Spring Elements and Spring Damper Elements: Reducing Vibrations in Industrial Applications

In industrial machinery and applications, reducing vibrations is crucial for optimal performance and minimizing potential damage. Certain machines generate vibrations during operation, while others are highly sensitive to vibrations from their environment. To address these challenges, the use of spring elements and spring damper elements provides tailored solutions for vibration isolation. Let’s explore the applications, operating principles, and product features of these elements in industrial settings.

Spring elements find applications in various scenarios, including the vibration-isolated installation of machinery in power plants (e.g., turbines, pumps, blowers, coal mills) and large machines such as presses, forging hammers, and crushers. These elements can also be utilized for vibration isolation in buildings or precision machinery, protecting sensitive equipment from environmental vibrations.

By employing vibration isolation through spring elements, the transmission of dynamic loads between machines and their foundations is significantly reduced. Source isolation effectively decreases vibrations generated by crushers or presses, while receiver isolation safeguards sensitive measuring and production machines from vibrations in the surrounding environment.

LISEGA Product Features:
