A major noise source on an engine production line was this camshaft washer drying station. Post cleaning, pneumatic nozzles were used to dry the camshafts. Instead of converting the existing enclosure into an acoustically effective unit, we determined that the pneumatic nozzles used were both very noisy and inefficient.
After performance testing, we recommended replacing the air-jets with carefully designed, high efficiency entraining nozzles . The results were very gratifying:
- 12dB(A) noise reduction at source
- Drying cycle time reduced by around 20%
- Air consumption reduced by 20%
This process was not only much lower cost than the previously considered enclosure, but it also rendered the noise control project carbon negative and profitably self-financing. A win-win-win noise control project.
