Definitions

  • the present invention relates to pump units comprising a pump driven by a motor controlled by an electric circuit.
  • the pump set operates without providing the discharge function, for example because the level detection float is blocked or because it is dirty. It can also happen that the pump is clogged. The pump may also continue to operate because it erroneously detects the presence of liquid to be aspirated.
  • the invention overcomes this disadvantage by making it possible to be aware of a malfunction of the pump unit, whatever it may be.
  • means are provided for activating warning means if the given threshold of the current which passes into the electrical control circuit of the motor has been exceeded continuously for a given period of time.
  • the given period of time preferably has a duration greater than the starting time of the motor, during which time the current increases transiently.
  • the time is usually between 30 minutes and 24 hours, preferably between 1 and 6 hours.
  • the pump unit comprises means for measuring the current connected to a comparator comparing the current measured with a reference current and the comparator is connected to a clock to which it sends a signal as long as the threshold is exceeded.
  • the clock sends a signal to the alerting means if it receives this signal beyond the given time.
  • the pump unit comprises a pump 1 driven by an electric motor 2 controlled by an electric circuit 3 powered by a power supply 4 and comprising a high level sensor and a low level sensor.
  • the high level sensor activates the unit when liquid exceeds a high level in the tank where the unit is placed and stops it when the level of the liquid in the tank is lowered. below the low level.
  • a device 5 for measuring the current is connected to a comparator 6 comparing the current measured with a current from a source 7 reference.
  • the comparator has a first output leading to a clock 8.
  • the clock 8 is connected to an alert 9.
  • the current measuring device 5 continuously sends a signal corresponding to a current of an intensity of one ampere to the comparator 6.
  • the activation means 8 may also have the form of software.
