Analysis on Type Selection of Circulating Water Pump for Large Steam Turbines
摘要
Abstract
The improper selection of circulating water pump type may affect the revamping effect directly and does not occur rarely.Based on the analysis of the selection principles,it is proposed that the key is to match the design working point of the circulating water pump with the resistance characteristics of the circulating water system.In addition,the resistance characteristics of the circulating water system from actual measurements can provide scientific support for the selection of the circulating water pump types.Taking the upgrade of a 300 MW steam turbine as an example,the selection of circulating water pump type is based on the measured resistance characteristics of the circulating water system.The selected circulating water pump type is more scientific and reasonable than that in the original design.关键词
