The utility model provides a high-pressure wear-resistant centrifugal
steam turbine impeller, which relates to the technical field of
steam turbine impellers, and comprises a connecting shaft, fan blades, a limiting piece, a mounting plate, a connecting shaft, a connecting shaft, a connecting shaft, a connecting shaft, a connecting shaft, a connecting shaft, a connecting shaft and a connecting shaft, and is characterized in that the limiting piece is arranged outside the fan blades and is used for connecting and limiting the fan blades; the fixing ring is fixedly arranged on the outer sides of the ends of the multiple fan blades, the mounting piece is arranged in the mounting plate, the limiting block is fixedly arranged on the inner side of the mounting plate, and the ends of the fan blades are fixed through the fixing ring and a multi-stage limiting structure of the connecting ring and the limiting plate. Compared with the prior art, the vibration trend of the fan blades under the action of
wind power in operation can be effectively limited, it is ensured that the positions of the fan blades are relatively static, the
vibration amplitude is greatly reduced, the phenomena of friction,
collision frequency and
stress concentration between the fan blades and
peripheral components are remarkably reduced through vibration reduction, and
material fatigue, abrasion and structure looseness caused by high-frequency vibration are avoided.
