REPEATABILITY ISSUES? IS ANYTHING ELSE AFFECTING YOUR ALIGNMENT RESULTS?
During the “heat of the battle” to get the precision shaft alignment job finished it is easy to overlook simple items that can cause unexpected results, non-repeatability, and soft foot issues. Here are some examples;
ALIGNMENT AND VIBRATION: WHAT IS THE CORRELATION?
This is a subject that comes up relatively frequently with our customers and observations from the field. The purpose of today’s blog post is to illustrate what can and often does happen. While misalignment can and does present with easily identifiable vibration signals; often it does not. Misalignment may be present in a machine, developing forces detrimental to machine and component life; while at the same time NOT producing a vibration signature easily distinguishable from unbalance or looseness. Further, depending on machine design and duty, misalignment may be present and not produce substantially elevated vibration at all.
