【Abstract】 On the basis of numerous test data obtained on site the authors expounds the characteristic features of climbing and low frequency vibrations in a Chinese made 300 MW turbogenerator set and the causes of their emergence. Some technical measures have been recommended for their elimination. The on site test results obtained after the implementation of these technical measures indicate that the measures adopted have been very effective in eliminating the above mentioned vibrations.更多还原
