1. What is the core design and application scope of the A10VNO series pumps?
The A10VNO series is a à haute pression, pompe à cylindrée variable à pistons axiaux engineered for heavy-duty hydraulic systems. It is widely applied in:
- Engins de chantier (excavatrices, grues, chargeurs)
- Machines industrielles (presses hydrauliques, machines de moulage par injection)
- Équipement minier (perceuses à roche, systèmes de convoyeurs)
- Systèmes marins (deck machinery, systèmes de direction)
- Machines agricoles (gros tracteurs, moissonneuses)
- Energy equipment (wind turbine hydraulic control systems)
Models A10VNO45DR/52R-VSC11N00 and A10VNO85DRS/53L-VWC12N00 are optimized for high-pressure, high-flow scenarios requiring precise control and reliable performance under extreme working conditions.
2. How to interpret the model designations of the two pumps?
Répartition des composants clés du modèle pour plus de clarté:
- A10VNO: Identifiant de la série (Pompe à cylindrée variable à pistons axiaux, high-pressure grade)
- 45/85: Déplacement nominal (45 CM³ / Rev / 85 CM³ / Rev)
- DR/DRS: Type de contrôle (DR = Pressure Compensated Control; DRS = Dual Control [Pression + Flow Compensated])
- 52R/53L: Mounting flange code (52R = SAE B flange; 53L = SAE C flange, pour ISO 3019-2)
- VSC11N00/VWC12N00: Configuration code (includes seal type, pressure relief setting, and electrical interface)
3.What are the core features of the A10VNO series pumps?
- High-Pressure Resistance: Robust cylinder block, piston, and valve plate design withstands extreme pressures (jusqu'à 40 MPA), ensuring durability in heavy-duty applications.
- Variable Displacement Efficiency: Automatically adjusts displacement based on system demand (via DR/DRS control), minimizing energy consumption and reducing fuel costs.
- Precision Control Performance: Pressure/flow compensation systems provide stable output with minimal fluctuation, improving the accuracy of hydraulic actuators (par ex., cylindres, moteurs).
- Fonctionnement à faible bruit: Optimized flow path design and hydraulic balance structure reduce operating noise (≤ 78 dB at 2500 RPM), suitable for both indoor and outdoor use.
- Long Service Life: Hardened steel components (nitrided piston rods, chrome-plated shafts) and anti-wear coatings reduce friction; self-lubricating design extends maintenance intervals.
- Leak-Proof & Corrosion-Resistant: High-temperature resistant Viton seals and aluminum alloy housing (with anti-corrosion treatment) prevent oil leakage and rust.
