Mechanical seal assembly with monitoring function, and method for the same

Abstract

The invention relates to a mechanical seal arrangement comprising a slide ring seal () having a rotating slide ring () and a stationary slide ring () defining a sealing gap () therebetween, the rotating slide ring () having a first slide surface () with a first information structure (), the stationary slide ring () having a second slide surface () with a second information structure () wherein the first information structure () and the second information structure () at least partially overlap in an overlap area (), at least one sensor () for detecting sound and/or vibration, wherein the sound and/or the vibration is generated by the first information structure () when moving past the second information structure (), and an evaluation unit (), which is arranged to compare the sound and/or the vibrations detected with set values and to output a comparison result, characterized in that the second information structure () has a second sliding surface () with a second information structure (), wherein the first information structure () and the second information structure () at least partially overlap in an overlap area ().
