Frequently Asked Questions

What is vibration analysis?

Vibration analysis is an essential and valuable tool in a predictive maintenance program. Vibration analysis can identify the following problems and conditions: Deteriorating, Defective, Poor-fit bearings; Imbalance; Misalignment; Belt Issues; Gear defects; Belt and Coupling Issues; Motor Issues; Excessive operating conditions; Foundation and Mounting Issues.

What facilities could benefit from vibration analysis?

Industry, School Systems, Hospitals, Data Centers, Water Pumping Facilities, Waste Treatment Systems, Convention Centers, Malls, Facilities and Office Complexes.

Why does my facility need vibration analysis?

By incorporating vibration analysis in your overall maintenance plan, your company can reap the following “bottom line” benefits: Reduction in unscheduled downtime and catastrophic failures; Shortening of scheduled downtime; Extension of running time; Advanced Scheduling of Repairs Usually Reduces Overall Maintenance Costs

What does PVAC do?

PVAC addresses the following: Start Up Acceptance & Footprinting; Advanced Failure Detection; Rotating Equipment Analysis; Vibration Troubleshooting; Pre-Failure Alert – Recommendations; Simple and Complex Modal Analysis; Flow Induced Vibrations; Balance Issues

How is vibration analysis performed?

It all starts with a site visit and information gathering on all machine systems, bearings, fans, etc, that will be part of the route. From this information, a database will be created and a route will be programmed before the first onsite data collection will be initiated. Although some plants are just interested in foot printing their operations, most facilities find benefit from periodic data collection for trending for downtime reduction. Trending is the best use of Vibration Analysis when time allows.

What do I do with the vibration analysis results?

PVAC performs the diagnostics and submits recommendations for your maintenance team's consideration. With preventive vibration analysis your company can schedule and perform the needed maintenance so you can avoid equipment failure during production.
