An automated system of equipment for accurately dosing certain chemical reagents into the water being treated (“source water”). The main task is “accurate, continuous, automatic” dosing of reagents, replacing the unstable and ineffective manual method.
1. Preparation of the solution: a specified amount of reagent and water is added manually or automatically to the tank for dissolving reagents, and the stirrer is turned on to prepare a solution of the required concentration.
2. Monitoring: online devices (flow meters, pH meters) monitor the flow and quality parameters of source water in real time.
3. Feedback: The measured signals are transmitted to the PLC controller.
4. Decision making and execution: The PLC, in accordance with a given program (for example, dosing proportional to flow or pH control), calculates the required amount of reagent and then issues a signal to control the stroke or frequency of the dosing pump.
5. Dosing: The dosing pump accurately pumps the reagent solution from the tank and injects it into the source water pipeline through the injection valve.
6. Mixing and reaction: the reagent is thoroughly mixed with the source water in the pipeline, entering into a chemical reaction (neutralization, coagulation, flocculation, etc.).
Highly integrated modular equipment with fully automated control function.
Compact size, ease of operation, ease of installation - only water and power supply are required on site.
The reagent mixer is made of stainless steel/polypropylene as a monolithic structure, dissolution efficiency is 100%.
Reliable and safe operation, stable performance.
Excellent corrosion resistance: all parts in contact with the medium are made of technical plastics and stainless steel.
Suitable for both powdery, fibrous, poorly soluble, caking-prone materials with high dosing requirements, as well as for the preparation and dosing of liquid materials.
High-efficiency, low-G-value special gear mixer made of stainless steel, preventing long-chain molecules from breaking.
Accuracy, stability and high efficiency significantly improve the quality of the water produced and the reliability of the entire water treatment system, while simultaneously reducing reagent consumption and labor costs.

Review
JY series dosing equipment is designed to meet the needs of the market and customers, as well as to provide production automation in such fields as petroleum, chemical, oil refining, gas production, water supply, thermal power, pharmaceuticals, food processing and others. It uses advanced technology and production processes from the United States, Germany, Japan and other countries, strictly in accordance with the requirements of technological standards and taking into account the actual conditions of China.
JY series dosing equipment is characterized by completeness, advanced technology, high degree of automation, convenient operation, easy maintenance, and the ability to meet the needs of various operating modes. Custom products can also be designed and manufactured to meet specific user requirements.
JY series dosing devices are widely used for dosing reagents in boiler water (ammonia, hydrazine, phosphates), dosing into source water (flocculants, coagulants, acids, alkalis, etc.), dosing into circulating water (corrosion inhibitors, scale inhibitors, fungicides, concentrated sulfuric acid, alkaline solutions, etc.), for chemical additives in oil and gas fields, waste and sewage water treatment, as well as in other operating modes.
The JY series dosing device consists of a solution tank, stirrer, level indicator, dosing pump, filter, damper (buffer), safety valve, various types of fittings, electrical control part, common base with platform and ladder, and pipeline fittings.
Check valve
Complete dispensing devices include the following three categories: simple dispensing device, integrated dispensing device, separate dispensing device.
Simple dosing device
The simple dosing device is equipped with a small dosing pump, stirrer, level sensor and other accessories. All of them are directly installed on the dosing barrel. Thanks to its flexible configuration, small footprint and high efficiency, it is very suitable for use in small dosages. Optional accessories: injection valve, pulsation damper, back pressure valve, control cabinet, etc.
Integrated dosing device
An integrated dosing device means installation in a single unit, that is, the solution tank, agitator, level gauge, dosing pump, control cabinet, ladder platform and other accessories (such as safety valves, dampers, check valves, etc.) are all installed on one channel base.
The metering device combination covers various types, such as "one tank - one pump", "one tank - two pumps", "two tanks - two pumps", "two tanks - three pumps", "two tanks - four pumps", as well as multi-tank configurations with pumps, etc.
Based on the control method, a basic type and an intellectual type are distinguished. The basic type is an open ramp dosing system. The necessary accessories can be selected to ensure more accurate dosing.
Intelligent dosing control system means open-loop control to achieve a fixed proportion. It can also realize closed-loop automatic control based on the set parameter signal and communicate with the superior computer (host computer).
Advantages of an integrated dosing device
1. Aesthetic appearance, varied design, flexible configuration.
2. Stable performance, compact structure, small footprint.
3. Ease of use, high ability to combine.
4. Wide functionality, large selection of accessories, flexible expansion of functions.
5. Ability to design specific dosing system based on user requirements.
Separate dosing device
The separate dosing device is used in some special conditions, such as large dosing volume, specific dosing medium, when it is inconvenient to combine the solution tank and dosing pump in one unit. If the customer has a large solution tank, the dosing pump unit should be installed separately from the solution tank, and then its inlet should be connected by a pipe to the solution tank outlet. Such a device is called a split dosing device. The solution tank may be a large polyethylene container, a stainless steel container, or a cement tank, etc. The pump dosing unit is determined by the number of dosing points, usually it is a single-pump type, a two-pump type (one working, one standby), a three-pump type (two working, one standby), a four-pump type (two working, two standby). The base of the pump dosing unit is made of high-strength channel. The pipeline is secured using brackets and is characterized by its small footprint and rational design.

It automatically dispenses specific chemicals into wastewater to achieve physical, chemical or biological treatment goals.
The fluoroplastic FOB magnetic pump is a chemical process pump that uses the principle of modern magnetic mechanics and transfers force non-contactly using permanent magnets. As the motor rotates, the outer rotor (outer magnetic system) drives magnetic lines of force that pass through the thermowell and cause the inner rotor (inner magnetic system) and impeller to rotate synchronously.
