What is meant by the phenomenon of "gas plugging" and "cavitation" in centrifugal liquid oxygen pumps for DEAR Liquid air separation unit and what are the hazards?

  After the gas flows out of the expander impeller, there is still a certain speed. This part of mechanical energy without work is called residual speed loss. In order to reduce the velocity of the gas flow at the outlet of the expander, there is generally a section of expanding short pipe at the outlet of the expander impeller. This section of short pipe can reduce the velocity of the air flowing out of the expander impeller, reduce the...
