Apparatus for evaluating the slippage of a mechanical seal
First Claim
1. An apparatus for evaluating the sliding state or state of a mechanical seal comprising:
- a high frequency vibration sensor, attached on the casing of a rotary machine equipped with the mechanical seal, for measuring a high frequency vibration such as the acoustic emission which is generated by the mechanical seal in the operating mode; and
a computer for receiving the output of said sensor, for analyzing the high frequency vibration which is generated by the mechanical seal in each state of the sliding surfaces of the mechanical seal, and for outputting evaluation values of the state of the mechanical seal.
