Abstract:
An apparatus for testing a leakage rate within a recuperator core, wherein a rate of decay has a predefined acceptable rate and a predefined rejection rate for said recuperator core, said recuperator core having a plurality of components, such components being a plurality of cells being welded one to another, said apparatus comprising:a platform defining a first end and a second end, a first surface of the platform extends between said first end and said second end, a first support portion being attached to said first surface and a second support portion being spaces from said first support portion and each being attached to said first surface; a pair of sealing mechanisms, one of said pair of sealing mechanisms having a rod end of a pressure member attached thereto and being movable in an infinite number of positions resulting in said one of said pair of sealing mechanisms being movable between an open or non testing position and a closed or testing position, in said closed or testing position a reservoir being formed; a pump being operatively connected to at least one of said pair of sealing mechanisms; a monitoring system being operatively connected to said platform, said pair of sealing mechanisms, said reservoir and said pump; and a readout station being operatively connected to said monitoring system, said reservoir and said pump.
