Research on the Dynamic Characteristics of Pressure Compensation Valve in Load Sensing Multi-Way Valve

Abstract

Taking pressure compensation valve in load sensing multi-way valve as research object, based on the dynamic mathematical model, the dynamic characteristics and the law that the structure parameters affected the characteristics were analyzed. The research methods and results provide analytical tools and design documentation for the structure design and the theoretical study on the outlet pressure compensation multi-way valve.

Design and Analysis of a Flow-Control Valve With Controllable Pressure Compensation Capability for Mobile Machinery

“…In order to improve the characteristics of flow-control valve, scholars took the pressure compensator as the object and analyzed the influence of parameters such as spring stiffness, hydraulic power, the flow field in the valve, and load changes on the accuracy and stability of flow control [19]- [21]. For great control stability, Yang [22] designed the structure optimization scheme of "a small spool, double port" three-way pressure compensator, which reduces the system pressure shock…”

Research on Damping Characteristics of Throttle Valve of Feedback Circuit in Pressure Compensation System

“…So that the operator can adjust the speed of the working device stably only by using joystick to change the opening degree of the multi-way valve, thereby improving maneuverability of engineering machinery and working precision [1]. And pressure compensation system can also realize composite action of each working device in a single pump system, which makes the flow distributed according to their needs and not affected by load changes [2].…”
