To provide a basis for precise calculation of pumping Unit, it is necessary to make a elastodynamic analysis on the u-nit. 要对抽油机的设计提供较为精确的理论计算依据，必须对抽油机进行弹性动力分析。
This paper mainly focuses on the fluctuation of velocity and torque of the electromotor because of the variational load in the pumping unit equipment. 摘要抽油机中载荷变化大，易引起电动机转速和转矩的波动。
Rebar and anchor bolts used in the pump base shall be sufficiently tied to the mounting floor to ensure a rigid, stable mounting surface for the pump unit. 泵基座所采用的钢筋和锚固螺栓应该能够与安装地面结合牢固紧密，确保为泵设备提供坚固可靠的安装基础。
