Visco-Elastic Support (VES Series)

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 enhance the dynamic behavior of rotor-bearing systems and reduce thermal forces on bearing support structures. VES 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 innovation extends the life of generators and structures while increasing power plant efficiency.

Technical Specifications
The VES product line includes models such as VES100A, VES150A, VES200A, and VES250A, each with specific technical parameters:

VES100A: Total Stroke: 8 mm, Preload at Set Point: 3 mm, Maximum Force: 100 kN, Dynamic Stiffness: 900 kN/mm, Static Stiffness: 20.0 kN/mm.
VES150A: Total Stroke: 8 mm, Preload at Set Point: 4 mm, Maximum Force: 150 kN, Dynamic Stiffness: 1269 kN/mm, Static Stiffness: 28.0 kN/mm.
VES200A: Total Stroke: 8 mm, Preload at Set Point: 3 mm, Maximum Force: 200 kN, Dynamic Stiffness: 1100 kN/mm, Static Stiffness: 30.0 kN/mm.
VES250A: Total Stroke: 8 mm, Preload at Set Point: 3 mm, Maximum Force: 250 kN, Dynamic Stiffness: 1425 kN/mm, Static Stiffness: 33.0 kN/mm.

Catalog excerpts

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 (VES) product line to provide improved dynamic...
