Two-stage parallel operation of a centrifugal compressor? Who has experience in this area? Let’s discuss it!

Who has experience in this area? Please give examples!
The two sections operate in parallel, not in two stages; it was a mistake!
Parallel operation of centrifugal units is a common feature in various processes, mainly to ensure the required air volume and maintain the pressure. Keep the curve under control.
Performance curves of centrifugal compressors: 1. Pressure vs. flow rate; 2. Power vs. flow rate. Curves showing changes in key components: 1. Change in the outlet angle of the impeller blades; 2. Changes in the adjustment of the inlet valve; 3. Temperature changes; 4. Changes in inlet pressure; 5. Changes during loading and unloading; 6. Changes under constant-pressure conditions. Each of these curves provides information about the overall performance of the centrifugal compressor, and any changes in these curves can influence your decision-making. By understanding these curves and their underlying principles, you can choose the appropriate equipment without making arbitrary decisions.
The two stages of a single centrifugal compressor can operate in series or in parallel; I am referring to operation in parallel here, not the parallel operation of two compressors.
1. It can be used. But the pressure is low. 2. The first-stage impeller is different from the third-stage impeller. 3. There is a difference in traffic volume. 4. The power will increase or decrease. 5. It is best if designed by the manufacturer.
