<p>The control system of the up-flow pressure screen uses a PLC as the core, connecting field instruments such as inlet dilution water valves, inlet consistency meters, inlet valves, inlet pressure gauges and inlet flow meters to monitor feed parameters in real time.</p><p>At the same time, the pressure gauges and valves on the accepts discharge line, the flow meters and valves on the rejects discharge line, and the heavy-rejects valves on the heavy-rejects line are all controlled by the PLC. A dilution pipeline and water valve on the side of the screen body are used for consistency fine-tuning and cleaning.</p><p>The motor ammeter is also connected to the PLC for load monitoring. When current, pressure or flow is abnormal, the system can alarm or interlock shutdown in time to protect equipment and personnel.</p>
