I would like to ask about the reduced efficiency of the scraper-type thin-film evaporator
Thread Content
Our company uses GX scraper film evaporators; recently their efficiency has declined. Upon inspection, it was found that the lower shaft ends were severely worn, the gap between the F4 bearing and the shaft had increased, and there were scratches on the wall of the lower cylinder. The vacuum level of the system is fine. I’m asking experts for suggestions on how to solve this problem. Thank you! Urgent! Urgent! Urgent! Urgent! Urgent!
It’s eccentric; the bearing needs to be processed again.
The processing is complete, but the result is still not good
Check if there’s a problem with the heating system? Where is your company located? I can go and take a look for you if there’s a chance
Adjust the scraper that has scratches. If the mechanical issues are resolved but efficiency still doesn’t improve, check whether there have been any changes in the process parameters.
There is no problem with the heating system; it is heated by steam, and there is also no issue with the system’s vacuum level.
Upon disassembly, it was found that there was no friction on the scraper, but there were scratches on the inner wall of the cylinder
The jacket has been cleaned, and the temperature is fine
If the scraper gap can be adjusted, adjust the scraper and the bearing. It is estimated that the high degree of eccentricity leads to a decrease in efficiency.
Yes, the four-fluorine bearings below have been lengthened now to try and secure the shaft, but the effect isn’t very noticeable. Do you mean increasing the width of the scraper? Can the length and width of the scraper be customized?
