Bulɔgutigi ka tɔni bɛ a yɛrɛ jira tigitigi ka ɲɛsin bolifɛn ɲɛminɛlan degun hakɛ ni a jibɔ ɲinini ma. I n'a fo:
Bulɔgu hakɛ fitininw ni-minnu ka dɔgɔ walima minnu bɛ bɛn tɔni 20 ma): A ka c’a la, aw bɛ bolifɛn dɔ sugandi min ka tansiyɔn hakɛ ye 10-20mpa ye ani a jibɔ hakɛ ye 40-100L/min ye, i n’a fɔ ZT seriyali hydraulic directional valve (flow rate of 40-100l/min, tansiyɔn ka dɔgɔn walima 25mpa).
Large bulldozers (>20 tɔni): A ka kan ka bɛn ni fɛnsɛbɛnniw ye minnu ka bon, i n’a fɔ frein valve min bɛ kɛ ni sofa fanga 520 ye, ni a jibɔ hakɛ ye 246L/min ye ani tansiyɔn ye 2,69MPa ye, a bɛ don a yɛrɛ la ni a yɛrɛ ye{{4}Locking valve ka se ka doni girinmanw ni dugukolo gɛlɛnw kunbɛn.
Seko ni dɔnko : Aw ye motɛri flɛri fanga lajɛ (i n’a fɔ 447kW Caterpillar D10T2) walasa ka a dɔn ko bolifɛn ɲɛminɛlan bɛ se ka jibolisira bɛɛ ka tansiyɔn kuncɛ.
Modèle structure compatibilité .
Danfaraba bɛ bolifɛn ɲɛminɛcogo la modeli suguya caman cɛ. I n'a fo:
Crawler Bulldozer: A ka kan ka bolifɛn ɲɛminɛlan dɔ sugandi min bɛ sira teliya danfara kunkanko dɛmɛ, i n’a fɔ 16Y-76-22000 Steering Valve min dabɔra kɛrɛnkɛrɛnnenya la SD16 bulonw kama, min bɛ se ka jɛ ni freinw ka juru ye walasa ka se ka bolifɛn tigitigi sɔrɔ.
Bulldozer min bɛ kɛ ni wotoro ye: Aw bɛ jateminɛ kɛ ka flow amplification valve (i n’a fɔ VSFA suguya) fara ɲɔgɔn kan ni ɲɛminɛlan ye walasa ka manɛwɛrɛya sabati ka tɛmɛn amplification proportional principe fɛ.

Aw bɛ se ka aw yɛrɛ dege baarakɛyɔrɔ ni baarakɛcogo la .
dugukolo ni doni cogoyaw .
Dugukolo gɛlɛnw (minw, kuluw): Fɔlɔ ka kan ka di bolifɛnw ma minnu bɛ ni tansiyɔn musaka baara ye, i n’a fɔ farankanw ni lakanalanw faralen ɲɔgɔn kan, minnu bɛ se ka degunw lajɔ a yɛrɛma ni sira bɛ siri (a ka c’a la, degun dakun ye 10-30mpa ye) walasa ka ji yɔrɔw tiɲɛni bali.
Loavy load bulldozer: A ka kan ka valve farikolo fɛnw sugandi minnu bɛ se ka u yɛrɛ tanga kosɛbɛ (i n’a fɔ sanfɛ-Nɛgɛ walima nɛgɛ barikama), ani ka a lajɛ ko valve core sɛgɛn bɛ se ka sɛgɛn. Misali la, valve cores minnu datugulen don ni tungsten carbide ye, olu bɛ se ka doni girinmanw baara minnu bɛ kɛ tuma caman na, olu sɛgɛn.
Lamini lakanani jugumanba .
Funteni hakɛ min bɛ se ka funteni kunbɛn (i n’a fɔ silicon carbide seramiki valve bloc minnu bɛ se ka funteni muɲu fo ka se degere 1600 ma ) walima siratigɛ la ni funteni hakɛ jateminɛ musaka ye walasa ka valve jaming bali min bɛ sɔrɔ funteni bonya ni a sɔgɔli fɛ.
Bugun/lamini min bɛ kɛ ni bɔgɔ ye: Duplex inox (i n’a fɔ 2205) walima hastelloy valve body ta, ni O-ring sealing (i n’a fɔ fluorororubber viton) walasa ka buguri doncogo ni a sɔgɔli cɛmancɛ bali .

Flow ani pressure matching .
Flow jatebɔ : ka da bolifɛn teliya kan (i n’a fɔ piston rod lamaga teliya 50mm/s) ani silinda cɛmancɛ (i n’a fɔ φ 125mm), ka jibɔ hakɛ wajibiyalen jateminɛ (q=π× 2 × V) walasa ka a dɔn ko bolifɛn bolicogo hakɛ min bɛ se ka kɛ (i n’a fɔ 120l/min) o bɛ bɛn.
Tansiyɔn hakɛ : Bololabaarakɛla ka tansiyɔn hakɛ jateminɛlen ka kan ka caya ka tɛmɛ sigida ka tansiyɔnba kan (a ka c’a la, baarakɛ tansiyɔn siɲɛ 1,2-1,5). Misali la, ni baarakɛ tansiyɔn ye 15MPa ye, valve min ka tansiyɔn hakɛ bɛ se 20MPa ma, o ka kan ka sugandi.
Tuluw ka baarakɛcogo .
Aw bɛ ji tulu suguya (i n’a fɔ tulu minɛta, tulu dilannen) ani a sɔgɔli hakɛ (i n’a fɔ ISO VG 46) dafa min bɛnnen don bolifɛn ɲɛminɛlan ma walasa a kana kɔrɔya walima valve core jamming min bɛ sɔrɔ tulu tɛ se ka kɛ cogo min na.

Baarakɛcogo ni baarakɛcogo wajibiyalenw .
Kɔlɔsili tiɲɛni ni jaabi teliya .
Valve Core ka sensitivity: Aw bɛ bolifɛn dɔ sugandi min bɛ ni proportionnel contrôle walima électronique control ye (i n’a fɔ BPBS hydraulique steering gear+VSFA flow amplification valve) walasa ka "small angle fine adjustment" ani teliya jaabi sɔrɔ, ka baarakɛcogo ɲuman ɲɛ.
Seginkanni dannaya : A ka kan ka segin-ka-bɔ-sɔgɔli gɛlɛya lajɛ ani dakunw cogoya ɲuman walasa ka a dɔn ko sumanw kɔnɔna bɛ segin teliya la cɛmancɛ la bolifɛn ɲɛminɛbaga bɔlen kɔfɛ, ka i yɛrɛ tanga jiginni ma.
Lakanali ni baarakɛbaliya dilancogo .
Yɛrɛ datugucogo ani antioperation: misali la, 520 so fanga bulldozer ka bolifɛn bɛ self-Locking valve dɔ fara ɲɔgɔn kan. Ni a daminɛna, a bolokɔni ka kan ka segin a jɔyɔrɔ fɔlɔ la walasa ka kasaara bali min bɛ sɔrɔ baarakɛcogo jugu fɛ.
Sisitɛmu redundant: Ni dannayaba bɛ yen i n’a fɔ minɛnw, bolifɛn minnu tɛ ni solenoid valves ye, olu bɛ se ka sugandi. Ni valve principal ma se, a bɛ wuli a yɛrɛma ka taa backup circuit la, ka dɔ bɔ downtime la.
