Makhalidwe amadzimadzi a brake ochokera ku Lukoil

makhalidwe a

Zofunikira zazikulu zamadzimadzi ophwanyidwa ndi kukhazikika kwa magawo awo a thermophysical mumitundu yayikulu kwambiri yotentha komanso kusakhalapo kwa zotsatirapo zoyipa pamagawo agalimoto. Kumayambiriro kwa Lukoil DOT-4 - "troika" - idasinthidwa makamaka pama brake system, ndipo idagwiritsidwa ntchito ndi eni magalimoto opangidwa m'nyumba. Choncho, pamenepa, kusintha kwa madzi atsopano ndikofunika. Chinthu chinanso ndi magalimoto okhala ndi mabuleki a disk: chifukwa cha kuchuluka kwawo kwa braking, amawotcha mwamphamvu kwambiri, ndipo DOT-3, yokhala ndi malo otentha a 205 okha. ^°C, zimakhala zovuta kwambiri.

Njira yotulukira idapezeka posintha gawo lalikulu - m'malo mwa glycol wamba mu DOT-4, osakaniza a esters ndi boric acid adagwiritsidwa ntchito. Zinthu zofunika kwambiri zimathandizira kuwonjezereka kwa kuwira (mpaka 250). ^°C), ndi asidi boric kukhazikika ntchito ndi kupewa maonekedwe a mamolekyu amadzi mu zikuchokera madzimadzi ananyema (izi n'zotheka pa ntchito yaitali galimoto ndi pa chinyezi mkulu). Panthawi imodzimodziyo, palibe chimodzi kapena chigawo china chomwe chimaonedwa kuti ndi chovulaza chilengedwe, choncho, Lukoil DOT-4 brake fluid alibe kawopsedwe panthawi yake. Zina zonse - zowonjezera zotsutsana ndi thovu, antioxidants, corrosion inhibitors, malinga ndi zotsatira za mayesero, zimachoka ku "zitatu" mpaka "zinayi", popeza mphamvu za zigawozo zinatsimikiziridwa motsimikizika.

Kuwonongeka kwachilengedwe kwa mapangidwe atsopano ndi mtengo wake wapamwamba, womwe umagwirizanitsidwa ndi zovuta zamakono pokonzekera esters. Eni ake magalimoto ndi mabuleki chimbale akhoza kungoyembekezera kuti m'kupita kwa nthawi, Lukoil adzapeza njira yochepetsera nthawi esterify feedstock.

Kukonza ndemanga za ogwiritsa ntchito, titha kunena zotsatirazi:

1. Ngakhale kufanana kunja kwa formulations, si bwino kusakaniza DOT-3 ndi DOT-4 mu dongosolo ananyema yomweyo. M'kupita kwa nthawi, mawonekedwe a mpweya, omwe, ngati sapezeka m'nthawi yake, amachititsa mavuto ambiri, kuyambira kuyeretsa pamwamba mpaka kutsekemera kwa banal mabuleki ndi maonekedwe a fungo lapadera. Mwachiwonekere, mtundu wina wa kuyanjana kwa mankhwala pakati pa ethylene oxide ndi ether kumachitikabe.
2. Lukoil DOT-3 imasunga nthawi yotsimikizika yazaka zitatu. Poganizira kutentha kwapakati pa mabuleki, izi sizoyipa.
3. Palibenso zotsatira zoipa pa chikhalidwe cha malo a brake system, mwachitsanzo, corrosion inhibitors amachita ntchito yawo moyenera.
4. eni galimoto ambiri ndemanga zawo zikusonyeza kuti khalidwe Lukoil DOT-4 amadalira kwambiri Mlengi. Brake fluid, yomwe imapangidwa ku Dzerzhinsk, ndi yabwino kuposa DOT-4 yomweyi, koma idapangidwa ku Obninsk. Akatswiri amanena kuti chifukwa sikokwanira masiku ano (monga kupeza anafotokoza ananyema madzimadzi) kupanga m'munsi mwa ogwira ntchito.

Pali mfundo zingapo zambiri: zikuchokera "Lukoil DOT-4" ndi zabwino, ndi zina zonse analengeza Mlengi kupirira ntchito zawo. N'zoonekeratu kuti nthawi zonse munthu ayenera kudziwa kawopsedwe ndi flammability wa madzi mabuleki, ndipo powagwira, kutsatira njira zonse zodzitetezera. DOT-4 ndi chimodzimodzi.

Mtengo wa Lukoil DOT-4 brake fluid umachokera ku ma ruble 80. kwa canister ndi voliyumu ya malita 0,5. ndi ma ruble 150. kwa 1 lita imodzi.
