D级空心抽油杆两种制造方法的对比研究

Contrastive Study on Two Manufacturing Methods for G.D Hollow Sucker Rod

介绍了国内D级空心抽油杆以摩擦焊接和热锻成形为关键技术的两种制造方法;依据SY/T 5550—2012,对比分析D级直接连接摩擦焊接式空心抽油杆和D级直接连接镦锻式空心抽油杆的工艺路线、制造难点、产品性能、实际应用情况。结果显示:与D级直接连接摩擦焊接式空心抽油杆相比,D级直接连接镦锻式空心抽油杆的制造工序更少,容易实现自动化,产品各项性能更加稳定,实际应用效果更好。

Elaborated in the essay are the domestically employed two manufacturing methods for the G.D hollow sucker rod, which respectively take friction welding and hot-forging as key techniques. Based on standard SY/T 5550 --2012, a contrastive analysis is conducted in respect of the G.D directly-connected hollow sucker rod made with the friction welding process, and that made with the upsetting process in terms of process routing, manufacture difficulty, product performance, and actual application result. The analysis result shows that compared with the G.D directly-connected hollow sucker rod as made with the friction welding process, the G.D directly-connected hollow sucker rod as made with the upsetting process features such advantages as fewer manufacturing steps, easier realization of automatic production, higher stability of all the product properties, and better operation effectiveness.
