Manufacturing & Process
DEICON OFFERS CUSTOMIZED PASSIVE AND ACTIVE NOISE AND VIBRATION CONTROL SOLUTIONS TO SUIT THE UNIQUE DEMANDS OF INDUSTRIAL MACHINERY AND PROCESS EQUIPMENT.
DEICON offers solutions for reducing the level of what perturbs the equipment, modifying the structural or acoustical dynamics of the equipment by varying its inertia and/or compliance, isolating the equipment, and adding structural or acoustic damping to the equipment.
A sample of applications includes but are not limited to structural damping of piping systems, vibration isolation of power generators, pumps, fans, compressors, etc., and acoustical damping of combustors.
- Mitigating combustion-driven oscillation (thermoacoustic instability) in industrial combustors
- Tuned damping of a 12 inch piping system
- Lowering noise and vibration transmission of a 200 Ton screw compressor refrigeration system (chiller)
Vibration Isolation of Industrial Equipment
Transformer Noise and Vibration Abatement
When transformers are rigidly (not resiliently) mounted on the floor (or any other structure supporting them), their vibration will transmit to the support structure and find its way in neighboring spaces (rooms, offices, laboratories, etc.), causing an annoying, tiring, tonal noise. This structure-borne noise issue can be addressed by Isolating the core and coils of the transformer from the ground/floor, using proper vibration isolators. In air-cooled dry transformers, this means to isolate the core and coil from its support structure. For an oil-filled unit, it means to isolate the core and coil from its tank base and isolate its tank base from the support structure. Making certain all the connections to the surrounding are flexible. This includes incoming cables, busbars, stand-off insulators, etc. Note that any rigid connection from the vibrating transformer to a solid structure will transmit vibration. Avoiding the use of a room, to house a transformer, with dimensions corresponding to the half wavelength of the transformer vibration/noise frequencies. That is, stay clear of the room acoustic resonances being perturbed by the transformer.
