Brake fluid "Neva". Ukuqonda amapharamitha

I-Neva brake fluid iyimuphi umbala?

Izinkomba ze-Organoleptic ezihlulela ukufaneleka kwe-brake fluids ukusetshenziswa zifaka:

• i-chromaticity;
• akukho sediment mechanical;
• ukungahlukaniswa ngesikhathi sokugcina isikhathi eside.

Ngesikhathi esifanayo, inkomba yombala ayiyona into enqumayo, kodwa ibonisa kuphela ukwakheka kwezithasiselo ezifakwa ku-brake fluid ukuze kuthuthukiswe amandla ayo okugcoba nokupholisa, ikhono le-oxidation kanye nokuqina kwenombolo ye-asidi. Ngakho-ke, i-Neva kufanele ithengwe emaphaketheni asobala ahlangabezana nezidingo ze-GOST 1510-76, noma ngabe lokhu kuthinta kabi intengo yomkhiqizo.

Ngokusho kokucaciswa kwe-TU 6-09-550-73, i-Neva brake fluid (kanye nokuguqulwa kwayo i-Neva-M) kufanele ibe nombala ophuzi ocebile okungenzeka ukuthi ube ne-opalescence encane (ukunyuka kokukhanya kokukhanya emazingeni okushisa asondela esibucayi). Umbala woketshezi oselusetshenzisiwe umnyama kancane.

Noma yikuphi ukuchezuka kombala kuhlotshaniswa nokwanda kokuhlushwa kwama-thickeners kanye nezithasiselo zokulwa nokugqwala ezingxenyeni eziyinhloko - i-ethyl carbitol ne-boric acid esters. "I-Neva" yombala ohlukile ayinconywa ukuthi isetshenziswe emazingeni okushisa aphansi, njengoba ukwanda kwe-viscosity kuholela ekwandeni okukhulu kwamandla okucindezela i-brake pedal, nasezimotweni ezine-ABS, ngokuvamile zingabangela ukwehluleka kwalolu hlelo. .

Izici

I-Universal brake fluid i-Neva yathuthukiswa ngesikhathi esisodwa ukuze isetshenziswe ezimotweni zasekhaya ezifana ne-Moskvich ne-Zhiguli, ngakho-ke ihambisana ngokugcwele nama-brake fluids afana no-Tom no-Rosa. Izakhiwo zayo ezingokomzimba nezomshini zimi kanje:

1. Ibanga lokushisa lokusetshenziswa okungokoqobo - ± 50⁰C.
2. Iphuzu lokuqala lokubilisa - 195⁰C.
3. I-Kinematic viscosity, cSt, emazingeni okushisa afika ku-50⁰C - akukho ngaphezu kuka-6,2.
4. I-kinematic viscosity, i-cSt, emazingeni okushisa afika ku--40⁰C - akukho ngaphezu kuka-1430.
5. Umsebenzi wokugqwala kwezinye izinsimbi awunalutho.
6. Ukushisa kokuqala kokuqina kungu-50⁰C.
7. Ukushintsha kwezinga lokushisa elibilayo ngemva kokugcinwa isikhathi eside - ±3⁰C.
8. Iphoyinti le-Flash - 94⁰C.
9. Ukuvuvukala kwe-Volumetric yezingxenye zenjoloba emazingeni okushisa afinyelela ku-120⁰C, hhayi ngaphezu kuka-3%.

Ukubola okuncane kungenzeka kuphela uma lolu ketshezi lwebhuleki luxhumene nezingxenye ze-aluminium isikhathi eside.

Izici zohlelo lokusebenza

I-Brake fluids i-Neva ne-Neva M ingeyesigaba se-DOT-3. Ngokwendinganiso yamazwe ngamazwe, ukuphambuka kwamazinga okushisa avumelekile oketshezi "olomile" kanye "nolumanzi" lwalesi sigaba ngu-205, ngokulandelana.⁰C kanye 140⁰C. Ngaphezu kwalokho, ngesitoreji esingavaliwe, ukumuncwa kwamanzi ngonyaka kuze kufike kumaphesenti angu-2 wevolumu yawo kuvunyelwe. Ngakho-ke, umswakama owedlulele udala ukugqwala ohlelweni lwamabhuleki emoto, okungaholela ezinkingeni ezinjengokuvaleka kwentuthu noma ukwehluleka kwezinyawo.

I-DOT-3 kanye ne-DOT-4 ye-brake fluids iyashintshana ngoba inesisekelo esifanayo. Kumele kuqashelwe ukuthi inani labakhiqizi be-Neva kanye nama-analogues ayo (ikakhulukazi, i-Neva-super, ekhiqizwa yi-Shaumyan Plant OJSC, eSt. Petersburg) imemezela ukusetshenziswa kwe-polyalkylethylene glycol njengengxenye eyinhloko yokubunjwa. Kodwa-ke, izakhiwo zamakhemikhali ze-ethyl carbitol ne-polyalkylethylene glycol zifana, ngakho-ke asikho isizathu sokugwema ukuxuba i-Neva kubakhiqizi abahlukene.

Isici esibalulekile sokusebenza kwe-Neva brake fluid ubuthi bayo, okufanele bucatshangelwe lapho kugcinwa imithetho yokuphepha lapho usebenzisa.

Intengo ye-brake fluid "Neva" kanye nama-analogues ayo incike ekufakweni kwayo:

• Ezitsheni ze-455 ml - kusuka ku-75 ... 90 ruble.
• Ezitsheni ze-910 ml - kusuka ku-160 ... 200 ruble.
