Patent number: 8676387Abstract: 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.Type: GrantFiled: October 13, 2008Date of Patent: March 18, 2014Assignee: General Electric CompanyInventors: Olga Malakhova, John Wesley Grant

Patent number: 8147211Abstract: 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.Type: GrantFiled: January 3, 2006Date of Patent: April 3, 2012Assignee: General Electric CompanyInventors: John W.

Patent number: 7855545Abstract: A sinusoidal modulated signal and noise are applied to a system consisting of two oscillators of the so-called General Type, which can be, but are not limited to, the Van der Pol type, Rotator type, Tracking Force type, Linear type, or any other type of oscillator. The two oscillators in the system can also be of different types. The General Type oscillators are tuned for specific frequencies of the incoming sinusoidal modulated signal. The process of adjusting of oscillators to an incoming signal is known as Dynamic Synchronization. During the transitional period, because the noise is random, the noise pushes the frequencies of the General Type oscillators in opposite directions over time and thus self-eliminates its impact on such oscillators. The resulting signal is much less noisy, i.e., clarified, so that the sinusoidal modulated signal can be further evaluated by, for example, extracting and further analyzing its spectral peaks.Type: GrantFiled: January 17, 2007Date of Patent: December 21, 2010Assignee: General Electric CompanyInventors: Alexei Petchenev, John W.
