n: a machine designed specifically for sucker rod pumping. An engine or motor (prime mover) is mounted on the unit to power a rotating crank. The crank moves a horizontal member (walking beam) up and down to produce reciprocating motion. This reciprocating motion operates the pump. Compare pump jack.

n: the large circular gear in a mud pump that is driven by the prime mover and that, in turn, drives the connecting rods.

n: The big and round gear installed in drilling pump.

n: a reduction unit between a prime mover and a beam pumping unit that reduces the prime movers output speed by means of a series of chains.

n: a coupling used to connect and disconnect a driving and a driven part of a mechanism, especially a coupling that permits the former part to engage the latter gradually and without shock. In the oilfield, a clutch permits gradual engaging and disengaging of the equipment driven by a prime mover. v: to engage or disengage a clutch.

n: A fuel used to power the prime movers on the rig.

n: a straightforward connection that makes the speeds of a prime mover and a driven machine identical.

n: a structure erected to contain petroleum or a petroleum-fed fire in case a storage vessel ruptures or collapses. Usually a dike is built around the petroleum storage tank and a steel or stone wall is put up between the prime movers and the oil pumps in a pipeline pumping station.

n: a fluid connection between a prime mover and the machine it drives;it uses the action of liquid moving against blades to drive the machine. Also called fluid coupling.

n: certain hydraulic transmision assembly that composed of two impeller of turbine and pump.

n: a governor that maintains a constant speed of the prime mover regardless of the load applied, within the capacity of the prime mover.

n: a method of lifting oil out of several wells in a field. A pump is placed at every well;however, all of the pumps are powered by a single prime mover (engine or motor) instead of each pumps being powered individually.
