A recorder for recording temperature in a small biocabin on board the recoverable satellite and the speed of a centrifuge incorporated in the cabin was developed.
This paper introduces the main energy saving technologies of centrifugal pump.And the author proposes a new energy saving technology which is called prerotation regulated by the inlet guide vane.
Supergravity strengthens mass transfer process by using strong centrifuge field instead of gravity field, which has gained wide attention at home and abroad since it came out last century.
