| Abstract: | This paper presents some fault diagnosis models for steam turbine blading components. The paper describes the characteristic signa1s, symptoms and rules for diagnosing the following 10 kinds of failures: downdrop of fractured control valve steams, nozzle abrasion,diaphragms plugged by fractured blades, blade fouling, blading erosion by solid particles, water induction, rotor deformation, axial rubbing between rotating and stationary parts,steam whirl of turbine and vacuum deteri oration. Diagnosis medels based on the theory of reliability are given together with formulas for calculating the failure proba bility of the above mentioned 10 kinds of failures as well as some practical examples. |
