摘　　要：探讨非恒定条件下射流泵性能及与频率有关的管道摩阻损失 ,并与恒定流进行对比试验。试验结果表明 ,在相同的条件下 ,非恒定流射流效率比恒定流效率高。在频率 f=1～ 2Hz范围内 ,频率越高 。This paper studies the performance of jet pump and the functional loss of pipe related to the frequency on flow,and compares with the steady flow.The results show that the performance of jet pump on unsteady flow(f=1～2Hz)is better and more efficient than the performance on steady flow.There is more frictional loss of the pipe on unsteady condition,when the frequency is increased.
