Frequencies lower than 50Hz
hi all,
Learned today that there are frequencies lower than 50 Hz. Those ones are mainly (7-12Hz) for Shaft and blades. So I am surprised that we don't touch them in DW for classification. the 50Hz-60Hz are mainly for Auxiliary machinery (pumps). Am I right Compressioncut? Thanks Mau |
