Abstract
A monitoring system may include strain gauges and position sensors corresponding to multiple pressure pumps. The strain gauge for each pressure pump may measure the strain in a respective chamber of each pump. The position sensor for each pump may measure the position of a rotating member of each pump. The monitoring system may also include one or more computing devices for determining actuation delays associated with valves corresponding to the respective chamber of each pump using expected actuation points and actual actuation points of the valves. The computing devices may compare the actuation points for the valves of all of the pressure pumps to determine a condition of a valve in one of the pressure pumps.
