Main Features of Beam Pumping Units

Ⅰ. Basic features of the beam pumping unit


A pumping unit is a machine for oil extraction. Oilfield pumping units are the main lifting equipment in the rod pumping system. They can be divided into the beam and non-beam pumping units according to whether there is a walking beam. Beam pumping units have basic features: simple construction, easy to make and use, and reliable for all-weather operation in the oilfield for the long term.


As traditional pumping units widely used in oilfields, beam pumping units are driven directly by a common AC asynchronous motor. The crank belt with counterbalance leads the sucker rod to push the underground oil-well pump to move up and down in a fixed circle to send the oil to the ground.


A beam pumping unit makes the motor in electric or generating status within one stroke along with the rise and fall of the sucker rod.


Ⅱ. Main features of the beam pumping unit


1. Beam pumping units have rational construction, smooth working, low noise, and are easy to operate and maintain.


2. Walking beam uses a box-type or I-beam steel structure with high strength, good rigidity, and large bearing capacity.


3. The reducer uses herringbone involute or double-arc tooth gear, having high precision, strong bearing capacity, and long working life.


4.  The horsehead of the beam pumping unit can adopt one of the three forms: upturning, racking, and side-tracking.


5. The brake uses external-contacting construction equipped with safety devices, flexible operation, rapid brake, and safety and reliability.


6. The base is connected by an anchor bolt or pressure bar.
