摘 要
本文根据游梁式抽油机四连杆机构的几何关系和运动特点,建立了游梁的摆动方程,并精确计算出游梁式抽油机悬点运动参数;考虑抽油机光杆静载荷和惯性载荷及运动机构的重力和惯性情况,建立了抽油机系统相对曲柄的等效动力学模型,并求出具有动平衡特征的曲柄轴净扭矩;根据抽油机皮带传动特点和力学分析,建立了一种简便的皮带传动效率计算模型,为分析抽油机瞬时工作参数提供了理论支持;重新定义了周期载荷系数计算储电动机额定功率,并以常规游梁式抽油机,调径变矩式抽油机为例,编写计算机程序,实现了重要参数的计算,并绘出关键曲线,由此比较得出了节能抽油机的优点.文中还对其他节能抽油机进行了简要介绍.
关键词:速度;加速度;扭矩;周期载荷系数;调径变矩式
ABSTRACT
In this paper based on the unique geometry and mechanical movement of beam pumping unit,we have presented a simple swing equation and computed motorial parameter;meanwhile under the conditions of the static load and inertial load of the polished-rod of a conventional pumping unit,we have also presented on equivalent dynamic model of the pumping unit system and the type-curves of net torque of the crankshaft with the characteristic of inertial counterbalance have been computed;Based on features and mechanical analysis of belt,a simple model for calculating belt transmission efficiency is developed the model can provide a theoretical base for study on the other transient variable of beam pumping unit;the cyclic loading coefficients is defined once and compute the nominal Power of the motor; at last we compare the beam pumping unit and the adjustable diameter and changeable toque pumping unit, based on this a program have been finished,and we also introduce other power saving pumping units.
Keywords:velocity; acceleration; toque; the cyclic loading coefficients; adjustable diameter and changeable toque pumping unit
