Sistema de información para la caracterización de imágenes de desgaste en álabes de rotor de una turbina de gas

Abstract

In Mexico, the end user of gas turbines (PEMEX), in the NRF standard, requests the Goodman and Campbell diagrams for the acquisition of new turbo machinery. However, the requirement of the diagrams is not reported when the turbine is sent for overhaul. In this research article, it is suggested that the end user when carrying out a wear analysis of a turbine blade, know precisely the conditions of a blade in case of total loss of the machine or in conditions in which they send one or several turbine discs to the manufacturer and the conditions that receives after overhaul the discs. Wear and friction are the most adverse factors in reducing the useful life of mechanical equipment. The loss of a relatively small amount of material, in certain critical locations of any mechanical part, can make the difference between the damage and the good functioning of the gas turbine, so this research aims to characterize images of a turbine blade with in order to identify any wear or mechanical failure; analyzing the responses to deterministic and non-deterministic variables, looking for responses that contribute to the early detection of any mechanical failure that prevents the total loss of the gas turbine in operation. To achieve the objectives set out in this research, techniques and tools with a systemic and systematic approach are used, which will allow the characterization and interpretation of images of gas turbine blades.
