Description du projet

Limitation of vibration amplitudes and ground forces by vibration-isolated installation of a centrifugal fan with a weight of approx. 13t. In previous elastic installation, large horizontal movements occurred during operation due to resonance in the horizontal direction. Strong corrosion of existing spring elements.

Solution

Replacement with 11 VICODA spring elements with special coating for highly corrosive medium. Vertical tuning frequency of the setup approx. 7 Hz, degree of isolation 55%. Reduction of vibrating movements due to increased horizontal rigidity.
