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

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。
