Bottom ring and cover wear-resistance plate of water guide mechanism of water turbine

The utility model relates to bottom ring and cover wear-resistance plate of water guide mechanism of water turbine, The upper part of the multi-block wearing plates is fixed with a top cover and the lower part of the multi-block wearing plates is fixed with a bottom ring and forms a ring. Each wearing plate comprises an inner region, a middle region and an outer region. The middle region is a removable structure and is fixed by press plates and screws. The utility model proposes the new structure of wearing plate through observing and analyzing the worn condition of the traditional structure of bottom ring and cover wear-resistance plate of water guide mechanism of water turbine. The new structure ensures the wearing plate system is always in sound condition when the generator operates through reasonably using materials, lengthening the service life of wearing plates and reducing the downtime in the maintenance and replacement of the wearing plates.
