OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo de extracción e inserción de rodetes para bombas verticales multicelulares que permite llevar a cabo la extracción e 10 inserción de los rodetes sin tener que llevar a cabo movimientos en dicha bomba que conllevan el gripado entre el rodete y el eje de giro del mismo.The present invention relates to an impeller extraction and insertion device for multicellular vertical pumps that allows the extraction and insertion of the impeller to be carried out without having to carry out movements in said pump that involve the seizure between the impeller and the axis of rotation of the same.
El objeto de la presente invención es un dispositivo de extracción e inserción de rodetes para bombas verticales multicelulares, preferiblemente las dispuestas en 15 centrales nucleares, que evita los riesgos inherentes a la extracción e inserción de los rodetes en posición horizontal de la bomba y la posibilidad de contaminación tanto de trabajadores como de otras máquinas por parte del material radioactivo con el que está en contacto la bomba vertical multicelular.The object of the present invention is an impeller extraction and insertion device for multicellular vertical pumps, preferably those arranged in 15 nuclear power plants, which avoids the risks inherent in the extraction and insertion of the impeller in a horizontal position of the pump and the possibility of contamination of both workers and other machines by the radioactive material with which the multicellular vertical pump is in contact.
20 ANTECEDENTES DE LA INVENCIÓN20 BACKGROUND OF THE INVENTION
Se conocen en el estado de la técnica los dispositivos de extracción e inserción de rodetes para bombas verticales multicelulares de centrales nucleares que llevan a cabo un desplazamiento de la bomba a una posición distinta a la de operación, lo que 25 conlleva movimientos en dicha bomba que conllevan el gripado entre el rodete y el eje de giro del mismo, ya que ambos suelen estar fabricados en acero inoxidable, donde la única solución es desechar el eje con todos los rodetes dispuestos en el mismo. Esto conlleva unos costes muy elevados, ya que cada rodete puede tener un coste de aproximadamente 1.000.000 €.The devices for extracting and inserting impellers for multicellular vertical pumps of nuclear power plants that carry out a displacement of the pump to a different position from the operation are known in the state of the art, which entails movements in said pump which entail the seizure between the impeller and the axis of rotation of the same, since both are usually made of stainless steel, where the only solution is to discard the axis with all the impellers arranged therein. This entails very high costs, since each runner can have a cost of approximately € 1,000,000.
Este desplazamiento hace que todas las operaciones de mantenimiento de la bomba se deban llevar en posición horizontal, requiriendo unos espacios muy elevados y unos elementos auxiliares, tales como grúas.This displacement means that all the maintenance operations of the pump must be carried out in a horizontal position, requiring very high spaces and auxiliary elements, such as cranes.
Por otra parte, el espacio disponible para desmontar la bomba vertical multicelular en su posición de operación es muy reducido, ya que se debe extraer en los pozos donde se encuentran dispuestas las bombas, lo que dificulta soluciones in situ, Además, el transporte de dichas bombas presenta problemas de contaminación tanto de 5 trabajadores como de otras máquinas por parte del material radioactivo con el que está en contacto la bomba vertical multicelular.On the other hand, the space available to disassemble the multicellular vertical pump in its operating position is very small, since it must be extracted in the wells where the pumps are arranged, which makes it difficult to find solutions in situ, In addition, the transport of said Pumps presents contamination problems of both workers and other machines by the radioactive material with which the multicellular vertical pump is in contact.
El dispositivo de extracción e inserción de rodetes para bombas verticales multicelulares de la presente invención solventa todos los inconvenientes anteriores ya 10 que presenta una configuración que permite llevar a cabo la extracción e inserción de los rodetes de la bomba in situ, sin tener que extraer la misma, y evitando el gripado entre el eje y dichos rodetes.The impeller extraction and insertion device for multicellular vertical pumps of the present invention solves all the above drawbacks and 10 which has a configuration that allows the extraction and insertion of the impeller of the pump in situ, without having to remove the same, and avoiding the seizure between the shaft and said impellers.

ellas transmite a su vez el movimiento a un cadena, donde las al menos dos cadenas son acoplables al rodete en dos puntos diametralmente opuestos.they in turn transmit the movement to a chain, where the at least two chains are attachable to the impeller at two diametrically opposite points.
De esta manera, el tiro efectuado por las cadenas al llevar a cabo la extracción del rodete es vertical, síncrono y equilibrado, de forma que el rodete siempre permanece perpendicular al eje de giro de dicho rodete, y por tanto el agujero del rodete donde va dispuesto el eje es concéntrico a dicho eje durante toda la extracción del rodete. Esta concentricidad permite que el deslizamiento sea suave y favorezca la extracción, sin agarres ni atasques que darían tanto al eje como al rodete. De igual manera, cuando se lleva a cabo la inserción de un rodete, este movimiento también es vertical, síncrono y equilibrado.In this way, the shot made by the chains when carrying out the extraction of the impeller is vertical, synchronous and balanced, so that the impeller always remains perpendicular to the axis of rotation of said impeller, and therefore the impeller hole where it goes provided the axis is concentric to said axis during the entire extraction of the impeller. This concentricity allows the sliding to be smooth and favors extraction, without grips or jams that would give both the shaft and the impeller. Similarly, when the insertion of an impeller is carried out, this movement is also vertical, synchronous and balanced.
Opcionalmente, el dispositivo comprende unos medios de vibración acoplables al rodete que permiten que durante la extracción o inserción del rodete se mejore el deslizamiento entre eje y rodete de forma que se evita que siempre sea el mismo punto del eje el que está en contacto con el rodete, evitando así los gripajes entre rodete y eje y el arrastre de material por parte del rodete.Optionally, the device comprises vibration means that can be coupled to the impeller so that the sliding between the impeller and the impeller is improved during the extraction or insertion of the impeller so that it is always avoided that it is always the same axis point that is in contact with impeller, thus avoiding the seizures between impeller and shaft and the drag of material by the impeller.
El dispositivo comprende un bastidor donde se encuentran acoplados los medios de transmisión del movimiento de elevación y/o descenso y los medios de accionamiento del movimiento de elevación y/o descenso.The device comprises a frame where the transmission means of the lifting and / or lowering movement and the actuating means of the lifting and / or lowering movement are coupled.
El dispositivo de extracción e inserción de rodetes para bombas verticales multicelulares de la presente invención es autoportante, de manera que se pueden llevar a cabo las operaciones de extracción e inserción de rodetes in situ, en el mismo pozo donde se encuentra dispuesta la bomba. Para ello, el dispositivo comprende además unos medios de acoplamiento al eje de giro de los rodetes, de manera que es autónomo en lo relativo a su soportación y actuación, evitando en uso de grúas para las operaciones de extracción. Al realizarse en el mismo pozo de la bomba no es necesario disponer de grande instalaciones o adecuar zonas específicas, permitiendo sustanciales ahorros de tiempo y costes, así como de espacio.The impeller extraction and insertion device for multicellular vertical pumps of the present invention is self-supporting, so that the operations of extraction and insertion of impeller in situ can be carried out in the same well where the pump is arranged. For this, the device further comprises coupling means to the axis of rotation of the impellers, so that it is autonomous in relation to its support and performance, avoiding the use of cranes for extraction operations. When carried out in the same pump well, it is not necessary to have large facilities or to adapt specific areas, allowing substantial savings in time and costs, as well as space.
Finalmente, otras de las ventajas son las asociadas al aspecto radiológico. Preferente el dispositivo de la presente invención es aplicable a bombas verticales multicelulares que se encuentran dispuestas en centrales nucleares donde las bombas son materialFinally, other advantages are those associated with the radiological aspect. Preferably the device of the present invention is applicable to multicellular vertical pumps that are arranged in nuclear power plants where the pumps are material
radioactivo. Esta categoría hace que su transporte y manipulación, presente ciertos inconvenientes. Dado el riesgo de irradiación y de contaminación por la manipulación de las bombas en sus labores de transporte y mantenimiento, el dispositivo hace que sea innecesario el transporte de la bomba completa. Además, dado que la bomba 5 permanece en su pozo durante las labores de extracción de rodetes, añade un blindaje adicional. De esta forma este dispositivo constituye una herramienta que reduce dosis a los trabajadores radiológicamente expuestos y los posibles riesgos de contaminación de equipos y maquinas durante el transporte y mantenimiento.radioactive. This category makes its transport and handling present certain drawbacks. Given the risk of irradiation and contamination due to the manipulation of the pumps in their transport and maintenance work, the device makes the transport of the complete pump unnecessary. In addition, since the pump 5 remains in its well during the impeller extraction work, it adds an additional shield. In this way, this device constitutes a tool that reduces doses to radiologically exposed workers and the possible risks of contamination of equipment and machines during transport and maintenance.
