Optimized Design and Simulation of Working Arm Hydraulic System for High Efficiency Environmental Protection Equipment

Aiming at the shaking phenomenon during the working process of a high-efficiency environmental protection equipment working arm hydraulic system, taking the hydraulic system controlling the lifting action of the working arm as the research object, analyzing the reasons for the phenomenon, and carrying out the optimization design and simulation research of the anti-shaking hydraulic system. The research results show that: the working arm anti-shaking hydraulic system through the one-way throttle valve return back pressure and a reasonable choice of the balance valve pilot ratio, improve the flow matching degree of the balance valve, reduce its switching frequency, can significantly improve the stability of the working arm descending system, anti-shaking design effect is obvious. The results of the research on the optimization of special equipment hydraulic system design are of great significance.
