Product Description
K5V200DPH1HQR-0E02 Hydraulic Main Pump Hitachi ZAX470 K5V200DPH Excavator Hydraulic Pump Assembly Excavator Parts
The excavator hydraulic main pump is a key energy-converting device based on axial variable piston working principles. Driven by the engine main shaft, the cylinder block drives multiple piston groups to perform reciprocating motion. Through the isolation and oil distribution of the valve plate, the pump completes continuous oil suction and pressurization. The swash plate inclination directly determines piston stroke and pump displacement, and the external hydraulic regulator adjusts the swash plate angle in real time according to system load signals. Three integrated control systems form a complete hydraulic adjustment logic: constant power control matches pump output with engine rated power; load sensing control dynamically adjusts flow according to actual working demands; pressure cutoff provides ultimate overpressure protection. Wear on pistons and valve plates leads to internal leakage, while regulator sticking causes abnormal power output, which are the primary causes of hydraulic system failures.
