Dec 19, 2019 Screening for high overall vibration levels might seem like a logical first step. But overall vibration alarms will miss many emerging faults, because acceptable vibration levels from imbalance and flow turbulence on pumps and fans and background vibration often will mask low amplitude vibration from bearings and other critical components.

A Vibration Analyzer is an instrument used to measure, store and diagnose the vibration produced by machinery. It uses FFT based tools to display the magnitude of the vibration as it varies over the frequency. The primary use is to identify and predict faults in industrial machines as well as the causes that originate them.

2 ANALYSIS METHODOLOGY. The vibrating screen from which the springs were taken presents two types of loading over them: the first, a static load due to the weight of its components and the material it processes; the second, a dynamic load due to the exciters that produce the screen vibration. The combined effect of both types of loading causes ...
