IPC: F04D7/06
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent the thermal fatigue failure of a structural member caused by the fluctuation of temperature, by installing a fluctuation of temperature preventing member which faces into a chamber comprising a boundary part of a high temperature liquid and a cooling water, inside of a shell member, and reducing a circulation speed of the high temperature liquid in the chamber. SOLUTION: When a rotary disc 2 fixed to a shaft 1, is rotated in a chamber 4, by the operation of a high temperature liquid pump, the high temperature water flows from a lower chamber 4b into an upper chamber 4b as shown by an arrow Z, and is circulated in the upper chamber 4a by the rotation of the rotary disc 2. On the other hand, the cooling water is flown as shown by an arrow Y, for cooling the shaft 1 and a bearing 5, and then is entered into the chamber 4. A fluctuation of temperature preventing ring 8 is installed near the boundary part of the high temperature water in the upper chamber 4a and the cooling water.  The circulation speed of the circulated high temperature water is reduced by the prevention ring 8, so that the speed difference between the circulation speed of the high temperature water and the speed at the cooling water side, is reduced, which inhibits the disorder of the boundary part, and prevents the generation of the fluctuation of temperature.
