本文件描述了一种基于称为能效指数（EEI）的无量纲数值评估泵机组能效性能的方法。 本文件涵盖的泵装置包括: -一个或多个旋转动力水泵，包括集成在其他产品中的水泵，由电机系统驱动，包括电机，以及: -一种接线盒，只能在恒定的电机定子频率和（几乎）恒定的转速下操作泵装置，或 -CDM（完整驱动模块），可根据流量和/或排放或压差的变化需求，以可变转速运行泵装置。 注:CDM通常也称为VSD（变速驱动）。 就能源效率而言，上述泵装置被视为扩展产品。交叉引用: EN ISO 9906IEC/TS 60034-30-2EN 16480EN 60034-30-1EN 60034-2-1IEC 61800-9-2购买本文件时提供的所有现行修订版均包含在购买本文件中。

This document describes a methodology to evaluate energy efficiency performance of pump units based on a non-dimensional numerical value called Energy Efficiency Index (EEI). This document covers pump units consisting of: — one single or several rotodynamic water pump(s), including where integrated in other products, and driven by a motor system, consisting of an electrical motor, and either: — a terminal box which only enables to operate the pump unit at constant motor stator frequency and thereby (nearly) constant rotational speed, or — a CDM (Complete Drive Module) which enables to operate the pump unit at variable rotational speed depending on a varying demand of flow rate and/or discharge or differential pressure. NOTE A CDM is also often called VSD (Variable Speed Drive). Pump units as defined above are treated as extended products in respect to their energy efficiency.Cross References:EN ISO 9906IEC/TS 60034-30-2EN 16480EN 60034-30-1EN 60034-2-1IEC 61800-9-2All current amendments available at time of purchase are included with the purchase of this document.
