FAQ:

1. 产品概述与特点 (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 applications .

• 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 applications.

▪ One-Piece Piston with Piston Ring Seal: Contributes to reliable performance.

▪ Economic Design: Offers a cost-effective solution.

2. 技术规格与型号 (Technical Specifications & Models)

• Q: What are the key technical parameters for the A2FO56 series?

◦ A: Primary specifications 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 indicate specific design variations such as rotation direction, porting, and control features).

3. 维护与保养 (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 .
