【摘要】 为了改善抽油机的平衡调节,本文提出了平衡重前置的安装方式。从抽油机平衡效果及电机耗电量两方面对比,证明了平衡重前置可减小曲柄轴负扭矩及峰值扭矩,降低功率消耗。本文还推荐了平衡重前置调节平衡的计算公式。更多还原

【Abstract】 In order to improve the counterbalance effect of pumping units, this paper represents a method of installation with forward offset counterweight. It has been proved that the negative torque and peak torque rating of the Crankshaft are reduced and energy consumption decreased. In addition, formulas for counterbalance adjustment in such a case are given in this paper.更多还原
