The displacement of the hydraulic pump for the CAT 336GC excavator is a key parameter. It is likely to be in the range of 120 - 180 cubic centimeters per revolution (cm³/rev). This displacement value is carefully determined to meet the hydraulic power demands of the excavator, which is utilized for various tasks such as arm movement, bucket operation, and rotation. The precise displacement should be verified from the manufacturer's official documentation or the original equipment specifications. An appropriate displacement ensures that the pump can supply an adequate volume of hydraulic fluid to power the different hydraulic actuators in the excavator, facilitating 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 functioning of the hydraulic cylinders and motors in the 336GC excavator. It provides the necessary force to execute heavy-duty tasks like digging through hard soil or lifting substantial loads, ensuring that the excavator can operate with precision and power.
Maximum Pressure: The maximum pressure that the pump can endure 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.
