Research on counterweight selection and movement control of traction oil pumping unit

Traction oil pumping unit is a new oil pumping device with high efficiency. The assessment of counterweight system is important for the selection of unit key parts such as the rope, reducer and motor. In this paper, the movement of the new traction oil pumping unit and its loading condition is systematically analyzed, the composition of the suspension point load is studied and the calculation method is obtained, then combining with an example the suspension point load is calculated and its indicator diagram is given. This paper studies on the optimization about the counterweight system, the conversion process from start to stop and the variable frequency speed regulation technology. Counterweight is ensured and the energy conservation has been reduced obviously.
