通过实验获得了水力驱动控制棒步进的动态过程。揭示了水力驱动控制棒的作用机理 ,详细分析了其动态特性与控制棒、组合阀性能参数及组合阀操作之间关系。结果表明 :控制棒的步进是组合阀输出的流量脉冲、压力波 ,和步进缸运动产生的大阻尼压力振荡的共同作用过程 ;步进缸的性能参数限定了其静止平衡状态的流量范围 ,和其步进过程吸收流量脉冲和压力波的能力 ,而组合阀的性能参数决定了步进缸静止平衡、延时平衡、流量脉冲和压力波的量值 ,两者的合理匹配确定了控制棒的步进状态。
The dynamic process of stepping hydraulic control rod was obtained through experiments. The mechanism of hydraulic control rod is revealed. The relationship between dynamic characteristics and control rod, valve performance parameters and operation of combination valve is analyzed in detail. The results show that the stepping of the control rod is a combination of flow pulse, pressure wave and large damping pressure oscillation caused by the movement of the stepping cylinder. The performance parameters of the stepping cylinder limit the flow range of the quiescent equilibrium , And its step-by-step process to absorb the flow pulse and pressure wave ability, and the performance parameters of the combination valve determines the stepper cylinder static balance, delay balance, flow pulse and pressure wave, the reasonable match determines the control Great step state.
