摘要

电磁换向插装阀广泛应用于高压大流量液压系统中,其开关特性直接影响系统的快速性和稳定性。在建立电磁换向插装阀数学模型的基础上,通过仿真和实验,得出阀的开启和关闭时间不一致的结论。主阀的弹簧刚度、流体阻力R、系统压力、外负载特性等对开关特性的取值有较大影响,并给出了影响规律,为电磁换向插装阀的合理应用奠定了理论基础。

Simulation and experimental research on dynamic characteristics of the electromagnetic reversing cartridge valve
Electromagnetic reversing cartridge valve is widely used in high pressure and large flow hydraulic systems, and its switching characteristics influences the rapidity and stability of the system directly. Based on the mathematical model of the electromagnetic reversing cartridge valve, by the way of simulation and experiment, the result is that there is the discrepancy in time when the values open or close. Spring stiffness of the main valve, fluid resistance R, system pressure, characteristics of external load and so on, have comparatively large effect on the switching characteristics of the value and the effect rules are given, which lay a theoretical foundation for the rational application of electromagnetic reversing cartridge valve.
