Product overview:

The automatic dosing system addresses scaling, corrosion, and microbial growth in circulating water systems caused by temperature fluctuations, flow variations, and evaporation concentration. It resolves the limitations of traditional manual dosing methods—such as excessive workload, low precision, and risk of operational instability—through intelligent control. The system enables scheduled and precise dosing of corrosion inhibitors, scale preventives, and biocides. This reduces manual intervention, lowers operational costs, and extends equipment lifespan.

Working principle of automatic dosing device:

1. Add control The dosing pump is controlled by the time-controlled switch and automatically starts and stops according to the preset time (e.g., Monday, Wednesday and Friday). The corrosion inhibitor and scale inhibitor are added in the left barrel three times a week, and the bactericide and algae killer are added in the right barrel once a week.

2. Drug action Erosion and scale inhibition agents: relieve metal corrosion and prevent the formation of scale. Bactericide and algaecide: a broad spectrum of bactericides, inhibit algae reproduction, remove sludge and stabilize pH value.

Automatic dosing device product features:

1. High automation with manual/automatic mode switching. Flexible dosing cycles and timing can be set via timed switches.

2. Superior reliability: The PE anti-aging dosing tank features corrosion resistance and a service life exceeding 10 years. The mechanical diaphragm metering pump ensures precise flow control for various operational conditions.

3. Safety protection: A low-level alarm system prevents pump damage from idle operation. Optional accessories (e.g., conductivity meters, pH meters) enable real-time water quality monitoring, automatically triggering discharge or shutdown when parameters exceed limits.

Structure composition of automatic dosing device:

1. Core components

Intelligent control box: the control center, coordinating the work of each part.

Mechanical diaphragm metering pump: accurate dosing, support for stepless speed adjustment.

PE filling tank: anti-chemical corrosion, semi-transparent design for easy observation of the remaining quantity.

Low level alarm device: drug shortage warning, protect equipment safety.

2. Select accessories function

Conductivity meter: monitor the concentration ratio and control the amount of water replenished for drainage.

PH instrument: adjust the acid and alkali degree of water quality, adapt to different pipe materials.

ORP instrument: detect the REDOX potential and evaluate the stability of water quality.

Sewage discharge valve/corrosion rate meter: automatic sewage discharge and corrosion monitoring, optimize the strategy of chemical dosage.

Automatic dosing device control mode:

1. Time Control Settings Adjust the clock, day, and on/off times via buttons, supporting daily/weekly multi-period programming. Example: Apply corrosion inhibitor from 8:00 to 9:00 on Monday, repeat on Wednesdays and Fridays; apply sterilizer separately on Mondays.

2. Operation Modes Automatic mode: Runs according to preset programs. Manual mode: Temporary circuit activation/deactivation for debugging or emergency use.

Maintenance of automatic dosing device:

1. Daily maintenance Drain the residual agent in idle equipment. Check the lubrication of metering pump regularly (no oil needed for electromagnetic pump). Clean the blockage of bottom valve to ensure smooth pipeline.

2. Special requirements Outdoor installation should be rainproof and frostproof (the liquid in the pipeline should be drained in winter). Before initial use, air should be discharged to avoid gas blockage affecting the discharge.

Other notes on the automatic dosing device:

Safety tips: Outdoor equipment should be well protected from rain and freezing to avoid failure caused by environmental problems.

Parts selection: Select conductivity meter, PH meter, etc. according to requirements, and professional guidance is needed for agent ratio.

The above is the relevant knowledge of automatic dosing device, I hope to help you!
