【Introduction】

In water treatment, petroleum, chemical, electric power, metallurgy, environmental engineering and other industries, need to be a continuous and uniform liquid injected into the other automatically becomes a liquid mixture, or to join the existing pharmaceutical and liquid A chemical reaction to some ingredient, due to its production process is continuous, so this work must be the same dosing is continuous, to achieve the desired process requirements, in case conditions change, the dosage of the pharmaceutical to Automatic adjustment and control, so in the automatic dosing devices, the use of advanced automatic control, quantitative control system to regularly dosing。

【Device structure and composition】

Automatic dosing equipment consists of add kits, dosing pumps, automatic control systems, safety valves, buffers, filters, instrumentation, control valves and other components, a variety of devices installed in a fixed bottom shelf. The structure consists of three parts：
1、The first part is the mechanical parts, mainly by liquid containers, thin liquid stirred tank, metering pumps, piping valves, platform support, fences, etc；
2、The second part is mainly composed of electrical control mixer, level gauge, electrical parts, control cabinet and wire and cable；
3、The third part equipment, including pipe valves: pressure gauge, check valves, safety valves, piping, cont。ol valves, filters and so on。

【Applications Field】

Water treatment, petroleum, chemical, electric power, metallurgy, environmental engineering and other industries, widely used。
