摘要： PURPOSE:To alleviate thermal stress appearing on the surface of a pump shaft by providing a heat conductive cylinder at the lower part of the labyrinth seal of a casing cover for enclosing the pump shaft, and gradually heating and raising the temperature of cooling water flowing down within the heat conductive cylinder via the labyrinth seal by means of recirculation water flowing along the external surface of the heat conductive cylinder. CONSTITUTION:Cooling water 10 flows along the external surface of a mechanical seat 7 for the cooling thereof, and returns to the mechanical seat 7 via a heat exchanger 8. Also, a portion of the cooling water 10 passes a labyrinth seal 6 and flows down within a heat conductive cylinder 9 for preventing the leakage of recirculation water 11. In this case, the cooling water 10 in the heat conductive cylinder 9 is gradually heated and the temperature thereof gradually rises in the course of flowing down in the heat conductive cylinder 9, due to the recirculation water 11 flowing along the external surface of the heat conductive cylinder 9. Also, the temperature of the cooling water 10 becomes approximately equal to the temperature of the recirculation water 11 at a position near the outlet of the heat conductive cylinder 9, and a temperature difference from the recirculation water 11 is reduced. Furthermore, a temperature change in the labyrinth seal 6 and heat conductive cylinder 9 becomes small. Consequently, thermal stress appearing on the surface of a pump shaft 4 is alleviated, and the occurrence of a crack due to thermal fatigue can be prevented.

摘要： PURPOSE:To sharply improve reliability in terms of structural strength by locating a labyrinth part on the inner surface of a casing cover positioned in a portion to divide a lower casing connected to the lower end of an upper casing. CONSTITUTION:Through rotation of a pump shaft 2, a speed gradient is produced in a microgap 21, and a temperature part having low distribution of a specified temperature is provided in a peripheral direction. Even when an amount of injected shaft seal water is low, no forced injection force generated through rotation of the pump shaft 2 is produced, and shaft seal water enters below and smoothly flows in by an amount by which the shaft seal water is pressed in. Namely, shaft seal water of cold water slowly flows in along a labyrinth part 20 located to a casing cover 14 on the static side. This constitution relaxes the change in temperature of the structural material of the labyrinth part 20 responding to a change in an inflow rate and a change in temperature, and reduces a thermal stress generated at the structural material to improve reliability.
