Pumping_Unit

The component parts of most of the units are basically the same but the arrangement of the parts differs. Selection of the proper size and type of pumping unit for a particular application is important. Built into the majority of pumping units is some method of counterbalance, which in most cases consists of adjustable weights on the rotating cranks or air pressure pushing up on the walking beam. The counterbalance system, whichever type is used, opposes the weight of the sucker rod string and a portion of the fluid to be lifted. Pumping units generally are typed according to the method of counterbalance. This is true for beam balanced units, air balanced units, conventional crank balanced units, and special geometry (or Mark II) crank balanced units. In addition to the method of counterbalancing, the geometric arrangements of the principal components are distinguishing features. The beam balanced, the conventional crank balanced, and some special geometry units are classified as Class I lever systems because the Samson post bearing (pivot point for the walking beam) is located between the well load and the actuating force of the pitman side members. The air balanced and the Mark II crank counterbalanced units are classified as class III lever systems because the walking beam hinge point is located at the rear of the unit and the actuating force of the pitman side members is located between this pivot point and the well.

Sucker_Rod

The vertical motion of the surface pumping unit is transferred to the subsurface pump by the sucker rods. Two types of sucker rods are in use today-steel rods and fiberglass-reinforced plastic sucker rods. It is estimated that slightly less than 90 % of the rods sold in 1985 were steel rods, while slightly more than 10% were fiber glass rods. Steel rods are manufactured in lengths of 25 or 30 ft. Fiberglass rods are supplied in 37X- or 30-ft lengths. Both types of rods are connected by a 4-in.-long coupling. The pin ends of the sucker rod are threaded into the internal threads of the coupling.

The typical components are:
Barrel: The barrel of an oil well pump is the cylinder into which the well fluid is admitted and displaced by a closely fitted piston or plunger.
Plunger: The pump plunger is a closely fitted tubular piston fitted with a check valve for displacing well fluid from the pump barrel. This may be all metal or equipped with cups, rings, or other soft packing to form a seal with the barrel.
Standing Valve: This is the intake valve of the pump and generally consists of a ball-and-seat-type check valve. The valve assembly remains stationary during the pumping cycle.
Traveling Valve: This is the discharge valve and moves with the plunger of a stationary-barrel pump and with the barrel of a traveling-barrel pump. The entire assembly of a cup-type plunger, or plunger equipped with other type of soft packing, along with the check valve, is often called a traveling valve.
Seating Assembly: A seating assembly is an anchoring device for retaining a rod pump in its working position.
