    摘要: Provided is a vacuum pump having a stator disc having a divided structure, in which gaps or misalignments that occur between connection surfaces at which the divided structure is connected are reduced. In a turbo-molecular pump according to this embodiment, a mating relationship between a stator disc and a stator member for alignment (center-alignment) is opposite from that of the related art. Specifically, in a structure in which a base and the stator disc are fitted together, center alignment (positioning/centering) is performed through a structure in which an outer peripheral surface of the stator disc is held (restrained from an outer side) by an inner peripheral surface of the base to be connected thereto. Further, the mating structure of the stator disc includes an integral component. Moreover, the mating position of a stator blade and the mating position of the stator disc having a Siegbahn structure are provided separately.

    摘要: A molecular pump (1A) includes a pump body (2) provided with a turbo molecular pump portion (2a), a control unit (4) provided with a control portion and a power supply portion, and a cooling unit (3) for cooling the pump body (2) and the control unit (4). A first temperature detecting portion (90) is provided in a first position, which is a position inside the control unit (4) and has a low temperature. A second temperature detecting portion (80) also serving as a humidity detecting portion is provided in a second position, which is a position inside the control unit (4) and has a high temperature. The control portion controls the operation of the cooling unit (3) in accordance with a relative humidity in the first position, calculated based on temperature information detected by the first temperature detecting portion (90) and based on temperature information and humidity information detected by the second temperature detecting portion (80) also serving as a humidity detecting portion.

    摘要: [Problem to be Solved] Stator blade wheels and rotor blade wheels do not interfere with each other using lower-cost but wider cutting-width cutting or grinding for half-cutting-off of the stator blade wheels and not using expensive but narrower cutting-width wire electric discharge machining. [Solution] The distance h between a base end face 12ta (12tb) of a stator-blade-wheel outer ring part 12a and the corresponding rotor-blade end face 4aa (4ab), is set at a value larger than the maximum deformation of the running rotor blade wheel 4a during the pump operation. The larger distance h keeps perfectly stator-rotor separation, while the outer ring part 12a of a stator blade wheel 12 goes, in assembling, into the rotor area on account of large shift of any half of stator blade wheels owing to the wide cutting width. It makes also easy stator blade wheel assembling of the pump, as it is allowable to arrange half stator blade wheels with some eccentricity.
