Vibration Analysis

Vibration Analysis

The fist question asked is: "What is vibration analysis?"  Vibration analysis, if properly done can allow the user to evaluate a piece of equipment using frequency analysis with fast fourier transform data send from the data collector to generate a spectrum.  When the user interprets the data correctly, this can be very beneficial in diagnosing any machinery issues that may exist.  Some of these issues that can be found includes; gear defects, misalignment, loose mounting conditions, cavitation, bent shafts, and even bearing failures.  All data is stored and can be trended indefinitely on a piece of equipment.  Our highly trained technicians collect and analyze data follow the criteria of ISO 10816-3, any customer guidelines, as well as Hydraulic Institute (HI) standards. Reporting is also done using an online reporting tool called Tango.  

Vibration analysis extend the useful service life of your equipment and allow you to assess the repair quality on re-built machines.  A certified, experienced, Walling Company analyst interprets the data and provides you with a detailed summary of conditions occurring in your equipment.  Maximizing your capital investment, by reducing your maintenance and utility costs, decreasing machinery failures intervals, and increasing operational readiness.

Visual Inspection

It’s all about the details when it comes to Visual Inspections. When you can’t shut the machine or process down, what next?

Strobe Light Inspection and Digital Cameras are excellent resources used to view machine anomalies while the machine is operating.
