Consequently the penalty is approximately $3400/kW for the
above example.
The pumping station designer can influence to some extent the
type of pump required by distributing the total delivery flow over
the appropriate number of pumps.The highest possible efficiency
is to be obtained by suitable choice of the number of pumps and of
the speed of rotation.There is an illustration of the relative peak
efficiency for several pump types in Figure 7.
Polishing the impeller flow channels has an influence on the
efficiency of water transport pumps.The costs of improving the
efficiency this way are low in comparison with those of the
complete plant.
An example of the approximate cost distribution for a water
transport system in the Middle East is given here.It has to be noted

因此,刑罚是大约3400美元/千瓦以上的例子。抽水站设计可以影响到一定程度所需泵的类型分配总配送流程的适当数量的泵。最高的效率得到合适的选择的数量和速度的旋转泵。有插图的相对峰效率的几个类型的泵在图7。抛光叶轮流道有一个影响效率的水输送泵。成本提高工作效率,这是比较低的完整的植物。一个例子,大致成本分配水运输系统在中东是在这里。有一点需要注意,具体的能源需求在3千瓦时/米是10倍的价值,适用于一个正常的欧洲安装,由于数字8。轴向推力测量横向分裂,管道长度大得多。
