渣浆泵厂家通用性能曲线
    把不同转速下的Q-H曲线画在同一张图上，并把各转速下效率相等的值投射到相应转速的Q-H曲线上，把这些等效值的点连成曲线称为等效率曲线。这种特性曲线称为泵的通用特性曲线，如图2 -45所示。利用通用特性曲线，就可以方便地确定出在任何一-组(Q、H)值下的转速(n)与效率(η)值。

五、综合特性曲线

把不同叶轮外径下的Q B、Q-n关系曲线表示在同一张图中， 如图2 -46所示，称变叶轮外径的综合特性曲线。
    同样，把不同时开安放角度的Q-H、0-η关系曲线表示在问张图中， 如图2-4所示，称变角度的综合特性曲线。渣浆泵

General performance curve of slurry pump manufacturer

The Q-H curves at different speeds are drawn on the same graph, and the values of equal efficiency at each speed are projected onto the Q-H curves at the corresponding speed. Connecting the points of these equivalent values into a curve is called equal efficiency curve. This characteristic curve is called the general characteristic curve of the pump, as shown in Figure 2-45. By using the general characteristic curve, the values of rotational speed (n) and efficiency (η) under any group (Q, H) can be easily determined.

V. comprehensive characteristic curve

The relation curve of Q B and q-n under different impeller outer diameter is shown in the same figure, as shown in figure 2-46, which is called the comprehensive characteristic curve of variable impeller outer diameter.

Similarly, the Q-H, 0-η relation curves with different opening and setting angles are shown in the tension diagram, as shown in Figure 2-4, which is called the comprehensive characteristic curve of variable angle. Slurry pump
