Embodiment Construction
[0020] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] Depend on Figure 1-6 Given, a hydrogen sealing device for a turbogenerator set in the present invention includes a generator shaft 12 and a generator end cover 13 arranged outside the generator shaft, the generator end cover 13 is a stationary part, and the generator shaft 12 is a rotating part , the generator shaft 12 passes through the generator end cover 13 and can rotate around its axis. There is a certain gap between the two to ensure that the generator shaft 12 does not contact the generator end cover 13 when rotating. The outer side of the generator shaft 12 A seal seat 2 fixed with the generator end cover 13 is provided. The seal seat 2 is a hollow structure with an opening facing the inner side of the generator shaft. The generator shaft 12 at the opening of the seal seat 2 is covered with a Together wi...
