II18ton/hourEDIControl system for electric deionized water equipment:
Using imported electrical components, the system achieves automatic control; Interlocking protection for each component, and equipped withROAlarm devices for pure water conductivity, high and low pressure, etc. The automatic control of the system adopts an electronic control system to achieve a combination of automatic and manual operation control mode. The standard signals collected by on-site online detection instruments are centrally processed and control signals are output. When the system's water supply is insufficientROThe system automatically takes corresponding actions when the standard for pure water exceeds the standard or when the indicators for ultrapure water exceed the standard. Therefore, it is possible to automatically calculate and provide feedback control for many on-site instruments that do not directly display data.
This device adoptsPLCFully automatic control (excluding chemical cleaning operations),Deionized water equipmentAll water pumps are equipped with one backup and one in use, which can24Continuous automatic operation for hours (i.eAgroup work12Hour, automatic switchingBGroup),Adopting on-site centralized control methodPLCConduct data collection and system control, and the control system can centrally monitor, manage, and automatically control the entire process system in sequence,Multi-media filterThe operation of the activated carbon filter device, backwashing, and dosing of the reverse osmosis device are all carried out byPLCSequential control is automatically performed.
This device is equipped with a touch screen human-machine exchange interface, without the need for a conventional dashboard or analog screen,All operating conditions and historical alarms can be displayed and recorded on the touch screen. Operators can monitor all controlled objects of each process system (including pre-treatment system, reverse osmosis system and other subsystems) of this device on the touch screen, including motor start and stop control, valve opening and closing operation, equipment start status, and remote control/On site switching of status and monitoring of main process parameters, and completion of equipment interlocking protection. The control system adoptsPLCProgrammable controllers, pre-processing, reverse osmosis, and related systems such as water tanks and pumps use hard wiring to connect all control instructions and status signals toPLCOperators can monitor and control the process through the touch screen. In addition to remote control on the touch screen, pumps and pneumatic valves are also equipped with local control switches. Pneumatic valves can be controlled remotely on the solenoid valve box/On site switching is implemented locally. The entire control system can achieve unmanned automatic completion of all functions and ensure the protection function of equipment safety.
