Technical scheme for on-site control cabinet of gas steam boiler
The control system is designed according to the operating procedures and control requirements of gas steam boiler, and has the functions of automatic intelligent control and fault protection for gas steam boiler. The main control objects are burners, fans and feed pumps. The system uses HOMEWELL's 5.7 inch color display touch screen as the display and operation platform, and SIEMENS226 PLC as the information processing and central control unit; At the same time, a standard communication interface is reserved, which can be networked with the central computer room to realize building automation and remote monitoring, and can realize networking of multiple units when necessary. The control module adopts the world famous industrial control brand devices, and is embedded with the industrial control software carefully designed by our company and the process structure of the control periphery. The system software not only realizes the general monitoring requirements of gas and steam boiler, such as manual/automatic control, condition monitoring, historical data recording, real-time trend, etc., but also adds the company's achievements in careful analysis and research of boiler accidents in recent years, with rich fault detection, fault alarm, fault processing and other functions, It ensures the safe and reliable operation of the boiler to the maximum extent. At the same time, the company has carried out professional modeling design and numerical control manufacturing for the control cabinet, making the internal structure and external modeling of the control cabinet more consistent with industrial site requirements and ergonomics, making the boiler control more perfect
