What is Vibration Analysis? Why Vibration Analysis is required before Dynamic Balancing?
“Vibration Analysis” is a process of measuring the frequencies and vibration levels of machine to pinpoint the main cause of vibration in machine by analyzing the whole data collected.
Vibration Analysis is necessary before dynamic balancing because in a Rotary Machine vibration is the first indication of defect and it may be due to one or more than one causes at a time. Therefore, vibration analysis is very necessary to pinpoint cause of fault.
Following fifteen causes of vibrations are found very common in the Rotary Machines:
- Imbalance of Rotor
2. Bent Rotor Shaft
3. Eccentric Rotor Shaft
4. Twisted Rotor Shaft
5. Mechanical Looseness
6. Structural and Rotor Resonance
7. Misalignment of Rotors
8. Rotor Rubbing with Stator
9. Journal Bearing Faults
10. Roller Bearing Faults
11. Gears Faults
12. Electric Faults
13. Belt Faults
14. Electric Faults
15. Fluid Flow Turbulence Faults
“VIBRATION IS VERY DANGEROUS, CONTROL IT AND INCREASE YOUR PROFITS”
Dynamic Overloading due to Hammer of Unbalance produces Vibration, and you must control it.
Vibrations damage bearings, rotor and foundation. Control it and save your Repair losses.
Vibrations waste extra electric power continuously. Control it and save your Power losses.
Vibrations reduce production quality. Control it and increase your Production and Profits.
Vibrations increase chance of sudden breakdown. Control it and save your Machine Life.
Vibrations increase the repairing & maintenance cost. Control it and decrease Repair Cost.
Accidental breakdown cause wastage of raw material. Control it and save Raw Materials.
Vibrations create stresses in the structure. Control it and increase your Machine Useful Life.
Vibrations create shocking effect & teasing noise. Control it and create relax environment.
Your profits depend on useful life span, quality and reliable operation of your costly machines.
