This is a single source reference for process machinery diagnostics, vibration analysis, and troubleshooting. It includes usable computations, analytical procedures, definitions, explanations of fundamental machinery behavior, rotordynamics, static and dynamic measurements, data acquisition and processing, data interpretation, plus field proven problem-solving techniques. The book begins with fundamental concepts of lateral and torsional mechanical motion, and expands these basic models into acceptable simulations of real machines. Steam, gas, and hydro turbines, gear boxes, centrifugal and reciprocating compressors, pumps, expanders, motors and generators are analyzed from multiple perspectives. This text describes common malfunctions, plus unusual excitations and failure mechanisms. It is extensively illustrated, and contains detailed examples with sample calculations -- along with 52 case histories that cover entire scenarios, from problem definition through corrective solutions. For anyone responsible for maintaining industrial machinery and diagnosing problems in refineries, chemical plants, power plants, paper mills and other processing facilities.
