    Abstract: A pump has a signal processor, including one forming part of a printed circuit board assembly, that receives signaling containing information about a voltage supplied to a motor to run a particular pump model, and also containing information about whether a current draw of the pump is lower than a predetermined low current level or is higher than a predetermined high current level; and determines whether to shut off the pump after a predetermined time, based on the signaling received. The signal processor provides control signalling to shut off the pump after the predetermined time if the current draw of the pump is lower than the predetermined low current level or is higher than the predetermined high current level, where the predetermined low current level and the predetermined high current level depend on the voltage being supplied to the motor to run the particular pump model.

    Abstract: A liquid pump control system for dry run avoidance and re-prime detection. Pump dry run conditions (such as an empty liquid source tank) can be detected with improved sensitivity by measuring pump cycle speed. Pump cycle speed is determined from sensors including pressure sensors, diaphragm end of stroke indicators, check valve movement sensors, and other techniques. The frequency content of the time-measured signal indicates pump cycle speed. When a dry run condition is detected from an increase in pump speed, a controller closes a valve to reduce pump cycle speed by reducing drive air pressure or by deadheading the pump liquid outlet. When the pump re-primes, the valve is opened, pump cycle speed increases, and pumping volume flow rate increases until a dry run condition is again encountered. Time delays can be introduced to delay shutting down or restarting the pump, for example to give a liquid source tank time to refill. The improved control sensitivity provides improved shut-down and re-start performance, reducing wear on the pump and reducing wasted drive air and energy consumption. The liquid pump control system can be integrated into the pump system, added on to existing pump systems, or located remotely from the pump itself.

    Abstract: A vibrating compressor of the present invention, which comprises a piston driving section for driving a piston by supplying a piston driving force, a displacement detecting section connected in an axial direction of the piston, an upper dead point position detecting section for detecting an upper dead point position based on a piston position signal from the displacement detecting section, and a driving force control section for changing the driving force supplied to the piston by the piston driving section according to a difference between the upper dead point position and a preset upper dead point position reference value immediately after the upper dead point position detecting section detects the upper dead point position, prevents its compression efficiency from decreasing due to stabilization and prevents a device from being damaged. In the vibrating compressor, it is also possible to calculate a stroke based on a detected piston position or to control the driving force based on a detected frequency.

    Abstract: Fluid pounding in a pumpjack is minimized by dictating the length of the run cycles of the pumpjack. The pumpjack is first allowed to pump down until a fluid pounding state is reached, at which time it is shut down. The time it takes to reach this state is monitored. Using the length of time it took to reach the fluid pounding state, the pumpjack is set to run a predetermined number of dictated cycles for a length of time which is 70-99% of the time it took to reach the fluid pounding state. During these predetermined number of cycles if the pumpjack again reaches a fluid pounding state the time is reset based on this new information, and the number of predetermined number of dictated cycles left is finished. After the predetermined number of cycles has finished, the process is repeated by allowing the pumpjack to run to a fluid pounding state.

    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 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.
