Abstract
Las abrazaderas de junta de dilatación están instaladas contra orejetas guía de difusores en juntas de dilatación de bomba de chorro. Las abrazaderas pueden prevenir la vibración y/o movimiento en la junta de dilatación mientras que no está sujeta rígidamente al difusor. Las abrazaderas incluyen una aleta de compresión que presiona contra una orejeta guía del difusor en una dirección sustancialmente radial, un miembro de presión entre el miembro de compresión y la orejeta guía que presiona el brazo contra la orejeta guía, y estructuras de soporte que sostienen el brazo y el miembro de presión al mezclador de entrada alrededor de la orejeta guía. Sistemas de abrazaderas de junta de dilatación están instaladas contra varias orejetas guía de un solo difusor. Cada abrazadera puede estabilizar el difusor y el mezclador de entrada permitiendo al mismo tiempo el movimiento relativo ascendente del mezclador de entrada. La colocación y el tensado de las abrazaderas en dicho sistema pueden ser variados para prevenir o reducir las vibraciones y/o oscilaciones entre un mezclador de entrada y un difusor.
