摘要： A method for determining the fatigue of the pump rotor of a gas turbopump comprises the following method steps: continuous determination of the rotational speed (n) of the pump rotor, determination of the local rotational speed maxima and minima of a temporal rotational speed profile under consideration, association of the rotational speed maxima and minima with each other to form pairs, determination of a pair fatigue value (L) for each of the rotational speed pairs, and accumulation of all pair fatigue values (L) to form a total fatigue value (Ltot). In this manner it is possible to determine the cyclic stress for the pump rotor of a vacuum pump and to include it in the calculation of a total fatigue value.

摘要： A turbomolecular pump (10) comprises a stator (12, 18), a pump rotor (20) a motor (28) for driving the pump rotor and a control device (42). The control device (42) controls the motor output power such that the motor output power does not exceed a permissible maximum motor output power. On the stator side of the turbomolecular pump (10), temperature sensors (32–38) for measuring the stator temperature are arranged. The control device (42) comprises a maximum output power detecting device (50) that determines the permissible maximum motor output power in dependence on the measured stator temperature. Thus, the permissible maximum motor output power is not set to a constant value but always fixed in dependence on the current, measured stator temperature. Thereby, the capacity of the motor can be fully utilized as long as the measured stator temperature lies below a maximum value.

摘要： A friction vacuum pump (10) comprises a housing (12) defining a vaneless pump stator (30), a rotor drive and a rotor support which rotatably supports a pump rotor (16) provided with a vane (18). The housing (12) surrounds the overall axial length of the pump rotor (16), the rotor drive and the rotor support. Prior art housings are of multipart configuration and thus comprise seals between the housing portions. The seals are difficult to coat and may be or become locations where leaks occur. In contrast, the housing (12) is of one-piece configuration such that, in any case, the region of the housing (12) which is in contact with the vacuum gas is free of seals.

摘要： A device (1), for evacuating a chamber to pressures in the high vacuum range includes a suction-side vacuum pump (2) and an atmospheric-pressure-side vacuum pump (3). The suction-side vacuum pump (2) is a mechanical kinetic vacuum pump with a rotor (11) and a stator (10). The stator (10) has a rotationally-symmetrical inner surface which matches the outer rotor geometry. The rotor (11) in the mechanical kinetic vacuum pump (2) is provided with a structure (13) carrying out the gas pumping. Said gas pumping structure comprises webs (14), the angle and width of which decrease from the suction side to the pressure side. The gas throughflow is improved. The outer diameter of the rotor (11) and the inner diameter of the stator (10) of the suctnion-side pump decrease from the suction side to the pressure side.

摘要： The present invention relates to a connection fitting for the connection of a ring with at least one consumer to a storey or rising main branch with inlet and outlet openings (2, 4) which can be connected to the branch and an intervening merge opening (34) for the ring main which is preceded in the flow direction (S) by a cross-section constriction (16). The present invention also relates to a water pipe system with at least one storey or rising main branch to which several ring mains are connected via separation and merge openings and a cross-section constriction provided between the separation and merge openings of the assigned ring main in the branch. The object of the present invention is to specify a connection fitting which leads to improved flow characteristics in the region of the ring main assigned to the connection fitting and to provide a water pipe system which fulfils the practical requirements in an improved manner. With this invention the object is solved by suggesting a connection fitting and a water pipe system of the prior known type, which are characterised in that they comprise means (12, 28) for varying the passage area of the cross-section constriction (V).
