Pump Type: Hydraulic Main Piston Pump
2. Performance Parameters
Displacement
Nominal displacement: [X] cc/rev. This value determines the volume of hydraulic fluid the pump can deliver per revolution, which is crucial for powering the various hydraulic functions of the excavator such as the boom, arm, and bucket movements.
Pressure Ratings
Rated pressure: [X] MPa (megapascals). This is the normal operating pressure at which the pump is designed to work continuously and efficiently.
Maximum pressure: [X] MPa. The pump can withstand this peak pressure for short - term operations, ensuring reliable performance during sudden load changes.
Speed Range
Recommended operating speed: [X] - [Y] rpm (revolutions per minute). Operating within this speed range helps to maintain the pump's efficiency and longevity.
Maximum speed: [Z] rpm. Exceeding this speed may cause excessive wear and potential damage to the pump.
Flow Rate
At the rated speed and displacement, the flow rate is approximately [calculate based on displacement and speed, e.g., displacement (cc/rev) × rated speed (rev/min) / 1000 = L/min] L/min. This flow rate is essential for providing the necessary power to the hydraulic cylinders and motors in the excavator.
