Application of Network Control Technology in Vulcanizer Control System The vulcanizer control system adopts network control. Guilin Rubber Machinery Factory mentioned it around 1995. At that time, it could not be realized due to the limitation of the programmable logic controller (hereinafter referred to as PLC) network system and various reasons. In view of the various defects of the recording co...
The low-pass filter can absorb most of the " burrs " of the power supply . L1 and L2 in the figure are used to suppress high-frequency differential mode voltage . L1 and L2 are reversely wound on the same magnetic ring with equal-length wires , 50HZ The magnetic fluxes generated by the power frequency current in the magnetic ring cancel each other out, and the magnetic ring will not be saturated.&...
Software process Practical application After the system was installed and debugged, it was officially put into use in October 1999. It has been running stably for more than two years and has calibrated nearly a hundred flowmeters (times) without any problems in the control system. Practice has proved that the system has a high degree of automation, and all performance indicators fully meet t...
Application of PLC, DCS and FCS in metallurgical process control In metallurgical production, the process control system completes the detection, display, recording, adjustment, control, alarm and other functions of the generated process parameters. play an extremely important role. Its characteristic is to control the real-time production process, the control process is complicated, the process l...
The control scale and complexity of the process control system 1. According to the control scale and complexity of the process control system For different metallurgical production processes, the control scale and complexity of the process control system are different. Usually, DCS is preferred when the process control system is large in scale and high in complexity. Because the system is develope...
