查询词典 lift pump

Can be seen, no overload is the essence of the centrifugal pump, pump shaft power curve peak, or shaft power with the increase of flow rate changes are small, relatively flat power curve that axis, so that the pump shaft power in the dead lift off to zero head (that is, from zero flow to maximum flow rate) are less than equal to the original context of the supporting motive power.

可见，无过载离心泵的实质是指，泵的轴功率曲线有峰值或轴功率随流量的增加而有较小的变化，即轴功率曲线比较平坦，使泵的轴功率在关死扬程到零扬程范围内都小于等于原动机的配套功率。
