Applications:
1. This axial piston pump achieves <100ms response for excavator arm coordination. DFLR triple-mode control automatically boosts pressure to 280bar during heavy lifting and switches to energy-saving mode under light loads, reducing fuel consumption by 30%.
2. The through drive design of this hydraulic pump allows tandem installation with gear pumps. Main pump delivers 210L/min for slewing motors while auxiliary pump supplies outrigger systems, enabling synchronized 360° rotation and chassis stabilization.
3. Marine-grade piston pump with salt spray resistance operates reliably in 15-1000cSt viscosity range. ED electro-hydraulic control enables remote anchor speed adjustment, handling 30-ton chains at 350bar peak pressure with <75dB noise for IMO compliance.
4. DFLR constant power control in this axial piston pump intelligently balances pressure-flow demands during research vessel crane operations. SAE flanges ensure quick coupling with marine motors when handling 280bar/140cc deep-sea sampling equipment.
Competitive Advantage:
1. DIN 45635-certified shock resistance reduces field machinery failure rates 50% by maintaining hydraulic stability on rough terrain.
2. Integrated ED electro-hydraulic module enables CAN bus-controlled multi-pump synchronization, achieving ±0.5mm positioning in 32-point lifting systems.
3. Energy-saving mode automatically minimizes displacement during standby, cutting idle power 70% and saving 12,000kWh annually in industrial systems.
4. 18-140cc displacement range serves diverse applications from micro-injection to 10,000-ton presses, increasing filter press dehydration efficiency 35%.
5. SAE standard flanges reduce oil drilling system integration time 40% through quick-connect hydraulic circuits.
The Analysis For Rexroth A10V(S)O Axial Piston Pump Common Breakdown:
1. Slow Pressure Buildup: Adjust gear backlash <0.15mm in charge pump. Replace check valve springs with >20% force loss. Install automatic vents at system high points.
2. Oil Emulsification: Install centrifugal separators if water content >1000ppm. Replace desiccant in breathers when humidity >60%.
3. Seal Failure: Add water-cooled sleeves if lip temperature >120°C. Use hydraulic press for seal installation with radial runout >0.1mm.
4. Response Lag: Switch to ISO VG32 oil if control oil viscosity >46cSt. Calibrate LVDT sensors when proportional valve response exceeds 500ms.
5. Piston Wear: Install β=75 filters to remove >5μm particles. Apply HVOF coating if plating loss >3% on piston surface.
