Can a low suction pressure in a centrifugal compressor cause a high outlet temperature? Let’s exchange ideas with the big brothers who know more
No. The reason for the high outlet temperature of centrifugal compressors is gas compression; the higher the compression pressure, the higher the temperature. It’s best to discuss the issues encountered on site. For reference.
If the low inlet pressure is caused by a low flow rate, (with the speed remaining constant) since the work done by the unit is fixed, the excess kinetic energy will be converted into heat energy, resulting in an increase in the outlet temperature to a certain extent. Actually, in similar situations where the pump fails to deliver the required flow rate, are there any similar symptoms?

A low suction pressure in a centrifugal compressor, with constant outlet pressure and an increased compression ratio, can lead to high outlet temperatures.
