How to Reduce Vibration in Generators and Compressors

Introduction

Vibration in generators and compressors is a critical concern during operations. Undamped vibrations can lead to equipment dislocation, damage, noise pollution, increased operational cost and reducing machine life. Effective vibration control ensures operational efficiency, equipment longevity, and safety.

One of the most effective methods for mitigating vibration is the use of Rubber/ Spring Mounting. These components act as vibration absorber and dampening oscillations generated during machine operation. By interrupting the transmission path of vibrational energy, rubber mountings protect both the equipment and its supporting structures.

In this context, Resistoflex offers a range of specialized Rubber/ Spring Mounting designed to address the specific vibration challenges associated with generators and compressors. Their products, including Flexifloat, Genflex, Mobiflex, Coniflex, and Open Spring Damper 2, are engineered to provide optimal vibration isolation in various industrial applications Specially in compressors and generators. This blog explores how each of these solutions contributes to vibration reduction and improved equipment performance.

   The conical design allows it to accommodate both radial and axial loads effectively, making it ideal for equipment where vibrations are not confined to a single axis.

5. OSD-2 (Open Spring Damper-2)

   For applications that demand both isolation and structural stability, the OSD-2 offers a hybrid solution by combining spring elements with rubber damping. It delivers high deflection and low natural frequency, making it ideal for isolating low-frequency vibrations in large systems.
   
   Applications: Large gensets, chillers, HVAC systems, industrial compressors
   
   Key Benefits:
   • Dual isolation mechanism (spring + rubber)
   • Low natural frequency for better damping
   • Rugged steel frame for durability
   This product is particularly effective where vibration amplitudes are significant and where both load capacity and high isolation efficiency are needed.

Why Rubber Mountings Are Essential for Vibration Control

Excessive vibrational activity in industrial application systems directly compromises operational reliability, accelerates wear and fatigue, and increases the total cost of ownership. Here's why Rubber/ Spring Mounting are the preferred solution:

• Structural Vibration Energy Absorption: Rubber compounds exhibit high damping characteristics, enabling them to effectively absorb vibrational energy and convert it into thermal energy through internal friction and viscoelastic deformation.


• Noise Reduction: Mitigates the transmission of structure-borne vibrations, thereby enhancing the overall acoustic isolation and sound attenuation performance of the built environment.


• Longevity: Reduces wear and tear on components, extending equipment life.


• Versatility: Available in various configurations to match load and frequency requirements.
