摘要： PROBLEM TO BE SOLVED: To provide a temperature fluctuation prevention structure at a rotational field capable of preventing thermal fatigue cracking due to temperature fluctuations at a thermal boundary layer formed by colliding high temperature water with low temperature water like a primary coolant pump of an atomic reactor plant.
SOLUTION: The thermal fatigue cracking due to the temperature fluctuations is proved to depend on the cycle of the temperature fluctuations. Therefore, the temperature fluctuation prevention structure has a cycle increase means constituted by increasing the number of keys 30 so as to increase protrusions for increasing the cycle of the temperature fluctuation around a main shaft 4 and a labyrinth 16 which form the thermal boundary layer by colliding hot primary coolant flowing into a chamber 20 through a gap 14 for circulating with cold sealing water flowing down to the chamber 20 through a gap 18.

摘要： PROBLEM TO BE SOLVED: To provide a shaft sealing device for a high-temperature water pump capable of enhancing greatly the one-way direction sealing performance.
SOLUTION: The shaft sealing device of the high-temperature water pump includes a seal element 2 or 5-j, in particular 5-3, installed in the peripheral area of a rotary shaft 1 and to seal the axial direction flow of high-temperature water and is structured so that a cooling water is passed through against the flow of the high-temperature water flowing in the counter-flow axial direction upon passing through a ring-shaped gap formed between the inside surface of the seal element 5-3 and the rotary shaft. The seal element 5-3 has a sealing surface confronting in the radial direction to the inside surface and composed of a first sealing surface 7-3 formed in the downstream and a second sealing surface 6-3 formed upstream in the regular flow axial direction. The second sealing surface 6-3 is formed as a slope to squeeze the flow of the cooling water flowing in the regular flow axial direction. In the squeezing region formed between the second sealing surface 6-3 and the peripheral surface of the rotary shaft, the flow of the cooling water in regular direction flow confronts vigorously to the counter-flow of the high-temperature water, and the flow passage section area of the squeezing region is small and the volume of the region in which a temperature fluctuation is generated, is small. The prevention of the counter-flow and a decrease in volume relieve the temperature fluctuating phenomenon synergetically, and the one-way direction sealing performance is enhanced greatly.
