The Application of Helium Mass-spectrometry Technology in Leakage Detection for Large-sized Turbine Units

By citing a few typical examples of practical problem solving with the use of helium mass spectrometry technology this paper expounds the latter's application in turbogenerator leakage detection and recommends a series of specific techniques for its effective use. The authors hold that thanks to its marked advantage in high measurement precision coupled with a scientific diagnostic method the helium mass spectrometry technology has firmly established itself in the new arena of tackling and resolving a variety of leakage problems specific to large sized turbogenerators.
