Ratiometric system for autonomous lubrication of production equipment

A lubrication controller for automatic lubrication of a stuffing box of an oilwell pumping unit, the controller comprising:

• one or more processors comprising an event sequencer, a counter, and a timer, the one or more processor being configured to:
• capture, via the event sequencer, events associated with a plurality of pumping cycles during operation of the stuffing box, wherein each of the events is associated with a completion of a pumping cycle of the oilwell pumping unit, wherein the pumping cycles of the oilwell pumping unit vary throughout a day;
• count, via the counter, the captured events associated with the completion of the plurality of pumping cycles,
• determine, via the counter, an accumulated total of the events associated with the plurality of pumping cycles;
• responsive to the accumulated total of the events being within a specified range, activate, via a lubrication controller, a lubrication pump of a lubrication system for a specified time period as a function of a number of completed pumping cycles of the oilwell pumping unit, the lubricating pump being configured to deliver lubricant to the stuffing box;
• and
• deactivate the lubrication pump when time elapsed measured by the timer after activating the lubrication pump equals to the specified time period.
