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?

  The cavitation of centrifugal pumps is very harmful. It causes great stress on the surface of the impeller and also reduces the head of the pump of small air separation unit, increases the power and reduces the efficiency. Therefore, measures should be taken in the process of use to avoid cavitation as far as possible. In order to avoid cavitation of small air separation unit, in the process design, should make the liquid into the pump before a certain degree of subcooling, while the pum...
