The beam pumping unit serves as the core surface drive equipment in an oilfield's mechanical lifting system. Utilizing a four-bar linkage mechanism (crank, connecting rod, and walking beam), it converts the motor's rotary motion into the reciprocating vertical motion of the horsehead. This action drives the downhole sucker rod and pump to continuously lift crude oil to the surface. The unit incorporates a counterbalance system to minimize peak loads, reduce motor power fluctuations, and enhance overall energy efficiency and stability. Known for its robust structure and reliable transmission, it is easy to operate and maintain. It is highly adaptable to harsh field conditions—including extreme temperatures and sandstorms—and meets the production demands of wells with varying depths, fluid rates, and oil properties. As a vital piece of artificial lift equipment, it is extensively deployed across oilfields worldwide.
The beam pumping unit features a stable tower-type or three-leg support structure and relies on a crank-connecting rod-beam mechanism for motion conversion. The electric motor serves as the power source; after speed reduction and torque amplification by the gearbox, it drives the crank to rotate. The crank, via the connecting rod, pushes the walking beam to oscillate around the support shaft (support shaft). The horsehead moves up and down with the beam, driving the downhole sucker rod string and pump plunger to complete the pumping cycle, thereby lifting crude oil from the formation to the surface.
Converts the rotary motion of the motor into the reciprocating linear motion of the horsehead. This motion conversion principle is mature, and the transmission is direct.
Features a stable tower-type or three-leg design with the support shaft, walking beam, and base as the main components. It offers high structural strength and stability, capable of withstanding significant alternating loads and impacts.
Primarily utilizes crank balance, beam balance, or compound balance to counterbalance the reciprocating load of the sucker rod string and reduce motor peak power demand.
The unit has a compact structure with strong parts commonality and interchangeability. This facilitates manufacturing, installation, maintenance, and replacement, enabling the unit to adapt to complex field conditions.
