Abstract

The motor/pump group, includes a motor (3) driving an impeller (4), a liquid sealed motor casing (5) and an electrical control unit (6) designed to control the motor as a function of the liquid level in a volume (C) in which the motor/pump group is placed. Liquid level is detected by a sensor (7). The control unit is sealed to prevent ingress of liquid and is fitted to the motor casing. The unit is supplied with electrical current via a cable (8), and it includes a signal generator (14), which, on receipt of a signal from the sensor, sends through the cable to another similar motor group.

Description

Grupo motobomba sumergible con dispositivos de mando fijado en la envolvente del motor.Submersible motor pump group with devices command fixed on the motor envelope.

El control de cascadas de bombas de extracción (de 2 a "n" bombas) se realiza con intermedio de captadores de nivel situados dentro del pozo y conectados a una caja de control eléctrico. El mando es realizado por intermedio de circuitos electrónicos o electromecánicos que gestionan las informaciones que proceden de los captadores de nivel y de los controles internos de las bombas. Las ordenes de puesta en marcha y de paro de los grupos de extracción pasan por los hilos de alimentación de los motores de las bombas. La caja de control eléctrico está instalada en general en las proximidades del pozo o en un local separado. La conexión de los cables eléctricos a la bomba se realiza con intermedio de travesaños de paredes estancas o conectores (estancos o sobremoldeados).Cascade control of extraction pumps (from 2 to "n" pumps) is carried out through intermediate collectors level located inside the well and connected to a control box electric. The command is done through circuits electronic or electromechanical that manage the information that they come from the level sensors and internal controls of the bombs. The start-up and stop orders of the groups of extraction pass through the threads of feeding of the motors of the bombs. The electrical control box is installed in general in the vicinity of the well or in a separate room. The connection of The electrical cables to the pump are made through watertight wall crossbars or connectors (waterproof or overmolded).

Todos los componentes captadores, bombas de extracción, caja de mando, están separados entre si, por lo que sus conexiones se deben realizar por un electricista que tenga en cuenta las normas de instalación y seguridad.All collector components, pumps extraction, control box, are separated from each other, so their connections must be made by an electrician who takes into account Installation and safety regulations.

La complejidad de las instalaciones se traduce frecuentemente por dificultades de funcionamiento de los dispositivos o un mantenimiento difícil.The complexity of the facilities is translated frequently due to operating difficulties of devices or difficult maintenance.

En el documento DE-A-19654892 se describe un grupo motobomba según el preámbulo de la reivindicación 1, en el que el dispositivo de mando y el detector de nivel no están integrados en una única caja de control que se puede adaptar a varios tipos de bomba y ser desmontada en taller de una bomba defectuosa para su montaje en otra bomba.In the document DE-A-19654892 describes a group motor pump according to the preamble of claim 1, wherein the control device and level detector are not integrated in a single control box that can be adapted to various types of pump and be disassembled in the workshop of a defective pump for your mounting on another pump.

La presente invención palia los inconvenientes anteriormente mencionados mediante un grupo motobomba sumergible que no requiere para su montaje más que una simple operación de conexión eléctrica sin que sea necesario un electricista experto ni que se deba proceder a regulaciones y lecturas de un esquema de conexiones de una caja de control eléctrico poco inteligible a otras personas distintas, con la posibilidad de montar la unidad constituida por el dispositivo de mando y el detector de nivel en otra bomba.The present invention palliates the drawbacks previously mentioned by means of a submersible motor pump group which does not require for assembly more than a simple operation of electrical connection without requiring an expert electrician or that regulations and readings of a scheme of connections of an unintelligible electrical control box to other different people, with the possibility of mounting the unit constituted by the control device and the level detector in Another bomb

El grupo motobomba sumergible es definido en las reivindicaciones 1 a 3.The submersible motor pump group is defined in the claims 1 to 3.

No se pretende, tal como se hacia hasta el momento, controlar el motor con ayuda de una caja de control o armario eléctrico que no tenga necesidad de ser estanco puesto que está situado a distancia del motor y, por lo tanto, fuera del líquido a transportar y que se podía adaptar a numerosos tipos de motor siempre que un electricista se pudiera encargar del trabajo de regulación y montaje. Al contrario, el dispositivo de mando se encuentra ahora asociado al motor pero, gracias al hecho de que el dispositivo de control está fijado en fábrica sobre la envolvente del motor, se puede regular el dispositivo de mando en fábrica y aceptar su conexión sin tener que efectuar regulación, puesto que ya ha sido regulado en fábrica. El montaje está extremadamente simplificado. Además, dado que el dispositivo de mando se encuentra ahora en la proximidad inmediata del detector de nivel, los enlaces entre dichos elementos son muy simples, lo que contribuye en gran medida a disminuir la complejidad del conjunto.It is not intended, as it was done until the moment, check the engine with the help of a control box or electrical cabinet that does not need to be waterproof since is located at a distance from the engine and therefore outside the liquid to be transported and that could be adapted to numerous types of motor as long as an electrician could take care of the job of regulation and assembly. On the contrary, the control device is is now associated with the engine but, thanks to the fact that the control device is factory set on the enclosure of the motor, the factory control device can be adjusted and accept your connection without having to make regulation, since It has already been factory regulated. The mount is extremely simplified. In addition, since the control device is located now in the immediate proximity of the level detector, the links among these elements are very simple, which contributes greatly measure to reduce the complexity of the whole.

Preferentemente el dispositivo de mando está alimentado en corriente eléctrica con intermedio de un cable de alimentación y presenta un generador de señales que en función de una indicación facilitada por el detector de nivel envía, por intermedio del cable de alimentación, una señal susceptible de ser recibida por otro grupo motobomba de acuerdo con la invención cuando este otro grupo está conectado al cable de alimentación. El dispositivo de mando de la primera bomba puede, por lo tanto, mediante corriente portante, dar instrucciones a los dispositivos de mando de la segunda bomba, haciéndole saber que funciona o que no funciona o que se encuentra en buen estado, y recibir recíprocamente las mismas informaciones del dispositivo de mando de la segunda bomba.Preferably the control device is powered by electric current through a cable power and presents a signal generator that depending on an indication provided by the level detector sends, by intermediate power cable, a signal that can be received by another motor pump group according to the invention when this other group is connected to the power cable. He control device of the first pump can, therefore, by carrying current, instruct the devices command of the second pump, letting you know what works or what doesn't works or is in good condition, and receive reciprocally the same information of the control device of The second bomb.

Según una forma de realización ventajosa el detector está fijado al dispositivo de mando por los medios de estanqueidad que están constituidos en una resina, cuya masa envuelve el detector de nivel que puede ser de tipo capacimétrico. Éste puede ser también un detector de radio frecuencia.According to an advantageous embodiment the detector is fixed to the control device by the means of tightness that are constituted in a resin, whose mass It wraps the level detector that can be of the capacitometric type. This can also be a radio frequency detector.
