Title: PRESSURE PUMP VALVE MONITORING SYSTEM
Abstract:
A monitoring system may include a position sensor, a strain gauge, and a computing device for determining the condition of a valve in a chamber of a pump using strain measurements. The strain gauge may determine strain in the chamber. The position sensor may determine the position of a crankshaft coupled to a plunger in the chamber. The computing device may receive signals generated by the strain gauge and the position sensor related to the strain in the chamber and the position of the crankshaft, respectively, and may process the signals to determine delays in the actuation of the valves.
