游梁式抽油机的平衡调整是抽油机管理的重要内容之一。对于完全平衡的抽油机来说,上、下冲程曲柄轴的净扭矩或电动机的负载几乎相等,这对于选配更小功率的电动机,节约电能,提高抽油机效率,延长设备使用期限等都具有实际意义。目前使用的平衡调整方法,是依据上、下冲程时电机电流值的变化,凭经验试调平衡块的位置,观察调整后上、下冲程时的电机电流使,直到其值十分接近为止。平衡调整的成功率取决于操作者的熟练程度和工作经验。

The balance adjustment of the beam pumping unit is one of the important contents of the pumping unit management. For a fully balanced pumping unit, the net torque or motor load on the crankshaft in the upper and lower strokes is almost equal, which saves power, increases the efficiency of the pumping unit and prolongs the life of the equipment for motors with lower power. All have practical significance. The current balance adjustment method is based on the upper and lower stroke motor current value changes, empirically test the balance block position, observe the adjusted upper and lower stroke when the motor current, until its value is very close. The success rate of balance adjustment depends on the operator’s proficiency and work experience.
