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 pre-mounted exchange insert of a drill wash device is disclosed for connecting a stationary washpipe to a rotating washpipe, which includes a mechanical seal assembly with a stationary seal ring and a rotating seal ring, a first seal ring carrier on which the stationary seal ring is arranged, a second seal ring carrier on which the rotating seal ring is arranged, a connection component which is configured to connect the exchange insert to the stationary washpipe, and an adjusting mechanism operative in an axial direction with a screw connection for changing an axial length of the exchange insert, wherein the screw connection is connected to the second seal ring carrier to permit, in an axial direction, an adjustment of the second seal ring carrier, the mechanical seal assembly, and the first seal ring carrier relative to the connection component.

Pre-mounted exchange insert of a drill wash device

The invention relates to a mechanical seal arrangement comprising a rotating slide ring () and a stationary slide ring () which define a sealing gap () between them and a bandage () which is arranged on the outer surface of at least one of the slide rings, the slide ring () on which the bandage () is arranged comprising a step (), which extends completely on the outer circumferential face in the circumferential direction and has a contact face (), and an end face () of the bandage () lying against the contact face () of the step ().

Mechanical seal having a precisely positioned bandage

A seal ring for a mechanical seal, comprising a base body, a first layer applied to a first face side of a base body, and a second layer applied to a second face side of the base body. At least one of the layers is configured as a slide surface of the seal ring.

Seal ring of a mechanical seal assembly having properties extending the running time, and method for the production thereof

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.
