Definitions

  • the invention relates to a pump unit with the features specified in the preamble of claim 1.
  • Pump units of the type mentioned at the outset are known in numerous designs; today, they are used, for example, as heating circulation pumps.
  • the miniaturization in the electronic field has made it possible for electronic speed controllers to be integrated in the pump unit, which enable the pump to be operated in characteristic maps.
  • electronic control is assigned to the speed controller.
  • the desired operating points of the pump unit can be preset via an electronic control integrated in the pump unit via a switch accessible from the outside on the pump housing. It has proven useful to specify various control variables or control characteristics, each of which enables pump operation to be carried out as required and which can be preselected by means of appropriate switches on the outside of the pump unit. Depending on the switch position, the pump set can be operated with different control modes, depending on the requirement profile.
  • the object of the present invention is to design a generic pump unit with structurally simple means which are inexpensive to produce and operate reliably in such a way that the aforementioned disadvantages can be avoided as far as possible or at least largely.
  • the invention therefore provides a wireless mobile remote control for the pump unit, with which at least a desired control variable can be set. In practice, this has considerable advantages.
  • the unit can also be arranged in places that are difficult to access without endangering operability. Costly and fault-prone wiring is not necessary. With appropriate handling of the transmitter, incorrect operation can largely be ruled out by the transmitter being accessible only to the specialist and being kept under lock and key. With appropriate design of the transmission type (radio), it is even possible to control or operate different pump sets from a central location without additional wiring being required.
  • connection module for receiving a measuring device for the electrical or hydraulic operating variables of the motor or pumps to the pump unit and releasably on this connecting module from the outside a further registration device for storing and displaying operating variables to be releasably attached and to provide a wireless transmission of data between the connection module and the further releasable module, but here the wireless transmission only serves for electrical safety, otherwise this pump unit has all the disadvantages that were initially explained with reference to the prior art, of which the present invention is based on.
  • the pump unit not only has a receiver, but also a transmitter, since then not only transmits manipulated variables to the unit, but also wirelessly operating data of the unit to an external receiver can be transmitted. It goes without saying that it is expedient to integrate the external transmitter and the external receiver in a common device with which the pump unit can be operated and checked. In this way, an external operating and control unit of the pump unit is formed.
  • Such an operating and control unit expediently has a display for displaying the transmitted operating data, so that the operator can check the corresponding pump unit at a glance and also immediately receives repercussions about the changes made to his settings.
  • Such displays can also be found on modern pump units on the unit itself.
  • the mobile structural unit (control unit) provided according to the invention as an operating and control unit then has the advantage that a corresponding display on the pump can be omitted.
  • the operating and control unit can preferably also have a printing or storage unit for recording operating data and an interface for connecting a printer or other data memory.
  • a printing or storage unit for recording operating data and an interface for connecting a printer or other data memory.
  • Such a device is particularly useful if data is to be recorded reliably over a long period of time, as is required, for example, when searching for faults in the system which only occur sporadically is.
  • operating and control units according to the invention are issued with different access authorizations, so that the operator of a system can, for example, only make the settings on his operating and control unit that have previously been released by the expert while the Operating and control unit of the maintenance personnel all settings can be carried out.
  • an electric motor-driven pump unit 1 is shown, as it can be used for example in heating systems as a circulation pump.
  • the control electronics and the speed controller in the form of a frequency converter - these components are usually arranged in the terminal box of the unit - are designated by 2.
  • the reference number 3 identifies the transmission and reception electronics upstream of the control electronics, insofar as it is arranged on the aggregate side.
  • the transmission and reception electronics communicating with the transmission and reception electronics 3 of the pump unit 1 is arranged within a mobile assembly 4 (control unit) in the form of an operating and control unit.
  • the arrows 5 and 6 symbolize the wireless data flow from the operating and control unit 4 to the pump unit 1 and vice versa.
  • the pump-side transmitting and receiving part 3 has an infrared transmitter 7 and an infrared receiver 8, to which an infrared transmitter 9 and an infrared receiver 10 are assigned in the operating part 4.
  • the control unit 4 has a numerical input field 11, via which number combinations can be entered, to which corresponding control commands are assigned, specifically via the converter module, designated 12 in the transmitting and receiving electronics 3, which converts the output signal of the IR receiver 8 into a for the Control electronics 2 understandable signal converts.
  • the signal connection between the transmitting and receiving electronics 3 and the control electronics 2 is identified by 13.
  • signals can be sent to the infrared receiver 8 by means of corresponding numerical inputs via the input field 11 by means of the infrared transmitter 9 the converter module 12 are decrypted or converted into a signal with which characteristic curves can be selected directly in the control electronics 2.
  • a control unit can also be provided in the operating part 4, with which a data protocol can be printed out.
  • the control unit has a memory module 16 connected in parallel with the display 15, which stores the received data, not only the current value, but also the operating state over time. This data can be queried via an interface 17 or processed in an electronic data processing system.
  • a signal connection 18 is provided within the control unit 4, which also supplies the output data of the converter module 12 directly to the infrared transmitter and thus to the control unit. In this way, the signal transmission 5 can be controlled, and the corresponding can also be provided for the signal transmission 6.
