Key words：Water Filter、UV Sterilizer、Ion Exchange Water softener

The intelligent online dosing device is a set of equipment matched with the central air-conditioning circulating water treatment, including intelligent control box, dosing metering pump, dosing barrel, optional online control instruments and other parts. The dosing pump is controlled by a time-controlled switch, and regularly adds bactericidal and algae-killing agents, corrosion and scale-inhibiting agents to the system to prevent bacterial growth and algae reproduction, so as to achieve the effects of sterilization, algae removal, scaling and anti-scaling. The intelligent online dosing device can dosing the medicament into the circulating water system regularly, quantitatively and automatically, which greatly reduces the amount of labor, realizes scientific management, and reduces operating costs.

Introduction to automatic dosing device

Automatic dosing device is also known as automatic dosing equipment and chemical dosing equipment. The refrigerating main engine and the fan cooling plate inevitably have problems such as deposition of deposits (that is, scaling on the surface of the system), a large number of microorganisms multiplying slime and equipment corrosion. An automatic dosing device must be installed to effectively sterilize the cooling water, remove scale, and prevent corrosion. It can also be treated by physical treatment equipment such as a broad-spectrum induction water processor or an electrical descaling instrument, an ion bar water processor, and a bypass water processor.

The working principle of the automatic dosing device:

The automatic dosing device is mainly composed of solution tank, agitator, metering pump, liquid level gauge, electric control cabinet, pipeline, valve, Y type filters, etc. Directly configure the required concentration of the agent in the solution tank, and use the metering pump to deliver the prepared solution to the dosing point system. By adjusting the stroke of the metering pump to change the dosing volume of the metering pump, targeted design and configuration of necessary components can be carried out according to the requirements of different technological processes of users, and functions such as automatic remote control can be realized.

How the automatic dosing device works:

Time Control Mode: span>	Indicator control mode: span>
Use the time-controlled switch to control the timed closing and opening of the drain valve and metering pump , to achieve the purpose of regular sewage discharge and dosing.	Use the change results of water quality indicators to control the real-time control of sewage valves and metering pumps It can be closed and opened to achieve the purpose of automatic sewage discharge and automatic dosing.
Programming time control dosing and online monitoring control dosing double Control dosing, switch autonomously, and implement automatic dosing!

Automatic dosing device function:

Hardscale Control	Microbial Control	Corrosion Control
Add a small amount to the circulating water to adapt to the scale inhibition of the water quality of the system Dispersing agent, which can solve the problem of hard scale deposition.	Introduce suitable bactericidal and algaecide to control the microbial content in circulating water Within the specified range, keep the microbial metabolism slime within the allowable range to prevent the formation of slime and soft scale.	Add a lower amount to the circulating water to adapt to the compounding of the water quality of the system Corrosion inhibitor can control the corrosion of equipment within the range specified in the standard. For carbon steel stainless steel system, when the formula of scale and corrosion inhibitor is preferred, it has been compounded into the formula, which can solve the problem of equipment corrosion, if there is copper equipment in the system.

Design Features

1, high degree of automation, uniform and accurate dosing. The dosage is controlled by the microcomputer dosing controller (metering pump), except for the regular dosing of the medicine into the dissolving tank, no manual operation is required, which saves a lot of manpower and makes the dosage more accurate.

2< font face="宋體(tǐ)">, long service life, all parts in contact with the liquid are made of PEEngineering plastics, resistant to strong acid, alkali and aging. The driving device is not in direct contact with the liquid medicine, the pump body is completely closed, and the injection molding is performed at one time, and there is no problem of liquid medicine leakage.

3. Users can choose according to their needs: agitator, PLC, temperature, PHOn-line monitoring of PH value and conductivity can achieve accurate and uniform measurement, effectively control the concentration ratio, and intuitively reflect the water quality dynamics.

The composition of the dosing device system

The automatic dosing device mainly consists of a solution tank, a mixer (optional), metering pump, control cabinet, pipeline, pressure gauge, buffer, Ytype filter, liquid Level Gauge, Level Sensor (Optional), Conductivity (Optional), PHGauge (Optional), Corrosion On-line detector (optional), bracket and other components.

All components are assembled on one rack , compact and reasonable combination into an independent dosing unit, which greatly reduces the workload of chemical design and on-site installation and reduces the floor space.

The solution tank is equipped with low level pump stop protection Features.

can realize local manual adjustment and automatic dosing Dosing, all electrical appliances and instruments are assembled in the electrical cabinet, with compact structure, convenient commissioning and operation.
