Ninety percent of all machine failures are signaled months, even years, in advance by changes in machine vibrations. Some future failures are even predictable upon initial start-up. By understanding a machine's vibration "signature," you can diagnose, solve, and prevent problems, as well as reduce the cost of maintenance.Machinery Vibration: Measurement and Analysis will show you how to use state-of-the-art instrumentation, tranducers and fast Fourier transform (FFT) spectrum analyzers-to monito machine conditions using the vibration signature. This expert sourcebook includes: Case histories that illustrate strategies for solving machinery problems-from unblanaces and misalignments to vortex flow and turbulence. A diagnostic chart for assessing the severity of vibration. An overview of technology used in 'trending' machine performance. Guidelines for setting up a vibration monitoring system. Many illustrations throughout the book. Whether you're a plant or mechanical engineer, maintenance engineer, facility manager, mechanic, or technician, this excellent book will enable you to troubleshoot mechanical problems and improve machinery performance. Victor Wowk, a registered professional engineer, is the President of Machine Dynamics, Inc., an engineering firm specializing in machinery vibrations, based in Albuquerque, New Mexico. He has extensive field experience in vibration analysis, which includes machinery diagnostics and applying corrective techniques. Mr Wowk is an instructor for both in-plant and public Machinery Vibration Workshops. |
