First, use Dosing system is a kind of coagulant dosage, mixing, liquid transmission, automatic control in the integration of complete sets of equipment, it is widely used in power plant of raw water, boiler feed water, oil field surface gathering dehydration processing system, petroleum and chemical dosing system and waste water treatment system. Such as adding coagulant, phosphate, ammonia liquid, limewater, corrosion inhibitor, scale inhibitor, algae fungicidal, etc.

    Second, the working principle and structure of dosing device mainly by the solution tank, a stirrer, a metering pump, liquid level meter, electric control cabinet, piping, valves, safety valves, back pressure valve, check valve, a pulsation damper, pressure gauge, Y type filter, a base, a staircase etc.. Dosing device according to the required concentration of medicament, in stirred tank is formulated, after stirring evenly into solution tank, metering pump dosing or specified system to transport the formulated solution. Complete dosing device has the advantages of compact structure, simple operation, safe and convenient use. Dosing device can also according to user requirements to different processes, for the design and configuration of the necessary conditions, to realize the automatic remote control and other functions.
    Third, dosing device selection considerations
    1, a user selects the dosing system, first of all, according to system needs additive solution volume to determine specifications (including metering pump parameters, solution tank and other conditions), again according to the dosing situation, determine the dosing way (generally adopt the way of "one with a prepared").
    2, dosing device is selected according to the need of the material (stainless steel, carbon steel, nonmetal material), metering pump model (diaphragm pump, plunger pump), or to my company to provide the parameters of the drug (name, concentration, temperature, density, viscosity, corrosion, etc.).
    3, dosing system key features:
    Low intensive design, cover an area of an area small, simple structure, stable performance.
    Low measurement precision, convenient adjustment and economical, convenient for installation and maintenance;
    Low pump for suction installation, not easy jam, long trouble-free operation, low operation cost;
    Low corrosion resistance, long service life.
    Low solution case material: PE, 304 stainless steel, 316 stainless steel;
    Low agitator material: stainless steel 304, 304 stainless steel;
    Metering pump flow points material: PP, PVC, PVDF, SS316.
    Scope of application:
    Boiler chemical liquid injection, mainly used in thermal power plant, chemical industry, metallurgy, shipbuilding, central heating, etc. Use the occasion of the boiler.
