Beam Pumping Unit

1. API Spec 11E pumping unit 2.Conventional beam pumping unit 3. simple, stable, convenient, long service life pumping unit

Modularization and virtual manufacturing technology have been adopted in the process of designing, product structure has been optimized, and the parts are of high standardization, universalization, and serialization.

characteristics:

"H" section steel structure, high strength and nice load bearing capacity. Middle width roller center bearing, strong endurance. Self-aligning bearings are adopted in equalizer beam bearing and crank pin bearing, reducing installationerrors and the vibration when pumping unit is operating.Hanging structure of the horsehead is “self-abdicating” mechanism , facilitating wellhead operations.Gear reducer adopts herringbone involute or double circular toothed gear, high precision, nice load bearing capacity, and long service life.Brake adopts internal expanding or external structure . The brake has safety devices, which can brake quickly, safe and reliable.Lubrication grease is supplied by central lubrication system, reducing manual maintenance.The unit has comprehensive safety protection, the ladder and all moving parts are equipped with safety guard and safety fences.
