PROCEDURE AND SYSTEM FOR INSPECTION OF WORKING BLADES OF TURBINE AND CASE OF TURBINE Russian patent published in 2011 - IPC F01D25/00

Abstract RU 2415273 C2

FIELD: machine building.

SUBSTANCE: procedure for inspection of working blades of turbine consists in introduction of optical probe into flow channel of turbine. According to the invention transparent medium is supplied to the flow channel of the turbine during inspection, for example, overheated steam, air or gas creating a transparent local flow in the zone of inspection. Also, according to the invention the system of inspection of working blades of the turbine is equipped with the device for inspection of the working blades installed in the flow channel of the turbine and with the device for supply of transparent medium into the flow channel of the turbine. The case is equipped with a channel for the device supplying transparent medium to the flow channel of the turbine.

EFFECT: procedure and system for inspection of working blades of turbine and case of turbine facilitating scheduled inspection under any load and any parametres of working medium at any stage of operation; facilitation to evaluate turbine service life by its actual condition.
