Definitions
- Cascade control of lift pumps is achieved by means of level sensors placed in the sump and connected to an electrical box.
- the order is made through electronic or electromechanical circuits that manage information in from level sensors and internal pump controls.
- the Lifting unit start-up and shutdown orders pass through the pump motor supply wires.
- the electrical control box is generally installed near the sump or in a separate room.
- the electrical cables are connected to the pump via waterproof wall bushings or connectors (waterproof or overmolded).
- the present invention overcomes the drawbacks mentioned above by a submersible pump unit, which does not require for its assembly that a simple electrical connection operation without therefore that a experienced electrician is required and has to make adjustments and read a connection diagram for an electrical box that is difficult to understand at all other than him.
- Claim 4 defines a control device according to the invention.
- the control device is supplied with current electric via a power cable and has a signal generator, which according to an indication provided by the detector level, sends a signal via the power cable likely to be received by another pump unit according to the invention when this other group is connected to the power cable.
- the device control of the first pump can thus, by carrier current, give instructions to the control devices of the second pump, make it know that it is working or not working or that it is in good condition, and reciprocally receive the same information from the control device of the second pump.
- the detector is fixed to the control device by the sealing means which consist of resin, the same mass of which also coats the level detector which can be capacimetric type. It can also be a radio frequency detector.
- Two groups 1, 2 motor pumps are immersed in a tank C submersible.
- the two groups are identical.
- Each group includes a motor 3 driving an impeller 4.
- the motor is surrounded by an envelope 5 impermeable to the liquid to be conveyed contained in the tank C.
- On the lateral face of the casing 5 is fixed a control device 6 which is coated in liquid tight resin to be transported.
- This device 6 is integrated by being coated in the same resin with a capacitance level detector 7.
- the electrical control device 6 which consists of a circuit board printed is connected by a cable 8 to a power supply network 9 electric.
- the pump set comprises a discharge pipe 10 and a suction port 11.
- the pump set 1 is connected by cable 8 and the network 9, as well as by a cable 12, to the other pump unit 2.
- the detector 7 is connected by a conductor 13 to a signal generator 14.
- the signal generator 14 is likely to send signals over cable 8, network 9 and, cable 12 to group 2.
- the TDA integrated circuit can be used 5051 A available from the company Philips Semiconductors.
- the control device 6 is connected by a conductor 15 to the motor 3.

Abstract
Description
Claims (4)
- Groupe motopompe submersible, comprenant un moteur (3) entraínant un impulseur (4), une enveloppe (5) étanche au liquide à véhiculer pour le moteur (3) et un dispositif (6) électrique destiné à commander le moteur (3) en fonction du niveau du liquide dans la cuve (C) dans laquelle se trouve le groupe, niveau qui est détecté par un détecteur (7) de niveau, le dispositif (6) de commande étant muni de moyens d'étanchéité le protégeant de tout contact avec le liquide de la cuve et étant fixé sur l'enveloppe (5) du moteur (3), caractérisé en ce que le détecteur (7) est relié au dispositif (6) par un conducteur électrique et est fixé au dispositif (6) de commande par les moyens d'étanchéité.
- Groupe suivant la revendication 1, caractérisé en ce que les moyens d'étanchéité sont constitués de résine dans laquelle le dispositif (6) de commande est enrobé.
- Groupe suivant la revendication 2, caractérisé en ce que le détecteur (7) est enrobé au moins partiellement dans la même résine.
- Dispositif électrique de commande enrobé dans de la résine pouvant être utilisé pour le groupe suivant l'une des revendications 1 à 3, caractérisé en ce que le détecteur (7) de niveau est enrobé au moins partiellement dans la même résine.
