Hi,
I just reported to the boss yesterday that one of our 150 H.P. compressor motors didn't sound right. I speculated that it might have a bearing or coupling problem. Damn guy had the gall to ask me what the plan was to fix it! I removed the guard & used a dial indicator to check the shaft runout & end play. I couldn't find any glaring reasons for the change of the "tone". Pretty hard to diagnose a rear bearing with a dial indicator in my experience. The bearing temperatures are normal. Maybe I just need to clean the old ears out. Maybe too much motorcycle riding over the weekend has "tweaked" my ear drums.
I mentioned that a vibration analyzer would be a good tool to have in the old tool box for these kinds of situations.
He is looking into the tool purchase. I was wondering if any of you guys used vibration analysis & had any success with it.
I suppose there are a lot of different types of analyzers. A lot different kinds of failure tolerance among bosses too! I suppose that if a bearing failure is prohibitively expensive, the monitoring costs are justified.
Feel free to leave opinions here!
