摘要： A turbomolecular pump has a rotor element in a housing. The rotor element is arranged on a rotor shaft. The rotor shaft is supported by two bearing elements in the housing. The bearing element on the high-vacuum side is constructed as a roller bearing. In order to guarantee a pressure in the area of the bearing element that is acceptable for the bearing element constructed as a roller bearing, the bearing element is arranged in a chamber. The chamber is connected via a channel to the pre-vacuum area and sealed relative to the high-vacuum area by a gasket.

摘要： A vacuum pump system comprises two vacuum pumps which are connected to each other. In order to create vacuum pump system of a more compact size, the connection between the two vacuum pumps is performed via connection elements directly attached to the pump housing and forming connection sites, and the outlet flange of the upper pump is placed directly on the inlet flange of the lower pump without thereby causing a transmission of larger forces or moments.

摘要： The vacuum pump comprises a casing (10) closed by a vacuum cover (20). Between an end wall (14) of the casing (10) and the vacuum cover (20), a circuit board (16) is arranged for current feedthrough. The circuit board (16) is sealed by two sealing elements (15, 21) of different diameters so that an annular partial region (22) is on its outer side subjected to the atmospheric pressure and is on its inner side subjected to the vacuum. It is avoided that the circuit board (16) laterally projects beyond the contour of the casing (10).

摘要： Into a vacuum pump device arranged for suctional intake of a process gas (38) possibly comprising reactive particles (40), oxygen in the form of air or pure oxygen is supplied in a controlled manner via an oxygen intake (26, 26a,26b). Thus, controlled oxidation takes place in the compression chamber (24) such that the dust cannot self-ignite in case of sudden ventilation.

摘要： In a method for determining a statement of a state of a turbomolecular pump, and in a turbomolecular pump, a vibration curve is determined with a vibration sensor (10) connected to the turbomolecular pump. The determined vibration curve is transferred to an evaluation device (12), wherein vibration amplitudes are detected by a filter (16) in the evaluation device (12) and then compared to comparative values. If a threshold value is exceeded, a warning signal is transferred to a monitoring system (30) by a remote data transfer device (28). The method allows for online monitoring of turbomolecular pumps.
