摘要： A turbocompressor shaft seal, especially for a high-pressure turbocompressor, has each of its gas-side and atmosphere-side slide rings biased toward a rotor ring of the shaft and associated with blocking-liquid compartments which are interconnected by an annular passage around the rotor ring. The compartments are connected in a closed circulation path with a circulating pump and a cooler and leakage liquid is returned by a feed pump to the liquid circulation with the aid of a pressure transformer biased on one side by the gas pressure to be sealed and an adjustable spring force and, on the other side, by the pressure of the blocking liquid.

摘要： A high pressure sealing arrangement of the type in which a rotor sealing ring end face defines a gas pressure with a stator sealing ring end face has a functional gap between a cylindrical portion of the seal housing and the stator sealing ring bridged by an O-ring of reduced hardness. The polar or geometric moment of inertia of the stator sealing ring is sufficiently large that the gap width of the functional annular gap between the shaft-side cylindrical part of the sealing ring in the operational state and under the operational differential pressure corresponds to the structurally predetermined gap width of the mounting ring gap between the cylindrical part of the sealing housing and the stator sealing ring in all operational states and is less than 0.4 mm and preferably less than 0.3 mm. The sealing O-ring additionally serve as a compensation or centering ring and, for this purpose, has a material hardness which is greater than the extrusion threshold of this material through the gap and for the given gap width at the predetermined operating pressure differential and is less than a hardness of 90 Shore A according to German Industrial Standard DIN 53505 preferably the hardness of the O-ring is less than 80 Shore A under this standard. In other words according to the invention the parts are related and dimensioned that the orientations of the sealing end faces of the rotor sealing ring and the stator sealing ring do not change in operation and preferably are always parallel.

摘要： A high pressure sealing arrangement of the type in which a rotor sealing ring end face generates a gas pressure with a stator sealing ring end face at a functional gap between a cylindrical portion of the seal housing and the stator sealing ring bridged by an O-ring of reduced hardness.

The sealing O-ring additionally serve as a compensation or centering ring and has a material hardness which is greater than the extrusion threshold of this material through the gap and is less than a hardness of 90 Shore A according to German Industrial Standard DIN 53505.
