What do we mean by rewheel? 1

Rewheel datasheet?

Your question is vague, but for a centrifugal compressor, a rewheel may be required to accomidate different conditions (flow, pressure, MW, etc).

My experience is just to complete a new compressor datasheet (i.e. modify the process data on the original datasheet) to reflect the new conditions. The manufacturer will take this data and figure out the new wheels and diapraghms that are needed. At the plant engineer level there is not a datasheet for specifying individual wheel conditions.

In case you didn't pick it up from sshep's post, the "wheel" of a centrifugal compressor is the "impeller". "Rewheeling" is changing the impellers.

Thanks sshep and zdas04 for answering

Yup, didn't get the wheel's meaning.


Thanks. Blessings!
