What are the installation requirements of circulating water dosing system and what should be paid attention to?

During the installation of the circulating water dosing system, the nozzle of the dosing pipe shall be against the flow direction and inserted into the center line of the medium pipe. Pay attention to turning on the mixer for mixing to make the added reagent and water mix evenly. The following describes in detail the "installation requirements and notes of the circulating water dosing system".

1、 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.

2、 Precautions for use of circulating water dosing system

1. Since the water treatment system used now takes reverse osmosis as the main process, the main drug used is scale inhibitor. When dosing the water treatment dosing device, pay attention to clean the medicine box first, close the blowdown valve at the bottom of the medicine box, drain the water after cleaning twice, and then start dosing;

2. In the process of dosing the water treatment dosing device, pay attention to turn on the mixer and let it stir to make the added reagent and water mix evenly;

3. During dosing, pay attention to control its speed and stroke. The dosing stroke of the metering pump can be adjusted by turning the adjustment knob of the metering pump counterclockwise to make it rotate to the corresponding scale and ensure that the stroke meets the requirements;

4. After dosing, the water treatment dosing device shall be inspected regularly to ensure that there is no leakage in the dosing system. If leakage is found, it shall be reported in time and maintenance and replenishment measures shall be taken;

5. The operator shall check the water treatment dosing device on time and record the cycle, pay attention to whether the total water inflow and dosing amount of the equipment match, and pay attention that the height of dosing and water replenishment shall not exceed the marked high liquid level;

6. Standby pump, safety valve, calibration column pressure gauge, cleaning pipeline and leakage tank are standard to ensure safe and stable dosing;

7. Some models can realize local configuration, accept the dosage command, automatically run and automatically switch the standby pump to ensure the quality of finished products and save the cost of additives;

8. Long term supporting cooperation with many chemical additives suppliers

9. Products are widely used in app, Liwen, Jiulong, Huafang and other enterprises.
