AI Technical Summary
In multi-cylinder synchronous hydraulic systems, inconsistencies in the manufacturing and assembly tolerances of hydraulic components can lead to dragging, pressure buildup, and oscillation during synchronous control of hydraulic cylinders, affecting equipment stability and safety.
The system employs an independently configured first directional valve and hydraulic lock valve assembly. Through the P2 port of the shuttle valve, it dynamically connects with the oil pump, actively opening the reverse conduction capability of the hydraulic control check valve to provide a controllable pressure relief channel for the return oil chamber and avoid repeated impacts from the hydraulic lock.
It effectively suppresses the flutter and impact of the actuator components, enhances the operational safety and smoothness of the equipment under complex working conditions, and improves the operational stability of the multi-cylinder synchronization system.
