Model: A10VO63
Application: Specifically designed for excavator hydraulic systems as a piston pump. It is part of the Rexroth product line and plays a crucial role in powering the various hydraulic functions of an excavator.
Performance Specifications
Displacement
The displacement of the A10VO63 pump is 63 cm³/rev. This means that for each revolution of the pump shaft, 63 cubic centimeters of hydraulic fluid is displaced. This value directly impacts the flow rate of the hydraulic system it serves.
Pressure
Rated Pressure: The pump has a rated pressure of around 280 bar. This is the pressure at which the pump is designed to operate efficiently and reliably during normal working conditions in an excavator's hydraulic circuit.
Peak Pressure: It can handle a peak pressure of up to 350 bar. The peak pressure capacity is important for withstanding sudden pressure surges that may occur during heavy - duty operations such as when the excavator is digging through tough materials.
Speed
Maximum Rotational Speed: The maximum rotational speed of the pump at maximum displacement is approximately 2200 rpm. This speed limit is set to ensure the pump's mechanical integrity and to prevent over - speeding - related issues like excessive wear and reduced efficiency.
Minimum Rotational Speed: There is a minimum rotational speed, usually around 500 - 800 rpm, below which the pump may not function optimally. At very low speeds, the pump might not be able to generate sufficient pressure or flow rate for the excavator's hydraulic functions.
