Hi Guys
I've a strange vibration on one of my compressors, when it is running between 15% and 45-50% of capacity ,it vibrate like hell, I'm not very familiar with Frick compressors as I'd usualy worked with Stal compressors. I can definetly say that is not a problem related to liquid refrigerant coming back on the suction line as i switch the compressors with the spare unit and this ones is running fine... I'd contact York service and they siad that up to 11mm/s vibration value is fine , but I don't trust them very much as with our VSM89 chillers warranty problem ,they were more concern to cover them up instead to solve them.....
Anybody has any suggestion or comments?
I'm planning to open the compressor as an apple and replace the berarings and inspect the screw conditions...
Ciao
