Rated Speed: The rated speed of the hydraulic main pump for the VOLVO EC480D excavator is generally in the range of 1500 - 2200 rpm. Operating within this speed range ensures efficient performance and stable operation while minimizing wear and tear on internal components such as pistons, cylinder blocks, and valves. Staying within the rated speed helps maintain the pump's reliability and extends its service life, reducing the need for frequent repairs or replacements.
Maximum Speed: The maximum allowable speed is approximately 2500 rpm. Continuous operation at the maximum speed can lead to increased wear and a reduced lifespan of the pump. It is advisable to keep the pump's operation within the rated speed range to avoid potential damage to the pump and the overall hydraulic system, ensuring long-term functionality and performance of the excavator.
Pump Type
This is an axial piston pump. The axial piston design is commonly used in excavator hydraulic systems due to its high efficiency, excellent pressure-handling capabilities, and precise control over the hydraulic fluid flow. It allows for efficient conversion of mechanical energy from the engine into hydraulic energy, making it suitable for the demanding requirements of the VOLVO EC480D excavator. The pump may feature a variable displacement mechanism, which enables it to adjust the flow rate according to the needs of the excavator's operations, optimizing energy consumption and performance.
