一种水泵选型方法

Method of pump selection

给出了水系统次不利环路概念。介绍了根据最大流量和次不利环路阻力损失选择水泵的方法。理论和实例分析证明 ,该方法比传统的根据最大流量和最不利环路阻力损失选择水泵的方法节能。

Puts forwards the concept of the second worst loop of water systems. Presents the way of selecting pumps according to the maximum flow rate and resistance loss of the second worst loop. A theoretic and example analysis shows that this way energy consumption is less than that of selecting pumps based on the maximum flow rate and the worst loop.
