自动化系统在水处理设备中的应用

Early in water treatment equipment adopts relays control, hard, easy oxidation, connector contact cause, control, and cannot achieve visual ineffectiveness real-time monitoring function.But now some regions with mitsubishi PLC control, because of the small areas, performance enough points, stability, also cannot satisfy the requirement of enterprise. Therefore, this paper proposes using Siemens S7-200 PLC and touch screen water treatment MP22 Siemens control system to control and water treatment equipment, real-time monitoring of the scheme. This plan has realized the water treatment system, automatic operation, interlock alarming, manual control and the integration of function, the biggest radiometer control reduced between staff, reduced cost, stable performance, high efficiency and convenient maintenance, beer, beverage, pharmaceutical and automobile coating processing industries widely.
