Definitions

  • the invention relates to a method for operating a variable-speed circulating pump, in particular a heating circulating pump.
  • the DE 10 2009 005154 A1 describes a device for connecting an electromotive drive unit to a pump unit and a lantern, which encompasses mechanical connecting means for driving the pump unit by the drive unit and to which the drive unit is connected at least indirectly on one end face and the pump unit on the axially opposite end face, wherein at or Monitoring electronics for detecting the operating state of the pump unit and/or the drive unit are arranged in the lantern.
  • the EP 2 927 501 A1 describes a method for determining and evaluating the installation orientation of a device, in which the current installation orientation of the device is detected by at least one position detector assigned to the device and a control and/or evaluation unit is used to check whether the device may be operated in the detected position orientation.
  • the EP 2 918 836 A1 describes a method for providing at least one piece of information about a pump unit on a controllable display of an electronic system of the pump unit, the information being represented as at least one graphic code and/or encoded as a character string, the graphic code being a matrix code or a flickering bar code .
  • the cause of an excessively high noise level during pump operation can be the pump itself or the chosen installation variant of the pump within the heating circuit.
  • Typical circulating pumps allow several different installation variants in order to have better flexibility with regard to the conditions and space conditions at the installation site. For the fitter, however, it is hardly recognizable in advance which installation variant is the best in terms of operating volume. In the worst case, the operating vibration of the pump falls on the natural frequency of the pump and pipe system, which leads to a significant increase in noise emissions. In this case, changing the installation variant can help.
  • the object of the present invention is therefore to indicate a method for detecting an unfavorable installation variant.
  • variable-speed circulating pump in particular a heating circulating pump
  • a heating circulating pump to expand the pump control with a corresponding routine for detecting an unfavorable installation variant, after which at least one physical pump operating variable is detected by sensors and immediately or is compared indirectly against at least one stored reference value.
  • the result of the comparison can be used to evaluate the installation variant, in particular to determine whether the installation variant is disadvantageous in terms of noise emissions during pump operation.
  • the circulation pump is typically a centrifugal pump.
  • An indirect comparison includes exemplary embodiments according to which the measured variable is first processed further and at least one variable derived therefrom is compared with a suitable reference variable.
  • any physical variable that allows a characterization of the pump behavior i.e. the noise emission
  • Negative effects were already shown in the introduction, which can lead to an unforeseeable increase in noise emissions, in particular the coincidence of the natural frequency of the pump and pipeline system with the operating vibration of the pump. Accordingly, physical quantities that allow a statement to be made with regard to the operating vibration of the pump are particularly suitable.
  • the determination of an acceleration value is proposed, in particular the acceleration of the conveyed medium and/or the acceleration of the driven pump impeller and/or the acceleration of the pump housing.
  • the acceleration value should be recorded as close as possible to the impeller.
  • the acceleration values can be measured using an integrated acceleration sensor in the circulation pump, which is preferably located on the pump housing in the immediate vicinity of the impeller.
  • the metrological detection of the physical pump performance variable used can either take place continuously during pump operation or, however, be limited to a definable measurement interval, possibly with measurement repetitions at random or periodic intervals.
  • the pump controller can issue a visual and/or acoustic signal to inform the end user or fitter of the problems with the installation variant, ideally in combination with a suggestion for a alternative better installation variant.
  • the recorded value of the pump operating variable is initially processed further.
  • the oscillation behavior of the physical operating variable is determined on the basis of the measured physical pump operating variable. To do this, it is necessary for the pump operating variable to be recorded over a certain period of time in order to ultimately be able to draw conclusions about the oscillation behavior of the variable.
  • the vibration behavior is obtained, for example, by means of Fast Fourier Transformation (FFT) from the time profile of the measured acceleration value.
  • FFT Fast Fourier Transformation
  • At least one variable characterizing the determined vibration behavior is compared with a suitable reference value of the characteristic variable stored in the pump controller in order to evaluate the installation variant.
  • the amplitude and/or the frequency of the vibration determined is/are proposed as the characterizing variable. It is particularly preferred in this connection if the vibration amplitude is compared to a reference amplitude and the end user is informed of the non-optimal installation variant if the detected amplitude is higher by a specific amount than the reference amplitude.
  • the reference value or values depend on the current operating point of the pump.
  • the current operating point of a circulating pump is defined by the point of intersection between the system characteristic and the control characteristic of the pump. Since the noise development of the pump depends to a large extent on the selected operating point, proposed according to the invention to define assigned individual reference values for a large number of operating points and to keep them ready in the pump control.
  • the pump control selects the appropriate reference value depending on the currently adjusted operating point and directly or indirectly compares the current measured values with the selected reference value.
  • One or more suitable reference values are generated in advance, ideally during pump development.
  • a reference pump is used within a test field in different installation variants.
  • the reference variable for different operating points is measured and saved for each installation variant. Subsequently, the reference values of those installation variants are selected as final reference values that show the lowest noise emissions in the test bench.
  • the present object is also achieved by a circulating pump, in particular a heating circulating pump, with a variable-speed pump drive and a pump controller, which is suitable for carrying out the method according to the present invention. Consequently, the same advantages and properties result for the circulating pump as have already been explained in detail in advance using the method according to the invention. For this reason, a repeated description is dispensed with.
  • the circulation pump is typically a centrifugal pump.
  • the pump can preferably include at least one acceleration sensor; another sensor that allows the acceleration value to be recorded indirectly is also conceivable.
  • the present invention describes a method for detecting an unfavorable installation variant of a heating circulating pump 10. This method is implemented in the pump control and requires that the pump 10 has an acceleration sensor 11 that detects the acceleration of the pump housing as close as possible to the pump impeller.
  • the pump structure is shown schematically in figure 1 implied.
  • FIG 1 schematically shows the connection of the circulation pump 10 to a building wall 1.
  • the installation site is shown here as a spring-damper system 12.
  • the type of installation has an influence on the stiffness and damper parameters and thus changes the natural frequency and the associated amplitude.
  • the actual implementation of the procedure is based on two preparatory steps.
  • an optimal installation variant is defined.
  • different installation variants are implemented in the test field during the development phase and the vibration behavior and acoustics are recorded at several operating points.
  • one of the variants is evaluated as optimal based on the measurement data.
  • the characteristic values detected by acceleration sensor 11 for describing the vibration state (for example amplitude, frequency) are stored in a matrix at a number of operating points.
  • the state of vibration i.e. the amplitude-frequency diagram of the vibration behavior, is obtained from the time profile of the measured acceleration value using Fast Fourier Transformation.
  • This data is ultimately implemented in the local memory of the pump controller.
  • the method according to the invention is then carried out during pump operation.
  • the pump 10 With its acceleration sensor 11, the pump 10 detects the acceleration of the pump housing over time.
  • the characteristic vibration values are determined by means of Fast Fourier Transformation and with the previously considered optimal compared detected reference values. If the oscillation amplitude in the process is significantly higher than the amplitude previously detected as optimal, the pump 10 will recognize this and inform the user. The user can then use this information to optimize the installation variant of the pump 10 if necessary.
  • FIG. 2 shows the frequency-amplitude diagram determined by means of FFT from the signal curve of acceleration sensor 11 for two different installation variants.
  • Installation variant 2 shows a significantly lower vibration amplitude at certain frequencies than installation variant 1.
