游梁式抽油机井皮带滑动效率的仿真研究
Simulation of Sliding Efficiency for Belt Driving in Beam Pumping Units
摘要
Abstract
Considering great fluctuation of load torque of the belt driving device in a beam pumping unit,belt longitudinal vibration of beam pumping unit,the relative sliding speed between belt and pulley and instantaneous sliding efficiency were researched. The belt was simplified to elastic body of longitudinal vibration,the mechanical model of longitudinal vibration of the belt which was excited by alternating friction was established,and the mathematical model of the wave equation form was built. The numerical simulation model of wave equation was established with the superposition method of vibration mode. Simulation model of belt instantaneous sliding speed relative to pulley and simulation model of belt instantaneous sliding efficiency were established. The factors of affecting sliding efficiency were pointed out, such as oscillation amplitude of alternating torque and initial tension of belt in beam pumping unit. The following conclusions are obtained by the simulation results:load torque fluctuations of beam pumping unit will lead to lower sliding efficiency;sliding efficiency of belt driving decreases obviously when crank torque of beam pumping units is negative;under condition that the beam pumping unit operates regularly,the belt efficiency increases with the increasing of initial tension.关键词
