摘要: 介绍了一种新型平衡方式的游梁式抽油机的基本结构特点及平衡原理,论述了该种抽油机虚拟样机模型的建立和虚拟样机模型检验的基本方法.对虚拟样机模型建立中约束条件的施加原理进行了理论分析,并用虚拟样机软件对其进行了动力学性能分析,给出了主要部件铰接点的受力曲线和曲柄扭矩曲线.分析结果表明,这种抽油机的主要部件铰接点受力状况比原有抽油机有明显的改善,消除了改装前模型中存在的反作用力,曲柄平衡扭矩曲线变化规律未发生改变.但是,这种抽油机的负扭矩明显减小,说明其平衡性能所有改善,有较好的节能效果.

Abstract: The basic constitutive characteristics of a sort of beam-pumping unit with a new balance system were described. The balance principles were discussed, and a virtual prototyping model was established. The assumption terms in the model and the basic methods for examining the virtual prototyping model were discussed. The constraint infliction principles in the establishment of the virtual prototyping model were analyzed. The dynamic property of the new pumping unit was investigated with software for virtual prototyping technology. The curves of force acted on the articulated points of main parts and the torque curve of crank were obtained. The analysis result indicated that the force status on the articulated points of the main parts was obviously improved, and the opposite force existing in the common beam-pumping units was canceled. The torque curve of crank was unchangeable, and the opposite side torque was reduced obviously. The balance function of the new type beam-pumping unit was improved. A good energy-saving result has been obtained.

Key words: beam-pumping unit, new type balance technology, virtual prototyping technology, simulation analysis, dynamics analysis
