Displacement: It may be around 30 - 50 mL/r. The specific value needs to be determined according to the actual design and the working requirements of the dump truck to meet the flow requirements of the steering and lifting systems.
Rated speed: Generally, it is in the range of 1500 - 2000 r/min. This is a common working speed range for hydraulic pumps, which can be well matched with the output speed of the vehicle engine to ensure the stable operation and efficient working of the pump.
Rated pressure: Approximately between 16 - 25 MPa. This pressure range is sufficient to provide the power required for the steering and lifting actions of the dump truck, ensuring that the vehicle can operate normally under various working conditions.
Theoretical flow rate: Calculated based on the displacement and rated speed, it may be between 45 - 100 L/min. The size of the flow rate directly affects the sensitivity of the steering and the speed of the lifting.
