What is the process of water treatment dosing device and what should be paid attention to?

In the work of water treatment dosing device, first add enough dry powder in the hopper, then mix and combine; It should be noted that the main drug used is scale inhibitor, and the medicine box should be cleaned when using. The following is a detailed introduction to the working process and precautions of water treatment dosing device.

1、 Working process of water treatment dosing device

1. The hopper is filled with enough dry powder, and the dry powder in the hopper is transported to the pre wetting device from the start of dry mixing. At the same time, the solenoid valve of the water inlet pipe is opened, and the dry powder is soaked in the pre wetting device and then flows to the mixing tank by gravity for mixing and mixing.

2. After initial mixing, the mixed solution flows through the overflow weir to the homogenization curing tank for further mixing and combination; After effective and gentle stirring at low speed, the drug solution reached the requirements of homogenization, ripening and activity; And then it flows into the solution storage tank through the overflow weir, which can be used for dosing.

4. The dosing pump is started and the solenoid valve is opened to add the solution to the required equipment.

5. When the liquid level in the solution storage tank reaches the set low level, the liquid level switch will send a signal, and the dosing device will automatically repeat the above steps 1, 2 and 3 to ensure that there is enough liquid in the solution storage tank.

2、 What problems should be paid attention to when dosing in water treatment dosing device

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.
