摘要

大同第二发电厂１、３号机组凝汽器铜管由原来　的ＨＳｎ７０－１Ａ换成ＨＳｎ７０－１Ｂ，投运３个月后就发生了频繁泄漏。经分析认为泄漏是因管子的的　跨距过大产生振动所致。采取了相应的防范措施后，此问题得以解决。

Abstract

The condenser tubes of HSn70-1B on turbine №1 and №3 at Datong Thermal Power P lant №2

which had been renewed from original tubes of HSn70-1A

have frequentl y leaked after three months from putting into operation. Through analysis

it is believed that the cause of tube leakage is due to the span length were too larg e

resulting in occurence of pipe vibration. Appropriate counter-measures have b een taken

enabling the said problem to be resolved.
