摘要
根据液压支架筒式过滤器的工作特点,对极端工况下由于液流突然停止导致过滤器壳体内液压冲击的机理进行分析;运用滑移网格技术、三维非稳态Navier-Stokes方程和标准的K-e湍流模型分别对不同管路布置、不同壳体结构形式在极端工况时筒式过滤器液压冲击幅值进行动态仿真分析并对比,通过旋转蝶阀来模拟负载的周期变化;该计算仿真结果为综采工作面筒式过滤器的布置和设计提供理论参考。
According to the working characteristics of analysis of hydraulic impact caused by the sudden stop means of sliding mesh technique, unsteady reynolds-av standard K-e turbulence models hydraulic support cartridge filter,mechanism of cylinder in extreme conditions is done; By eraged Navier-Stokes (RANS) equations with simulation analysis and comparison of the cartridge filter hydraulic impact amplitude is done for different piping arrangement and shell structure form in extreme conditions the load cycles is simulated using rotating butterfly valves. The simulation results will provide theoretical reference, for the arrangement of the cartridge filter and the design of fully mechanized working face.
