电液比例恒压阀的理论特性和实验研究

Theoretical Behavior of Proportional Electro-Hydraulic Valve of Constant Pressure and Its Experimental Investigation

本文从探讨电液比例恒功率控制液压马达的静、动态性能出发,寻求满足控制系统要求的恒压控制阀,确定它的主要结构参数。本文作者所研制的电液比例恒压阀经台架实验证明:理论分析同实验结果基本一致,满足了这种马达的恒功率变量控制系统的要求。

Starting with the discussion on the steady and transient characteristics of hydraulic motor with constant power using electro-hydraulic proportional control, a control valve with constant pressure which agrees with the requirements of control system is developed and the principal structural parameters of the valve are determined in this paper. After the valve developed by the authors of this paper being tested on the rig, it is shown that the theoretical analysis is basically consistent with the experimental results so that the requirements of variable displacement control system with constant motor power are met.
