How to install the circulating water dosing system and what should be paid attention to?

For the installation of circulating water dosing system, the drug dissolving box is the outlet of the drug dissolving box which is higher than the inlet of the drug adding pump. The console should be clean and bright where the original strong magnetic field is. In addition, when using, the height of the drug adding and water replenishing should not exceed the marked high liquid level. So, let's introduce the relevant contents in detail.

1、 Installation requirements of circulating water dosing system

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

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

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

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

5. The control cabinet shall be clean, bright, non corrosive, far away from strong magnetic field, with temperature less than 45 ℃ and humidity less than 85%.

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

2、 Matters needing attention in the use of circulating water dosing system

1. Since the main process of the water treatment system is reverse osmosis, the main drug used is scale inhibitor. When dosing the water treatment dosing device, the medicine box should be cleaned first, and the drain valve at the bottom of the medicine box should be closed. After cleaning twice, the water should be drained before dosing;

2. In the process of adding chemicals to the water treatment dosing device, attention should be paid to turning on the mixer to make it mix evenly with water;

3. When dosing, pay attention to control its speed and stroke. The dosing stroke of the metering pump can be adjusted by turning the adjusting 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 any leakage is found, it shall be reported in time and maintenance and supplementary measures shall be taken;

5. The operator should check the water treatment dosing device on time and record the cycle, pay attention to whether the total water inflow and dosing amount match, and pay attention to the height of dosing and make-up water not to exceed the marked higher liquid level;

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

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

8. Long term cooperation with many chemical additives suppliers

9. The products are widely used in app, Liwen, nine dragons, Huafang and other enterprises.
