The displacement of the hydraulic pump for the Caterpillar 330GC excavator is a key parameter. It is likely to be in the range of 100 - 150 cubic centimeters per revolution (cm³/rev). This displacement value is carefully calculated to meet the hydraulic power requirements of the excavator, which is used for various tasks such as arm extension and retraction, bucket operation, and slewing. The exact displacement should be verified from the manufacturer's official documentation or the original equipment specifications. A proper displacement ensures that the pump can supply an appropriate volume of hydraulic fluid to power the different hydraulic actuators in the excavator, enabling smooth and efficient operation.
Operating Pressure
Rated Pressure: The rated operating pressure of this pump is typically around 300 - 350 bar (30 - 35 MPa). This pressure rating is essential for the effective operation of the hydraulic cylinders and motors in the 330GC excavator. It provides the necessary force to perform heavy-duty tasks like digging through hard soil or lifting heavy loads, ensuring that the excavator can operate with precision and power.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 400 bar (40 MPa) or more. This additional pressure capacity allows the pump to handle sudden peak loads during the excavator's operation, such as when breaking through tough rock formations or dealing with unexpected resistance, safeguarding the reliability and durability of the hydraulic system.
