【摘要】:蓄能器充液特性对液压系统的压力稳定有重要作用。该研究对牙轮钻机充液系统的充液特性及其关键结构元件——充液阀特性进行研究。在蓄能器充液过程中,对充液阀进行机理分析,建立数学模型,搭建AMESim仿真模型,得出蓄能器在工作状态下的压力、流量随时间变化的变化规律,揭示了充液阀满足充液系统性能要求。
[Abstract]:The filling characteristics of accumulator play an important role in the pressure stability of hydraulic system. In this paper, the liquid filling characteristics of the filling system of the rotary drilling rig and the characteristics of the liquid filling valve, which is the key structural element of the drilling rig, are studied. In the process of accumulator filling, the mechanism of liquid filling valve is analyzed, the mathematical model is established, and the AMESim simulation model is built. The variation law of pressure and flow rate of accumulator with time is obtained, and it is revealed that the liquid filling valve meets the performance requirements of liquid filling system.
