Abstract

EN UN EQUIPO PARA AMORTIGUACION DE VIBRACIONES DE PALETAS EN UNA TURBOMAQUINA RECORRIDA CON CORRIENTE AXIAL, SE COMPRIMEN LOS EXTREMOS (8) DE LAS PALETAS (2) GIRATORIAS CONTRA LA PARED LIMITADORA DE CORRIENTE DE UNA CARCASA (1) DE TURBINA. SOBRE ESTA PARED LIMITADORA DE CORRIENTE DE LA CARCASA DE TURBINA SE APLICA EN DIRECCION RADIAL CONTRA EL EXTREMO (8) DE LA PALETA UN ANILLO (4) A BASE DE MATERIAL MAGNETICO PERMANENTE, QUE SE COMPONE AL MEMOS DE UNO O MULTIPLES ANILLOS (6) PARCIALES DE IGUAL O DIFERENTE POLARIZACION MAGNETICA. LOS EXTREMOS (8) DE LAS PALETAS ESTAN PROVISTOS CON UNA PLACA (3) DE CUBIERTA, QUE SE COMPONE DE MATERIAL CONDUCTOR ELECTRICO.
