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 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.
F04D 7/04 - Pompes adaptées à la manipulation de liquides particuliers, p. ex. par choix de matériaux spéciaux pour les pompes ou pièces de pompe du type centrifuge les fluides étant visqueux ou non homogènes
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.

The invention relates to a method for controlling at least one first circulation pump (17b, 17c) of a heating or cooling system (1) having a primary circuit (2, 2a) and a secondary circuit (4, 30a) coupled therewith at a transfer point (3, 29). The first circulation pump (17, 17b, 17c, 17b’) conveys a heating or cooling medium in the primary circuit (2, 2a), and in the second secondary circuit (4, 30a), at least one second circulation pump (12, 17d) is located that conveys a heating or cooling medium in at least one partial area of the secondary circuit (4, 30a). The volume flow rate (formula I) of the first circulation pump (17, 17b, 17c, 17b') is controlled in functional dependence on the volume flow rate (formula II) of the secondary circuit (4, 30) behind the transfer point (3, 29). In this way, a demand-based, and thus an energy-efficient control of the primary-side circulation pump is achieved. The invention further relates to a pump system, comprising the at least one first and the at least one second circulation pump for carrying out the method.

ADAPTATION OF THE DELIVERY HEAD OF A CENTRIFUGAL PUMP TO A CHANGING VOLUMETRIC FLOW RATE
The invention relates to a method for operating an electric-motor-driven centrifugal pump (3) in a hydraulic system (4) having at least one self-controlled load, wherein a gradient (dQakt/dt) of the volumetric flow rate (Qakt) of the centrifugal pump (3) is determined and the current setpoint delivery head (H_soll) of the centrifugal pump (3) is calculated from a mathematical operation on the gradient (dQakt/dt) weighted with a gain factor (K) and the last specified setpoint delivery head (Hsoll,alt). The operation describes a positive feeback between the setpoint delivery head (Hsoll) and the volumetric flow rate (Qakt). The gain factor (K) is determined from a calculation instruction, which is modified dynamically during the operation of the centrifugal pump (3) with consideration of the current operating point of the centrifugal pump (3) and with consideration of a current and/or at least one past state of the hydraulic system (4).
The invention relates to a method for producing a short-circuit inner rotor (1) for an electric motor, comprising a laminated rotor core (2) with rotor grooves (6) which are filled with copper (10) or a copper alloy for forming short-circuit bars (8) of a cage. The rotor grooves (6) of the laminated rotor core (2) are initially closed towards the outer casing (5) and are filled with the copper (10) or copper alloy in a centrifugal casting process, wherein short-circuit rings (9) are simultaneously formed at the axial ends of the rotor grooves (6).
b) of the outer part (2) extend angularly over less than an entire helix along the axial length (L) of the part, so that during operation pumping chambers that are open to both ends are created, through which sudden pressure relief takes place.

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.
The invention relates to a method for the configuration of a first electromotive pump assembly (1b) using configuration data. In this case, configuration data and/or operating data of a second pump assembly (1a) are stored in a non-volatile memory unit (6, 6a) of pump electronics (3a) of the second pump assembly (1a) and are transmitted from the second pump assembly (1a) to the first pump assembly (1b). Said first pump assembly then transfers said data into the pump electronics (3b) thereof. The transmission may be performed by way of a memory module, by radio or optically by means of a code. The invention also relates to pump assemblies (1a, 1b) which are correspondingly designed to be used in the method according to the invention.

DISINFECTION IN A CENTRIFUGAL PUMP OR IN A PUMP SYSTEM HAVING AT LEAST ONE CENTRIFUGAL PUMP
The invention relates to a method for thermal disinfection in a centrifugal pump, or in a pump system having at least one centrifugal pump, conveying drinking water, service water, waste water, or other liquid media. Said centrifugal pump or pump system has a suction port terminating at the suction side of the centrifugal pump or the pump system, and has a pressure port terminating at the pressure side. When the suction port and/or the pressure port is/are closed, the centrifugal pump or the pump system conveys the medium in a cycle via a connection that is located inside the centrifugal pump or the pump system and that hydraulically short-circuits the pressure side with the suction side intermittently such that the medium, and thus the parts of the centrifugal pump or the pump system touching the medium, are heated to a disinfecting temperature.
