Record vibrations of equipment to determine if there is a problem.
What does a Vibration Analyst do?
A Vibration Analyst detects the early precursors of machine failure. The work a Vibration Analyst does allows machinery to be repaired or replaced before an even more expensive problem occurs. If you’re a Vibration Analyst, you diagnose misalignment, imbalance, mechanical looseness, eccentric shafts, gear wear, broken teeth, bearing wear, loose rotor bars, and poor end turn connections. This kind of analysis can be applied to any type of equipment that rotates, such as electric motors, fans, machine tools, paper machines, turbines, conveyor belt drives, pumps, air-compressors, motor-generator sets, reciprocating engines, rolling mills, and mining equipment.
Basically, all kinds of rotating equipment vibrate, even if it’s just a little bit. But as the bearings age, they vibrate more and more. What you look for are those distinct vibrations that exceed the normal for that particular machine.
Much of your work is done using vibration analyzers, which are connected to the rotating machinery and record vibrations using sensors. The recordings are then transferred to a computer where you analyze the results with a special program. You compare the vibrations over a timeline, and when you notice a significant change, you contact the Vibration Technician. They fix the problem, and prevent the issue from becoming a full-blown disaster.
This method of monitoring expensive equipment keeps costs down for manufacturing agencies because you sidestep repairs and part replacements when none are needed. Moreover, you spot problems before the equipment completely breaks down.
