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 supply wires for pump motors.
  • 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 has to intervene and has to make adjustments and read a connection diagram for an electrical box that is difficult to understand at all other than him, while having good automatic operation of a cascade of pumps.
  • a submersible motor pump group having the characteristics of the preamble of claim 1 is known for example from the disclosure DE 295 08 802 U.
  • the submersible motor pump group according to the invention is defined in claim 1.
  • the device control is supplied with electric current via a cable power supply and includes a signal generator, which according to a indication provided by the level detector, sends, via the power cable, a signal outside the control device, preference likely to be received by another following pump group the invention when this other group is connected to the power cable.
  • the control device of the first pump can thus, by carrier current, give instructions to the control device of the second pump, make it known 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 and each control device can control its pump accordingly.
  • 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 submersibles.
  • the two groups are identical.
  • Each group includes a motor 3 driving an impeller 4.
  • the motor is surrounded by an envelope 5 impervious 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 embedded 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 unit 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 capable of sending signals via cable 8, network 9 and, cable 12 to group 2.
  • generator 14 it is possible to use the integrated circuit TDA 5051 A available from the company Philips Semiconductors .
  • the control device 6 is connected by a conductor 15 to the motor 3.
