抽油机平衡状况的好坏,直接影响着抽油机的四连杆机构、减速箱和电动机的效率与寿命,对抽油杆的工作状况也有很大影响。因此,必须予以高度重视。在旋转平衡或者复合平衡方式的抽油机上,调整平衡最方便的方法是调节旋转平衡决的平衡半径。但以往的平衡半径计算公式误差较大。经一年多的实践,摸索出一种用扭矩曲线计算平衡半径的方法。 The balance of the pumping unit is good or bad, which directly affects the efficiency and life of the four-bar linkage, gearbox and motor of the pumping unit and has a great impact on the working condition of the pumping rod. Therefore, we must attach great importance. The most convenient way to adjust the balance is to adjust the balance radius of the balance of the revolution on a pumping unit that is rotating or compounding. However, the previous calculation formula of the equilibrium radius is larger. After more than a year of practice, to explore a method of calculating the equilibrium radius using torque curve.
