The invention discloses a novel control ring abrasion-resistant mechanism. The novel control ring abrasion-resistant mechanism comprises a control ring small lug plate, a large ring plate and a clamping plate. The back surface of the control ring small lug plate is reinforced with the clamping plate. The control ring small lug plate, the large ring plate and the clamping plate are provided with abrasion-resistant blocks correspondingly. Planar friction is formed between the abrasion-resistant blocks and an outer water distribution ring. The novel control ring abrasion-resistant mechanism provided by the invention is high in manufacturing precision, convenient to mount and maintain and reliable in operation and is used for a tubular turbine unit, and the problems that the distances betweensmall lug holes of tubular unit control rings cannot be ensured well during production and processing, parts such as the control rings and pressing rings are prone to being abraded during operation, and maintenance is troublesome are solved.
Description
technical field [0001] The invention relates to the technical field of water turbines, in particular to a novel control ring anti-wear mechanism. Background technique [0002] At present, there are many problems in the conventional welded control ring of tubular turbines in the process of manufacturing and power station operation. First, in the manufacturing process, the 16 small ear plates on the control ring are welded to the large ring plate. Since it is There will be welding errors. When processing the pin holes on the small ear plates, since the 16 small ear plates are distributed at intervals and have a certain angle, the error will also increase when marking the index. Another thing is that during the operation of the power station, a large number of steel balls are placed between the control ring, the pressure ring, and the outer water distribution ring, and the adjustment of the control ring to the guide vane is realized by the rolling of the steel balls. However, ...
