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 .
