Abstract

The invention proposes a ventilation structure for small and medium vertical turbine generators, and the structure is characterized in that the structure comprises a turbine generator main shaft, a plurality of magnet yoke blocks, a lower fan cover, an upper fan cover, ventilation slotted vanes and a support column. The plurality of magnet yoke blocks are disposed on the turbine generator main shaft in a sleeving manner after processing, and the upper edges of the magnet yoke blocks are uniformly provided with vent holes along the center. The vent holes are through vertically, and the adjacentmagnet yoke blocks are connected through the ventilation slotted vanes and the support column. The upper fan cover is disposed on the vent hole of the magnet yoke block above the turbine generator main shaft, and the lower fan cover is disposed on the vent hole of the magnet yoke block below the turbine generator main shaft. The upper fan cover and the lower fan cover are located outside the magnet yoke blocks. The structure is suitable for the small and medium vertical turbine generators which are small in size and higher in speed. The structure is simple, the processing burden is small, andthe installation is convenient.

Description

technical field [0001] The invention relates to the technical field of water turbines, in particular to a ventilation structure for medium and small vertical water turbine generators. Background technique [0002] In the prior art, the ventilation of large-scale vertical hydro-generators is generally in the form of laminated yokes with ventilation grooves reserved in the middle. However, the integral yoke used in small generators is a forged integral structure of the yoke and the rotating shaft, without radial ventilation, which cannot meet the requirement of taking away the heat loss of the unit. [0003] Therefore, the present invention designs a ventilation structure suitable for medium and small vertical hydroelectric generators, which is suitable for small and medium hydroelectric generators with small structural size and high rotating speed, and has the advantages of simple structure, small amount of processing, and convenient installation. Effectively ensure ventilat...
