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。
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.
