摘要： A method of automatically detecting a rolling-element bearing fault in a rotating machine is provided. The method includes receiving, from at least one sensor, a sensor signal that includes at least one frequency, converting the sensor signal to a digital vibration signal, modifying the vibration signal to generate an envelope signal, and applying a transform to the enveloped signal to generate an envelope spectrum. The method uses certain relationships among envelope spectral line amplitudes and their harmonics to detect bearing faults. As such, the method detects a bearing fault without reference to predefined fault frequencies. Systems for implementing the method are also provided.

摘要： Disclosed is a method for assessing deterioration in a gearbox. Data is obtained from an operating gearbox regarding harmonic frequencies and their related sidebands generated as a consequence of the gearbox operation. In a first embodiment, a Sideband Energy Ratio (SER) is calculated by dividing the amplitude of the sum of sideband signals associated with a harmonic to the amplitude of the harmonic. In a second embodiment, a SER is calculated based on sideband amplitudes associated with adjacent harmonics. The ratio may be monitored over time or compared to one or more values to provide an indication of deterioration.

摘要： Systems and methods are provided for monitoring operating machinery, acquiring data regarding characteristic behavior of the machinery being monitored, and processing of the data to determine and indicate when significant deviations from normal operating conditions are occurring that represent maintenance initiating or failure mode events. The method includes learning what normal operating conditions are for a machine of interest by acquiring data during observed normal operation, then calculating detection threshold values based on the acquired data. Finally, real-time monitoring of the machinery of interest during operation is employed, with alarms triggered upon occurrence of a previously-defined number of occurrences of behavior exceeding parameters associated with normal operation behavior.

摘要： A method estimates closure of a suction valve. A number of samples are received, each including a reference and a pressure reading. Data points are determined from the samples, each including a reference and a pressure indicator. The reference indicator directly correlates to the reference reading, and the pressure indicator correlates to an average of pressure readings collected about the sample. The data points include a suction data point, a discharge data point, and an index data point. A best-fit linear equation representing data points from about the index data point to about the discharge data point is determined. A half-slope linear equation is also determined, which has half the slope of the best-fit linear equation and the index data point as one solution. A best-fit polynomial equation representing data points from about the suction data point to about the index data point is determined, and a target reference indicator associated with a maximum directed distance from the best-fit polynomial equation to the half-slope linear equation is identified. The suction valve is estimated to close at a point identified by the target reference indicator.
