Abstract: A computer-implemented method for determining an operational property of a drill-rod borehole pump. A load-distance diagram with curve points for the pump is ascertained by an analysis device and provided as an operational load-distance diagram with operational curve points. In a training mode, a model load-distance diagram with respective model curve points is provided, and normalized to a specified reference variable, and for at least one sub-quantity of the model curve points, a model is generated and trained on the basis of a Kohonen network with elliptical Fourier descriptors. In an operating mode, the operational curve points are normalized to the reference variable, elliptical Fourier descriptors are determined for the operational curve points, and checked to determine a similarity between the elliptical Fourier descriptors of the operational curve points and the model of the Kohonen network, and if so, the operational property of the pump is determined.

Abstract: A computer-implemented method for determining an operational property of a drill-rod borehole pump. A load-distance diagram with curve points for the pump is ascertained by an analysis device using a detection device and is provided as an operational load-distance diagram with operational curve points. Wherein in a training mode, a load-distance diagram model for the pump with model curve points is generated and trained on the basis of machine learning, at least two specified analysis regions are determined in the load-distance diagram model, and a reference point is ascertained from the model curve points of at least one region. In an operating mode for the operational load-distance diagram, a check is carried out to determine whether the at least one reference point is contained within the surface contained by the operational curve points, and if so, the operational property of the conveyor pump is determined therefrom.

Abstract: Among other things, a machine-based method is described. The method comprises recording object classes of an object model, producing an object representation for data of two or more data sources based on a mapping of data formats of the data sources to the object classes of the object model, and producing mapped data from the data sources. The mapped data is available in objects of the object classes and is comparable in the object representation. At least two of the data sources have different data formats.

Abstract: In a cast engine block for liquid-cooled internal combustion engines with V-shaped cylinder arrangement, the cylinders are arranged in cooling medium spaces delimited by cylinder blocks. A spiral housing 10 of a cooling medium pump 11 having a radial rotor is partially integrated into one of the end walls of the engine block within the area of a cylinder block. A gear box adapted to be fastened at the end wall includes a closure wall corresponding to the end walls surface as well as side walls for the sealing abutment of a separate cover. The other part of the spiral housing inclusive a pressure connection is integrated into the closure wall. This spiral housing includes a collar for the plug-in arrangement of the cooling medium pump. The side wall of the gear box is arranged about the collar receiving the cooling medium pump for an arrangement of the cover separate at the gear box from the cooling medium pump.
