分析了常规抽油机目前现状,分别从节电、平衡、维修及增产等方面综合评价了抽油机的节能效果。结果表明,常规机平衡率在70%-85%,下偏杠铃机测得抽油机平衡率均提高到93%-95%以上,平均节电率在24.3%,既可降低了抽油机震动,又降低电机及变压器的能源消耗,节能效果显著。 The current status of the conventional pumping unit is analyzed. The energy saving effect of the pumping unit is evaluated comprehensively from the aspects of energy saving, balance, maintenance and production increase. The results showed that the balance rate of conventional machine was 70% -85%, the balance ratio of pumping unit measured by lower barbell machine was increased to above 93% -95% and the average power saving rate was 24.3% Vibration, but also reduce the energy consumption of motor and transformer, energy-saving effect is remarkable.
