Usuku lokuphelelwa yisikhathi kwe-brake fluid
Okuqukethwe
Izizathu zokwehla kwekhwalithi
Ukwakhiwa kwe-brake fluid kuhlanganisa i-polyglycols, i-boric acid esters, ne-Dot 5 iqukethe i-poly-organosiloxanes (ama-silicones). Ngaphandle kwalokhu kokugcina, zonke lezi zingxenye ezingenhla ziyi-hygroscopic. Njengomphumela womsebenzi, izinto zithatha amanzi emoyeni. Kamuva, i-hydraulic system ishisa ngokweqile, uketshezi olukumaphedi odonsa amanzi lushisa lufike kuzinga lokushisa lokuhwamuka bese lwakha isikhiya somoya. Ukuhamba nge-brake pedal kuba okungaqondile futhi ukusebenza kahle kwamabhuleki kuyehla. Lapho ifinyelela umswakama ongu-3,5% ngevolumu, i-TF ibhekwa njengendala, futhi ku-5% noma ngaphezulu, ayifaneleki ukusetshenziswa.
Izimfanelo zobuchwepheshe zoketshezi zincike ekushiseni okuzungezile. Uma isimo sezulu sishisa kakhulu, kukhuphuka umswakama, futhi i-TJ izolahlekelwa ngokushesha ukusebenza kwayo.
Ukufaka esikhundleni nini?
Umkhiqizi ubonisa usuku lokukhiqiza, impilo yeshalofu nokusebenza esitsheni. Ukwakheka kwamakhemikhali kuthinta ngqo isikhathi sokusetshenziswa. Isibonelo, i-Dot 4 ihlanganisa, ngaphezu kwama-glycols, ama-esters e-boric acid, abopha ama-molecule amanzi abe yizinkimbinkimbi ze-hydroxo futhi andise impilo yesevisi kuze kufike ezinyangeni ezingu-24. I-lubricant ye-Dot 5 efanayo, ngenxa yesisekelo se-silicone ye-hydrophobic, i-hygroscopic kancane futhi ingagcinwa iminyaka engu-12-14. I-Dot 5.1 ibhekisela ezinhlobonhlobo ze-hygroscopic, ngakho-ke, izithasiselo ezikhethekile ezigcina umswakama zingeniswa kuyo, okwandisa impilo yeshalofu eminyakeni engu-2-3. Uketshezi lwe-hygroscopic kakhulu yi-Dot 3 enempilo yesevisi yezinyanga eziyi-10-12.
Isilinganiso sesikhathi seshelufu se-brake fluid siyizinyanga ezingama-24. Ngakho-ke, kufanele ithathelwe indawo lapho isibonakaliso sokuqala sokuncipha kokusebenza kahle kwesistimu ye-brake noma ngemva kwamakhilomitha ayizinkulungwane ezingu-60.
Usihlola kanjani isimo?
Kungenzeka ukucacisa ikhwalithi ye-lubrication ye-hydraulic usebenzisa umhloli okhethekile. Idivayisi iwumaka ophathwayo onenkomba ebucayi. Umhloli wehliswa ethangini ngenhloko yenkomba, futhi umphumela uboniswa ngendlela yesignali ye-LED ebonisa okuqukethwe komswakama. Ukugcina umbuso wokushisa wokusebenza we-TJ (150-180 ° C), isilinganiso samanzi akufanele sidlule i-3,5% yenani eliphelele.
I-brake fluid ihlala isikhathi esingakanani ephaketheni?
Esitsheni esivaliwe, impahla ayihlangani nomoya futhi igcina izakhiwo zayo zobuchwepheshe. Kodwa-ke, ngokuhamba kwesikhathi, ezinye izinhlanganisela ziwohloka ngokwemvelo. Ngenxa yalokho: iphuzu elibilisayo kanye ne-viscosity yoshintsho lomkhiqizo. Ngokwezindinganiso zamazwe ngamazwe, impilo yeshalofu yoketshezi olukhethekile emaphaketheni angavuliwe, kuhlanganise noketshezi lwamabhuleki, ikhawulelwe ezinyangeni ezingama-24-30.
Izincomo zokusetshenziswa nokugcinwa
Amathiphu alula ukusiza ukwelula impilo yeshalofu ye-TJ:
- Gcina impahla esitsheni esivalwe ngokuvikelekile.
- Umswakama womoya ekamelweni akufanele udlule u-75%.
- Vala isivalo sethangi ngokuqinile futhi ugcine izimbobo zokungenisa umoya zihlanzekile.
- Shintsha uketshezi njalo ngemva kuka-60000 km.
- Buka ukucinana kwamashaneli esistimu yamabhuleki.
Manje uyazi ukuthi i-brake fluid igcinwa isikhathi esingakanani futhi yiziphi izici ezithinta ikhwalithi yayo.
