Fitness for service self-tube bushings in hydropower applications
- Powertech Labs., Inc., Surrey (Canada)
- Army Corps of Engineers, Portland, OR (United States); and others
A rigorous test program was undertaken to evaluate the performance of self-lubricating bushings from various manufacturers for applications as wicket gate bushings. The program consisted of a mechanical test simulating field conditions in the laboratory and a material analysis program to identify and quantify the materials present in each bushing and assess the suitability of the chosen bushing materials for the application. An original program for B.C. Hydro established a comparison of nine self-lubricating bushing products based upon coefficients of friction and wear rates. The evaluation program was expanded and modified with support from the U.S. Corps of Engineers with a view to identifying additional products suitable for this hydropower service.
