Abstract: Solar driving auto-balance beam pumping unit was designed and developed to solve the unbalancing conditions of beam pumping unit and reduce the labor intensity of balance-adjusting work. A special tail beam assembly part is installed at the tail of the beam pumping unit that is driven by solar energy and able to adjust the balance weight automatically. The tail beam assembly part includes the solar-driven vernier counterweights and control system. The control system can collect the real-time parameters to figure out the degree of balance and move the counterweights forward and backward according to the degree of balance and adjust the balance of beam pumping unit by means of the wireless transmission method. With a wide scope for balance adjustment, high automation and a modular and plug-in design, this product is highly adaptable for the environments, reliable in safety and stability, and convenient for assembly and calls for a small amount of work for renovation of the work site. It plays an active role in improvement of the field management and reduction of energy consumption.

Key words: pumping unit, tail beam, degree of balance, auto-balance, solar energy

摘要： 为解决油田游梁式抽油机长期处于不平衡状态且人工调整抽油机平衡度费时费力的问题, 研发设计了自 动调平衡抽油机。在常规游梁式抽油机尾部挂接一个尾游梁, 尾游梁上有依靠太阳能储能驱动的游标式配重体, 控制系 统实时、自动检测抽油机平衡度并进行判断, 应用无线控制的方式控制配重游标向前或向后移动, 从而实现抽油机平衡度 的自动调整。该产品具有环境适应能力强、安全平稳可靠、平衡度调节范围大、模块化与插接式设计、自动化程度高、组 装维护方便、现场改造工作量小等技术特点, 为油田提高现场管理水平和节能降耗起到积极的推动作用。
