Model Compatibility: Specifically designed for use in PC200, ZX330, and EC220 excavators.
Pump Model: K3VL45
Function: Serves as the main hydraulic pump, responsible for generating and supplying high-pressure hydraulic fluid to power various hydraulic components in the excavator, such as cylinders and motors, enabling the smooth operation of digging, lifting, and other functions.
2. Technical Parameters
Displacement
Nominal Displacement: 45 cm³/rev. This determines the volume of hydraulic fluid displaced by the pump with each rotation of the drive shaft, directly affecting the flow rate and power output of the pump.
Flow Rate
Rated Flow Rate: At a rated speed of [X] rpm, the rated flow rate is [Y] L/min. This flow rate is optimized to meet the normal operating requirements of PC200, ZX330, and EC220 excavators, ensuring efficient and stable operation of the hydraulic system.
Maximum Flow Rate: Under specific high-demand conditions, the pump can reach a maximum flow rate of [Z] L/min to provide sufficient power for heavy-duty operations or rapid movements of the excavator's working components.
Pressure
Rated Working Pressure: The pump is designed to operate continuously at a rated pressure of [P1] MPa, which is sufficient to drive the hydraulic actuators in the excavator to perform their tasks effectively under normal working conditions.
Peak Pressure: It can withstand a peak pressure of [P2] MPa for short periods during high-load operations, such as when dealing with tough digging conditions or sudden heavy loads.
