摘要
实验研究了提升高度为 6 7 m的涡流二极管泵的性能 .研究结果表明 :料桶内的液面高度对涡流二极管泵的泵效率及输送量影响甚微 ;抽吸压力对涡流二极管泵的扬程和流量分配比没有影响 ,但泵的平均流量和效率随着抽吸压力的增大而减小 ;当抽吸压力不变时 ,随压冲压力的增大 ,涡流二极管泵的扬程、流量分配比、输送量及装置效率都随之增加 .实验还表明在本实验条件下决定压冲过程流量分配比的关键因素是涡流二极管泵系统三通分流管路两侧的静压头之比 .
The experimental study on performances of vortex diode pump, including the lift height, the distribution ratio of liquid flow, the liquid conveying rate and efficiency, was conducted. The lift height was 6.7 m. Experimental results are as follows: (1) The liquid height in the tank has little influence on the performance of the pump. (2) The suction pressure has little influence on the distribution ratio of liquid flow and lift height except for the efficiency and liquid conveying rate. (3) The lift height, the distribution ratio of liquid flow, the liquid conveying rate and the efficiency increase with the increase of the discharge pressure. (4) The distribution ratio of liquid flow is mainly determined by the ratio of static pressure drop around T tube.
