Pumping Unit Suspension Point Direction Balance Theory Analysis Method and Effect Evaluation

Abstract:

In order to reduce the adverse effect of suspension point dynamic load on pumping unit system, according to the suspension point balance principle of conventional type pumping unit, the suspension point direction balance designing scheme is determined. Take CYJ10-3-37HB pumping unit as research object. Establish the virtual prototype simulation analysis model of conventional pumping unit by suspension point direction balance before and after the balance. Through the contrastive analysis of simulation results, the effect of load reduction and energy saving after the pumping unit by suspension point direction balance is determined. The simulation results show that the reduce rate of pumping unit maximum polished rod load is 29.4%, the reduce rate of RMS torque is 15.8%, the load reduction and energy saving effect of suspension point direction balance is obviously. It laid a theoretical basis for the suspension point direction balance device in engineering practice application.
