Loading of the centrifugal compressor
Thread Content
How is the load generally applied to a centrifugal compressor without guide vanes, that is, from full backflow to the applied load? Should the speed be adjusted manually or the surge valve? Or some other form
“Should the speed be adjusted manually or the surge valve? ”Literally speaking, your centrifugal compressor does not have guide vane control, and that is because the regulation is achieved by adjusting the speed of the variable-frequency motor, thereby gradually increasing the speed and thus the load. This form is the easiest to adjust. The check valve or relief valve is only needed for adjusting the reference pressure.
Well, is that to manually increase the speed when increasing the load?
Adjust manually? It still relies on automatic adjustment by the program
Increase speed first when boosting voltage, and reduce voltage first when slowing down
