To provide a basis for precise calculation of pumping Unit, it is necessary to make a elastodynamic analysis on the u-nit. 要對抽油機的設計提供較為精確的理論計算依據，必須對抽油機進(jìn)行彈性動(dòng)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. 摘要抽油機中載荷變化大，易引起電動(dòng)機轉速和轉矩的波動(dòng)。
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. 泵基座所采用的鋼筋和錨固螺栓應該能夠與安裝地面結合牢固緊密，確保為泵設備提供堅固可靠的安裝基礎。
