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

The invention relates to a mechanical seal arrangement comprising a mechanical seal () having a rotating seal ring () and a stationary seal ring () defining a seal gap () therebetween, a secondary seal () arranged on a back surface of one of the seal rings facing away from a sealing surface of the seal ring, the secondary seal () being made of a base material and having a coating () such that a material bond is formed between the coating () and the base material of the secondary seal, the secondary seal () being made of a base material and having a coating () such that a substance-to-substance connection is formed between the coating () and the base material of the secondary seal, a sleeve-shaped member () arranged radially inside the secondary seal (), wherein a gap () having a gap height (H) is present between the sleeve-shaped component () and a region of one of the sliding rings facing radially inwards, the secondary seal () seals against the back side of this slide ring and the sleeve-shaped component (), wherein the coating () is provided on a first side () of the secondary seal (), which first side facing the sliding ring, and a second side () of the secondary seal () which second side facing the sleeve-shaped component (), wherein a stiffness of the coating () is greater than a stiffness of the base material of the secondary seal () and wherein a thickness (D) of the coating is smaller than or equal to a gap height (H) of the gap ().

Mechanical seal arrangement having an improved secondary seal

The invention relates to a mechanical seal assembly comprising a mechanical seal with a rotating slide ring and a stationary slide ring, wherein one of the two slide rings has a first slide surface, wherein the other of the two slide rings has a second slide surface with a circumferentially closed sealing blade which protrudes from a bottom region of the second slide surface in the direction of the first slide surface by a height (H), wherein the sealing blade has a width (B) in a range of between 10 and 500 &#x3bc;m, wherein at least one pre-tensioning element braces the slide rings against each other, wherein the second slide surface and the sealing blade on the second slide surface have a diamond coating.

Mechanical seal arrangement with minimal leakage

The invention relates to a mechanical seal arrangement comprising: a rotating slide ring () having a first slide surface and a stationary slide ring () with a second slide surface which between them define a sealing gap, wherein the first and second slide surfaces have different hardnesses, wherein the harder slide surface has a diamond coating () and the softer slide surface is produced from carbon composite material, and wherein an average initial roughness R(of the diamond coating) is less than an average initial roughness Rof the slide surface made from carbon composite material.

Mechanical seal arrangement having sliding surfaces of different hardness

The invention relates to a bearing component, comprising a base body () and an opening () which is formed in the base body () and on which an internal bearing face is formed, the internal bearing face having a diamond coating (), and the diamond coating () having elongate depressions () extending substantially in the longitudinal direction (X-X) of the opening.

Bearing component comprising an inner diamond coating

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

The present invention refers to a seal ring for a mechanical seal, comprising: a base body () with a diamond layer () which is applied to the base body () and configured as a sliding surface, wherein the diamond layer () has a thickness (D) which is less than or equal to 4 &#x3bc;m, particularly less than or equal to 3 &#x3bc;m, particularly less than or equal to 2 &#x3bc;m, particularly preferably about 1 &#x3bc;m, and wherein the base body () is without fissures or only comprises fissures that have a maximum longitudinal extension (L) on a surface of the base body () or in the base body () that is less than or equal to 5 &#x3bc;m.

Low-friction seal ring with inexpensive diamond coating

This invention refers to a waste disposal plant for wet garbage, especially for refuse from large-scale kitchens. The wet garbage is transported by compressed air or a partial vacuum from decentralized input stations () to a central discharge device (). A sieve-like collecting funnel () is provided there, from which liquid exits to an external collection area () and is drained off at intervals. The remaining wet garbage has thus already been largely drained when is passed on for further processing, for instance to a grinder () and a water extraction press (), before being fed for instance to a food refuse silo ().
