Equipment Introduction
Current walking-beam pumping unit is one of the main oil pump units. It consists of a traction head- walking beam- connection rod- crank gear, reduction box, power equipment and auxiliary devices.

On operation status, motor starts traction and goes through the reduction box, crank gear, then turns into the up and down movement of the traction head. The traction head pulls the plunger of oil pumps in well up and down movement through the connection rod and sucker rod.

Characteristics
1. Unit with reasonable structure, reliable operation, low noise, convenience and maintenance
2. Walking-beam is of box-type or joist steel structure, with high intensity, good stiffness and bearing capacity
3. Reduction box adopts a herringbone design and double circle-arc tooth form gear. It can achieve high machining precision, strong bearing capacity and long lifetime.
4. Traction head can perform the movement with the one of the upturning, up-hanging and side-turning.
5. Braking features an anti-embrace structure for safe and reliable performance.

Application Conditions
In actual application, the energy feedback unit (brake unit or resistance) should be added to avoid piston rod’s down speed driven by traction head over the motor run speed to generate electricity to impact inverter.
