Abstract:By virtue of a thorough analysis for frequent failure of electro-hydraulic servo valve occurred in Xinhai Power Generation Co. ,Ltd. ,the structure theory,failure form and source of electro-hydraulic servo valve are discussed, emphasizing the influence acid number and granules of flame resistant oil. Much successful experience of other power plants is used in the process of analysis. Measures have been taken from overhauling and operation, and thus this hidden trouble is solved ,which imperiled the security of turbine-generator unit, prolonged the life of electro-hydraulic servo valve and economized the cost of running.
Keywords:steam turbine  electric hydraulic control system(DEH)  servo valve  invalidation analysis  countermeasure
