Title: TIGHTNESS TEST EVALUATION MODULE FOR A VALVE AND ACTUATOR MONITORING SYSTEM
Abstract:
The present application provides a method of evaluating valve (270,280) tightness in a turbine (100) by a data acquisition system. The method may include the steps of receiving a number of operating parameters from a number of sensors (380), wherein the operating parameters may include rotor acceleration and rotor speed, comparing the rotor acceleration and the rotor speed to predetermined values, and altering one or more of the operating parameters and/or initiating repair procedures if the rotor acceleration and/or the rotor speed is increasing and/or exceeds predetermined values.
