Without specific product documentation, it's difficult to determine the exact displacement. However, for a hydraulic pump used in an excavator like the JS 8030, the displacement is likely in the range of 50 to 150 cubic centimeters per revolution (cm³/rev). A suitable displacement is crucial for providing the necessary flow to power functions such as boom lifting, arm movement, and bucket operation in the excavator.
Operating Pressure
Rated Pressure: As suggested by the "31" in the model, the rated pressure of this pump is probably around 31 MPa. This is the pressure at which the pump is designed to operate continuously to ensure stable performance in the excavator's hydraulic system.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is typically higher than the rated pressure. It may reach around 37 MPa to 40 MPa. This allows the pump to handle sudden high-load situations that occur during the excavator's operation, like when digging through hard soil or rocks.
