After the reverse osmosis purified water treatment equipment is stopped, it needs to be cleaned for a period of time. The flushing time can be set according to the length of system shutdown time. At the same time, consideration should be given to whether to take shutdown protection measures. For some systems with shutdown protection measures, before restarting the system, the protective agent added to the system should be discharged first, and then the protective agent should be rinsed clean before starting the system. If no protective agent is added during shutdown and shutdown protection measures are taken, the water in the system is generally water. However, due to different system downtime, the water in the system may have deteriorated. Therefore, before starting, non pressure flushing can also be used to drain the water. If the water in the system is insufficient and contains air, there should be no pressure to flush and discharge the water and air from the system. This is mainly because the air may cause "water hammer" phenomenon, which can damage the membrane components.

Do you know what maintenance work needs to be done after the pure water treatment equipment is shut down? Now let's introduce it to you.

1. Record the operating parameters of the refrigerator before shutting down.

2. Collect oil samples and analyze them in the laboratory designated by Party A.

3. Check or replace the refrigeration oil to the required level.

4. Replace the oil filter, check or replace the pressure sensor, temperature sensor, and water flow switch.

5. Check the refrigeration system, replace the drying filter, and check the refrigerant consumption.

6. Check the pressure reducing valve and pipeline, perform pressure testing, and check for system leaks.

7. Remove the back cover of the condenser and evaporator, check for any abnormalities, and clean the pipes of the condenser and evaporator.

8. Check the oil/condenser pressure converter.

9. Check the electrical wiring connections inside the startup cabinet and control cabinet for firmness, and ensure stable and clean contact of contactors and relays.

10. Check and control the system; Adjust system settings as needed to maintain normal operation of purified water treatment equipment.
