What is Vibration Analysis?
Vibration Analysis is an essential pro-active maintenance tool for building increased equipment reliability. It is the most commonly used technology in the industry today. It can aid in determining early what potential issues may cause machine failure. Early detection can help prevent costly downtime.
What can a Vibration Program from PMT bring to the table?
Cost reduction is critical in today’s challenging business environment. Catastrophic and/or non-planned down times can greatly add to operating costs. Maintenance teams must find ways to prevent catastrophic equipment failures and be able to schedule needed or required outages for planned repairs. Increased equipment reliability is a direct path to reduction of operating costs and the possible resulting liabilities.
Vibration analysis is a powerful tool that will help save maintenance costs by:

What is Advanced Vibration?
By performing Advanced Vibration, PMT can dig "deeper" into your machine and "see" what's really going on. We take more readings and perform a Bump Test and Phase Analysis. We then take this data to our own Certified Vibration Analysis team in order to diagnose the issue(s) at hand. We report back with a detailed, yet easy to read analysis with recommendation(s) to address any problems requiring any attention.
A Bump Test is a type of vibration test that is normally run on a non-operating machine. The machine is instrumented with one or more vibration transducers, and it is then impacted with a massive object such as a hammer. The machine will respond to the impact "bump" by a vibration that will die away, and the signals from the transducers are recorded and fed into a spectrum analyzer. The resulting spectrum will contain peaks that correspond to the natural frequencies, or "resonances" of the machine. In any machine, the vibration excitation forces from its normal operation should be well away from the natural frequencies to avoid resonant responses that can cause very high and destructive vibration levels.
Phase is the position of a rotating part at any instant with respect to a fixed point. Phase gives us the vibration direction. For example: tuning a car engine using a timing light and inductive sensor is an application of phase analysis.
All industries can benefit from Phase Analysis. PMT can perform a phase analysis on problematic equipment when the source of the vibration is not clear, or when it is necessary to confirm suspected sources of vibration. This analysis may include points measured only on the machine bearings or it can include points over the entire machine from the foundation up to the bearings.
