The dosing device of the metering pump is mainly composed of liquid tank, hydraulic metering pump, agitator, magnetic turnover plate level meter, motor control cabinet, online conductivity meter, online PH meter, online ORP meter, online chlorine analyzer, valve, blowdown valve, air pressure reducing valve, Y-type filter, total flow calibration column, valve, pipeline and spare parts, installation cable in the machine equipment, machine equipment support frame and Base service platform, etc. Solid or liquid drugs are added to the dissolving tank, and then the industrial production water is added to mix and melt according to the proportion, and the drug is added to the drug delivery point by the dosing pump. The addition control method is manual, or it can be automatically added according to the control data signal exported by the on-stage system software.

The principle of circulating water dosing equipment

The dosing and metering pump is controlled according to the time-controlled switch, and the slime stripping agent and corrosion inhibition and scale inhibitor are added to the system software on time to prevent the growth of germs and the breeding of algae, so as to achieve the role of bacteria and algae removal, scale cleaning and scale inhibition.

Non-reducing pesticide fungicides should be used in circulating water, which have the ability of eliminating bacteria and algae, can effectively and reasonably control the growth and development of bacteria and algae in water and the growth and development of slime, and have good slime detachment and dispersal and diffusion effects, can remove algae plants and improve slime, and have excellent bactericidal effects in different PH values. In addition, it has the ability to remove oil, odor and corrosion inhibition.

Non-reducing pesticide fungicides have small side effects, no cumulative toxicity, and dissolve water, and will not be affected by the hardness of water, so they are widely used in the circulation system cooling system in the petrochemical industry, chemical industry, power installation engineering, textile industry and other fields to control the growth of circulation system cooling water bacteria and algae, which is effective and reasonable to eliminate potassium thiocyanate recovery bacteria. As a non-reducing slime stripping agent and slime stripping agent, it can also be used as a dyeing agent for the color of acrylic chemical fiber and its tenderness before production and processing in the textile industry.

Corrosion and scale inhibitor is a water treatment agent that reduces corrosion and prevents scale accumulation of machinery and equipment. The drug is mainly used in the heating furnace and refrigeration circulation system of the water machine equipment, so that the circulating water is not easy to cause scale and erosion of the machine equipment, increase its service life, reduce costs and consumption.

Second, the application scope of circulating water dosing equipment
