safety water seal

After the safety water seal is broken, I want to add water and re-establish the water seal. How to do this?
Yes, re-establish the water seal without stopping the vehicle.
What material is used for safety water seal? The simplest thing is to re-patch it with acid-resistant cement, which can cope with it for a period of time, and then deal with it next time when it is stopped for a short period of time.
Cover the air inlet with a board and continue to add water to naturally re-establish the water seal.
Filling up water without stopping? Is it safe? Will it cause a large amount of water to be sucked into the electric defogger? Personally, I feel that even if it can be added, the current negative pressure condition of the drying inlet must be considered. It is best if the fan air volume can be slightly reduced to prevent the negative pressure condition of the electric defogger from exceeding the safe value after water sealing, causing an explosion.
Reduce the system load, open the leak hole near the water seal, and add a large amount of water. However, adding water without stopping the car will often exceed the originally set negative pressure value, and the exceeded value cannot be determined. ； The scary thing is that if the water seal is removed, it means that the resistance of the equipment or pipes in front of the water seal has increased or is blocked. In this way, the electric defogger is in danger of exploding when driving (it happens a lot) ； Stop and check the problem before driving again.
Connect a fiberglass pipe from the outlet of the fan to the entrance of the drying tower. After the water is pumped and sealed, open the valve immediately. The negative pressure will drop immediately. Moreover, opening the valve during the short-term roasting furnace can also maintain the conversion temperature and reduce the investment in electric heating.
