Abstract

UNA BOMBA GEROTOR QUE TIENE UN MONTAJE DE CUERPO EJE-ROTOR CON UNA LONGITUD AXIAL REDUCIDA QUE COMPRENDE UN ROTOR DE LOBULO MACHO ENTRELAZADO INTERNAMENTE A UNA CORONA CIRCULAR DE LOBULOS HEMBRA, TENIENDO DICHA CORONA CIRCULAR POR LO MENOS UN LOBULO MAS QUE EL ROTOR, SIENDO LOS EJES DE SIMETRIA DEL ROTOR Y DE LA CORONA EXCENTRICOS PARA CREAR UNA SERIE DE CAMARAS ENTRE LOS LOBULOS, Y DICHAS CAMARAS SE DESPLAZAN ALREDEDOR DE LOS EJES DE SIMETRIA DURANTE LA ROTACION DE LAS PARTES DE LA BOMBA, AUMENTADO DE TAMANO AL PASAR POR UNA ENTRADA Y DISMINUYENDO AL PASAR POR UNA SALIDA, ESTANDO FORMADAS DICHA ENTRADA Y SALIDA POR MEDIO DE UN CUERPO DE BOMBA EN EL CUAL LA CORONA ESTA MONTADA ROTATORIAMENTE, TENIENDO UN EJE FIJO AL CUERPO DE BOMBA SOBRE EL CUAL EL ROTOR DE LOBULO MACHO Y UN ENGRANAJE CONDUCTOR ESTAN MONTADOS ROTATORIAMENTE A DICHO ROTOR, ESTANDO DICHO ROTOR Y DICHO ENGRANAJE VINCULADOS UNA AL OTRO.A GEROTOR PUMP HAS A ROTOR AXIAL BODY ASSEMBLY WITH A REDUCED AXIAL LENGTH INCLUDING AN INTERNALLY INTERLOCKING MALE LOBE ROTOR WITH A FEMALE CIRCULAR CROWN, THEREFORE HAVING SUCH A CIRCULAR CROWN, THEY ARE LEAST ONE EXCENTRIC ROTOR AND CROWN SYMMETRIA AXLES TO CREATE A SERIES OF CHAMBERS BETWEEN THE LOBES, AND SUCH CHAMBERS MOVE AROUND THE SYMMETRIA AXLES DURING THE ROTATION OF THE PARTS OF THE PUMP, INCREASED BY SIZE AND PASSING DECREASING AS IT GOES THROUGH AN EXIT, SUCH INPUT AND OUTPUT ARE FORMED THROUGH A PUMP BODY IN WHICH THE CROWN IS ROTALLY MOUNTED, HAVING A FIXED SHAFT TO THE PUMP BODY ON WHICH THE MALE LOBE ROTOR AND A GEAR. ROTATELY MOUNTED TO SUCH ROTOR, SUCH ROTOR AND SUCH GEAR ARE LINKED TO EACH OTHER.
