The sucker rod is a slender rod of the pumping well, it is connected to the polished rod on the top, and the pump is connected to the bottom to transmit power. During the working process, the sucker rod has to bear huge friction force. For this reason, we often use medium-frequency induction heating equipment for quenching heat treatment to improve the hardness and wear resistance of the sucker rod, and the effect is very good.
After the sucker rod is quenched by intermediate frequency induction heating equipment, there will be a hardened layer on its surface, about 2-3mm. It is precisely because of this layer of hardened layer that the hardness and wear resistance of the sucker rod are greatly improved. Satisfied the working requirements of the sucker rod. The sucker rods we usually see can be quenched by 200kw medium frequency induction heating equipment.
When the medium frequency induction heating equipment performs quenching heat treatment on the sucker rod, the heating speed is very fast, which effectively avoids the phenomenon of oxidation and decarburization of the sucker rod during the quenching process, ensures the quenching effect of the sucker rod, and makes the pumping after quenching There is a thicker ductile area under the hard layer on the surface of the oil rod, which has better compressive internal stress, so that the fatigue resistance and breaking capacity of the sucker rod are higher. Even better, the medium-frequency induction heating equipment will not produce noise and dust when quenching and heat-treating the workpiece, which greatly improves the working environment of the workers. It meets the national policy requirements and is strongly advocated by the country.
