| Abstract: | The indirect measuring model was built, and the computation process of the model was introduced. Synchronization signals were used to obtain the corresponding relationship between the power of the electromotor and the displacement of the pumping rod. The field experiment results were given. The directly and indirectly measured dynamometer cards were compared, and there were tiny errors. It ensured that the indirectly measured dynamometer cards could be used to analyze and diagnose the beam-pumping unit. It was proved that the indirect measuring model was correct and applicable. |
