STATIC AND DYNAMIC CHARACTERISTICS OF A PRESSURE-COMPENSATED FLOW CONTROL

摘要

This paper deals with static and dynamic characteristics of a pressure-compensated flow control valve for water hydraulic use by Danfoss. A mathematical model is derived and numerical simulation is performed, in particular, the stability of the circuit including the valve is analyzed. As a result, it is shown that the circuit becomes unstable depending upon the pipeline length connected to the valve, and that the upstream pipeline length is especially sensible to stability.
