Water treatment system for ultrasonic inspection of turbine rotors from the bore

摘要

A system for deaerating water utilized to flood a bore of a turbine rotor which is to be ultrasonically inspected in which the bore is inclined and evacuated and heated water enters the bore and impinges on a surface that breaks up the influent stream of water to substantially increase its surface area to assist in the deaeration, the bore being connected to a trough partially filled with heated water to a level above the bore to maintain the flooded condition of the bore during the ultrasonic inspection.
