英语翻译
The majority of municipal and commercial,clear water,applications are not restricted by the limitations outlined above and these pumps should be selected with efficiency in mind.If a pump is going to operate at a constant flow and head,it should be selected to operate as close to its BEP as possible.An example of this type of application would be a pump that feeds a municipal water tank.Since elevation and pipeline friction remain constant,the pump can be sized to meet its requirement at the best possible efficiency.

If a pump is going to operate at a constant flow and head, it should be selected to operate as close to its BEP as possible. An example of this type of application would be a pump that feeds a municipal water tank. Since elevation and pipeline friction remain constant, the pump can be sized to meet its requirement at the best possible efficiency.
如果泵要连续地,满负荷的运转,那么在选择泵时就要尽可能打出余量,该项应用的例子之一就是往城市储水(池)库里蓄水,因为水的提升高度和管线的摩擦力是不变的,就要选择最佳型号的泵,以便获得最佳泵水效率
