ʻO nā hiʻohiʻona o nā wai kaʻa mai Lukoil
Nāʻano
ʻO nā koi koʻikoʻi no ka wai hoʻomaha ka paʻa o kā lākou thermophysical parameter i ka laulā ākea ākea a me ka loaʻa ʻole o nā hopena ʻino ma nā ʻāpana o ke kaʻa. ʻO ka mea mua o Lukoil DOT-4 - "troika" - ua hoʻololi nui ʻia no nā ʻōnaehana pahu pahu, a ua hoʻohana ʻia e nā mea nona nā kaʻa i hana ʻia ma ka home. No laila, i kēia hihia, ʻo ka hoʻololi ʻana i kahi wai hou he mea koho. ʻO kekahi mea ʻē aʻe, ʻo nā kaʻa me nā disc brakes: ma muli o ko lākou hoʻonui ʻana i ka hana i ka braking, ua ikaika loa lākou, a ʻo DOT-3, he 205 wale nō. °C, ʻoi aku ka hewa.
Ua loaʻa ke ala i waho i ka hoʻololi ʻana i ka mea nui - ma kahi o ka glycol maʻamau i DOT-4, ua hoʻohana ʻia kahi hui o nā esters a me ka wai boric. Hāʻawi nā mea pono i ka hoʻonui ʻana i ka helu hoʻolapalapa (a hiki i 250 °C), a ʻo ka boric acid e hoʻokūpaʻa i ka hana a pale i ke ʻano o nā mole wai i loko o ka hoʻohui ʻana o ka wai kaʻa (hiki kēia i ka wā lōʻihi o ka hana ʻana o ke kaʻa a me ka haʻahaʻa kiʻekiʻe). I ka manawa like, ʻaʻole i manaʻo ʻia kekahi a i ʻole nā mea ʻē aʻe he mea pōʻino i ke kaiapuni, no laila, ʻaʻohe mea ʻawaʻawa ʻo Lukoil DOT-4 i ka wā o kāna hana. ʻO nā mea ʻē aʻe - nā mea hoʻohui anti-foam, antioxidants, corrosion inhibitors, e like me nā hopena hōʻike, neʻe mai ka "ʻekolu" a i ka "ʻehā", no ka mea, ua hōʻoia ʻia ka maikaʻi o nā ʻāpana.
ʻO kahi hemahema kūlohelohe o ka haku mele hou ʻo ia kona kumukūʻai kiʻekiʻe, e pili ana i nā pilikia ʻenehana i ka hoʻomākaukau ʻana i nā esters. Hiki i nā mea nona nā kaʻa me nā disc brakes ke manaʻolana i ka hala ʻana o ka manawa, e ʻike ʻo Lukoil i kahi ala liʻiliʻi o ka manawa e esterify i ka meaʻai.

ʻO ka hoʻonohonoho ʻana i nā loiloi mea hoʻohana, hiki iā mākou ke huki i kēia mau hopena:
- ʻOiai ke ʻano like o waho o nā ʻano hana, ʻaʻole ʻōlelo ʻia e hui pū me DOT-3 a me DOT-4 i ka ʻōnaehana hoʻokahi. I ka hala ʻana o ka manawa, puka mai kahi precipitate, inā ʻaʻole ʻike ʻia i ka manawa kūpono, e hoʻoulu ai i nā pilikia he nui, mai ka hoʻomaʻemaʻe ʻana i ka ʻili a hiki i ka hoʻomaʻamaʻa banal o nā kaʻa me ke ʻano o kahi ʻala. Me he mea lā, ke kū mau nei kekahi ʻano hana kemika ma waena o ka ethylene oxide a me ka ether.
- Mālama ʻo Lukoil DOT-3 i ka manawa i kauoha ʻia no 4 mau makahiki. Hāʻawi ʻia i nā mahana maʻamau ma nā ʻaoʻao braking, ʻaʻole maikaʻi kēia.
- ʻAʻohe hopena maikaʻi ʻole i ke kūlana o nā ʻili o ka ʻōnaehana brake, ʻo ia hoʻi, hana pono nā mea hoʻopiʻi corrosion i kā lākou kuleana.
- ʻO ka hapa nui o nā mea kaʻa i kā lākou loiloi e hōʻike ana i ka maikaʻi o Lukoil DOT-4 e hilinaʻi nui ʻia i ka mea hana. ʻOi aku ka maikaʻi ma mua o ka DOT-4 i hana ʻia ma Dzerzhinsk, akā hana ʻia ma Obninsk. Ua ʻōlelo ka poʻe loea ʻaʻole lawa ke kumu i kēia manawa (e like me ka loaʻa ʻana o ka wai hoʻoheheʻe i hōʻike ʻia) kumu hana o ka ʻoihana.
Nui nā hopena maʻamau: maikaʻi ke ʻano o Lukoil DOT-4, a ʻo nā mea hoʻohui a pau i haʻi ʻia e ka mea hana e hoʻokō i kā lākou mau hana. He mea maopopo, pono e makaala mau i ka mea make a me ka hikiwawe o ka wai kaa, a i ka lawelawe ana ia lakou, e malama i na mea a pau i kauohaia. ʻAʻole ʻokoʻa ka DOT-4.
ʻO ke kumu kūʻai o Lukoil DOT-4 brake fluid mai 80 rubles. no ka pahu 0,5 lita. a mai 150 rubles. no ka pahu 1 lita.
