Abstract: The device for counting the strokes of a piston sliding within a cylinder comprises a support housing a magnet which generates a magnetic field. The support also houses a sensor arranged to sense the magnetic field, such that the passage of the piston into a position corresponding with the magnet causes a disturbance in the magnetic field, which is sensed by the sensor, to indicate a stroke of the piston.

Abstract: Pump maintenance data associated with each of plural components of each of plural frac pumps of each of plural frac pump transports of a frac fleet is accessed. The pump maintenance data includes usage data of plural well completion operations performed by the frac fleet. The usage data indicates actual component life intervals of each of the plural components and corresponding operating conditions. The pump maintenance data is analyzed to generate a maintenance prediction model that is configured to output for each of the plural components, a predicted component life interval as a function of an operating condition. A current operating condition corresponding to a current well completion operation of the frac fleet is accessed. The maintenance prediction model is applied to generate the predicted component life intervals for each of the plurality of components of the frac fleet based on the current operating condition.

Abstract: An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller operating the pump and communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.

Abstract: There is disclosed a maintenance reminder system for a pump. The system of the invention is coupled to the pump or the control system for the pump and determines the volume of fluid pumped by the pump. In the preferred embodiment, a piston pump is used and piston strokes are counted and converted to total volume of liquid pumped. The computer of the system maintains a database for each maintenance item containing the threshold value for each item and the total volume pumped since the last maintenance. When the total volume exceeds the threshold, a maintenance reminder is displayed and the user may display information from the database as to which item needs service. The computer updates the appropriate fields of the database after the service is performed.
