La presente invención se refiere a unas mejoras introducidas en la patente de invención nº 200502108, realizadas sobre diversos aspectos relativos a evitar desgastes excesivos tanto en las paletas como en el estator de la bomba.The present invention relates to improvements introduced in the invention patent No. 200502108, made on various aspects related to avoiding excessive wear both on the vanes and on the pump stator.

La bomba de paletas deslizantes objeto de la mejora comprende un estator y un rotor excéntrico que presenta unas paletas que atraviesan diametralmente el rotor y con capacidad para deslizar diametralmente en el interior del mismo.The sliding vane pump object of the improvement comprises a stator and an eccentric rotor that has some vanes that cross the rotor diametrically and with capacity for slide diametrically inside it.

Caracteriza a las mejoras el hecho de que el deslizamiento diametral de las paletas en el rotor se realiza a través del guiado de las mismas mediante levas situadas en los extremos del eje de giro del rotor de manera que los extremos libres de las paletas siguen el perfil de la pared interna del estator.The fact that the diametral sliding of the vanes on the rotor is performed at through their guidance by means of cams located in the Rotary shaft ends of the rotor so that the ends free of the pallets follow the profile of the inner wall of the stator

Antecedentes de la invenciónBackground of the invention

El antecedente inmediato de estas mejoras lo constituye la patente principal nº 200502108 y de título "Bomba de paletas deslizantes".The immediate history of these improvements constitutes the main patent nº 200502108 and of title "Bomb of sliding vanes. "

La bomba de paletas deslizantes objeto de la patente principal está constituida por un estator y un rotor excéntrico que presenta unas paletas que se caracterizan porque atraviesan diametralmente el rotor deslizando en el interior del mismo. En la realización preferente de la patente nº 200502108 este deslizamiento diametral de las paletas se logra debido al efecto del roce de los extremos de las mismas con la pared interna del estator.The sliding vane pump object of the main patent consists of a stator and a rotor eccentric that presents some vanes that are characterized because diametrically traverse the rotor sliding inside the same. In the preferred embodiment of patent No. 200502108 this Diametral sliding of the vanes is achieved due to the effect of rubbing the ends thereof with the inner wall of the stator

Las paletas se realizan en un material de menor dureza que el estator de la bomba produciéndose un elevado desgaste en las mismas consecuencia de su roce con el estator.The pallets are made in a smaller material hardness that the pump stator producing high wear in the same consequence of its rubbing with the stator.

Este hecho provoca que con mucha frecuencia sea necesario tener que extraer la bomba de su ubicación con el objeto de reponer las paletas desgastadas. Aunque con menor frecuencia, el estator también sufre desgaste debido al roce de las paletas.This fact causes it to be very often it is necessary to have to remove the pump from its location with the object to replace worn vanes. Although less frequently, the Stator also suffers wear due to the friction of the vanes.

La presente mejora resuelve la anterior desventaja mediante un medio alternativo al guiado de las paletas y su correspondiente deslizamiento diametral provocado por el roce de éstas sobre las paredes del estator, de modo que se disminuye así el desgaste producido en las mismas.This improvement resolves the previous one disadvantage through an alternative means to guiding the pallets and its corresponding diametral slip caused by the friction of these on the stator walls, so that the wear produced therein.

Descripción de la invenciónDescription of the invention

La presente invención consiste en una mejora de la bomba de paletas deslizantes divulgada en la patente de nº 200502108.The present invention consists in an improvement of the sliding vane pump disclosed in patent no. 200502108.

Dichas mejoras permiten un menor desgaste de las paletas de la misma así como del estator.These improvements allow less wear of the  pallets of the same as well as the stator.

La bomba de paletas deslizantes divulgada en la patente nº 200502108 comprende un estator y un rotor excéntrico. El rotor presenta unas paletas que atraviesan diametralmente el mismo, de modo que paletas diametralmente opuestas se corresponden realmente con una única paleta. Estas paletas poseen la capacidad de deslizar en el interior del rotor de modo que se retraen o avanzan en función del perfil de la pared interna del estator.The sliding vane pump disclosed in the Patent No. 200502108 comprises a stator and an eccentric rotor. He rotor has blades that diametrically cross it, so that diametrically opposite vanes correspond Really with a single palette. These pallets have the capacity of sliding inside the rotor so that they retract or advance according to the profile of the internal wall of the stator.

La presente mejora se caracteriza porque el deslizamiento diametral de las paletas se realiza a través del guiado de las mismas mediante levas situadas en los extremos del eje de giro del rotor.The present improvement is characterized in that the diametral sliding of the vanes is done through the guiding them by means of cams located at the ends of the rotor axis of rotation

De esta manera se evita que el deslizamiento de las mismas esté gobernado por el roce de los extremos de las paletas con la pared interna del estator lo que produce un desgaste excesivo de las mismas pasando a estar gobernado por un sistema de levas y seguidor situado en los extremos del eje de giro del rotor, de modo que es este sistema el que regula el movimiento de las paletas según el perfil de la pared interna del estator, pero evitando el roce de los extremos de las mismas sobre las paredes de éste.This prevents the slippage of they are governed by the rubbing of the ends of the vanes with the internal wall of the stator resulting in wear excessive of them happening to be governed by a system of cams and follower located at the ends of the rotor's axis of rotation, so it is this system that regulates the movement of vanes according to the profile of the internal wall of the stator, but avoiding the rubbing of the ends thereof on the walls of East.

Para el guiado del deslizamiento de las paletas (2.1, 2.2) se sitúan sendas pletinas (3) en los extremos del eje del rotor (2), véase la figura 2, que disponen de al menos una ranura (3.1) a modo de leva. En esta ranura (3.1) engarza un extremo (4.1) de un seguidor (4) estando el extremo opuesto (4.2) del mismo (4) solidario a una de las paletas (2.1, 2.2). De esta manera al girar el eje del rotor (2) las paletas (2.1, 2.2) describirán el movimiento marcado por la leva (3.1).For guiding the sliding of the vanes (2.1, 2.2) flat paths (3) are located at the ends of the shaft of the rotor (2), see figure 2, which have at least one slot (3.1) as a cam. In this slot (3.1) crimp one end (4.1) of a follower (4) with the opposite end (4.2) thereof (4) in solidarity with one of the pallets (2.1, 2.2). In this way to rotate the rotor shaft (2) the vanes (2.1, 2.2) will describe the movement marked by cam (3.1).

Con el objeto de insertar el correspondiente extremo (4.2) en la paleta (2.1, 2.2), éstas (2.1, 2.2) comprenden unos orificios (5) de entrada del extremo (4.2) del seguidor (4).In order to insert the corresponding end (4.2) on the palette (2.1, 2.2), these (2.1, 2.2) comprise entrance holes (5) of the end (4.2) of the follower (4).

En la figura 3 se representa una realización preferente del seguidor de la leva (4). Este consta de una parte cilíndrica (4.2) destinada a estar situada en los orificios (5) de las paletas (2.1, 2.2) y una parte plana (4.1) destinada a insertarse en la ranura (3.1) de la placa (3).An embodiment is shown in Figure 3 preferred cam follower (4). This consists of a part cylindrical (4.2) intended to be located in the holes (5) of the pallets (2.1, 2.2) and a flat part (4.1) intended for Insert into the slot (3.1) of the plate (3).

En principio al existir en la realización preferente dos paletas (2.1, 2.2), sería únicamente necesario para el correcto funcionamiento la utilización de dos seguidores (4), sin embargo sería también posible el uso de cuatro seguidores (4) con lo que existiría entonces un orificio (5) en cada semipaleta.In principle when existing in the realization preferably two pallets (2.1, 2.2), it would only be necessary for the correct operation the use of two followers (4), however it would also be possible to use four followers (4) with what would then exist a hole (5) in each semi-pallet

Con el objeto de mejorar el deslizamiento del extremo plano (4.1) en la ranura (3.1), el seguidor (4) puede disponer en su extremo de una roldana.In order to improve the sliding of the flat end (4.1) in the groove (3.1), the follower (4) can have at its end a roller.

Es también objeto de la presente mejora un cambio en la cavidad de recepción del líquido o cámara de aspiración de la bomba. Como se comentaba en la patente principal la bomba se dispone totalmente sumergida, en este caso no es necesario la existencia de una tobera específica de entrada de residuos, sino que ésta puede estar constituida por la eliminación de aproximadamente la mitad inferior del estator (2). En este caso para dotar a la bomba de una mayor rigidez estructural el estator (1) y el rotor (2), además de por lo extremos del eje, se encuentran también unidos mediante una fijación (6), situada próxima a la tobera de expulsión de la bomba.It is also the subject of the present improvement a change in the reception cavity of the liquid or chamber of pump suction.
