Frequently Asked Questions
What is the A10VSO71 pump?
The A10VSO71 is an axial piston variable displacement pump manufactured by Bosch Rexroth. It operates via a swashplate design, allowing adjustable flow rates by changing the swashplate angle. This pump is widely used in high-pressure hydraulic systems for industrial machinery, construction equipment, and marine applications due to its efficiency, compact structure, and pressure adaptability.
What are the key technical specifications?
- Displacement (Vg max): 71 cm³/rev
- Nominal Pressure (p nom): 280 bar
- Maximum Pressure (p max): 350 bar
- Speed Range: Up to 2,200 rpm (at Vg max)
- Flow Rate (at nominal speed): 156 L/min
- Weight: ~33 kg (standard model)
- Control Options: Pressure cutoff (DR type), load sensing, or proportional control variants
How does the "pressure cutoff" function work?
The A10VSO71DR variant features a pressure cutoff (DR control) mechanism. When system pressure reaches the preset cutoff value, the pump reduces its displacement to maintain constant pressure, minimizing energy consumption. The swashplate adjusts dynamically based on flow demand while sustaining pressure.
What are common applications?
This pump is ideal for:
- Hydraulic presses and injection molding machines
- Construction machinery (e.g., excavators, cranes)
- Marine and offshore systems
- Industrial hydraulic power units
How to troubleshoot performance issues?
- Low Flow/Output: Check for clogged filters, worn seals, or incorrect control settings
- Overheating: Verify fluid viscosity, cooling system, or excessive pressure settings
- Noise/Vibration: Inspect for cavitation, air ingress, or misalignment
