The Research on Based on Secondary Regulation of Swing System of Hydraulic Excavator

Abstract:

In order to recycle energy during rotary phase of hydraulic excavator in the braking, this paper proposes a hydraulic slewing system based on secondary regulation control. In the constant pressure network, secondary regulation system can make variable motor reach the set speed quickly and smoothly through the motor PID feedback control, which can control power of the whole system ,while the general volume transmission system mainly through changing the flow of pump. Accumulator is used to recycle braking energy and reuse for next acceleration,which improve work efficiency. The simulation results shows that the energy recovery and reusing efficiency of rotation braking recovery system are 65.9% and 47.3%, the system achieves the goal of energy conservation and emissions reduction.
