ABSTRACT:
The invention relates to an apparatus for evaluating the slippage of a mechanical seal comprising: a high frequency vibration sensor, attached to the outside of the mechanical seal of a rotary machine equipped with the mechanical seal, for measuring the high frequency vibration which is generated by the mechanical seal in the operating mode; and a microcomputer for receiving the output of the high frequency vibration sensor, for analyzing the high frequency vibration which is generated by the mechanical seal in each state of the slippage surfaces of the mechanical seal, and for outputting the evaluation value of the slippage of the mechanical seal.
