Subterranean Pump With Pump Cleaning Mode

摘要

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. The method also includes determining that the pump system should begin operating in a pump clean mode, and implementing the pump clean mode configured in the controller. The method also includes impressing a preset vibration frequency during a portion of a pump stroke of at least one pump cycle. Further, the method calls for determining that the pump clean mode is complete, and returning the pump system to a normal operation mode.

1. A method to dislodge debris from a pump system, the pump system including a down-hole pump coupled by a rod string to an above-ground actuator which is coupled to a controller configured to operate the pump system, the method comprising:
determining that the pump system should begin operating in a pump clean mode; implementing the pump clean mode configured in the controller; impressing a preset vibration frequency during a portion of a pump stroke of at least one pump cycle; determining that the pump clean mode is complete; and returning the pump system to a normal operation mode.
