Description
8404-1002 WOODWARD Speed Sensor Full Series
Non differential regulation is mainly used for constant speed control and is suitable for single machine operation or multiple prime movers working together in an isolated power grid. Differential regulation provides more control flexibility.
further enhancing its performance and application range.
rich additional functions, and high-precision output signals. Whether it is in the fields of generator sets, compressors, pump stations, or ships and locomotives, it can effectively ensure the stable operation of equipment within the set range.
power measurement level 1, editable screen, multi interface toolkit connection, etc. All details can be found in Woodward easyYgen manual 37582A
The rated operating temperature range of this model is -20 to 70 ° C; the rated temperature range of the LT model is -40 to 70 ° C, suitable for outdoor use.
8404-1002 is equipped with a monitor (not available on the 3100 model) and is designed for front panel installation.
The built-in HMI has a color LCD and soft keys (now with dedicated buttons) for direct control of the 8404-1002 device. Multi level password protection can prevent unauthorized changes.
The generator set has four operating modes and the option to configure a manual circuit breaker control device.

Coke oven is a key in the coking industry. The temperature in the oven directly affects the quality of the refining coke. Therefore, we must ensure that the temperature in the oven is stable within a reliable range. Therefore, we must control the pressure in the coke oven flue and gas main pipe. We adopt a composite control method, that is, feedforward plus feedback/manual switching to achieve control requirements. The liquid level in the elution benzene condensate storage tank, the temperature at the top of the ammonium distillation tower and the pH value of the ammonium water are automatically adjusted. Since the SP value (set value) of many adjustment loops is an uncertain number , need to be based on different requirements in different periods; in the design of PID adjustment and manual/automatic switching, we designed the SP to track the PV when manual, and adjust the process value according to the SP value during automatic switching, so that when the operator switches from manual Switch the adjustment process value to automatic and you can adjust it immediately with this process value. It is conducive to operators to further explore ways to improve work efficiency.On the operation interface of the operator station, trend charts of important variables such as “ammonium distillation tower bottom pressure” and “regeneration tower liquid level” are created, which is helpful for operators to intuitively observe the changing trends of important data. We use the signal sequence function to record the changing process of each operation. Its fastest scanning period is two milliseconds, so that we can clearly remember the changing sequence of data. When an accident occurs, we can refer to these data to analyze the cause of the accident. . We have also created a database to cumulatively record important variables in the process of “coal preparation”, “coke screening”, “tank area”, etc. Enterprises can analyze the production process based on the data, optimize the production process, and continuously improve efficiency.The OPC standard software interface is designed in the system, which provides the basis for the enterprise”s on-site data management. At the same time, it provides guarantee for enterprises to realize information management.7. SummaryNow the plant has been put into production. According to the design requirements, the entire system is designed to produce 1 million tons of coke per year. The DCS control system provides guarantee for achieving this goal. The ABB AC800F distributed control system operates stably and reliably, and at the same time brings convenience to the enterprise”s information management. Practice has proven that the DCS control system has made contributions to improving labor productivity, improving product quality, and avoiding accidents. It has brought considerable economic benefits to the enterprise and achieved user satisfaction.
