| 摘 要： | 抽油机是把石油从地层提升到地面的重要的机械设备。基于目前液压抽油机在使用过程中存在的高耗能、低效率、换向不平稳等问题,采用恒功率可调变量泵的控制策略,设计一种采用蓄能器回收能量的复合液压缸式抽油机。在AMESim中搭建系统模型,并通过模糊控制优化抽油杆速度特性曲线。仿真结果验证抽油杆换向速度波动超调量由原来的20.6%降到3.82%,蓄能器能够节能48%。

| Abstract: | Pumping unit is an important mechanical equipment for lifting oil from the formation to the ground. Based on the problems of high energy consumption, low efficiency and unstable commutation in the current hydraulic pumping unit, and adopting a constant power adjustable variable pump control strategy, a compound hydraulic cylinder pumping unit using energy accumulator to recover energy is designed. The system model is built in AMESim, and the speed characteristic curve of the sucker rod is optimized by fuzzy control. The results verify that the overshoot of the commutation speed fluctuation of the sucker rod is reduced from 20.6% to 3.82%, and the accumulator can save energy by 48%. |
