囲は気泡がないから水中モータが気泡腐食されない。(Function) As described above, when the submersible motor rotates, the water between both bulkhead plates and the vane plate moves toward the outer circumference by the blade plates of the rotating body, and as a result, negative pressure is created between the two bulkhead plates. Air flows out from the opening of the air supply passage, the air is agitated with water by the rotation of the blade plate, mixes between both partition plates and the blade plate, moves toward the outer circumference, and because of the shade member, the air supply pipe etc. The resistance prevents the air from blowing out in one direction, and the water mixed with air is uniformly spread over a wide area from the lower outer periphery of the cap member to the outside in all directions, resulting in gas-liquid mixing over a wide area. are done evenly. New water flows out around the rotating body from the communication hole on the center side of the shade member, and since there are no bubbles around the submerged motor, the submerged motor will not suffer from bubble corrosion.

・The first and second partition plates 2c and 2 are rotated by rotation of 4c and 4d.
The water between d and the vane plates 4a, 4b, 4c, and 4d moves toward the outer circumference, and therefore, the area around the shaft body 2a between the first and second partition plates 2c and 2d becomes negative pressure, and air is supplied. Air flows out from the passage 13, is agitated by the rotation of the blade plates 4a, 4b, 4C, and 4d, and is mixed with the first and second partition plates 2C, 2d and the blade plate 4.
Air mixes with water between a, 4b, 4C, and 4d, and the outer periphery of the second partition plate 2d at an angle β from the outer periphery of the first partition plate 2c of the vane plates 4a, 4b, 4c, and 4d. The water around the rotating body 2 is strongly agitated by the protruding part,
The first and second partition plates 2C-26 and the blade plates 4a, 4b,
The water and air mixed between 4c and 4d are released to the outer periphery and are strongly agitated with the water, and the air is divided into fine particles and mixed into the water. 1
The second resistance prevents the air from blowing out in one direction, and the water mixed with air is evenly spread over a wide area by being pushed outward in all directions from the lower outer periphery of the shade member. New water flows out from the central communication hole of the cap member, mixes with air, and forms a flow that spreads outward widely and evenly.The air bubbles pushed outward move upwards due to buoyancy, so they are near the underwater motor l. Since there are no air bubbles, the outer wall of the underwater motor will not be corroded by air bubbles.
この際、羽根板４ａ・４ｂ・４Ｃ・４ｄが角度α傾斜し
て設けであるため外方へ放出される水流が下方へ押し下
げられ、空気の浮力に対抗して笠部材ｌＯの下を外方へ
向って容易に通過する。At this time, since the slats 4a, 4b, 4C, and 4d are inclined at an angle α, the water flow released outward is pushed downward, counteracting the buoyancy of the air and flowing outward under the shade member IO. easily pass through.
