Definitions

  • the invention relates to a method for regulating a pumping station in a hydraulic network which pressurizes a medium to be conveyed to at least one consumer, the pressure being set as a function of the volume flow through the pumping station according to a control curve.
  • the invention also relates to a system for carrying out the method.
  • a method of the type mentioned is from the DE 10 2014 001 413 A1 known.
  • the object of the underlying invention is to provide a method and a system for regulating a pumping station in a hydraulic network, which regulates the pressure of the pumping station as a function of the volume flow as required and in an energy-efficient manner without any loss of comfort.
  • control curve being formed from a plurality of partial pressure curves, each for a volume flow interval of a number corresponding to the plurality Seamlessly adjoining volume flow intervals can be defined on the basis of pressure and volume flow values of the network that have been determined and are to be evaluated at intervals.
  • the control curve is thus defined in sections without any gaps, ie on the one hand for all possible load cases, on the other hand taking into account the pressure losses actually occurring in the system. Specific knowledge of the hydraulic resistances in the network is not required.
  • a system for regulating a pumping station in a hydraulic network with which a medium to be conveyed to at least one consumer can be pressurized, the pressure being adjustable as a function of the volume flow through the pumping station according to a control curve, the system for this purpose is set up to form the control curve from a plurality of partial pressure curves, and to define these partial pressure curves in each case for a volume flow interval of a number of seamlessly adjoining volume flow intervals corresponding to the plurality on the basis of pressure and volume flow values of the network that are determined and to be evaluated at intervals.
  • the control curve is made up of the plurality of partial pressure curves, each of which is defined for a specific volume flow interval.
  • the respective partial pressure curve of a specific volume flow interval is preferably defined or determined dynamically during operation, pressure and volume flow values being determined for this purpose and those values being evaluated which are assigned to the specific volume flow interval. In this way, a control curve is formed, which when used, the control of the pumping station is optimally adapted to the hydraulic network and the pumping station is operated particularly favorably in terms of energy.
  • FIG. 1 shows a building 10 with a drinking water supply that is fed with pressurized drinking water from a central supply line 9 of a municipal supplier.
  • the drinking water system comprises a pump station 1 set up inside the building 10 in the manner of a pressure booster system, which is connected on the input side via a feed line 16 to the central supply line 9, and on the output side is connected to a hydraulic network 8, 2, which has a large number of consumers 3 to which the drinking water is directed.
  • the consumers 3 are formed here by tapping points for drawing off the drinking water. For example, consumers, water fittings such as sinks, bathtubs or shower fittings, toilets, washing machines or dishwashers, etc. are formed.
  • the network 8, 2 comprises a pressure line 8 connected to the output of the pumping station 1, from which two local supply lines 2 branch off here, along which the consumers 3 are arranged. Viewed hydraulically, the consumers 3 thus all have a different distance from the pumping station 1, so that each line path from the pumping station 1 to one of the consumers 3 causes an individual pressure loss.
  • the pumping station 1 comprises two pumps 17 arranged in parallel, which can be operated alternatively or cumulatively.
  • a control and regulating unit 7 is provided for controlling and / or regulating the pumps 17 and adjusts their output and / or speed accordingly.
  • the pumping station can also have only one pump 17 or more than two pumps, for example three or four pumps 17, which can be hydraulically parallel and / or in series.
  • the control and regulation unit 7 can structurally be part of the pumping station 1, but alternatively it can also be located outside the pumping station, for example part of a central control and / or regulation of a building technology.
  • the hydraulic network can also have two or more pressure lines 8 and / or the pressure line 8 can supply three or more floors. In one embodiment variant, three or more local supply lines 2 can branch off from the pressure line 8.
  • a local supply line may be divided into two or more further lines.
  • the local supply lines 2 the same number of consumers 3 may be present, the local supply lines 2 have the same length, or the spacing between the consumers may be equidistant. So shows Figure 2 an exemplary drinking water system in which the local supply line 2 extending on the second floor is on the one hand shorter than the local supply line 2 extending on the first floor and on the other hand has fewer consumers 3 than the local supply line 2 extending on the first floor .
  • the pumping station 1 increases the pressure of the central supply line 9 and conveys the drinking water via the pressure line 8 and the local supply lines 2 to the consumers 3, provided that at least one of the extraction points 3 opens.
  • the pumping station 1 is regulated in such a way that a certain outlet pressure is present at its outlet, which ensures that there is sufficient flow pressure even at the worst extraction point 3.
  • the pressure losses that exist between the pumping station 1 and the respective extraction point 3 must be taken into account here.
  • the worst extraction point 3, also called the bad point, is generally that extraction point which, viewed geographically, is located at the highest and / or is the furthest away from the pumping station 1. From a hydraulic point of view, it is that extraction point 3 which the water experiences the greatest hydraulic resistance to reach.
  • the pressure of the pumping station 1 at the outlet is set to a constant value according to the prior art, that is to say regulated according to a constant pressure control curve.
  • the pressure p out at the outlet of the pumping station is constant over the volume flow Q.
  • the method according to the invention is based on this mode of operation and adapts the control curve in such a way that the output pressure depends on the volume flow Q is set by the pumping station 1 according to a new control curve.
  • This new control curve is made up of a plurality of partial pressure curves p soll, 1 (Q). ..., p, is to (Q) n formed, respectively, ..., n .DELTA.Q a flow interval .DELTA.Q 1 of a plurality of corresponding number n gaps of adjacent flow .DELTA.Q intervals 1, ..., n on the basis .DELTA.Q determined and pressure and volume flow values of the network to be evaluated at intervals can be defined.
  • the pressure and volume flow values can be at least system pressure values p sys (t v ), p sys, k (t v ) of the system pressure p sys, p sys, k present at a system point 5, 5a, 5b as well as volume flow values Q ( t v ) of the flowing or conveyed volume flow Q at different times t v .
  • the worst point ie the location of the worst extraction point 3 can be selected as system point 5.
  • This has the advantage that the maximum pipe losses that occur are taken into account for the formation of the control curve, thus ensuring that even the worst extraction point 3 is supplied with sufficient operating pressure if the pumping station 1 is regulated according to the partial pressure curves according to the invention.
  • the system pressure p sys of this worst extraction point 3 is therefore preferably determined.
  • this is a withdrawal point 3, which is located at the end of one of the local supply lines 2, in particular that withdrawal point which is the highest.
  • the system point 5 or the first or second system point 5a, 5b can also be located before or after an extraction point 3, in particular before or after the bad point.
  • the resulting inaccuracy in the value acquisition is slight and therefore does not impair the method according to the invention.
  • the system point 5 is preferably located in the immediate vicinity of the extraction point 3, since the installation of a measuring device is easiest there.
  • the system pressure values are preferably determined by measuring by means of a measuring device such as a pressure sensor.
  • the system pressure p sys , p sys, k can alternatively be calculated or estimated from other variables.
  • the volume flow Q is determined. This can also be done by measuring by means of a measuring device such as a volume flow sensor 6, but alternatively also computationally from other variables such as the power or the speed of one of the or both pumps 17.
  • the measuring device 6 can be arranged at the entrance of the pumping station 1, for example.
  • the volume flow can be estimated, for example on the basis of mathematical, electro-mechanical and / or mechanical-hydraulic models of the pumping station 1.
  • one or more measuring devices are present, they preferably form part of the system according to the invention for regulating the pumping station 1.
  • the measuring device for the outlet pressure and / or for the volume flow can be structurally combined with the pumping station 1.
  • the existing measuring devices can be connected to the control and regulation unit 7, for example via a cable connection and / or via a radio connection.
  • a cable connection has the advantage of reliable and essentially simultaneous detection of the system pressure or one of the system pressures, the outlet pressure and / or the volume flow.
  • a radio link has the advantage of easy installation or retrofitting of components to be connected in terms of data technology, such as a measuring device for recording the system pressure, since there is no need to lay a data line.
  • the system pressure p sys , or the respective system pressure p sys, k , and the volume flow Q are suitably assigned to one another over time, ie preferably determined at the same or essentially the same point in time t v . Because of this common time reference, they form a unit in the form of a data tuple. For the definition of the control curve, a large number of data tuples is preferably determined at different times.
  • the determination of the pressure and volume flow values in particular the acquisition of the data tuples, can take place at time intervals, for example either at certain times, such as on the hour, or always after a period of time, e.g. every 15 minutes. They can therefore be determined periodically. Alternatively or cumulatively, certain events can trigger the determination of pressure and volume flow values, for example the opening of an extraction point.
  • the pressure p sys , p sys, k at the system point 5, 5a, 5b is identical or at least almost identical to the output pressure p from the pumping station 1 when no extraction point is open or no consumer 3 consumes anything .
  • the volume flow Q is also zero and the corresponding data tuple cannot be used.
  • these cases can nevertheless initially be recorded as pressure and volume flow values, with filtering of the data tuples then being able to follow, in which such data tuples with volume flow zero and / or those with a system pressure value essentially the output pressure p from the pumping station 1 removed.
  • a system pressure value essentially the output pressure p from the pumping station 1 removed.
  • transition effects are, for example, a settling, ie decaying periodic pressure fluctuations.
  • it can be determined during operation of the pumping station 1 when the change over time of a volume flow Q other than zero is essentially constant for at least a certain period of time, only in this case the pressure value or values p sys (t v ), p sys, k (t v ) and the volume flow value Q (t v ) are recorded. Because in this case the transition effects have largely subsided.
  • the determination of the pressure and volume flow values takes place at least at the beginning of the method and at least for a certain period of time, since they form the basis for the definition of the partial pressure curves.
  • the longer the period the more values or data tuples are collected and the more precisely the control curve can be adapted in sections to the actual conditions. It is not necessary to limit the data collection to this period. Rather, the method according to the invention can be used continuously during the operation of the pumping station 1, and in this way the control curve can be dynamically adapted again and again.
  • the end of the period can be determined by the beginning of the subsequent evaluation of the collected data tuples. A new period within which the data is recorded can then follow the ended period.
  • the determined pressure and volume flow values or data tuples can be evaluated as described below.
  • the data tuples can first be assigned to a volume flow data interval ⁇ Qd i , which correlates with one of the volume flow intervals ⁇ Q i , on the basis of their respective volume flow value Q (t v).
  • the collected data are thus combined into a group with regard to the partial pressure curves to be defined, the groups also being sorted.
  • the time reference of the pressure and volume flow values or the data tuples is then no longer important.
  • the pressure loss ⁇ p from the pumping station 1 to the corresponding system point 5, 5a, 5b is then calculated for each data tuple.
  • this can take place in that the difference is formed from an output pressure setpoint p booster of the pumping station 1 and the system pressure value p sys (t v ), p sys, k (t v ) of the respective data tuple.
  • the output pressure setpoint p booster of the pumping station 1 is known since it corresponds to the constant pressure to which the pumping station 1 is regulated at least at the beginning of the method according to the invention. It defines the initial constant pressure control curve according to which the output pressure p out is set by the control and regulation unit 7.
  • the output pressure p from the pumping station 1 does not, or at least not always, correspond to the output pressure setpoint p booster in practice, because dynamic pressure changes occur upstream and / or downstream of the pumping station, which are regulated accordingly.
  • the pressure losses from the pumping station 1 to the corresponding system point 5, 5a, 5b can be calculated more precisely if the pressure p out actually present at the output of the pumping station 1 is used instead of the output pressure setpoint p booster.
  • the pressure and volume flow values determined or to be determined also include the output pressure p from the pumping station 1.
  • the outlet pressure p can also be determined or estimated from measurement technology or computation, for example on the basis of a mathematical model of the pumping station 1 a pressure sensor which is suitably arranged at the exit of the pumping station 1.
  • each data tuple then comprises three elements and thus forms a data triple.
  • the pressure loss ⁇ p (t v ) can be calculated from the system pressure value p sys (t v ), p sys, k (t v ) and the determined output pressure value p from (t v ) of each data tuple can be determined by forming the difference.
  • a pressure loss ⁇ p (t v ) results from each data tuple.
  • FIG. 4 A diagrammatic representation of the determined data tuples is given in Figure 4 shown.
  • a pQ diagram it shows the output pressure value p from (t v ), the system pressure value p sys (t v ), p sys, k (t v ) - each formed by a small circle - for different data tuples formed at different times t v - and the existing volume flow value Q (t v ).
  • the data tuples of the four times t 1 , t 2 , t 3 , t 4 are particularly emphasized.
  • the vertical distance between the circles corresponds to the pressure loss ⁇ p (t v ) at the respective point in time (t v ).
  • the output pressure value is p from (t v) for all detected data tuples on an output pressure value p booster corresponding line, demonstrating that instead of the actual output pressure values p from (t v) of the output pressure setpoint p booster used without having to accept significant deviations and thus deterioration in the quality of the process.
  • This is in Figure 5 illustrated.
  • a differentiation was made with regard to their location, namely in that this location was referenced by the index k at the corresponding system pressure p sys, k, it ultimately the location of the acquisition does not matter. Because ultimately only the level of the pressure losses and their assignment to a volume flow data interval ⁇ Qd i are important . With two system locations 5a, 5b, only the amount of data tuples recorded in the same time span doubles.
  • a pressure loss can initially be calculated from the system pressure value p sys (t v ), p sys, k (t v ) and the output set point p booster of the pumping station 1 or the determined output pressure value p from (t v ) of each data tuple by forming the difference ⁇ p (t v ) can be determined from the output of the pumping station 1 to the system point 5, 5a, 5b, and then this determined pressure loss ⁇ p (t v ) can be assigned to a volume flow data interval ⁇ Qd i on the basis of the volume flow value Q (t v) of the respective data tuple. The time reference is then no longer important. Rather, the pressure loss ⁇ p can be specified as the j-th value of the i-th volume flow data interval ⁇ Qd i.
  • the intervals are thus each down through a minimum value or initial value and limited upwards by a maximum value (end value), whereby the maximum value of a volume flow interval ⁇ Q 1 corresponds to the minimum value of the next higher volume flow interval ⁇ Q i + 1 or where the minimum value of a volume flow interval ⁇ Q i corresponds to the maximum value of the next lower volume flow interval ⁇ Q i-1 .
  • the volume flow intervals ⁇ Q 1 , ..., ⁇ Q n therefore lie next to one another without any gaps. For a mathematically exact interval definition, these values may of course only be assigned to one of the intervals.
  • a partial pressure curve is established for each volume flow interval ⁇ Q 1 ,..., ⁇ Q n.
  • the number n of volume flow intervals ⁇ Q 1 , ..., ⁇ Q n or the corresponding number of partial pressure curves can in principle be freely selected.
  • at least 6 or 8 volume flow intervals ⁇ Q 1 , ..., ⁇ Q n should be used.
  • the method can also be carried out if only 4 volume flow intervals ⁇ Q 1 , ..., ⁇ Q n are used.
  • volume flow intervals ⁇ Q 1 ,..., ⁇ Q n are used.
  • the number n of volume flow intervals .DELTA.Q 1 ..., .DELTA.Q n are selected to be greater than when in the Figures 1 and 2 1 shown pump station.
  • 20 or 30 volume flow intervals ⁇ Q 1 ,..., ⁇ Q n can also be useful.
  • the volume flow intervals ⁇ Q 1 ,..., ⁇ Q n can already be established before the method according to the invention is carried out.
  • the volume flow intervals can have a width of 0.5 m 3 / h to 3 m 3 / h, in particular 1 m 3 / h.
  • the definition can also be made by defining the number n, in which case the volume flow range 0 ... Q max that can be conveyed by the pumping station 1 is or is divided into this number n volume flow intervals ⁇ Q 1 ..., ⁇ Q n.
  • the volume flow intervals ⁇ Q 1 ,..., ⁇ Q n then have essentially the same width, as a result of which the subdivision is simplified.
  • the volume flow intervals ⁇ Q 1 ,..., ⁇ Q n all have essentially the same width.
  • a division can be made every 1m 3 / h, with the last interval ending at Q max and being narrower than 1m 3 / h.
  • the interval width is then correspondingly smaller in the partial load range, so that a more precise adjustment to the actual pressure losses in the hydraulic network is possible here.
  • the limit values and thus the positions of the volume flow intervals ⁇ Q 1 ,..., ⁇ Q n can already be determined before the method according to the invention is carried out.
  • the volume flow .DELTA.Q intervals 1, ..., n can .DELTA.Q during the inventive process, ie dynamically during operation, are set in dependence of the determined pressure and flow values.
  • the definition can relate to the number n and / or the width of the volume flow intervals ⁇ Q 1 ,..., ⁇ Q n.
  • the recoverable from the pumping station 1 flow range 0 ... Q max may be a function of the determined pressure and flow values to the number n of volume flow .DELTA.Q intervals 1, ..., n .DELTA.Q be divided.
  • volume flow-related density of the data tuples ie on the basis of the number of pressure values occurring in a specific volume flow range.
  • narrower volume flow intervals ie more volume flow intervals
  • another volume flow area of the same width in which there are fewer data tuples In this way, a need-based fine adjustment of the control curve is carried out automatically. It is particularly easy to choose the width of the volume flow intervals ⁇ Q 1 ,..., ⁇ Q n such that they include the same or essentially the same number of data tuples.
  • the flow data intervals ⁇ Qd 1, ..., n are also ⁇ Qd completed portions of the volume flow range of 0 ... Q max that can be conveyed from the pump station. 1 With regard to their definition and width, what has been said above about the volume flow intervals ⁇ Q 1 ..., ⁇ Q n applies. They are thus also limited downwards by a minimum value and upwards by a maximum value.
  • the volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n form a type of data container for assigning the data tuples or the calculated pressure losses ⁇ p i, j to a volume flow range. Each volume flow data interval ⁇ Qd i correlates with a volume flow interval ⁇ Q i .
  • each volume flow data interval ⁇ Qd i is assigned to one of the volume flow intervals ⁇ Q i .
  • the volume flow intervals ⁇ Q 1 , ..., ⁇ Q n are congruent with the volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n . This is the case with the examples in the Figures 5 to 9 the case.
  • the volume flow intervals ⁇ Q 1 , ..., ⁇ Q n can also be offset from the volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n . This is for example in the example in Figure 11 the case that will be described below.
  • the partial pressure curves (the volume flow intervals ⁇ Q 1 , ..., ⁇ Q n ) are offset relative to the volume flow relative to the data containers (the volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n ), so that the definition of the pressure curves is not made for the same volume flow intervals for the assignment of the data tuples or the pressure losses takes place.
  • a representative value Dp rep be determined i, the one Pressure loss for the respective volume flow data interval or for the volume flow range covering the volume flow data interval.
  • the representative value ⁇ p rep, i can be, for example, the maximum value of the pressure losses ⁇ p i, j assigned to the corresponding volume flow data interval ⁇ Qd 1 ,..., ⁇ Qd n .
  • the greatest value is to be filtered out of the assigned pressure losses ⁇ p i, j.
  • the arithmetic mean or a quantile in the range from 75% to 95% of the total of the pressure losses ⁇ p i, j assigned to the corresponding volume flow data interval ⁇ Qd 1 ,..., ⁇ Qd n can be used as the representative value ⁇ p rep, i .
  • the quantile ensures that outliers in the calculated upward pressure losses are not taken into account when determining the representative value, so that excessively high pressures from the pumping station are avoided and thus energy is saved.
  • the formation of the arithmetic mean of the assigned pressure loss values of a volume flow interval leads to deviations upwards as well as downwards being compensated or averaged.
  • Figure 6 illustrates the result of determining a representative value ⁇ p rep, 1 , ⁇ p rep, 2 , ⁇ p rep, 3 , ... ⁇ p rep, n for each of the volume flow data interval ⁇ Qd 1 , ..., ⁇ Qd n , here from the amount of one respective volume flow data interval ⁇ Qd i associated pressure losses ⁇ p i, j the maximum is taken in each case.
  • These representative values ⁇ p rep, i thus indicate that there is no higher pressure loss for the corresponding volume flow interval or at least did not occur during the previous period in which the pressure and volume flow values were recorded.
  • a common default pressure value p set can then be added to all representative values ⁇ p rep, 1 ... ⁇ p rep, n .
  • This default pressure value p set can correspond to the pressure that one would like to have at least at an extraction point 3, also called comfort pressure in jargon. Since the representative values ⁇ p rep, i indicate the maximum pressure loss in the respective volume flow data interval ⁇ Qd 1 ,..., ⁇ Qd n , this comfort pressure is also achieved at all extraction points 3 for each volume flow. This addition gives an interval-related setpoint pressure for the pumping station 1, which must at least be achieved for the corresponding volume flow interval in order to ensure the comfort pressure.
  • This basic idea also includes a variant in which the determination of the representative values ⁇ p rep, i and the addition of the default pressure value p set are interchanged over time.
  • the common default pressure value p set can first be added to the pressure losses ⁇ p i, j and then the respective representative value ⁇ p rep, i can be determined.
  • the partial pressure curves p soll, 1 (Q),... P soll, n (Q) can be constant pressure curves.
  • each pressure curve p soll, i (Q) is defined by a constant setpoint pressure.
  • This variant is in Figure 7 illustrated. The p from the total of partial pressure curves will, 1 (Q), ... p soll, n (Q) control curve formed to p (Q) is then discontinuous. It has a jump at the interval limits, ie at the transition from one partial pressure curve to the next.
  • the constant setpoint pressure of the corresponding pressure curve p soll, i (Q) can be directly related to the representative value ⁇ p rep, i of that volume flow data interval ⁇ Qd i correspond, for which the corresponding partial pressure curve p should, i (Q) is at least partially defined.
  • the constant setpoint pressure of the corresponding pressure curve p soll, i (Q) can alternatively be the sum of the default pressure value p set and the representative value ⁇ p rep, i of that volume flow data interval ⁇ Qd i correspond for which the corresponding partial pressure curve p should, i is at least partially defined. It is precisely this second possibility that shows Figure 7 , in which the partial pressure curves p soll, 1 (Q), ... p soll, n (Q) are defined by the sum of the common default value p set and the corresponding representative value ⁇ p rep, i of the respective volume flow data interval ⁇ Qd i .
  • volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n in Figure 7 are congruent with the volume flow intervals ⁇ Q 1 , ..., ⁇ Q n , the definition of the partial pressure curves p soll, 1 (Q), ... p soll, n (Q) takes place here not only partially for a respective volume flow data interval ⁇ Qd i but Completely. If the volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n were shifted to the volume flow intervals ⁇ Q 1 , ..., ⁇ Q n , this would not be as it is in Figure 11 the case is.
  • the partial pressure curves p soll, 1 (Q),... P soll, n (Q) can be proportional pressure curves.
  • each partial pressure curve p soll, i (Q) is defined by a setpoint pressure p soll (Q) that increases linearly with the volume flow Q.

  • Figure 8 shows that the representative value ⁇ p rep, i determined and established for a volume flow data interval ⁇ Qd i only defines the setpoint pressure at the beginning of the partial pressure curve p soll, i (Q) determined for this volume flow data interval ⁇ Qd i compared to a partial constant pressure curve.

  • one of the flow rate data intervals ⁇ Qd i no data tuples or no pressure drop Ap (t v), .DELTA.p k (t v) is assigned, as a representative value Dp rep, i for this flow data interval ⁇ Qd the representative value i Ap rep, i -1 , ⁇ p rep, i + 1 of the preceding or following volume flow data interval ⁇ Qd i-1 ⁇ Qd i + 1 can be used. This ensures that the control curve can be defined for the entire volume flow range of the pumping station 1.
  • Figure 10 illustrates an embodiment variant in which the representative values ⁇ p rep, 1 , ... ⁇ p rep, n are not assigned to the beginning of the volume flow data intervals ⁇ Qd 1 , ..., ⁇ Qd n , but approximately to the middle.
  • the volume flow .DELTA.Q intervals 1, ..., n .DELTA.Q have therefore being the same width as the flow data intervals ⁇ Qd 1, ..., n ⁇ Qd they are offset to these by half the width.
  • Figure 11 shows the course of the final partial pressure curves p soll, 1 (Q), ... p soll, n (Q).
  • the first volume flow interval ⁇ Q 1 is only half the width of the remaining volume flow intervals ⁇ Q 2 ,..., ⁇ Q n . This shows that not all volume flow intervals ⁇ Q 1 , ..., ⁇ Q n have to have the same width.
  • a partial constant pressure curve is defined for the first volume flow interval ⁇ Q 1 , the setpoint value of which is defined by the representative value ⁇ p rep, 1 assigned to the first volume flow interval ⁇ Q 1 .
  • partial proportional pressure curves are defined for the remaining volume flow intervals ⁇ Q 2 , ..., ⁇ Q n. This shows that not all partial pressure curves have to be of the same order.
  • the maximum pump curve M limits the operating range of the pumping station 1. No operating points beyond this pump curve M can therefore be reached.
  • the pump curve M thus superimposes the control curve p soll (Q) in the or in the last volume flow interval (s) in such a way that operating points on the partial pressure curve p soll, n (Q), formed for the last or possibly penultimate volume flow interval ⁇ Q n , n (Q), the beyond the maximum pump curve M would lie on the maximum pump curve M.
  • FIGS 3a and 3b now show a graphic representation of a first and second process sequence according to the invention in its basic steps.
  • a first step 11 in both variants, data tuples are determined from pressure and volume flow values.
  • step 12a the assignment of the data tuples to a volume flow data interval follows, which in step 13a is followed by the calculation of a pressure loss for each data tuple.
  • steps 14, 15, 16 are again the same for both variants.
  • a representative value is determined for each volume flow data interval, step 14.From each representative value, a partial pressure curve is then defined for each volume flow interval correlated with the corresponding volume flow data interval, step 15, which is then used to control the pumping station along the lines of the totality of the Subsequent control curve formed partial pressure curves, step 16. The process is then repeated. After step 16, it is continued with step 11 and thus the defined Dynamic control curve, especially adapted again and again.
  • the formation of the partial pressure curves can be described as above.
  • the partial pressure curves can be constant pressure curves, or proportional pressure curves, or partly constant pressure curves and partly proportional pressure curves.
  • the method according to the invention can be carried out as part of a commissioning procedure immediately after the installation of the pumping station 1. If the method is started, one of the extraction points 3 and / or two or more, in particular all extraction points 3, need only be opened one after the other. At least the downside should be among them. This has the advantage that pressure and volume flow values can be recorded in a short time for the entire conveyable volume flow range of the pumping station 1. Then the data acquisition, step 11, can be ended and the evaluation, steps 12 to 15, can be started.
  • the method according to the invention can take place independently of the installation of the pumping station 1 as part of its intended operation. This requires a longer period of time until a sufficient number of pressure and volume flow values are recorded. However, there is no commissioning procedure for data acquisition.
  • the pumping station can initially be regulated according to a pressure curve that is constant over the entire volume flow.
