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.
020-34563445Automatic filling scale consists of programmable controllers and Electronic scales to form a two-stage computer control network, connecting field weighing instruments, control computers, PLCs, frequency converters and other equipment with higher intelligence and faster processing speed through field buses.PLC mainly undertakes fault detection, display and alarm of the automatic Filling machine and outputs signals to the frequency converter at the same time, which completes the role of the filling speed.
Liquid filling scale PLC is mainly responsible for manual/automatic processing flow selection, entering the judgment of the liquid level processing, various fault states under the alarm light display processing and control cycle, the liquid level processing is mainly responsible for the collected liquid level information and set value to compare to determine the height of the liquid level in the reaction tank, the liquid level of the level of the signal will be determined by the material pump opening and closing state. When the collected input value exceeds the maximum allowable value of the set liquid level, it will automatically limit it to a reasonable range to avoid abnormal situations. Automatic operation of the work process is the main filling control part, in the absence of other abnormalities and select the manual state, has been in accordance with the requirements of the process cycle back and forth, the value of its parts will be synchronized to display on the weighing interface, so that the control staff reference and monitoring.
Liquid filling machine adopts the most widely used in industrial control to adjust the weight for actual control, according to the weight deviation, adjust the speed of the electronic scale through the frequency converter, adjust the amount of feed to make it equal to the set value, and complete the automatic filling process.
