda ali ayi. Onse a iwo amasiyana chokha chiwerengero cha utoto kupezeka mkati. Choncho, mtundu wa zoletsa kuwuma chabe makampani malonda chiwembu. Iwo akuyesera kuti akope chidwi cha anthu ambiri ogula yowala ndipo yachilendo 'coolants mu njira iyi. Zoletsa kuwuma kwa Kutentha ndi SOD, kaya ndi buluu kapena wobiriwira, n'kofunika ofanana galimoto.

Ndingatani kusakaniza coolant wa zopangidwa osiyana ndi opanga?

Yankho la funso limeneli ndi osokoneza. Kumene, ziziyenda ambiri anadabwa kuona kuti mtundu wina wa zoletsa kuwuma zikhoza kuchepetsedwa ndi madzi ina. Ndipo iwo ali mwina bwino. Zoletsa kuwuma mix angathe kuzikwaniritsa pamene zinthu zonse nambala yomweyo zina. makampani osiyanasiyana ntchito zina zosiyanasiyana mankhwala awo, kotero si nthawi zonse ngati madzi adzakhala yogwirizana ndi mzake. zoletsa kuwuma mtundu zilibe kanthu pano. Inde, ethylene glycol zoletsa kuwuma aliyense ali zikuchokera chomwecho. Sakanizani zingakhale mu kufanana kulikonse. Koma ndi zina za zinthu ndi yosiyana. Ena, malingana ndi Mlengi, kungakhale mankhwala zochita kupanga (mankwala, amine, ndi boron nitride), winayo - mbadwo watsopano wa mankhwala. Choncho, kulumikiza zinthu zonsezi, lubricating ndi antirust katundu, lomwe kale anapereka coolant poipa kangapo. Mapeto kwa ichi ndi chimodzi chokha - kusakaniza zoletsa kuwuma osiyana popanda kuwerenga zikuchokera zina ali osavomerezeka. Apo ayi izi zidzapangitsa kuti kutenthedwa pafupipafupi, ndipo safanana, kuti muchepetse moyo utumiki wa galimoto ndi Kutentha kachitidwe.

Kodi si kugula yabodza?

Mwatsoka, ngakhale mu Russia, kapena Europe palibe muyezo umodzi izo zikanakhala zonse moyo wa coolant lapansi. M'mawu ena, odana ndi amaundana chitsimikizo sikowumiriza. Choncho, kuona ngati ndi mkulu khalidwe zoletsa kuwuma kapena yabodza, palibe kafukufuku wapadera sangathe.

Komabe, si onse opanda chiyembekezo. Kuchepetsa chiopsezo kugula onyenga mungathe, bola ngati katundu amene asankhidwa molondola. Pogula zoletsa kuwuma ayenera kulabadira zinthu izi:

1. Place yogula. Ngati inu kugula katundu ku masitolo apadera, pali chiopsezo kupeza yabodza yafupika kwambiri. Kumbukirani kuti bwino kwambiri wodziwika mu mzinda (dera), mfundo ili, zokayikitsa mutatulukira chisokonezo ndi. masitolo amenewa kwenikweni anayesedwa dyera kupereka zikalata zonse ndi zikalata khalidwe anapulumutsa KATUNDU.
2. Information pa chizindikiro. Posankha, kuwerenga zolemba pa chizindikiro. Pa canister ndi apamwamba zoletsa kuwuma nthawi zonse amalembedwa angapo a Lachiwiri monga wopanga muyezo. Last zambiri amapezeka mu mfundo zoletsa kuwuma. Muyeneranso kuyang'ana pa tsiku lotha ndi tsiku kupanga katundu. Ndipo potsiriza, tiona kuti zonse ndi udindo winanso opanga weniweni nthawi zonse amasonyeza pa chizindikiro ndondomeko ndi adiresi. Ngati zoletsa kuwuma si mtundu wa Mlengi ndi kusowa deta pa specifications, ndiye unatsanuliridwa njira garaja, kuti ndi zabodza.
3. Mtengo. M'pomveka zoletsa kuwuma, zomwe zikhoza kugulidwa pa mtengo wa chomwecho mwa mawu a mphamvu madzi mchere, si khalidwe. Komanso mtengo kwambiri kugula zoletsa kuwuma Sikuti. Ndi bwino kuti asasiye "golide zikutanthauza" Mfundo bwino, kutali zedi kupeza ndemanga pa intaneti za wopanga izi. Apo ayi zoletsa kuwuma kachitidwe galimoto Kutentha Sindizakubweretsanso iliyonse yabwino. mota adzakhala nthawi zonse ukagwira, ndi uvuni kudyetsa mpweya ozizira okha.

Kusakaniza zoletsa kuwuma mafuta

Panali mafuta zoletsa kuwuma. Kodi kuchita? Ambiri, zodabwitsazi ndi osowa kwambiri tanthauzo ndi zoweta magalimoto (zambiri zoletsa kuwuma kungoti "thovu" mu thanki patsogolo). Koma zoyenera kuchita imeneyi? Kuyamba, tikuona kuti kwambiri magalimoto masiku ano makamaka kunja, zida ndi kutentha wapadera exchanger, limene lili pa nyumba ya sefa mafuta. Pa nthawi imeneyi, kuwombola mafuta amapezeka ndi coolant lapansi. Ndipo ngati kutentha anataya kuchucha yapita, n'zotheka kusakaniza zinthu ziwiri ukuwonjezeka galimoto kwambiri.

Zodabwitsa ndizakuti, injini kuthamanga Mwina ozama mafuta SOD ndi apamwamba kuposa zachabe (ngakhale ali wokwera mtengo kwambiri odana ndi amaundana). Ndi chiyani icho? Ndipotu zonse lophweka. chodabwitsa chifukwa cha kuthamanga mkati dongosolo. Pamene galimoto ndi anangotsika patapita mphindi pang'ono mlingo wake zayamba liri kuthamanga mumlengalenga.

Zotsatira za kusakaniza mafuta ndi zoletsa kuwuma

Kumbukirani, ethylene glycol, wothira mafuta, akhoza kwambiri kusokoneza ntchito ya injini ndi zigawo zake, ngati kuchuluka kwa wokhutira kuposa chizindikiro cha 0,35 peresenti, ayenera yomweyo funsani siteshoni utumiki. Apo ayi, ana amakumana ndi injini ndi dzimbiri kuwonongeka wochuluka filimu pa makoma yamphamvu.

Kodi tiyenera kuchita kangati Ine kusintha zoletsa kuwuma?

Kodi ndi chifukwa chiyani mafuta, ife kale anapeza. Tsopano m'malo pafupipafupi. Ndipo kusintha zoletsa kuwuma tikulimbikitsidwa iliyonse makilomita 60-80 zikwi, ndipo makamaka pamaso pa isanayambike yozizira ozizira. Ndi watsopano odana ndi amaundana ndi mbaula, ndi injini adzathamanga bwino kwa miyezi ingapo ndipo ngakhale zaka.
