Abstract

DONDE DICHA MAQUINA ES ATRAVESADA POR UN FLUJO PRINCIPAL DE AGUA Y TIENE UN ORGANO CUYA SUPERFICIE ESTA MOJADA POR EL FLUJO PRINCIPAL, Y EXISTEN MEDIOS DE INYECCION, AL NIVEL DE LA SUPERFICIE MOJADA, DE UN FLUJO DE SECUNDARIO DE AGUA DONDE LOS MEDIOS DE INYECCION TIENEN MEDIOS PARA DISMINUIR LA CANTIDAD DE PARTICULAS ABRASIVAS DE UNA PORCION DE UN FLUJO DE AGUA QUE CONSTITUYE LA FUENTE DE FLUJO PRINCIPAL; Y MEDIOS DE TRANSPORTE, A PARTIR DE MEDIOS DE DISMINUCION Y HACIA LA SUPERFICIE MOJADA, DONDE EL FLUJO SECUNDARIO QUE TIENE UNA CANTIDAD DE PARTICULAS ABRASIVAS MENOR QUE AQUELLA DEL FLUJO PRINCIPAL, DONDE LOS MEDIOS PARA DISMINUIR LA CANTIDAD DE PARTICULAS ABRASIVAS DE UNA PORCION DE FLUJO DE ENTRADA DE LA MAQUINA PERMITEN TENER UNA CANTIDAD DE AGUA "CLARA" O RELATIVAMENTE PROPIA QUE SE PUEDE USAR EN EL CENTRO DE LA MAQUINA PARA INYECTAR AL NIVEL DE LA SUPERFICIE MOJADA. ADEMAS, SE DESCRIBE UN PROCESO DE PREVENCION DE DESGASTE DE LA MAQUINA HIDRAULICA, QUE CONSISTE EN: a) DISMINUIR LA CANTIDAD DE PARTICULAS ABRASIVAS DE UNA PORCION DE UN FLUJO DE AGUA, Y b) INYECTAR, AL NIVEL DE LA SUPERFICIE MOJADA, UN FLUJO SECUNDARIA DE AGUA PROVENIENTE DE LA PORCION DEL FLUJO DE AGUA CUYA CANTIDAD DE PARTICULAS ABRASIVAS HA DISMINUIDO
