Ichashazi le-Brake fluid-4. Yikuphi okungcono?
Ukwakheka nezici ze-brake fluid DOT-4
I-DOT-4 brake fluid ingama-98% e-polyglycols. U-2% osele uyizithasiselo.
Kubalulekile ukuqonda ukuthi kunendinganiso elawula ukwakheka kwama-brake fluids. Leli zinga lidalwe futhi linakekelwa Umnyango Wezokuthutha wase-US. Futhi noma yiluphi uketshezi, kungakhathaliseki umenzi, ngokombono kufanele luhambisane nezici ezibekwe ezingeni, uma kungokomndeni we-DOT. Empeleni, lokhu kuhlale kunjalo, okungenani kuma-brand aziwayo.
Kunezici eziningana ezilawulwayo. Okokuqala, isisekelo. Isisekelo se-DOT-4 brake fluid siqukethe utshwala obuyinkimbinkimbi, okuthiwa ama-polyglycols. Lezi ziphuzo zotshwala zinokuthambisa okuhle, azithinteki nakancane, zihlala zisebenza kuze kufike ku-42°C ngokwesilinganiso, futhi zibilise ezingeni lokushisa elingekho ngaphansi kuka +230°C. Futhi, wonke ama-alcohols weqembu le-glycol abonakala nge-hygroscopicity - ikhono lokumunca amanzi emvelweni futhi ahlakaze amanzi ngevolumu yawo ngaphandle kwe-sediment.
Okwesibili, iphakethe lezithasiselo. Izithasiselo zithuthukisa ukusebenza koketshezi. Ukwakheka kwezithasiselo nakho kulawulwa. Futhi kokubili ngokwemibandela yekhwalithi kanye nenani.
Lokhu kusho ukuthi uma uthenga i-brake fluid ebhalwe ukuthi DOT-4, khona-ke iqinisekisiwe ukuthi iqukethe isethi encane yalezo zingxenye eziqinisekisa ukusebenza kwayo ngaphakathi kwemikhawulo ekhonjiswe yizinga.
Kodwa-ke, umthethonqubo uvumela ukungezwa kwezingxenye zenkampani yangaphandle noma ukwanda kwesilinganiso (hhayi ukuncipha), okungase kuguqule ezinye zezici ze-brake fluid. Ngokuvamile kuba ngcono. Ngokwesibonelo, anciphisa i-viscosity yezinga lokushisa eliphansi, akhuphule indawo abilayo, noma enze uketshezi lungangenwa kalula yinqubo yokumunca umswakama ovela emkhathini.
Uhlolojikelele olufushane lwabakhiqizi
Imakethe yesimanje igcwele okunikezwayo kwe-DOT-4 class brake fluid. Ake sibheke imikhiqizo embalwa eyaziwayo ngokwenyuka kwezindleko, siqale ngeshibhe kakhulu.
- Dzerzhinsky DOT-4. Ibiza cishe ama-ruble angama-220-250 ilitha ngalinye. Ayibilisi kufikela ku-+260°C. Ibekezelela amazinga okushisa angemahle kahle, okungenani ingena ezingeni. Kodwa-ke, ayiqukethe ekubunjweni kwayo izingxenye ezengeziwe ezimelana nokumuncwa kwamanzi emvelweni. Idinga ukushintshwa okuphoqelekile ngemuva kweminyaka emi-2, kungakhathaliseki ukuthi ukusetshenziswa kwemoto kunamandla kangakanani. Iphelele kumamodeli akudala e-VAZ, izimoto zakwamanye amazwe eziphelelwe yisikhathi noma ezinye izimoto ezinamabhuleki ezigubhu. Ingasetshenziswa nasezimotweni ezintsha, kodwa kubalulekile ukulandela isimiso sokushintshwa.
- I-Syntec Super DOT4. Enye inketho eshibhile. Izindleko zingama-ruble angama-300 ilitha ngalinye. Ngeke ibilise kufika ku-+1°C, ngeke iqhwa ifike ku-260°C. Kuyafiseleka futhi ukuvuselela lolu ketshezi ohlelweni ngokuphelele ngemva kweminyaka engu-40 yokusetshenziswa. Yazibonakalisa kahle kuma-VAZ amadala, njengeGranta nePriora.
- I-TRW Brake Fluid DOT Uketshezi oluvela kumkhiqizi owaziwayo wezinto ezibizayo nezisezingeni eliphezulu zokumiswa kanye nezinhlelo zokubhuleka. Izindleko ziphakathi kwama-ruble angama-400-500 ilitha ngalinye. Inezibuyekezo ezinhle ku-inthanethi ezivela kubanikazi bezimoto.
- I-Bosch DOT4. Umkhiqizi akadingi ukukhangisa. Intengo 1 litre cishe ruble 500. Naphezu kwezici ezimenyezelwe eziphansi (iphuzu elibilisayo liyi-230 ° C kuphela, okungukuthi, ezingeni eliphansi elivumelekile), lihlukaniswa ngekhwalithi yalo ezinzile. Abashayeli bezimoto bayaqaphela ukuthi ngisho nangemva kweminyaka engu-3 yokusebenza, lapho behlola uketshezi ukuthi lungakanani amanzi, umhloli akalubhali ngaso sonke isikhathi njengolungenakusebenziseka ngokuphelele, kodwa uncoma kuphela ukushintshwa.
- I-Pentosin Super DOT 4 plus. Uketshezi olunezici ezithuthukisiwe zezinga lokushisa eliphansi neliphezulu. Ifanele ukusetshenziswa ezimotweni zakwamanye amazwe ezinama-disc brakes. Esimeni "esomile", ngeke ibilise ize ifinyelele +260°C.
- I-Oil-Synthesis FELIX DOT4. Umkhiqizo wasekhaya osuka esigabeni senani esimaphakathi. Izibonakalisile ezimotweni zasekhaya nasezimotweni zakwamanye amazwe. Isetshenziswa ngempumelelo ezinhlelweni zamabhuleki zezimoto zaseJapan, njengeMitsubishi Lancer 9 ne-Honda Accord 7. Ngokwemiphumela yokuhlolwa okuzimele, uketshezi lwe-FELIX DOT4 luqinisekise ngokugcwele izici ezimenyezelwe umenzi.
- I-Castrol Brake Fluid DOT I-Liquid ene-fluidity ephezulu yezinga lokushisa eliphansi kanye nokumelana okuhle nokubilayo. Kubiza isilinganiso sama-ruble angama-600-700 ilitha ngalinye. I-brand kuleli cala izikhulumela ngokwayo. Inezibuyekezo ezinhle kuphela ku-inthanethi.
- I-VAG DOT 4. Uketshezi olunophawu lwezimoto zokukhathazeka kwe-VAG. Ngaphezu kwentengo (cishe ama-ruble angu-800 ilitha ngalinye), ayinakho ukushiyeka.
Lapho ukhetha i-brake fluid, kufanele uqondiswe yimithetho eminingana. Okokuqala, ungathengi uketshezi lwemikhiqizo engaqondakali, ikakhulukazi lezo ezishibhile ngokusobala ukwedlula ngisho nenani elincane lenani lomkhiqizo elivela kubakhiqizi abaningi abahlonishwayo. Okwesibili, zama ukuthola ukuthi yiluphi uketshezi olutuswa umenzi wezimoto. Imvamisa lokhu kumane nje kuwukugqama emphakathini. Kodwa-ke, uma uketshezi oluthile lutuswa ngumkhiqizi wemoto, khona-ke luzohambisana no-100% nesistimu yakho yamabhuleki.
Futhi okubaluleke kakhulu: ungakhohlwa ukushintsha uketshezi lwamabhuleki kungakapheli iminyaka emi-3 yokusebenza. Ngisho nezinketho ezibizayo emva kweminyaka emi-3 zizoqongelela inani eliyingozi lamanzi kumthamo wazo, okungaholela ekubilisweni okungazelelwe koketshezi ohlelweni kanye nokwehluleka okuphelele noma okuyingxenye kwamabhuleki.
