Energy Saving Beam Pumping Unit  

Based on beam pumping unit, an new method of design beam hanger to dynamic loading and simulation in software is presented, and beam pumping unit's structure and working principle are introduced in this paper first. Secondly, using the development function of macro command in software, combining with the connect method of bushing and contact through theoretical analysis and calculation to develop beam hangers and managed to get the virtual prototype of beam pumping unit. Finally, using the function of spline to simulate the indicator diagram and loading into suspension point, making dynamic simulation in software. The simulation results reflected the actual motion law of the horse head of beam pumping unit, proved the feasibility of the new modeling method and provided the theory base for further research.
