Definitions

  • the invention relates to a method for operating an electronically controlled pump unit having the features specified in the preamble of claim 1 and an electronic control of an electric motor driven centrifugal pump assembly with the features specified in the preamble of claim 9.
  • Modern pump units in particular electric motor driven centrifugal pump units have an electric motor, which is preceded by a converter / frequency converter, so that the pumps can be operated in wide speed ranges and thus cover a comparatively large power range.
  • a converter / frequency converter for circulating pump units, it is, for example, state of the art to drive the pump at any constant speed, but also to control the operation according to predetermined pump curves.
  • Most regulations are provided, which are operated by means of hydraulic sensors or optionally only based on the electrical values of the engine, so heating circulation pumps can be operated for example with constant pressure curves, with constant-flow curves, with proportional pressure curves or the like.
  • booster pumps not only the desired delivery pressure is set, but also the switching points at which another pump is switched on or off.
  • the invention has the object, a method for operating an electronically controlled pump unit in such a way that the above problems are avoided if possible.
  • the electronic control of an electric motor driven centrifugal pump assembly is to be adapted to carry out such a method.
  • the inventive method for operating an electronically controlled pump unit wherein in an electronic Control adjustment parameters of the pump to adapt to the hydraulic requirements of the local installation situation are adjustable and are registered in the operating data of the pump unit during operation, characterized according to the invention in that is checked after a predetermined time based on the registered operating data, if the pump unit can be operated in a lower energy range or at least to check whether all adjustment parameters have not been changed compared to a default and then if it is determined that the pump unit can be operated in a lower energy range or that the adjustment parameters compared to the default so far have not been changed, a signal for changing the setting parameters is issued.
  • the method should preferably be automated, that is to run automatically, in which it is implemented in the electronic control system, as will be described below.
  • the basic idea of the invention is to carry out a check after a predetermined time, which verifies either by means of the operating data registered within this time interval whether the pump unit can be operated in an energy-favorable range or if this test can not be carried out or not leads to a clear result that is at least checked whether the setting parameters of the pump unit against a default ever have been changed, and then to deliver a signal from which it is recognizable that a change in the setting parameters should be at least checked.
  • Pump unit can in principle be any electric motor-driven pump with an electronic control, in which the setting parameters of the pump To adapt to the hydraulic requirements of the local installation situation are changeable. These are typically single-stage or multistage centrifugal pumps controlled by a converter / frequency converter. Pump unit within the meaning of the invention, however, may also be a number of individual pump units, which are operated by a common control, as is the case for example in pressure boosting systems (eg booster pumps).
  • pressure boosting systems eg booster pumps
  • the emitted signal can be formed, for example, for controlling a control unit provided on the pump unit, for emitting an audible alarm or for transmitting a corresponding data set to a cloud-based database or a server of the manufacturer and / or operator of the pump unit.
  • the inventive method is conveniently started with installation of the pump unit, then the factory default of the pump unit is the default. Then, it is checked after a predetermined time, whether this factory default has been changed or not and delivered in the case of a non-change the corresponding signal.
  • the pump unit it is more favorable if it is checked after a predetermined time based on the registered operating data, if the pump unit can be operated in a lower energy range.
  • the control side anyway available and on the other hand hydraulic operating data of the pump, in particular the pressure and / or flow be used. hereby Without further data, it is possible to analyze the energetic behavior of the pump unit.
  • the resulting from the hydraulic operating data hydraulic power is set in proportion to the electrical power of the engine to thereby determine the efficiency of the unit.
  • the power of the electric motor is the part of the control electronics available, from the hydraulic data is usually a pressure, typically the pressure applied by the pump differential pressure sensorially available, so that in connection with the motor side also available speed, the hydraulic power can be determined can.
  • the data of a flow sensor can be used for this purpose.
  • the hydraulic power is known to result from the product of differential pressure, flow rate, the density of the fluid and the gravitational acceleration.
  • the efficiency of the pump unit can be determined by energetic evaluation of the operating data with these data at a point or continuously.
  • the operating data are registered at intervals or continuously, that is, recorded and stored in order to perform an efficiency test after the predetermined time. It is expedient to carry out such an efficiency test not only from the first commissioning, but at regular intervals.
  • limit values whereby only an undershooting and exceeding of these limit values is to be registered or the temporal course of the undershooting and overshooting.
  • the pump unit determines its efficiency every six minutes, ie the ratio between hydraulic power and electrical power. If the limit has been set to a maximum of 30%, then only the operating points for which the efficiency factor is less than 0.7 are to be registered is.
  • the number of total operating points to be considered is then given by the predetermined time divided by six minutes.
  • the inventive method can not only be used to force an energetically favorable operation of the pump unit, but can also be used to determine a significant under- or oversizing of the pump unit and display.
  • the inventive method can lead to an automatic adjustment of the set parameters of the pump unit, in particular when an Internet connection of the pump unit, if not only the transmission and registration of the operating data of the pump unit via an Internet-based network, but after a network-side verification, a corresponding adjustment of the setting parameters are initiated can.
  • this requires not only a data connection of the pump set to the Internet-based network, but also the possibility of changing the operating parameters over this network.
  • a data set with correspondingly adjusted setting parameters can be made available for download on the network side, which the service technician downloads, for example, to his smartphone and then reads into the electronic engine control on site.
  • the process of checking the efficiency of the pump set is performed continuously throughout the operating time. In view of the then to be registered and processed large amount of data, however, it will be useful in practice to check after first use within a relatively short time, if the pump unit runs energetically favorable and then later check this at longer intervals. In that regard, it is advantageous to the predetermined time in which the registration the operating data takes place between one hour and seven days.
  • the energy efficiency test may be sufficient after a time interval has elapsed.
  • a time interval is typically between six months and five years, but may also be shorter in individual cases.
  • the inventive method can be implemented in existing pump units typically by a software update in the electronic engine control. However, then the signal output is bound to the hardware-specified options of the pump unit. In the simplest form, therefore, when the pump set has no network connection, in particular no internet access, an indicator, for example a red indicator light or a yellow flashing light is activated and alternatively or additionally emit an acoustic signal so that anyone who is in the vicinity of the pump unit , is aware that there is obviously a need for action here.

  • the inventive electronic control of an electric motor driven centrifugal pump assembly has means for adjusting Setting parameters for adapting the pump set to the hydraulic requirements of the local installation situation.
  • Setting parameters for adapting the pump set to the hydraulic requirements of the local installation situation.
  • These can be formed by a button / switch / touchscreen on the unit itself, with which the setting parameters can be changed, for example by selecting appropriate control curves or pressure / flow setpoints.
  • such means may also be wireless, for example by means of a mobile computer, typically smartphones or tablets, on which runs a corresponding software application with which these data can be entered and transmitted wirelessly to the electronic controller.
  • These means can also be formed by transmitting corresponding settings via the network in the case of network connection of the electronic control system.
  • the controller itself is designed to register or forward operating data of the pump unit.
  • the inventive method including registration and evaluation of the registered data within the electronic control of the pump unit or at least partially via a network-linked server, with the electronic control is in data connection.
  • the electronic control of the pump unit is designed to determine for itself whether an adjustment of the adjustment parameters against a registered setting has been made after a predetermined time and to automatically emit a signal if the setting has not been made. Basically, such a review at regular intervals automatically by the controller or constantly.
  • this predetermined time first runs from the startup of the controller and the registered setting the factory Setting is. This ensures that, when the pump unit is installed after delivery by the manufacturer at its destination and connected to the electrical supply network, is at least monitored immediately after this initial commissioning, whether the adjustment parameters have been changed from the factory settings or not. If the latter is not the case and the signal requesting adjustment of the setting parameter is output, it can be assumed with high probability that the pump unit is running in an energy-unoptimized area, since, after installation and commissioning, no adjustment of the setting parameters has taken place.
  • the electronic control is further adapted to automatically determine whether the pump unit is operated in an energetically favorable range or not.
  • the memory and arithmetic operations required so far are more complicated, which is why they can advantageously also be made externally via a network.
  • the controller advantageously has an interface to a network, preferably to an Internet-based network.
  • Such an interface may be wired, for example, designed as a LAN connection, but is designed particularly advantageous for wireless data transmission, for example by means of WLAN or mobile phone connection.
  • the setting parameters are stored in a file of the controller, and that only the change of this file is monitored.
  • File in the context of this invention may also be a group of files or a folder, it is crucial that the monitoring can be done without specific monitoring of the setting parameters themselves, but in a simple way by monitoring the file, which, if changed a modified date or has another characteristic.
  • the adjustment parameters of the electronic control are advantageously one or more of the controlled variables such as flow rate, delivery pressure, rotational speed, power, wherein the hydraulic control variables delivery rate and / or delivery pressure are typically adjustable in the form of control curves.
  • a pump unit 1 is shown, a so-called booster pump, which is composed of three parallel-connected centrifugal pumps 2, which are each driven by a frequenzumrichtermiken electric motor 3, which promote from a common suction line 4 in a common pressure line 5.
  • the pump unit 1 has a higher-level electronic control 6, in which adjustment parameters, in particular the delivery pressure and the connection and disconnection points of the individual pumps can be entered.
  • This electronic controller interfaces with a network that is cloud-based.
  • the controller 6 is equipped with a WLAN module and with a mobile radio module, via which it is wirelessly connected to the network of the pump manufacturer 7 via the Internet 8, that is, the "cloud”.

  • the smartphone 9 is also connected via its radio interface with the Internet 8 and thus the network of the manufacturer 7.
  • the electronic control 6 is designed to check after a predetermined time after starting the operation of the pump unit 1, whether the setting parameters have been changed from the factory settings. These parameters are stored digitally in a file of the controller 6, the controller 6 monitors the storage date of the file. From the first commissioning on a timer is running, for example, is set to 72 hours, so that after this predetermined time is checked whether the date of the file has changed or not. If this is not the case, a signal is emitted, namely to the controller 6 itself to activate a warning light 11, which emits a flashing signal as an indication that the pump unit 1 has not yet been set.

  • the service technician 10 receives via the network 8 not only the indication that the pump unit 1 is to be configured with regard to its setting parameters, but also the location data and, if available, the downloadable from the network 8 data to adjust the setting parameters.
  • the electronic control 6 has a further function with which the operating points are recorded during the operation of the pump unit at intervals of three minutes and these are evaluated with regard to their energy efficiency, as described with reference to FIG Fig. 2A to C in the following is explained:
  • the Fig. 2A shows a typical pump curve of a pump unit, in which the delivery head is plotted against the flow rate.
  • the delivery head is the differential pressure between the pump inlet and the pump outlet, the delivery rate is the delivered volume flow per unit time.
  • the basis of Fig. 2A schematically illustrated pump curve represents a centrifugal pump at a constant Speed represents the Fig. 2B shows the electric power P of this pump unit in dependence of the flow rate.
  • the pump unit on a variety of different such pump curves according to FIGS. 2A and 2B be driven, as indicated by Fig. 2C showing three such curves ⁇ 1, ⁇ 2 and ⁇ 3 representing different speeds.
  • These curves represent the efficiency n as a function of the delivery rate at a speed.
  • the efficiency is the quotient of hydraulic power and electrical power, so ideally one.
  • the electrical power is determined by the recording power, that is, the product of current and voltage of the driving electric motor or the driving electric motors and is available in the data 6 in the controller.
  • the hydraulic power results from the product of flow rate, head, density and gravitational acceleration. It can be calculated by differential pressure and flow sensors.
  • the electronic control now checks after a predetermined time, the efficiency in the operating points of the pump based on the previously determined effectiveness curves, either determined during operation or targeted approached. It can now be based
  • the operating points are determined with temporal correlation, whether they are in the BEP's or outside. It is expediently based on a limit value of, for example, 30%, so that it is only considered how many of the operating points are outside this 30% limit and how many within. Those outside this limit are in Fig. 2C represented in group M.
  • the electronic control 6 is thus able to check whether the pump unit can be moved in a more energetically effective range by changing the setting parameters. If this is the case, the controller 6 sends a corresponding signal to the network, so that the manufacturer or operator side receives a request to change the setting parameters.
  • the suitable parameters for the pump set manufacturer can be specified by the manufacturer and transmitted wirelessly via the network to the smartphone 9 of the operator 10, which then transmits them to the electronic control unit 6 of the pump unit 1 or even selected and set by the operator.
  • Fig. 2C the operating points are shown in an area M which is outside the 30% of the BEPs. It is therefore shown that eight of the ten operating points are outside the 30% range and thus 80% of the operating points fall below the specified efficiency limit range. In this case, an adjustment of the setting parameters is required.
  • a first step 15 the efficiency curves of the pump unit are generated. These can either be targeted or during operation for different flow rates in Depending on the speed of the motor side and thus control side is always known to be determined. Since the curves are never complete, either the pump set must be driven or interpolated to complete the complete curve. In practice, it is sufficient to determine the BEPs that result for each speed. Once this data has been collected, the efficiency test of the pump can be done during operation. It is understood that these methods initially overlap in time, but this is not a problem.
  • step 16 If, after a time interval of, for example, six months or one or two years after the pump is started up and the first check, the efficiency monitoring is to run again, this starts in step 16 after the timer expires, corresponding to the set time of six months, one or two years after the timer Initial check of the pump unit.
  • the efficiency of the current operating point of the pump unit is calculated and stored at a previously determined time interval of, for example, ten minutes. After expiration of a predetermined time of, for example, 48 hours, this calculation and storage of the efficiency in the operating points in the third step 17 is ended.
  • the distribution of the operating points in terms of their efficiency in each case based on the BEP is then evaluated on the control side. If a predetermined percentage of the operating points, for example more than 60% of the operating points, falls below the BEP by more than 30%, then a signal is emitted in the fifth step 19, depending on the evaluation result, to change the setting parameters or also the pump by a smaller one or replace larger ones.
  • the method may also be restarted only after a predetermined time interval, so that the pump unit is effectively monitored for efficiency over its entire service life. If, after signal delivery in the fifth step 19, the setting parameters are changed, the method is also resumed in the second step 16, whereas when replacing the pump, the method begins again with the first step 15.
