Generator vibration isolators

Generator vibration isolators can use elastomeric, spring, wire-rope or pneumatic elements, depending on the installation. These constructions have different load, movement and maintenance requirements. The choice should follow the generator’s support conditions rather than a general claim that one type suits every machine.

Define the weight at each support, operating speed range and acceptable movement. Compare the isolator’s load-deflection behavior and the space available for motion. Poorly matched isolation can increase movement at some frequencies, so a blanket efficiency figure is not a substitute for selecting the system.

The base, fixings and connected services must accommodate the chosen support. Check restraints and clearances where movement is limited, and maintain any pressure supply required by a pneumatic design. Evaluate vibration at specified points on the completed installation; vibration isolation and electrical insulation describe different functions.
