摘要
实验研究了喷嘴直径为5 mm,扩散管直径分别为5、7 mm,提升高度为6.7 m的气动式脉冲液体射流泵的性能。结果表明:料桶内的液面高度对气动式脉冲液体射流泵的效率、扬程、输送量影响甚微,而随着操作压力的增加,脉冲液体射流泵的效率、扬程、输送量也增大。证明了在本实验条件下,最佳喷嘴间距与喷嘴直径之比为0.8～2.0范围内,并讨论了不同喷嘴间距所对应的最低操作压力条件。
In this paper, experimental study on the performances of pneumatic pulsed liq-
uid jet pump, including the lift height, efficiency and liquid conveying rate, is carried
out. The diameter of nozzle is 5 mm, the diameter of diffuser is 5 mm or 7 mm and the
lift height is 6. 7m. Experimental results show that the liquid height in the tank has lit-
tle influence on the performance of the pump, however the efficiency, lift height and the
liquid conveying rate increase with the increasing of the operated pressure. The optimal
ratio of the distance between the nozzle and the diffuser to the diameter of the nozzle are
also given in the range 0.8～2. 0. The conditions of minimum operated pressure, corre-
sponding to different distance between the nozzle and diffuser are discussed.
