Abstract

See full text

A method to dislodge debris from a pump system in which the pump system includes a down-hole pump coupled by a rod string to an above-ground pump actuator, which is coupled to a controller configured to operate the pump system, and where the actuator has an adjustable stroke length. The method also includes determining that the pump system should begin operating in a pump clean mode, implementing the pump clean mode configured in the controller, and cycling the pump actuator at a preset command speed using a preset starting stroke length, preset acceleration rate and a preset deceleration rate. The method also includes continuing to cycle the pump actuator while incrementally decreasing the stroke length by a preset stroke length increment resulting in increased pump cycling frequencies. Further, the method calls for determining that the pump clean mode is complete, and returning the pump system to a normal operation mode.
