Definitions

  • the invention relates to a method for operating an electronically controlled centrifugal pump unit with the features specified in the preamble of claim 1 and to an electronic control of an electric motor-driven centrifugal pump unit for carrying out this method with the features specified in the preamble of claim 7.
  • Modern pump units particularly centrifugal pump units driven by an electric motor, have an electric motor connected to a power converter/frequency converter so that the pumps can be operated in a wide range of speeds and thus cover a comparatively large range of performance.
  • circulation pump units for example, it is state of the art to drive the pump at any constant speed, but also to control operation according to predetermined pump curves.
  • controls are provided which are operated using hydraulic sensors or, if necessary, only based on the electrical values of the motor.
  • heating circulation pumps can be operated with constant pressure curves, with constant flow curves, with proportional pressure curves or the like.
  • booster pumps not only the target delivery pressure has to be set, but also the switching points at which another pump is switched on or off.
  • EP1614903 A1 A pump known from the prior art is disclosed.
  • the invention is based on the object of designing a method for operating an electronically controlled centrifugal pump unit in such a way that the above-mentioned problems are avoided as far as possible.
  • the electronic control of an electric motor-driven centrifugal pump unit is to be adapted to carry out such a method.
  • the method according to the invention for operating an electronically controlled centrifugal pump unit in which setting parameters of the pump can be set in an electronic control system to adapt to the hydraulic requirements of the local installation situation and in which operating data of the pump unit are recorded during operation, is characterized according to the invention in that after a predetermined time it is checked whether all setting parameters have not been changed compared to a presetting and then, if it is determined that the setting parameters have not yet been changed compared to the presetting, a signal is issued to change the setting parameters.
  • the method should preferably be automated, i.e. run automatically, by being implemented in the electronic control system, as described further below.
  • the basic idea of the invention is to check after a predetermined time whether the setting parameters of the pump unit have ever been changed compared to a preset setting, in order to then emit a signal based on It is clear that a change in the setting parameters should at least be checked.
  • a pump unit within the meaning of the invention can in principle be any electric motor-driven centrifugal pump with an electronic control system in which the pump setting parameters can be changed to adapt to the hydraulic requirements of the local installation situation. Typically, these are single- or multi-stage centrifugal pumps controlled by a power converter/frequency converter.
  • a pump unit within the meaning of the invention can, however, also be a number of individual pump units that are operated by a common control system, as is the case with pressure boosting systems (e.g. booster pumps).
  • the signal emitted can, for example, be used to control an indicator light provided on the pump unit, to emit an acoustic alarm or to transmit a corresponding data set to a cloud-based database or a server of the manufacturer and/or operator of the pump unit.
  • the method according to the invention is started with the installation of the pump unit, then the factory presetting of the pump unit is the default setting. Then, after a predetermined time, a check is made as to whether this factory presetting has been changed or not and, if there has been no change, the corresponding signal is emitted.
  • the registered operating data is used to check whether the pump unit can be operated in a more energy-efficient range.
  • a further development of the method provides for that for the energetic evaluation of the operating data, electrical operating data of the motor, in particular the electrical power of the motor, which is already available on the control side, and hydraulic operating data of the pump, in particular the pressure and/or flow, are used. This makes it possible to analyze the energetic behavior of the pump unit without further data. The hydraulic power resulting from the hydraulic operating data is compared with the electrical power of the motor in order to determine the efficiency of the unit.
  • the power of the electric motor is available from the control electronics, and from the hydraulic data a pressure, typically the differential pressure applied by the pump, is usually available via a sensor, so that the hydraulic power can be determined in conjunction with the speed also available on the motor side.
  • a pressure typically the differential pressure applied by the pump
  • the data from a flow sensor can be used for this purpose.
  • the hydraulic power is known to be the product of the differential pressure, the flow rate, the density of the pumped medium and the gravitational acceleration. This data can be used to determine the efficiency of the pump unit either at specific points in time or continuously by evaluating the energy from the operating data.
  • the limit value has been set at a maximum of 30%, then only the operating points at which the efficiency factor is less than 0.7 are to be recorded. The total number of operating points to be taken into account is then the predetermined time divided by six minutes.
  • the method can not only be used to force the pump unit to operate in an energy-efficient manner, but can also be used to determine and indicate whether the pump unit is significantly under- or over-dimensioned.
  • the process can ideally lead to an automatic adjustment of the pump unit's setting parameters, particularly if the pump unit is connected to the Internet, if not only the operating data of the pump unit is transmitted and recorded via an Internet-based network, but also a corresponding adjustment of the setting parameters can be initiated after a network-side check.
  • this requires not only a data connection of the pump unit to the Internet-based network, but also the possibility of changing the operating parameters via this network.
  • a data set with appropriately adjusted setting parameters can be made available for download on the network side, which the service technician can download to his smartphone, for example, and then read into the electronic motor control on site.
  • the process in which the efficiency of the pump unit is checked is carried out continuously during the entire operating time. In view of the large amount of data that then has to be recorded and processed, however, it is In practice, it may be useful to check within a relatively short time after initial commissioning whether the pump unit is running efficiently in terms of energy and then to check this at longer intervals later. In this respect, it is advantageous to choose a predetermined time period in which the operating data is recorded between one hour and seven days.
  • the method according to the invention can typically be implemented in existing pump units by means of a software update in the electronic motor control.
  • the signal output is then tied to the hardware capabilities of the pump unit.
  • a display for example a red indicator light or a yellow flashing light, is activated and alternatively or additionally an acoustic signal is emitted so that everyone who is near the pump unit is aware that there is obviously a need for action.
  • the signal is transmitted in the form of a data packet via the internet-based network to a server, which informs the manufacturer or the maintenance company that there is a need for action.
  • the data packet contains the location data of the pump unit, as spatial assignment is then possible without access to other personal databases.
  • the electronic control of an electric motor-driven centrifugal pump unit is used to carry out the method according to the invention. It has means for setting setting parameters to adapt the pump unit to the hydraulic requirements of the local installation situation. These can be formed by buttons/switches/touch screens on the unit itself, with which the setting parameters can be changed, for example by selecting corresponding control curves or pressure/flow setpoints. However, such means can also be formed wirelessly, for example by means of a mobile computer, typically smartphones or tablets, on which a corresponding software application runs with which this data can be entered and wirelessly transmitted to the electronic control. If the electronic control is connected to a network, these means can also be formed by transmitting corresponding settings over the network.
  • the control itself is designed to register or forward operating data of the pump unit.
  • the method according to the invention including registration and evaluation of the registered data, can be carried out within the electronic control of the pump unit or at least partially via a network-connected server with which the electronic control is in data connection.
  • the electronic control of the pump unit is designed to determine whether the setting parameters have been adjusted compared to a registered setting after a predetermined time and to automatically emit a signal if the setting has not been made. In principle, such a check can be carried out automatically at regular intervals by the Control or continuously.
  • this predetermined time begins when the control is put into operation and the registered setting is the factory setting. This ensures that when the pump unit is installed at its destination after delivery by the manufacturer and connected to the power supply network, immediately after this initial commissioning it is at least monitored whether or not the setting parameters have been changed compared to the factory settings.
  • the electronic control is further designed to automatically determine whether the pump unit is being operated in an energy-efficient range or not.
  • the storage and computing operations required in this regard are more complex, however, which is why they can advantageously also be carried out externally via a network.
  • the control advantageously has an interface to a network, preferably to an internet-based network.
  • Such an interface can be wired, for example as a LAN connection, but is particularly advantageously designed for wireless data transmission, for example via WLAN or a mobile phone connection.
  • the invention provides that the setting parameters are stored in a file in the control system and that only the change in this file is monitored.
  • a file in the sense of this invention can also be a group of files or a folder; the crucial point is that the monitoring can be carried out without specifically monitoring the setting parameters themselves, but simply by monitoring the file, which has a changed date when changed.
  • the setting parameters of the electronic control are advantageously one or more of the control variables such as flow rate, delivery pressure, speed, power, whereby the hydraulic control variables flow rate and/or delivery pressure can typically be set in the form of control curves.
  • a pump unit 1 is shown, a so-called booster pump, which is made up of three centrifugal pumps 2 connected in parallel, each of which is driven by a frequency converter-controlled electric motor 3, which pump from a common suction line 4 into a common pressure line 5.
  • the pump unit 1 has a higher-level electronic control 6, into which setting parameters, in particular the delivery pressure and the switching on and off points of the individual pumps, can be entered.
  • This electronic control has an interface to a network, which is cloud-based.
  • the control 6 is equipped with a WLAN module and a mobile radio module, through which it is wirelessly connected to the network of the pump manufacturer 7 via the Internet 8, i.e. the "cloud".
  • the electronic control is also equipped with a Bluetooth interface, via which it can communicate with a smartphone 9, via which an operator 10 can query and change the setting parameters available in the control 6.
  • the smartphone 9 is also connected to the Internet 8 and thus to the network of the manufacturer 7 via its radio interface.
  • the electronic control 6 is designed to check after a predetermined time after the pump unit 1 has started operating whether the setting parameters have been changed compared to the factory settings. These parameters are digitally stored in a file in the control 6, and the control 6 monitors the storage date of the file. From the initial start-up, a timer runs, which is set to 72 hours, for example, so that after this predetermined time has elapsed, a check is made as to whether the storage date of the file has changed or not. If this is not the case, a signal is emitted on the control 6 itself to activate a warning light 11, which emits a flashing signal as a sign that the pump unit 1 has not yet been set.
  • a corresponding data signal is sent to the network so that this is noted in the manufacturer's database 7, specifying the GPS data of the location of the pump unit, and at the same time a note appears that this pump unit must be set by a service technician.
  • this required setting can be made via the network itself or via the manufacturer 7 or operator.
  • a service technician is required, i.e. an operator 10 who goes to the pump unit 1 with his smartphone 9 and a software application running on it in order to adjust the setting parameters in the control system 6 accordingly via his smartphone 9.
  • the service technician 10 not only receives the note via the network 8 that the pump unit 1 must be configured with regard to its setting parameters, but also the location data and, if available, the data that can be downloaded from the network 8 for adjusting the setting parameters.
  • the electronic control 6 has a further function with which the operating points are recorded at intervals of three minutes during operation of the pump unit and these are evaluated with regard to their energy efficiency, as can be seen from the Fig. 2A to C as explained below:
  • the Fig. 2A shows a typical pump curve of a pump unit, where the delivery head is plotted as a function of the delivery rate.
  • the delivery head is the differential pressure between the pump inlet and pump outlet, the delivery rate is the volume flow per unit of time.
  • the Fig. 2A The schematically shown pump curve represents a centrifugal pump at a constant speed.
  • the Fig. 2B shows the electrical power P of this pump unit as a function of the flow rate.
  • the pump unit can be operated on a variety of different pump curves according to Fig. 2A and 2B driven, as shown by Fig. 2C , which shows three such curves ⁇ 1, ⁇ 2 and ⁇ 3, which represent different speeds.
  • These curves represent the efficiency ⁇ as a function of the flow rate at a speed.
  • the efficiency is the quotient of hydraulic power and electrical power, ideally one.
  • the electrical power is determined by the input power, i.e. the product of current and voltage of the driving electric motor or motors, and is available in the form of data in the control unit 6.
  • the hydraulic power results from the product of flow rate, discharge head, density and gravitational acceleration. It can be calculated using differential pressure and flow sensors.
  • the electronic control system checks the efficiency at the pump's operating points using the previously determined effectiveness curves, which are either determined during operation or are specifically approached. of the operating points under temporal correlation, whether they are in the range of the BEP's or outside.
  • a limit value of 30%, for example, is used as a basis, so that only the number of operating points outside this 30% limit and how many are within it is considered. The points outside this limit are in Fig. 2C shown in group M.
  • the electronic control 6 is thus able to check whether the pump unit can be operated in a more energy-efficient range by changing the setting parameters. If this is the case, the control 6 sends a corresponding signal to the network so that the manufacturer or operator is prompted to change the setting parameters.
  • the setting parameters suitable for the pump unit can be specified by the manufacturer and transmitted wirelessly via the network to the smartphone 9 of the operator 10, who then transmits them to the electronic control 6 of the pump unit 1, or they can be selected and set by the operator himself.
  • Fig. 2C the operating points are shown in a range M that lies outside the 30% of the BEPs. It is therefore shown that eight of the ten operating points lie 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 Dependence on the speed, which is always known on the motor side and therefore on the control side. Since the curves are never complete, the pump unit must either be controlled to run the complete curve or interpolated. 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 carried out during operation. It goes without saying that these procedures can initially overlap in time, but this is not a problem.
  • the efficiency monitoring is to be run again after a time interval of, for example, six months or one or two years after the pump has been put into operation and the first check, it starts in step 16 after the timer has expired according to the set time of six months, one or two years after the first check of the pump unit.
  • the efficiency of the current operating point of the pump unit is now calculated and saved at a predetermined time interval, for example ten minutes. After a predetermined time of, for example, 48 hours, this calculation and saving of the efficiency in the operating points is terminated in the third step 17.
  • the distribution of the operating points is then evaluated on the control side with regard to their efficiency in relation to the BEP. If a predetermined percentage of the operating points, for example more than 60% of the operating points, fall below the BEP by more than 30%, a signal is emitted in the fifth step 19, depending on the evaluation result, to change the setting parameters or to replace the pump with a smaller or larger one.
  • the process may only be restarted after a predetermined time interval has elapsed, so that the pump unit is monitored for efficiency over its entire operating period. If the setting parameters are changed after the signal is sent in the fifth step 19, the process is also resumed in the second step 16, whereas if the pump is replaced, the process starts again with the first step 15.
