摘要

唐山发电总厂捷制ＣＣＶ１２５／１３型给水泵原设计效率仅６０％，现已运行４０多年，泵内过流部件已严重冲刷、磨损，运行效率只有３８．２４％，单位电耗高达１０．６４ｋＷ／ｔ。通过技术改进，泵的流量和扬程都比原泵设计值高，效率达到７１．６５％，比改前运行效率提高了８７．３７％，单位电耗下降了４．７５ｋＷ／ｔ，年节电３９０多万ｋＷ·ｈ。

Abstract

CCV125/13 feed water pump

with a design efficiency of only 60%

has an operation history of more than 40 years.With inner parts in the flow path being seriously eroded and corroded

the pump had only an operation efficiency of 38.4% and a power consumption of 10.64 kW/t.This pump was then retrofitted with higher flow rate and discharge head.The efficiency of the pump was improved then to 71.65%（33.45% higher than before） and its power consumption was decreased by 4.75 KW/t（annual saving of 390 kW·h）.
