Requested the balance report for a compressor rotor (see attached). Trying to understand the OEM’s logic on the report.
- OEM uses G 1.6 for low speed (ISO 1940/1). My cal is G 1.9
- OEM uses E 1.25 µm. My cal is 1.23 µm
I do appreciate this is ‘splitting hairs’; however, would like to know how the OEM achieves these values. Are the OEM figures set values established ‘in-house’ of this rotor and others of similar construction or are my cals incorrect?
