抽油泵衬套渗碳淬火工艺的改进

Carburizing and quenching for sucker rod pump liners

介绍了抽油泵衬套渗碳后直接淬火处理工艺。实践表明,这种工艺与国内大多数厂家现用的二次加热淬火工艺相比,可节省处理时间35小时,降低能耗47％,而且衬套变形量小,硬度略有提高,能满足现场使用要求,获得了显著的经济效益。

This article recommends the process of direct quenching after carburizing for sucker rod pump liners. The application of this process shows that, in comparison with the two-step quenching process adopted by most of the domestic rod pump manufacturers, the duration of treatment is by 35 hours shortened and the energy consumption by 47% reduced, and the treated liners present small deformation and somewhat higher surface hardness.
