平行通道管间脉动试验过程中系统不稳定现象分析

Analysis of System Instability Phenomena of Flow Pulsating Test in Parallel Channels

在平行通道管间脉动试验过程中,系统出现了同频率等幅同相脉动和水锤现象。本文对此进行分析讨论的结果表明,回路系统中混凝器的存在容易引起系统的流动不稳定。用文丘里管流量计测量脉动流量除了应考虑测量系统的动态测量要求外,还必须对测量的平均流量和振幅加以修正。

The phenomena,including the water hammer and hydraulic pulsation with same phase,appear in the test of flow pulsation in parallel channels.These phenomena are discussed in this paper.The mixing condensator in the loop is the source of flow pulsation,and the means of flux and the range of pulsatile flow based on the Venturi tube in pulsatile flow condition should be corrected with propriety.
