Urea filling scale adopts PLC to coordinate the whole control of bucket positioning, roller table operation, weighing filling, tank material and so on. The man-machine interface is used for manual, automatic and other modes of control, and the high-precision weighing module and high-stability weighing instrument are selected to control the filling process, which fully meets the precision and speed requirements of the system.
020-34563445The urea drum scale is composed of a programmable controller and an Electronic scale to form a two-level computer control network. It is connected to on-site weighing instruments, control computers, PLCS, frequency converters and other intelligent and fast processing devices through a fieldbus. The PLC mainly undertakes the function of fault detection, display and alarm for the automatic Filling machine, and simultaneously outputs signals to the frequency converter, which then completes the filling speed.
The PLC of the liquid filling scale is mainly responsible for the selection of manual/automatic processing procedures, the judgment of entering the liquid level processing, the display and processing of alarm lights under various fault conditions, and the control cycle. The liquid level processing is mainly responsible for determining the height of the liquid level in the material reaction tank by comparing the collected liquid level high and low value information with the set value. The high or low signal of the liquid level will determine the opening and closing state of the material pump. When the collected input values exceed the maximum allowable value of the set liquid level, they will be automatically limited within a reasonable range to prevent abnormal situations. The automatic operation working process is the main filling control part. When no other abnormal situations occur and the manual mode is selected, it will continuously cycle back and forth according to the requirements of the process flow. The values of each part will be synchronously displayed on the weighing interface for reference and monitoring by the control personnel.
The Liquid filling machine adopts the most widely used weight adjustment method in industrial control for actual control. According to the weight deviation, the speed of the electronic scale is adjusted through the frequency converter to make the given amount equal to the set value, thus completing the automatic filling process.
