  • Method for reducing hydraulic turbine seal temperature while turbine runner is rotating in air
    Patent number: 4047831
    Abstract: A method is disclosed for admitting high pressure air to the seals of a hydraulic turbine runner which is rotating in a gas such as air. The high pressure air reduces the temperature of the seal and at the same time maintains a desired air pressure in the runner casing. Means are also provided to permit evacuation of air or gas from the runner casing to reduce the pressure therein below atmospheric pressure to decrease the windage losses of the rotating runner and permit lower pressure cooling air or gas to be applied to the runner seals.

  • Hydraulic turbine draft tube pressure stabilizer
    Patent number: 4003674
    Abstract: A hydraulic turbine having means for admitting air to the turbine draft tube. An annular air chamber about the draft tube has a plurality of circumferentially spaced openings into the interior of the draft tube. The pressure of the air in the air chamber is maintained below the maximum pressure of the water in the draft tube and above the minimum pressure of the water in the draft tube. This results in air entering the draft tube only at the areas of lowest water pressure and water entering the air chamber at areas of highest water pressure.
