弯游梁抽油机连杆抖动问题的分析及结构改进

Analysis and Structural Improvement of Coupler Vibration of Beam Pumping Unit

弯游梁抽油机投入市场使用后部分抽油机出现连杆抖动故障。通过动力特性分析,并结合现场试验,得出连杆抖动问题的原因,并对其结构进行改进。

The connecting rod wobbling failure occurs in some pumping units after the beam pumping unit is put into the market. Through the dynamic characteristics analysis, combined with the field test, the cause of the linkagejitter problem is obtained, and the structure is improved.
