摘　　要：【目的】深入研究鱼雷网式过滤器的水头损失和过滤时间。【方法】浑水条件下,对2种滤网目数的鱼雷网式过滤器分别进行定含沙量和定流量试验,分析了水头损失在不同运行条件下的变化规律。【结果】定含沙量试验中,进水流量在240～300 m3/h范围内持续增大时,水头损失发生急剧变化所需时间逐渐延长,而在300～360 m3/h范围内持续增大时,水头损失急剧变化所需时间逐渐缩短,这是鱼雷部件起到关键作用的缘故;定流量试验中,随进水含沙量增大,过滤器达到预设压差0.10 MPa的时间越短;所有试验条件下,水头损失随过滤时间的推移经历保持不变、逐渐减少和急剧增大3个不同的变化阶段。【结论】鱼雷部件在延长过滤时间方面起到重要的作用;鱼雷网式过滤器的冲洗预设压差值调节为0.04 MPa最宜。【Objective】The purpose of this paper is to study the head loss across the torpedo screen filter and the associated filtration time.【Method】Experiments was carried out using a muddy water at constant sediment content and constant flow.【Result】Under constant sediment content, the time it took the head loss to stabilize increased as the flow rate increased from 240 m^3/h to 300 m^3/h, while decreased for flow rate between 300-360 m^3/h. Under constant flow condition, the time it took the pressure drop to reach △p=0.10 MPa decreased as the sediment content increased. With the change in filtration time, the head loss experienced three different stages： remaining constant, gradually decreasing followed by a sharp rise.【Conclusion】Torpedo plays an important role in prolonging the filtration time, and the appropriate preset pressure for the torpedo screen filter was 0.04 MPa.
