The control system consists of upper and lower computers. The upper computer is an industrial computer. The operation screen is more friendly and humanized. At the same time, it also has the characteristics of reliable operation and strong anti-interference ability. The lower computer is a PLC system, which has shock resistance and impact resistance. The upper computer is installed on the operating table, and the display screen can provide users with a good human-machine interface.Vacuum heat treatment of corrugated spring bayonet connector It mainly consists of the following subsystems: Transmission control system The transmission control system is a continuous production process of film loading-heating-cooling-removing film. Its transmission program and process parameters are different due to different glass thicknesses, all of which are automatically controlled by PLC. The transmission process status can be displayed through the terminal display. monitor.Reaction sintering of silicon carbide ceramics temperature control system The temperature control uses a temperature control module. Each heating zone is equipped with a thermocouple. According to the thickness and variety of the glass, the temperature is set on the operation terminal. The temperature control module calculates and outputs a control signal to the solid state according to the measured temperature. The relay is used to control the output power of the heater. It adopts a set of advanced automatic optimization temperature algorithm, which can realize the PID self-tuning function and fuzzy control function, and the temperature control is very accurate. The solid state relay has stable performance and reliable operation, so the temperature control system is very reliable.Analysis of carbon content on the surface of carburized parts
