    摘要: Ein Vakuumgerät, insbesondere eine Vakuumpumpe, umfasst einen schmiermittelfreien Raum und einen ein Schmiermittel enthaltenden Raum sowie eine drehbar gelagerte Welle, die zumindest abschnittsweise in den beiden Räumen angeordnet ist. Zwischen den Räumen ist eine Dichtvorrichtung vorgesehen, durch welche die Welle hindurchtritt und welche ein Rotorelement, das mit der Welle drehfest verbunden ist, und ein Statorelement umfasst, das drehfest zwischen den Räumen angeordnet ist. Zwischen dem ersten Statorelement und dem Rotorelement ist ein erster Spalt mit einer Eintrittsöffnung gebildet, welche zu dem das Schmiermittel enthaltenden Raum offen ist. Der erste Spalt weist gegenüberliegend zu der Eintrittsöffnung eine Austrittsöffnung auf, die mit einem Expansionsraum verbunden ist. Der Expansionsraum weist eine größere Querschnittsfläche als der erste Spalt auf und ist durch Wandabschnitte des Rotorelements und des Statorelements gebildet. Der Expansionsraum steht mit einem Schmiermittelsumpf in Verbindung.

    摘要: An object is to provide a multi-stage electric centrifugal compressor including an electric motor and free from risk of breakdown of an operation control part due to heat generated by low-pressure stage and high-pressure stage compressors. A multi-stage electric centrifugal compressor includes: an electric motor; a pair of centrifugal compressors coupled to either side of the electric motor, the pair of centrifugal compressors comprising a low-pressure stage compressor and a high-pressure stage compressor connected in series; a heat-shielding plate disposed between an end portion on a low-pressure-stage-compressor side of the electric motor and an end portion on a motor-housing side of the low-pressure stage compressor, and configured to shield heat generated by the low-pressure stage compressor; and a bending portion disposed in middle of the heat-shielding plate, and extending along a rotational shaft of the electric motor so as to surround an outer periphery of the rotational shaft. An inner surface of the bending portion faces the rotational shaft via a clearance part, and the bending portion functions as a shaft sealing portion which prevents leakage of intake air from the low-pressure stage compressor.

    摘要: A seal mechanism (20A) is disposed on an outer circumferential side of a rotor (2) extending along an axis (O) to perform sealing between the seal mechanism and the outer circumferential surface (2a) of the rotor (2). The seal mechanism (20A) includes a main body portion (21A) having a cylindrical shape, and into which the rotor (2) is inserted; and a plurality of hole portions (22) formed on an inner circumferential surface of the main body portion (21A) to face an outer circumferential surface of the rotor (2). The hole portions (22) are within a range in which a hole depth h is equal to or smaller than a hole diameter d.
