供水系统的设计需要考虑到建设和运营成本。当安装需要抽水时，了解水泵的性能是决定运行成本的关键。到目前为止，在没有更好的估计的情况下，一直使用保守值来考虑泵效率。本文的目的是通过澄清水泵性能的价值来改善能源成本的确定。为此，对226台商用泵进行了研究，记录了最佳工作点的效率，以及流量、高度和泵类型等其他变量。结果发现，泵的性能和流量之间有很强的关系。这就产生了一条经验曲线，设计人员可以用它来预测泵的效率。结果在一个简单的案例研究中使用了格拉纳多斯优化系统。这些成果可以在设计政策中实施，以便在优化供水系统时更好地进行能源评估。
Water supply systems need to be designed accounting for both construction and operational costs. When the installation requires water pumping, it is key for the operational costs to know how well the pump can perform. So far, pump efficiency has been considered using conservative values, in the absence of a better estimation. The aim of this paper was to improve determining the energy costs by clarifying what the value of the pump performance should be. For this, 226 commercial pumps were studied, registering the efficiency at the optimum operating point, as well as other variables such as the flow rate, height, and pump type. As a result, a strong relationship between the pump performance and the discharge flow was spotted. That allowed the generation of an empirical curve, which can be used by designers to anticipate what pump efficiency can be expected. The results are used in a simple case study using the Granados Optimization System. These achievements can be implemented in design policies for a better energy assessment in the optimization of water supply systems.
