A New Kind of Long Stroke Wheel Style Pumping Unit

In this paper, the way and process on how to finish the simulation of the three-dimensional dynamics for the long stroke pumping unit is showed. While the simulation software Pro/MECHANICA was used here, we made the dynamics realistic model for the pumping unit, then we proceeded the simulation analyses for the long stroke pumping unit. The conclusion went that this kind of pumping unit had a reasonable structure and low pumping speed long stroke as well as high pumping efficiency, also it was quite easy for maintenance operation, which would lead to a prominence low lifting cost.
