Abstract
The utility model discloses a high-temperature rotor water circulating cooling device for excitation rotor cooling, which comprises a stator and a rotor. The rotor comprises a rotor body. One end of the rotor body is provided with an extension segment. A water storage chamber is arranged on the extension segment. A water pipe passes through the water storage chamber of the extension segment from a central axis outside the stator and then enters the rotor body. A water inlet is arranged on the water pipe located on the outer side part of the stator. A circulating water flow passage for making the water storage chamber and the water pipe communicated is arranged inside the rotor body. The side wall of the extension segment is provided with a water outlet of the water storage chamber. A water outlet channel for discharging the water inside the water storage chamber out of the stator is arranged on a part corresponding to the water outlet. By adopting the above-mentioned structure, the high-temperature rotor water circulating cooling device is enabled to take away the heat generated by the high-speed rotation of the rotor through cooling water inside the circulating water flow passage and well make the rotor cooled. The long-term use of the rotor is then benefited. In particular, the power failure phenomena generated by a damaged rotor due to high temperature in a piece of power generation equipment are eliminated. Great convenience is thus brought to people.
