What are the reasons for the blockage of the external cooler after cleaning?
What are the reasons for the blockage of the external cooler after cleaning? 1. It wasn’t cleaned thoroughly. 2. Ammonia introduction too early; 3. Excessively low ammonia pressure at the outlet. 4. The conveying capacity of the axial flow pump decreases.
It seems that even if it’s not at full liquid level, it can still cause blockages in the pipes
It seems that not having a full liquid level can also cause pipe blockages; it actually has little to do with whether the level is full or not. A full liquid level simply increases the heat exchange area.
1. Low inventory of hot AI tanks. 2. Small opening degree of the cleaning pump valve. 3. Small opening degree of the AI valve for cleaning in the external cooler. 4. Blockages caused by lack of regular tube cleaning, resulting in a large number of blocked tubes. 5. The cleaning pump is running at a low capacity or has tripped
I have a question: why can a low inventory of hot AI tanks also cause the external cooler to get clogged? A low stock level probably doesn’t mean it’s empty, right?
A low inventory means a small quantity; as a result, less heat AI enters the external cooler. Since the amount of ammonia entering the external cooler does not decrease, AI will crystallize within the external cooler, causing blockages.
