Abstract

EL CABEZAL DE REGISTRO DE CHORRO LIQUIDO (701, 101) COMPRENDE UNA GRAN VARIEDAD DE PUERTAS DE DESCARGA DE LIQUIDO DISPUESTAS (704, 111) PARA DESCARGAR EL LIQUIDO DE REGISTRO, DE UNA GRAN VARIEDAD DE PASAJES DE LIQUIDO (110) CADA UNO COMUNICA CON UNA PUERTA DE DESCARGA Y UNOS MEDIS DE GENERACION DE ENERGIA TERMICA (103) PROVISTOS EN EL PASAJE DE LIQUIDO PARA ACTIVAR LA ENERGIA TERMICA EN EL LIQUIDO DE REGISTRO. LAS PUERTAS DE DESCARGA (704) ESTAN DISPUESTAS DE FORMA QUE LAS AREAS DE APERTURA DE DICHAS PUERTAS ESTAN SITUADAS EN AMBAS PARTES EXTREMAS EN LA DISPOSICION DE LAS PUERTAS DE DESCARGA DE LIQUIDO SON MAS GRANDES QUE LAS DE LAS PUERTAS DE DESCARGA SITUADAS EN LA PARTE CENTRAL. LA GENERACION DE CAMBIO EN LAS GOTAS DE LIQUIDO DESCARGADAS DE LAS PUERTAS DE DESCARGA DE LIQUIDO (704) PODRAN, POR LO TANTO, EVITARSE LO QUE SUCEDE DEBIDO A LA DIFERENCIA DE VISCOSIDAD QUE ES CAUSADA PORQUE LA TEMPERATURA DEL LIQUIDO DE REGISTRO ES MAYOR EN LA PARTE CENTRAL DE LOS PASAJES DE LIQUIDO (110) Y MENOR EN AMBAS PARTES EXTREMAS DE LA MISMA, DEPENDIENDO DE LA RELACION EN LA DISPOSICION DE LOS MEDIOS DE GENERACION DE ENERGIA TERMICA (103), Y PUEDE FORMARSE UNA IMAGEN REGISTRADA NO UNIFORME EN LA DENSIDAD DE REGISTRO .
