岭澳核电站二期工程循环水泵选型分析

Scheme Choice of Circulating Water Pumps for Ling'ao Nuclear Power Station Phase Ⅱ

近年来,混凝土蜗壳泵开始在我国得到应用,鉴于目前我国相关领域应用经验不多的情况,以岭澳核电站二期工程循环水泵的选型经验为基础,对立式金属混流泵和混凝土蜗壳泵的性能结构、方案选择和泵房布置等方面进行比较,分析了不同方案的特点以及岭澳核电站二期工程循环水系统采用混凝土蜗壳泵一机两泵方案的主要原因。

In recent years, concrete volute pumps have found applications in China. On account of the fact that the related application experience is not rich in China at present, with the experience of circulating pump choice of Ling＇ao Nuclear Power Station Phase II, the differences between vertical metal mixed-flow pumps and concrete volute pumps are compared from such aspects as performance, structure, scheme choice and pump house arrangement. The characteristics of different schemes as well as the main reasons for selecting the scheme of two concrete volute pumps per unit for the circulating water system of Ling＇ao Nuclear Power Station Phase II are also analyzed.
