PH automatic dosing device works because the water treatment process requirements offer automatic dosing device, the water PH value often needs to be controlled within a certain range of PH value, to the water, adding acid or base to meet this requirement is the most direct and effective approach. Commonly used acid and alkali neutralizing agents include sulfuric acid, hydrochloric acid, ammonia, sodium hydroxide, calcium hydroxide, sodium carbonate and the like. Detected by the line pH sensor and pH value of the pool or chemical reaction kettle liquid and transfer to the automatic dosing unit pH Monitor spot, according to production requirements, the pH monitor is set high, low control point After, pH pH monitor the input signal and the high and low set value output switching signal or proportional control signal to the control box automatic dosing device pictures from the control box to adjust the amount of control the metering pump acid or alkali amount . The system does not require personnel to operate, automatic control, thus greatly improving the accuracy and efficiency of dosing, and ensure safe production and stable processes and personnel. Automatic dosing device is a set of administration, stirring to dissolve, transmission fluid, automatic intelligent control system equipment in one of the sets, it has been widely used in municipal water treatment process engineering and industry of water treatment projects, wastewater treatment and sludge dewatering systems, thermal power plants and the petrochemical industry furnace water systems, oil field gathering dewatering systems, metallurgy, mining, chemical, mining and other industries in the process dosing system. Automatic dosing device for preparing raw material powder drug can also be used to dilute liquid Pharmacy. Automatic dosing device mainly consists of frame, powder medicament storage tank, screw feeder, immersion system apparatus and stirred to dissolve and storage tanks, piping systems, PLC electric control system, pneumatic control systems, security systems, liquid pumps, etc. Composition (can be formulated according to the actual needs of the user). Automatic dosing device effects, rich students (certification), Guangdong automatic dosing device provided by the Environmental Protection Engineering Co., Ltd. Guangzhou Fu students.
