What causes this phenomenon in the plates of a plate heat exchanger?
Thread Content
What causes this phenomenon under the compressor oil cooling conditions? Please help analyze it.
No reply? Is no one knowing? Is there still a lack of enthusiastic people?
I guess no one knows that we deal with plate exchanges; I’ve never encountered such a situation before. It’s also quite regulated, making it difficult to analyze. The hydraulic press used in our company hasn’t been disassembled in five years, so I’m not sure if the same thing will happen there. Initially, it seems that these marks are formed at the points where two plates intersect; if you connect those points diagonally, you can see that they form a herringbone pattern. I don’t understand why the intersection points look like that – is it because the flow rate is too high? Severe wear at the intersection? It’s really hard to say; I can’t help you
Excessive pressing force on the plates, direct contact between the plates, and pitting corrosion caused by interference due to the size and angle of the plates
It should be related to the manufacturing process; ask the manufacturer
The reason has been identified. Because something was accidentally added to the water, the lithium chloride content exceeded 200, which is above the allowed limit.
Is it because the sealing performance of the gasket is poor, and the compression force at the site is too high, causing the plates to be in light contact with each other?
