Xoolaatal parametru core bi ci bulldozers
Tonnage ak adaptaasioŋ kuuraŋ
Tonnage bu benn bulldozer dafay wane ni pression ak debit bi vanne bi di doxee. Ci misaal:
Buldozers yu ndaw ak digg (0} buldozers (Less bu ëpp wala tollu ci 20 ton): Dafay faral di tann benn valve vertering ak 10-20MPa 10-20L/min 40-100L/min, lu melni valve hydraulique hydraulique (40-100L/min) 25MPa).
Large bulldozers (>20 ton): fàww ñu méngoo ak ay leeral yu gëna kawe, lu melni vanne frein frake bi ñuy jëfandikoo ci bulldozer bu am 520 fas, ak 246L/min ak pression bu 2.69MPa, boole ci boppam- valve ngir mëna jànkoonte ak sargal yu diis ak terain yu bari.
Jokkoo ak doole: Xoolal dooley fleel motër (lu melni 447kW ngir Caterpillar D10T2) ngir mëna wax ni vanne de steering bi mën na dékku pression bi gëna kawe ci sistem hydraulique bi yépp.
Taxawal structurel model
Amna ay wuute yu am solo ci jëmmal sistem steering yi ci biir model yu wuute yi. Ci misaal:
Crawler bulldozer: Dafay am solo ñu tànn benn vanne buy jàppale ci wàllu gaawaay, lu ci melni 16Y-76-20000 vanne buy yeete ci SD16 bulldozers, mën nañu ko boole ak frein frein ngir mëna am dekkuwaay bu leer.
Buldozer bu àll bi: Xalaatal boole benn vanne amplification buy jaar (lu melni xeetu VSFA) ak benn vitesse ngir gëna mëna jëfandikoo ci njàngale mi ci wàllu amplification bu méngoo.

Déggoo ci barabu liggéey bi ak anam yi ñuy liggéeyee
Terrain ak charge
Emplex yi (mine, tund yi): Dañu wara jox priority ngir mëna def ay vanne ak fonction de compensation pression, lu melni vanne vanne yu boole ak vanne kaaraange yuñ boole, te loolu mën na wàññi presion su tëju (ci threshold bi dafay faral di am 10-30MPa) ngir moytu yàqu-yàqu ci komponent hydraulique yi.
Buldozer bu am doole: Dafay am solo lool ñu tànn macceer vanne yu am doole yu am doole (lu melni {0} yu kawe-strongth fer wala asiye), ak fexe ba responsabilité sole bi ci core vanne bi. Ci misaal, core vanne yi ñu boole ak carbide tungsten mën nañu muñ ràndewu yu bari yu bari.
aar environmaa bi
Tàngoor wu tàng/lu suuf: Tannal tàngoor wi ci tàngoor (lu melni bloke valve valve ceramic silicon yi mëna dékku tàngoor wu yegg ba 1600 degre) wala vanne de contrôle yu am tàngoor ngir moytu jamming valve bi juddoo ci yaatuwaay ak contraction.
Këru pënd bu kawe/corrosif: Diggu asiye duplex bu dëgër (lu melni 2205) wala yaram vanne valve Hastelloy, ak O{1}} ràbbal (lu melni fluorurubber VITON) ngir moytu pënd ak corrosion bu digg bi

Taxawal parametre sistem hydraulique
Flow ak pression pression
Xayma: Ci gaawaayu liggéey bu silindre steeer (lu melni piston bi gaawaayu mouvement 50mm/s) ak diametre silindre (lu melni φ 125mm), xayma ni debit bi war (Q{{2}ϗ × v) ngir mëna wax ni tolluwaayu debit bi gëna mag ci valve de vent laaj.
Li ñuy woowe pressure: Pression biñ jox vanne steering bi dafa wara gëna kawe pression bi ci sistem bi (dafay faral di 1.2-1.5 yoon pression biy liggéey). Ci misaal, sudee pression bi ñuy liggéey mooy 15MPa, dañu wara tànn vanne bu am pression bu am 20MPa.
mbëjtewoo
Xaarandil xeetu diwu hydraulique (lu melni diwu mineral, diwu synthetik) ak viskosite (lu melni ISO VG 46) bu méngoo ak vanne sètering ngir moytu màgget wala vanne vanne buy bawoo ci ñàkka mëna tàkk.

Performance ak li ñuy laaj ci liggéey
Kontrôle njubte ak tontub tontu
Xamme core vanne: Tannal benn vanne bu dëgër ak fonction de contrôle wala fonction de contrôle elektronik (lu melni BPBS hydraulique hydraulique vanne valve de débit) ngir mëna am "gëna gaaw bu ndaw" ak tontu bu gaaw, gëna mëna jëfandikoo.
Wutalug dellu ginaaw: Dafay am solo lool ñu xool stiffness ressort biy dellusi ak kalite komponent yi ñuy tëj ngir mëna wax ni core valve bi dafay gaaw dellu ci digg bi ginaaw bi ñu bàyyi batone steering bi, di moytu deviation.
Kaaraange ak defarum redondance
Di tëj boppam ak ñàkka mëna jëfandikoo: Ci misaal, vanne frein u frein bu 520 fas dafay boole boppam- valve. Sooy tàmbali, fàww ñu delloo ci liggéey bi njëkk ngir moytu musiba yi bawoo ci njuumte.
Sistemu rendant: Ci senaario yi wóor yu bari yu melni mine yi, vanne yu bari yi ak vanne solenoid yi ci ginaaw. Su vanne bu mag bi ñàkkee, dafay soppi ci saasi ci sircuit bi, wàññi démb.
