Hydro-electric turbo-machine |
摘要 |
In a turbo-machine having a rotor member movable relative to a stationary housing member there is provided a substantially ring-shaped or annular seal between both of these members and serves to seal pressurized water from an external space or region. One of both of these members possesses a sealing surface against which there is pressed a sealing body of the seal which is inserted into the other member, the sealing body being for instance constituted by a lip seal. Improved lubrication, reduced friction and enhanced service life of the seal is attained in that, the sealing surface has fed thereto a friction-reducing liquid, for instance by means of radial grooves provided in the sealing surface or by means of bores opening into the sealing surface.
