Introduction of automatic dosing device
The automatic dosing device is also known as automatic dosing equipment and chemical dosing equipment. After the air conditioner runs for a long time, if the automatic dosing device is not used, the chilled water, cooling water system, refrigeration host and fan cooling plate of the air conditioner will inevitably appear. Sediment adhesion (that is, scaling on the system surface), microbial proliferation of slime and equipment corrosion problems. 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.

Working principle of 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 filter, 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.

Working mode of automatic dosing device:

Automatic dosing device function:

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), PHInstrument (optional), corrosion online detector (optional), bracket, etc.
• 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.

Notes on the installation of automatic dosing device

Good job and environmental conditions

    1. Indoor temperature5-40℃.

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

    3. The water entering the dissolution 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, 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, remember to use them incorrectly , confusion.

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

Maintenance precautions for automatic dosing device

1. The pipeline should be kept unobstructed, and the pipeline should be kept unobstructed from time to time. Check the connection parts of the device, filters, feed ports, discharge ports, etc., and observe whether there are deposits in these parts. If these symptoms are found, they should be cleaned up in time.
2. Regularly check whether the feeding port of the metering pump is blocked. For pipelines, filters are cleaned regularly to prevent clogging.
3. 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 shaft torque and consume stirring power. If it is damaged, it should be replaced in time.
4. Check the pressure gauge and each pipeline valve to avoid A leak has occurred.
