Displacement:
The A11VO95 pump has a displacement of 95 cc/rev, indicating the volume of fluid it can move per revolution.
This displacement is well-suited for medium to large-sized excavators, providing the necessary power for hydraulic functions.
Pressure Rating:
Operating at high pressure, the pump can handle demanding tasks. The pressure rating is a critical specification, and in the case of the A11VO95, it often operates at pressures up to 450 bar, ensuring robust performance in challenging excavation conditions.
Control Options:
This pump offers various control options, including the common swashplate design. The swashplate angle determines the pump's output flow, allowing for precise control of hydraulic functions in excavators.
Efficiency:
The A11VO95 is designed for high efficiency, contributing to overall fuel efficiency in hydraulic systems. Efficient pumps reduce energy consumption and heat generation, extending the lifespan of the hydraulic system.
Repair and Parts:
When it comes to excavator repair involving the Rexroth A11VO95 hydraulic piston pump, it's crucial to have a comprehensive understanding of its internal components. Some key parts involved in the repair process include:
Piston Assembly:
The piston assembly is a critical component responsible for pressurizing the hydraulic fluid.
Over time, pistons may wear or develop issues, requiring replacement during the repair process.
Cylinder Block:
The cylinder block houses the pistons and is subject to wear due to constant movement. During repair, inspection and potential replacement of the cylinder block may be necessary to maintain optimal performance.
Valve Plate:
The valve plate controls the flow of hydraulic fluid. Damage or wear to the valve plate can lead to inefficiencies and loss of performance. Replacement or refurbishment of the valve plate is a common repair task.
Swashplate Mechanism:
The swashplate mechanism controls the angle of the swashplate, determining the pump's output. During repair, the swashplate assembly may be inspected and adjusted to ensure proper functionality.
Bearings and Seals:
Bearings and seals play a crucial role in preventing leaks and ensuring smooth operation. Inspecting and replacing worn bearings and seals is a routine part of the repair process.
