A torque required to achieve the modulated reference speed or adjustment of a modulated torque and the actual speed of the centrifugal pump is determined. Then a model speed is calculated with the aid of a mathematical pump-motor model simulating the behavior of the centrifugal pump within a hydraulic system as well as a disturbance signal from a deviation of the model speed from the actual speed of the centrifugal pump. Then a correction signal is determined by integrating the product of the disturbance signal and a sine or cosine signal with a multiple of the excitation frequency over at least one period of the excitation signal. Finally, at least one model parameter of the pump-motor model is determined as a function of the correction signal and the flow rate and/or the head is calculated using the adapted pump-motor model.
The invention relates to a process for obtaining drinking water (3) from untreated water (2) by ultrafiltration and reverse osmosis, wherein the drinking water (3) has a desired target value for a water parameter relating to its composition and is provided in a fresh water tank (15). The invention further relates to a drinking water treatment system for performing the process. In order to achieve the target value, a first water volume is created by obtaining a filtrate from the untreated water (2) via ultrafiltration and obtaining a permeate therefrom by reverse osmosis, the volume of said permeate constituting the first water volume, and a second water volume is created by obtaining a filtrate from the untreated water (2) by ultrafiltration, the volume of said filtrate constituting the second water volume, where the first and second water volumes are then mixed to obtain the drinking water (3), and the first and second water volumes are such that the mixture thereof has the desired target value.
The invention relates to a method for controlling a backflushing operation of an ultrafiltration module (1) of a drinking water production plant having a raw water side (8), a filtrate side (9) and an ultrafiltration membrane (10) which separates the raw water side (8) from the filtrate side (9) to filter raw water (2) on transition from the raw water side (8) to the filtrate side (9). In backflushing operation, backflushing water, in particular filtrate (3), is pumped from the filtrate side (9) to the raw water side (8) and exits there as retentate (4) in order to remove solid particles accumulated on the ultrafiltration membrane (10) on the raw water side (8). According to the invention, the turbidity of the retentate (4) is measured by sensors continuously or at intervals, and the backflushing operation is ended when the turbidity falls below a predefined limit valve (s) between 0.02 NTU and 0.1 NTU. This reduces the amount of water needed during backflushing operation.

A plug-in electronic expansion module for pump electronics of a centrifugal pump for expanding the pump electronics with at least one additional function has a housing having a lower face and connecting formations thereon for attachment to a pump housing of the pump electronics. Electronics in the module housing provide the additional function. A base is provided on the lower face, and an electrical interface connected to the pump electronics includes a flat support projecting tongue-like from the base on the lower face of the module housing through an opening in the pump housing and carrying contact-forming electrical traces.
A terminal box for a centrifugal pump is releasably connectable to an electronic extension module by a locking element. A pluggable electric interface extends through an opening from an underside of the base plate into the terminal box to electrically connect the pump control for establishing a data link. The locking element is slidable in the cavity and is movable manually from a first position to a second position and by a tool from this second position to this first position. It also has on a first side a resilient latch engaging with either a first recess of the terminal box and holding the locking element in the first position, or a second recess of the terminal box holding the locking element in the second position. Thus the locking element frees the module for plugging-in in the first position, and arrests the module in the second position.

The invention relates to an asymmetric pump impeller (1) for a pump unit for conveying a liquid which in particular contains solids, said impeller being formed at least to some extent in layers by an additive production method and having at least one cavity (5, 6) in the interior of the material of the impeller, said cavity being formed during the production in layers and closed completely towards the outside or except for an opening (7, 8) for removal of unhardened material from the cavity (5, 6). The cavity (5, 6) is positioned and designed in such a way that an inertia axis of the pump impeller (1) is displaced with respect to the axis of rotation (15) of the pump impeller (1). This has the advantage that the impeller is already largely free of unbalances immediately after the production or manufacture of the impeller, such that no or only minor subsequent balancing is required.

The invention relates to a method for detecting an abnormal operating state of a rotational-speed-controllable pump unit (1) operated at a specifiable rotational speed (n 0). A periodic excitation signal (fA(t)) of a certain frequency (f) is applied to a manipulated variable (nsoll) of the pump unit (1) in such a way that a hydraulic variable (H, Δp) of the pump unit (1) is modulated. From a mechanical and/or electrical variable (Pel) of the pump unit (1) as a system response (X(t)) to the excitation signal (fA(t)), an evaluation signal (I(t0), I(t)) is then calculated and it is determined therefrom whether an abnormal operating state exists. The invention further relates to pump electronics for the open-loop and/or closed-loop control of the target rotational speed of a pump unit (1), which pump electronics are designed to carry out the method, and to a pump unit having such pump electronics.

CENTRIFGUAL PUMP UNIT AND METHOD FOR ADJUSTING THE OPERATION THEREOF
The invention relates to a method for adjusting the operation of an electronically closed-loop or open-loop controlled centrifugal pump unit in a hydraulic system, in particular when the unit is used for the first time. According to said method at least two default values (Hset, Qset) defining an operating point (Bset) and comprising a first default value (Hset) for a first physical quantity (H) and a second default value (Qset) for a second physical quantity (Q), are input directly and separately of each other. From these default values (Hset, Qset) an operating curve (2a, 2b, 2c, 2e) and/or an operating range limit (3a, 3b, 3c, 3d) is then determined and set for the open-loop or closed-loop control of the centrifugal pump unit. This widens the possible uses of the pump unit to a large number of different applications. If the rated point of the hydraulic system is chosen as the operating point, the pump electronics system can set a closed-loop control curve that passes exactly through said rated point, such that the pump unit can be optimally adapted to the hydraulic system.
akt). The gain factor (K) is determined from a calculation instruction that is modified dynamically during operation of the centrifugal pump (3) taking into consideration the current operating point of the centrifugal pump (3) and taking into consideration a current and/or at least one past state of the hydraulic system (4).
The invention relates to a method of operating a pressurized wastewater-drainage system (1) having interconnected line sections (SA1 . . . SA9) for conducting wastewater to a transfer station (10) and a plurality of pump stations (2) connected to the line sections (SA1 . . . SA9) for collecting the wastewater, wherein at least a portion of the pump stations (2) transmits at least status information indicating its respective pump standby status to a central controller (3), wherein a group is formed from the set of pump stations (2) that are in pump standby in relation to one of the line sections (SA1 . . . SA9) such that the number of pump stations (2) of the group corresponds at least to a minimum number (p_min) of pump stations (2) associated with this line section (SA1 . . . SA9), and the pump station (2) or pump stations (2) of the group are then activated simultaneously by the central controller (3). A minimum flow rate is thus present in wide portions of the pressurized drainage system and for a maximum time, which results in a cleaning effect and thus reduces the danger of clogging.

METHOD FOR DETERMINING THE HYDRAULIC OPERATING POINT OF A PUMP ASSEMBLY
The invention relates to a method for determining a first hydraulic variable (Q) of a pump assembly (1), which is operated at a predefinable rotation speed (n o), from a mechanical or electrical variable (M act , P el , n act ) by evaluating a combination of the hydraulic variable (Q) with the mechanical or electrical variable (M act , P el , n act ). In this case, an actuating variable (Mtarget, ntarget) of the pump assembly (1) is acted on by a periodic excitation signal (fA, n(t), fA, H(t)) of a specific frequency (f) in such a way that a second hydraulic variable (H, Δp) is modulated. The current value of the first hydraulic variable (Q) is then determined from the mechanical or electrical variable (M act (t),Pel(t) nact(t)) as a system response (X(t)) to the excitation signal (fA, n(t), fA, H(t)) using the combination. The invention further relates to a pump electronics system and to a pump assembly which are designed to carry out the method.

CENTRIFUGAL PUMP WITH ULTRASOUND FLOW-THROUGH MEASUREMENT DEVICE
The invention relates to a centrifugal pump (1) for conveying a liquid, comprising an impeller (21) which is arranged in a pump chamber (20), and one suction nozzle (16) and one pressure nozzle (17) which are both attached to the pump chamber (20). The centrifugal pump comprises an ultrasound-based flow-through measurement device (2, 3, 18) which has at least two ultrasound units (2, 3) for emitting and/or detecting ultrasound pulses and which are internally located in or on the suction nozzle (16), pressure nozzle (17) and/or the pump chamber (20). At least one measurement line (6) is formed between the ultrasound units (2, 3), along which measurement line at least one first ultrasound pulse, which can be emitted upstream by one of the ultrasound units (2), can be detected by another of the ultrasound units (3) and at least one second ultrasound pulse, which can be emitted downstream by one of the ultrasound units (3), can be detected by another of the ultrasound units (2). The flow-through measurement unit (2, 3, 18) also has a sensor electronics unit (18) for measuring a runtime difference between the first and the second ultrasound pulses and for determining a flow-through of the centrifugal pump (1) on the basis of the runtime difference.
