Two-stage liquid ring pump with rotating liner in first stage supported by liquid from second stage.

摘要

A two-stage liquid ring gas pump has a rotatable liner supported on a liquid bearing in the first stage housing. The liquid for the liner bearing is withdrawn from the second stage liquid ring and is therefore at a pressure which is high enough to support the liner for rotation without the need for any other component such as a liquid pump to pressurize it for that purpose. <IMAGE>
