| Resumen: | This document is the fourth part of a series of standards describing a methodology to evaluate energy efficiency performance of submersible multistage pump units (MS-S), comprising a rotodynamic pump part and a submersible motor which is either directly fed from the grid or combined with a frequency converter (CDM) to form a Power Drive System (PDS). For consistency with other referred standards CDM is used in this document. VSD for variable speed drive is the term used in Ecodesign regulations. Rotodynamic pump and motor are designed with outer diameters and special design features that enable to installed them in boreholes and operate them completely surrounded by the pumped liquid. The methodology is based on a non-dimensional numerical value called Energy Efficiency Index (EEI). An EEI value allows the comparison of different configurations by one common indicator. Physical influences such as size and stage number of the incorporated rotodynamic pump, unit part-load operation, motor-efficiency characteristic and frequency converter influence are implemented into this metric. |
