With the rapid development of the electronic information industry, electronic product replacement is accelerating, as the carrier of modern electronic products printed circuit board (Printed Circuit Board, PCB) demand is also increasing. Currently in the PCB production process, almost every process requires the use of tap water and chemical tanks, operations in the chemical tanks will also have a multi-channel overflow water washing, water consumption is quite large, the water used up are also directly discharged into the sewage pipe to the sewage treatment plant, that is, wastewater emissions have also increased.
Currently the country's water control indicators are becoming more and more stringent, the PCB industry is no exception, all PCB manufacturing enterprises daily wastewater emissions have to be approved by the local environmental protection department, can never be discharged over the capacity, that is, PCB manufacturing enterprises want to expand the production, expanding the scale of the only way is to conserve water, so that the increase in production does not increase the pollution.
Audiowell launched a water-saving control module, will be based on the required flow rate of the production line, real-time measurement of the feedback flow, the ball valve for rapid adjustment, the use of water-saving control module of the instantaneous flow rate control. Under the premise of ensuring the quality of PCB products, it can further control water resources, reduce sewage discharge, and provide protection for the enterprise to expand production.
The water-saving control module is equipped with PH value sensor and conductivity sensor, which take the PH value or conductivity of the liquid as the reference value. When the PH value or conductivity of the cleaning tank is not in the set range, the water-saving control module will control the ball valve to adjust the injection speed to dilute the PH value or conductivity of the liquid to within the set range, and then automatically control the ball valve to reset to the injection speed after it reaches the set range.
Water-saving control module can also be built through the 4G or NB network, the collected data will be transmitted to the industrial Internet platform, the visual interface can always grasp the water-saving control module's operating status and parameters, but also can be controlled remotely.
The water saving control module consists of ultrasonic flow meter, stepless variable speed ball valve, display screen and main control module.
