1. What is the core design and application scope of the A10VNO series pumps?
The A10VNO series is a 高圧, アキシアルピストン可変容量ポンプ engineered for heavy-duty hydraulic systems. It is widely applied in:
- 建設機械 (掘削機, クレーン, ローダー)
- 産業機械 (油圧プレス, 射出成形機)
- 鉱山機械 (さく岩機, コンベアシステム)
- 海洋システム (deck machinery, ステアリングシステム)
- 農業機械 (大型トラクター, 収穫者)
- 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?
Breakdown of key model components for clarity:
- A10VNO: シリーズ識別子 (アキシャルピストン可変容量ポンプ, high-pressure grade)
- 45/85: 公称変位 (45 cm³/rev / 85 cm³/rev)
- DR/DRS: 制御タイプ (DR = Pressure Compensated Control; DRS = Dual Control [プレッシャー + Flow Compensated])
- 52R/53L: Mounting flange code (52R = SAE B flange; 53L = SAE C flange, per 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, ピストン, and valve plate design withstands extreme pressures (まで 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 (例えば, シリンダー, モーター).
- 低騒音動作: 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.
