Abstract

COMPRENDE CUATRO CILINDROS DE TRABAJO (1 A 4) COLOCADOS EN FORMA DE ESTRELLA, CON BOMBAS DE EMBOLO (5 A 8) QUE SE COLOCAN COMO BOMBAS INDIVIDUALES EN TORNO A LA MAQUINA DE FORJAR, CON LO QUE TODOS LOS CIERRES DE TUBERIAS (13 A 16) DE LOS LADOS DE LAS BOMBAS ESTAN EN LA SUPERFICIE MEDIA HORIZONTAL DE LA MAQUINA DE FORJAR. CON ELLO PUEDEN REALIZARSE TAN LARGAS O CORTAS COMO SEA POSIBLE TODAS LAS TUBERIAS QUE LLEVAN HACIA LOS CILINDROS DE TRABAJO (9 A 12) PARA COMPARAR Y REDUCIR LAS ELEVADAS PERDIDAS EN LOS CUATRO CILINDROS DE TRABAJO QUE SE DESARROLLAN POR LA COMPRESIBILIDAD DEL MEDIO DE PRESION.
