Abstract

EN UN PROCEDIMIENTO PARA RECUBRIMIENTO DE ALABES DE UNA MAQUINA TERMICA ROTATIVA, SE SOMETE A UN PRIMER PROCESO DE LIMPIEZA EN CONDICIONES DE FUNCIONAMIENTO DE LA MAQUINA, ES DECIR "ON LINE" DONDE EL CORRESPONDIENTE MEDIO DE LIMPIEZA SE DIRIGE A LOS ALABES SIN CUBRIR O CUBIERTOS EN LA CORRIENTE DE AIRE DEL COMPRESOR. DESPUES DE PARAR LA MAQUINA Y ABRIRLA SE SOMETEN LOS ALABES EN CONDICIONES ESTACIONARIAS TANTO DEL ROTOR CORRESPONDIENTEMENTE ALABEADO O DEL ESTATOR A UN PROCESO DE PREPARACION PARA LA SIGUIENTE ETAPA DE TRATAMIENTO. ESTE PROCESO DE PREPARACION PUEDE HACERSE SEGUN DEMANDA O NECESIDAD, LOS ALABES SON SUMERGIDOS EN UN BAÑO EROSIVO VIBRATORIO U OSCILANTE. EL RECUBRIMIENTO PROPIAMENTE DICHO DE LOS ALABES SE CONSIGUE POR MEDIO DE UN PROCESO DE APORTACION CON LLAMA DE ALTA VELOCIDAD, EN EL QUE LA CAPA DE PROTECCION ES APORTADA CON UNA VELOCIDAD DE PARTICULAS DE AL MENOS 300 M/S SOBRE LA SUPERFICIE DEL MATERIAL BASE. A CONTINUACION LOS ALABES SON SOMETIDOS A UN TRATAMIENTO POSTERIOR,QUE SEGUN NECESIDAD EN FUNCION DE LA DISMINUCION DE LA ASPEREZA SUPERFICIAL SIRVE PARA LA APLICACION DE OTRA CAPA PREVISTA.IN A PROCEDURE FOR THE COVERING OF WINGS OF A ROTARY THERMAL MACHINE, A FIRST CLEANING PROCESS IS CONDUCTED IN CONDITIONS OF OPERATION OF THE MACHINE, WHICH IS SAYING "ON LINE" WHERE THE CORRESPONDING MEANS OF CLEANING GOES TO THE CLOUDS WITHOUT CUBE IN THE COMPRESSOR AIR CURRENT. AFTER STOPPING THE MACHINE AND OPENING IT, THE ALBS ARE SUBMITTED IN STATIONARY CONDITIONS, BOTH OF THE CORRESPONDING ROTOR OR THE STATOR, TO A PREPARATION PROCESS FOR THE NEXT TREATMENT STAGE. THIS PREPARATION PROCESS CAN BE DONE AS REQUIRED OR NEEDED, THE WINGS ARE DIPPED IN A VIBRATORY OR OSCILLATING EROSIVE BATH. PROPERLY SAID COATING OF THE WINGS IS ACHIEVED THROUGH A HIGH SPEED CONTRIBUTION PROCESS, IN WHICH THE PROTECTIVE LAYER IS CONTRIBUTED WITH A SPEED OF PARTICLES OF AT LEAST 300 M / S OVER THE SURFACE OF THE BASE MATERIAL. BELOW THE WINGS ARE SUBJECTED TO A FURTHER TREATMENT, WHICH, ACCORDING TO THE NECESSITY DEPENDING ON THE DECREASE OF THE SURFACE RUGGING, IS SUITABLE FOR THE APPLICATION OF ANOTHER LAYER INTENDED.
