摘要： A twin-shaft pump includes a working chamber; a first side plate and an opposite, second side plate bounding the working chamber; and two impellers accommodated in the working chamber and each having a first end face and an opposite, second end face. Each first end face is adjacent and oriented toward the first side plate and each second end face is adjacent and oriented towards the second end plate. There are further provided impeller bearings adjacent the first and second end faces of each impeller; and a pump drive situated adjacent the first end faces and being operatively connected to the impellers. A dish-shaped component is situated adjacent at least one of the end faces of at least one of the impellers. The dish-shaped component has an inner wall defining a dish-shaped cavity accommodating an impeller bearing which is in a supporting contact with the inner wall of the component. A stationarily held stub shaft is in alignment with the impeller bearing and projects into the cavity and the impeller bearing received therein for supporting the impeller bearing.

摘要： A method for evacuating a chamber employs a pump arrangement composed of a booster pump and of a downstream forepump is connected to the chamber. The booster pump is accelerated, gas from the chamber is introduced into the booster pump, such that from the booster pump there is temporarily extracted an excess power which exceeds the power provided by the drive of the booster pump. The gas is discharged through a bypass valve while the outlet pressure of the booster pump lies above a predefined threshold value, and the gas is directed to the forepump when the outlet pressure of the booster pump has fallen below the threshold value. The gas supplied by the booster pump is compressed by means of the forepump.

摘要： There is provided a stator that can ensure safe rotation even if a width of a gap between a screw rotor and a stator is particularly smaller than that of a conventional one and can greatly increase a pumping performance of a pump. A stator of the present invention is formed of a metal and a PFA film is provided on an inner wall surface of a top end surface of a screw rotor. After coating the inner wall surface with PFA, followed by melting and remelting processes, the PFA film is formed to have a high smoothness. The stator is placed with a gap between the inner wall surface and the top end surface. If the PFA film of the present invention is provided in a predetermined manner, the width of the gap can be made significantly smaller than that of a conventional one.

摘要： A compressor flange for connecting a screw-type compressor to a drive, wherein the compressor flange has a central opening for receiving a shaft and/or a bearing and a first annular bearing face for bearing on a housing of the compressor and a second annular bearing face for bearing on a housing of the drive. The compressor flange also has axially and/or radially effective seals for forming a seal with respect to the compressor housing and/or the shaft, with the result that an open compressor housing can be closed off and sealed by insertion of the compressor flange. The device relates to a screw-type compressor with such a compressor flange.
