Abstract: A method, system, and apparatus to monitor health of a compressor are provided. The method, system, and apparatus include detecting whether the compressor has a fault associated using one or more of performance-based modeling and structure-based modeling of physical aspects associated with operation of the compressor; diagnosing any detected fault to determine the cause or causes of the fault; and evaluating each diagnosed fault to assess the significance of the fault. Data pertaining to the cause or causes of the fault and the significance of the fault is used to output health information corresponding to a health state or status of the compressor. The method, system, and apparatus also predict future health-related conditions of the compressor, and data pertaining to the predicted future health-related conditions is used to output health information corresponding to a future health state or status of the compressor.

Abstract: A monitoring system for a fluid pump having a fluid end and a power end is provided. The monitoring system includes an inlet pressure sensor attached to an inlet manifold of the fluid end. The inlet pressure sensor generates a signal indicative of an inlet pressure of a fluid being supplied to the fluid end. The monitoring system includes a discharge pressure sensor attached to the fluid end. The discharge pressure sensor generates a signal indicative of a discharge pressure of the fluid exiting the fluid end. The monitoring system includes at least one accelerometer attached to the fluid end. The accelerometer generates a signal indicative of vibrational data of the fluid pump. The monitoring system includes a controller which receives signals from the inlet pressure sensor, the discharge pressure sensor and the accelerometer and determines a possible failure mode of the fluid pump.
