What should the pressure ratio per stage of a centrifugal compressor not exceed? Why?
After reading some of your posts, it seems that the goal of learning * has shifted a bit. Some issues are related to design; for example, this issue involves the drive balance between the impellers at various levels acting on the main shaft, or among multiple shafts, as well as other factors that need to be taken into consideration. Problems in this area have no inherent connection with operations. It is recommended to focus one’s efforts on learning the principles of the equipment.
The pressure ratio in each stage is still limited by the temperature between stages; otherwise, if the temperature is too high, the cooling water cannot bring it down
