02-10: Avoiding Cooling Tower Catastrophe Fans & Associated Equipment For designated seismic system equipment

For designated seismic system equipment that must remain operable following an earthquake

ranging from desalination to power generation

Vibrations levels in the region of the natural frequency are empirically determined for composite drive shafts and multiple test methods for determining the natural frequency are described and compared

It also shows the dramatic effect that mounting has on commonly used high frequency measurements such as Spike Energy and PeakVue that are used for early warning of bearing and gear faults

02-10: Avoiding Cooling Tower Catastrophe Fans & Associated Equipment For designated seismic system equipmentThe three major catastrophic events on cooling towers are structural failure, fan failure, and icing damage, in that order. This paper describes in detail the causative factors, methods of detection prior to event, workable preventative solutions, and solutions after the event, on all three types of catastrophes. The author has been personally involved in these type failures on multiple occasions over the past years.
