| 中文摘要 | 可逆流体换向装置是决定气动式脉冲液体射流泵的流体输送效率的关键组成部件。通过试验研究了不同入流结构、不同出流结构、面积比、引流间隙等因素对可逆流体换向装置输送性能的影响。结果表明:较大的入流射流出口速度可以产生更好的引流效果;带较长接收管的出流结构总体上的流体输送效果不如无接收管的出流结构;由于涡流分离导致的沿壁返流,过大的面积比将导致引流效果变坏,最优面积比值选取1.5为宜;当引流间隙长度和出流结构入口直径的比值为0.9~1.0时,不同出流结构的引流效果均较好。; The Reverse Flow Diverter(RFD) is one of the key components affecting the liquid-delivered efficiency.The effects of inflow structure,outflow structure,area ratio and suction gap on the performance of RFDs were studied in this paper.It can be found experimentally that expected entrainment phenomenon can be achieved when the outlet velocity of fluid for RFDs′ inflow structure is sufficient.There is less liquid delivered by an RFD with a long receiver than that without a receiver.Because of back-flow caused by vortex separation,oversize area ratio cannot have better entrainment phenomenon and the optimum area ratio is 1.5.When the ratio of suction gap length to inlet diameter of outflow structure is 0.9～1.0,the excellent liquid-delivered efficiency can be obtained. |
