泵特性曲线 meaning in Chinese

pumcharacteristic curve
pumcurve

By discussing in detail the shapes and types of pump characteristic curves and the effects of geometrical parameters on them , this paper points out that the main reason of the brake horsepower of the low specific speed sewage pump increasing with capacity rapidly is that we often select larger geometrical parameters such as b2 , ft and so on to enhance the capacity of the sewage pump
详细讨论了离心式排污泵特性曲线的形状和种类，以及几何参数对排污泵特性曲线的影响，指出排污泵设计中增大b _ 2 、 f _ t等几何参数是导致轴功率曲线随流量增加上升很快的原因。
