Design of Hydraulic System of Sway Machine Based on Electro-Hydraulic Proportional Control Technology

摘要

According to the problems of hydraulic system of sway machine, such as commissioning and maintenance are inconvenient, impact of change direction is big, system speed is slow, production efficiency is low, etc. It used electro-hydraulic proportional control valve to improve design in hydraulic system of sway machine. Application of electro-hydraulic proportional control valve has realized automatic adjustment of the hydraulic motor speed; it is effective to solve variable speed movement of sway machine frame and no impact of changing direction smooth. Commissioning and maintenance of sway machine are more convenient, and it improves performance of sway machine.
