Exploring Influence Factors of Flow Rate During Pilot Stage of Jet Pipe Servo Proportional Valve

  • 摘要: 射流管喷嘴与接收器之间的流场存在淹没射流等复杂的流动情况,导致流场特性不易预测。在喷嘴形状为矩形的情况下,通过对矩形接收孔和圆形接收孔的射流管伺服比例阀前置放大器进行流场数值仿真,得到了喷嘴位移、接收孔与喷嘴的重合面积、射流管入口压力以及负载对先导级流量的影响。通过比较,发现先导级流量与射流管入口与出口的压差的开方成正比关系,喷嘴位移、接收孔与喷嘴的重合面积以及负载大小对先导级流量的影响较小。建立了射流管流场的等效液压桥路,推导出了先导级流量的方程,并通过泰勒展开式分析了影响先导级流量的因素。提出了流量接收率的概念,并分析了流量接收率对先导级流量的影响。
