摘要： A method for monitoring a condition of at least one valve positioned with respect to at least one of a first chamber and a second chamber of a reciprocating compressor is provided. The method includes establishing a compressor operation cycle including a valve opening event, a valve closing event and/or a rod reversal event. A crank angle is determined at each of the valve opening event, the valve closing event and/or the rod reversal event during the compressor operation cycle using at least one of a static pressure input and a machine speed input. The method further include diagnosing a valve leak condition during the compressor operation cycle at the valve closing event, wherein the at least one valve is closed.

摘要： A method of detecting a signal (S) of interest contained within a waveform (F) comprised of a plurality of signals within a frequency spectrum, as well as random noise. After first detecting the waveform, a determination is made as to whether the duration (Td) of the waveform is sufficient for subsequent processing. If the duration is not sufficient, the waveform is concatenated with itself to produce a waveform of sufficient duration. The concatenated waveform is then processed and the results supplied as an input to an oscillator (24) operating at a nominal output frequency. The oscillator cancels the effects of noise in the waveform and the frequency of the oscillator shifts to a different frequency which is a function of the signal of interest. The shift in output frequency of the oscillator is detected and analyzed to obtain the signal of interest. The oscillator can be either a general purpose oscillator or a Van der Pol oscillator.

摘要： Embodiments of methods and systems for monitoring of pumps are provided. According to one embodiment of the invention, there is disclosed a method for determining operating states of pumps. The method may include receiving, by a controller from a first sensor communicating with a first pump, a first vibration measurement. Further, the method may include receiving, by the controller from a second sensor communicating with a second pump, a second vibration measurement. Operating states of the first pump and the second pump may be thus determined based at least in part on comparing the first vibration measurement to a first operating condition and comparing the second vibration measurement to a second operating condition. A control action may be transmitted responsive to determining the respective operating states of the first pump and the second pump.
