AI Technical Summary
Common oil pumping units lack protective features, which can lead to rapid rotation due to inertia when the bearings connecting the walking beams break due to excessive load, affecting operational safety.
The protective pumping unit is designed by combining rubber blocks and spring dampers to prevent the walking beam from rotating and reduce inertia. The elasticity of the rubber blocks prevents the triangular blocks from entering the buffer groove, and the rubber plate squeezes the spring damper to reduce the impact force, thus achieving a safe stop for the walking beam.
It effectively prevents the walking beam from rotating rapidly due to inertia, avoids the breakage of the connecting shaft, and improves the safety of the pumping unit operation.
