Centrifugal Gas Compress Volute/Casing Temperature
Centrifugal Gas Compress Volute/Casing Temperature
(OP)
For centrifugal compressor, say that Inlet is 150 degF at 20psig and Outlet is 500 degF at 40 psig, I would expect that the Volute temperature would be at least equal to the outlet temperature of the gas.
Probably higher due to efficiency / frictional etc. losses.
Excluding other losses in the motor/drive train/other mechanical elements, is there data that predicts the increased temperature of the volute as a percentage function of the work of compression of the gas for the family of centrifugal compressors?

the compressible fluid is not stated . . . assuming 14.7 for atmospheric pressure, the compression ratio is 1.576 and a temp increase of 350°F . . . possible bad data or otherwise . . .
i recommend contacting the compressor mfg and consult with them. additionally, i fail to understand the purpose of your question.
wait a minute, is this a hofim compressor from DR or a hermetically sealed compressor/motor/drive train unit whereby the compressible fluid is removing heat of compression + frictional losses + misc energy losses? that may explain the higher than normal outlet temps.
again, suggest consulting with mfg or perhaps provide further detail as to the situation being experienced.
good luck!
