摘　　要：针对游梁式抽油机能耗严重、电机运行效率低的问题,提出一种新型混合动力游梁式抽油机结构方案。该方案采用机械-液压转矩耦合传动机构,通过液压系统实现能量存储与释放,其电机输出功率平稳,运行效率高。建立该系统数学模型和能量损失模型,并搭建原理验证实验平台。通过实验和仿真对比,验证机械-液压传动系统能量调节的有效性。提出该系统参数设计方法,并通过对系统参数的研究,得到在不同液压系统组合结构下抽油机的损失功率。研究结果表明,采用变量泵-变量马达组合方案可实现能量损失最小。To solve the problems of serious energy consumption and low electromotor running efficiency of beam pumping unit,a new structural scheme of hybrid power beam pumping unit was proposed.In this scheme,the mechanical-hydraulic torque coupling transmission mechanism was adopted,the energy storage and release was realized through the hydraulic system.The output power of the motor was stable and the operation efficiency was high.The mathematical model and energy loss model of the system were established,and the principle verification experiment platform was established.The effectiveness of the energy regulation of the mechanical-hydraulic system was verified through comparing experiment and simulation.The design method of the system parameters was put forward,and the lost power of the pumping unit was obtained under different hydraulic system combination structures by studying the system parameters.The study results show that the energy loss can be minimized by using variable pump-variable motor combination scheme.
