基于Flow Simulation的抽油杆扶正器对螺杆泵扬程影响规律数值模拟研究

Numerical Simulation on the Regular Pattern of Influence With Sucker Rod Centralizer of Progressing Cavity Pump Based on Flow Simulation

螺杆泵是一种渐进式容积泵,为防止抽油杆旋转对油管的偏磨,减少泵的功率损失,抽油杆上安装了抽油杆扶正器。文中用Solid Works对扶正器进行三维建模,分析了扶正器对螺杆泵扬程的影响。

Progressing cavity pump is a progressive displacement pump. In order to prevent the sucker rod eccentric rotation wear and reduce the power loss,the sucker rod centralizers are installed. The model of sucker rod centralizers is built in Solid Works. The effects of sucker rod centralizers on progressing cavity pump are analyzed.
