Kodi brake fluid iyenera kusinthidwa kangati?

Bwanji musinthe brake fluid?

Tiyeni tiyambe ndi zoyambira. Brake fluid imagwira ntchito ngati chopatsira mphamvu kuchokera ku master brake cylinder (GTE) kupita kwa ogwira ntchito. Dalaivala akukankhira pa pedal, GTE (pistoni yosavuta kwambiri m'nyumba yokhala ndi valve system) imatumiza kupanikizika kwamadzi kudzera m'mizere. Madzi amadzimadzi amasamutsira kukakamiza kumasilinda ogwirira ntchito (ma calipers), ma pistoni amakulitsa ndikufalitsa mapadi. Mapadiwo amapanikizidwa ndi mphamvu kumalo ogwirira ntchito a ma diski kapena ng'oma. Ndipo chifukwa cha kukangana pakati pa zinthuzi, galimotoyo imayima.

Zinthu zazikulu za brake fluid ndizo:

• kusakhazikika;
• kukana kutentha kutsika ndi kutentha;
• kusalowerera ndale kwa pulasitiki, mphira ndi zitsulo za dongosolo;
• mafuta abwino katundu.

Samalani: katundu wa incompressibility amalembedwa poyamba. Ndiko kuti, madzimadzi ayenera momveka bwino, mosazengereza ndikusamutsa kwathunthu kukakamiza kwa masilindala ogwira ntchito kapena ma calipers.

Brake fluid ili ndi chinthu chimodzi chosasangalatsa: hygroscopicity. Hygroscopicity ndikutha kudziunjikira chinyezi kuchokera ku chilengedwe.

Kuchuluka kwa madzi a brake fluid kumachepetsa kukana kwake kuwira. Mwachitsanzo, madzi a DOT-4, omwe amapezeka kwambiri masiku ano, sangawira mpaka kutentha kwa 230 ° C. Ndipo izi ndizomwe zimafunikira mu US department of Transportation standard. Kuwira kwenikweni kwa madzi abwino a brake kumafika 290 ° C. Pamene 3,5% yokha ya madzi onse amawonjezeredwa ku brake fluid, malo otentha amatsika kufika +155 ° C. Izi ndi pafupifupi 30%.

Dongosolo la braking limapanga mphamvu zambiri zotentha panthawi yogwira ntchito. Izi ndizomveka, chifukwa mphamvu yoyimitsa imachokera ku kukangana ndi mphamvu yaikulu ya clamping pakati pa mapepala ndi disc (ng'oma). Zinthu izi nthawi zina zimatentha mpaka 600 ° C pagawo lolumikizana. Kutentha kwa ma disks ndi mapepala kumasamutsidwa ku ma calipers ndi ma cylinders, omwe amawotcha madzi.

Ndipo ngati kuwira kwafika, madziwo amawira. Mapangidwe a pulagi ya gasi mu dongosolo, madziwo adzataya katundu wake wosagwirizana, pedal idzalephera ndipo mabuleki adzalephera.

M'malo intervals

Kodi brake fluid iyenera kusinthidwa kangati? Pafupifupi, moyo wautumiki wamadzimadzi awa aukadaulo asanaunjike madzi ambiri ndi zaka 3. Izi ndi zoona kwa mitundu ya glycol monga DOT-3, DOT-4 ndi zosiyana zake, komanso DOT-5.1. DOT-5 ndi DOT-5.1/ABS zamadzimadzi, zomwe zimagwiritsa ntchito silikoni ngati maziko, zimagonjetsedwa ndi kudzikundikira kwa madzi, zimatha kusinthidwa kwa zaka 5.

Ngati galimoto ikugwiritsidwa ntchito tsiku lililonse, ndipo nyengo m'derali imakhala yonyowa kwambiri, m'pofunika kuchepetsa nthawi pakati pa m'malo mwa brake fluid ndi 30-50%. Madzi a glycolic pansi pazikhalidwe zovuta zogwirira ntchito amayenera kusinthidwa zaka 1,5-2 zilizonse, madzi a silicone - 1 nthawi pazaka 2,5-4.

Kodi mumadziwa bwanji nthawi yoti musinthe brake fluid yanu?

Ngati simukudziwa nthawi yomwe brake fluid idasinthidwa komaliza (mwaiwala kapena kungogula galimoto), pali njira ziwiri zomvetsetsa ngati ndi nthawi yoti musinthe.

1. Gwiritsani ntchito brake fluid analyzer. Ichi ndi chipangizo chosavuta kwambiri chomwe chimayerekezera kuchuluka kwa chinyezi mu voliyumu ndi kukana kwamagetsi kwa ethylene glycol kapena silicone. Pali mitundu ingapo ya tester iyi ya brake fluid. Pazosowa zapakhomo, chophweka ndi choyenera. Monga momwe chizolowezi chasonyezera, ngakhale chipangizo chotsika mtengo chimakhala ndi cholakwika chochepa, ndipo chikhoza kudaliridwa.
2. Yang'anani mozama brake fluid. Timamasula pulagi ndikuyang'ana mu thanki yowonjezera. Ngati madziwo ali ndi mitambo, ataya kuwonekera kwake, kudadetsedwa, kapena kuphatikizika kwabwino kumawonekera mu voliyumu yake, timasinthadi.

Kumbukirani! Ndi bwino kuiwala kusintha mafuta a injini ndi kulowa mu kukonza injini kusiyana ndi kuiwala za brake fluid ndi kuchita ngozi. Pakati pa madzi onse aukadaulo m'galimoto, chofunikira kwambiri ndi brake fluid.
