摘要
文章介绍了一种挂钩换向链条驱动的长冲程节能抽油机的结构和工作原理。该抽油机采用独特的偏心重力平衡方式和挂钩换向方式。分析了平衡块的受力及挂钩换向冲击力。该机整机结构简单、受力均匀、运行平稳、可靠性高 ,并能实现完全平衡和空载启动。
A new type of energy-saving and long-stroke pumping unit is designed. The unique eccentric gravity-equipoise mechanism and hook-reverse mechanism are adopted in this kind of pumping unit to simplify its structure, average the forces applied to it, make it run steadily and improve its reliability. Moreover, this kind of pumping unit can be started in the condition of zero-load and run in the condition of full-balance.
