Zusammenfassung: | The invention belongs to the technical field of impact type hydraulic turbine sets, and particularly relates to an impact type self-adaptive main shaft sealing structure. According to the technical scheme, the impact type self-adaptive main shaft sealing structure comprises a pressing ring connected to a supporting flange of a waterproof protective cover and a sealing ring supporting base connected to a main shaft flange of a main shaft, a sealing ring is arranged in the sealing ring supporting base, and a plurality of vent holes are formed in the lower portion of the sealing ring supporting base. The upper surface of the sealing ring is matched with the lower surface of the pressing ring; a through hole is formed in the pressing ring, a sealing water pipeline communicated with the through hole is connected to the pressing ring, and the other end of the sealing water pipeline is communicated with the tail water channel. The invention provides an impact type self-adaptive main shaft sealing structure capable o |
