Visco-Elastic Support (VES)

Product catalog summary

Introduction
Hydroelectricity is a highly efficient form of renewable energy, but hydropower plants often face issues with high-frequency vibrations in hydro-electric generators. These vibrations can cause significant damage to the generator and surrounding structures.

Visco-Elastic Support (VES) Overview
ITT Enidine has developed the Visco-Elastic Support (VES) product line to address these issues. VES improves the dynamic behavior of the rotor-bearing system and reduces thermal forces on bearing support structures. It provides high dynamic stiffness, supplementary damping, and low static stiffness, which reduces the generator's dynamic response and prevents excessive thermal force transfer to civil structures. This extends the life of the generator and structure while increasing power plant efficiency.

Technical Specifications
The VES product line includes models VES100A, VES150A, VES200A, and VES250A, each with specific technical parameters such as total stroke, preload at set point, nominal damping constant, maximum force, dynamic stiffness, and static stiffness. The flange dimensions for each model are also specified.

Customization and Contact Information
Enidine offers custom design services to meet specific application needs. Contact information is provided for further inquiries and custom design requests.

Catalog excerpts

Renewable Energy Through Product Innovation One of the most efficient forms of renewable energy is hydro-electricity. A typical hydropower plant will produce electricity by the use of hydro-electric generators. Problems often arise with these generators over time due to high frequency vibrations excited by periodic and stochastic forces originating in the hydraulic machines and generator. Usually the vibration peaks out at the guiding bearing above the generator rotor, causing substantial damage to the generator and surrounding structure. ITT Enidine has developed the new Visco-Elastic Support...
