Abstract

LA INVENCION SE REFIERE A UN METODO DE FUNCIONAMIENTO DE UNA BOMBA (1) DE VACIO CON SELLADO DE ACEITE CON UNA TOBERA (8) DE SALIDA PROVISTA CON UNA VALVULA (9) DE RETORNO, UN CONDUCTO (11) DE ALIMENTACION DE ACEITE QUE DISPONE DE UNA VALVULA (13) Y TIENE SU SALIDA EN LA CAMARA DE ASPIRACION DE LA BOMBA, UN MOTOR (14) DE ACCIONAMIENTO ELECTRICO PARA EL ROTOR (4) CON BOBINAS (15 Y 20) Y UN CONDENSADOR (16). LA VALVULA (13) EN EL CONDUCTO (11) DE ALIMENTACION DE ACEITE ESTA CERRADA CUANDO LA BOMBA (11) ESTA CONECTADA EN EL CASO DE CORTE DE POTENCIA. PARA ASEGURAR QUE SE MANTIENE INCLUSO CUANDO SUCEDE UN FALLO MECANICO, SE PROPONE QUE LA VALVULA (13) EN EL CONDUCTO (12) DE ALIMENTACION DE ACEITE DEBA SER CONTROLADA MEDIANTE LA VELOCIDAD ROTACIONAL DEL ROTOR (4) Y DEL MOTOR (14) DE ACCIONAMIENTO, DE FORMA QUE PERMANEZCA ABIERTA EN LA VELOCIDAD DE OPERACION NORMAL Y QUE SE CIERRE CUANDO SE REDUCE LA VELOCIDAD; LA BOBINA (20) AUXILIAR DEL MOTOR PUEDE SERVIR COMO SENSOR.
