Preface: 
In water treatment, chemical, printing and dyeing industry, in water or other liquids often encountered dosing according to a certain proportion of another solution. The production process is continuous, this work must be the same dosing is continuous. Coagulant in water treatment, aid, sterilization. Cooling tower scale inhibitor, chemical, printing and dyeing timing, quantitative investment plus a certain amount of chemical agent, acid and alkali. These are the need for a solution not only to configure, but quantitative timed dosing device agent, and this is our JY series Dosing system possess basic functions. 
JY series Dosing system, continuous years of operation in Jinjiang Amusement Park, Shanghai Friendship Tower and other units, confirmed its reliability and advanced design. We sincerely hope that all over the design of user units to my unit study in order to understand my unit products, enabling us to better serve you. 

Scope of application: 
Coagulant in water treatment, aid, disinfectants, acid and alkali liquid. 
Cooling water, circulating water dosing scale agent. 
Chemical, printing and dyeing, the dosing of acid and alkaline solutions and other solutions. 

Features: 
Stable performance, the solution tank volume, low energy consumption. 
Beautiful appearance, compact structure, small footprint. 
Easy operation and simple maintenance, high energy dosing. 

Process Structure: 
JY Dosing system in three models, there are three major components:. 1. Blender2 solution tank 3. The metering device and dosing settings. 

Now they are discussed below: 
1. Blender: There stir slot machines and mixing device. Its role is to make the required dosage of solute and water (solvent) was according to certain proportion, mixed thoroughly. 
2. solution tank: Use store has been marinated in liquid for dosing spare. 
3. The metering device and dosing method: JY series in two ways: (1) is calculated using the dosing pump. (2) Water injector dosing rotor Flow meter measurement. As pump dosing, Water injector can not, Water injector need to pressure put over 2kg / cm2.
