Two pump rotor spinning rod through the implementation drive.
两个泵转子通过旋转的抽油杆实现驱动。
2
ROD encoders are coupled to the drive or the spindle via a separate rotor coupling.
杆编码器耦合到驱动器或通过单独主轴转子耦合。
3
Using the method, the rod fastening rotor dynamics was analyzed, and the discipline of the rod fastening rotor critical speeds increase with total tighten force was abstained.
