Abstract
A method for determining wear volume of a mechanical seal includes measuring a temperature at a seal face or seat of the mechanical seal with high temporal resolution. An area under a function of a measured temperature profile in a case of short-term temperature changes which are less than 60 s, compared with a normal temperature, which corresponds to a temperature profile of a mechanical seal without wear, is determined by measuring the temperature profile with subsequent integration of a function of the measured temperature profile. The area being multiplied by a mechanical seal-specific factor in order to calculate the wear volume.

A method for determining wear volume of a mechanical seal in case of singular wear events, the method comprising:
- measuring a temperature (Tv) at a seal face or seat of the mechanical seal with high temporal resolution, wherein
- an area (Av) under a function of a measured temperature profile (Tv=f(t)) in a case of short-term temperature changes (dt) which are less than 60 s, compared with a normal temperature (TN), which corresponds to a temperature profile of a mechanical seal without wear, is determined by measuring the temperature profile (Tv) with subsequent integration of a function of the measured temperature profile (Tv=f(t)), the area (AV) being multiplied by a mechanical seal-specific factor in order to calculate the wear volume.
