Model Compatibility: Specifically designed as the hydraulic main pump for SY75 excavators.
Pump Model: K3VL80
Function: Responsible for generating high - pressure hydraulic fluid to power the various hydraulic actuators in the excavator, such as the boom, arm, and bucket cylinders.
2. Technical Parameters
Displacement
Nominal Displacement: 80 cm³/rev. This parameter determines the volume of hydraulic fluid displaced by the pump per revolution of the drive shaft, which is a key factor influencing the flow rate 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 for the normal working conditions of the SY75 excavator, ensuring smooth operation of its hydraulic functions.
Maximum Flow Rate: Under specific operating conditions (e.g., at the maximum allowable speed), the pump can reach a maximum flow rate of [Z] L/min to meet high - load or high - speed operation requirements.
Pressure
Rated Working Pressure: The pump is designed to operate continuously at a rated pressure of [P1] MPa. This pressure provides sufficient force for the hydraulic actuators to perform their tasks effectively.
Peak Pressure: It can withstand a peak pressure of [P2] MPa for short - term, high - load situations, such as sudden heavy digging or lifting operations.
