Abstract
The invention relates to a gas-lubricated mechanical seal arrangement using a gaseous fluid as a barrier medium, comprising a mechanical seal comprising a rotating slide ring () and a stationary slide ring () defining a seal gap () therebetween, a biasing means () biasing the stationary slide ring () towards the rotating slide ring (), a fluid space (), into which the gaseous fluid can be introduced, a first slide ring carrier () for retaining the rotating slide ring (), the first slide ring carrier () having a first axial surface (), a second slide ring carrier () for retaining the stationary slide ring (), the second slide ring carrier () having a second axial surface (), the second slide ring () and the stationary slide ring () being arranged together on a displacement surface () so as to be displaceable in the axial direction (X-X), an axial gap (), which is limited by the first axial surface () and the second axial surface (), and an antechamber () which is formed at the sealing gap () of the mechanical seal and which is connected to the fluid space () via the axial gap ().
