Frequently Asked Questions
Product Overview & Features
Q: What is the Rexroth A2FO56 series?
A: The A2FO56 is a series of fixed displacement axial piston pumps with a swash plate design (specifically, a "bent-axis" design with a conical piston rotor assembly) intended for use in open circuit hydrostatic drives. They are suitable for both mobile and stationary appliions.
Q: What are the key features of the A2FO56 pump?
A: Key features include:
- High Power Density: Provides substantial power output relative to its size
- Compact Design and Small Dimensions: Saves space in equipment design
- High Overall Efficiency: Contributes to energy savings
- Robust Bearing Design: The drive shaft bearing is designed to meet the service life requirements of demanding appliions
- One-Piece Piston with Piston Ring Seal: Contributes to reliable performance
- Economic Design: Offers a cost-effective solution
Technical Specifiions & Models
Q: What are the key technical parameters for the A2FO56 series?
A: Primary specifiions for the A2FO56 include:
- Geometric Displacement per Revolution: 56.1 cm³/rev
- Rated Pressure: 35 MPa (350 bar)
- Peak Pressure: 40 MPa (400 bar)
- Speed Range: Approximately 500 to 3500 rpm (dependent on specific model and pressure)
- Flow Rate: Proportional to drive speed and displacement; approximately 112 L/min at nominal speed (e.g., 2000 rpm) and Δp=350 bar
- Mass: Approximately 18 kg
Q: How is the A2FO56 model number structured? Can you provide examples?
A: The model code contains information about size, shaft design, port configuration, and control options. Examples of specific models within the A2FO56 series include:
- A2FO56/61L-PPB05
- A2FO56/61R-PPB05-S
- A2FO56/61R-NPB05
- A2FO56/61L-VBB05
(Note: Components like /61L, /61R, -PPB05, -NPB05 indie specific design variations such as rotation direction, porting, and control features)
Maintenance & Servicing
Q: What routine maintenance does the A2FO56 pump require?
A: Proper maintenance is crucial for longevity and reliable operation. Key practices include:
- Pre-Startup Check: Verify oil level in the tank before startup. Use the recommended grade of hydraulic fluid
- Initial Run: After a shutdown of more than 4 hours, allow the pump to run without load for at least 5 minutes before applying pressure
- Regular Monitoring: Consistently check operating parameters like pressure, speed, and, importantly, oil temperature during work. The optimal operating oil temperature is typically suggested to be between 35°C and 60°C. If a sudden temperature rise occurs, investigate the cause immediately
- Inspection: Regularly check pipe joints and flange connections for tightness to prevent leaks and air ingress
- Oil Cleanliness: Maintain the cleanliness of the hydraulic oil. The higher the oil cleanliness, the longer the service life of the pump. External contaminants must be prevented from entering the reservoir and the pump
Q: What should I do if the pump's flow rate is insufficient or performance drops?
A: Potential causes based on common issues include:
- Low Drive Speed: Ensure the motor meets the pump's required rated speed
- Leaks in the System: Check the system for and repair any leakage points
- Aeration/Suction Problems: Inspect the suction line for air leaks. Ensure the oil level in the tank is not too low
- Loose Pump Casing Bolts: Prolonged operation and vibration can loosen bolts, which may need tightening to specifiion
