  • 产品描述
  • 最低效率指标(MEI)的意思是在最佳效率点(BEP)、部分负载(PL)和过载(OL)时的液压泵效率的无尺寸标度单位。 欧盟条例(EU)对规定自2013年1月起对MEI的效率要求>0.1,自2015年起对MEI的效率要求>0.4。自2013年1月起,市售最佳性能水泵的指示性基准由该条例规定。

    • The benchmark for most efficient water pumps is MEI ≥ 0,70.
    • The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter.
    • The operation of this water pump with variable duty points may be more efficient and economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system.
    • Information on benchmark efficiency is available at http://europump.eu/efficiencycharts.
    • The “Year of manufacture” is indicated on the product nameplate with a four digit number which is decoded as follows, YYWW with year (2 digits) and week (2 digits), e.g. PC 0223 for year 2002 and week 23. The number can be separate or it can be part of the model number, e.g. xxxxPX0223xxxx.
