摘　　要：针对常规杆式泵泵体密封欠佳、支撑锁紧装置易失效、检泵周期短且检泵作业量大、适用范围有一定限制等问题 ,研制了顶部固定底部密封及顶部密封底部支撑 2种新型杆式抽油泵。研制中采用将“支撑固定”与“密封”分置的结构 ,运用先进的现代设计和制造软件 ,对杆式泵抽油系统和关键零部件进行优化设计 ,对关键件的材料、结构及制造工艺进行了深入研究。现场应用表明 ,新型杆式泵具有较高的可靠性 ,延长了检泵周期 ,提高了泵效 ,降低了检泵作业成本 ,适用于含砂井、含气井、深井、长冲程井、低产井和低液井。In view of the problems in the use of the conventional rod pump,two kinds of new rod pumps are developed.The characteristic of the new pump lies in anchor and attatched seal ring being separately fixed on the top and bottom ends of the pump.The operating principle of the pump is expounded.Then the structure of the pump is optimized,and the material and machining technique of the key parts are investigated.and the equipment for pump manufature and inspection is developed.In the end,the application of the new pump is commented.
