    摘要： A centrifugal compressor includes: a rotor having a shaft extending along an axis and an impeller that is fixed to an outer surface of the shaft and feeds a fluid, which flows into a first side in an axial direction, to an outer side in a radial direction of the axis under pressure; a diaphragm surrounding the impeller from an outer circumference side; a first casing head disposed at a second side of the diaphragm in the axial direction at an interval; a seal device disposed between the first casing head and the shaft; a bearing device disposed at the second side in the axial direction with respect to the seal device and disposed between the first casing head and the shaft; and a shield part fixed to a first side of the first casing head in the axial direction and configured to define a suction flow passage for introducing fluid into the impeller along with the diaphragm and to define an insulating space between the shield part and the first casing head.

    摘要： A fan section (22) includes a fan inlet case (110), a fan bearing assembly (120), and an annular heatshield (130). The fan bearing assembly (120) is coupled to the fan inlet case (110) and the annular heatshield (130) is mounted to the fan inlet case (110). The annular heatshield (130) is configured to reduce convective heat transfer from heated fluid to the fan bearing assembly (120). A method of heating the fan section comprises flowing the heated fluid through a plenum chamber (132) formed by a radially inward surface of the fan inlet case and the annular heatshield.

    摘要： Provided is an outlet port part capable of efficiently increasing the temperature of an entire outlet port of a vacuum pump in which the outlet port part is disposed, and the vacuum pump provided with this outlet port part. The outlet port part according to an embodiment of the present invention has a heat insulating portion for preventing heat obtained from a heater disposed in the outlet port part from being transmitted toward a base side, and for transmitting the heat efficiently to the back (the vacuum pump side) of the outlet port. Further, the vacuum pump according to the embodiment of the present invention has the outlet port part having the heat insulating portion. The heat insulating portion of the outlet port part according to the embodiment is provided with a flange portion formed on the outer peripheral surface of the outlet port part, and a heat insulating spacer disposed in close contact with the flange portion. Alternatively, an outlet port part flange portion that is configured by integrating the flange portion formed on the outer peripheral surface of the outlet port part and the foregoing heat insulating spacer functions as the heat insulating portion. This configuration can efficiently increase the temperature of the entire outlet port of the vacuum pump, thereby reducing the amount of product and deposit.
