Sealed Motor Driven Centrifugal Primary Fluid Pump With Secondary Fluid Flow For Cooling Primary Fluid
US Patent:
6554586, Apr 29, 2003
Filed:
Mar 30, 2000
Appl. No.:
09/539144
Inventors:
Ferdinand Lustwerk - Bedford MA 01730
International Classification:
F04B 1700
US Classification:
417366, 376220
Abstract:
A sealed submersible electric motor driven centrifugal primary cooling fluid pump is entirely submersible in the electron beam tube cooling system of an X-Ray system incorporates a heat exchanger in the pump, wherein primary cooling fluid (oil or other high dielectric strength fluid) that is pumped in the sealed pump through an annular primary fluid passage therein is cooled by secondary cooling fluid flowing through an annular passage wrapped around the primary fluid annular passage over the length of the primary fluid annular passage, providing a compact unit of pump and heat exchanger.
