With the use of a high intensity strobe light or photo eye, the exact angle of displacement is identified, and depending on the RPMs the unit is being analyzed at, the proper amount, and location of corrective weight, can be added or removed from the rotating component. All assemblies repaired at our facility are balanced to within NEMA specifications for the RPM rating of the unit. Specific customer balance specifications are welcome, and Tram will accommodate any special requirements. Special precision balancing is performed routinely on these apparatuses.

COMPUTERIZED DYNAMIC BALANCING

RETURN TO REPAIR SERVICES

At Tram, we utilize three models of dynamic balancing equipment that were manufactured by the Industrial Engineering and Machine Co. of Atlanta, Georgia (IEM). Dyna-Bal is the brand name. The first unit is rated to balance a 2500 lb. rotating mass. The second can balance a mass of up to 10,000 lbs., while the third will safely balance a 15000 lb. rotating mass. Our balancing machines are designed to indicate pure static, pure dynamic, or any combination of these. The question of precision balance is entirely controlled by the work piece, condition of journals, and deflection or whip condition on flexible type rotors. It is just as easy to affect complete balance down to a few micro inches, as it is to do a rough commercial balancing job. As long as the journals or bearings of the work piece are properly finished and the piece is free from whip or deflection, this equipment is capable of extreme sensitivity, down to 0.000002 inches.

 

 

With some understanding of vibration analysis, and use of

these principles, we can balance a rotating apparatus in our     facility before assembly of the repaired unit. All rotational components of a given piece of equipment are installed on the shaft in their respective positions and balancing is performed.  “Dynamic Balancing” is balancing which is performed with the unit rotating at rated speed or at some harmonic of the unit’s rated speed. Unlike “Static Balancing,” which relies upon the heaviest side of mass to turn down with gravity while resting on an anti-friction rotating weigh, Dynamic balancing can produce an actual reading of the sensing transducer and computer module, and pinpoint the exact location of the mass displacement.
