Low Frequency Vibrations At Centrifugal Plants
MetadataShow full item record
Low frequency vibrations at centrifugal compressor and pump installations are usually discarded as unlikely. However, severe acoustically excited vibrations at frequencies as low as 5 or 10 Hz have been observed at a number of plants. The paper discusses some of the excitation mechanisms and techniques available for their control. Several field study examples illustrate typical problems and their solutions.
