Description
Summary:This paper takes the servo valve front accumulator as the research object. It analyzes its effect in suppressing pressure shock and improving system pressure stability. Finally, it achieves the purpose of improving the control accuracy of the hydraulic screw-down system of the rolling mill. According to the actual operating requirements, the mathematical model of the servo valve front accumulator is established. The pressure shock suppression effect of the accumulator is simulated and analyzed with different parameters in the process of servo valve adjustment and reversal. Finally, it is verified by experiment. The optimal selection method of the parameters of the accumulator is obtained to provide theoretical and empirical support for the study of methods to enhance the system pressure stability and improve the control accuracy.
