Abstract

The invention relates to a high-temperature pump bearing cooling auxiliary device for nuclear power, and refers to the cooling auxiliary device which is installed on a transmission shaft of a cooling oil cavity. The high-temperature pump bearing cooling auxiliary device comprises a first outer gear, a second outer gear, an inner gear, a cover plate and blades. The transmission shaft is connected with the first outer gear through a key, the first outer gear is meshed with the second outer gear which is connected with the inner gear, and therefore the blades fixed to the inner gear are drive to run at a low speed, cooling oil can flow in the cooling oil cavity, and the aim of reinforcing heat transfer is achieved.

Description

technical field [0001] The invention relates to a device for improving the cooling performance of a bearing, in particular to a heat dissipation auxiliary device for a high temperature pump bearing used in nuclear power. Background technique [0002] Nuclear power is a relatively mature clean energy that can be developed on a large scale and provide stable power output. In a nuclear power plant, whether it is a nuclear island, a conventional island or a supporting system, pumps are very important equipment. Nuclear power high temperature pumps mainly transport high-temperature and high-pressure fluids. During the operation of the pump, the heat of the high-temperature water in the pump is transferred to the bearing body of the pump, coupled with the frictional heat generated by the high-speed rotation of the bearing, the temperature rise of the bearing body is much higher than that of the pump. Its allowable operating temperature rise range, too high operating temperature w...
