四、加药步骤

Four, adding medicine steps

1、初次加药应先清冼加药箱。清冼时关闭加药箱底部排污阀，注水清洗后打开排污阀把水排空，清冼两遍后开始加药。

1, the initial dosing should be cleaned with medicine. When cleaning, shut down the bottom drain valve of the filling box, open the drain valve and emptying the water after water injection, and start adding medicine after cleaning two times.

2、调整计量泵的加药冲程

2. Adjust the dosing stroke of the metering pump

逆时针转动计量泵冲程调整旋钮至相应刻度。

Counter clockwise rotation of the metering pump adjustment knob to the corresponding scale.

3、配药

3, dispensing

检查关闭加药箱底部排污阀，根据加药箱内的有效体积和计量泵的实际工作出力，计算出PTP-0100的加入量。从加药箱的加入口加入药剂，打开进水阀稀释至最高液位刻度处，关闭补水阀。

Check the bottom drain valve of the dosing box. According to the effective volume in the dosing box and the actual working force of the metering pump, the amount of PTP-0100 is calculated. From the entrance plus kits add medicament, open the inlet valve to the highest level of dilution scale, close water supply valve.

例：反渗透给水流量160m3/h，计量泵流量为 22 L/h，将计量泵冲程调整至 40%，则实际出力为 22 L/h×40%=8.8 L/h

Example: reverse osmosis water supply flow 160m3/h, metering pump flow rate of 22 L/h, the metering pump stroke adjustment to 40%, the actual output is 22 L/h x 40%=8.8 L/h

加药箱有效容积600升。

The effective volume of the dosing box is 600 litres.

加药箱中应加入PTP-0100浓缩液的体积：

The volume of the PTP-0100 concentrate should be added to the dosing box.

4、打开加药箱搅拌电机，将药剂搅拌均匀后，停电机。

4, open the charging box to stir the motor, stir the medicine evenly, stop the motor.

5、打开计量泵进出口阀门，打开计量泵开关，药剂加在保安过滤器之前。RO停运后，关闭计量泵。

5, open the inlet and outlet valve of the metering pump, open the metering pump switch, and add the agent before the security filter. After the RO is stopped, the metering pump is closed.

6、定期巡查加药系统有无泄漏，有泄漏及时解决。检查计量泵的加药量是否准确，加药箱液位下降与计量泵计算加入量是否一致，若不一致及时计算调整。

6, regular inspection of the drug delivery system leakage, leakage in time to solve. Check whether the dosage of the metering pump is accurate, the drop of the liquid level of the dosing box is consistent with the calculation of the calculation of the pump, and if it is not consistent and adjusted in time.

7、每月记录检查周期总进水量与加药量是否匹配。

7, each month records whether the total intake of water is matched with the dosage.

8、加药箱补水时注意不要超过最高液位。

8. Pay attention not to exceed the highest level when adding water.

9、加药箱设置有低液位报警时，中控PLC如果设置为低液位报警后停加药泵并切换到备用加药箱及计量泵加药。第二次配置PTP-0100溶液时，加药箱的体积以实际容积计算。

9, when the dosing box is set with low level alarm, the medium control PLC will stop adding the medicine pump and switch to the spare addition case and the metering pump if it is set to the low level alarm. The second configuration of the PTP-0100 solution, and chest volume calculation with actual volume.

如加药箱直径为1m，则实际容积为：

If the chest diameter is 1m, the actual volume of:

V=S×h=ЛR2h=3.14×0.5×0.5×h=0.785h(升)

V=S * h= C. R2h=3.14 * 0.5 * 0.5 * h=0.785h (L)
