Automatic dosing device

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. Problems such as deposition of deposits (that is, scaling on the surface of the system), large-scale growth of microorganisms, and equipment corrosion are inevitable on the heat sink. 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:

Auto The dosing device is mainly composed of solution tank, agitator, metering pump, liquid level gauge, electric control cabinet, pipeline, valve, Y

How the automatic dosing device works:

Time Control Mode:	Indicator control mode:
Use the time-controlled switch to control the timing closing and opening of the blowdown valve and metering pump to achieve timing blowdown , the purpose of dosing.	Use the change results of water quality indicators to control the real-time closing and opening of sewage valves and metering pumps to achieve The purpose of automatic sewage discharge and automatic dosing.
Programming time control dosing and online monitoring control dosing and dual control dosing, Independent switching, the implementation of automatic dosing!

Automatic dosing device function:

Hard scale control	Microbial Control	Corrosion Control
Add a small amount of scale inhibitor and dispersant suitable for the water quality of the system to the circulating water, namely It can solve the problem of hard scale deposition.	Introduce suitable bactericidal and algaecide to control the microbial content in the circulating water within the specified range. Keep the microbial metabolism slime within the allowable range and prevent the formation of slime.	Add a lower amount of compound corrosion inhibitor to the circulating water to adapt to the water quality of the system, That is, the corrosion of equipment can be controlled within the range specified by 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, degree of automation High, 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, long service life, all parts in contact with the liquid are made of PEEngineering plastics, resistant to strong acid, strong 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, user according to Requirement optional: 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.

Composition of dosing device system

The automatic dosing device is mainly composed of a solution tank, a Mixer (optional), metering pump, control cabinet, pipeline, pressure gauge, buffer, Ytype filter, Level gauge, level sensor (optional), conductivity (optional), PHmeter (optional), Corrosion online detector (optional), bracket and other components.
All components are assembled in one rack On the other hand, the compact and reasonable combination into an independent dosing unit greatly reduces the workload of chemical design and on-site installation and reduces the floor space.
Solution tank with low level stop pump Protective function.
can realize on-site manual adjustment of dosing and Automatic dosing, all electrical appliances and instruments are assembled in the electrical cabinet, with compact structure, convenient commissioning and operation.

Notes on the installation of automatic dosing device

appropriate Working and Environmental Conditions

1. Indoor temperature5-40℃.

2. The installation and operation site of the automatic dosing device should be free from severe vibration and shock, no corrosive gas, and away from strong magnetic fields. span>

3. The water entering the dissolving tank must be tap water or higher grade water, the water temperature 1-40℃.

Notes on the use of automatic dosing device:

Check before power on

1. Check all pipes and valves are in normal working condition.

2. Check that the metering pumps and instruments of each automatic dosing device are in normal working condition.

3. Check that the electrical equipment is in normal working condition.

(1) Put the water treatment chemicals in the warehouse according to the signs, and remember to use them incorrectly and confuse them.

(2) When operating, be sure to wear protective equipment to avoid medicine and eyes and skin contact. If the agent comes into contact with the skin accidentally, rinse immediately with plenty of water.

Maintenance precautions for automatic dosing device

The pipeline should be kept unblocked, and the timing should be irregular. Check the connection parts of the device, filters, inlets, outlets, etc., to observe whether there are deposits in these parts. If these symptoms are found, they should be cleaned up in time.
Regularly check whether the feeding port of the metering pump is blocked , Regular cleaning of pipelines and filters to prevent clogging.
Stirring device, check whether the stirring pump rotates flexibly , Whether the impeller is twisted and deformed, and whether the coupling sleeve is loose, so as to avoid excessive torque of the shaft and consume the stirring power. If it is damaged, it should be replaced in time.
Check the pressure gauge and each pipeline valve, to avoid leakage.
