Abstract

Dispositivo fabricado a base de un material compuesto para controlar la anchura de la hendidura entre el rotor y la carcasa de una turbomáquina, que transporta un fluido en forma de líquido y/o vapor, en particular una bomba centrífuga, en la que un primer componente material (2) del material compuesto se ha diseñado como un componente de estabilización de la forma y se caracteriza por que un segundo componente material del material compuesto se ha configurado como un material de hinchamiento, de manera que éste provoca un cambio de volumen por la acción de la humedad y donde al menos una cara de la pared del dispositivo que limita con la hendidura puede verse alterada espacialmente debido al material de hinchamiento (5).Device made of a composite material to control the width of the groove between the rotor and the housing of a turbomachine, which carries a fluid in the form of a liquid and / or steam, in particular a centrifugal pump, in which a first component material (2) of the composite material has been designed as a component of stabilization of the form and is characterized in that a second material component of the composite material has been configured as a swelling material, so that this causes a change in volume by the moisture action and where at least one face of the wall of the device that borders the groove can be spatially altered due to the swelling material (5).
