Research Of Water Plant Dosing System Based On Magnetic Pump

Water plant's coagulation process is a critical working procedure of producingtap water. The basic request of dosing system to dosing device are high-accuracy forcontrolling and economical for applying. As the key equipment in the dosing system,diaphragm metric pump system is very complex, with the fittings expensive and themaintenances trouble. The topic combines the present condition that the control ofmodem network developments continuously toward the floor equipments, and blendsthe forerunner theories of controlling. Thus, the idea of magnetic pump dosing systemis put forward, which is matching the dosing development's trend and has prospect.Compared with metric pump, magnetic pump is more younger in the family ofindustrial pumps. Sparing no efforts, the thesis inquires into the basic techniques ofmagnetic pump and its development thoroughly. Standing on the position that thepumps applied to dosing system, the thesis carries on an overall comparison betweenthem about functions. Therefore, we can understand the latent advantages frommagnetic pump in dosing system.The paper has elaborated the chemical measure principls of magnetic pump, andit's dosing system has set up. By forming a close-loop system through frequencyinverter and flow meter, the dosing auto control system comes true. With the mixturesystem and the dosing system integrated organically, the discharge to regulating flowexpanses more. In the meantime, based on its performances and characteristics ofmagnetic pump, this system actualizes safety interlocking device, insuring magneticpump running steadily and for long time. Ask for adjustments and experiments onmagnetic pump, through analyzing the data, the results show that magnetic pump canmake up the shorts of metric pump and satisfy the needs in chemical dosing systemsuccessfully, which is of practical significance.Technical development never stops. Also the dosing auto control devicedevelops along with it continuously and inevitably. Magnetic pump system is easy tocontrol, simply in maintenance and low in cost. Which has achieved good economicaland environmental benefits since it is put into practice in water factory, and bringforward a new idea to deal with the complicated dosing auto control problem.
