温度变化下液压支架推移液压系统的性能优化研究

    Research on performance optimization of hydraulic support frame pushing hydraulic system under temperature variation

    • 摘要: 针对液压支架乳化液受温度作用影响其推移性能,在Amesim中建立液压支架液压系统模型,仿真分析温度变化带来的影响,根据仿真结果提出解决方法消除温度变化对推移液压系统性能的影响。首先,通过仿真分析,研究温度变化对液压系统活塞杆位移、速度及溢流的影响,然后根据温度变化带来的性能差异,提出改变管径、增加旁路的方法尽可能地消除温度变化对推移液压系统性能的影响。研究结果表明,在温度变化下,对推移液压系统速度的影响要大于对活塞杆位移的影响,采用扩大管径和增加旁路两者结合的方法消除温度变化带来的影响。本研究为液压支架推移液压系统的工程应用提供了有益的指导和参考,对提高系统性能和稳定性具有重要意义。

       

      Abstract: Aiming at the influence of temperature on the pushing performance of hydraulic support emulsion, the hydraulic system model of hydraulic support is established in Amesim, and the influence of temperature change is simulated and analyzed. According to the results, a solution is proposed to eliminate the influence of temperature change on the pushing performance. Firstly, through simulation analysis, the influence of temperature change on the displacement, velocity and overflow of piston rod in hydraulic system is studied. Then, according to the performance difference caused by temperature change, the method of changing pipe diameter and increasing bypass is proposed to eliminate the influence of temperature change on the performance of hydraulic system as much as possible. The results show that under the change of temperature, the influence on the speed of the pushing hydraulic system is greater than that on the displacement of the piston rod. The combination of expanding the pipe diameter and increasing the bypass is used to eliminate the influence of temperature change. This study provides useful guidance and reference for the engineering application of the hydraulic system of the hydraulic support, which is of great significance to improve the performance and stability of the system.
