High 2X Piston Compressor.

Raul Rios
This is a Betico piston compressor which manifests 2X very high radially measured in its bearings. What is the reason? Is it a problem with the crankshaft? I do not know if the compressor has two or four pistons. Data of interest: 1X Motor: 1750 cpm 1X Compressor: 1023 cpm Drive: Pulleys. Thanks in advance for your comments. Rául Ríos.Read More...

Interesting DC motor reading. Any Ideas?

Recently changed a DC motor due to an outer race defect. The replacement motor had a different look to it for the baseline reading. All regular readings on both bearings show the same look.The spectrums between 0-12000 cpm are dominated by running speed harmonics and 1/3 running speed harmonics. I grabbed a high resolution reading and almost all the 1/3 harmonic peaks are sidebanded by 10.2 CPM sidebands. We even had the drive re-tuned and that had minimal affect on the readings. Any ideas...Read More...

Hi All, I am a new engineer working on my first project and wanted some feedback on some of my findings if possible. We have 8 identical closed loop cooling water systems that run medium sized centrifugal pumps. The pump performance places it quite close to the BEP operationally, but have been prematurely needing to change out bearings and mechanical seals over the last 20 years on the pumps and have had a history of high vibrations issues and running extremely noisy. There is definitely...Read More...
