ASME Buffalo Section – Vibrations / Balancing of Hydroelectric Generators

April 16 @ 5:30 pm - 7:30 pm

ASME Buffalo Section Joint Program Announcement
1 PDH Program (approval pending)

Vibrations / Balancing of Hydroelectric Generators

Date:  Tuesday April 16, 2019 

Location: Niagara Power Vista, 5777 Lewiston Road, Lewiston, NY, 14092

Time: 5:30 pm

Presenter:  Eustace A. Mendez, Principal Project Engineer, New York Power Authority

Tour Abstract:  Excessive vibration in machines is caused by imbalance of the rotor (the rotating component of a motor). At power plants, employees tasked with maintaining the generators must field balance the rotors after rebuilding the units, following maintenance outages and, in cases where the machine has deteriorated during operations to the point that it experiences excessive vibrations due to dynamic unbalance. Vibration  subjects bearings to very high loads which may lead to fatigue failure. Excessive vibration can also be caused by other factors such as electrical unbalance or pull, shaft or coupling issues, rubbing of rotating elements, and cavitation around the turbine wheel. To optimize the process of balancing the units, each of these factors must be taken into account, so that generators may be efficiently and successfully run at various speeds and loads.

Dinner Choices:   Dinner will be provided.  Details will be posted as soon as available.

Cost:  ASME Members $25, Non Members $30, students $15
