目前 ,孤东采油厂稠油区等部分抽油井负荷较大 ,采用的游梁式抽油机存在平衡不足 (四块平衡配重已调到头 )、平衡效果不好等情况。不仅严重影响曲柄连杆机构、减速器及电动机的效率和寿命 ,同时也降低了抽油杆柱的可靠性。另外 ,还使抽油机的能耗加大 ,致使采油成本提高。为此 At present, some oil wells such as heavy oil areas in Gudong Oil Production Plant are under a heavy load. The beam pumping units adopted have insufficient balance (the four balance weights have been adjusted to the head), and the balance effect is not good. Not only seriously affect the efficiency and life of crank connecting rod mechanism, reducer and motor, but also reduce the reliability of sucker rod. In addition, the energy consumption of the pumping unit is also increased, resulting in higher oil recovery costs. to this end
