What are the characteristics of circulating water dosing system and how to install it?

The circulating water dosing system can be widely used in various large-scale water-cooled central air conditioning systems to realize the functions of automatic dosing and automatic blowdown of all chemicals. The following describes in detail the "characteristics and installation requirements of circulating water dosing system".

1、 Characteristics of circulating water dosing system

1. It is widely used in open cooling water system, closed chilled water system and all kinds of large water-cooled central air conditioning systems;

2. Realize the functions of automatic dosing and automatic blowdown of all agents such as scale inhibitor, corrosion inhibitor and bactericide;

3. Online detection items can include pH, ORP, conductivity, residual chlorine, turbidity, corrosion rate and reagent concentration;

4. It can realize wireless remote transmission of all online parameters and equipment operation status and real-time status monitoring of mobile phone;

5. Online instruments, metering pumps and pipe valves shall be selected from international well-known brands to ensure the long-term stable operation of the system;

6. Long term supporting cooperation with many domestic and foreign water treatment pharmaceutical manufacturers.

2、 Installation requirements of circulating water dosing system

1. The nozzle of the dosing pipe shall reverse the flow direction and be inserted into the center line of the medium pipe. The dosing pipe is 10-15mm stainless steel pipe, and about 10 2mm small holes are evenly opened around the pipe end accessories.

2. The sample tube is countercurrent inserted into the medium tube through 3 / 4, and several small holes with a diameter of 3mm are drilled in 1 / 3-2 / 3 of the end of the sample tube to increase the representativeness of sampling.

3. The distance between the dosing inlet and the sampling port should be 10-15m.

4. The length of the sample water pipeline between the sampling point and the electrode of the pH meter should be greater than 20m. Since most power plant pipelines have been finalized and it is inconvenient to change, this situation has been fully considered in the program design scheme of the controller.

5. The control cabinet shall be clean, bright and free of corrosive gas, away from strong magnetic field, with temperature less than 45 ° C and humidity less than 85%.

6. The drug dissolving box shall be installed so that the drug outlet is higher than the drug inlet of the dosing pump.
