| Abstract: | Application of the ski-jump method achieves remarkable results for decreasing the siltwear of mixed flow turbine. This method is to weld some radial steel plate with suitable intervaland height on the internal surface of front cover or top cap of turbine which is the easiest wearedparts and the siltladen flow is jumped away from the intemal surface of front cover for decreasingwear.Also the bush can be installed in front cover or top cap as the wear is serious and the ski-jump plates are welded on the bush. |
