How to Determine a Vertical Pump’s Natural Frequency

August 29, 2017

There are two commonly used testing methods to determine a vertical pump’s natural frequency. The first method is called a startup or coast down. In order to perform this method a tach signal is required for the speed to be tracked.  The pump is started and the amplitude and phase are recorded during start-up and […]

The Value of Continuous Vibration Measurements

August 5, 2014

Advanced vibration analyzers like the VibXpert have powerful analytical features that often go underutilized. One such feature is the ability to acquire continuous (live) vibration measurements. This can be utilized to check for measurement signal stability and quality. However,  it can also be used for additional analytical troubleshooting as well. Continuous (live) vibration data can […]
