Design and Research of PDC Bit Temperature Control System

At present, PDC bits are still brazed by artificial flame, and the welding quality is not stable enough. In order to solve this problem, a new type of intelligent temperature control device is developed by combining the brazing technology of double loop PID controller and PDC bit. A multifunctional integrated control method based on embedded real-time operating system RT-Thread is proposed. PID control and layered control are used to detect, control and display the welding process. Experiments show that the device can solve the welding temperature problem of PDC bit.
