Features:
1. Low noise level for improved operational environment.
Technical data:
Specifications:
Applications:
1. In large hydraulic excavators, this axial piston pump delivers 280 bar continuous pressure to power boom and bucket cylinders. Its load-sensing control dynamically adjusts flow based on joystick inputs, while the through-drive integrates gear pumps for pilot control, improving coordinated movements and reducing energy consumption by 15%.
2. When powering concrete pump truck booms, the hydraulic pump's rapid response (<50ms) enables precise multi-section boom deployment. Modular design allows quick component replacement, while optimized suction lines prevent cavitation during high-altitude operations, ensuring reliable continuous pouring.
3. For combine harvester header lifting systems, the piston pump's dual drain ports effectively manage case pressure. Combined with proportional valves, it achieves millimeter-level height adjustment. High power density saves space while ensuring durability in rough field conditions.
4. When powering tractor hydraulic hitches, the axial piston pump's flow-pressure compound control adapts to various implements. Low noise (<75dB(A)) improves operator comfort, while hardened surfaces extend service life beyond 10,000 hours, reducing maintenance.
Competitive Advantage:
1. Wide viscosity range (15-1000cSt) and temperature tolerance (-25℃~80℃) ensure reliable marine deck operations in arctic and tropical conditions.
2. Modular design enables 60% faster maintenance through interchangeable DR/DFR/ED controls, with 85% component commonality in industrial power units.
3. <75dB noise emission meets ISO 4412 standards for port cranes in noise-sensitive areas, minimizing acoustic pollution.
4. DFLR constant power control auto-balances hydraulic output for wind turbine pitch systems, achieving 0.3sec blade adjustment during wind gusts to boost energy yield 15%.
5. 100% through drive capability allows tandem auxiliary pump installation, delivering 210L/min main flow with auxiliary lubrication, increasing power density 40% over conventional designs.
The Analysis For Rexroth A10V(S)O Axial Piston Pump Common Breakdown:
1. Abnormal Noise: Laser align couplings if radial deviation >0.05mm. Replace SKF 6316-C3 bearings when clearance >0.1mm, lubricate with NLGI 2 grease.
2. Oil Leakage: Replace cracked V-seals with FKM material if service life <5000h. Laser cladding required for >0.3mm sand holes on port plate, polished to Ra0.4μm.
3. Motor Overload: Check relief valve setting if backpressure >12MPa. Clear >15μm contaminants causing piston seizure and 30% torque spike.
4. Variable Failure: Ultrasonic clean control circuits if diameter <4mm. Replace EPDM seals when O-ring hardness exceeds 90 Shore A.
5. Suction Deficiency: Upgrade to DN40 pipes if flow velocity >4m/s in DN25 lines. Install booster pump at vacuum >0.08MPa.
