What is the working process of water treatment dosing device?

When using the water treatment dosing device, add enough dry powder in the hopper. Pay attention to cleaning the medicine box before starting dosing. At the same time, pay attention to the height of dosing and water replenishment. The following describes 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 dry powder. At the same time, the solenoid valve of the water inlet pipe is opened. After the dry powder is soaked in the pre wetting device, it flows to the mixing tank by gravity for mixing and mixing.

2. After preliminary mixing, the mixed drug solution flows to the homogeneous curing tank through the overflow weir for re mixing and combination; After effective and gentle low-speed stirring, the drug solution meets the requirements of homogenization, ripening and activity; Then it flows to the solution storage tank through the overflow weir for dosing.

3. When the solution storage tank is filled with drug solution, the liquid level switch sends a signal and the dry valve and solenoid valve are closed automatically.

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

5. When the liquid level in the solution storage tank reaches the set low liquid level, the liquid level switch sends a signal, and the dosing device starts to automatically repeat the above steps to ensure that there is enough liquid medicine in the solution storage tank.

2、 Precautions for water treatment dosing device

1. Since reverse osmosis is the main process of water treatment system, 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, so as to ensure the quality of finished products and save the cost of additives.
