  • Key functions & working principle
Working Principle 1. Engine power drives the pump shaft, rotating the cylinder block and pistons
2. Pistons reciprocate to draw hydraulic oil into the pump (suction stroke) and pressurize it (delivery stroke)
3. Load-sensing valve detects system pressure/flow demand, adjusting the cylinder block angle to vary displacement
4. Pressurized oil is delivered to hydraulic valves, which distribute it to actuators (cylinders/motors) to drive machine movements
5. Relief valve releases excess pressure if system pressure exceeds the maximum rating, preventing damage
Core Functions 1. Convert engine mechanical power into hydraulic energy for the entire hydraulic system
2. Supply stable, high-pressure oil flow to power all machine functions (digging, lifting, swing, travel)
3. Optimize energy efficiency via load-sensing control to reduce fuel consumption
4. Protect the hydraulic system from overpressure and contamination
5. Ensure smooth, responsive operation of the excavator
