Diagnose a Gearbox Overload

Gearbox alarms can come from the design, from a change in the well, or from both. The inputs usually sit in three different places.

PERM-4821 shuts down on gearbox overload alarms. What is the root cause?

Peak torque is at 94% of the gearbox rating at 5.0 SPM. The last fluid shot puts pump fillage at 71%, and the card shows fluid pound on the downstroke. Slowing to 4.0 SPM drops gearbox load to 78% and lifts fillage to 88%, for about 2 bopd less oil.
