Visual Inspections are still as important as ever!

02/22/2017

In the world of technology, more specifically maintenance technology, there are so many different tools we are using to make decisions. We use vibration analysis, ultrasonic analysis, motor current analysis, thermography, and so many other technologies that many times the most simple and cost-affordable technology is sometimes forgotten: YOUR EYES!

Visual inspections can tell you a lot about how a piece of equipment is running. Does it have clogged filters? is there an oil leak? is the oil level high? is it low? Is the fan cover plugged? are cooling fins plugged?

Tom Spettel, Senior Reliability Engineer, Category IV ISO Certified Vibration Analyst

The below video is a case study of a large 3-stage air compressor that was directly coupled to a 2-pole (3600 RPM) motor that had vibration problems after the air compressor was re-located to a different building. This was originally presented at the 2016 Reliability, Process, & Maintenance Symposium (RPM) in Kalamazoo, Michigan on September 13-14, 2016.

Recent Vibration Analysis & Continuous Monitoring Advances

10/10/2016

Information is everywhere in today’s world. It is the way individuals and companies alike make decisions. Insurance companies have a device you can plug into your car to gather information to tell them about your driving habits. They gather the information about you to make a rate determination on what they should charge you for your premium. Facebook, Twitter, the internet in general gives you so much social information, breaking news, etc. all this information is readily accessible and even alerts you when it happens. The “internet of things” or IOT is very active - Why should maintenance and reliability be any different?
