根据大量的现场试验结果 ,论述了某国产 30 0MW汽轮发电机组振动爬升与低频振动的特征及其原因 ,提出了消除机组振动爬升与低频振动的技术措施。实施这些技术措施后的现场试验结果表明 ,本文提出的消除该类机组振动爬升与低频振动的技术措施是非常有效的
According to a large number of field test results, the characteristics and reasons of vibration climb and low frequency vibration of a domestic 300MW steam turbine generator set are discussed. The technical measures to eliminate the vibration climb and low frequency vibration of the unit are proposed. The field test results after the implementation of these technical measures show that the technical measures proposed in this paper to eliminate the vibration climb and low frequency vibration of such units are very effective
