摘要
针对目前无法快速准确的诊断液压支架工作过程中液压系统阀芯卡滞故障的问题,以ZF5600/16.5/26支架为例,研究电液换向阀阀芯卡滞问题对立柱升柱承载过程的影响。利用AMESim仿真软件建立立柱控制回路模型,以不同阀芯开启度代替阀芯卡滞状况,得出不同阀芯卡滞状况下立柱升柱特性曲线,通过对比分析不同曲线变化状态,可快速锁定出错液压阀位置,提高检修效率,防止故障危害蔓延。
iming at a quick and accurate valve core stagnation diagnosis of hydraulic system in the working process of hydraulic support, this paper studied the influence of electro-hydraulic directional control valve core stagnation on the prop loading process of column with support ZF5600/16.5/26 as an example. A column control loop model was established by using AMESim simulation software. The prop characteristic curve in different stagnation conditions was obtained by replacing stagnation conditions with different opening degrees of the valve core. The hydraulic valve fault could be located quickly by analyzing the variation of the two different curves so as to improve maintenance efficiency and prevent damage spreading.
