Definitions

  • the present disclosure relates to a pump system with one or more pumps and a pump control method therefor.
  • This is preferably one or more wet-running circulating pumps, which are designed as single-stage or multi-stage centrifugal pumps for pumping water.
  • CMOS complementary metal-oxide-semiconductor
  • PLCs programmable logic controllers
  • US 9,670,918 B2 describes, for example, a booster system with a PLC that tries to determine the optimal switch-on parameters for the pumps.
  • the EP 0 711 920 A1 and the WO 00/03142 each describe an electronics housing with motor control and pressure sensor arranged externally to a pump unit.
  • the present disclosure provides a pump system and pump control method that eliminates the need for a PLC or external electronics package for motor control, thereby reducing system complexity and cost.

  • the sensor is arranged externally from a housing for the engine control.
  • the pump system disclosed herein thus uses the sensor electronics located in the sensor in order to save on the complex and cost-intensive SPS and to command the pump(s) directly from the sensor.
  • the "motor control” is intended here to have those power electronic components that control the working current through the coils of the drive motor, such as a frequency converter.
  • the term "command” is intended to mean here in the sense of a control that command signals are sent from the pump controller to the engine controller, which determine the mode of operation of the drive motor, for example an on and / or off signal, a target speed and / or target power consumption.
  • the sensor electronics can also provide measurement signals, the provision of measurement signals should not be misunderstood here as commanding, even if a pump controller makes the operating mode of the drive motor dependent on a measurement signal.
  • the present disclosure is therefore to be distinguished from systems in which a pump controller outside of the sensor receives a measurement signal from the sensor and makes the mode of operation of the drive motor dependent on a measurement signal.
