Competitive Advantages
1. Adopts load sensing + constant power combined control, automatically matches flow according to load changes, effectively reduces fuel consumption and system heat, outstanding energy-saving performance.
2. Integrated design with built-in charge pump and relief valve, compact flywheel housing mounting structure, fewer connecting pipelines, convenient installation and maintenance for mobile machinery.
3. High-strength friction pairs and optimized flow pulsation structure, stable output under 350bar long-term working pressure, strong overload resistance and long service life.
The Analysis for Rexroth A8VO Axial Piston Pump Commom Breakdown:
1. Insufficient output flow & weak action: Usually caused by worn cylinder block, valve plate or piston shoes, leading to internal leakage; also related to insufficient charge pump pressure.
2. Abnormal noise and vibration during operation: Main reasons include oil shortage, contaminated hydraulic oil, damaged bearing or loose fit of transmission spline.
3. High system temperature and pressure instability: Generally due to stuck LS control valve, faulty constant power regulator or excessive internal leakage of pump assembly.
