Large bulldozers (>20 tons): Specification sang zawk, 520 horsepower bulldozer-a hman thin steering brake valve ang chi, flow rate 246L/min leh pressure 2.69mpa, self-locking valve nena inzawm, load rit tak tak leh complex terrain te nena inzawm theih ang chi te nen inmil a ngai a ni.
Power Matching: steering valve hian hydraulic system pumpui peak pressure a tuar thei tih chian nan engine flywheel power (Caterpillar D10T2 tan 447kW ang chi) en rawh.
Model structure nena inmil .
Model hrang hrang zingah steering system design-ah hian danglamna lian tak a awm a. Entir nan:
Crawler Bulldozer: Track speed difference control support thei tur steering valve thlan a ngai a, chu chu SD16 bulldozer atana siam bik 16Y-76-22000 steering valve a ni a, chu chu brake clutch nen inzawm thei a, steering dik tak a thlen theih nan.
Wheeled Bulldozer: Proportional amplification principle hmanga maneuverability tihchak nan flow amplification valve (VSFA type ang chi) chu steering gear nen pairing ngaihtuah rawh.
Hnathawh dan leh hnathawh dan tur nena inmil .
Terrain leh load dinhmun .
Complex terrains (mines, mountains): Pressure compensation function nei steering valve te chu priority pek tur a ni a, chu chu combination valve te chu integrated safety valve nei te an ni a, chu chuan track a stuck chuan pressure a ti relieve thei a (pressure threshold hi 10-30mpa a ni tlangpui) a, chu chuan hydraulic components a tichhia lo ang.
Heavy Load Bulldozer: Impact resistance chak tak nei valve body materials thlan a ngai a (high-Strength cast iron emaw steel ang chi), valve core-a wear resistance a awm theih nan. Entirnan, tungsten carbide hmanga khuh valve core te hian load rit tak tak an tih fo thinte chu an tuar thei a ni.
Environment humhalh nasa lutuk .
High/low Temperature Environment: Temperature resistant materials (silicon carbide ceramic valve blocks ang chi, temperature 1600℃thlenga tuar thei ang chi ) emaw, thermal expansion leh contraction avanga valve jamming awm lohna tura temperature control compensation nei directional valve emaw thlang rawh.
High dust/corrosive environment: duplex stainless steel (2205 ang chi) emaw hastelloy valve body emaw hman a ni a, O-ring sealing (fluorubber viton ang chi) hmangin leivut lut leh medium corrosion a awm loh nan
Hydraulic System Parameter inmil tur a ni.
Flow leh pressure matching .
Flow Calculation: Steering cylinder hnathawh speed (piston rod movement speed 50mm/s ang chi) leh cylinder diameter (Φ 125mm ang chi) atanga chhut chuan, steering valve-a flow rate sang ber (Such 120L/min) chu a tlin theih nan flow rate mamawh (Q{{2}π× R 2 × V) chu chhut la.
Pressure Rating: Steering valve-a rated pressure chu system-a peak pressure aiin a sang zawk tur a ni (a tlangpuiin working pressure aiin 1.2-1.5 in a sang zawk). Entirnan, working pressure chu 15mpa a nih chuan valve rated pressure 20mpa nei chu thlan tur a ni.
Oil nena inmil .
Steering valve atana tha hydraulic oil chi (mineral oil, synthetic oil ang chi) leh viscosity range (ISO VG 46 ang chi) te chu oil incompatibility avanga seal emaw valve core jamming emaw a awm loh nan confirm rawh.
Performance leh functional mamawh .
Control dikna leh chhanna speed .
Sensitivity of Valve Core: "Small angle fine adjustment" leh fast response neih theihna turin steering valve proportional control emaw electronic control function nei (BPBS hydraulic steering gear+VSFA flow amplification valve ang chi) thlang la, operational efficiency pawh a tha ang.
Return Reliability: Return spring a nghet leh awm loh leh sealing components quality te enfiah a ngai a, chu chuan valve core chu steering rod a chhuah hnuah rang takin center-ah a kir leh thei ang a, deviation a awm loh nan.
Security leh redundancy design 1000 a awm bawk.
Self locking leh anti misoperation: Entirnan, 520 horsepower bulldozer-a steering brake valve hian self-locking valve a inzawm khawm a. A tan dawn chuan handle chu misoperation avanga accident awm loh nan a awmna hmunah dah kir leh a ngai a ni.
Redundant System: Reliability sang tak nei scenario-ah chuan mines ang chi, redundant steering valve backup solenoid valve nei te chu thlan theih a ni. Main valve a fail chuan backup circuit ah a inthlak nghal a, downtime a ti tlem a ni.
