应用CAD技术及计算机图形显示技术,分析研究了六杆机构的增程式游梁抽油机在给定主体结构参数下,确定满足光杆运动的驴头廓线,曲柄在任一瞬间主体各杆件的角度、角速度、角加速度及驴头悬点速度、加速度的条件,并引用实例进行了计算。推导出驴头悬点速度、加速度和驴头廓线方程。同时,也精确计算了冲程长度、位置因数、扭矩因数、冲程增程系数。作者用同一主参数的非增程式游梁抽油机主体尺寸和性能参数作比较:计算曲柄轴扭矩并进行平衡;在计算机上模拟显示所设计的抽油机的工作过程,以图表或图象形式输出抽油机的各性能参数。
The application of CAD technology and computer graphics display technology, analysis and research of the six-bar mechanism of extended-range beam pumping unit given the main structural parameters, to determine the polished bar head profile of the donkey head, crank at any moment of the main rod Angle, angular velocity, angular acceleration and donkey head hanging point speed, acceleration conditions, and citing examples were calculated. Derived donkey head hanging point speed, acceleration and donkey head profile equation. At the same time, stroke length, position factor, torque factor, and stroke extension coefficient are also precisely calculated. The author compares the body size and performance parameters of the non-bolted pumping unit with the same main parameters: calculates crankshaft torque and balances; simulates the working process of a designed pumping unit on a computer, Form output pumping performance parameters.
