の冷却を行う。 On the other hand, in a Pelton turbine, the inside of the housing becomes negative pressure due to the rotation of the runner and the jet from the nozzle during operation of the turbine, so as a measure to prevent this, air is supplied from the atmosphere outside the turbine pit. This device is constructed by connecting an air supply pipe to an air supply port provided in a housing, and extending the tip of this air supply pipe to the vicinity of the turbine runner and nozzle of the Pelton turbine. Then, air is sucked into the housing by the rotation of the runner and the suction action caused by jet water jetting from the nozzle, and the air flow at this time is applied to the radiator to cool the lubricating oil.

The main shaft 4 is directly connected to a generator (not shown). Then, the runner 1 and the main shaft 4 are
rotates. Further, an air supply pipe 6 communicating between the inside of the housing 2 and the air supply hole 7, and an air supply pipe 6' branched from this air supply pipe 6 and connected to the runner 1 are provided on the wall of the water turbine pit 10. Each tip of 6' extends to the vicinity of nozzle 5 and runner 1, respectively. A radiator 8 is provided in front of the air supply hole 7. A circulating oil pipe 9 is connected between the heat radiator 8 and the main bearing 3.

３と放熱器８の間を循環する冷却油を冷却する。 In this embodiment configured in this way, when the runner 1 rotates due to the injection of jet from the nozzle 5 during operation of the water turbine, the pressure inside the housing 2 decreases, so that the pressure between the housing 2 and the air supply hole 7 decreases. A pressure difference is created, which causes air to flow from the air supply hole 7 through the air supply pipe 6 into the housing 2 . On this occasion,
Since the tips of the air supply pipes 6 and 6' extend close to the nozzle 5 and the runner 1, respectively, the nozzle 5
The suction action of the runner 1 acts directly on the air supply pipe, increasing the amount of air supplied from the air supply port. Therefore, wind is generated before and after the radiator 8, which has a cooling effect on the radiator 8, and cools the cooling oil circulating between the main bearing 3 and the radiator 8 through the oil circulating pipe 9. do.

Since the movement of air uses the air supply action of the Pelton water wheel, everything is done automatically, so there is no need for water supply pumps or air compressors that use on-site power, simplifying auxiliary equipment. This has the advantage of saving power on the premises.
