The invention relates to a method of operating a mechanical seal assembly () having a mechanical seal () with a rotating sliding ring () and a stationary sliding ring (), defining a sealing gap () between the sliding surfaces thereof, comprising the steps of: collecting operating data and/or environmental data of the mechanical seal (), transmitting the collected operating data and/or environmental data to a digital twin () of the mechanical seal (), simulating and monitoring the operation of the mechanical seal () using the digital twin () based on the transmitted operating data and/or environmental data of the mechanical seal (), and retransmitting a simulation result and/or data of the digital twin.

Method for operating a mechanical face seal assembly, and mechanical face seal assembly

A mechanical face seal includes a rotating counter ring having a sealing surface and two radial planes. Each of the radial planes is associated with a clamping cam. A stationary face seal ring has a sealing surface opposite from the sealing surface of the counter ring. The sealing surfaces of the counter ring and the face seal ring bear against each other.

Mechanical face seal with a rotating counter ring and precisely defined clamping

A mechanical face seal includes a rotating counter ring having a sealing surface and a stationary face seal ring having a sealing surface. The sealing surface of the counter ring is disposed opposite from the sealing surface of the face seal ring. The sealing surfaces of the counter ring and the face seal ring bear against each other.

Mechanical face seal

A slide ring seal arrangement comprises a rotationally fixed slide ring () and a slide ring (), which is provided for rotating together with a rotating component, these slide rings each being held in a loose seat and interacting, in, in essence, radially oriented sealing surfaces, which are prestressed with a main prestressing force while in contact with one another. Each slide ring, on its front face that faces away from the sealing surface, is axially supported on a supporting part () via an annular bearing surface () provided between the respective supporting part and the adjacent front face of the respective slide ring. A load ratio (d&#x2212;d)/(d&#x2212;d) of =2.0, preferably between 0.8 and 2.0, preferably no greater than between 1.0 and 1.5, more preferably approximately 1.3 is maintained on the bearing surface (). The measurement (d&#x2212;d) of each bearing surface () is equal to =10 mm, preferably between 0.2 and 2.0, preferably no more than approximately 0.6 mm.

Slide ring seal arrangement

The present invention refers to an apparatus for rotationally fixing a seal ring () of a mechanical seal assembly retained at a mounting component () to be axially movable, comprising a force transmitting ring () retained at the mounting component to be axially movable and a rotation prevention device comprising at least one first engaging member () configured to engage with the mounting component and the force transmitting ring in a form-fit manner and at least one second engaging member () configured to engage with the force transmitting ring and the seal ring in a form-fit manner, the first engaging member being arranged circumferentially offset with respect to the second engaging member, characterized in that the engaging members () protrude axially from the force transmitting ring () or the seal ring () toward the respectively other component (seal ring or force transmitting ring) and are configured to be received in axial recesses () provided in the respectively other component with a play.

Apparatus for rotationally fixing a seal ring of a mechanical seal assembly axially movably retained at a mounting component

A mechanical seal assembly including at least one pair of co-operating seal rings, one of which is provided for common rotation with a rotating component and the other of which is provided rotationally fixed at a stationary component. One of the seal rings is axially movable and axially biased with a biasing force against the other seal ring, the biasing force being transmittable through a force transmitting ring to the respective seal ring, in order to bias facing sliding surfaces of the seal rings, between which a sealing gap is formed during operation, in a mutual sealing engagement, and a secondary sealing assembly provided at the force transmitting ring for sealing the axially movable seal ring with respect to at least one circumferential guiding surface of a guiding component guiding the movement of the seal ring and the force transmitting ring.
