Reconstruction of Turbine Equipment at Hydroelectric Stations


Thus, taking the following measures can be recommended for effective solution of the problem of preventing fouling of generator parts with oil:
  1. 1.

    The enlistment of skilled specialists for evaluating the design of the installed seals from the viewpoint of current information about the distribution of air streams in the generator.

  2. 2.

    Inspection of the seals of oil baths, determination of the places of leaks through existing loose fits, bolts, flange connections, etc.

  3. 3.

    Conduction of tests for determining maximum vacuum zones and for a comparative analysis of pressures in and outside an oil bath.

  4. 4.

    The development of an active protection system with withdrawal of oil vapors into the maximum vacuum zone to prevent steaming.
