    摘要: A method for predicting failures in an industrial system (100), the method comprising the steps of a) providing an input time series (1) comprising a plurality of data points (t1, .., n, y1, ..., n), each data point containing a time stamp (ti) and a value (yi) of a variable W measured at the respective time stamp (ti); b) calculating fitting parameters (2) of a log-periodic power law model function W(t) (3) that give the smallest mean squared error mse (4) to the input time series (1) or to at least one subset (1a) of data points of said input time series (1), to obtain a fitted function (5); c) identifying the local maxima (Nmax) and the local minima (Nmin) of the fitted function (5); d) determining a trend (Tmax) from at least some of the identified local maxima (Nmax) and a trend (Tmin) from at least some of the identified local minima (Nmin), respectively; e) identifying whether or not a given data point (tn, yn) of the input time series (1) is a critical point (tc), wherein said given data point (tn, yn) is a critical point (tc) if both trends (Tmax; Tmin) have the same character for the last point (tn-1, yn-1) of the input time series preceding said given data point (tn, yn); and, if a critical point (tc) has been identified in step e), a step f) outputting a signal (7) indicating that a failure of at least one component (8) in the industrial system (100) was predicted.

    摘要: The poppet valve (1) for a piston compressor comprises a catcher (3), a valve body (2) with a plurality of inlet ducts (2a), wherein each inlet duct (2a) opens into a valve seat (7a), and comprises a plurality of closing elements (4) which can be moved in an axial direction (A), wherein each inlet duct (2a) is assigned a closing element (4), and wherein the valve seat (7a) is arranged so as to lie opposite the associated closing element (4) in the axial direction (A) in such a way that the valve seat (7a) can be closed by way of the closing element (4), wherein a spring (5) is arranged between the catcher (3) and the closing element (4), in order to bring about a prestressing force on the closing element (4), which prestressing force is oriented towards the valve seat (7a), wherein the spring (5) encloses an inner space (5c), and wherein a guide part (6) which runs in the axial direction (A) is arranged on the catcher (3), on which guide part (6) the closing element (4) is mounted such that it can move, in particular slide, in the axial direction (A), wherein the spring (5) encloses the guide part (6) and the closing element (4) in the axial direction (A) along a part section (4e) from the outside, with the result that both the guide part (6) and the closing element (4) are arranged along said part section (4e) within the inner space (5c) of the spring (5).

    摘要: The piston ring (1) for a reciprocating compressor comprises: a one-part sealing ring (2) that extends in a peripheral direction (N) about a center (M) with an axial direction (H) and has an arcuate outer surface (2k), the sealing ring (2) having a butt joint with joint ends (21) and a gap (2a) that extends between the joint ends (21) in the peripheral direction (N); and a joint seal (3) for sealing the gap (2a), said joint seal (3) being symmetrical with respect to a plane of symmetry (S). The joint seal (3), starting from the plane of symmetry (S), comprises two limbs (3d) that extend at both sides in the peripheral direction (N), the two limbs (3d) extending over a total angular range of 20° to 180° and having a radially outwardly directed, arcuate limb outer face (3g). The joint seal (3), starting from the plane of symmetry (S), comprises a contact part (3b) that extends at both sides in the peripheral direction (N) and projects beyond the limbs (3d) in the axial direction (H), said contact part (3b) extending only across a partial angle of the two limbs (3d) in the peripheral direction (N). The contact part (3b) has a radially outwardly directed contact surface (3c) which is set back with respect to the limb outer face (3g) in the radial direction such that the limbs (3d) form a stop (3h) along the contact surface (3c), which stop is aligned in the axial direction (H). The sealing ring (2) and the joint seal (3) are adapted to each other such that, when assembled, the joint seal (3) rests laterally against the sealing ring (2) via the stop (3h) and that the contact surface (3c) of the contact part (3b) runs along the gap (2a) and covers same in the peripheral direction (N).

    摘要: The oil scraper ring (1) has a retaining ring (2) and a scraper (3) with a scraper disk (3a). The scraper is arranged in the retaining ring such that the scraper disk is aligned against the center of the oil scraper ring for scraping off the oil in a piston rod (6). The scraper consists of multiple scraper segments (3e), which are arranged in a peripheral direction of the oil scraper ring. An independent claim is also included for an oil scraper ring package with a locking device.
