疏浚泥泵的性能对泥沙输送管道的效率和安全起着决定性的作用。采用先进的 PIV（粒子图像测速法）技术研究小流量工况下泥泵的内部运动规律，得到泥泵内的速度分布，揭示了泥泵内部的流场分布、能量损失、水力效率等现象，表明 PIV 技术是一种研究泥泵内部流动规律的有效手段，为进一步实现固液两相流研究提供实验依据。

The performance of dredging pump plays a decisive role for the efficiency and security of sediment transport pipeline. Researching the velocity distribution in the internal motion of dredging pump by using advanced PIV measurement technology un-der small flow rate condition and revealing the flow field distribution,the dredging pump internal energy loss and hydaulic efficien-cy and so on.Proving that the PIV technique is an effective means to study the internal flow of the pump and providing experimen-tal basis for further study of solid-liquid two-phase flow .
