As there is some height between the generator and the fixed cold water tank, a vacuum is formed in the stator bar. If the water is suddenly turned off, the water in that section of the pipe will form a vacuum in the. stator bar under the action of gravity, and the water inside will be quickly discharged. In order to keep as much water in the stator bar as possible. So install an anti-siphon pipe.
When the water is suddenly turned off, the water in the pipe is affected by gravity, causing the water pressure in the stator bar to drop below the saturation pressure, forming vaporization, causing vapor lock, and the flow of cooling water is affected. The temperature of the stator winding increases, causing it to be damaged.
Therefore, there is a hose on the jellyfish return pipe connected to the fixed cold water tank to prevent the pressure from dropping too low.
Must be less than 2.5%. The generator stator cooling water is regulated. The hydrogen content standard should be less than 2.5%, otherwise it will affect normal use. This machine refers to a mechanical device that converts other forms of energy into electrical energy. steam turbine, diesel engine or other mechanical drive.
