Air-cooled island vacuum issue
Thread Content
In summer, due to the high ambient temperatures, it is not possible to achieve a vacuum level of -70 kPa on the air-cooled island; currently, the actual vacuum level is around -60 kPa. I would like to ask the experienced colleagues for any good suggestions on how to improve this situation. The fins have already been cleaned, so leaks in the equipment’s pipelines can be ruled out
Try increasing the power of the exhaust pump. Theoretically, both the exhaust pump and the air cooler serve to reduce the exhaust pressure.
Add a spray system to reduce fin temperature
There are no problems on this day, right? It’s still due to the high ambient temperature!
