During compression, lots of heat is generated. With oil injected screw technology, this heat is approx. 60..80° above ambient. With oil free techonology, this can go up to 180°..200° above ambient.
This is quite some waste heat (80% of shaft input).
Is it feasible to convert part of this heat...
Thanks for all comments and suggestions.
Some extra data:
- it's a screw compressor with 4 lobes on male and 6 lobes on female
- vibration peaks remain at same frequencies, regardless of gear sets (different transmission ratios have been tried)
- motor speed is around 1500 rpm (4 pole AC motor)...
I'm coping with a new compressor drive train showing noise and vibrations peaks at 120, 126th and 162th motor order. I haven't found a plausible explanation for this orders. What can be the cause of such high motor orders? They don't coincidence with any of the typical frequencies one can expect...
