| Abstract: | The vibration problem resulted from misalignment of shaft system for targe-capacity turbo-generator sets is comparatively prominent,affecting safe operation of the units.Taking some type 600 MW units as examples,the characters of vibration trouble resulted from misalignment of three kinds,namely misalignment of generator-collector ring coupling,elevation deviation of bearing brackets between low-pressure cylinder and generator,and uncoaxiality between rotor and cylinder,for one type 600 MW turbo-generator s... |
