Abstract: At present,the energy efficiency evaluation of centrifugal pump units in China is still in the exploratory stage.In order to evaluate the energy efficiency level of the equipment quickly and accurately,based on the MVC model of the .NET platform,this paper designs and develops an automated evaluation system. On the basis of establishing the mathematical model of energy efficiency evaluation of pump units,the parameters are collected and processed. The data is imported manually or by accessing the database，and the energy efficiency calculation is performed according to the standard using a simple and highly accurate formula. The system is applied to verify the example，and the operating condition of the equipment is compared with the economic operation discriminate table to judge the operation of the unit. The results show that the evaluation results calculated by the software are accurate.Without complicated manual calculation,the evaluation time can be shortened,the work efficiency can be improved，and it has certain application value for industrial production.

摘要： 针对离心泵机组的能效评价，目前我国还停留在探索阶段。为了对设备的能效水平进行快速准确的评价，基于.NET平台MVC模式对整体进行架构，设计开发了一套自动化评价系统。在建立泵机组能效评价数学模型的基础上，对各参数进行采集处理；将数据通过手动或访问数据库的方式进行导入，依据标准，采用简单、精度高的公式进行能效计算；应用该系统进行实例验证，将设备的运行状况与经济运行判别表进行比对，判断机组运行情况。结果表明，采用该系统得到的评价结果准确；无需进行繁琐的手动计算，可缩短评价时间，提高工作效率，对工业生产具有一定的应用价值。
