Quanzhou Fu students certified automatic dosing device automatic dosing device Which is good

Automatic dosing device works dosing pump driven by the AC drive motor, the drug is injected into the liquid, the drug concentration is detector test, the detector will be proportional to the concentration of the electrical signal is input to the regulator with the set value comparison give the error signal, the error signal conditioner according to process requirements proportional, integral calculation, the calculation result signal is sent to the inverter, the inverter will adjust output power adjustment signal to change the motor operating frequency, the motor speed changes, injecting a liquid solution concentration change, the medicine concentration at best. Scope of industrial cooling water circulation system, air conditioning and refrigeration systems, heat exchange system, hot water boiler system, production and domestic hot water supply system. Automatic administration dissolved devices at the optimum working conditions, water flow and output flow equilibrium solution, dissolving tank liquid level substantially constant. When the level reaches the upper limit, the water dispensing suspended. When the level dropped in position, the water dispensing resume. When the level reaches the set limit position, the system will be audible alarm signal through the electrical control box and automatically shut down. Is an automatic dosing and batch polymer solution preparation equipment, mainly used in precipitation, coagulation, flotation, such as sewage treatment sludge dewatering process, for automatic preparation and dosing coagulant or flocculant use. Preparation of the raw material is a powder medicament, such as polyacrylamide (PAM) and the like.
