Definitions

  • the invention relates to a pump unit for high-pressure cleaning and disinfection systems, consisting of a pump and motor.
  • a pump is usually driven by an electric motor.
  • the grading of the gear upstream of the pump (toothed or V-belt drive) or the nominal speed of the drive motor directly coupled to the pump depends on the permissible speed of the pump.
  • maximum outputs are often required, which - depending on the output requirement - should be downgraded for economic reasons. For example, the max. Pump output "100", the min. For economic reasons, the pump output should be interpreted as "50". In practice, this means that two complete pump units, each with an output of "50", are required. These are connected in parallel.
  • the pump sets are switched on either individually or together. In the latter case, the individual services add up to a total service of "100".
  • the invention has for its object to provide a pump unit of the generic type which the pump output is changeable.
  • a pump unit for example, an output of "100" or "50” should be possible.
  • the invention proposes that the pump unit for controlling different pump outputs is equipped with a pole-changing motor (two-stage motor). This configuration ensures that the number of pump units required can be reduced for different pump outputs. If up to now 10 pump units were required in a large-scale system, half of the pump unit according to the invention can be used. As a result, the costs for the purchase of the required pump units are considerably reduced. Furthermore, a considerable saving in energy is achieved.
  • the pump capacity can be halved by the pole-changing motor.
  • Such pump units are most needed in practice.
  • each pump can interact with a pole-changing motor. This is recommended for economic reasons.
  • a number of pump units which are preferably connected in parallel, can be combined to form one structural unit.
  • the pump assembly 10 consists of a pole-changing motor 11 and a pump 12.
  • the motor 11 drives the pump 12.
  • the max. Output or the output of the pump (11) reduced by 50%.
  • FIG. 2 shows the second exemplary embodiment.
  • five pump units 10 are combined in parallel via pipes 13, 14 to form a unit 15.
  • the reservoir for the pumping liquid bears the reference number 16.
  • the pumps 12 draw in the pumping liquid via the pipe 14 and feed it through the connecting pipes 17 to the main pipe 1, which is connected to the extraction point to which the individual spray guns are connected.
  • the assembly 15 is equipped with an electrical control, not shown, which switches the individual pump units 10 on or off. If, for example, only one spray gun is actuated, only one pump unit 10 is switched on via the electrical control device. In the event that ten spray guns are needed, the remaining four pump units 10 are switched on via the electrical control device.
