Abstract: A system and method for activating on a user interface an indicator of a condition of a lubricant in a machine module. The system may comprise a controller and a user interface. The controller may be configured to, for each of a first time window and a second time window: receive a plurality of lubricant characteristics and measured lubricant temperatures, calculate an adjusted lubricant characteristic, and determine a slope based on the plurality of adjusted lubricant characteristics. The controller may further determine a change in slope, and generate a signal to activate the indicator on the user interface based on the change in slope, wherein, if the change in slope exceeds a threshold, the indicator is a lubricant changed indicator.

Abstract: A pumping system for use in a well stimulation application includes a pump controlled by a controller, the controller operating to monitor operation of the pump and determine when cavitation is present or imminent in the pump. When cavitation is present, the controller automatically adjusts an operating condition of the pump reduce pump speed or increase a fluid pressure at the pump inlet.

Abstract: A control system for an engine includes an operational data sensor generating signals indicative of operational data of the engine and a controller communicably coupled with the engine and the operational data sensor. The controller operates the engine based on operational parameters defined by a baseline engine model. The controller receives the signals indicative of the operational data of the engine, and generates a dynamic engine model which defines at least one operational parameter of the engine based on the received operational data of the engine. The controller compares the baseline engine model to the dynamic engine model. The controller determines a difference between the baseline engine model and the dynamic engine model based on the comparison. The controller compares the determined difference to a threshold difference value and operates the engine based on the dynamic engine model, if the determined difference exceeds the threshold difference value.

Abstract: A system for detecting wear or failure of a genset coupling of a genset power system is provided. The system includes a vibration sensor for measuring vibrations, and an additional sensor for measuring an operating condition. A controller is configured to process operating condition data from the additional sensor using a modeling software to generate simulated data. The controller applies time domain information of at least one of the simulated data and vibration sensor data to the modeling software using a machine learning algorithm, and perform a comparison to identify wear or failure of the coupling, wherein, when performing the comparison, the controller compares at least one of: time domain information of the vibration sensor data to time domain information of the simulated data or frequency domain information of the vibration sensor data to frequency domain information of the simulated data, to identify wear or failure of the coupling.

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.

Abstract: A pump monitoring and notification system for a hydraulic pump includes a transmission speed sensor and a controller. The transmission speed sensor is associated with a transmission connected to the pump to determine an output speed of the transmission. The controller is configured to access a transmission threshold, access a time threshold, and determine a rotational speed of the transmission based upon the transmission speed sensor. The controller is further configured to determine a variation in rotational speed of the transmission based upon the rotational speed, compare the variation in rotational speed of the transmission to the transmission threshold, and generate an alert signal when the variation in rotational speed of the transmission exceeds the transmission threshold for a time period exceeding the time threshold.
