The excavator hydraulic pump acts as the "heart" of the hydraulic system, converting engine mechanical energy into hydraulic power to drive actuators (e.g., cylinders, motors). Its core principle relies on the reciprocating motion of pistons within cylinders, cyclically altering chamber volume to suction and pressurize oil. As a variable-displacement pump, it dynamically adjusts output flow based on load demand, delivering stable high-pressure (35MPa+) power for precise digging force while optimizing energy efficiency.
