Plate heat exchanger failure

This post was last edited by ly6721 on 2017-4-6 at 22:58. Our factory has a plate heat exchanger, and after it was put into use this time, it was found to have poor heat exchange performance. The specific fault symptoms are shown in the figure; it is a temperature distribution chart taken with a thermometer on-site. Experts, please help determine the cause of the problem – could it be scaling on the heat exchanger? Is the partition cracked again? If scaling occurs, wouldn’t the temperature drop first and then rise again? Is it still a problem with the partition?
You can give it a try yourself; if the plate is damaged, water will definitely leak and flow to the other side. It’s either leaking, clogged with scale, or blocked
Plate heat exchanger? {:3_46:}
Check whether the usage method is correct and if there is any bias current The cooling temperature should be adjusted using return water; if the return water is pressure-free, it may cause deviation in flow. Also, it is necessary to understand the structural principle of this cooler. For reference
How long has it been in use? It seems that the heat exchange efficiency is low. Could it be due to poor water quality or severe scaling?
It’s a tubular type, right! Generally, in such cases, as you yourself said, the first thing to check is whether there’s a problem with the partition; if not, it’s likely that there’s a blockage. I’m also a beginner, so I don’t have any good suggestions
