  1. According to pump performance curve shown we can get that the distance h is changed with the rotate speed n in the same point q, and the flux q is changed with the rotate speed n in the same point h. from the curve we can get the rule that the distance and rotate speed are in direct with ratio at the same flux point, and the rotate speed and the flux are also in direct with ratio at the same distance point

    根據相似定律:流量與轉的一次方成正比;揚程與轉的二次方成正比;功率與轉的三次方成正比。在降低轉,調低水出水揚程的同時,功率下降的幅非常大,從中可以節省相當大的電能。完全應在高水位時降低水機組轉,從而使電機的輸出功率隨著轉下降值與轉原值商的三次方關系下降。
