Brake fluid "Neva". Kumvetsetsa magawo

Kodi Neva brake fluid ndi mtundu wanji?

Zizindikiro za Organoleptic zomwe zimaweruza kuyenera kwa ma brake fluids kuti agwiritsidwe ntchito ndi awa:

• chromaticity;
• palibe matope a makina;
• kusapatukana panthawi yosungirako nthawi yayitali.

Nthawi yomweyo, mtundu wa index si wachilengedwe, koma umangowonetsa kuchuluka kwa zowonjezera zomwe zimalowetsedwa mu brake fluid kuti zipititse patsogolo luso lake lopaka mafuta komanso kuziziritsa, luso la okosijeni ndi kukhazikika kwa nambala ya asidi. Chifukwa chake, Neva iyenera kugulidwa pamapaketi owonekera omwe amakwaniritsa zofunikira za GOST 1510-76, ngakhale izi zingakhudze mtengo wa chinthucho.

Malinga ndi mafotokozedwe a TU 6-09-550-73, Neva brake fluid (komanso kusinthidwa kwake Neva-M) ayenera kukhala ndi mtundu wobiriwira wachikasu ndi kuthekera kwa opalescence pang'ono (kuchuluka kwa kuwala kobalalika pa kutentha komwe kumayandikira kwambiri). Mtundu wa madzi omwe amagwiritsidwa ntchito kale ndi wakuda pang'ono.

Kupatuka kulikonse kwamtundu kumalumikizidwa ndi kuchuluka kwa zolimbitsa thupi komanso zowonjezera zowonjezera kuzinthu zazikulu - ethyl carbitol ndi boric acid esters. "Neva" ya mtundu wosiyana ndi osavomerezeka ntchito pa otsika kutentha yozungulira, popeza kuwonjezeka mamasukidwe akayendedwe kumabweretsa kuwonjezeka kwambiri mphamvu ya kukanikiza ananyema pedal, ndi magalimoto okonzeka ndi ABS, zingachititse kulephera kwa dongosolo lino. .

makhalidwe a

Neva universal brake fluid idapangidwa nthawi ina kuti igwiritsidwe ntchito pamagalimoto apanyumba monga Moskvich ndi Zhiguli, chifukwa chake imagwirizana kwathunthu ndimadzimadzi amabuleki monga Tom ndi Rosa. Mawonekedwe ake akuthupi ndi makina ndi awa:

1. Kutentha kosiyanasiyana kogwiritsa ntchito - ± 50⁰C.
2. Kutentha kwapakati - 195⁰C.
3. Kinematic viscosity, cSt, pa kutentha mpaka 50⁰C - osapitirira 6,2.
4. Kinematic mamasukidwe akayendedwe, cSt, pa kutentha mpaka -40⁰C - osapitirira 1430.
5. Kuwononga zitsulo zina sikungatheke.
6. Kutentha kwa chiyambi cha thickening ndi -50⁰C.
7. Kusintha kwa kutentha kwa kutentha pambuyo posungira nthawi yayitali - ± 3⁰C.
8. Kuwala - 94⁰C.
9. Kutupa kwa volumetric kwa ziwalo za rabara pa kutentha mpaka 120⁰C, osapitirira 3%.

Kuwonongeka pang'ono kumatheka pokhapokha ngati madzimadzi a brake akumana ndi zida za aluminiyamu kwa nthawi yayitali.

Zotsatira za ntchito

Ma brake fluids Neva ndi Neva M ali m'gulu la DOT-3. Malinga ndi muyezo wapadziko lonse lapansi, kupatuka kwa kutentha kovomerezeka kwa zakumwa "zouma" ndi "zonyowa" za kalasi iyi ndi 205, motsatana.⁰C ndi 140⁰C. Kuphatikiza apo, ndi kusungirako kosasindikizidwa, kuyamwa kwamadzi pachaka mpaka 2 peresenti ya voliyumu yake kumaloledwa. Chifukwa chake, chinyezi chambiri chimayambitsa dzimbiri mu ma brake system, zomwe zimatha kuyambitsa mavuto monga kutsekereza kwa fuse kapena kulephera kwa pedal.

DOT-3 ndi DOT-4 brake fluids amatha kusinthana chifukwa ali ndi maziko ofanana. Tikumbukenso kuti angapo opanga Neva ndi analogues (makamaka Neva-super, amene amapangidwa ndi Shaumyan Plant OJSC, St. Petersburg) kulengeza ntchito polyalkylethylene glycol monga chigawo chachikulu cha zikuchokera. Komabe, mankhwala a ethyl carbitol ndi polyalkylethylene glycol ali pafupi, choncho palibe chifukwa chopewa kusakaniza Neva kuchokera kwa opanga osiyanasiyana.

Chofunikira chogwirira ntchito cha Neva brake fluid ndi kawopsedwe kake, komwe kuyenera kuganiziridwa potsatira malamulo otetezedwa mukamagwiritsa ntchito.

Mtengo wa brake fluid "Neva" ndi zofanana zake zimadalira ma CD ake:

• Muzitsulo za 455 ml - kuchokera ku 75 ... 90 rubles.
• Muzitsulo za 910 ml - kuchokera ku 160 ... 200 rubles.

Chifukwa chiyani brake fluid imasanduka yakuda?
