针对如何提高移架速度这一问题,运用仿真软件AMESim对液压支架推移千斤顶控制回路建立了仿真模型,并对移架过程进行了仿真,得出适当增大液控单向阀阀芯最大开口量和阀芯直径能够明显减小液压系统的局部阻力,提高移架速度,但这在一定程度上会影响系统的稳定性,为合理设计优化液控单向阀结构,提高煤矿的经济效益提供了参考。
Aiming at the problem of how to improve the moving speed, the simulation software AMESim was used to simulate the control loop of jacking jack of hydraulic support, and the simulation of moving process was carried out. The optimal opening of pilot valve And the diameter of the valve core can obviously reduce the local resistance of the hydraulic system and increase the moving speed of the moving system. However, this will affect the stability of the system to a certain extent and provide a reasonable design and optimization of the structure of the liquid-controlled check valve and the economic benefit of the coal mine reference.
