| Comparing Ultrasound and Temperature When Monitoring Fan Bearings | ||||
Allan Rienstra, Editor |
Our
website and this newsletter
serves as a great forum for our fellow ultrasound inspectors to bounce
ideas and questions around and hopefully get some answers. SDT Training
Programs helps builds a solid community of inspectors who turn to us
when they have interesting ideas to share. We recently had a great
question from the ultrasound inspection team at Temple Inland in Texas.
The question was centered around using both temperature and ultrasound
data to confirm bearing condition prior to and after lubrication. The
responses, suggestions, and conclusions serve as pretty good reading,
especially if you are responsible for acoustic lubrication using AVM
technology at your plant. Here is the question from Temple: I use both ultrasound and temperature measurements on grease filled pillow block bearings. The bearings are 3 15/16" SKF 2220 grease filled variable speed (1500-1800 rpm) split housing used on fans. I keep coming up with the same results for these fan bearings. That is, when the temperatures get very high; as much as 50ºF over ambient; my ultrasound readings become much lower. The average dBµV data for all these bearings is 45 dBµV, but for high temperature measurements that ultrasound number drops to 27 dBµV. That is 8 times quieter! This appears strange to me as I would have believed that higher temperature would mean higher ultrasound. |

It has been thrilling
for us to watch all those companies who refuse to quit during the last 6
months economic crisis. What I mean is that we see a marked increase in
training requests from companies that are trying to slash costs to stay
in business. These companies recognize that despite bad economic times
it is still mandatory to invest in their core asset; their people.
Check our training schedule regularly to see new classes we've added.

Tom Murphy is a
corporate trainer for SDT as well as a consultant and author. He
recently provided a short white paper to the UK publication "Smart
Energy Decisions".
Saving energy has become disjointed in many large businesses. There is money to spend on excessive energy use. But there is no money to spend on reducing that usage. Maximizing your productivity is not in the hands of the production department, it is in the hands of the maintenance department. They are expected to carry out the surveys, tap into their own labour to make repairs, and use their already stretched budget to buy replacement parts. But in the end maintenance will not be credited with the success or with the savings. So, it doesn't get done. >> Read the whole story |
