Verfahren zur Herstellung von in Integralbauweise ausgebildeten Laufrädern für Verdichter und Turbinen

摘要

#CMT# #/CMT# The method involves measuring the natural frequency of each individual blade in connection with the molding. The blade mass of the individual blades is determined from the correlation between the blade natural frequency and the blade mass. The deviation of the blade mass is determined from the blade with the smallest blade mass for each blade. The deviation of the blade mass is eroded by the individual blades from the smallest blade mass with an etching agent, so that all blades have masses and natural frequencies corresponding with the smallest blade mass and natural frequency. #CMT#USE : #/CMT# Method for manufacturing impellers for compressors and turbines, particularly for gas turbine power plants. #CMT#ADVANTAGE : #/CMT# The method involves measuring the natural frequency of each individual blade in connection with the molding and the blade mass of the individual blades is determined from the correlation between the blade natural frequency and the blade mass, where the deviation of the blade mass is determined from the blade with the smallest blade mass for each blade, and thus an increased life span of the impeller is ensured.
