In this tutorial,we will investigate several aspects of centrifugal pump efficiency.First I will define efficiency and give some examples.Next we will examine some of the design criteria that ultimately dictate the efficiency exhibited by a particular pump.We will also try to make that somewhat nebulas quantity,known as specific speed,more meaningful.I will also show its effect on the shape of a pump’s performance and power curves.Finally,we will discuss the importance of (or,sometimes,unimportance) of efficiency as it relates to a particular application or process.We will also illustrate the relationship of efficiency,head,and flow as they apply to both steep and flat performance curves and their roles in constant and variable speed applications.We will end with a brief look at the combined efficiency of a pump and its driver.

在本教程中,我们将探讨几个方面的离心泵效率.首先,我将定义效率和举几个例子.下一步,我们将探讨一些设计标准,最终决定展出由一个特定的泵效率.我们还将尝试,有些星云称为特定的速度,数量,更有意义.我也将显示其效果,对泵的性能和功率曲线的形状.最后,我们将讨论效率的重要性（或,有时并不重要）,因为它涉及到一个特定的应用程序或进程.我们还将说明效率的关系,头和流量,也适用于陡峭和平坦的性能曲线和常量和变量的高速应用的角色.我们将结束在简要介绍泵及其驱动器的综合效率.
