Bomba centrífuga de flujo mixto para piscinas.Mixed flow centrifugal pump for swimming pools.
La presente invención, según se expresa en el enunciado de esta memoria descriptiva se refiere a una bomba centrífuga de flujo mixto para piscinas, cuyo cuerpo hidráulico y prefiltro están materializados totalmente en plástico, con las consiguientes ventajas de un menor peso y un menor coste de fabricación respecto de los convencionales.The present invention, as expressed in the statement of this specification refers to a bomb mixed flow centrifuge for swimming pools, whose hydraulic body and prefilter are materialized entirely in plastic, with the consequent advantages of a lower weight and a lower cost of manufacturing compared to conventional ones.
Las bombas centrífugas de flujo mixto que se utilizan en piscinas, están fabricadas en metal generalmente en acero y bronce, y presentan un cuerpo principal hidráulico en forma de voluta de Arquímedes y un cuerpo auxiliar o de prefiltro, con las consiguientes bridas de acoplamiento a motor y a las entrada y salida correspondientes.The mixed flow centrifugal pumps that are used in swimming pools, they are usually made of metal in steel and bronze, and have a hydraulic shaped main body of Archimedes' volute and an auxiliary or prefilter body, with the consequent motor coupling flanges and the inlets and corresponding output.
De forma genérica, dichas bombas se materializan en fundición gris GG25 y en menor medida en bronce marino RG5 especialmente recomendada para agua de mar.In a generic way, these pumps materialize in gray cast iron GG25 and to a lesser extent in marine bronze RG5 Especially recommended for seawater.
En estas bombas, sobre todo las de fundición gris, siempre ha habido un problema con el óxido, sobre todo cuando la bomba está parada un tiempo y se quiere volver a ponerla en funcionamiento, en cuyo caso la primera salida de fluido es generalmente con óxido.In these pumps, especially foundry ones gray, there has always been a problem with rust, especially when the pump is stopped for a while and you want to put it back on in operation, in which case the first fluid outlet is usually with rust.
Por otro lado las bombas metálicas resultan con un elevado peso, lo que dificulta su manejo, sobre todo a la hora de ensamblaje, empaquetamiento y transporte.On the other hand metal pumps result with a high weight, which makes handling difficult, especially at the time of assembly, packaging and transport.
También es de destacar que las bombas metálicas, sobre todo las de bronce, presentan el inconveniente de la aparición frecuente de micro-poros, con los consiguientes problemas que esto conlleva.It is also noteworthy that metal pumps, especially those of bronze, have the disadvantage of frequent appearance of micro-pores, with consequent problems that this entails.
Igualmente, es de destacar otro inconveniente de las bombas metálicas, consistente en que no cumplen con las especificaciones de seguridad establecidas en cuanto al aislamiento de la parte hidráulica y de la parte eléctrica.Likewise, another drawback of the metallic pumps, consisting of not complying with the safety specifications established for insulation of the hydraulic part and the electrical part.
Finalmente, como otro antecedente importante de las bombas metálicas, es la aparición del fenómeno llamado "electrólisis", ya que al ser la turbina de bronce y la bomba de fundición gris, provoca su aparición y consiguiente desgaste de materiales.Finally, as another important antecedent of the metallic bombs, is the appearance of the phenomenon called "electrolysis", since being the bronze turbine and the pump gray cast iron, causes its appearance and consequent wear of materials.
La bomba objeto de la invención, presentando las mismas dimensiones que las comentadas bombas metálicas convencionales en hierro y bronce, se caracteriza porque está materializada en plástico (preferentemente polipropileno) de manera que el cuerpo hidráulico en voluta está constituido entre dos partes independientes obtenidas en un proceso de moldeo por inyección y unidas perimetralmente entre si mediante tornillos, con la interposición de una junta de estanqueidad. Cada parte de dicho cuerpo hidráulico se obtendrá en un molde diferente, es decir, un molde con la forma conveniente para cada una de las dos partes, en las que se establecerá además el cuerpo de prefiltro de la propia bomba. Es decir, en el cuerpo hidráulico de material plástico de la bomba está conformada la voluta de Arquímedes completa.The pump object of the invention, presenting the same dimensions as the mentioned metal pumps conventional in iron and bronze, it is characterized because it is materialized in plastic (preferably polypropylene) so that the volute hydraulic body is constituted between two independent parts obtained in a molding process by injection and perimetrically joined together by screws, with the interposition of a seal. Every part of said hydraulic body will be obtained in a different mold, that is, a mold with the appropriate shape for each of the two parts, in which will also establish the pre-filter body itself bomb. That is, in the hydraulic body of plastic material of the Pump is made up of the complete Archimedes scroll.
En una de las partes que constituye la bomba, está conformada igualmente la brida de anclaje del motor, existiendo una segunda brida de anclaje en la boca de impulsión para cierre de la voluta.In one of the parts that constitutes the pump, the motor anchor flange is also formed, there is a second anchor flange in the discharge mouth to close the scroll.
De la constitución y características de la bomba referida se deducen una serie de ventajas frente las bombas convencionales, pudiendo citar como más importantes las siguientes:The constitution and characteristics of the pump referred to a series of advantages are deduced against pumps conventional, citing as more important the following:
- --
- Menor coste de fabricación.Minor manufacturing cost
- --
- Mismas prestaciones que las bombas de hierro y de bronce.Same performance than iron and bronze pumps.
