摘要
游梁抽油机承受一种交变载荷,启动转矩大,在1个周期(1个冲次)内载荷变化很大。游梁抽油机通常用 Y系列电机驱动,其机械特性是硬特性,这使得电机与游梁抽油机匹配不合理,系统效率不高。文章介绍了游梁抽油机负载特点,对合理驱动以及电机节能的问题进行了讨论,提出了应综合考虑的观点。即,首先要考虑合理驱动,其次是电机节能的问题。
Beam pumping unit is a kind of variable load with high starting torque, this kind of load changes a lot in one cycle of stroke. Beam pumping unit is usually driven by Y-series motors. The mechanical feature of Y-series motors is hard, which made the motor match the beam pumping unit irrationally, and then results in the low efficiency of the system. The paper firstly introduces the characteristic of the beam pumping unit, then discusses on rational driving and energy saving of beam pumping unit, finally brings forward an idea of considering the rational driving and energy saving together. Since the beam pumping unit is a complex system consisting of motor, rod, and pump, the rational driving problem is considered firstly, and secondly is the energy saving problem.
