Abstract
UN ANILLO DE FORRO PARA UNA BOMBA PROVISTA ENTRE LA CARCASA DE LA BOMBA Y EL IMPULSOR PARA COMPROBAR EL CONTRAFLUJO. EL ANILLO DE FORRO COMPRENDE UN ALOJAMIENTO PROVISTO EN EL CUERPO DE LA CARCASA, UN MIEMBRO DESLIZANTE PROVISTO EN EL ALOJAMIENTO DE FORMA QUE SE PROPORCIONA UNA CIERTA ABERTURA EN DIRECCION RADIAL ENTRE EL MIEMBRO DESLIZANTE Y EL IMPULSOR, Y DE UN MIEMBRO ELASTICO PROVISTO ENTRE EL MIEMBRO DESLIZANTE Y EL ALOJAMIENTO. DE ACUERDO CON LA INVENCION ACTUAL, SE ALOJA EL MIEMBRO DESLIZANTE EN EL ALOJAMIENTO HECHO DE LAMINAS METALICAS DE FORMA QUE SE PROPORCIONE UNA CIERTA ABERTURA ENTRE EL MIEMBRO DESLIZANTE Y EL ALOJAMIENTO. LA ABERTURA CORRESPONDE A LA VARIACION DE DIMENSION PRODUCIDA POR LA DIFERENCIA DEL COEFICIENTE DE EXPANSION TERMICA ENTRE EL MIEMBRO DESLIZANTE Y EL ALOJAMIENTO. LA ABERTURA ESTA SELLADA POR EL MIEMBRO ELASTICO PROPORCIONADO ENTRE EL MIEMBRO DESLIZANTE Y EL ALOJAMIENTO.
